Description

Technical Field

[0001] The present application relates to the field of blasting technology, and in particular to a waterproof electronic detonator line card. Background Art

[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, detonating busbars, control circuit boards with delay chips, ignition heads and detonating powder, etc. When in use, the detonating busbars need to be connected to the foot wires through the line card, and then the busbars are connected to the detonating 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 wire card of the related art, also known as the junction box, has a structure including a box body and a cover body, one end of the box body and the cover body is hinged and the other end is connected by a snap; two fixed areas of the detonating busbar are arranged in the box body, and metal wiring cards 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 cards 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 box body has a foot line opening, and the foot lines are fixed by the wiring cards 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 wire cards of the related art have a waterproof function to avoid the position where the electronic detonator foot line in the wire card connects to the detonating busbar may be flooded and form a short circuit, resulting in the blasting point being unable to detonate normally or other safety accidents.

[0004] The wire card of the above-mentioned related technology has the following defects in actual use: the waterproof structure of the wire card of the related technology is either to set an annular sealing ring in both the box body and the cover body, and when the box body and the cover body are closed, the two sealing rings in the box body and the cover body abut against each other to seal; or to achieve the waterproof purpose by filling silicone grease in the box body and the cover body. If the annular sealing ring of the wire card waterproofed by the sealing ring is uneven during installation, or there is an assembly error, or mud, sand and dust enter, etc., it will often cause the wire card to be poorly sealed and have poor waterproof and dustproof performance; especially in deep water areas, due to the high water pressure, it is easy to cause water to enter the wire card and cause a short circuit; and for the waterproof wire card covered with silicone grease, 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.

Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[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 5As shown; the embodiment of the present application discloses a waterproof electronic detonator wire card, which is also called an electronic detonator junction box, and is used for connecting the electronic detonator detonating busbar 3 and the leg wire 4. In this embodiment, the waterproof electronic detonator wire card includes a cover body 2 and a box body 1, and one end of the cover body 2 and the box body 1 is hinged and the other end is connected by a buckle structure. After the detonating busbar 3 and the leg wire 4 are connected in the box body 1, the cover body 2 is rotated to make the cover body 2 and the box body 1 snap-locked and closed. Among them, one end of the cover body 2 and the box body 1 is rotatably connected, which means that a rotatably connected slot 100 and a rotating shaft 200 are set at one end of the cover body 2 and the box body 1, and the rotating shaft 200 can be assembled into the slot 100 by mechanical equipment. In this way, in the assembly process of the cover body 2 and the box body 1, manual operation can be abandoned, and mechanical equipment can be used to replace manual assembly, thereby improving assembly efficiency; and the rotation matching structure of the slot 100 and the rotating shaft 200 has good stability.

[0029] For example, Figure 3 As shown, two oppositely arranged lugs 115 are fixedly connected at one end of the box body 1, and the two lugs 115 are provided with two coaxial slots 100; the two lugs 115 are respectively provided with vertical slots 101 connected to the slots 100, and one end of the slots 101 penetrates the outer side wall of the lugs 115; a rotating shaft 200 is fixedly connected at one end of the cover body 2, and the two ends of the rotating shaft 200 can be fitted in the two slots 100 through the slots 101. In this embodiment, the rotating shaft 200 and the cover body 2 are an integrally formed structure, and the slot 100 and the box body 1 are an integrally formed structure. In order to enable the two ends of the rotating shaft 200 to be quickly installed into the slot 100 through the vertical slots 101, in this embodiment, an introduction slope 102 can be provided at the insertion end of the slot 101 or / and the end of the rotating shaft 200.

[0030] In other embodiments, the rotating shaft 200 may be disposed at one end of the box body 1 , and the slot 100 may be disposed at one end of the cover body 2 .

