Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a connector used in various electronic devices, and more particularly to a connector having a structure capable of surely and easily performing a circuit check.

[0002]

[Prior Art]

 Various electronic devices such as electronic calculators are composed of multiple devices such as a main controller and terminal devices, and these devices are often connected by wire cables. A connector is often used for the connection. FIG. 4 exemplifies a connector connecting portion between a device and a cable when a station line and a main device of a telephone exchange system or a main device and a relay box are connected by a cable. In FIG. 4, (1) is a circuit board inside the device, (2) is a connector (receptacle) fixed to the circuit board (1), and (3) is a connector (receptacle) fitted to the receptacle (2). Plugs) and (4) are cables connected to the plugs. 5 (a) and 5 (b) show the plug (3) in FIG. 4, particularly FIG. 5 (a) shows the appearance of the plug, and FIG. 5 (b) shows A in FIG. 5 (a). FIG. In FIGS. 5A and 5B, (31) is a body made of an insulating material such as plastic, and the body (31) is composed of a base portion (311) and a fitting portion (312). Reference numeral (32) is a cover made of an insulating material, for example, plastic, like the body (31). The cover (32) receives the cable insertion hole (321) and the connection portion (332) of the contact (33). A housing hole (322) is provided. Reference numeral (331) is a contact portion of the contact (33), which is a portion which comes into contact with the contact of the receptacle (2) when fitted to the receptacle (2).

[0003]

[Problems to be solved by the device]

 In the conventional connector of this type shown in FIGS. 4 and 5 (b), the circuit check cannot be performed in the fitted state of the plug and the receptacle, that is, in the operating state due to its structure. Therefore, a plug having the appearance shown in FIG. 6 has been proposed as a device that enables circuit check even when the plug is fitted in the receptacle. That is, as shown in the cross-sectional view of FIG. 7 showing the BB section in FIG. 6, the accommodation hole (322) of the contact (33) provided in the cover (32) of the plug (3) is covered with the cover (32). ) Is a through hole penetrating outward from the surface of the above) and is used as a circuit check hole (7). According to this structure, the check can be performed by inserting the check pin (8) from the circuit check hole (7). However, even if the circuit check hole (7) is provided as shown in FIGS. 6 and 7, the circuit check hole (7) is on the upper surface of the cover (32) as described above. Therefore, as shown in FIG. 4, in the case of so-called high-density mounting in which the distance between the circuit boards (1) is narrow, the connectors attached to the adjacent circuit boards interfere with each other and the circuit check pins ( It is not easy to insert 8) and it is difficult to make a reliable check.

[0004]

[The purpose of the device]

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector capable of surely and easily performing a circuit check.

[0005]

[Means of the Invention for Solving the Problems]

 The above object can be achieved by a very simple means of providing a groove for inserting a circuit check pin which is parallel to an insertion hole of a cable connected to a plug and reaches a contact attached to the plug.

[0006]

[Action]

 Since the circuit check pin can be inserted straight from the same direction as the inserted cable, the presence of the connector mounted on the adjacent board has almost no effect on the insertion of the circuit check pin.

[0007]

【Example】

 Hereinafter, a connector according to the present invention will be described with reference to the drawings. FIG. 1 shows an appearance of a specific example of a plug (3) of a connector according to the present invention. In FIG. 1, (31) is a body made of an insulating material, for example, plastic, and this body is (31) is composed of a base portion (311) and a fitting portion (312). Like the body (31), (32) is a cover made of an insulating material such as plastic, and this cover (32) is provided with a check groove (7) into which a circuit check pin (8) can be inserted. Has been. FIG. 2 shows the sectional structure of the plug (3) shown in FIG. 1, and also shows the sectional structure of the receptacle (2) fitted with the plug (3). FIG. 2 shows the sectional structure of the plug (3) shown in FIG. 1, and also shows the sectional structure of the receptacle (2) fitted with the plug (3). In FIG. 2, (1) is a circuit board, and (2) is a receptacle mounted on the circuit board (1). The receptacle (2) is made of an insulating material such as a plastic body (21) and contacts (22), and the body (21) has a box shape as a whole and has an opening (211) for receiving the plug (3). However, the receiving hole (212) of the projection (313) provided in the fitting portion (312) of the plug (3) is provided. (3) is a plug. This plug (3) is almost the same as the conventional one as a whole, and is composed of a body (31) and a cover (32), and the body (31) is a base part. (311) and the fitting portion (312), and the socket contact (33) is attached inside thereof. The fitting portion (312) of the body (31) is provided with a protrusion (313), and when the fitting portion (312) is inserted into the opening (211) of the receptacle (2), the protrusion (313) becomes a receptacle. It falls into the receiving hole (212) of (2) and stabilizes the fitting. On the bottom surface of the cover (32) of the plug (3), there is provided a check groove (323) forming a hole for inserting a check pin in parallel with the insertion hole (321) of the cable (4). The groove (323) has a size such that the check pin 8 of the circuit checker (not shown) can be inserted, and when the cover (32) is fitted in the body (31), the check pin (8) is ) Has a length reaching the contact (33) mounted in the body (31).
