In order to form a continuous path for the circuit or to connect the circuit to some electrical products, a connection point is needed between different lines to electrically connect the different lines, and a cable connector is used to electrically connect the different lines. In order to ensure the stable connection of the cable joint, a fixing tool is installed on the cable joint, so that the stable connection of the cable joint is realized.

However, the fixing tool applied at present has the technical problem of unstable fastening.

In view of this, the embodiment of the present invention provides a cable connector fixing device, which can fix a cable connector more stably compared to other fixing tools.

In order to better understand the technical scheme, the technical scheme is described in detail with reference to the attached drawings.

Referring to fig. 1, an embodiment of the present invention provides a cable joint fixing device, which includes:

a pressing plate 100 for abutting against one side of the cable connector 500, a limiting member 110 for limiting the position of the connecting portion 510 is disposed on one side of the pressing plate 100 close to the cable connector 500,

and the elastic member 300 connects the pressing plate 100 and the wire holder 200 so that the pressing plate 100 and the wire holder 200 cooperate to clamp the cable connector 500.

In the solution adopted in this embodiment, when the pressure plate 100 is used to fasten the cable connector 500, the pressure plate 100 abuts against the cable connector 500. When the cable connector fixing device is installed on the cable connector 500, the position of the connecting portion 510 is limited by the limiting member 110 on the pressing plate 100, so that the cable connector 500 is limited, and the technical problem that the fixing tool is unstable in fastening when the cable connector 500 is fixed is solved. The wire holder 200 is disposed on a side of the cable connector 500 away from the pressing plate 100, and one end of the cable connector 500 is inserted into the wire holder 200 to electrically connect the cable connector 500 to an electrical product.

Specifically, the cable connector 500 includes a connection portion 510, and the connection portion 510 is disposed at one end of the cable connector 500 and is mainly used to assist the operation of the cable connector 500. The connecting portion 510 has two inclined surfaces connected by a horizontal plane, and the three inclined surfaces may form three sides of an isosceles trapezoid in a side view direction, as shown in fig. 3. The connecting portion 510 is provided with a through hole, and when the connecting portion 510 needs to be detached, a rod-shaped object can be inserted through the through hole of the connecting portion 510, and the cable connector 500 can be separated from the wire holder 200 by applying force to the rod-shaped object.

The limiting member 110 may or may not abut the cable joint 500. When the limiting member 110 abuts against the cable joint 500, the contact area between the pressing plate 100 and the cable joint 500 can be increased, so that the stress is balanced. Further, when the stopper 110 abuts against the cable connector 500, the pressing plate 100 does not swing following the swing of the connecting portion 510, and the stability of the pressing plate 100 is improved.
