Description

Technical Field

[0001] The utility model relates to a cable connection in the technical field, in particular to a cable connector for connecting segmented cables. Background Art

[0002] In the fields of power, communication and industrial control, cables are important carriers of power and data transmission, and their connection quality is directly related to the operating efficiency and safety of the system. In order to effectively manage cables and facilitate maintenance and troubleshooting, cables are often divided into several sections. By segmenting, it is easier to find the problem and carry out targeted maintenance.

[0003] The traditional cable connection method is to directly twist the conductor wires inside the cable together, which may not ensure good contact between the cable conductors, resulting in increased contact resistance. In addition, in order to improve waterproofness and sealing, multiple layers of insulating tape are often wrapped around the cable joints, which is rather cumbersome. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Combined with Figure 1 A cable connector for connecting segmented cables comprises a connecting pipe 1, both sides of which are provided with threaded connectors 2.

[0024] Through the above structure, the cables on both sides are connected together by using the connecting pipe 1 and the connecting head 2, which is easy to operate.

[0025] Combined with Figure 2A sealing ring 3 is provided at one end of the connector 2 away from the connecting pipe 1. A through hole 4 is provided on the sealing ring 3. The sealing ring 3 is made of rubber and has a certain toughness.

[0026] Through the above structure, the connector 2 is respectively sleeved on the cables on both sides. Since the sealing ring 3 is made of rubber material and has a certain toughness, it can fit tightly on the cable through the through hole 4, and the overall sealing performance is good.

[0027] Combined with Figure 3 In order to play a certain insulating role, the inner wall of the connecting pipe 1 is provided with an insulating layer.

[0028] Embodiment 2

[0029] Combined with Figure 2 , Attachment Figure 3 and attached Figure 4 A fixing tube 5 is provided inside the connecting tube 1, and threaded clamping bolts 6 used with cables are inserted on both sides of the top of the fixing tube 5. Openings 7 are provided on both sides of the top of the connecting tube 1 and above the clamping bolts 6, and tightly fitting sealing plugs 8 are inserted in the openings 7.

[0030] Through the above structure, the cables on both sides are directly inserted into the fixing tube 5 and fit tightly together. The clamping bolt 6 is rotated and locked downward to fix the cables. The overall stability is strong. At the same time, the opening 7 and the sealing plug 8 are not only convenient for screwing the clamping bolt 6, but also have high sealing performance.

[0031] Combined with Figure 1 and attached Figure 3 The bottom end of the fixing tube 5 is provided with a support seat fixedly connected to the inner wall of the connecting tube 1, the cross section of the connecting tube 1 and the cross section of the fixing tube 5 are coaxial, and the cross section of the clamping bolt 6 and the cross section of the opening 7 are coaxial.

[0032] Through the above structure, the fixed tube 5 is fixed in the connecting tube 1 by means of the support seat, and the whole is stable. Moreover, the cross section of the connecting tube 1 and the cross section of the fixed tube 5 are coaxial, which is convenient for screwing them together. At the same time, the cross section of the clamping bolt 6 and the cross section of the opening 7 are coaxial, which is convenient for tightening the clamping bolt 6 through the opening 7.

[0033] When the utility model is implemented:

[0034] First, unscrew the connectors 2 on both sides, and respectively put them on the cables on both sides through the through holes 4, then unplug the two sealing plugs 8 on the connecting tube 1, and insert the cables at both ends into the fixing tube 5 from the connecting tube 1, so that the cables at both ends fit tightly together, and continuously screw the tightening bolts 6 through the openings 7 to tighten and fix the fitted cables. There is no need to screw the conductor wires together, and the cable conductors have good contact and low resistance.

[0035] When the compression is completed, the sealing plug 8 is inserted back into the opening 7, and then the connector 2 is moved and screwed on both sides of the connecting pipe 1 respectively. Moreover, since the sealing ring 3 is made of rubber material and has a certain toughness, it can fit tightly on the cable through the through hole 4, and the overall sealing is good.
