Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and in particular to a cable connector. Background Technology

[0002] In the process of power or signal transmission, connectors are often used to connect different cables to ensure stable transmission of current or signals. These connectors typically have a housing to protect the internal conductive components, preventing them from being directly exposed to the environment. Simultaneously, they connect the conductive wires of different cables through these conductive components, enabling normal current conduction and meeting the cable connection needs in various scenarios.

[0003] Existing cable connectors have several problems in practical use. The sealing effect between the housing and the cable is often not ideal, allowing external dust and moisture to easily enter through the gaps between the housing and the cable, affecting the working condition of conductive components and even causing conductive failures. Moreover, when the cable's conductive wires are connected to conductive components, improper fixing can easily cause displacement, reducing the contact area between the conductive wires and the conductive components and affecting the conductivity. Therefore, a new cable connector is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the conductive wires of cables are prone to displacement due to improper fixing when connected to conductive components, resulting in a reduced contact area between the conductive wires and the conductive components and affecting the conductivity. Therefore, this invention proposes a cable connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cable connector includes a housing consisting of an upper shell and a lower shell, and a conductive block disposed inside the housing. A through connection hole is provided between the two sides of the conductive block for connecting branch wires, and an open main wire hole is provided on one side of the conductive block for connecting the main wire. Two pairs of clamping bolts are threaded to the top of the conductive block, and the two pairs of clamping bolts pass through the conductive block and are respectively located in the connection hole and the main wire hole. An L-shaped limiting piece is inserted into the top of the conductive block. The limiting piece extends into the main wire hole to limit the main wire. A threaded post is fixedly connected to the top of the conductive block. The threaded post passes through the limiting piece. A nut is threadedly connected to the top of the threaded post to clamp the limiting piece.

[0006] As a further embodiment of this utility model, the upper shell and the lower shell are integrally formed with fixed edges around their close proximity, and the fixed edges are fixed together by bolts.

[0007] As a further improvement of this invention, a sealing gasket is provided between the two fixed sides to keep the housing sealed.

[0008] As a further embodiment of this utility model, two through holes are provided at both ends of the upper shell and the lower shell for the cable to pass through, and the through holes correspond to the connection hole and the main wire hole.

[0009] As a further embodiment of this utility model, an arc-shaped threading shell is fixed to one side of each perforation, and multiple arc-shaped sealing sheets are adhered to the inner wall of the threading shell. The multiple sealing sheets are adhered to each other and can be separated by pulling.

[0010] As a further embodiment of this utility model, both sides of the upper and lower shells are fixed with horizontal plates, and the surfaces of the horizontal plates are threaded with through screws. On the opposite side of the screws, arc-shaped clamps are rotatably connected.

[0011] As a further improvement of this invention, rubber pads are adhered to the opposite sides of the clips.

[0012] As a further embodiment of this invention, the conductive block is made of copper.

[0013] In this application, during use, the main cable is exposed by breaking the insulation to expose the conductive wire. The conductive wire is then placed in the main cable hole, and a limiting plate is inserted into the conductive block. The nut is then tightened to fix the limiting plate and limit the conductive wire. When the clamping bolt on the main cable hole is tightened, the conductive wire remains stable, preventing it from shifting or coming out of the main cable hole due to compression. This increases the contact area between the conductive wire and the conductive block, improving conductivity. Then, the conductive wire from the branch cable is inserted into the connecting hole and fixed by the clamping bolt above it. Next, depending on the cable thickness, part of the sealing plate is peeled off. The upper and lower shells are then merged and fixed with bolts. The sealing plate clamps the cable and provides good waterproofing. Finally, the screw is tightened, causing the clamping plate to move and hold the cable in place, preventing separation due to external drag and increasing cable stability.

