Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an elastic terminal and a double-contact connector thereof. Background Art

[0002] A connector is a highly stable circuit connection component, typically consisting of male and female terminals that connect to each other for electrical connection. The female terminals of traditional connectors typically feature a single-arm, single-contact point, which creates electrical connection when in contact with the rigid male terminals.

[0003] However, existing connectors have disadvantages such as low positive pressure at the contact point of the single-arm, high connection resistance, unstable contact performance, easy fatigue failure due to elastic deformation of the single-arm, and contact failure leading to circuit disconnection. Utility Model Content

[0006] The elastic terminal of the utility model has a larger overall contact area between the two contacts, a smaller connection resistance, and better electrical connection performance. The design of the two force arms and the large range of elastic deformation stroke of the force arms make the mechanical reliability of the connector better and the electrical connection more stable when in use. The one-piece molding design makes it easier to perform electroplating manufacturing.

[0007] Furthermore, the first force arm is fixedly connected to the terminal handle at a certain angle, and the protrusion on the first force arm protrudes toward a side away from the terminal handle.

[0008] Furthermore, the second contact point and the first contact point are located in the same plane.

[0009] Furthermore, the first lever arm is arc-shaped.

[0011] Furthermore, the rigid terminal is a long strip structure, and both ends thereof are configured to have an outer diameter gradually decreasing along the end direction.

[0012] Furthermore, one end of the female socket body is provided with a slot for inserting the elastic terminal, and the other end is provided with a jack for inserting the rigid terminal, and the jack is communicated with the slot.

[0013] Furthermore, the slot of the female socket body includes an upper slot and a lower slot, the width of the upper slot is wider than the width of the lower slot, and the lower slot is connected to the jack; the terminal handle of the elastic terminal is wider than the overall width of the first force arm and the second force arm; the terminal handle is clamped in the upper slot, and the first force arm and the second force arm are inserted into the lower slot.

[0021] Example 1

[0022] See also Figure 1-4 The connector includes a male connector 1 and a female male 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 and an elastic terminal 22 fixed in the female socket body 21. The rigid terminal 12 and the elastic terminal 22 are in contact and conductive with each other in the female socket body 21.

[0023] 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 to have an inner diameter gradually decreasing along the hole direction to facilitate the 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 to have an outer diameter gradually decreasing along the end direction to facilitate insertion into the hole or the female socket body 21. The rigid terminal 12 passes through the hole on the first substrate 11 and extends toward the female connector 2.

[0024] The elastic terminal 22 is provided with two protrusions for electrically contacting the rigid terminal 12, namely the first contact and the second contact. Specifically, the elastic terminal 22 includes a terminal shank 221, a first force arm 222, and a second force arm 223, which are connected in sequence. The overall width of the terminal shank 221 is greater than the overall width of the first force arm 222 and the second force arm 223. The first force arm 222 is fixedly connected to the terminal shank 221 at a certain angle, and a protrusion is provided in the middle of the first force arm 222 in a direction away from the terminal shank 221, forming a first contact. One end of the second force arm 223 is fixedly connected to the end of the first force arm 222, and a protrusion is provided in the middle, forming a second contact in the same direction as the protrusion of the first contact. When the elastic terminal 22 is mated with the rigid terminal 12, the first contact and the second contact are in contact and conduction with the rigid terminal 12.

[0025] The female base body 21 is an insulator, and one end is provided with a slot for inserting the elastic terminal 22. The terminal handle 221 is clamped in the slot, and the first force arm 222 and the second force arm 223 are located in the slot of the female base body 21; the other end of the female base body 21 is provided with a socket with an outer diameter gradually increasing towards the end to facilitate the insertion of the rigid terminal 12, and the socket is connected to the slot. Specifically, the slot of the female base body 21 includes an upper slot and a lower slot. The width of the upper slot is wider, and the lower slot is connected to the socket. When the elastic terminal 22 is inserted into the slot, the overall wider terminal handle 231 is clamped in the upper slot, and the first force arm 222 and the second force arm 223 are inserted into the lower slot, and are in contact and conduction with the rigid terminal 12 inserted into the socket at the other end.

[0026] The second contact and the first contact are located on the same plane, and the terminal handle 232 and the first contact and the second contact are located on different planes. During operation, the rigid terminal 12 is inserted into the jack of the female socket body 21, and the rigid terminal 12 first contacts the second contact and then contacts the first contact. The rigid terminal 12 continues to be inserted without interfering with the terminal handle 232.

[0027] In another embodiment, the second contact point and the first contact point are located on different planes. During operation, when the rigid terminal 12 is inserted into the socket of the female socket body 21, the rigid terminal 12 only contacts the second contact point. The design of two lever arms increases the elastic deformation range, improving connection stability and mechanical reliability.

[0028] Example 2

[0029] See also Figure 5 This embodiment is basically the same as embodiment 1, with the difference that: the elastic terminal 22 is provided with a protrusion for electrically contacting the rigid terminal 12, specifically a protrusion arranged in the middle of the second force arm 222 away from the terminal handle 221 to form a second contact point; the first force arm 222 is arc-shaped.

[0030] The second contact point and the first lever arm are located on different planes. During operation, when the rigid terminal 12 is inserted into the socket of the female socket body 21, the rigid terminal 12 only contacts the second contact point. The arc-shaped first lever arm 222 has a large elastic deformation range, which improves the mechanical reliability of the connector during use and makes the connection more stable.

[0031] The elastic terminal and the dual-contact connector of the present invention are connected to the rigid terminal 12 by the first contact and the second contact, so the contact area is large, the connection resistance is small, and the electrical connection performance is better. The design of two contacts and two force arms and the large elastic deformation range of the force arms make the mechanical reliability of the connector better when in use, and the one-piece molding design makes it easier to perform electroplating manufacturing.

[0032] 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.
