Description

Technical Field

[0001] This utility model relates to the field of electronic detonator line card technology, specifically to an electronic detonator line card. Background Technology

[0002] Electronic detonators are detonators that use an electronic control module to control the ignition timing and ignition energy. During use, wire clamps are needed to connect the lead wires of the electronic detonator to the busbar to ensure the smooth progress of blasting operations. They are safe and reliable and can effectively prevent detonator misoperation and accidental disassembly.

[0003] When the leads of an electronic detonator are inserted into the clamp, they need to be split before being connected. Therefore, existing electronic detonator clamps usually have a threading groove to limit the lead wires after splitting. However, the threading groove is small, and the outer sheath is easily damaged after the lead wire is inserted. In addition, usually only a single pressure block is used to press and fix the lead wire and the main wire. Since the lead wire and the main wire are at different heights, the fixing effect is poor. Utility Model Content

[0004] The purpose of this invention is to provide an electronic detonator line card to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic detonator wire clamp, comprising a lower cover, an upper cover hinged to one end of the lower cover, a base disposed inside the lower cover, and a wire clamping terminal mounted on the base. The inner wall of the lower cover is provided with a partition, and a wire-passing groove is formed between the partition and the lower cover. A foot wire groove is provided at the end of the lower cover away from the upper cover, and the foot wire groove communicates with the wire-passing groove. A limiting frame is provided inside the upper cover. Busbar pressing parts are provided on the left and right sides of the limiting frame. First foot wire pressing blocks are provided on the front and rear sides of the limiting frame. Second foot wire pressing blocks are symmetrically provided on the inner sidewall of the limiting frame. A busbar pressing block is provided between the two second foot wire pressing blocks.

[0006] As a preferred embodiment of this utility model, the left and right sides of the wire clamping terminal are provided with busbar slots, the front and rear sides of the wire clamping terminal are provided with lead wire slots, and the bottom of the wire clamping terminal is provided with multiple pins.

[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] Please see Figures 1 to 5This utility model provides a technical solution: an electronic detonator wire clamp, including a lower cover 1, an upper cover 2 hinged to one end of the lower cover 1, a base 16 disposed inside the lower cover 1, and a wire clamping terminal 8 mounted on the base 16. The inner wall of the lower cover 1 is provided with a partition 7, which is used to separate the lead wires after splitting. A wire-passing groove 6 is formed between the partition 7 and the lower cover 1. The wire-passing groove 6 has a large space, preventing damage to the lead wire's outer sheath. A lead wire groove 4 is opened at the end of the lower cover 1 away from the upper cover 2. The lead wire enters the lower cover 1 through the lead wire groove 4, and the lower cover 1 and the upper cover 2 cooperate to clamp and fix the lead wire in the lead wire groove 4. The lead wire groove 4 communicates with the wire-passing groove 6. A limiting frame 10 is provided inside the upper cover 2, which can restrain the wire clamping terminal 8. The limiting function reduces the deformation of the clamping terminal 8 when the lead wire or busbar is pulled. The left and right sides of the limiting frame 10 are provided with busbar pressing parts 11, and the front and rear sides of the limiting frame 10 are provided with first lead wire pressing blocks 9. The inner sidewall of the limiting frame 10 is symmetrically provided with second lead wire pressing blocks 13. The second lead wire pressing blocks 13 and the first lead wire pressing blocks 9 are at the same horizontal height. Both the first lead wire pressing blocks 9 and the second lead wire pressing blocks 13 are used to press the lead wire. A busbar pressing block 14 is provided between the two second lead wire pressing blocks 13. The busbar pressing block 14 and the busbar pressing parts 11 are at the same horizontal height and lower than the second lead wire pressing blocks 13, so as to press the busbar. Thus, the busbar and lead wire can be pressed separately when they are at different heights, so as to achieve a better fixing effect.

[0019] The cable clamping terminal 8 has busbar clamping slots 81 on both the left and right sides. When the busbar is clamped into the busbar clamping slot 81, the busbar clamping slot 81 will pierce the outer sheath of the busbar. The cable clamping terminal 8 has lead wire clamping slots 82 on both the front and rear sides. When the lead wire is clamped into the lead wire clamping slot 82, the cable clamping terminal 8 will pierce the outer sheath of the lead wire clamping slot 82. The bottom of the cable clamping terminal 8 has multiple pins 83.

[0020] Both sides of the lower cover 1 and the upper cover 2 are provided with busbar grooves 15, which are used for the busbar to pass through.

[0021] One end of the upper cover 2 is provided with a curved part 12, which can deform. When the curved part 12 deforms, it will drive the locking block 3 to move, so as to facilitate the separation of the locking block 3 from the slot 5. The side of the curved part 12 is provided with a locking block 3, and the lower cover 1 is provided with a slot 5 that cooperates with the locking block 3. The locking block 3 and the slot 5 cooperate to fix the lower cover 1 and the upper cover 2.

[0022] The base 16 is provided with a fixing groove 17 that mates with the pin 83. The fixing groove 17 and the pin 83 are used to fix the wire clamp terminal 8. The pin 83 and the fixing groove 17 are interference fit. When the interference fit is made, the pin 83 can be more firmly inserted into the fixing groove 17.

[0023] Specifically, during wiring, the lead wires are placed on the lead wire slot 82 and the busbar is placed on the busbar slot 81. Then, the lower cover 1 and the upper cover 2 are fastened together. The first lead wire clamping block 9 and the second lead wire clamping block 13 cooperate to press the lead wire into the lead wire slot 82, and the busbar clamping part 11 and the busbar clamping block 14 cooperate to press the busbar into the busbar slot 81. During this process, the wire clamping terminal 8 will pierce the outer sheath of the lead wire and the busbar to ensure electrical connection between the lead wire and the busbar. After the lower cover 1 and the upper cover 2 are fastened together, the clamping block 3 will be inserted into the empty slot 5 to fix the lower cover 1 and the upper cover 2.
