Description

Technical Field

[0001] The utility model relates to the technical field of wiring cards, and specifically relates to an electronic detonator wire card. Background Art

[0002] A wire card is a device for connecting the main network line without damage and insulating and protecting the parallel access points at the same time; common wire cards on the market usually include a bottom case and a top cover. There are wire clamping spring pieces for connecting wires in the bottom case, and the top cover is connected to the bottom case to insulate and protect the access points inside. One end of the top cover is usually hinged to the bottom case, and the other end is detachably clamped to the bottom case.

[0003] The clamping end of the wire card on the market is generally connected by a buckle. The buckle includes an upper buckle provided on the top cover and a lower buckle provided on the bottom case. The upper buckle is arranged in an M shape, and there are clamping holes on both side walls. There are clamping blocks on both side walls of the lower buckle, and the bottom case and the top cover are clamped by clamping the clamping blocks into the clamping holes, such as the buckle in the electronic detonator waterproof wire clip with the publication number CN220398378U and the name of electronic detonator waterproof wire clip. However, when this kind of wire card needs to be opened, it is necessary to apply an opposite pressure to the holding part at the lower end of the upper buckle, and the clamping block is separated from the clamping hole by squeezing the lower buckle, which requires the user to use a lot of strength to open, taking time and effort. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wire card that can easily open the top cover.

[0005] The technical solution of the utility model is to provide an electronic detonator wire card with the following structure:

[0006] It includes a bottom case and a top cover; one end of the top cover is hinged to the bottom case, and the other end is clamped to the bottom case; there are two elastic first clamping parts extending towards the bottom case and distributed at intervals at the clamping end of the top cover, and a second clamping part matching and clamping with the two first clamping parts is arranged at the clamping end of the bottom case; the free ends of the two first clamping parts are respectively connected with driving parts extending away from the bottom case and located outside the first clamping parts, which are used for when applying an opposite pressure to the free ends of the two driving parts, the connecting ends of the two driving parts drive the free ends of the two first clamping parts to open outwards so that the first clamping parts are separated from the second clamping parts.

[0007] After adopting the above structure, compared with the prior art, the electronic detonator wire card of the utility model has the following advantages:

[0008] The utility model provides a driving part extending outward at the free end of the first clamping part, and the user only needs to press the two driving parts in opposite directions to make the first clamping part disengage from the second clamping part, thereby completing the unlocking of the buckle; the driving part has the effect of a lever, which can make opening the top cover simpler and more labor-saving.

[0009] Preferably, the free ends of the two driving parts extend out of the top surface of the first clamping part in a direction away from the bottom shell, so that the driving part can be longer, which is similar to the effect of lengthening the lever, and is not only convenient to operate but also more labor-saving.

[0010] Preferably, a plurality of spaced-apart reinforcing ribs are connected between the connecting end of the driving portion and the free end of the first clamping portion, for linking the free end of the first clamping portion to open outward.

[0011] Preferably, both of the two first clamping parts are provided with clamping holes, and both side walls of the second clamping part are provided with clamping blocks, and the clamping blocks are clamped in the corresponding clamping holes; when the user presses the free ends of the driving parts in the opposite directions of the two driving parts, the free ends of the first clamping parts are turned outwards and the clamping blocks are disengaged from the clamping holes.

[0012] Preferably, the two first clamping parts and the two driving parts are integrally injection-molded and arranged in a W-shape, which can reduce the processing steps and save costs.

[0013] Preferably, the hinged end of the top cover is connected to a hinge shaft, the hinged end of the bottom shell is provided with two mounting holes adapted to the hinge shaft, and the hinged end of the bottom shell is provided with an introduction groove connected to the two mounting holes along the vertical direction on one side close to the top cover, and the two ends of the hinge shaft can be connected to the mounting holes via the introduction grooves.

[0014] After this arrangement, when assembling the top cover and the bottom shell, you only need to press the hinge shaft into the mounting hole from the guide groove, which is convenient for rapid assembly of automated equipment; in addition, the width of the guide groove should be slightly smaller than the outer diameter of the hinge shaft, so as to prevent the hinge shaft from falling out of the mounting hole.

[0015] Preferably, a wire-holding spring is provided in the bottom shell, and a wire-holding groove for the wire to pass through is provided on the wire-holding spring. The wire-holding groove extends upward along the height direction of the wire-holding spring and passes through the top of the wire-holding spring.

[0016] Preferably, the top of the wire clamping groove is arranged in a flared shape with a larger upper part and a smaller lower part; on both inner side walls of the wire clamping groove, there are protrusions extending into the wire clamping groove to prevent the wire from slipping out of the wire clamping groove. After the bus bar or leg wire is clamped into the wire clamping groove of the wire clamping spring piece, in some complex usage environments, the bus bar or leg wire is likely to pop out of the wire clamping groove, resulting in poor contact or functional failure. The protrusions on the inner side walls of the wire clamping groove play a blocking role and can restrict the bus bar or leg wire within the wire clamping groove. Brief Description of the Drawings

At the same time, the terms "first", "second", etc. are only used to distinguish the names of the components and do not have a primary and secondary relationship, and therefore should not be construed as a limitation to the present utility model.

