Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically to a cable connector in which the cable length is fixed but can be changed. Background Technology

[0002] Currently, cables are widely used in the electrical industry. The main function of cable connectors is to ensure smooth circuit flow, maintain cable sealing, and guarantee the insulation level at the cable joint, ensuring safe and reliable operation. Existing technology, such as Chinese patent application number 2015200778978, discloses a waterproof connector, which includes a connector body, a fastening ring, a washer, a sealing ring, and a nut. The fastening ring and nut are threaded to both ends of the connector body, the washer is located between the connector body and the fastening ring, and the sealing ring is located within the connector body. When this technology is used, the fastening ring is removed and the cable is passed through the connector body. Then, the part of the connector body without the fastening ring is fixedly connected to the corresponding equipment. The part of the cable inside the connector body remains straight, and the part of the cable outside the nut can be bent relative to the end face of the nut. However, the existing technology has a drawback: the length of the cable that remains straight is proportional to the length of the connector body. Depending on different installation environments, the length of the cable that remains straight needs to be changed. Therefore, the existing technology can only adapt to different installation environments by producing and installing waterproof connectors of different specifications, which has a limited scope of application and increases the user's operating costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable connector with variable fixed cable length, wide applicability and reduced usage cost.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cable connector with a fixed variable length, comprising a connector body and a nut screwed to one end of the connector body. An auxiliary piece extending along the length direction of the connector body is provided on the end face of the nut away from the connector body. A pair of wire-passing holes are provided on the auxiliary piece. By passing one end of the wire through the two wire-passing holes in succession and wrapping it around the outside of the cable, the cable is fixed together with the auxiliary piece.

[0005] As a further improvement of this utility model, the threading holes are in multiple pairs and distributed along the length direction of the auxiliary piece.

[0006] As a further improvement of this utility model, the cross-sectional profile of the auxiliary piece is arc-shaped and coaxial with the nut, and the paired threading holes are located on the same circumference.

[0007] As a further improvement of this utility model, the outer contour diameter of the auxiliary piece is smaller than the diameter of the circumference of the outer contour of the nut, and anti-scratch blocks are provided on the outer wall of the auxiliary piece at both ends of the paired threading holes.

[0008] The beneficial effects of this utility model are as follows: by passing one end of the wire through two wire holes and wrapping it around the outside of the cable, the cable and the auxiliary piece are fixed together. Compared with the prior art, this design can adjust the fixed length of the cable without replacing the cable connector, which improves the applicability of the cable connector and reduces the cost of use.

[0010] Reference numerals: 1. Connector body; 2. Nut; 3. Auxiliary piece; 4. Wire hole; 5. Anti-scratch block. Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0012] Reference Figure 1 As shown, a cable connector with a variable fixed length for a cable in this embodiment includes a connector body 1 and a nut 2 screwed to one end of the connector body 1.

[0013] Based on the aforementioned existing technology, an auxiliary piece 3 is integrally formed on one end face of the nut 2 through injection molding process. The length direction of the auxiliary piece 3 is parallel to the axis of the nut 2. The auxiliary piece 3 has a pair of wire holes 4, and the two wire holes 4 are distributed along the width direction of the auxiliary piece 3.

[0014] During use, one end of the wire is passed through one of the wire holes 4 from the outside of the auxiliary piece 3 to the inside of the auxiliary piece 3. Then, the wire is wrapped around the cable. Next, the end of the wire is passed through another wire hole 4 from the inside of the auxiliary piece 3 to the outside of the auxiliary piece 3. Finally, the two ends of the wire are tightened and knotted together. The part of the cable wrapped by the wire is in contact with the inner wall of the auxiliary piece 3 under the action of the wire. The knotted part of the wire is in contact with the part of the auxiliary piece 3 located between the two wire holes 4. The length of the cable that is fixed is increased from the original length of the connector body 1 to the length between one end of the connector body 1 and the wire. The length of the cable that is fixed can be adjusted by moving the wire along the length direction of the wire hole 4. Alternatively, the wire can be untied and pulled out so that the length of the cable that is fixed is restored to the same length as the connector body 1.

[0015] Compared to existing technologies, this design allows for the adjustment of the fixed cable length without replacing the cable connector, thus increasing the applicability of the cable connector and reducing usage costs.

[0016] As one specific implementation method of the improvement, refer to Figure 1As shown, there are multiple pairs of wire holes 4 distributed along the length of the auxiliary piece 3. This design further increases the range of variation in the fixed length of the cable, and can change the adjustment of the fixed length of the cable from a slight change to a gradual change, making it easier to adjust the fixed length of the cable to suit different environments.

[0017] As one specific implementation method of the improvement, refer to Figure 1 As shown, the auxiliary piece 3 is an arc-shaped piece and is coaxially arranged with the nut 2. The pair of thread holes 4 are located on the circumference of the arc-shaped outline of the auxiliary piece 3. Compared with making the auxiliary piece 3 flat, this design can improve the bending resistance of the auxiliary piece 3 and the connection stability between it and the nut 2.

[0018] Further optimization involves machining grooves into the outer wall of the auxiliary piece 3 during the processing of the auxiliary piece 3. The bottom of the groove is arc-shaped, which is the outer wall of the auxiliary piece 3. The groove walls at both ends of the groove are anti-scratch blocks 5. Pairs of wire-passing holes 4 are machined on the bottom of each groove. The two ends of the wire-passing holes 4 extend to the adjacent anti-scratch blocks 5. This design can accommodate the knot of the wire in the groove, preventing external objects or solid particles carried by the wind from scratching the knot of the wire and causing the wire to break or loosen. This ensures the stability of the wire tie and indirectly improves the stability of the cable being fixed.

[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