[0031] In this embodiment, the cover body 2 and the other end of the box body 1 are connected by a snap-fit ​​structure. Figure 3 and Figure 4 As shown, the buckle structure includes two first clamping blocks 208 arranged on both sides of the front end of the cover body 2 and two second clamping blocks 103 arranged on the inner side wall of the front end of the box body 1. There is an elastic gap 207 between the two first clamping blocks 208 that can gather toward each other. When the cover body 2 is in a closed state, the two first clamping blocks 208 are elastically clamped on the two second clamping blocks 103. The clamping cooperation of the two groups of clamping blocks makes the clamping of the cover body 2 and the box body 1 more firm and stable, improves the overall stability, pressure resistance and drop resistance of the electronic detonator wire clamp, and improves safety.

[0032] Further, in this embodiment, two elastic gripping parts 210 that can be gathered toward each other are provided on both sides of the front end of the cover body 2, and each gripping part 210 is provided with anti-slip stripes, and an elastic gap 207 is provided between the two gripping parts 210 and the cover body 2, and the elastic gap 207 is a groove that runs through the top and bottom of the cover body 2, and the inner end of the groove is closed, and the outer end runs through the front end surface of the cover body 2. When the two gripping parts 210 are forced toward each other, the two gripping parts 210 can be elastically deformed and move toward each other; two elastic plates 209 are connected to the two gripping parts 210, and two first clamping blocks 208 are respectively connected to the two elastic plates 209. The first clamping block 208 is arranged on the elastic plate 209, so that the clamping of the first clamping block 208 and the second clamping block 103 is simpler, and when the clamping is released, the operation is also more labor-saving and convenient.

[0033] In the above embodiment, the front end of the box body 1 is provided with two insertion holes 104 corresponding to the two elastic plates 209, and the two second clamping blocks 103 are respectively connected to the inner wall above the two insertion holes 104. When the cover body 2 is in the closed state, the two elastic plates 209 are correspondingly inserted into the two insertion holes 104 and the first clamping blocks 208 on the two elastic plates 209 are clamped with the two second clamping blocks 103. This arrangement makes the clamping structure of the cover body 2 and the box body 1 more compact and stable.

[0034] In this embodiment, if Figure 3 As shown, first abutment surfaces 113 are provided on both sides of the top of the box body 1, and second abutment surfaces 201 corresponding to the first abutment surfaces 113 are provided on both sides of the bottom of the cover body 2, and when the cover body 2 is in a closed state, the second abutment surface 201 and the first abutment surface 113 are matched and sealed. The first abutting surface 113 is the top surface on both sides of the box body 1. In the present embodiment, the first abutting surface 113 is the top surface of the left wall of the box body 1 and the top surface of the right wall of the box body 1. Because the two sides of the box body 1 are provided with busbar ducts 110 for two groups of detonating busbars 3 to pass through, and the busbar ducts 110 are also located at the top of both sides of the box body 1, the first abutting surface 113 is tooth-shaped as a whole, and the second abutting surface 201 matched therewith is also tooth-shaped. After the cover body 2 is closed, the first abutting surface 113 and the second abutting surface 201 are engaged and sealed with each other; therefore, after the waterproof electronic detonator line is stuck in the cover body 2 and closed, a first waterproof and dustproof sealing structure is formed between the cover body 2 and the box body 1.

[0035] Further in the present embodiment, a fixing seat 105 is provided in the box body 1, and two conductive wire clips 5 for connecting the detonating busbar 3 and the foot wire 4 are connected in the fixing seat 105; specifically, two fixed grooves 109 arranged at intervals are provided in the fixing seat 105, and two conductive wire clips 5 are connected in the two fixing grooves 109; the conductive wire clips 5 are arranged in a rectangular shape, and are metal conductive components, which have two groups of opposite walls, one group of opposite walls is provided with a busbar hole for the detonating busbar 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; two crimping seats 202 corresponding to the two conductive wire clips 5 are connected to the cover body 2, and the detonating busbar 3 and the foot wire in the two conductive wire clips 5 can be crimped after the cover body 2 and the box body 1 are closed, so that the wire core in the detonating busbar 3 and the wire core in the foot wire are respectively conductive to the conductive wire clips 5.

