Description

Firmly-connected cable connector Technical Field The utility model belongs to the technical field of cable joints, and particularly relates to a firmly connected cable joint. Background The cable connector is an important element for connection between adjacent cables, and contacts the cables through a contact piece arranged inside the sheath, so that the adjacent cables are connected. However, the contact area of the inner contact piece of the existing cable connector is relatively small, and when the cable connector is subjected to external action to generate torsion and deflection, gaps are formed between the contact pieces which are originally in close contact with the inner part of the connector to cause poor contact, so that the existing cable connector is difficult to stably and safely ensure that the cable is in a communication state under the condition of torsion and deflection. Therefore, the utility model discloses a cable joint which is firmly connected, aiming at the technical problems existing in the prior cable joint. Disclosure of utility model The utility model discloses a firmly connected cable connector, which can still ensure the firm connection between cables under the condition that the connector is twisted and swung. The utility model is realized by the following technical scheme: The cable connector comprises a first connector and a second connector which are in butt joint, wherein a convex contact piece is arranged in the first connector, a concave contact piece is arranged in the second connector, the convex contact piece and the concave contact piece are correspondingly inserted, one end, far away from the concave contact piece, of the convex contact piece is provided with a cable connecting contact piece, and one side, far away from the convex contact piece, of the concave contact piece is provided with a compression ring for axially compressing the cable connecting contact piece. One end that the first joint kept away from the second joint is used for penetrating the cable, and one end that the second joint kept away from the first joint is used for penetrating the cable. The cable core is wound on the cable connecting contact piece, the cable connecting contact piece is slidably arranged in the first connector or the second connector, then the compression ring is arranged in the first connector or the second connector, and the cable connecting contact piece is axially compressed through the compression ring, so that the cable connecting contact piece is in close contact with the convex contact piece or the concave contact piece. And then the first connector is in butt joint with the second connector, so that the convex contact piece is in split contact with the concave contact piece, and the connection of the cable is realized. The connecting area is increased through the convex contact piece and the concave contact piece, and even if the cable joint part is subjected to deflection movement, the convex contact piece and the concave contact piece can be ensured to be always in contact connection with partial areas, so that the stable connection of the cable is ensured.