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown; The present utility model discloses an electronic detonator wire clip: comprising a bottom case 1 and a top cover 2; one end of the top cover 2 is hinged to the bottom case 1, and the other end is snap-connected to the bottom case 1.

[0028] The snap-connection end of the top cover 2 (the end snap-connected to the bottom case 1) is provided with two elastic first snap-connection portions 21 extending towards the bottom case 1 and spaced apart; the snap-connection end of the bottom case 1 is provided with a second snap-connection portion 11 that mates with the two first snap-connection portions 21 for snap-connection; the free ends of the two first snap-connection portions 21 are respectively connected to drive portions 22 extending away from the bottom case 1 and located outside the first snap-connection portions 21, for when applying an opposite pressure to the free ends of the two drive portions 22, the connection ends of the two drive portions 22 drive the free ends of the two first snap-connection portions 21 to open outwards so that the first snap-connection portions 21 disengage from the second snap-connection portion 11.

[0029] Both of the two first snap-connection portions 21 are provided with snap holes 211, and both side walls of the second snap-connection portion 11 are provided with snap blocks 111 corresponding to the snap holes 211 one by one, and the snap blocks 111 are snap-connected in the corresponding snap holes 211; when the user presses the free ends of the two drive portions 22 in the opposite direction of the two drive portions 22, the free ends of the first snap-connection portions 21 turn outwards, and the snap blocks 111 disengage from the snap holes 211.

[0030] The present utility model provides a drive portion 22 extending outwards at the free end of the first snap-connection portion 21. The user only needs to press the two drive portions 22 in the opposite direction to make the first snap-connection portion 21 disengage from the second snap-connection portion 11, thereby completing the unlocking of the snap; the drive portion 22 has the function of a lever, which can make the opening of the top cover 2 simpler and more labor-saving.

[0031] The free ends of the two drive portions 22 both extend out of the top surface of the first snap-connection portion 21 in the direction away from the bottom case 1, so that the drive portion 22 can be longer, similar to the effect of lengthening the lever length, which is not only convenient to operate but also more labor-saving.

[0032] A plurality of spaced-apart reinforcing ribs are connected between the connection end of the drive portion 22 and the free end of the first snap-connection portion 21 for driving the free end of the first snap-connection portion 21 to open outwards. The reinforcing ribs can also increase the strength of the drive portion 22 and extend the service life.

[0033] The two first snap-connection portions 21 and the two drive portions 22 are integrally injection-molded and are arranged in a W shape, which can reduce the processing procedures and save costs.

[0034] The hinged end of the top cover 2 (the end hinged to the bottom case 1) is connected with a hinge shaft 23. The hinged end of the bottom case 1 is provided with two mounting holes 12 adapted to the hinge shaft 23. And on the side of the hinged end of the bottom case 1 close to the top cover 2, a guiding groove 121 communicating with the two mounting holes 12 is provided in the vertical direction. The two ends of the hinge shaft 23 can be connected in the mounting holes 12 through the guiding groove 121.

[0035] After such a setting, when assembling the top cover 2 and the bottom case 1, it is only necessary to press the hinge shaft 23 into the mounting hole 12 from the guiding groove 121, which is convenient for the automatic equipment to assemble quickly. In addition, the width dimension of the guiding groove 121 is slightly smaller than the outer diameter dimension of the hinge shaft 23 (the bottom case 1 is a plastic part and has a certain elastic deformation ability, and it can be pressed in hard during assembly), so as to prevent the hinge shaft 23 from disengaging from the mounting hole 12.

[0036] A wire clamping spring piece 3 is arranged in the bottom case 1. The wire clamping spring piece 3 is provided with a wire clamping groove 31 for the wire to pass through. The wire clamping groove 31 extends upward along the height direction of the wire clamping spring piece 3 and penetrates through the top of the wire clamping spring piece 3.

[0037] The top of the wire clamping groove 31 is arranged in a flared shape with a larger top and a smaller bottom, which is convenient for the wire to pass through. On the two inner side walls of the wire clamping groove 31, there are protrusions 32 extending into the wire clamping groove 31 for preventing the wire from disengaging from the wire clamping groove 31. After the bus bar or the leg wire (i.e., the wire) is clamped into the wire clamping groove 31 of the wire clamping spring piece 3, in some complex use environments, it is easy to pop out from the wire clamping groove 31, resulting in poor contact or functional failure. The protrusions 32 on the inner side wall of the wire clamping groove 31 have a blocking effect and can limit the bus bar or the leg wire in the wire clamping groove 31.

[0038] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
