The embodiment of the application provides a cable box conductor connecting structure.
Referring to fig. 1 to 5, in one embodiment, the cable box conductor connection structure 800 includes a cable 100, a housing 200, a rotating component 300, and a conductive component 400. Specifically, the housing 200 includes an upper case 210 and a lower case 220, and the upper case 210 and the lower case 220 are spliced up and down to form a hollow installation cavity 230. The rotating assembly 300 comprises a rotating shaft 310 and a rotating disc 320 coaxially sleeved on the rotating shaft 310, the rotating shaft 310 is convexly arranged on the bottom surface of the inner wall of the lower shell 220, the cable 100 is coiled on the outer peripheral surface of the rotating disc 320, and the cable 100 drives the rotating disc 320 to axially rotate relative to the rotating shaft 310 when being pulled or wound. The conductive assembly 400 includes a plurality of conductive strips 410, a plurality of conductive elastic wires 420, and a plurality of conductive rings 430; the conductive sheet 410 is disposed beside the turntable 320; the conductive ring 430 is fixedly arranged on the turntable 320 and is coaxially arranged with the rotating shaft 310; one end of the cable 100 extends into the turntable 320 and is electrically connected with the conductive ring 430; one end of the conductive elastic wire 420 is connected with the conductive sheet 410, and the other end of the conductive elastic wire 420 is elastically contacted with the outer ring surface of the conductive ring 430; when the conductive ring 430 rotates with the turntable 320, the conductive spring wire 420 and the conductive ring 430 always keep the wire in contact with the surface; one conductive tab 410, one conductive spring wire 420, and one conductive ring 430 are in one-to-one communication to form a conductive path that is electrically connected to the cable 100.
It should be noted that, the cable box conductor connection structure 800 is a part of a merchandise anti-theft security display device, and is mainly used for accommodating, winding up, pulling wires, implementing conductive paths, etc. of the cable 100. Here, the conductive path is a part of an anti-theft current loop, one end of the cable 100 extending out of the housing 200 is connected with the anti-theft connector 700, the conductive sheet 410 can be externally connected with an anti-theft alarm, i.e. current can flow into the anti-theft alarm sequentially through the anti-theft connector 700, the cable 100, the conductive ring 430, the conductive elastic wire 420 and the conductive sheet 410 to form an anti-theft current loop, so that the functions of anti-theft alarm and cable 100 storage are simultaneously realized.
Based on this design, in the present embodiment, by providing the rotation shaft 310, the turntable 320 around which the cable 100 is wound, and the like in the housing 200, free wire drawing and wire winding of the cable 100 can be achieved; at the same time, one end of the cable 100 is electrically connected to the conductive ring 430 by extending into the interior of the turntable 320, and is further electrically connected to the conductive wire 420 and the conductive sheet 410 to form a conductive path. Thus, when the cable 100 is wound or pulled to drive the turntable 320 to rotate, the continuous conductive connection from the external conductive sheet 410 to the cable 100 can be realized, i.e. the conductive connection and the free winding and pulling can be simultaneously realized. In particular, in the technical solution of the present application, since the conductive ring 430 and the conductive sheet 410 are electrically connected by the elongated conductive elastic wire 420, when the conductive ring 430 rotates along with the turntable 320, the conductive elastic wire 420 and the conductive ring 430 always keep the wire-to-surface conductive contact, so that compared with the conventional conductive connection design of the turntable adopting the conductive elastic sheet contact plane rotation, the contact between the conductive elastic wire 420 and the outer ring surface of the conductive ring 430 is lighter but continuous, so that the friction force between the conductive elastic wire 420 and the outer ring surface of the conductive ring 430 is smaller, and the turntable 320 is not easy to wear, thereby making the cable box conductor connection structure 800 more durable. In addition, through the coaxial design of the conductive ring 430, the turntable 320 and the rotating shaft 310, the conductive sheet 410 is arranged beside the turntable 320, and the conductive sheet 410 and the conductive ring 430 are connected through the conductive elastic wire 420, so that the wire-drawing box conductor connection structure 800 is simpler and more compact, and can effectively reduce the volume and the cost.
