Description

Technical Field

[0002] In the field of blasting, electronic detonators can be controlled by electronic control systems to achieve the purpose of controlling the blasting process, and finally detonate the electronic detonators through the detonator. Electronic detonators include foot wires, detonation busbars, control circuit boards with delay chips, ignition heads and detonators. When in use, the detonation busbars need to be connected to the foot wires through a junction box, and then the busbars are connected to the detonation device, so that the detonation signal is transmitted to the control circuit board through the busbars and foot wires, and the delay chip is used to delay the preset time, and then the control circuit board issues a detonation command according to the delay to achieve detonation control.

[0003] The junction box of the related art includes a box body composed of an upper box body and a lower box body, one end of the upper box body and the lower box body are hinged and the other end is connected by a snap; two fixed areas of the detonating busbar are arranged in the lower box body, and metal wiring clips are arranged in the two fixed areas. The two detonating busbars pass through the busbar opening on one side of the box body, are fixed by the wiring clips of the two fixed areas respectively, and then pass through the busbar opening on the other side of the box body. The front end of the lower box body has a foot line opening, and the foot lines are fixed by the wiring clips of the two fixed areas respectively and extend outward from the foot line opening. The working conditions of blasting are usually more complicated, such as rainy weather, deep pits with accumulated water, damp underground tunnels, underwater reefs, mountain caves, etc. Therefore, most of the junction boxes of the related art have a waterproof function to avoid the position where the electronic detonator foot line in the junction box connects to the detonating busbar may be flooded to form a short circuit, resulting in the blasting point being unable to detonate normally or other safety accidents.

[0004] The junction box of the above-mentioned related technology has the following defects in actual use: the waterproof structure of the junction box of the related technology is either to set an annular sealing ring in both the upper box body and the lower box body, and when the upper box body and the lower box body are closed, the sealing rings in the upper box body and the lower box body abut against each other to seal; or to achieve the waterproof purpose by filling silicone grease to cover the spring sheet in the upper box body and the lower box body. The above-mentioned junction box waterproofed by the sealing ring has only one or two layers of waterproof structure inside. If the annular sealing ring is not flat during installation, or there is an assembly error, or mud, sand and dust enter, etc., it often causes the junction box to be poorly sealed and poor in waterproof and dustproof performance; especially in deep water areas, due to the high water pressure, it is easy to cause water to enter the junction box and cause a short circuit; and the waterproof junction box by filling silicone grease to cover the spring sheet, the silicone grease is sticky during the filling process, which is inconvenient to operate, and the assembly efficiency is low, and it is not easy to operate and assemble.

[0027] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figure 1 to Figure 5 As shown; an embodiment of the present application discloses a waterproof electronic detonator junction box, which is used to connect the electronic detonator detonating busbar 3 and the leg wire 4. In this embodiment, the waterproof electronic detonator junction box includes an upper box body 2 and a lower box body 1, and one end of the upper box body 2 and the lower box body 1 can be rotatably connected, and the upper box body 2 and the lower box body 1 are clamped together by a snap structure; after the detonating busbar 3 and the leg wire 4 are connected to the lower box body 1, the upper box body 2 is rotated so that the upper box body 2 and the lower box body 1 are clamped together and closed by the snap structure. Among them, one end of the upper box body 2 and the lower box body 1 are rotatably connected. In the present embodiment, it means that a rotating shaft 102 or a rotating groove is provided on the upper box body 2, and a rotating groove or a rotating shaft 102 is provided on the lower box body 1, and the rotating connection between the upper box body 2 and the lower box body 1 is realized by the rotational cooperation between the rotating shaft 102 and the rotating groove; of course, in order to realize automated assembly, the rotating shaft 102 or the rotating groove of the upper box body 2 and the rotating groove or the rotating shaft 102 of the lower box body 1 are arranged to be a structure that can be assembled by mechanized equipment, such as the rotating groove is arranged to have an introduction port or an introduction groove to facilitate the insertion of the rotating shaft 102.

[0029] In this embodiment, if Figure 1 and Figure 3 As shown, two fixed seats 103 are arranged at intervals in the lower box body 1, and the two fixed seats 103 are independent of each other, and each fixed seat 103 is connected with a conductive wire card 5 for connecting the detonating bus 3 and the foot wire; the conductive wire card 5 is a conductive wire card 5 made of metal material, and the conductive wire card 5 is tightly fitted in the fixed seat 103, and each conductive wire card 5 is arranged in a rectangular shape, with two groups of opposite walls, one group of opposite walls is provided with a busbar hole for the detonating bus 3 to pass through, and the other group of opposite walls is provided with a foot wire hole for the foot wire to pass through; the upper box body 2 is provided with two crimping seats 200 corresponding to the two conductive wire cards 5 respectively, and the two crimping seats 200 connected to the upper box body 2 can crimp the detonating bus 3 and the foot wire in the two conductive wire cards 5 after the upper box body 2 and the lower box body 1 are closed, so that the wire core in the detonating bus 3 and the wire core in the foot wire are respectively connected to the conductive wire card 5.

