Description

Jig for insertion/extraction of connector}

The present invention relates to a jig, and more particularly, to a jig for inserting and extracting a connector.

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

The receptacle connector is mounted on a circuit board, and the pins of the receptacle connector are connected to contact points on the circuit board. The plug connector is coupled to the cable, and when the plug connector is coupled to the receptacle connector, the pins of the plug connector are connected to the pins of the receptacle connector, so that the cable and the circuit board are electrically connected.

Because the size of the plug connector is small, there is a problem in that it is difficult for workers to directly connect the plug connector to the receptacle connector. Additionally, when the plug connector is inserted into the receptacle connector, 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 a circuit board, there is a risk that not only the connector but also elements of the circuit board may be damaged.

The technical problem to be achieved by the present invention is to provide a jig that can easily insert and remove a plug connector from a receptacle connector.

The problem to be solved by the present invention is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

The present invention to solve the above technical problem is a jig for inserting and removing a connector used to pick up a first connector to which a cable is connected and insert it into or remove it from the second connector in the front and rear directions, with one side contacting each other. and a first body and a second body having a restoring force when the other side is tightened; and a first holder disposed on the first body and a second holder disposed on the second body, wherein the first holder and the second holder each have a receiving portion for accommodating at least a portion of the first connector. wherein the receiving portion includes at least a pair of first and second surfaces spaced apart in the front and rear directions, and at least a portion of the first surface and at least a portion of the second surface are located in the receiving portion. A jig for inserting and removing a connector is provided, which is disposed to overlap a portion of the first connector in the front and rear direction.

The accommodating part includes a first accommodating part in which a step 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 arranged, and the first accommodating part is a pair. It includes a first side (side 1a) and a second side (side 2a), and in a state where the stepped portion of the shield can is disposed within the first accommodating part, at least a portion of the first side is of the shield can. It may be disposed to overlap the front surface of the stepped portion, and at least a portion of the second surface 2a may be disposed to overlap the rear side of the stepped portion of the shield can.

The accommodating part further includes a third accommodating part disposed behind the second accommodating part and having a ring portion of a first connector surrounding the cable, and the third accommodating part has a pair of first surfaces (1b surfaces). and a second surface (2b surface), wherein in a state in which the ring portion of the first connector is disposed in the third receiving portion, at least a portion of the 1b surface is of the first connector surrounding 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 be disposed behind the third accommodating part and may further include a fourth accommodating part where the cable is placed.

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, The second part may include the first accommodating portion, and the third part may include the third accommodating portion.

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

The first body and the second body may be coupled to the first holder and the second holder, respectively, such 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. there is.

The first body and the first holder may be combined with each other or may be integrated with each other, and the second body and the second holder may be combined with or integrated with each other.

The first body and the second body may be combined with each other or may be integrated with each other.

The embodiment has the advantage of being able to easily insert and remove the first connector (plug connector) from the second connector (receptacle connector).

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

In the embodiment, the holder is configured to engage not only the shield can of the first connector but also the ring portion of the plug shell surrounding the cable, which has the advantage of increasing contact between the holder and the first connector.
