Description

Technical Field

[0001] This utility model relates to the technical field of electronic detonator lead wire and busbar connection device, and more specifically, to an electronic detonator lead wire clamp. Background Technology

[0002] An electronic detonator line clamp is a device used to electrically connect the leads of an electronic detonator to the detonating busbar. Currently, Chinese Patent Publication No. CN222869224U discloses a waterproof electronic detonator line clamp. In this case, the waterproof electronic detonator line clamp is pre-assembled onto the leads of the detonator; that is, the inner core wire of the lead on the detonator is pre-clamped onto the conductive spring in the waterproof electronic detonator line clamp. This means that if the electronic detonator line clamp malfunctions or is defective, or if the leads short-circuit and cannot connect, the entire set needs to be replaced. Discarding all detonators would result in a waste of electronic detonators and their wiring clips. Another issue is that even if on-site workers discover that the wiring clips on the finished electronic detonators are damaged, and even if there are spare clips available, special tools are required to install the inner core clip from the lead wire of the electronic detonator onto the conductive spring in the new electronic detonator wiring clip. However, these special tools are often not available on-site, making it difficult to connect the lead wires of the electronic detonator to the spare electronic detonator wiring clips. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electronic detonator line clamp, which has the advantages of convenient connection with the busbar and the lead wires on the electronic detonator, and can avoid the scrap loss of electronic detonators due to damage to the electronic detonator line clamp.

[0004] This utility model provides an electronic detonator wire clip, including a housing, a busbar cover, a lead wire cover, and two conductive springs. Both conductive springs are vertically fixed to the inside of the housing. The rear side of the busbar cover is hinged to the upper part of the rear side of the housing, and the rear side of the lead wire cover is hinged to the lower part of the rear side of the housing. When the busbar cover is closed to the upper end of the housing, it can press the two busbars to the upper end of one of the conductive springs, ensuring that the conductive core of each busbar is connected to the corresponding conductive spring. When the lead wire cover is closed to the lower end of the housing, it can press the two inner cores of the lead wires to the lower end of one of the conductive springs, ensuring that the conductive core of each inner core is connected to the corresponding conductive spring.

[0005] By adopting the above structure, this utility model ensures that each inner core wire in the lead wire is pressed onto the lower end of the corresponding conductive spring through the lead wire cover, so that the conductive core wire of each inner core wire is connected to the corresponding conductive spring. Furthermore, since the busbar is pressed onto the upper end of the corresponding conductive spring through the busbar cover, so that the conductive core of each busbar is connected to the corresponding conductive spring, when a damaged electronic detonator clamp is found on the construction site, workers can replace it with a spare electronic detonator clamp without the need for any tools. This facilitates the connection between the lead wire and the busbar of the electronic detonator and avoids the scrap loss of the electronic detonator due to damage to the electronic detonator clamp.

[0006] In one possible implementation, each conductive spring has a wire hole on its front and rear sidewalls at the bottom. Two inner core wires are respectively inserted into the two wire holes on one of the conductive springs. The upper edge of each wire hole is connected to a first wire-breaking groove arranged vertically. When the inner core wire is pushed from the wire hole into the first wire-breaking groove, the conductive core of the inner core wire is connected to the conductive spring. With this structure, when the inner core wire of the lead wire is inserted into the wire hole and pushed from the wire hole into the first wire-breaking groove, the sidewall of the first wire-breaking groove can cut through the wire sheath of the inner core wire to connect the conductive core of the inner core wire to the conductive spring, thus having the advantage of convenient electrical connection between the inner core wire and the conductive spring.

