Abstract
Description
Technical Field
[0001] This utility model relates to the field of detonator lead wire technology, specifically to a lead wire with good waterproof effect. Background Technology
[0002] The detonator lead wire is an important component of an electric detonator, used to introduce the initiation current into the detonator, thereby detonating the explosive inside. Detonator lead wires are usually made of copper or iron core wires, wrapped with insulating plastic. The wire body is generally waterproof. However, at the connection clamp at one end of the lead wire, the insulating plastic often needs to be peeled off and clamped in a wire clamp to facilitate the connection to the busbar. After being connected to the busbar, the waterproof effect is poor, which affects the normal initiation. Utility Model Content
[0003] The technical problem this invention aims to solve is that existing lead wire connectors require the removal of insulating plastic at the connection point to facilitate busbar connection, but this area is prone to moisture and has poor waterproofing after connection to the busbar, affecting normal detonation.
[0004] To solve the above problems, the technical solution adopted by this utility model is a waterproof lead wire, including a lead wire body, a connecting clip structure at one end of the lead wire body, the connecting clip structure including a base frame, a pair of wire clamps fixed inside the base frame, a pair of openings on one side of the base frame, one end of the lead wire body passing through the openings and being clamped in the wire clamps, an internal threaded cylinder fixed in the middle of the base frame, a sealing cap on the top of the base frame, a tightening bolt rotatably connected to the internal threaded cylinder in the middle of the sealing cap, a sealing groove on the upper edge of the base frame, a sealing deep groove on the upper side of the internal threaded cylinder, and a sealing frame and a sealing cylinder fixed on the lower side of the sealing cap at the sealing groove and the sealing deep groove, respectively.
[0005] As a further embodiment of this utility model: a pair of slots are provided on the sides of the base frame and the sealing frame, and a busbar is threaded through the slot. The busbar is snapped into the wire clamp, and the busbar and the lead wire body are at a 90-degree angle, which facilitates observation of the connection between the busbar and the lead wire body.
[0006] As a further embodiment of this utility model: the wire clamp is made of metal, and the side of the wire clamp has two pairs of slot structures with blade-like edges to facilitate cutting the insulating plastic on the outside of the busbar and lead wire body.
[0007] As a further embodiment of this utility model: a pressure block is fixed on the lower side of the sealing cover above the wire clamp, which facilitates pressing the busbar and allows the slot on the side of the wire clamp to cut the insulating plastic of the busbar, so that the wire clamp can be connected to the inside of the busbar.
[0008] As a further embodiment of this utility model, a knob is fixed at the top of the tightening bolt for easy manual rotation.
[0009] Compared with the prior art, the advantages of this utility model are as follows: This application adds a base frame and a sealing cover structure, and sets a mutually cooperating sealing groove, sealing deep groove and sealing frame and sealing cylinder between the base frame and the sealing frame, which can effectively prevent the problem of moisture from occurring after the busbar and the lead wire body are connected.

[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. 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.
[0018] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0019] Combined with appendix Figure 1-4It can be seen that the device includes a lead wire body 1, one end of which is equipped with a connecting clip structure for connecting the busbar 9 and the lead wire body 1. The connecting clip structure includes a base frame 2, and a pair of wire clamps 3 are fixed inside the base frame 2. The wire clamps 3 are made of metal to facilitate power transmission. The wire clamps 3 have two pairs of slot structures on their sides, and the edges of the slots are blade structures to facilitate cutting the insulating plastic on the outside of the busbar 9 and the lead wire body 1. A pair of openings 2.2 are opened on one side of the base frame 2, and one end of the lead wire body 1 passes through the openings 2.2 and is clamped into the wire clamps 3. An internally threaded cylinder 4 is fixed in the middle of the base frame 2. A sealing cover 5 is provided on the top of the base frame 2. A tightening bolt 6 is rotatably connected to the internally threaded cylinder 4 in the middle of the sealing cover 5, so as to make the sealing cover 5 and the base frame 2 tightly connected. A knob 11 is fixed on the top of the tightening bolt 6, so as to make manual rotation easy. A pressure block 10 is fixed on the lower side of the sealing cover 5 above the clamp 3, so as to press the busbar 9, so that the slot on the side of the clamp 3 can cut the insulating plastic of the busbar 9, so that the clamp 3 can be connected to the inside of the busbar 9.
[0020] Combined with appendix Figure 1 , 2 It can be seen that a sealing groove 2.1 is provided on the upper edge of the base frame 2, a sealing deep groove 4.1 is provided on the upper side of the internal threaded cylinder 4, and a sealing frame 7 and a sealing cylinder 8 are fixed on the lower side of the sealing cover 5 at the sealing groove 2.1 and the sealing deep groove 4.1 respectively. A pair of slots are provided on the sides of the base frame 2 and the sealing frame 7, and a busbar 9 is passed through the slot. The busbar 9 is clamped in the wire clamp 3. The busbar 9 and the lead wire body 1 are at a 90-degree angle, which makes it easy to observe the connection between the busbar 9 and the lead wire body 1.
[0021] The working principle of this application is as follows: During production, the connecting clamp structure and the lead wire body 1 are in a connected state. The lead wire body 1 passes through the opening 2.2 and connects with the clamp 3. When it is necessary to connect with the busbar 9, the bolt 6 is rotated and tightened so that there is enough space between the sealing cover 5 and the base frame 2 for the busbar 9 to be placed. The busbar 9 is placed in the slot, and then the bolt 6 is rotated and tightened so that the pressure block 10 can squeeze the busbar 9 into the clamp 3. At the same time, the sealing frame 7 and the sealing cylinder 8 are engaged in the sealing groove 2.1 and the sealing deep groove 4.1. At this time, the connecting clamp structure is in a sealed state, ensuring that the connection between the busbar 9 and the lead wire body 1 will not be affected by moisture, thus having a waterproof function.
[0022] 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. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
