Description

Technical Field

[0001] The utility model relates to the technology of conductive terminal field, in particular to a conductive terminal, a terminal continuous material strip and a power socket, which is mainly but not limited to a power strip product. Background Art

[0002] Conductive terminals are widely used, such as power strips commonly seen in daily life.

[0003] For example, CN 117498066 A discloses a two-hole copper piece for a power strip, including a two-hole copper piece module, the number of which is set to at least two, and the two two-hole copper piece modules are distributed along the left and right sides; the two-hole copper piece module includes a first copper piece and a second copper piece, which are distributed in sequence from front to back, and the left ends of the first copper piece and the second copper piece are both provided with an insertion sleeve or an insertion head, and the right ends of the first copper piece and the second copper piece are both provided with an insertion head or an insertion sleeve, and the insertion head of one of the two-hole copper piece modules is inserted into the insertion sleeve of the other two-hole copper piece module to form a contact fit. The first clamping end of the first copper piece and the second clamping end of the second copper piece are distributed along the front and back or left and right sides, and the clamping ends are both bent outward and extended laterally from the side of the copper sheet, and the left and right widths of the metal material are large, the material cost is high, and the structure is complex, and the production is troublesome.

[0004] For another example, CN 112003063 A discloses a single-row socket, which is equipped with at least one ten-hole base and / or at least one seven-hole base; the ten-hole base and the seven-hole base are both provided with a sleeve copper bar, and the sleeve copper bar is provided with an L-pole welding foot, an N-pole welding foot and an E-pole welding foot; the ten-hole base and the seven-hole base are both provided with an L-pole welding foot hole, an N-pole welding foot hole, and an E-pole welding foot hole; when several ten-hole bases and several seven-hole bases are installed in the same single-row socket, all the L-pole welding foot holes, N-pole welding foot holes, and E-pole welding foot holes are respectively on the same straight line, all the L-pole welding feet are welded to the same L-pole connecting copper bar, all the N-pole welding feet are welded to the same N-pole connecting copper bar, and all the E-pole welding feet are welded to the same E-pole connecting copper bar. As shown in the attached manual of CN112003063 A Fig. 9 As shown in the figure, these L-pole welding legs, N-pole welding legs and E-pole welding legs are all bent and extended outwards, and the left and right widths of the metal materials are large, and the material cost is high. Figure 6 As shown, although the weld leg is longitudinally bent and extended, the contact width of the clamping groove (directly related to the contact area) of this bending structure is still determined by the lateral extension dimension. Therefore, if the contact area needs to be guaranteed, the consumed plate width is still large and the material cost is still high.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] Please refer to Figures 1 to 9 As shown, it shows the specific structure of various embodiments of the present utility model.

[0033] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] A conductive terminal includes a substrate a1 and a side panel a2; the substrate a1 is extended forward and backward, and is usually provided with some positioning holes and / or process holes; one end of the side panel a2 is connected to one side of the substrate a1; the side panel a2 is extended forward and backward along the side edge of the substrate a1, and the side panel a2 maintains a distance from the substrate a1; the side panel a2 is provided with at least a first bend b1, a second bend b2 and a third bend b3 arranged at a distance along the front-to-back direction, the side panel a2 is bent outward at the first bend b1, and is bent inward at the second bend b2, and is bent inward at the third bend b3, so that: a U-shaped conductive clip c is bent on the side panel a2. The side panel a2 is further provided with a fourth bending portion b4, and the fourth bending portion b4 is located in front of the first bending portion b1, and the side panel a2 is bent upward or downward at the fourth bending portion b4.

[0035] In actual design, the side panels a2 are respectively connected to the left and right sides of the substrate a1, and more than two side panels a2 are arranged on the left or right side of the substrate a1 at intervals along the front-to-back direction, so that: the conductive terminal has multiple U-shaped conductive clips c.

