Description

  The present invention relates to a connector cap mounted on a terminal such as an electronic device, particularly a portable electronic device.

  Terminals such as electronic devices, particularly portable electronic devices, are equipped with connectors for connection with other electronic devices or for adjustment, and are not always used. A protective cap is attached.

  FIG. 6 shows a state in which a casing of a conventional electronic device is omitted and the inside is exposed. In FIG. 6, 1 is a chassis, 2 is a wiring board fixed to the chassis 1, and 3 is the wiring board. 2 shows a shield cover attached.

  A connector 4 is mounted on the end of the wiring board 2 for connection with other electronic devices or for adjustment.

  In a terminal such as a portable electronic device, since the connector 4 is not always used, a connector cap 5 is usually attached to the connector 4 to protect the connector 4.

  A conventional connector cap 5 will be described with reference to FIG.

  FIG. 7 is a view from the back side of the connector cap 5. The connector cap 5 is made of high-elasticity synthetic resin, and includes a cover portion 6 that covers the entire connector 4 and a fitting portion 7 that fits into a concave portion of the connector 4, the chassis 1 or the housing. Locking projections 8 and 9 are provided so as to be fitted into the attachment holes (not shown). Reference numeral 11 denotes a locking piece that engages with an engagement recess (not shown) of the connector 1.

  The locking projections 8 and 9 have heads 8a and 9a larger than the engagement holes of the chassis 1 and the casing, respectively. By pushing the locking projections 8 and 9 into the engagement holes, the heads 8a and 9a shrink due to elastic deformation, pass through the engagement holes, and are restored. The fitting state between the portions 8 and 9 and the engaging hole is maintained.

  In the connector cap 5, the holding force of the connector cap 5 depends only on the fitting force between the locking projections 8 and 9 and the engagement holes, and the locking projections 8 and 9 and the engagement holes If the elastic force is reduced due to deterioration of the connector cap 5 over time, or if an electronic device is dropped or shocked or vibrated, etc. The connector cap 5 may fall off.

  For this reason, as shown in FIG. 8, a connector cap retainer 12 is extended from the casing or the shield cover 3, and the tip end portion 12a of the connector cap retainer 12 is bent, and the connector portion is bent by the tip end portion 12a. There is something that prevents the cap 5 from being pulled out.

  However, when the connector cap presser 12 is provided to prevent the connector cap 5 from falling off, the distal end portion 12a is bent after the connector cap 5 is mounted, and the last work process is performed. Usually, the work is performed in a narrow place where the work position cannot be visually checked, and there is a problem in workability and reliability.

Since it is configured to prevent removal, the connector cap securely covers the connector, and the connector cap is prevented from falling off even when impact or vibration is applied due to the electronic device dropping etc. To do.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is an external perspective view of an electronic device 14 according to the present invention, FIG. 2 is a perspective view showing a state in which a connector cap is removed, and FIG. 3 is a part of a casing 15 of the electronic device 14 removed. It is the perspective view which exposed the inside. In FIG. 1 to FIG. 3, the same components as those shown in FIG. 6 and FIG.

  A wiring board 2 is housed inside the electronic device 14, and a connector 4 and a connector 24 (not shown) are mounted on the wiring board 2, and the connector 4 is exposed on the side surface of the housing 15, The other connector 24 is exposed on the bottom surface.

  A cap housing recess 16 is formed on the side surface of the housing 15, and an opening 17 is formed at the bottom of the cap housing recess 16 to expose the end surface of the connector 4. Stop holes 18 and 19 are formed. A connector cap 20 shown in FIG. 4 is fitted into the cap housing recess 16. Similarly, a cap housing portion recess (not shown) is also formed on the bottom surface, and the connector cap 30 shown in FIG. 5 is fitted into the cap housing portion.

  The connector cap 20 includes a cover portion 6 that fits into the cap housing recess 16, a fitting portion 7 that protrudes substantially at the center of the cover portion 6, and both end portions of the cover portion 6 that sandwich the fitting portion 7. The locking projections 8 and 9 have locking pieces 11 and 11 on both sides of the fitting portion 7. A groove 25 is formed in the width direction on the surface of the connector cap 20. The groove 25 functions as a hinge and can be bent at the groove 25 portion.

  The locking projections 8 and 9 are formed with heads 8a and 9a larger than the locking holes 18 and 19, with the head 8a having a trapezoidal shape and the head 9a having a conical shape.

  A key hole 21 passes through the head 8 a, and a lock key 22 can be inserted into and removed from the key hole 21.

  A case where the connector cap 20 is attached will be described.
