Abstract
Description
Technical Field
[0001] This utility model relates to the field of detonator blasting technology, and more specifically, to a manual wire pressing tool. Background Technology
[0002] Waterproof wire clips are commonly used in detonator blasting. A typical waterproof wire clip consists of an upper and lower housing, hinged at one end and snapped together at the other. The lower housing contains two spaced-apart mounting bases, each with a conductive wire clip for connecting the detonating mainline and lead wires. The upper housing has two crimping bases corresponding to the two conductive wire clips. Each conductive wire clip has an upward-facing mainline slot and lead wire slot at its top. Therefore, before using the waterproof wire clip, the mainline and lead wire slots of the conductive wire clip must first be embedded with wire.
[0003] However, in the field of detonator blasting, the wire crimping is currently done manually, as there are no usable tools available on the market, and it is generally done manually. Without the assistance of professional tools, the entire process of crimping wires is extremely complicated. This not only leads to inconsistent crimping quality but also greatly reduces work efficiency and causes many inconveniences for related operations. Utility Model Content
[0004] The technical problem this invention aims to solve is the significant market gap in the field of manual wire crimping tools for detonators, which leads to inconsistent crimping quality and low work efficiency. To overcome these shortcomings of existing technologies, this invention provides a manual wire crimping tool for waterproof wire clamp applications in the field of detonator blasting. It aims to fill the gap in the industry's wire crimping tool market, solve the complexity of operation without tools, standardize the wire crimping process, and thus reduce the user's operational burden.
[0005] A manual crimping tool includes a handle and a crimping rod fixed to the handle. The crimping rod has a groove at its free end along the axial direction. The groove has a first groove wall and a second groove wall. The ends of the first groove wall and the second groove wall away from the free end are connected to form a U-shaped structure. The free ends of the first groove wall and the second groove wall are both provided with trapezoidal opening slots, and the wide opening of the trapezoidal opening slots faces the free end.
[0006] Compared with existing technologies, this invention has the following advantages: This application is the first to invent a manual wire crimping tool. The trapezoidal opening of the tool is used to fix the busbar or lead wire. The wide opening of the trapezoidal slot faces upwards to ensure that the tool can easily release the wire after it is properly secured in the wire clip. The U-shaped groove is used when the tool clamps the wire and then rests across the side wall of the conductive wire clip. The depth of the U-shaped groove is preferably greater than the depth of the busbar and lead wire clips of the conductive wire clip, ensuring that the busbar or lead wire is fully engaged in the bottom of the busbar and lead wire clips. Due to the tool's consistency, the wire clip crimping quality is uniform. The tool replaces manual wire crimping, is convenient to operate, and has a standardized process, resulting in high work efficiency. The tool's components have a simple structure and are easy to operate.
[0007] In one possible implementation, the two trapezoidal opening slots are arranged symmetrically.
[0008] In the above scheme, the symmetrical arrangement takes into account that the same busbar or lead wire is usually crimped in one operation. The symmetrical trapezoidal opening slots can ensure the consistency and coordination of the crimping, resulting in high crimping quality.
[0009] In one possible implementation, the bottom angles of the two trapezoidal opening slots are set with an arc transition.
[0010] In the above scheme, the arc transition design at the bottom corner of the slot facilitates the insertion of the busbar or lead wire.
[0011] In one possible implementation, anti-slip textures are provided on the inner wall surfaces of the two trapezoidal opening slots.
[0012] In the above solution, the anti-slip texture prevents the clamped busbar or lead wire from falling out again. A better design would be to make the anti-slip texture a barbed structure, which would provide greater resistance and make it easier for the clamped wire to fall into the busbar and lead wire slots.
[0013] In one possible implementation, the ends of the first and second trench walls furthest from the free end are connected by an arc-shaped transition connection.
[0014] In the above scheme, the arc transition between the two groove walls of the U-shaped structure can reduce the collision and damage to the side wall of the wire clip during the tool operation.
[0015] In one possible implementation, thinning planes are provided on the opposite surfaces of the first and second tank walls, and the thinning planes extend to below the bottom of the U-shaped tank.
[0016] In the above scheme, the thinning plane setting prevents the first and second groove walls from becoming too thick, thus allowing the first and second groove walls to have a certain degree of toughness, which can better engage the wire clamp side wall when clamping the wire.
[0017] In one possible implementation, smooth end faces are provided on the parallel end faces of the first and second groove walls, and the smooth end faces extend to below the bottom of the U-shaped groove.
[0018] In the above solution, the smooth end face design prevents the crimping tool from cutting the side wall of the conductive wire clip due to unevenness when crimping the busbar or lead wire. In addition, the smooth end face design corresponds to the thinning plane, ensuring both toughness and aesthetics.