[0007] In one possible implementation, two insertion holes are provided on the side wall of the housing, and two inner core wires are respectively inserted into one of the insertion holes; the bottom of the housing is provided with through holes corresponding vertically to two conductive springs, and the lead wire cover is provided with two first crimping blocks corresponding to the through holes; when the lead wire cover is closed to the lower end of the housing, each first crimping block is used to pass through the corresponding through hole and be inserted into the corresponding conductive spring from bottom to top, and the first crimping block is used to push the inner core wire located in the wire hole into the first wire breaking groove; with this structure, the two inner core wires of the lead wire can be easily inserted into the corresponding conductive springs through the insertion holes. In the hole, and after the lead wire cover is closed onto the lower end of the box, each first crimping block can pass through the corresponding through hole and be inserted into the corresponding conductive spring from bottom to top. At this time, the first crimping block can push the inner core wire located in the wire hole into the first wire breaking groove, and the side wall of the first wire breaking groove can cut the wire insulation of the inner core wire so that the conductive core of the inner core wire is connected to the conductive spring. That is, by adopting the above structure, the inner core wire of the lead wire can achieve electrical connection with the conductive spring through crimping. In the process of crimping the inner core wire of the lead wire with the conductive spring, no tools are needed, which has the advantage of convenient crimping of the wire core of the lead wire with the conductive spring.

[0008] In one possible implementation, the inner walls on both sides of the connection between the lower end of the first wire-breaking groove and the wire hole are provided with arc surfaces. The arc surfaces are used to cooperate with the outer wall of the inner core wire for guidance so that the inner core wire can be inserted into the first wire-breaking groove. With this structure, under the action of the arc surfaces, during the process of the inner core wire being pressed into the first wire-breaking groove by the first pressing block, the outer wall of the inner core wire can cooperate with the arc surfaces for guidance so that the inner core wire can be inserted into the first wire-breaking groove more smoothly and achieve electrical connection with the conductive spring.

[0009] In one possible implementation, a first protrusion is provided on the lower part of the rear side of the box body, and two first connecting ears are provided on the rear side of the lead wire cover in a left-right symmetrical manner. The rear side of the lead wire cover is rotatably connected to the lower part of the rear side of the box body through a first pivot that passes through the first protrusion and the two first connecting ears. With this structure, the rear side of the lead wire cover can be reliably and conveniently rotatably connected to the lower part of the rear side of the box body under the cooperative action of the first protrusion, the first connecting ears and the first pivot.

[0010] In one possible implementation, each conductive spring has a second wire-breaking groove with an open top on its left and right sidewalls. The second wire-breaking groove extends vertically, and the busbar cover has two second crimping blocks corresponding to one of the conductive springs. When the busbar cover is closed to the top of the housing, each second crimping block is inserted into the corresponding conductive spring from top to bottom, and the second crimping block pushes the busbar at the corresponding position into the two second wire-breaking grooves on the corresponding conductive spring, so that the conductive core of the busbar is connected to the conductive spring. By adopting this structure, the two busbars are pre-clamped into the second wire-breaking grooves. In the open end of the wire breakage groove, and after the busbar cover is closed to the upper end of the box, each second crimping block can be inserted into the corresponding conductive spring from top to bottom. At this time, the second crimping block can push the busbar at the corresponding position into the two second wire breakage grooves on the corresponding conductive spring, and the side wall of the second wire breakage groove can cut the wire sheath of the busbar so that the conductive core of the busbar can be connected to the conductive spring. That is, by adopting the above structure, the busbar can be electrically connected to the conductive spring by crimping, and no tools are needed during the crimping process between the busbar and the conductive spring, which has the advantage of convenient crimping between the busbar and the conductive spring.

[0011] In one possible implementation, each of the inner walls on both sides of the upper opening of the second wire breakage groove is provided with an arc-shaped guide surface. The arc-shaped guide surface is used to cooperate with the outer wall of the busbar to guide it so that the busbar can be inserted into the second wire breakage groove. With this structure, under the action of the arc-shaped guide surface, during the process of the second pressing block pushing the busbar and pressing the busbar into the second wire breakage groove, the outer wall of the busbar can cooperate with the arc-shaped guide surface to guide it so that the busbar can be inserted into the second wire breakage groove more smoothly and achieve electrical connection with the conductive spring.

[0012] In one possible implementation, a second protrusion is provided on the upper part of the rear side of the box body, and two second connecting ears are provided on the rear side of the busbar cover in a left-right symmetrical manner. The rear side of the busbar cover is rotatably connected to the upper part of the rear side of the box body through a second rotating shaft passing through the second protrusion and the two second connecting ears. With this structure, the rear side of the busbar cover can be reliably and conveniently rotatably connected to the upper part of the rear side of the box body under the cooperative action of the second protrusion, the second connecting ears and the second rotating shaft.

