[0026] The utility model provides a torsion spring module and an electrical connector.

[0027] See also Figure 1 and Figure 2 In one embodiment of the present invention, the torsion spring module 1 includes:

[0028] a first end portion 10;

[0029] A second end portion 30 is disposed opposite to the first end portion 10; and

[0030] The rib 20 has two ends respectively connected to the first end 10 and the second end 30. A plurality of the ribs 20 are provided, and the plurality of the ribs 20 are arranged at intervals along the circumferential direction. The rib 20 includes a special-shaped rib 22 and a straight rib portion 21 provided at both ends of the special-shaped rib 22, and the width of the special-shaped rib 22 is greater than the width of the straight rib portion 21.

[0031] In the technical solution of the present invention, the torsion spring module 1 includes a first end 10, a second end 30 and a rib 20 arranged between the first end 10 and the second end 30. A gap is formed between any two adjacent ribs 20. The torsion spring module 1 is a structure with both ends open. The rib 20 includes a special-shaped rib 22 in the middle section. Straight ribs 21 are respectively provided at both ends of the special-shaped rib 22. The end of the straight rib 21 away from the special-shaped rib 22 is connected to the first end 10 / the second end 30, wherein the width of the special-shaped rib 22 is greater than the width of the straight rib 21. When the pin 2 is inserted from the opening at one end and contacts the rib 20 in the middle part, that is, the pin 2 contacts the special-shaped rib 22 for computer transmission, due to the large width of the special-shaped rib 22, the contact area with the pin 2 is correspondingly expanded, the transmission resistance is reduced, and the loss of electric energy is correspondingly reduced, which facilitates electric energy transmission.

[0032] In the embodiments of the present invention, please refer to Figure 1 The two ends of the rib 20 are staggered in the axial direction of the torsion spring module 1, and the rib 20 is bent to form a waisted structure. The two ends of the torsion spring structure are open, and the middle is bent inward and contracted. When the pin 2 is inserted, the rib 20 with its middle part is completely in contact with the position of the pin 2 extending into the middle part of the torsion spring module 1, thereby realizing the transmission of electrical energy.

[0033] In an embodiment of the present invention, one side of the special-shaped rib 22 in the width direction protrudes in a direction away from the special-shaped rib 22 , and the other side edge of the special-shaped rib 22 in the width direction is wavy.

[0034] Please refer to Figure 1 and Figure 2 The special-shaped rib 22 includes a first side 221 and a second side 222. Since the rib 20 is twisted with the torsion spring module 1, the first side 221 is configured to protrude outward to expand the width of the special-shaped rib 22, and the second side 222 is configured to be wavy. The middle of the second side 222 is configured to better contact the pin 2 when the rib 2 is twisted, thereby increasing the effective path for current transmission and avoiding the special-shaped rib 22 protruding outward on both sides to expand the width, resulting in excessive strength in the middle of the special-shaped rib 22 and an overall tilt in the widened area. That is, after the pin 2 is inserted, it can only contact a straight surface of the widened area of ​​the special-shaped rib 22, but cannot achieve the effect of expanding the contact surface. After the rib 22 is deformed by pressure, it can better fit the surface of the pin, facilitating compensation for any minor unevenness or deflection, ensuring uniform contact pressure, and facilitating current transmission. It should be noted that the width of the smallest part of the special-shaped rib 22 is also greater than the width of the straight rib 21 to reduce power loss.

[0035] Please refer to Figure 2In an embodiment of the present invention, the length of the special-shaped rib 22 is 1 / 3 of the length of the rib 20. The special-shaped rib 22 is located in the middle of the entire rib 20, and its length is 1 / 3 of the total length of the rib 20. Under the condition of supporting strength of the torsion spring module 1, the contact area with the pin 2 is effectively expanded when the rib 20 is twisted, which facilitates the transmission of electrical energy and avoids the waste of cost by setting the straight rib portion 21 as a wide structure.

[0036] Please refer to Figure 2 In one embodiment, the width of the special-shaped rib 22 ranges from 0.62 mm to 0.96 mm. Generally, the width of the straight rib 21 is usually selected to be 0.62 mm, and the width of the special-shaped rib 22 is selected to be greater than 0.62 mm and less than or equal to 0.96 mm. When the torsion spring module 1 is twisted, it can ensure that it plays a supporting role and facilitates the insertion and removal of the pin 2. In addition, the special-shaped rib 22 is the middle part and is closer to the central axis. The width of the special-shaped rib 22 is increased, so that its contact area with the pin 2 is larger, and the effect of transmitting electrical energy is better.

[0037] In another embodiment, the thickness of the first end portion 10, the second end portion 30 and the rib 20 is 0.5 mm. The thickness affects the elastic coefficient and deformation of the overall structure, and then affects the contact pressure with the pin 2. If the rib 20 is thicker, it can usually provide a large contact pressure, but it affects the insertion and removal of the pin 2. If the rib 20 is too thick, the elasticity is poor, and if it is too thin, it is easy to break after the pin 2 is inserted and removed multiple times. The use of a torsion spring module 1 with a thickness of 0.5 mm can meet excellent insertion and removal performance and conductive effect.

[0038] In an embodiment of the present invention, the first end portion 10, the second end portion 30 and the rib 20 are made of metal. Preferably, the first end portion 10, the second end portion 30 and the rib 20 are made of beryllium copper C17510. Since beryllium copper C17510 has very high tensile strength and elasticity, it can provide long-term stable electrical connection, reduce connection failure caused by spring fatigue, and also enable the torsion spring module 1 to undergo elastic deformation when the pin 2 is inserted into the torsion spring module 1, and to be in close contact with the pin 2. After the pin 2 is plugged in and out multiple times, it still maintains good plugging and unplugging performance, and its high electrical conductivity ensures low contact resistance, improves power transmission efficiency, and reduces energy loss. In addition, beryllium copper C17510 has excellent wear resistance and corrosion resistance, and can frequently come into contact with machinery without being easily worn.

[0039] In an embodiment of the present invention, the first end portion 10, the second end portion 30 and the rib 20 are integrally stamped and formed, which can ensure a seamless connection between the rib 20 and the first end portion 10 and the second end portion 30, thereby improving the strength and reliability of the overall structure and improving production efficiency while ensuring the accuracy of the torsion spring module 1.

[0040] The present invention also provides an electrical connector, which includes a torsion spring module 1. The specific structure of the torsion spring module 1 refers to the above embodiment. Since the present torsion spring module 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. Figure 3 The electrical connector further includes a mounting base having a socket, the torsion spring module 1 is mounted in the socket, the pin 2 is inserted into the torsion spring module 1 from the first end 10, and contacts the rib 22 to transmit electrical energy.

[0041] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