[0019] In one possible implementation, the depth of the U-shaped structure formed by the first and second groove walls is greater than the depth of the busbar slot and lead wire slot of the conductive wire clamp.
[0020] In the above scheme, the depth of the U-shaped structure is large enough to ensure that the cable can go all the way into the bottom of the busbar slot and the lead wire slot, resulting in better cable burial consistency.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. The manual crimping tool of this utility model mainly consists of two parts: a handle and a crimping rod. At the free end of the crimping rod, a long U-shaped groove is carefully designed on the front, while a trapezoidal opening groove is designed on the side. This unique structural design lays the foundation for achieving efficient crimping operations.
[0023] 2. During use, first use the trapezoidal slot on the side to firmly press the wire in place, and then accurately press the wire into the corresponding slot of the wire clip to complete the crimping operation. The whole process is simple, quick and easy to master.
[0024] 3. The structure of this utility model is simple and clear, the manufacturing process is simple, the production cost is low, and it is extremely convenient and easy to operate.
[0025] 4. This tool is lightweight, easy to carry and use, and has wide applicability, meeting the wiring crimping needs of various wire diameters and materials, and has extremely high practical value. Attached Figure Description

[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0040] See Figures 1-5 As shown in the illustration, this application discloses a manual crimping tool, aiming to fill the gap in the industry for crimping tools, solve the complexity problem of operation without tools, standardize the crimping operation process, and thus reduce the user's operational burden. The manual crimping tool of this invention mainly consists of a handle 10 and a crimping rod 20 fixed to the handle. At the free end of the crimping rod 20, a long U-shaped groove is carefully designed on the front, while a trapezoidal opening slot 22 is designed on the side. This unique structural design lays the foundation for achieving efficient crimping operations.
[0041] See Figures 1 to 4 As shown, the manual crimping tool of this embodiment includes a handle 10 and a crimping rod 20 fixed to the handle. There are no particular restrictions on the method or angle of fixing the crimping rod 20 to the handle 10. Preferably, the crimping rod 20 is fixed to the axis of the handle 10, thus forming a structure similar to a screwdriver, which facilitates manufacturing. A U-shaped groove is provided at the free end of the crimping rod 20, having a first groove wall 21 and a second groove wall 23. The ends of the first groove wall 21 and the second groove wall 23 away from the free end are connected to form a U-shaped structure. Trapezoidal openings 22 are provided at the free ends of both the first groove wall 21 and the second groove wall 23, with the wide opening of the trapezoidal opening 22 facing the free end.
[0042] During use, the wire 30 is first firmly pressed down using the trapezoidal slot 22 on the side. Then, the wire 30 is precisely pressed into the corresponding slot of the conductive wire clip 40 to complete the crimping operation. The whole process is simple, quick and easy to master.
[0043] See Figure 2 In some embodiments, to facilitate the insertion and removal of the wire 30, the bottom corners of the two trapezoidal opening slots 22 are set with an arc transition.
[0044] Preferably, the inner wall surface of the two trapezoidal opening slots 22 is provided with anti-slip textures 221. A more preferred design is to design the anti-slip textures 221 as barbed structures, which provides greater resistance and facilitates the wires 30 falling into the busbar slots and lead wire slots.
[0045] In other embodiments, the ends of the first groove wall 21 and the second groove wall 23 away from the free end are connected by an arc-shaped transition connection.
[0046] Please continue reading Figure 3 The dimensions of the pressure bar 20 and the shape of the top trapezoidal opening groove 22 can be appropriately modified within a certain range, which can also achieve a good pressure effect and realize the intended purpose of the present invention.
[0047] See Figure 3 and Figure 4 In some embodiments, the pressing rod 20 of the manual wire pressing tool provided in this application has thinning planes on the opposing surfaces of the first groove wall 21 and the second groove wall 23, extending below the bottom of the U-shaped groove. The parallel end faces of the first and second groove walls each have smooth end faces extending below the bottom of the U-shaped groove. The thinning planes allow the first and second groove walls to have a certain degree of flexibility, enabling better insertion into the side wall of the wire clamp when pressing the wire. The smooth end faces prevent the wire pressing tool from cutting the side wall of the conductive wire clamp due to unevenness when pressing the busbar or lead wire. Furthermore, the smooth end faces correspond to the thinning planes, ensuring both flexibility and aesthetics.
[0048] In summary, the core technical innovation of this invention, as presented in the above embodiments, lies in the structural design of the pressure bar 20. Its unique combination of a long U-shaped groove and a trapezoidal opening slot 22 provides crucial support for achieving efficient and standardized pressure bar operations. This is also the key technical element for which this invention seeks patent protection. (From a view of actual use...) Figure 4 and Figure 5 As can be seen, the wire pressing tool of the present invention can easily press the busbar or lead wire into the conductive wire clip.
