Description

Technical Field

[0001] This utility model relates to the field of detonator busbar connection technology, specifically to a busbar connector that is easy to install and has high reliability. Background Technology

[0002] Detonator bus connectors enable quick and reliable connection between detonator leads and the busbar;

[0003] Busbar connection clamps are mostly clamp-type structures, including a pair of 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 above the wire clamp, and the other clamp frame presses the busbar into the wire clamp to facilitate electrical connection between the wire clamp and the lead wires, thus aiding in detonation. However, in existing connection clamp structures, if the blades at the locking interfaces are not sharp enough, they may not be able to cut through the external insulating plastic of the busbar, leading to connection failure and affecting normal detonation. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing connector clamp structures, if the blade at the clamp interface is not sharp enough, it may fail to cut through the external insulating plastic of the busbar, leading to connection failure and affecting normal detonation.

[0005] To solve the above problems, the technical solution adopted by this utility model is a busbar connector that is easy to install and has high reliability. The connector includes a connecting clip structure, which includes a base frame and a pressure frame. The inner side of the base frame is divided into four areas by a cross partition. A metal wire clamp is provided between two diagonally opposite areas. The metal wire clamp structure is horizontally Ω-shaped and a piercing needle is fixed on the upper side. A pair of limiting plates are fixed above the metal wire clamp between the cross partition and the inner side of the mechanism. A fine wire hole is opened on one side of the base frame. A slot is opened between the base frame and the pressure frame. A lead wire is passed through the fine wire hole. The busbar body is clamped in the slot.

[0006] As a further embodiment of this utility model: the pressure frame and the base frame are hinged to each other at one end, the base frame is fixed with a boss at the other end, and the pressure frame is fixed with a snap-fit ​​plate fastened to the outside of the boss at the other end, so as to facilitate a tight connection between the base frame and the pressure frame.

[0007] As a further embodiment of this utility model: one end of the lead wire is stripped of its outer insulation sheath and inserted into a metal wire clip for easy and stable connection.

[0008] As a further embodiment of this utility model: the busbar body is limited between a pair of limiting plates and inserted on the outside of the puncture needle, so that the metal clamp is connected to the inside of the busbar body.

[0009] As a further embodiment of this utility model: a pressure block is fixed on the upper side of the pressure frame above the busbar body, which facilitates pressing the busbar body into the puncture needle.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds a new type of metal clip structure, which can remove the enameled wire at one end of the lead wire beforehand and connect it with the metal clip. Then, when installing the busbar, the wire can be directly inserted into the busbar through a piercing needle, which prevents the enameled wire from failing to pass through the busbar. This makes the reliability higher and the device simpler to use. 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 1-4It can be seen that the connection clamp structure includes a base frame 1 and a pressure frame 2. The inner side of the base frame 1 is divided into four areas by a cross partition 3. A metal wire clamp 4 is provided between two diagonally opposite areas to facilitate the connection of the lead wire 8 and the busbar body 9. The metal wire clamp 4 has a horizontal Ω-shaped structure to facilitate clamping the lead wire 8, and a piercing needle 4.1 is fixed on the upper side to facilitate the connection of the busbar body 9. A pair of limiting plates 5 are fixed above the metal wire clamp 4 between the cross partition 3 and the inner side of the mechanism to limit the position of the busbar body 9.

[0021] Combined with appendix Figure 3 It can be seen that a fine wire hole 6 is opened on one side of the base frame 1, and a slot 7 is opened between the base frame 1 and the pressure frame 2. A lead wire 8 is passed through the fine wire hole 6. One end of the lead wire 8 is stripped of the outer insulation sheath and inserted into the metal wire clamp 4 for easy connection and stability. The busbar body 9 is clamped in the slot 7. The busbar body 9 is limited between a pair of limiting plates 5 and inserted on the outside of the puncture needle 4.1, so that the metal wire clamp 4 is connected to the inside of the busbar body 9. The pressure frame 2 and one end of the base frame 1 are hinged to each other. A boss is fixed on the other end of the base frame 1. A snap-fit ​​plate is fixed on the outside of the boss on the other end of the pressure frame 2 to facilitate a tight connection between the base frame 1 and the pressure frame 2. A pressure block 10 is fixed on the upper side of the pressure frame 2 above the busbar body 9 to facilitate pressing the busbar body 9 into the puncture needle 4.1.

[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. One end of the lead wire 8 will be stripped of its enameled wire, pass through the fine wire hole 6, and be snapped into the metal wire clamp 4. Then, when connecting the busbar body 9, the base frame 1 and the pressure frame 2 are opened, and the busbar body 9 is placed in the slot 7, above the piercing needle 4.1, and between a pair of limiting plates 5. Then the base frame 1 and the pressure frame 2 are closed, so that the pressure block 10 can press the piercing needle 4.1 into the busbar body 9. At the same time, the lead wire 8 can be further clamped, thereby realizing the connection between the lead wire 8 and the busbar body 9. It is safe and reliable. At the same time, the base frame 1 and the pressure frame 2 are fixed by the snap-fit ​​plate and the boss.