[0036] It is not difficult to understand that the detonating busbar 3 and the split leg wires of the leg wire 4 both have an insulating layer and a wire core. After the cover body 2 is closed, under the crimping of the crimping seat 202, when the detonating busbar 3 and the split leg wires are clamped on the conductive wire card 5, the busbar holes and leg wire holes 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 split leg wire respectively conductive with the conductive wire card 5.

[0037] For example, Figure 3 As shown, two groups of detonating busbars 3 and a group of leg wires 4 are arranged in the waterproof electronic detonator wire card, the two groups of detonating busbars 3 are respectively inserted into the two conductive wire cards 5, and the two groups of detonating busbars 3 are extended out of the box body 1, and two split leg wires are arranged in one group of leg wires 4, and the two split leg wires are respectively connected to the leg wire holes of the two conductive wire cards 5, and the leg wire as a whole is extended out of the box body 1 through the leg wire groove 114 at the front end of the box body 1.

[0038] 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 line card has high requirements for its waterproof and dustproof performance. Figure 3 , Figure 4 and Figure 5As shown, in order to improve the waterproof and dustproof performance of the junction box, the fixing seat 105 in the box body 1 has an annular wall 106 that is closed on all sides. The annular wall 106 divides the fixing seat 105 into an independent space. An annular gap 107 is formed between the annular wall 106 and the inner circumferential wall of the box body 1, and a soft annular sealing body 108 is connected to the annular gap 107; an annular convex wall 203 that is arranged around two crimping seats 202 and extends along the thickness direction of the cover body 2 is connected to the cover body 2; when the cover body 2 and the box body 1 are closed, the annular convex wall 203 is embedded in the annular gap 107 and the bottom edge of the annular convex wall 203 is crimped and sealed with the annular sealing body 108. Therefore, after the cover body 2 is closed, the bottom of the annular convex wall 203 squeezes the soft annular sealing body 108, so that the top of the annular sealing body 108 elastically deforms downward and forms a second waterproof and dustproof sealing structure with the bottom of the annular convex wall 203. Therefore, the sealing structure of the waterproof electronic detonator line card is simple. The annular sealing body 108 is arranged on one side of the electronic detonator line card, that is, in the box body 1, which saves materials and reduces production costs. Moreover, when the annular sealing body 108 is assembled, the assembly operation is simple and convenient, and the assembly efficiency is high. In addition, the annular sealing body 108 is generally made of rubber or silicone. Therefore, the crimping force between the hard material of the annular convex wall 203 and the soft material of the annular sealing body 108 can be set to be larger, so that the waterproof and dustproof performance of the junction box is good, and the water and dust ingress can be completely blocked to effectively prevent short circuits. It can not only be used normally in humid and dusty environments such as rainy days, rivers, lakes, etc., but also meet the waterproof technical requirements for detonation in deep water areas, such as more than 1 meter underwater.

[0039] It can be foreseen that the bottom of the annular convex wall 203 is pressed onto the detonating busbar 3 , so two groups of clamping grooves for clamping the detonating busbar 3 are provided at the bottom of the annular convex wall 203 to facilitate the detonating busbar 3 to pass through.

[0040] Further in this embodiment, Figure 3 and Figure 4 As shown, the annular sealing body 108 is an annular sealing ring installed in the annular gap 107101. The annular sealing ring can be molded according to the shape and size of the annular gap 107 to obtain a finished annular sealing ring, which is then tightly fitted in the annular gap 107 by means of equipment press-fitting or manual installation. The annular sealing body 108 is only installed in the box body 1, so the installation process is simple and the operation is convenient.

