There is disclosed a connector in which there is no need to provide any separate or additional retaining arm, and a detection member (33) can be provisionally retained, and the construction of the connector is simplified, and the detection member is prevented from being lost. A fitting hole (31) in communication with a refuge space 29 for a terminal retaining piece portion (27) is formed in a connector housing, and is open to a front end face thereof. There is provided the detection member for being inserted into the fitting hole, and the detection member has an insertion plate (35a, 35b) for being inserted into the refuge space. The insertion plate has an insertion guide surface (43) for guiding the insertion of a mating connector terminal, (53) and a cantilever-like, elastic retaining arm, (45) having the guide surface at its free end, is formed at the insertion plate. A provisionally-retaining convex portion (41) is formed on the connector housing, and a provisionally-retaining projection (39) is formed on the insertion plate. In a retracted condition of the detection member in which the insertion plate is disposed out of the refuge space, the provisionally-retaining projection is retainingly engaged with the provisionally-retaining convex portion, thereby preventing the detection member from being withdrawn from the fitting hole.

Connector including a terminal insertion detecting member

A construction of a rear holder for a connector capable to be drawn out that comprises a connector housing, connector terminals and a rear holder accompanied with a means for pulling the rear holder out, the rear holder as a stopper for movement of the terminals being inserted into the housing from a opening behind and engaging with the housing by means of projections on the holder and holes in the upper wall of the housing, is characterised by a channel with a pit at the front bottom forming a supporter step for the means, which the means for pulling the rear holder out is easily inserted into.

Construction of rear holder for connector capable to be drawn out

An improved connector terminal is provided that is capable of being inserted more easily into a terminal accommodating chamber of a connector housing. The connector terminal comprises a wire connecting part and an electric contact part that may be inserted into the terminal accommodating chamber of a connector housing having an opening edge. The electric contact part includes a rectangular cylindrical body having two pairs of opposing walls for a total of four walls and a guide protrusion protruding continually from the tip of at least one of the four walls of the body. The guide protrusion has a guide surface that slides along the opening edge of the connector housing when the electric contact part is inserted into the terminal accommodating chamber. The guide protrusion is structured to protrude from one of the four walls so as to have substantially the same width as the wall width or structured so that a bent guide surface is formed by extending and bending tips of at least two of the four walls that have a width smaller than the width of the respective wall.

Connector terminal

A pair of threaded-connection type connectors in which male and female connectors are mutually coupled to each other by engagement of a bolt provided in the male connector and a nut provided in the female connector, comprises a cylindrical sleeve extending from the male connector in a direction opposite to a connecting portion with the female connector, and a grommet for watersealingly covering the male connector except for the connecting portion thereof. The grommet includes an opening tightly fitted an outer cylindrical surface of the sleeve so that the bolt can be rotated without removing the grommet from the male connector and the grommet can define the waterproofed space therein together with the sleeve.
