Abstract

(57) [Abstract] [Purpose] Prevents damage to the circuit when the connector is connected while the power is on by grounding the shield shell before contact between the terminals for signal transmission. To do. [Structure] The socket connector 1 is provided with an elastic contact piece 9 for grounding capable of contacting the shield shell 4 of the plug connector 3, and when the socket connector 1 is connected to the plug connector 3, the terminal 10 of the plug connector 3 is a socket. A connector in which the shielding shell 4 contacts the elastic contact piece 9 before contacting the terminal 6 of the connector 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a connector used for interface connection.

[0002]

2. Description of the Related Art In connection between units of electronic equipment, if a connector is connected while a switch is in an ON state, static current or overcurrent may flow between terminals to damage a circuit.

Therefore, generally, a metal shield shell is provided in the connector, and means is provided for bringing the shell into contact with each other and grounding the shell before the terminals are connected.

[0004]

However, in the conventional shield type connector, there is a possibility that the terminals may come into contact with each other when the connector is inserted due to a manufacturing error or an assembly error of parts. It was difficult to remove.

The present invention has been made by paying attention to such an actual situation, and provides a connector capable of surely grounding before contact between terminals even if there is a manufacturing error or an assembly error of parts. The purpose is to do.

[0006]

In order to achieve the above object, the connector of the present invention comprises a socket connector having an elastic contact piece for grounding capable of contacting a shield shell of the plug connector, and the socket connector having the plug connector. When the plug is connected, the shield shell is configured to contact the elastic contact piece before the terminal of the plug connector contacts the terminal of the socket connector.

[0007]

According to the structure of the present invention, since the elastic contact piece for grounding elastically contacts the shield shell of the plug connector, even if there is a manufacturing error or an assembly error in the parts, the contact between the terminals can be made. The elastic contact piece can be brought into contact with the shell before.

[0008]

1A, 1B and 1C show a procedure for connecting a shield connector according to the present invention.

This connector includes a socket connector 1 attached to a device body and a cord 2 derived from another device.
And a plug shell 3 made of metal, and a connecting shell of the plug connector 3 is provided with a metallic shield shell 4.

As shown in FIG. 2, the socket connector 1 is constructed by projecting a trapezoidal boss 7 in which a group of cylindrical terminals 6 are embedded in a resin-molded base plate 5, and both ends thereof are formed. Is equipped with a metal mounting member 8 that is grounded via an electric circuit on the device body side. Further, elastic contact pieces 9 made of a metal leaf spring material are provided at the boss 7 side portions of the respective attachment members 8.

This elastic contact piece 9 is, as shown in FIG.
It is provided with a connecting portion 9a that is fitted and connected to the lower surface of the mounting member 8 and a cantilever contact portion 9b with a curled tip, and when the plug connector 3 is inserted into the socket connector 1,
Before the terminal 10 of the plug connector 3 contacts the terminal 6 of the socket connector 1 as shown in FIG.
The tip of the cantilevered contact portion 9b is at the shield shell 4
, And then with the insertion of the plug connector 3,
As shown in FIG. 1 (c), the cantilever contact portion 9b is elastically retracted and deformed outward.

Although the elastic contact piece 9 of the embodiment can be attached to the attachment part provided in the conventional product, the socket connector 1 can be constructed by inserting it in advance on the base plate 5 side. It is also possible to provide the elastic contact pieces 9 in the front, rear, left and right to function as guides when the plug connector 3 is inserted. Further, the elastic contact piece 9 can be made of elastically deformable plastic material plated with metal, and the shape thereof can be set arbitrarily.

[0013]

As described above, according to the present invention,
Even if there is a manufacturing error or an assembly error of the parts, the elastic contact piece of the socket plug can be grounded by first contacting the shield shell of the plug connector when connecting the connector.
It is possible to make a highly reliable connector connection, which prevents static current or overcurrent from flowing between the terminals and damaging the circuit when the connector is connected while the switch is ON. Became.
