[0029] In order to make the purpose, technical solution and advantages of this technical solution more clear, the following technical solution is further described in detail in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of this technical solution.

[0030] Example 1

[0031] In order to solve the problem of limited waterproof capability of detonator terminal clamp in the prior art, Figure 1 As shown, this embodiment provides a detonator waterproof wire clamp with a labyrinth waterproof structure, which includes a base 10 and an upper cover 20 , and a sealant 30 is located at the fitting position between the base 10 and the upper cover 20 .

[0032] like Figure 2 As shown, in this embodiment, the base 10 includes a bottom plate and an outer periphery. The outer peripheral plate 11 is located on the top surface of the bottom plate. The middle part of the outer peripheral plate 11 has a partition 13 arranged along the width direction of the base 10. The partition 13 divides the cavity enclosed inside the outer peripheral plate 11 into a front cavity 16 and a rear cavity. There are four island structures and they are arranged in the rear cavity. The four island structures are arranged in a field shape. The island structures and the outer peripheral plate 11 are spaced apart, and there are also gaps between the four island structures. The two diagonal island structures are wiring positions, that is, Figure 1 The upper left and lower right island structures are wiring locations. In this embodiment, first wire inlets 111 are provided on both side panels 21 of the peripheral plate 11, corresponding to the wiring locations. A second wire inlet 113 is provided on the front side panel 21 of the peripheral plate 11. Wiring grooves are also provided on the partition 13, corresponding to the two rows of island structures. In this embodiment, an annular metal sheet 14 is placed in the wiring locations of the upper left and lower right island structures, and a wiring port 141 is provided on the annular metal sheet 14.

[0033] In this embodiment, sealant 30 is filled in the cross space between the peripheral plate 11 and the island structure, and between each island. The sealant 30 corresponds to the first wire inlet 111, the wire threading groove on the partition 13, and the wiring port 141 on the annular metal sheet 14, and is provided with a groove structure to facilitate the placement and positioning of the wires.

[0034] In the front cavity 16, the inner wall of the front side plate 21 of the outer peripheral plate 11 is provided with two first clamping structures 112, which are respectively located on the left and right sides of the second wire inlet 113. A lower hollow 114 is formed at the connection between the front side plate 21 and the bottom plate of the outer peripheral plate 11, and the position of the lower hollow 114 is vertically opposite to the first clamping structure 112.

[0035] In this embodiment, a split type rotating shaft 12 is arranged at the tail of the base 10, which is used to cooperate with the upper cover 20 to form a hinged connection.

[0036] As shown in Figure 3 In this embodiment, the main structure of the upper cover 20 is an inner peripheral plate 22, and side plates 21 are arranged on the left and right sides of the inner peripheral plate 22. The side plates 21 are spaced apart from the left and right side walls of the inner peripheral plate 22. Two wire pressing blocks 24 are arranged inside the inner peripheral plate 22, and the two wire pressing blocks 24 are respectively arranged at the lower left and upper right of the inner peripheral plate 22. The inner peripheral plate 22 is provided with a fourth wire inlet 221 in the corresponding width direction and length direction, and the side plate 21 is provided with a third wire inlet 211 at the position corresponding to the fourth wire inlet 221. A cross-shaped pressing plate structure is arranged in the middle of the inner peripheral plate 22 corresponding to the cross-shaped space of the base 10. In the length direction of the upper cover 20, a wire pressing structure plate 241 is arranged between the wire pressing block 24 and the inner peripheral plate 22.

[0037] In this embodiment, an ear plate 23 is arranged at the tail of the upper cover 20, and a rotating shaft connecting hole 231 is formed in the ear plate 23. The base 10 and the upper cover 20 are hinged by means of the rotating shaft 12 being fitted into the rotating shaft connecting hole 231.

[0038] A transition structure 25 is arranged at the front of the inner peripheral plate 22, and a pressing structure 26 is arranged at the front of the transition structure 25. The pressing structure 26 and the transition structure 25 form an integrated "S" shape. A buckle 252 is arranged at the front of the transition structure 25, and the transition structure 25 has a hollow passage in the middle, which is a fifth wire inlet 251.

[0039] As shown in Figure 2 and Figure 3 When the base 10 and the upper cover 20 are connected by means of the rotating shaft 12 being fitted into the rotating shaft connecting hole 231, the base 10 and the upper cover 20 are hinged to each other and can be buckled by rotating.

[0040] After the base 10 and the upper cover 20 are buckled, the inner peripheral plate 22 of the upper cover 20 is inserted between the island structure and the outer peripheral plate 11, that is, the lower end edge of the inner peripheral plate 22 abuts against the top surface of the sealing glue 30, and the cross-shaped pressing plate structure abuts against the top surface of the sealing glue 30 at the cross-shaped space between the island structures. Therefore, the inner peripheral plate 22 and the sealing glue 30 form a waterproof structure.

