Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a spring-type multi-point contact terminal, a terminal module, and a power connector. Background Technology

[0002] Existing power connectors generally include male and female connectors. The male connector's pin-type terminals can be inserted into the square female connector's terminals to achieve contact and conductivity. The female terminals can use protruding contact bumps to contact the pin-type male terminals. Because these contact bumps cannot provide flexible deformation, the pins and contact bumps make rigid contact during insertion and removal, which can easily cause wear on the pins and affect their normal use. Furthermore, existing female terminals often use single contact bumps on both sides, which are prone to poor contact. During the transportation of electronic products, vibration can easily affect the connection stability between the male and female terminals. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please refer to Figure 1 Embodiment 1 of this utility model provides a spring-loaded multi-point contact terminal, including a terminal mating part 11, a terminal middle part 12, and a terminal wiring part 13. The terminal mating part 11, the terminal middle part 12, and the terminal wiring part 13 are connected sequentially from front to back, and the terminal mating part 11, the terminal middle part 12, and the terminal wiring part 13 are integrally stamped structures. The various components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the terminal mating part 11 has a square mating part body 111. The front end of the mating part body 111 has a first clearance hole 112 and two side contact springs 113 located in each first clearance hole 112. The two side contact springs 113 in the same first clearance hole 112 are arranged along the length direction of the mating part body 111. The two side contact springs 113 in the same first clearance hole 112 are symmetrical to each other and only one side is connected to the mating part body 111. The front end of the mating part body 111 has a top contact body 114 that is corresponding to the upper position of the first clearance hole 112 and is bent inward. The bottom of the front end inner wall of the mating part body 111 has a bottom contact spring 115 that is tilted backward and upward.

[0032] The side contact spring, top contact body, and bottom contact spring of this embodiment can form multi-point elastic contact, which can achieve good contact with the pin terminals of the mating connector, improve the stability of the connection, ensure more stable current or signal transmission, and prevent potential hazards such as power loss or signal interference caused by improper insertion or vibration during transportation. Moreover, it is less likely to cause wear on the pin terminals of the mating connector.

[0033] like Figure 1 As shown, the rear left and right sides of the main body 111 of the mating part are respectively provided with outwardly inclined locking springs 116, and the locking springs 116 are provided with first reinforcing ribs 1161. The locking springs 116 can engage with the connector housing of the power connector to prevent the terminals from disengaging from the connector housing.

[0034] like Figure 1 As shown, the terminal mating part is also provided with limiting baffles 117 on the left and right sides of the rear end of the mating part body 111, and a second reinforcing rib 121 is provided between the terminal middle part 12 and the terminal wiring part 13.

[0036] Please refer to Figure 3Embodiment 2 of this utility model provides a spring-type multi-point contact terminal, which also includes a terminal mating part 11, a terminal middle part 12, and a terminal wiring part 13. The similarities will not be repeated. The difference is that, based on the above embodiment 1, this embodiment 2 also provides a reinforcing sleeve 14 on the front end of the mating part body 111. The left and right sides of the reinforcing sleeve 14 are respectively provided with second clearance holes 141 and two abutting spring pieces 142 located in each second clearance hole 141. The two abutting spring pieces 142 in the same second clearance hole 141 are arranged along the length direction of the reinforcing sleeve 14. The two side contact spring pieces 113 in the same second clearance hole 141 are connected to the reinforcing sleeve 14 on only one side. Each abutting spring piece 142 abuts against the outer surface of its corresponding side contact spring piece 113.

[0037] In this embodiment 2, the abutting spring of the reinforcing sleeve can abut against the outside of the side contact spring 113, giving the side contact spring 113 a positive force. This allows the spring-type multi-point contact terminal to meet both the requirements of high conductivity and its positive force.

[0038] like Figure 4 and Figure 5 As shown, in order to prevent the reinforcing sleeve 14 from detaching from the terminal, anti-detachment locking holes 143 can be provided on the left and right sides of the rear end of the reinforcing sleeve 14. Correspondingly, anti-detachment buckles 118 can be provided on the left and right sides of the main body of the docking part. The anti-detachment buckles 118 can be inserted into the anti-detachment locking holes 143 to achieve the function of preventing detachment.

[0039] In addition, such as Figure 6 and Figure 7 As shown, the bottom of the reinforcing sleeve 14 can also be provided with an additional limiting buckle 145. Correspondingly, the bottom of the docking part body 111 can also be provided with a limiting hole 119 located at the position of the bottom contact spring 115. The limiting buckle 145 can be inserted into the limiting hole 119 to play a limiting role.

[0040] Even better, the inner wall of the reinforcing sleeve 14 may also be provided with a clamping protrusion 144 for clamping with the outer wall of the docking part body 111, the clamping protrusion 144 protruding inward from the inner wall of the reinforcing sleeve 14.

The middle portions 12 of two adjacent spring-type multi-point contact terminals 1 can be connected by an arched connecting portion 10.

[0043] To enhance the structural strength between the two spring-type multi-point contact terminals and prevent deformation of the arched connection 10, a recessed reinforcing rib 101 can be provided on the arc-shaped curved part of the arched connection 10. The recessed reinforcing rib 101 can be stamped by existing stamping equipment and is flat.

[0044] Example 4

[0045] Please refer to Figure 9 and Figure 10 As shown, Embodiment 4 of this utility model provides a power connector, which includes a connector housing 2. The connector housing 2 has a terminal insertion hole inside, and a terminal module identical to that in Embodiment 3 above can be installed in the terminal insertion hole.

[0046] Of course, depending on actual needs, multiple spring-type multi-point contact terminals of the above embodiment 1 or embodiment 2 can also be installed in the terminal insertion hole. In this case, the terminals do not need to form a module.
