Description

Jigs for inserting and removing connectors

The present invention relates to a jig, and more particularly, to a jig for insertion and removal of a connector.

In various types of electronic devices (eg, wired/wireless communication devices, etc.), internal circuits are implemented on circuit boards. Connectors are used to connect circuit boards to other electronic devices or to other circuit boards. The connector may include a receptacle connector and a plug connector.

The receptacle connector is mounted on a circuit board, and pins of the receptacle connector are connected to contacts of the circuit board. And the plug connector is coupled to the cable, and when the plug connector is fastened to the receptacle connector, the pins of the plug connector are connected to the pins of the receptacle connector, and the cable and the circuit board are electrically connected.

Since the size of the plug connector is small, it is difficult for an operator to directly connect the plug connector to the receptacle connector. In addition, while the plug connector is inserted into the receptacle connector, there is a problem in that it is very difficult for an operator to grab the plug connector and remove it from the receptacle connector.

If the plug connector is forcibly inserted or removed while the receptacle connector is mounted on the circuit board, there is a risk that not only the connector but also the elements of the circuit board may be damaged.

An object of the present invention is to provide a jig capable of easily inserting and removing a plug connector into a receptacle connector.

Including, wherein the accommodating portion includes at least a pair of first and second surfaces spaced apart from each other in the front-rear direction, and at least a portion of the first surface and at least a portion of the second surface are located in the accommodating portion There is provided a jig for insertion and removal of a connector, characterized in that it is disposed to overlap with a partial region of the first connector in the front-rear direction.

The accommodating part includes a first accommodating part in which a stepped part formed in the shield can of the first connector is disposed, and a second accommodating part in which a cable located outside the shield can is disposed, and the first accommodating part is a pair of a first surface (surface 1a) and a second surface (surface 2a) of It may be arranged to overlap the front surface of the stepped portion, and at least a portion of the second a surface may be arranged to overlap the rear surface of the stepped portion of the shield can.

The accommodating part further includes a third accommodating part disposed behind the second accommodating part and in which a ring part of the first connector surrounding the cable is disposed, and the third accommodating part is a pair of first surfaces (first surface 1b). and a second surface (second b surface), wherein in a state in which the ring portion of the first connector is disposed in the third accommodating portion, at least a portion of the first b surface surrounds the outer surface of the cable. It may be arranged to overlap the front surface of the ring part, and at least a portion of the second b surface may be arranged to overlap the rear surface of the ring part.

The accommodating part may further include a fourth accommodating part disposed behind the third accommodating part and in which the cable is disposed.

The holder includes a first part coupled to the first body or the second body, a second part protruding forward from the first part, and a third part protruding downward from the second part, and The second part may include the first accommodating part, and the third part may include the third accommodating part.

The second part may include a lower surface connected to the first accommodating part and a front surface connected to the lower surface, and the lower surface may include a region inclined upward toward the front surface.

The first body and the second body may be characterized in that they are respectively coupled to the first holder and the second holder so that the longitudinal directions of the first body and the second body form an angle of 0° to 100° with respect to the horizontal plane. have.

The first body and the first holder may be coupled or integral with each other, and the second body and the second holder may be coupled with or integral with each other.

The first body and the second body may be coupled to each other or may be integral with each other.

The embodiment has the advantage that the first connector (plug connector) can be easily inserted and removed from the second connector (receptacle connector).

The embodiment has an advantage in that it is easy to insert the first connector into the holder because the holder enters and surrounds the first connector on both sides in the left and right directions perpendicular to the coupling direction of the first connector.

The embodiment has an advantage in that the holder is configured to engage not only the shield can of the first connector but also the ring part of the plug shell surrounding the cable, thereby increasing the contact between the holder and the first connector.
