[0030] To make the purpose, technical scheme and advantages of the present technical solution clearer and more explicit, the present technical solution will be further described in detail below in combination with specific embodiments. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present technical solution.

[0031] To solve the problem of water leakage at the position where the wiring clamp is penetrated by the main line 30 in the prior art, as shown in Figure 1 , the present embodiment proposes a wiring clamp for detonator ignition. The main purpose of the present wiring clamp is to solve the problem of difficulty in sealing the penetration position of the main line 30. The main body of the present wiring clamp includes a bottom shell 10 and an upper cover 20. In the present embodiment, the main line 30 is a wire material with a certain elasticity.

[0032] As shown in Figure 2 , the bottom shell 10 in the present embodiment includes a lower wiring structure 12 occupying the main area in the middle part, and a lower hinge structure 11 is arranged at the tail position of the lower wiring structure 12. In the present embodiment, the lower hinge structure 11 is a hinge column. The front end of the lower wiring structure 12 is a front structure plate 121, and the front part of the front structure plate forms a box structure 131. The box structure 131 is open upward, and in the present embodiment, the rear plate of the box structure 131 and the front part of the lower wiring structure 12 share the front structure plate 121.

[0033] The front plate of the box structure 131 is a buckle plate 133, and the connection between the buckle plate 133 and the bottom plate of the box structure 131 has a stepped structure 134. A main wire mounting table 135 extending vertically in the front-rear direction is arranged in the middle of the box structure 131, and the main wire mounting table 135 has a wire slot 1352 extending vertically, which extends through the front part of the box structure 131 to the inside of the lower wire structure 12, and the cross-sectional shape and size of the wire slot 1352 match the cross-sectional shape and size of the main wire 30. The main wire mounting table 135 has a sealing slot 1351 cut off in the width direction.

[0034] As shown in Figure 3 , two symmetrical hole structures are arranged on the buckle plate 133, which are holes matched with the buckle 27. The front wall of the box structure 131 has a protruding structure 1331 near the top corresponding to the wire slot 1352, and the enclosed angle of the front wall of the box structure 131 to the wire slot 1352 is not less than 225°.

[0035] As shown in Figure 4 , the main area of the upper cover 20 in this embodiment is the upper wire structure 22, and the tail of the upper wire structure 22 is the upper hinge structure 21. The upper hinge structure 21 in this embodiment is a round hole buckle matched with the lower hinge structure 11, and the two are matched to form a rotating connection. The front part of the upper wire structure 22 is a transition plate 23 formed by extending the bottom plate of the upper cover 20 forward, and the lower surface of the transition plate 23 is provided with a cross-shaped reinforcing rib 231. The front part of the reinforcing rib 231 is a curved connecting piece 24, and the longitudinal section of the curved connecting piece 24 is generally in the shape of a "U". The front part of the curved connecting piece 24 extends out a hand operation part 25. Two symmetrical buckles 27 are arranged on the front side of the curved connecting piece 24. At the same time, a front wire pressing plate 261 and a rear wire pressing plate 262 are arranged at the front and rear parts of the curved connecting piece 24, respectively, that is, at the positions corresponding to the transition plate 23 and the hand operation part 25.

[0036] The inside of the curved connecting piece 24 has a front-rear through interface slot 241 for avoiding the main wire mounting table 135, which extends upward from the lower middle part of the curved connecting piece 24. The inner side wall of the interface slot 241 is in close contact with the outer side wall of the main wire mounting table 135. The rear wall of the curved connecting piece 24 corresponding to the interface slot 241 protrudes in the direction of the slot of the interface slot 241 to form a matching plate 242; the main wire mounting table 135 has a sealing slot 1351 cut off in the width direction; when the bottom shell 10 and the upper cover 20 are buckled, the matching plate 242 is inserted into the sealing slot 1351, and the outer wall of the matching plate 242 and the inner wall of the sealing slot 1351 are in close contact.

[0037] In combination with Figures 1-4As shown, when the upper cover 20 is buckled on the bottom shell 10, the upper wiring structure 22 and the lower wiring structure 12 cooperate with each other to electrically connect the wires. In the present embodiment, the curved connecting piece 24 enters the inner cavity 132 of the box structure 131 and can be elastically deformed, and the buckle 27 at the front of the curved connecting piece 24 enters the hole structure on the buckle plate 133. This allows the upper cover 20 to be stably installed on the bottom shell 10. At this time, part of the outer wall of the curved connecting piece 24 tightly fits the inner wall of the box structure 131 and forms a certain seal. In addition, the inner side wall of the butt joint slot 241 tightly fits the outer side wall of the main wire mounting table 135 to form a seal. The rear wire pressing plate 262 presses the main wire 30 in the rear section of the wire slot 1352 into the wire slot 1352, so that the outer wall of the main wire 30 tightly fits the inner wall of the wire slot 1352 to form a good sealing effect.

[0038] In addition, the reinforcing rib 231 provided on the transition plate 23 also has a certain effect. The reinforcing rib 231 can strengthen the strength of the transition plate 23, so that the curved connecting piece 24 and other structures at the front of the transition plate 23 can maintain a certain pressing force on the front structure of the bottom shell 10.

[0039] Because the front wall of the box structure 131 has a protruding structure 1331 corresponding to the position near the top of the wire slot 1352, the enclosing angle of the wire slot 1352 with respect to the front wall of the box structure 131 is not less than 225°, and the front wire pressing plate 261 can be clamped by the two protruding structures 1331, so that a certain seal is formed around the main wire 30 at this position. The matching plate 242 is inserted into the sealing slot 1351, and the outer wall of the matching plate 242 tightly fits the inner wall of the sealing slot 1351 at the matching position, also forming a good sealing effect. Therefore, multiple sealing structures are provided on the channel through which the main wire 30 enters the inside of the wire clamp, so that it is difficult for external liquid to enter the wire connection structure.
