Description

Technical Field

[0001] The present application relates to the field of blasting technology, and in particular to an electronic detonator junction box. 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, 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 in the upper box body and the lower box body. The junction box that is waterproof by setting sealing rings in both the upper box body and the lower box body needs to install sealing rings in both the upper box body and the lower box body, and the whole assembly operation is troublesome and the cost is high; in addition, if the two sealing rings of the upper box body and the lower box body are not flat during installation, or there are assembly errors and other factors, the junction box will not be sealed tightly and the waterproof and dustproof performance will be poor; 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 that is filled with silicone grease to cover the reed, 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.

[0010] In some embodiments, two groups of slots for clamping the detonating busbar are provided at the bottom of the annular convex wall.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1 to Figure 6 As shown; an embodiment of the present application discloses an electronic detonator junction box, which is used for connecting the electronic detonator detonating busbar 3 and the leg wire. In this embodiment, the structure of the 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 other end is snap-connected; after the detonating busbar 3 and the leg wire are connected in the lower box body 1, the upper box body 2 is rotated to make the upper box body 2 and the lower box body 1 snap-connected and closed. Among them, one end of the upper box body 2 and the lower box body 1 are rotatably connected, which means that a rotating shaft 110 or a slot hole 209 is provided on the upper box body 2, and a slot hole 209 or a rotating shaft 110 is provided on the lower box body 1, and the rotating connection of the upper box body 2 and the lower box body 1 is realized by the rotational cooperation of the rotating shaft 110 and the slot hole 209; specifically in the present embodiment, one end of the lower box body 1 is fixedly connected with the rotating shaft 110, and one end of the body is provided with two coaxial slot holes 209; of course, in order to realize automated assembly, the rotating shaft 110 of the upper box body 2 and the slot hole 209 of the lower box body 1 are arranged to be assembled by mechanized equipment, for example, the bottom of the two slot holes 209 is provided with an introduction inclined surface 210 for the two ends of the rotating shaft 110 to be inserted into the slot hole 209 to facilitate the rotating shaft 110 to be inserted into the slot hole 209 by mechanized equipment, so that the assembly of the upper box body 2 and the lower box body 1 is simpler, more convenient and faster.

[0030] Furthermore, the other ends of the upper box body 2 and the lower box body 1 are snap-fitted, which means that two snap holes 109 are provided at one end of the lower box body 1 away from the rotating shaft 110, and an elastic plug-in portion is provided at one end of the upper box body 2 away from the slot 209, the elastic plug-in portion can be elastically deformed along the longitudinal direction of the upper box body 2 and quickly reset, and two convex snap-in blocks 208 are provided on the elastic plug-in portion, which are elastically snap-fitted with the two snap-in holes 109 respectively. When connected, the elastic plug-in portion is accommodated in the lower box body 1, and when the elastic plug-in portion is plugged in place, the two snap-in blocks 208 on the elastic plug-in portion are snap-fitted in the two snap-in holes 109. This arrangement improves the overall stability, pressure resistance and drop resistance of the junction box, and is safer.

[0031] In this embodiment, if Figure 3 , Figure 4 and Figure 5As shown, a fixing area 100 is provided in the lower box body 1, and the fixing area 100 is used for the area where the detonating bus 3 and the foot line are connected or the area where the two are fixed, and the fixing area 100 is substantially located at the central part of the bottom of the lower box body 1; two conductive wire cards 5 for connecting the detonating bus 3 and the foot line are connected in the fixing area 100, and the conductive wire cards 5 are arranged in a rectangular shape and are metal conductive parts, which have two groups of opposite walls, one group of opposite walls is provided with a bus bar hole for the detonating bus 3 to pass through, and the other group of opposite walls is provided with a foot line hole for the foot line to pass through; two crimping seats 200 corresponding to the two conductive wire cards 5 are connected to the upper box body 2, and the detonating bus 3 and the foot line in the two conductive wire cards 5 can be crimped 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 line are respectively connected to the conductive wire cards 5.

[0032] It is not difficult to understand that the detonating busbar 3 and the split leg wires both have an insulating cortex 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 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 cortex, 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.

[0033] For example, Figure 4 As shown, two groups of detonating busbars 3 and one group of leg wires are arranged in the electronic detonator junction box. The two groups of detonating busbars 3 are respectively inserted into two conductive wire cards 5, and both groups of detonating busbars 3 extend out of the junction box. Two split leg wires are arranged in one group of leg wires, and the two split leg wires are respectively connected to the leg wire holes of the two conductive wire cards 5, and the leg wires extend out of the junction box as a whole.

[0034] In order to be able to be used normally in wet and dusty environments such as rainy days, rivers, lakes, etc., the electronic detonator junction box has high requirements for its waterproof and dustproof performance. Figure 4 , Figure 5 and Figure 6As shown, in order to improve the waterproof and dustproof performance of the junction box, an annular gap 101 is formed between the fixed area 100 in the lower box body 1 and the inner wall of the lower box body 1, and the annular gap 101 surrounds the entire fixed area 100, and a soft elastic annular sealing body 6 is connected in the annular gap 101; an annular convex wall 201 arranged around two crimping seats 200 and extending along the thickness direction of the upper box body 2 is connected in the upper box body 2; when the upper box body 2 and the lower box body 1 are closed, the bottom edge of the annular convex wall 201 is crimped and sealed with the annular sealing body 6. Therefore, after the upper box body 2 is closed, the bottom of the annular convex wall 201 squeezes the soft annular sealing body 6, so that the top of the annular sealing body 6 elastically deforms downward and forms a sealed waterproof and dustproof structure with the bottom of the annular convex wall 201. Therefore, the sealing structure of the electronic detonator junction box is simple. The annular sealing body 6 is arranged on one side of the junction box, that is, in the lower box body 1, which saves materials and reduces production costs. Moreover, when the annular sealing body 6 is assembled, the assembly operation is simple and convenient, and the assembly efficiency is high. In addition, the annular sealing body 6 is generally made of rubber or silicone. Therefore, the crimping force between the hard material of the annular convex wall 201 and the soft material of the annular sealing body 6 can be set to be larger, so that the junction box has good waterproof and dustproof performance, can completely block water and dust from entering, and effectively prevent short circuit. It can not only be used normally in humid and dusty environments such as rainy days, rivers, lakes, etc., but also can meet the waterproof technical requirements of deep water areas, such as detonation at a depth of more than 1 meter underwater.

