Abstract
Description
Technical Field
[0001] This utility model relates to the field of detonator busbar connection technology, specifically to a quick-connect connector for blasting lines. Background Technology
[0002] The detonator busbar connection joint enables a quick and reliable connection between the detonator lead wire and the busbar;
[0003] Busbar connection clamps are mostly clamp-type structures, including a pair of hinged clamp frames. Each clamp frame contains a wire clamp, and the wire clamp has four locking interfaces on its sides. These interfaces have blades to easily cut through the insulating plastic. The lead wires are pre-connected to the wire clamps. When connecting the busbar, the busbar needs to be placed on top of the wire clamp, and the other clamp frame presses the busbar into the clamp to facilitate electrical connection between the wire clamp and the lead wires, thus aiding in detonation. However, existing connection clamps generally use a clamp frame structure that, when closed, uses clips and protrusions for engagement. Connecting the busbar requires manually prying open the pair of clamp frames, connecting the busbar, and then fastening the clamp frames back together. In detonation operations, several lead wires need to be connected to the busbar, making the operation cumbersome. Furthermore, the clamp frames are typically made of plastic, which can easily damage the clips when prying them open, affecting usability. Utility Model Content
[0004] The technical problem this utility model aims to solve is that the existing connecting clamp frame structure relies on the snap-fit protrusion for closure, requiring the connecting busbar to be manually pried open and then snapped back on, which is cumbersome and the plastic clamp frame is easily damaged.
[0005] To solve the above problems, the technical solution adopted by this utility model is a quick-connect connector for blasting lines, including a clamp body 1 and a clamp body 2 that are hinged to each other. Two pairs of limiting blocks are fixed on the lower side of the clamp body 1, and a pair of limiting plates are fixed on the upper side of the clamp body 2. A wire clamping structure is provided between the limiting plates and the limiting blocks. A threaded hole is opened at one end of the lower side of the clamp body 1, and a fastening screw is rotatably provided in the threaded hole. A clamping plate is provided outside the fastening screw. A lead wire is clamped between the clamping plate and the clamp body 1. A locking plate is fixed on both sides of the clamp body 1 and the clamp body 2.
[0006] As a further embodiment of this utility model: a hinge shaft is provided at the hinge joint between clamp body one and clamp body two, and a non-metallic elastic sheet is sleeved on the outside of the hinge shaft, which has a certain elasticity to facilitate the rebound between clamp body one and clamp body two. An opening is provided on the side of the non-metallic elastic sheet at the foot line to facilitate the foot line to pass through.
[0007] As a further embodiment of this utility model: the wire clamp structure includes a base plate, and an open clamp body is fixed on both the upper and lower sides of the base plate. A blade structure is provided on the side of the clamp body. The wire clamp structure is made of metal, which facilitates the connection between the busbar and the lead wire.
[0008] As a further embodiment of this utility model: a busbar is clamped in the bayonet plate, and both the busbar and the lead wire are clamped in the clamping structure, which makes it easy for the clamping structure to cut the outer enameled wire of the busbar, thereby making contact between the inside of the busbar and the clamping structure. The limiting plate is pressed on the upper side of the busbar, which facilitates better cutting of the busbar.
[0009] As a further embodiment of this utility model: both the fastening screw and the clamp are made of non-metallic materials, and an opening is provided on the upper side of the clamp body at the fastening screw, so as to facilitate the adjustment of the tightness of the fastening screw with a screwdriver.
[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adopts a clamping structure, which can open the clamping body one and clamping body two by the index finger and thumb to facilitate clamping the busbar. Then, by pressing, it is easy to quickly connect the lead wire and the busbar. The structure is simple and the operation is convenient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0020] Combined with appendix Figure 1 , 3 4. It can be seen that the clamp body 1 and clamp body 2 are hinged to each other. A hinge shaft 10 is provided at the hinge point between the clamp body 1 and clamp body 2. A non-metallic elastic sheet 11 is sleeved on the outside of the hinge shaft 10. It has a certain elasticity and makes it easy for the clamp body 1 and clamp body 2 to rebound. An opening is provided on the side of the non-metallic elastic sheet 11 at the lead wire 8 so that the lead wire 8 can pass through. Two pairs of limiting blocks 3 are fixed on the lower side of the clamp body 1 and a pair of limiting plates 4 are fixed on the upper side of the clamp body 2. A wire clamping structure 5 is provided between the limiting plate 4 and the limiting block 3, which can limit the position of the wire clamping structure 5. The wire clamping structure 5 includes a base plate. Open clamp bodies are fixed on the upper and lower sides of the base plate. A blade structure is provided on the side of the clamp body. The wire clamping structure 5 is made of metal so that the busbar 12 and the lead wire 8 can be energized.
[0021] Combined with appendix Figure 1-3 It can be seen that a threaded hole is opened at one end of the lower side of clamp body 1, and a fastening screw 6 is installed in the threaded hole. Both the fastening screw 6 and the clamping plate 7 are made of non-metallic materials. An opening is opened on the upper side of clamp body 2 at the location of the fastening screw 6, which facilitates the adjustment of the tightness of the fastening screw 6 with a screwdriver. A clamping plate 7 is provided on the outside of the fastening screw 6. A lead wire 8 is clamped between the clamping plate 7 and clamp body 1. Both sides of clamp body 1 and clamp body 2 are fixed with a bayonet plate 9. A busbar 12 is clamped in the bayonet plate 9, and both the busbar 12 and the lead wire 8 are clamped in the wire clamping structure 5, which facilitates the wire clamping structure 5 to cut the outer enameled wire of the busbar 12, thereby making contact between the inside of the busbar 12 and the wire clamping structure 5. The limiting plate 4 is pressed on the upper side of the busbar 12 to facilitate better cutting of the busbar 12.
[0022] The working principle of this application is as follows: During production, the connecting clamp structure and the lead wire 8 are in a connected state and are fixed to the clamp body 1 by the clamp plate 7. One end of the lead wire 8 is clamped to the lower side of the clamp structure 5. The blade of the clamp structure 5 cuts the enameled wire on the outside of the lead wire 8, thereby achieving contact between the clamp structure 5 and the inside of the lead wire 8. When connecting the busbar 12, use the index finger and thumb to press one end of the clamp body 1 and the clamp body 2, so that the end with the jaw plate 9 opens. The busbar 12 can then be placed at the jaw of the jaw plate 9. At the same time, use the thumb and index finger to press the clamped end of the busbar 12 so that the busbar 12 can be pressed down by the limiting plate 4, so that the clamp structure 5 can cut the busbar 12, thereby achieving electrical connection between the busbar 12 and the lead wire 8. The operation is simple and convenient.
[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
