A connector includes a housing in which a terminal fitting is stored, and a cover. A guiding structure configured to guide the housing and the cover in a connection direction, and a holding structure configured to hold the housing and the cover at a connection completed position are provided between the housing and the cover. The guiding structure includes a wedge guiding protrusion provided to the cover, and a wedge guiding groove provided to the housing. The wedge guiding protrusion and the wedge guiding groove are formed to have a gap between a protrusion-side wall surface and a groove-side wall surface disposed opposite to each other in each of two pairs. The holding structure includes a press-fit protrusion being configured to hold the wedge guiding protrusion and the wedge guiding groove in a press-fitted state when the housing and the cover are at the connection completed position.

Connector including guiding structure between cover and housing

A connector () includes a terminal, a housing () that accommodates and holds the terminal and is engaged with a mating housing (Ch) by being releasably locked by causing a locking portion () to be locked to a locked portion () provided in the mating housing (Ch) when an engagement state with a mating connector (C) is a complete engagement state, and a detection member () that is assembled to the housing () and is relatively movable in an engagement direction and a detachment direction with respect to the housing () between a main locking position when the engagement state is the complete engagement state and a locking release position when the engagement state is an engagement release state in which the complete engagement state is released.

Connector

Disclosed is an electronic component which maintains good connection between a circuit board and connection terminals and provides size reduction. The electronic component includes a circuit board, a pair of connection terminals, and a housing with the pair of connection terminals mounted thereon. The circuit board is provided with a plurality of terminal sections connected to the connection terminals. Each connection terminal is provided with a spring member formed to be elastically deformable and which sandwich the terminal sections between them. A rib is provided in the housing, wherein the rib is provided between through-holes through which each of the pair of connection terminals pass, and whereby the rib is formed in convex shape, towards the circuit board and away from a bottom section of a substrate housing section in which the circuit board is housed, and the rib penetrates a plurality of terminal sections.

Electronic component

A female connector housing is provided with a plurality of terminal accommodating chambers. Each of the terminal accommodating chambers is provided, on its front face, with a terminal insertion opening through which a male terminal is to be inserted. Each of the terminal accommodating chambers is provided, on its rear face, with a wire withdrawal opening. In the terminal accommodating chamber which is intended to accommodate no terminal, there are provided a first shielding wall which surrounds an erroneous-insertion allowable space allowing the male terminal to be inserted erroneously and shields the interior of the erroneous-insertion allowable space and a second shielding wall for shielding the wire withdrawal opening.

Connector having terminal accommodating chambers

An electronic component includes a circuit element, a circuit board that is connected to the circuit element, and a connection terminal that is connected to the circuit board. The connection terminal includes a main body, a spring member that is formed so as to be elastically deformable in two directions including a direction of moving closer to the circuit board disposed on the main body and a direction of moving away from the circuit board, and a pair of arm portions that is extended from the main body so as to position the spring member therebetween. The pair of arm portions passes through the circuit board, ends of the respective arm portions far from the main body are bent toward the spring member, and the circuit board is held between the ends and the spring member.

Electrical component

The present invention is to provide a connector seal allowing an accurate inspection of presence of an incorrectly formed bore in a terminal insertion bore of the connector seal. A connector seal includes a seal main body and a plurality of terminal insertion bores. Each terminal insertion bore has an upper membrane potion and a lower membrane portion, which are spaced one another and interconnected together with a lamella. Preferably, the terminal insertion bore has a membrane, which includes a substantially curved groove and a substantially curved lamella. Preferably, the terminal insertion bore has a membrane which includes a lamella, the lamella being oriented in a direction coincident with a diagonal line of a rectangular cross-section of a terminal so that corners of the terminal hit opposite ends of the lamella.

Connector seal

A multi-unit connector is formed by mounting a plurality of unit connectors, in which a terminal is received in a terminal receiving section of a housing, into a connector frame. The housing includes a front opening, and the connector frame includes a wall covering the front opening. The wall has a hole for terminal insertion, and a positioning rib projectingly. The terminal is positioned without rattling by supporting the terminal between the positioning rib and an inner wall at a side opposite to the positioning rib of the terminal receiving section. The positioning rib is provided with a slant surface for supporting the terminal. Furthermore, an additional positioning rib is arranged symmetrically against the positioning rib about a center of the hole and the slant surfaces for supporting a top end of the terminal are formed facing to each other at the positioning rib and the additional positioning rib.

Multi-unit connector

A connector for-use-on-board includes a bar-like terminal protruding from a connector housing. A forward end of the terminal is soldered to a printed circuit conductor of a board. A position-regulating hole is formed in such a way as to pass through a position in the vicinity of the forward end of the terminal in a direction perpendicular to an axial line of the terminal. A position-regulating protrusion protrudes from the connector housing and is loosely fitted into the position-regulating hole with a prescribed clearance.

Connector for use on board

An electronic circuit device consists of a connector provided with guide projections , a circuit board on which the connector is mounted, and a case provided with guide recesses . Since the guide recesses are broader in width at the end portions of the side walls of the case , and the guide projections are narrower in width at the side where the connector is first inserted, no high positional accuracy is required when the connector is received in the case. Both the guide recesses and the guide projections include inclined faces to form a V-shape.

Electronic circuit device

A connector with a holder prevented from coming-off is provided, whereby an unexpected breakaway of the holder can be securely prevented from occurring and an incomplete assembly of the holder with the connector housing can be securely detected. The connector with a holder prevented from coming-off includes: a connector housing a holder mounted on a surface of the connector housing a spacer inserted into the middle of the connector housing from a direction crossing at right angles with the mounting direction of the holder a locking member protrudingly formed to the holder a locking part for locking formed to the locking member and an engaging part for engaging with the locking part formed to the spacer wherein the engaging part engages with the locking part when the holder is completely mounted.

Connector with holder prevented from coming-off

In a waterproof connector M in which a waterproof seal member,is held between a connector housing,and a rear holder,and an electric wire seal portion closely attached to an outer periphery of an electric wire so as to seal between the electric wire and the connector housing,and a connector seal portion,B for sealing between both of the connector housings at a time of fitting to an opposing connector housing are integrally formed in the waterproof seal member,wherein the connector seal portion,B is provided on an outer peripheral surface of the rear holder,in an exposed manner so as to be closely attached to an inner periphery of a hood portion of the opposing connector housing at a time of fitting the connector housing,to the opposing connector housing.