[0022] See Figure 1-5 As shown, this application discloses an electronic detonator wire clip, including a housing 1, a busbar cover 2, a lead wire cover 3, and two conductive springs 4. Both conductive springs 4 are vertically fixed to the inside of the housing 1. The rear side of the busbar cover 2 is hinged to the upper part of the rear side of the housing 1, and the rear side of the lead wire cover 3 is hinged to the lower part of the rear side of the housing 1. When the busbar cover 2 is closed to the upper end of the housing 1, it can press two busbars 5 onto the upper end of one of the conductive springs 4, ensuring that the conductive core wire of each busbar 5 is connected to the corresponding conductive spring 4.

When the inner core wire 61 is pushed from the wire hole 41 into the first wire-breaking groove 42, the conductive core of the inner core wire 61 is connected to the conductive spring 4. With this structure, when the inner core wire of the lead wire is inserted into the wire hole, and when the inner core wire is pushed from the wire hole into the first wire-breaking groove, the sidewall of the first wire-breaking groove can cut the wire sheath of the inner core wire so that the conductive core of the inner core wire is connected to the conductive spring, which has the advantage of convenient electrical connection between the inner core wire and the conductive spring.

The first crimping block 31 is also used to push the inner core wire 61 located in the wire hole 41 into the first wire breaking groove 42. With this structure, the two inner core wires of the lead wire can be easily inserted through the insertion holes. After the lead wire cap is closed onto the lower end of the housing, each first crimping block can pass through the corresponding through hole and be inserted into the corresponding conductive spring from bottom to top. At this time, the first crimping block can push the inner core wire located in the wire hole into the first wire breaking groove, and the side wall of the first wire breaking groove can cut the wire sheath of the inner core wire so that the conductive core of the inner core wire is connected to the conductive spring. That is, by adopting the above structure, the inner core wire of the lead wire can be electrically connected to the conductive spring through crimping. In the process of crimping the inner core wire of the lead wire to the conductive spring, no tools are needed, which has the advantage of convenient crimping of the wire core of the lead wire to the conductive spring.

[0025] Both sides of the inner wall at the connection between the lower end of the first wire-breaking groove 42 and the wire hole 41 are provided with arc surfaces 43. The arc surfaces 43 are used to cooperate with the outer wall of the inner core wire 61 for guidance so that the inner core wire 61 can be inserted into the first wire-breaking groove 42. With this structure, under the action of the arc surfaces, during the process of the inner core wire being pressed into the first wire-breaking groove by the first pressing block, the outer wall of the inner core wire can cooperate with the arc surfaces for guidance so that the inner core wire can be inserted into the first wire-breaking groove. That is, the inner core wire can be inserted into the first wire-breaking groove more smoothly and achieve electrical connection with the conductive spring.

With this structure, the rear side of the lead wire cover can be reliably and conveniently rotatably connected to the lower part of the rear side of the box body under the cooperation of the first protrusion, the first connecting ears and the first rotating shaft.

[0027] Each conductive spring 4 has a second wire-breaking groove 44 with an open top on its left and right side walls. The second wire-breaking groove 44 extends vertically. The busbar cover 2 has two second crimping blocks 21 corresponding to one of the conductive springs 4. When the busbar cover 2 is closed to the top of the housing 1, each second crimping block 21 is inserted into the corresponding conductive spring 4 from top to bottom. The second crimping block 21 is used to push the busbar 5 at the corresponding position into the two second wire-breaking grooves 44 on the corresponding conductive spring 4, so that the conductive core wire of the busbar 5 is connected to the conductive spring 4. By adopting this structure, the two busbars are pre-... After the busbar cover is closed onto the upper part of the box, each second crimping block can be inserted into the corresponding conductive spring from top to bottom. At this time, the second crimping block can push the busbar at the corresponding position into the two second crimping slots on the corresponding conductive spring, and the side wall of the second crimping slot can cut the wire insulation of the busbar so that the conductive core of the busbar can be connected to the conductive spring. That is, by adopting the above structure, the busbar can be electrically connected to the conductive spring by crimping, and no tools are needed during the crimping process between the busbar and the conductive spring, which has the advantage of convenient crimping between the busbar and the conductive spring.