[0035] It is foreseeable that the bottom of the annular convex wall 201 is pressed onto the detonating busbar 3 , so two groups of clamping grooves 205 for clamping the detonating busbar 3 are provided at the bottom of the annular convex wall 201 to facilitate the detonating busbar 3 to pass through.

[0036] Further in this embodiment, Figure 3 and Figure 4 As shown, the annular sealing body 6 is an annular sealing ring installed in the annular gap 101. The annular sealing ring can be molded according to the shape and size of the annular gap 101 to obtain a finished annular sealing ring, which is then tightly fitted in the annular gap 101 by means of equipment press-fitting or manual installation. The annular sealing body 6 is only installed in the lower box body 1, so the installation process is simple and the operation is convenient.

[0037] In other embodiments, the annular sealing body 6 may also be an annular sealing ring that is secondary injection molded in the annular gap 101. In this way, the installation of the annular sealing body 6 only requires secondary injection molding on mechanical equipment. The process accuracy of the secondary injection molding is higher than the assembly accuracy, and the produced products are of good quality, without assembly defects, and the sealing performance is better than that of assembly.

[0038] In other embodiments, the annular sealing body 6 may also be a soft sealing silicone poured into the annular gap 101. 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 101. After the silicone material cools, an elastic and soft annular sealing body 6 is formed. When the annular convex wall 201 is separated from the soft sealing silicone, the sealing silicone does not adhere and can be used multiple times.

[0039] Further in this embodiment, Figure 4 and Figure 5 As shown, a fixing seat 102 is connected in the fixing area 100, and the fixing seat 102 forms two fixed grooves 106 arranged at intervals, and two conductive wire clips 5 are connected in the two fixed grooves 106. Specifically in this embodiment, the fixing seat 102 and the lower box body 1 are an integral injection molding structure; two side walls of the lower box body 1 are provided with two groups of bus ducts 103 that are connected to the inside of the lower box body 1 and for two groups of detonating busbars 3 to pass through, and the fixing seat 102 is provided with two groups of wire grooves 105 corresponding to the two groups of bus ducts 103. The bus duct 103 and the wire groove 105 are provided for the purpose of passing through the detonating busbar 3 on the one hand, and for the detonating busbar 3 to be clamped and positioned on the other hand, so that its connection structure is more stable and firm.

[0040] In order to further securely fix the detonating busbar 3, Figure 6 As shown, two pressing plates 202 corresponding to two crimping seats 200 are connected to the annular convex wall 201 of the upper box body 2, and the two pressing plates 202 are respectively arranged corresponding to the two groups of detonating busbars 3, and the bottom of each pressing plate 202 is provided with a pressing groove 203 for the detonating busbar 3 to pass through. In this way, after the upper box body 2 is closed, the pressing grooves 203 on the two pressing plates 202 are respectively crimped on the two groups of detonating busbars 3, so that the positioning of the detonating busbar 3 is more secure, and the detonating busbar 3 is prevented from falling off or loosening due to pulling.

[0041] The connecting end of the foot wire is arranged in the junction box, and the other end of the foot wire passes outward through the foot wire groove 104 at the front end of the lower box body 1 for the foot wire to pass through and is connected to the electronic detonator. In order to prevent the foot wire from falling off, in addition to the foot wire and the conductive wire clamp 5 being clamped and fixed, in the embodiment of the present application, Figure 4 and Figure 6 As shown, at least one pressing plate 204 extending from the bottom of the crimping seat 200 for crimping the foot line is provided in the annular convex wall 201 on one side of the crimping seat 200. After the upper box body 2 is closed, the free end of the pressing plate 204 is crimped to the inner end of the split foot line to fix or position the split foot line, thereby making the connection of the foot line more firm and stable.

[0042] In the embodiment of the present application, a partition 107 for separating the foot line is provided on one side of the lower box body 1 close to the foot line groove 104; that is, two grooves are provided on the partition 107, and the two split foot lines of the foot line pass through the two grooves on the partition 107 respectively; a crimping plate 206 is provided at the front end of the upper box body 2 to cooperate with the partition 107 to crimp the foot line, and a crimping groove 207 for the foot line to pass through is provided at the bottom of the crimping plate 206, such as Figure 4 As shown, after the upper box body 2 and the lower box body 1 are closed, the crimping plate 206 is located outside the partition 107, the crimping plate 206 and the partition 107 are staggered, and the crimping groove 207 on the crimping plate 206 is crimped on the foot line. This arrangement makes the positioning of the foot line more firm and stable.

[0043] In some embodiments, Figure 1 As shown, both sides of the front end of the lower box body 1 are provided with recesses 108 for hand holding. When opening or closing the upper box body 2, the recesses 108 are convenient for users to hold, making the operation of opening or closing the junction box more convenient.