[0036] Specifically, the side panel a2 includes a transverse extension portion a21 and a longitudinal extension portion a22; one end of the transverse extension portion a21 is integrally connected to one side of the substrate a1, and the other end of the transverse extension portion a21 extends outward away from the substrate a1; the front end of the longitudinal extension portion a22 is connected to the other end of the transverse extension portion a21, and the rear end of the longitudinal extension portion a22 extends backward beside the substrate a1; the first bending point b1, the second bending point b2 and the third bending point b3 are arranged on the longitudinal extension portion a22, and the fourth bending point b4 is arranged on the transverse extension portion a21. The substrate a1 and the side panel a2 are integrally punched and bent parts of the same metal plate; the plate thickness direction of the substrate a1 is the up-down direction; the plate thickness direction of the portion of the lateral extension portion a21 corresponding to the fourth bending point b4 close to one end of the lateral extension portion a21 is the up-down direction, that is: the thickness direction of the portion of the lateral extension portion a21 located between one end of the lateral extension portion a21 and the fourth bending point b4 is the up-down direction; after the side panel a2 is bent upward or downward at the fourth bending point b4, the plate thickness direction of the portion of the lateral extension portion a21 corresponding to the fourth bending point b4 away from one end of the lateral extension portion a21 is the left-right direction; therefore, the plate thickness direction of the conductive clip c is the defined horizontal direction. The longitudinal extension part a22 includes a longitudinal connection strip a221 and two clips a222; the front end of the longitudinal connection strip a221 is integrally connected to the other end of the transverse extension part a21, and the rear end of the longitudinal connection strip a221 extends backward from the side of the substrate a1; when not bent, the distance between the longitudinal connection strip a221 and the side of the substrate a1 is usually the left and right width of the transverse extension part a21; the clips a222 are integrally connected to the inner side of the longitudinal connection strip a221, and the two clips a222 maintain a front-to-back distance; after bending, the two clips a222 are arranged on opposite sides to form a clamping groove a223. In order to improve the reliability of clamping contact, usually, one of the clips a222 or the two clips a222 are contact springs protruding toward the clamping groove.

[0037] When not bent, the front-to-back length L1 of the clip a222 is greater than the left-right width L2. Sufficient dimensions in the front-to-back direction are used to design the front-to-back length L1 of the clip. Therefore, on a metal sheet with sufficiently narrow left-right width, the clip can still freely and flexibly set a sufficient front-to-back length to meet the contact area requirements and improve contact reliability.

[0038] It should be noted that the conductive terminal can adopt the side plate a2 structure described above on one side or both sides, such as Figure 1-6As shown, it shows an embodiment in which the side plate a2 structure described above is adopted on both sides. If the side plate a2 structure described above is designed only on one side of the substrate a1, the side plate a2 and the conductive clip may not be provided on the other side, or as shown in FIG. Figures 7 to 9 As shown, other structural forms of side panels a2' may be provided on the other side, which are not listed one by one in this article.

[0039] A terminal continuous material strip is provided. The aforementioned conductive terminal is usually produced and processed in the form of a terminal continuous material strip, and then the corresponding length is cut according to the number of groups of conductive clips c required. The terminal continuous material strip includes a plurality of conductive terminals connected in sequence along the length direction, and a cutting position K is preset between adjacent conductive terminals. The conductive terminal is a conductive terminal as described above.

[0040] And, a power socket is provided, which is provided with a conductive terminal as described in any of the above items. The power socket can refer to a socket with a single set of sockets, or a strip socket with multiple sets of sockets; it includes a shell and a conductive terminal arranged in the shell, and an external socket is reserved on the shell, and the external socket is arranged opposite to the slot of the conductive clip c.

[0041] The design focus of the utility model is that at least a first bend b1, a second bend b2 and a third bend b3 are arranged on the side plate a2 at intervals along the front-to-back direction, and the side plate a2 is bent outward at the first bend b1, and is bent inward at the second bend b2, and is bent inward at the third bend b3, so that: a U-shaped conductive clip c is bent on the side plate a2; with this bending structure, the overall width of the terminal material on the left and right is narrower, saving metal plate materials, and the contact area of ​​the conductive clip c can be made larger, which is beneficial to improving the reliability of conductive contact.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
