A combination wire connector

Abstract

This utility model discloses a combined wire connector, relating to the technical field of wire connectors. The utility model includes a connector box with two pressing blocks slidingly fitted to its inner wall. Two movable openings are formed on both sides of the inner wall of the connector box, and trigger rods are rotatably fitted to the inner walls of each movable opening. Springs are installed between the trigger rods and the movable openings. Drive blocks that contact the trigger rods are fixedly connected to both sides of the two pressing blocks. By setting the trigger rods, this utility model allows the driving blocks to push the corresponding springs when the pressing blocks move, and then pushes the clamping blocks through the other end of the trigger rods, causing the clamping blocks to clamp the wire in the hollow tube. This ensures that even if the wire is torn during use, the clamping blocks hold the wire, reducing the possibility of loosening or separation from the conductive parts of the connector box, which could lead to poor conductivity and thus improving stability during use.

Description

Technical Field

[0001] This utility model belongs to the technical field of wire connectors, specifically, it relates to a combined wire connector. Background Technology

[0002] Existing connectors are pluggable connectors, typically used in industrial applications, where most plugs are modular for easy everyday use.

[0003] Chinese patent CN215816542U discloses a combined wire connector. The connector has a plug-in structure slidably connected to the upper and lower ends of the inner side of the housing. A pushing structure is located at the center of the upper end of the housing, and a pressing structure is located on the inner side of the housing. The plug-in structure includes a hollow tube, with an arc-shaped component fixedly connected to one end of the hollow tube facing the housing, and a conductive sheet fixedly connected to the other end of the arc-shaped component. This technical solution involves wires passing through the hollow tube and connecting to the conductive sheets, then inserting them into the housing, and finally securing them with the pressing structure. However, in actual use, when subjected to external pulling, the wires slide within the hollow tube, pulling on the two conductive sheets. This can cause the contact points between the wires and the conductive sheets to loosen or even detach, resulting in wire breakage and reduced stability during use.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a combined wire connector.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A combined wire connector includes a connector box. The inner wall of the connector box has two pressing blocks that slide together. Two movable openings are opened on both sides of the inner wall of the connector box. The inner wall of each movable opening is rotatably fitted with a trigger rod. A spring is installed between the trigger rod and the movable opening. A drive block that contacts the trigger rod is fixedly connected to both sides of the two pressing blocks.

[0008] Two plug-in boxes are installed on the upper and lower sides of the connector box. Two movable slots are opened on one side of the inner wall of each plug-in box. The inner wall of each movable slot is slidably and elastically fitted with a locking block that contacts the trigger rod. A hollow tube is installed on one side of each plug-in box.

[0009] The inner wall of the connecting box is equipped with a drive mechanism that cooperates with the two extrusion blocks.

[0010] Optionally, the drive mechanism includes a fixed block fixedly connected to the inner wall of the connector box, a double-acting lead screw rotatably engaged with one side of the fixed block and threadedly meshing with the two pressing blocks, a worm gear fixedly connected to the double-acting lead screw, and a worm gear rotatably engaged with one side of the inner wall of the connector box and meshing with the worm gear. Rotating the worm gear drives the worm gear and the double-acting lead screw to rotate. The rotation of the double-acting lead screw within the two pressing blocks pushes the two pressing blocks to move in opposite directions, thus clamping and fixing the connector box.

[0011] Optionally, elastic pads are fixedly connected to one side of each of the multiple clamping blocks. When the clamping blocks clamp the wire, the elastic pads act as an intermediate medium, reducing the possibility of damage to the wire insulation during clamping.

[0012] Optionally, a knob located on one side of the connector box is fixedly connected to one end of the worm gear, and an anti-slip pad is fixedly connected to the knob. The knob facilitates operation of the worm gear, and the anti-slip pad increases the friction for knob operation, improving ease of operation.

[0013] Optionally, two hand grips are fixedly connected to opposite sides of the two connector boxes, and each hand grip has an anti-slip groove on one side. The hand grips facilitate easy handling of the connector boxes, and the anti-slip grooves increase the grip's anti-slip properties.