[0030] For example, Figure 3 As shown, two groups of detonating busbars 3 and one group of leg wires are arranged in the waterproof electronic detonator junction box. The two groups of detonating busbars 3 are respectively inserted into two conductive wire clips 5, and both groups of detonating busbars 3 extend out of the junction box. Two branch leg wires are arranged in one group of leg wires, and the two branch leg wires are respectively connected to the leg wire holes of the two conductive wire clips 5, and the leg wires extend out of the junction box as a whole.

[0031] It is not difficult to understand that both the detonating busbar 3 and the branch leg wire have an insulating layer and a wire core. After the upper box body 2 is closed, under the crimping of the crimping seat 200, when the detonating busbar 3 and the branch leg wire are clamped on the conductive wire card 5, the busbar hole and the leg wire hole of the conductive wire card 5 will pierce the insulating layer, thereby making the wire core of the detonating busbar 3 and the wire core of the branch leg wire respectively conductive with the conductive wire card 5.

[0032] In order to be able to be used normally in wet and dusty environments such as rainy days, rivers, lakes, etc., the waterproof electronic detonator junction box has high requirements for its waterproof and dustproof performance. Figure 1 , Figure 2 and Figure 3 As shown, in order to improve the waterproof and dustproof performance of the junction box, first, the bottom shape of the upper box body 2 is set to match the top shape of the lower box body 1; when the upper box body 2 and the lower box body 1 are closed, the bottom of the upper box body 2 is sealed against the top of the lower box body 1; specifically in this embodiment, the upper box body 2 and the lower box body 1 are both set to be circular, and when the upper box body 2 and the lower box body 1 are closed, the bottom of the upper box body 2 is sealed and fits with the top of the lower box body 1. Of course, in this embodiment, since the detonating bus 3 needs to be led outward, four bus ducts 101 for the detonating bus 3 to pass through are provided on the lower box body 1, and each bus duct 101 passes through the top wall of the lower box body 1 and has an insertion port 110 formed on the top wall of the lower box body 1. The bottom of the upper box body 2 is provided with four inserts 201 respectively matched with the bus duct 101, and the bottom of the insert 201 is provided with a wire groove 204 for the detonating bus 3 to pass through. When the upper box body 2 and the lower box body 1 are closed, the four inserts 201 are respectively inserted into the corresponding bus duct 101 through the insertion port 110, and the shape of the insert 201 is adapted to the shape of the bus duct 101. In this way, after the upper box body 2 and the lower box body 1 are closed, a sealing structure is formed between the upper box body 2 and the lower box body 1.

[0033] Further in this embodiment, Figure 3 and Figure 4As shown, a first annular sealing groove 105 surrounding two fixing seats 103 is provided in the lower box body 1, and a first annular convex rib 202 adapted to be plugged into the first annular sealing groove 105 is connected to the upper box body 2; the outer edge of each fixing seat 103 in the lower box body 1 is provided with a second annular sealing groove 106 surrounding the fixing seat 103, and the outer edge of each crimping seat 200 in the upper box body 2 is provided with a second annular convex rib 205 surrounding the crimping seat 200 and adapted to be plugged into the second annular sealing groove 106; when the upper box body 2 and the lower box body 1 are closed, the first annular convex rib 202 of the upper box body 2 is plugged and sealed in the first annular sealing groove 105 of the lower box body 1, and the second annular convex rib 205 of the upper box body 2 is plugged and sealed in the second annular sealing groove 106 of the lower box body 1. Therefore, in this embodiment, the waterproof electronic detonator junction box has a triple waterproof structure. Specifically, when the upper box body 2 and the lower box body 1 are closed, the abutment seal between the bottom of the upper box body 2 and the top of the lower box body 1 is the first waterproof layer, the first annular rib 202 of the upper box body 2 is plugged and sealed in the first annular sealing groove 105 of the lower box body 1 to form a second waterproof layer, and the second annular rib 205 of the upper box body 2 is plugged and sealed in the second annular sealing groove 106 of the lower box body 1 to form a third waterproof layer; therefore, after the upper box body 2 and the lower box body 1 are closed, the waterproof electronic detonator junction box has good waterproof and dustproof performance, which can reach the waterproof and dustproof grade of IP68, can completely block the ingress of water and dust, effectively prevent short circuit, and can be used normally in humid and dusty environments such as rainy days, rivers, lakes, etc., especially can meet the waterproof technical requirements for detonation in deep water areas; in addition, the above-mentioned triple waterproof structure of the waterproof electronic detonator junction box can meet the requirements of automated assembly, thereby making the assembly efficiency high and the assembly operation convenient.