[0041] Combine Figure 1 As shown, when the upper cover 20 and the base 10 are buckled together, the side panel 21 is in close contact with the side wall of the base 10. At this time, the first wire inlet 111 and the third wire inlet 211 are opposite to each other. If wires are introduced into the first wire inlet 111 and the third wire inlet 211, the edges of the first wire inlet 111 and the third wire inlet 211 tightly press the outer edges of the wires, thereby forming a waterproof sealing structure.

[0042] Since a pressing space 15 is formed inside the annular metal sheet 14 , when the upper cover 20 is buckled onto the base 10 , the pressing protrusion 24 is inserted into the pressing space 15 , thereby forming a sealing structure between the pressing protrusion 24 and the annular metal sheet 14 .

[0043] like Figure 2 As shown, when one line of wire enters the wire pressing space 15 through the first wire inlet 111 and the wiring port 141, and the other line of wire branches through the second wire inlet 113 and enters the wire threading groove on the partition 13 and the wiring port 141 on the annular metal sheet 14 to enter the wire pressing space 15, when the wire pressing protrusion 24 is pressed into the wire pressing space 15, since the wiring port 141 is provided on the annular metal sheet 14, the lowest position of the wiring port 141 is lower than the position of the top surface of the sealant 30, and the wires are bent at the inner edge of the sealant 30 when entering, and a seal is also formed between the sealant 30, the wires and the wire pressing protrusion 24.

[0044] The combination of the three aforementioned sealing structures creates a labyrinthine sealing structure where the wires are threaded, as the wires are bent by the sealant 30 and the wire-pressing protrusions 24. The other locations form a stable, quasi-annular sealing structure through the end face of the sealant 30 and the lower edge of the inner circumferential plate 22.

[0045] In this embodiment, a partition 13 is installed within the inner cavity of the outer peripheral plate 11 near the head of the base 10. This partition 13 divides the outer peripheral plate 11 into a front cavity 16 and a rear cavity. The wiring connection is located in the rear cavity. A connection structure is provided between the base 10 and the upper cover 20, located in the front cavity 16. A first snap-fit ​​structure 112 is provided at the front wall of the outer peripheral plate 11. The upper cover 20 also includes a snap-fit ​​structure located in front of the inner peripheral plate 22. This snap-fit ​​structure is inserted into the front cavity 16, and its snap 252 engages with the first snap-fit ​​structure 112. The snap-fit ​​mechanism has an S-shaped cross-section.

[0046] The snap mechanism, namely the transition structure 25 and the snap 252, are both located in the front cavity 16 of the base 10. The snap mechanism is externally concealed, making it difficult to damage by external forces. Furthermore, due to the presence of the pressing structure 26, pushing the pressing structure 26 elastically deforms the transition structure 25, allowing the snap 252 to disengage from the first engaging structure 112, making operation very convenient.

[0047] As preferred, the bottom plate of the base 10 has a lower hollow 114 corresponding to the position of the buckle 252 and the first clamping structure 112, when the push press structure 26 fails to make the buckle 252 disengage from the first clamping structure 112, the lever can be transmitted through the lower hollow 114 to force the buckle 252 to disengage from the first clamping structure 112, avoiding the failure of the conventional push press unlocking.

[0048] Embodiment 2

[0049] The main structure of the detonator connecting clamp in this embodiment is consistent with that in Embodiment 1, and the difference lies in the position change of the buckle structure and the first clamping structure 112.

[0050] As shown in Figure 4 and Figure 5 In this embodiment, the second clamping structure 131 is arranged on the front side wall surface of the partition plate 13, the rear part of the transition structure 25 has the buckle 252, the bottom plate of the base 10 has the lower hollow 114 corresponding to the buckle, and the top plate of the upper cover 20 has the upper hollow 27 corresponding to the buckle.

[0051] In this embodiment, the direction of the buckle mechanism and the second clamping structure 131 is changed, and the effect of the cooperation of the two is consistent with that of the buckle and the first clamping structure 112 in Embodiment 1. Meanwhile, the upper hollow 27 and the lower hollow 114 are arranged, which can further increase the space of the operating lever.

[0052] In addition, the buckle mechanism is closer to the rear sealing cavity and the related structure, the distance between the two is shortened, the force of the buckling of the upper cover 20 and the base 10 is increased, and the waterproof effect is increased.

[0053] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, many changes can be made in the specific implementation mode and application range, as long as these changes do not deviate from the concept of the present application, they all belong to the protection scope of the present application.