Referring to fig. 2 to 4, in the embodiment, the turntable 320 includes an upper turntable 321 and a lower turntable 322 that are spliced up and down, and the upper turntable 321 includes a first turntable body 321a and a first turntable flange 321b formed to extend radially from an outer edge of the first turntable body 321 a; the lower turntable 322 includes a second turntable body 322a and a second turntable flange 322b formed to extend radially from an outer edge of the second turntable body 322 a; the first and second dial bodies 321a and 322a and the first and second dial flanges 321b and 322b enclose a winding groove 323 in which the cable 100 is wound. The first rotating disc body 321a is provided with a first central shaft 324 protruding upwards, a plurality of conductive rings 430 are sleeved on the first central shaft 324 along the up-down axial direction, and the first central shaft 324 is provided with a first through hole 325 penetrating along the up-down axial direction; the second turntable body 322a is provided with a second through hole 327 and a second cavity 326 with an upper opening, the second through hole 327 is positioned on the bottom surface of the second cavity 326, and the second through hole 327 is communicated with the second cavity 326; the rotating shaft 310 passes through the second through hole 327 and then extends into the first through hole 325. The rotating assembly 300 further includes a coil spring 330 built in the second receiving cavity 326, the coil spring 330 being built in the second receiving cavity 326, one end of the coil spring 330 being connected to the rotating shaft 310, the other end of the coil spring 330 being connected to the lower rotating disc 322. It can be understood that, in this integrated assembly mode of up-down splicing the upper turntable 321 and the lower turntable 322, on one hand, while ensuring that the conductive ring 430, the turntable 320 and the rotating shaft 310 can coaxially rotate, the occupied volume can be further reduced, which is beneficial to miniaturization; on the other hand, the assembly of the coil spring 330 and the conductive ring 430 is also facilitated. Here, the coil spring 330 is provided to ensure smooth and automatic winding up of the cable 100 after the cable 100 is pulled out, and the housing 200 is provided with the wire outlet 240 through which the cable 100 is extended. The first and second rotating disc flanges 321b and 322b may have an up-down limiting function, that is, the cable 100 is wound around the outer circumferential surfaces of the first and second rotating disc bodies 321a and 322a and is also accommodated in the winding groove 323, so that the cable is not dislocated up and down. The volume of the winding groove 323 can be specifically set according to the length and thickness of the cable 100, and the outer edges of the first rotating disc flange 321b and the second rotating disc flange 322b are adjacent to the inner side wall of the housing 200 as much as possible but have a gap, so that the volume of the conductor connecting structure 800 of the cable box can be reduced as much as possible, and meanwhile, the rotating of the rotating disc 320 and the winding of the cable are not influenced. Of course, to facilitate rotation of the turntable 320, a gap is formed between the rotation shaft 310 and the inner walls of the first through hole 325 and the second through hole 327.
Referring to fig. 3 to 5, in the present embodiment, an outer ring surface of the conductive ring 430 is disposed with a concave arc surface. Specifically, the conductive ring 430 is made of a conductive material, such as, but not limited to, a metallic material with good conductivity, etc. Here, the concave arc surface is not only beneficial to further reducing the friction force between the conductive ring 430 and the conductive elastic wire 420, but also plays a certain role of up-down limiting through the inward concave shape, so as to prevent the conductive elastic wire 420 from moving up and down in a dislocation manner, thereby causing the disorder of the conductive path. Of course, in other embodiments, the outer ring surface of the conductive ring may be disposed in other forms, which is not particularly limited herein.
Further, the number of the conductive rings 430 is plural, the conductive assembly 400 further includes a separation sheet 510 sleeved on the first central shaft 324, and a separation sheet 510 is disposed between two adjacent conductive rings 430. In particular, in this embodiment, as shown in fig. 3, since the cable 100 has two wire cores 110 to respectively realize the functions of charging and transmitting the anti-theft alarm signal, the number of the conductive paths is two, and accordingly, the number of the conductive rings 430 is two, the two conductive rings are isolated by one separating sheet 510, and the number of the conductive elastic wires 420 and the conductive sheets 410 is also two. Of course, in other embodiments, the number of conductive paths may be selected according to practical needs, that is, the number of conductive rings may be one or more than two, and the number of conductive elastic wires and conductive sheets is consistent with that of the conductive rings. Here, the separation sheet 510 should be made of an insulating material, and its outer diameter is preferably larger than that of the conductive ring 430, so as to perform a better isolation and limit function of preventing the conductive spring wire 420 from being dislocated up and down.

Further, the positioning cover 340 has a stopper flange 341 formed to extend radially from the outer peripheral surface, and the stopper flange 341 abuts against the tip of the uppermost conductive ring 430. Because the positioning cover 340 is in interference fit with the first through hole 325, the limiting flange 341 has a limiting effect on the uppermost conductive ring 430, and then cooperates with the limiting step 324a arranged on the outer peripheral surface of the first central shaft 324 to limit the lowermost conductive ring 430, so that the plurality of conductive rings 430 and the separating sheet 510 can be limited and fixed up and down, and falling off from the first central shaft 324 is avoided.

The conductive connection member may be made of a conductive material, such as a metal material, like the conductive ring 430, the conductive spring wire 420, and the conductive sheet 410, and the conductive connection member is provided to facilitate connection of the cable 100 to the conductive ring 430. In this embodiment, a scheme is adopted in which the wire core 110 is directly electrically connected to the conductive ring 430 in the cavity 324b, and for better fixing the wire core 110, the width of the first opening 324c may be slightly smaller than the wire diameter of the wire core 110.
