Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, and more specifically, to a series-connected folding terminal tape structure. Background Art

[0002] Generally, various terminals are provided inside an electronic connector. The common processing solutions for stamping terminal tapes on the market are usually as Figure 1 and Figure 2 shown. The material required for the original terminal forming is not fully unfolded, resulting in the PIN pitch of the terminal being longer than the PIN pitch required by the connector. To obtain the finished product state, the connection part of the tape needs to be cut off, and then the terminals are rearranged and connected in series by other off-line processing methods (such as tape connection, fixture clamping, etc.), and the PIN pitch is shortened to match the length of the connector (that is, 5 mm of H1 becomes 3 mm of H2). The original method requires twice the process or working hours to assemble, the process is complex, the operation process is more cumbersome, time-consuming and laborious, the cost is relatively high, and the cut terminal tape will affect the structural strength of the tape itself and the accuracy during assembly. Content of the Utility Model

Each first connection part is connected to the corresponding second connection part, each second connection part is connected between the corresponding first connection part and the corresponding terminal, each bending connection part is connected between two adjacent second connection parts, and each bending connection part bends and protrudes in the same direction.

[0005] Preferably, each bending connection part is set as an arc shape, a V shape or an M shape.

[0006] Preferably, the middle part of the protruding top end of the bending connection part is recessed inward by flattening to form a groove, and a reinforcing rib is formed in the middle of the recessed side of the groove.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 3 , an embodiment of the present utility model provides a series-connected folding type terminal strip structure, including a strip body 1 and a plurality of terminals 2 extending from the end of the strip body 1. Each component of this embodiment will be described in detail below with reference to the accompanying drawings.

[0023] As Figures 3 to 4 shown, the strip body 1 may include a plurality of first connection parts 3, a plurality of second connection parts 4, and a plurality of bending connection parts 41 formed by stamping and bending. Each first connection part 3 is connected to the corresponding second connection part 4. Each second connection part 4 is connected between the corresponding first connection part 3 and the corresponding terminal 2. Each bending connection part 41 is connected between two adjacent second connection parts 4, and each bending connection part 41 bends and protrudes in the same direction.

[0024] In this embodiment, each bending connection part 41 may be set as an arc shape, a V shape, an M shape, or other foldable shapes.

[0025] Specifically, a positioning hole 42 may be provided in the middle of the second connection part 4, which is used for positioning the strip.

[0026] Preferably, the middle part of the protruding top end of the bending connection part 41 can be recessed inward by flattening to form a groove 411, and a reinforcing rib 412 can be formed in the middle of the recessed side of the groove 411. Among them, the shape of the groove 411 can be preferably set as a rectangle.

[0027] As Figure 5 shown, each terminal 2 can include a terminal insertion part 21 and a wire connection part 22. The wire connection part 22 is located at one end of the terminal insertion part 21. The terminal insertion part 21 has a cylindrical structure, and the wire connection part 22 is a riveting structure. Among them, the riveting structure of the wire connection part 22 can be used for pressing the wire core.

[0028] Preferably, the terminal insertion part 21 can include a hollow square tube 211 formed by bending the two sides of the terminal 2 inward. Through holes 212 are opened on both sides of the upper end of the hollow square tube 211. Further, elastic lugs 213 are provided at one end of each through hole 212, and the elastic lugs 213 are inclined outward.

[0029] Among them, the elastic lugs 213 can maintain good insertion buffering, which is convenient for clamping and connecting after insertion. The elastic lugs 213 play an elastic buffering role and can extend the service life of the terminal.

[0030] As Figure 6 shown, the utility model can achieve the same length (H3 is 3 mm) matching the connector through one-time series forming by stamping and bending. When assembling with the connector, the middle part of the protruding top end of the bending connection part is recessed inward by flattening to form a groove, and a reinforcing rib is formed in the middle of the recessed side of the groove. The reinforcing rib can increase the structural strength of the bending connection part, make the strip structure not easy to deform and keep straight, which is beneficial to the assembly of the terminal strip and the seat body of the connector.

[0031] To sum up, the structure of the utility model is simple and reasonable. By providing a bending connection part formed by stamping and bending at the second connection part of the strip body, it can connect the terminals on the strip in series at one time. And when the strip is formed and assembled with the seat body of the connector, the distance between the terminals does not need to change, and it is not necessary to cut off the connection between the terminal strips in advance. It is convenient for the terminals on the terminal strip to be directly and quickly assembled with the seat body of the connector, changing the way that the terminal strips in the prior art must be connected in series by an off-line method after being cut off. The utility model adopts a folded connection strip structure, which can make the process simpler and faster, save working hours, reduce production costs, and ensure the structural strength of the strip itself and the accuracy during assembly. In addition, it can also make the subsequent terminal wire welding process faster and simpler.