[0014] Optionally, sealing gaskets are installed on adjacent sides of the two connector boxes. When the connector boxes are connected to the connection box, the connection position can be sealed by squeezing the sealing gaskets, reducing internal moisture and improving the sealing performance of the connector.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] By setting a trigger rod, when the squeezing block moves, the corresponding spring is pushed by the drive block, and then the other end of the trigger rod pushes the clamping block, so that the clamping block clamps the wire in the hollow tube. This means that if the wire is torn during use, the two clamping blocks will hold the wire under force, reducing the possibility of loosening or separation from the conductive part of the connector box, which would lead to poor conductivity, and thus improving the stability during use.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a combined wire connector, including a connector box 1. The inner wall of the connector box 1 has two pressing blocks 2 that slide together. Two movable openings 3 are opened on both sides of the inner wall of the connector box 1. The inner wall of each movable opening 3 is rotatably fitted with a trigger rod 4. A spring 5 is installed between the trigger rod 4 and the movable opening 3. A drive block 6 that contacts the trigger rod 4 is fixedly connected to both sides of the two pressing blocks 2.

[0028] Two plug-in boxes 7 are installed on the upper and lower sides of the connecting box 1. Two movable grooves 8 are opened on one side of the inner wall of the two plug-in boxes 7. The inner wall of the two movable grooves 8 is slidably and elastically fitted with a clamping block 9 that contacts the trigger rod 4. A hollow tube 10 is installed on one side of the two plug-in boxes 7.

[0029] Both the plug-in box 7 and the extrusion block 2 are provided with conductive plates for conducting electricity. This is existing technology and not an innovative part, so it will not be described in detail.

[0030] The inner wall of the connecting box 1 is equipped with a drive mechanism 11 that cooperates with the two extrusion blocks 2.

[0031] One application of this embodiment is as follows: In use, the wire is first passed through the hollow tube 10 and fixed, and then inserted into the connector box 1 to fix the wire. The two pressing blocks 2 are moved in opposite directions by operating the drive mechanism 11 to clamp and fix the wire.

[0032] When the drive mechanism 11 is operated, the pressing block 2 moves, which in turn drives the drive block 6 to move. The movement of the drive block 6 causes the corresponding trigger rod 4 to rotate. The trigger rod 4 pushes one side of the clamping block 9, so that the corresponding clamping block 9 firmly clamps the insulation layer of the wire in the hollow tube 10. When subjected to external force, the two clamping blocks 9 fix the wire, reducing the possibility of loosening at the connection between the wire and the junction box 7, reducing the possibility of power failure, and thus improving the stability during use.

[0033] By setting the trigger rod 4, when the squeezing block 2 moves, the driving block 6 pushes the corresponding spring 5 to move, and then the other end of the trigger rod 4 pushes the clamping block 9, so that the clamping block 9 clamps the wire in the hollow tube 10. This means that if the wire is torn during use, the two clamping blocks 9 will clamp the wire and reduce the possibility of the conductive part of the plug box 7 being loosened or separated due to force, resulting in poor conductivity, thereby improving the stability during use.

[0034] The driving mechanism 11 in this embodiment includes a fixed block 111 fixedly connected to the inner wall of the connecting box 1, a bidirectional lead screw 112 rotatably engaged with one side of the fixed block 111 and threadedly meshed with the two pressing blocks 2, a worm gear 113 fixedly connected to the bidirectional lead screw 112, and a worm 114 rotatably engaged with one side of the inner wall of the connecting box 1 and meshed with the worm gear 113. By rotating the worm 114, the worm gear 113 and the bidirectional lead screw 112 can be driven to rotate. By rotating the bidirectional lead screw 112 inside the two pressing blocks 2, the two pressing blocks 2 can be pushed to move in opposite directions to clamp and fix the plug-in box 7.

[0035] In this embodiment, an elastic pad 12 is fixedly connected to one side of each of the multiple clamping blocks 9. When the clamping block 9 clamps the wire, the elastic pad 12 serves as an intermediate medium to reduce the possibility of damage to the wire insulation layer during the clamping process.

[0036] In this embodiment, a knob 13 located on one side of the connecting box 1 is fixedly connected to one end of the worm gear 114. An anti-slip pad 14 is fixedly connected to the knob 13. The knob 13 facilitates the operation of the worm gear 114, and the anti-slip pad 14 increases the friction of the knob 13 during operation.

[0037] In this embodiment, two hand-held plates 15 are fixedly connected to opposite sides of the two plug boxes 7. Each hand-held plate 15 is provided with an anti-slip groove 16 on one side. The hand-held plates 15 facilitate the easy handling of the plug boxes 7, and the anti-slip groove 16 increases the anti-slip properties of the hand-held plates 15.

[0038] In this embodiment, sealing gaskets 17 are installed on the adjacent side of the two plug boxes 7. When the plug box 7 is connected to the connecting box 1, the connection position can be sealed by squeezing the sealing gasket 17, thereby reducing the possibility of internal moisture.

[0039] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