[0041] In other embodiments, the annular sealing body 108 may also be an annular sealing ring that is secondary injection molded in the annular gap 107. In this way, the installation of the annular sealing body 108 only requires secondary injection molding on mechanical equipment. The process precision of the secondary injection molding is higher than the assembly precision, and the produced products are of good quality, without assembly defects, and the sealing performance is better than that of assembly.

[0042] In other embodiments, the annular sealing body 108 may also be a soft sealing silicone poured into the annular gap 107. The soft sealing silicone is a silicone material in the prior art. During the pouring process, the silicone material flows and fills the entire annular gap 107. After the silicone material cools, an elastic and soft annular sealing body 108 is formed. When the annular convex wall 203 is separated from the soft sealing silicone, the sealing silicone does not adhere and can be used multiple times.

[0043] In other embodiments, the bottom of the annular convex wall 203 is provided with a chamfered surface along the circumferential direction, so as to reduce the thickness of the bottom of the annular convex wall 203 from top to bottom. That is, the setting of the chamfered surface makes the thickness of the bottom of the annular convex wall 203 smaller than the thickness of the annular convex wall 203 itself, so that when the bottom of the annular convex wall 203 presses the annular sealing body 108, it is easier to compress the annular sealing body 108 downward, thereby making the pressure between the bottom of the annular convex wall 203 and the annular sealing body 108 greater and the sealing performance better.

[0044] In this embodiment, two groups of bus ducts 110 are provided on the two side walls of the box body 1, which are connected to the inside of the box body 1 and are provided for the two groups of detonating busbars 3 to pass through. Both side walls of the fixing seat 105 extend upwardly from the first abutting surface 113, and two groups of wire-passing grooves 111 are provided on the two side walls of the fixing seat 105, which correspond to the two groups of bus ducts 110. The bus ducts 110 and the wire-passing grooves 111 are provided for the passing of the detonating busbar 3 on the one hand, and for the positioning of the detonating busbar 3 on the other hand, so that the connection structure is more stable and firm.

[0045] Furthermore, since both side walls of the fixing seat 105 extend upwardly from the first abutting surface 113, after the cover body 2 is closed, the tops of the two side walls of the fixing seat 105 abut against the inner walls of the cover body 2 respectively, thereby enhancing the mechanical strength and pressure resistance of the electronic detonator wire card. In particular, a plurality of reinforcing ribs 112 are provided on the inner walls of the two side walls of the fixing seat 105, so the electronic detonator wire card has better anti-fall performance.

[0046] In order to further securely fix the detonating busbar 3 and the foot wire in the box body 1, Figure 3As shown, a wire pressing frame 205 surrounding the crimping seat 202 is connected around each crimping seat 202, and a gap is provided between the wire pressing frame 205 and the crimping seat 202; two opposite side walls of the wire pressing frame 205 are provided with a first crimping groove 206 for crimping the detonating busbar 3, and the other two opposite side walls of the wire pressing frame 205 are provided with a second crimping groove 207 for crimping the foot wire. The first crimping groove 206 of the wire pressing frame 205 can crimp the detonating busbar 3 on both sides of the conductive wire card 5, and the second crimping groove 207 of the wire pressing frame 205 can crimp the foot wire on both sides of the conductive wire card 5. After the cover body 2 is closed, the first crimping groove 206 and the second crimping groove 207 on the wire pressing frame 205 respectively press and fix the detonating busbar 3 and the foot wire, so that the positioning of the detonating busbar 3 and the foot wire is more secure, and the detonating busbar 3 or the foot wire is prevented from falling off or loosening due to pulling. In addition, the wire pressing frame 205 is arranged around the crimping seat 202. After the cover body 2 is closed, the two wire pressing frames 205 are sleeved on the two conductive wire cards 5, that is, the two wire pressing frames 205 independently separate the two conductive wire cards 5. In this way, the wire pressing frame 205 and the conductive wire card 5 form another sealed waterproof and dustproof structure, which can completely isolate water from entering the conductive wire card 5 even when used underwater with high water pressure.