[0034] In the embodiments of the present application, Figure 3 , Figure 4 and Figure 5 As shown, two concentric annular walls 104 are connected to the lower box body 1, and a first annular sealing groove 105 is formed between the two annular walls 104, and a first lower annular sealing body 113 is connected in the first annular sealing groove 105; a first upper annular sealing body 203 is connected to the top of the first annular rib 202, and when the upper box body 2 and the lower box body 1 are closed, the first upper annular sealing body 203 and the first lower annular sealing body 113 are sealed against each other. Specifically, the first lower annular sealing body 113 is secondary injection molded on the bottom wall of the first annular sealing groove 105, and the first upper annular sealing body 203 is secondary injection molded on the top of the first annular rib 202; the first upper annular sealing body 203 extends outward from the top of the first annular rib 202. The first lower annular sealing body 113 and the first upper annular sealing body 203 are both obtained by heating injection molding using a vertical injection molding machine. This process has higher precision than assembly, and the product quality produced is good, there is no assembly defect, and the sealing performance is better than assembly.

[0035] Similarly, in other embodiments, the first lower annular seal 113 and the first upper annular seal 203 may be formed by separate molds, and then the first lower annular seal 113 and the first upper annular seal 203 may be installed in the lower box body 1 and the upper box body 2 respectively using a mechanized assembly setting.

[0036] Furthermore, if Figure 4 and Figure 5 As shown, in this embodiment, the outer edge of each fixing seat 103 is provided with an annular convex wall 112 surrounding the fixing seat 103, and a second annular sealing groove 106 is formed between the annular convex wall 112 and the fixing seat 103, and a second lower annular sealing body 107 is connected in the second annular sealing groove 106; a second upper annular sealing body 206 is connected to the top of the second annular convex rib 205, and when the upper box body 2 and the lower box body 1 are closed, the second upper annular sealing body 206 and the second lower annular sealing body 107 are sealed against each other. Specifically, the second lower annular sealing body 107 is secondary injection molded on the bottom wall of the second annular sealing groove 106, and the second upper annular sealing body 206 is secondary injection molded on the top of the second annular convex rib 205; the second upper annular sealing body 206 extends outward from the top of the second annular convex rib 205. The second lower annular seal 107 and the second upper annular seal 206 are both obtained by heating and injection molding using a vertical injection molding machine. This process has higher precision than assembly, produces products of good quality, does not have assembly defects, and has better sealing performance than assembly. In other embodiments, the second lower annular seal 107 and the second upper annular seal 206 can also be formed by a separate mold, and then the second lower annular seal 107 and the second upper annular seal 206 are respectively installed in the lower box body 1 and the upper box body 2 using a mechanized assembly setting.

[0037] It is not difficult to understand that in the above embodiment, the two annular walls 104 are provided with grooves for the detonating busbar 3 to pass through at the positions corresponding to the busbar duct 101. Similarly, the first lower annular sealing body 113 in the first annular sealing groove 105 between the two annular walls 104 is also provided with a groove for the detonating busbar 3 to pass through; and correspondingly, the first annular rib 202 on the upper box body 2 and the first upper annular sealing body 203 are provided with convex parts corresponding to the grooves. Further, the second lower annular sealing body 107 is provided with a convex part that matches the detonating busbar 3, and the second annular rib 205 and the second upper annular sealing body 206 are provided with concave parts corresponding to the convex parts. When the upper box body 2 and the lower box body 1 are closed, the first upper annular sealing body 203 is sealed and matched with the first lower annular sealing body 113, and the second upper annular sealing body 206 is sealed and matched with or matched with the second lower annular sealing body 107.

For example, there are three clamping blocks 111 and three clamping grooves 207, and the clamping design of three buckles can effectively improve the stability, pressure resistance and drop resistance of the junction box, and the safety is better.

[0039] In some embodiments, Figure 1 and Figure 3 As shown, the lower box body 1 is provided with a foot wire groove 100 for the foot wire to pass through, and the foot wire groove 100 passes through one of the clamping blocks 111. This arrangement ensures that the fixing of the foot wire is not affected by the upper box body 2, thereby achieving a better fixing effect of the foot wire.

[0040] In some embodiments, Figure 3 As shown, both ends of each annular convex wall 112 are provided with a wire clamping bracket 108, and each wire clamping bracket 108 is provided with a wire clamping groove 109 for clamping the detonating busbar 3.
