The module connector can accommodate a miniaturized module such as a camera module and reliably fix the module in an electrically connected state, and make the connector itself in lower profile. With this connector (), a housing () has a concave container () that accommodates an inserted camera module () in which a plurality of pads are disposed its bottom face. A contact () has: an arm () that projects from the bottom face of the container () to the interior of the container () and that elastically deforms; and, at the tip of the arm (), a contact point part () that is swingable in the insertion direction of the camera module () by means of elastic deformation of the arm () and that contacts a pad. A shield cover () is attached to the housing () detachably covering the accommodating part () and abuts on an upper face () of the camera module () urged in a direction opposite to the insertion direction by the arms () of the contacts (), to sandwich the camera module () in combination with the contacts ().

A memory card connector is able to insert and remove a memory card () without leaving marks of insertion and removal on the memory card (), prevent the memory card from popping out when the memory card is inserted and removed and enable miniaturization at ease with a simple configuration. In this connector (), by the side of a container () in which the memory card () is inserted, a slider () that has a lock claw part () engaging with a notch part () formed on the side of the memory card () is arranged movable in the longitudinal direction and swingable in a location at a card insertion slot end which is a location the memory card () is inserted halfway. The slider () is urged in the direction of removal by a coil spring (), and this urge is suppressed by a slider pressuring piece () which presses the slider () from above and claw pressing piece () that presses the slider () located in a location at the card insertion slot end toward the memory card ().

Provided is a connector for connecting an electronic component, which reduces noise radiation when the electronic component is connected to a substrate through the connector and driven. In a connector (), a connector main body () stores a module () inside an opening section (), and the connector main body is mounted on the substrate by being electrically connected to the stored module (). The connector main body () is provided with a contact lead section () which is lead out to the side of the connector main body () to be bonded to a conductor on the substrate. A cover member () which opens and closes by turning with a shaft section () at the center is pivotally supported on the connector main body (), and the opening section () is covered with the cover member () from above. The cover member () is provided with a conductive skirt section () for covering the contact lead section () from above in a closed state.

Connector for connecting electronic component

A module connector reliably locks a module such as a camera module, which is accommodated, to prevent the module from falling and make a module connector in lower profile. This module connector has contact pins () that electrically connect with the module inside a container () in which the camera module is inserted. Retaining members () are provided in sides of the container (), elastically deform when the module is inserted such that claw parts (), which form the tip parts of arm parts () projecting toward the container (), move to the sides of the container (), and engage with an engaged part () of the camera module accommodated in the container (). An arm part () connects with an upper end part of a second body part () bent from the tip of a first body part (), which projects toward the container () in the side of the container (), in the direction going away from the container () and extends upward.

Electric connector

A connection terminal that can be brought into stable one-point contact with an electrode and that allows for a smooth connecting operation, even in the case of small contact pads or other such electrodes for establishing electrical contact. A socket contact as the connection terminal is provided to an electronic-component connector having an open portion into which a module is inserted. The socket contact comes into contact at the distal end with an electrode of the module in a direction that intersects with the connecting direction of the module when the module is inserted. The socket contact has a contact part having a contact trunk that protrudes into the opening from the proximal-end side, and a contact point provided to the distal end of the contact trunk. The concave electrode of the module slides from the proximal-end side of the contact part to the distal-end side, and the contact part narrows towards the front surface.

A positive terminalfor a dry battery of a battery boxincludes an electrode portionadapted to make contact with the anode of a battery, a soldering portionsoldered to the substrate, and a lead portionintegrally provided between the electrode portionand the soldering portion. Further, a load absorbing means is provided in the lead portionto prevent a force exerted in the longitudinal direction of the battery from being applied directly to the soldering portion. The lead portionincludes an extending partwhich extends in the longitudinal direction of the battery and is continuous with the electrode portion, and a loop partbent in a substantially ring shape and positioned within a plane roughly perpendicular to the longitudinal direction of the battery, wherein the loop partforms the load absorbing means. According to the positive terminal described above, it is possible to prevent a damage of the substrate due to vibration or shock and to reduce a manufacturing cost of a battery box equipped with the positive terminal.

An electronic-component connector forms a secure detachable connection and is packaged in a small space even when the electronic component is a module that is linked to an optical waveguide, and transmits and receives a signal such as an optical signal via the transfer member. An optical waveguide extends from a first side of a module connected to the connector. The connector body of the electronic-component connector has an open portion for accommodating a module inserted from the open side. A socket contact portion for contacting a connection terminal of the module is provided to the open portion. A lead-out path is formed in the shape of a groove in the connector body communicated with the open portion, and leads out the optical waveguide from the connector body. A cover member is attached to the connector body so as to open, close, and secure the module inside the open portion.
