[0026] See also Figure 1-4 The clamp double-contact connector includes a male connector 1 and a female connector 2. The male connector 1 includes a first substrate 11 and a rigid terminal 12 fixed to the first substrate 11. The female connector 2 includes a female socket body 21, a second substrate 22, and a clamp terminal 23 fixed to the second substrate 22. One end of the rigid terminal 12 and one end of the clamp terminal 23 are in contact and conductive contact within the female socket body 21.
[0027] Specifically, the first substrate 11 is a rectangular parallelepiped structure with a hole for the rigid terminal 12 to pass through. One end of the hole is configured with an inner diameter gradually decreasing along the hole direction to facilitate insertion of the rigid terminal 12. The minimum inner diameter of the hole is equal to the maximum outer diameter of the rigid terminal 12. The rigid terminal 12 is an elongated structure with both ends configured with an outer diameter gradually decreasing along the end direction to facilitate insertion into the hole or the clamp terminal 23. The rigid terminal 12 passes through the hole in the first substrate 11 and extends toward the female connector 2.
[0028] The clamp terminal 23 is a resilient terminal comprising a terminal foot 231, a terminal handle 232, a clamping double force arm 233, a first terminal head 234, and a second terminal head connected in sequence. The terminal foot 231 is fixed to the second substrate 22 for connection to an external wire. The terminal handle 232 extends perpendicularly to the second substrate 22. The clamping double force arm 233 is fixed to the terminal handle 232 at a certain angle. The two force arms are parallel to each other, and the distance between the force arms is greater than the maximum outer diameter of the rigid terminal 12. The first terminal head 234 and the second terminal head are respectively disposed at the ends of the two force arms for electrical contact with the rigid terminal 12. In this embodiment, the middle portions of the first terminal head 234 and the second terminal head protrude toward each other to form a contact point. The width of the first terminal head 234 and the second terminal head, away from the clamping double force arm 233, gradually decreases along the extension direction from the contact point, while the distance between the first terminal head 234 and the second terminal head gradually increases, facilitating insertion of the rigid terminal. In other embodiments, the middle section of the first terminal head 234 protrudes toward the second terminal head to form a contact point.
[0029] The female base body 21 is an insulator, and one end is provided with a slot for inserting the clamp terminal 23. The terminal foot 231 of the clamp terminal 23 is fixed to the second substrate 22. The terminal handle 232, the clamp double force arm 233, the first terminal head 234, and the second terminal head are inserted into the female base body 21. The other end of the female base body 21 is provided with a first plug hole 211 with an inner diameter that gradually increases toward the end to facilitate the insertion of the rigid terminal 12. The first plug hole 211 is connected to the slot. The inner diameter of the first plug hole 211 gradually decreases toward the inward direction of the entrance. The rigid terminal 12 automatically adjusts its direction when inserted. Even if it is inserted crookedly, it will not damage the female base body 21 and the rigid terminal 12, providing safety performance.
[0030] The slot of the female socket body 21 includes an upper slot portion and a lower slot portion. The upper slot portion is wider, and the lower slot portion is connected to the first jack 211. The terminal handle 232 of the clamp terminal 23 is wider than the overall width of the clamp double force arm 233, the first terminal head 234, and the second terminal head. When the clamp terminal 23 is inserted into the slot, the terminal handle 232 is locked in the upper slot portion, and the clamp double force arm 233, the first terminal head 234, and the second terminal head portion are inserted into the lower slot portion, making contact and conducting with the rigid terminal 12 inserted into the first jack 211 at the other end.
[0031] The second substrate 22 is a PCB board. Preferably, a second insertion hole 221 is formed on the second substrate 22 corresponding to the lower portion of the slot, and the rigid terminal 12 can be inserted into the female socket body 21 through the second insertion hole 221 on the second substrate 22 to contact and conduct with the clamp terminal 23.
[0032] During operation, the rigid terminal 12 is inserted into the female socket body 21 from the first socket 21 or inserted into the female socket body 21 from the second socket 221 on the second substrate 22. When the rigid terminal 12 is inserted into the contact position of the clamp terminal 23, the first terminal head 234 and the second terminal head clamp the rigid terminal 12, and the contact is in contact and conductive with the rigid terminal 12. The terminal handle 232 and the first terminal head 234 and the second terminal head are located on different planes and will not interfere with the insertion of the rigid terminal 12.
[0033] The clamp double-contact connector design of the present invention adopts a clamp-shaped terminal with two contacts. When in contact with the rigid terminal 12, the two symmetrical contact points clamp the rigid terminal, and the contact area is large, which reduces the connection resistance and increases the stability of the electrical connection. The clamp double force arm 233 clamps the rigid terminal, and the mechanical reliability is better.
[0034] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