[0014] Beneficial effects: In this utility model, the cable connector, through the combined use of limiting plates, threaded posts and nuts, as well as clamping bolts, screws of the cross plate, clamping plates and rubber pads, can prevent the main conductive wire from being squeezed out, increase the contact area between the conductive wire and the conductive block, fix the main wire and the branch conductive wire, clamp the cable to avoid separation caused by external force dragging, reduce connection failures, and improve the fixation and conductivity of the cable connection; In this utility model, the cable connector, through the cooperation of the fixed edges of the upper and lower shells, the sealing gaskets, and the sealing sheet of the cable threading shell, can prevent external dust and moisture from entering the interior of the shell, while clamping the cable to prevent impurities from affecting internal components such as the conductive block, ensuring that the conductive process is not affected by the external environment, achieving good sealing and waterproof performance and protecting the stable operation of internal components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one embodiment: Refer to Figures 1-3 A cable connector is disclosed, comprising a housing 1 and a conductive block 8. The housing 1 is divided into an upper housing and a lower housing, both of which have integrally formed fixing edges 2 around their adjacent areas. The fixing edges 2 are fixed together by bolts. A sealing gasket 9 is also provided between the two fixing edges 2. When the fixing edges 2 are tightened by the bolts, the sealing gasket 9 can fit tightly between the two fixing edges 2, thereby maintaining the sealing state inside the housing 1 and preventing external dust, moisture, and other impurities from entering the housing 1 and affecting the normal operation of the components. Two through holes are provided at both ends of the upper and lower housings. These through holes are used to guide the cable through, and the positions of the through holes correspond one-to-one with the connection holes 10 and main wire holes 11 on the conductive block 8, ensuring that the cable can be accurately connected to the conductive block 8 after passing through the through holes. Each perforation has an arc-shaped cable housing 6 fixed on one side. Multiple arc-shaped sealing sheets 7 are bonded to the inner wall of the cable housing 6. The multiple sealing sheets 7 are bonded to each other and can be separated by pulling. Subsequently, some sealing sheets 7 can be peeled off according to the thickness of the cable, so that the remaining sealing sheets 7 can fit against the outer wall of the cable.

[0019] Specifically, the wiring shell 6 is fixedly connected by welding.

[0020] A conductive block 8 is disposed inside the housing 1. The conductive block 8 is made of copper, which has good conductivity and can effectively reduce losses during current transmission, ensuring conductivity stability. A through-hole 10 is formed between the two sides of the conductive block 8 for connecting the conductive wires of the branch lines. An open main wire hole 11 is formed on one side of the conductive block 8, such as... Figure 3 As shown, the right side of the main wire hole 11 is open, and the main wire hole 11 is used to connect the conductive wire of the main wire. In use, first, the main wire is exposed by breaking the insulation, and then this part of the conductive wire is placed in the main wire hole 11. Then, the L-shaped limiting piece 12 is inserted into the top of the conductive block 8. The top of the conductive block 8 is provided with a hole for the limiting piece 12 to be inserted. The hole is through the main wire hole 11, so that the limiting piece 12 will extend into the main wire hole 11, which just forms a limit on the conductive wire in the main wire hole 11. A threaded post 13 is also fixedly connected to the top of the conductive block 8. The threaded post 13 is formed by welding or as part of the conductive block 8. The threaded post 13 passes through the limiting plate 12. A nut 14 is threadedly connected to the top of the threaded post 13. After the nut 14 is tightened, the limiting plate 12 can be tightly clamped to the top of the conductive block 8, ensuring the limiting effect of the limiting plate 12 on the main conductive wire. This prevents the main conductive wire from being squeezed out of the main wire hole 11 when the clamping bolt 15 is tightened later. At the same time, it can increase the contact area between the conductive wire and the conductive block 8, further improving the conductivity.

[0021] In another embodiment: Reference Figures 1-3 A type of cable connector.

[0022] The top of the conductive block 8 is threaded with two pairs of clamping bolts 15. After passing through the conductive block 8, one pair of clamping bolts 15 is located in the connecting hole 10, and the other pair is located in the main wire hole 11. After the main conductive wire is limited by the limiting piece 12, the clamping bolts 15 in the main wire hole 11 are tightened to fix the main conductive wire in the main wire hole 11. Then, the conductive wire in the branch wire is inserted into the connecting hole 10 and fixed by the clamping bolts 15 above the connecting hole 10, thus completing the connection between the main wire, the branch wire, and the conductive block 8.

[0023] Both sides of the upper and lower shells are fixed with horizontal plates 3. Each horizontal plate 3 has a threaded screw 4 threaded through its surface. An arc-shaped clamping piece 5 is rotatably connected to the opposite side of the screw 4, and a rubber pad is also glued to the opposite side of the clamping piece 5. After the cable is connected to the conductive block 8, a portion of the sealing piece 7 is peeled off according to the cable thickness. Then, the upper and lower shells are joined together and fixed with bolts on the fixing edge 2. At this time, the remaining sealing piece 7 will adhere to the outer wall of the cable, which can both clamp the cable and provide good waterproofing. Finally, the screw 4 is rotated, and the screw 4 will move along the threaded hole of the horizontal plate 3, driving the clamping piece 5 to move closer to the cable. The clamping piece 5 clamps and fixes the cable. The rubber pad can prevent the clamping piece 5 from directly contacting the cable and causing wear, while increasing friction to improve the clamping effect and prevent the cable from being pulled away by external forces and separating from the conductive block 8, further increasing the stability of the cable connection.

[0024] The accompanying drawings in this application are for illustrative purposes only.
