[0002] In the field of electrical connection, many electrical circuits need to be connected with terminals. Currently, clamping terminals are usually used to clamp flat terminals to achieve connection. The clamping terminals rely on their own elasticity to apply a holding force to the flat terminals. In many cases, the clamping force is small and it is easy to cause the two to separate. Or the clamping force is insufficient, causing the actual contact area between the terminal and the flat terminal to become smaller, the resistance to increase, the heat generation to exceed the standard, and the temperature to rise. Especially in high-voltage charging, the rapid increase in temperature can easily cause accidents that endanger life and property safety. Therefore, a new solution is urgently needed in the prior art to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A terminal 100, such as Figure 1-Figure 5 As shown, one end clamps and connects the sheet-like terminal 200, and the other end connects the wire 300. The terminal 100 includes a clamping portion 1, a connecting portion 2 and a crimping portion 3 connected in sequence. The clamping portion 1 includes a first clamping portion 11 and a second clamping portion 12 arranged opposite to each other, and a pressing mechanism 4 arranged on the clamping portion 1; the first clamping portion 11 and the second clamping portion 12 are provided with a plurality of opposite slots 5 along the direction in which the sheet-like terminal 200 is inserted, the pressing mechanism 4 includes a first pressing portion 41 and a second pressing portion 42 arranged opposite to each other, and a plurality of connecting ribs 43 connecting the same side of the first pressing portion 41 and the second pressing portion 42, the plurality of connecting ribs 43 pass through the plurality of slots 5, the first pressing portion 41 and the second pressing portion 42 are respectively located on the outside of the first clamping portion 11 and the second clamping portion 12 and press the first clamping portion 11 and the second clamping portion 12 inwardly under the elastic force of the connecting ribs 43, and the crimping portion 3 is connected to the wire 300.

[0026] The clamping part 1 of the terminal 100 is used to clamp the sheet terminal 200. If the clamping force is insufficient, it is easy to cause the contact area between the terminal 100 and the sheet terminal 200 to be too small, resulting in excessive resistance between the two and affecting conductivity. Therefore, a pressing mechanism 4 is set on the clamping part 1. The first pressing part 41 and the second pressing part 42 of the pressing mechanism 4 are connected by a plurality of connecting ribs 43. The first pressing part 41 and the second pressing part 42 press the first clamping part 11 and the second clamping part 12 inwardly respectively, so that the clamping part 1 can apply a greater holding force to the sheet terminal 200, thereby preventing the terminal 100 and the sheet terminal 200 from separating. The first clamping part 11 and the second clamping part are provided with a plurality of slots 5 opposite to each other along the direction of insertion of the sheet terminal 200, and the connecting ribs 43 are provided through the slots 5, so that the pressing mechanism 4 is provided on the clamping part 1, which is convenient for the installation of the two.

[0027] In some embodiments, the plurality of slots 5 penetrate the free ends of the first clamping portion 11 and the second clamping portion 12, dividing the free ends of the first clamping portion 11 and the second clamping portion 12 into a plurality of contact fingers 6. The plurality of contact fingers 6 squeeze the sheet terminal 200 from both sides, and obtain a greater pressure through a smaller contact area to ensure a stable connection.

[0028] In some embodiments, the distance between the first clamping portion 11 and the second clamping portion 12 gradually decreases from the end where the clamping portion 1 is connected to the connecting portion 2 to the free end, so that the free end can apply a greater clamping force to the blade terminal 200 .

[0029] In some embodiments, the free ends of the first clamping portion 11 and the second clamping portion 12 are provided with a guide portion 13 extending in a direction away from the axial direction of the terminal 100. Figure 4 As shown, the guide portion 13 can be used to guide the blade terminal 200 into the clamping portion 1, thereby allowing a slight error during insertion.

[0030] In some embodiments, the outer surfaces of the places where the free ends of the first clamping portion 11 and the second clamping portion 12 are connected to the guide portion 13 form an arc-shaped groove 14. Figure 4 As shown, the free ends of the first extrusion portion 41 and the second extrusion portion 42 are at least partially located in the groove 14. The groove 14 enables the first extrusion portion 41 and the second extrusion portion 42 to be stably extruded on the first clamping portion 11 and the second clamping portion 12, providing a more secure extrusion force.

[0031] In some embodiments, the connecting rib 43 is located at the bottom of the slot 5 and extends from the slot 5 to the outer surface of the first clamping part 11 and the second clamping part 12, and then connected to the first extrusion part 41 and the second extrusion part 42. The connecting rib 43 passes through the slot 5 and is fixed on the clamping part 1, and is not easy to fall off.

[0032] In some embodiments, the initial distance between the free ends of the first extrusion portion 41 and the second extrusion portion 42 is smaller than the minimum distance between the outer surfaces of the first clamping portion 11 and the second clamping portion 12. The initial distance refers to the distance between the free ends of the first extrusion portion 41 and the free ends of the second extrusion portion 42 when the extrusion mechanism 4 is in a natural state, so that when the extrusion mechanism 41 is installed on the clamping portion 1, it will apply an extrusion force inward to the outside of the clamping portion 1, so as to better clamp the sheet terminal 200.

[0033] In some embodiments, the connecting portion 2 includes a first connecting portion 21 and a second connecting portion 22 that are arranged opposite to each other, and a third connecting portion 23 that connects the sides of the first connecting portion 21 and the second connecting portion 22. The first connecting portion 21 and the second connecting portion 22 are respectively connected to the first clamping portion 11 and the second clamping portion 12. Thus, the terminal 100 becomes an integral structure, which is convenient for production and use.

[0034] In some embodiments, an inwardly recessed snap-in groove 24 is disposed on the other side of the first connection portion 21 and the second connection portion 22 relative to the third connection portion 23. The snap-in groove 24 can be used to fix the terminal 100 in a use position.

[0035] In some embodiments, the terminal 100 is formed by stamping and bending a metal plate. The processing method of stamping and curling a plate is simple and has a mature process. The terminal 100 can be manufactured quickly and in large quantities, saving processing costs and improving production efficiency.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
