Description

Connector structure

This creation relates to the field of connectors, and more particularly to a connector structure for inserting a cable.

The existing cable connector is inserted into the cable in the opening of the connector to insert the cable. However, when the cable is inserted into the connector, the cable may be pulled due to the cable, the conductive unit is loose, and fixed. Unstable resulting in poor signal transmission.

The existing cable fixed connectors are roughly divided into the following two forms:

1. A cover or pull cover locking device is added to the connector to strengthen the biting force between the terminal and the wire through the device, but the connector increases the assembly time in the manufacturing process and increases the processing steps.

2. Lock the cable through the terminal, design the shape of the terminal and increase the biting force between the terminal and the cable. However, this method makes the terminal more susceptible to damage due to stress and increases the difficulty of operation.

As described above, when the connector needs to be provided with the wire fixing device, since the fixed wire arranging device needs to be added, the connector processing process, the assembly cost and the time are relatively increased.

Accordingly, the author of the present author proposes an innovative connector structure to improve the above-mentioned conventional technical problems.

Based on the above purposes, the present invention provides a connector structure that can be inserted into a row of wires, including an insulative housing, a plurality of conductive terminals, a stop tab, and a housing. The insulating body has a top surface of the body and a bottom surface of the body opposite to the top surface of the body, a front wall of the body of the top surface of the adjacent body, and a rear wall of the body. The side of the top surface of the body adjacent to the front wall of the body is provided with at least one backing through the insulating body. And a plurality of terminal slots are disposed at intervals on a side of the top surface of the body adjacent to the rear wall of the body, and at least one of the plurality of terminal fixing holes is disposed at a side of the plurality of terminal slots. The plurality of conductive terminals are mounted in the terminal slot and are configured to be electrically connected to the cable. The stopping piece is disposed on the bottom surface of the body, and the upper surface of the stopping piece is provided with at least one stopping protrusion protruding through the stopping opening, and two stopping extensions extending obliquely downward, and the stopping extension comprises an elastic part and elasticity An extension portion and two unlocking portions projecting left and right on the stop piece. The housing is covered with an insulating body to form a cable space, the cable space has a cable opening for inserting the cable, and the side of the housing is provided with two unlocking openings for exposing the unlocking portion, wherein the cable has at least one fixing through the cable When the wire is inserted into the wire space, the front end of the wire abuts the protruding protrusion so that the stopping protrusion is pressed down, and the stopping protrusion protrudes forward with the wire to the fixed hole again.

Preferably, the side of the retaining projection that faces the direction in which the wire is inserted into the opening of the wire has a pressing bevel.

Preferably, the unlocking opening and the opening of the cable are open to the open space on the housing.

Preferably, the side of the retaining projection facing the direction in which the cable is pulled away from the opening of the cable has a fixing surface perpendicular to the edge of the fixed opening.

Preferably, the top surface of the insulative housing portion is recessed downwardly with respect to the side edge of the insulative housing to form a cable receiving space, and the terminal slot is disposed in the cable receiving space.

Preferably, the opening height of the unlocking opening and the end of the retaining extension are the same as the height difference of the retaining piece.

Preferably, the anti-retraction end portion of the top end abutting upward from one end of the elastic extension portion.

Preferably, the resilient extension abuts the top housing.

Preferably, the front wall of the body is provided with at least one front fixing opening of the casing, and the front fixing opening of the casing is provided to be compatible with at least one casing front fixing protrusion on the casing close to the lower edge of the casing.

Preferably, the rear wall of the body is provided with at least one rear fixing opening of the casing, and the rear fixing opening of the casing is disposed to insert at least one rear fixing protrusion of the casing extending from the upper edge of the casing at the rear side of the casing.

The connector structure of the present invention can have the following advantages:

(1) The terminal nip force is generated by the fixed opening and the retracting protrusion of the wire, and does not directly act on the wire and the conductive terminal, thereby reducing the difficulty of inserting the wire into the connector and avoiding damage of the conductive terminal.

(2) Through the setting of the retracting protrusion, the possibility that the cable is pulled out is reduced, and the wire can be smoothly unlocked by pressing the stopper piece without additionally providing the wire locking structure.
