Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a convex-shaped elastic 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.

[0037] Example 1

[0038] Please refer to Figure 1 Embodiment 1 of this utility model provides a convex-shaped elastic 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.

[0039] like Figures 1 to 3As shown, the terminal mating part 11 has a square mating part body 111. The front left and right sides of the mating part body 111 are respectively provided with first clearance holes 112 and elastic contact bodies 113 located in each first clearance hole 112. Preferably, each first clearance hole 112 is provided with three elastic contact bodies 113 spaced apart. Each elastic contact body 113 is arranged along the height direction of the mating part body 111. Only the lower end (or upper end) of each elastic contact body 113 is connected to the mating part body 111. The inner surface of each elastic contact body 113 is provided with a first contact protrusion 114.

[0040] The elastic contact 113 can undergo elastic deformation, so that the terminal mating part 11 can achieve good contact with the pin terminals of the mating connector, and is not prone to wear on the pin terminals of the mating connector.

[0041] like Figure 2 and Figure 3 As shown, as a further improvement of this embodiment, the top front end of the docking body 111 may also be provided with an inwardly convex contact body 115 that corresponds to the upper position of the first clearance hole 112 and is bent inward (such as arc). The inwardly convex contact body 115 may be elastic. In addition, the bottom of the inner wall of the front end of the docking body 111 may also be provided with a second contact protrusion 116. Preferably, three second contact protrusions 116 may be provided and spaced apart along the length direction of the docking body 111.

[0042] In addition to the elastic contact body and the first contact convex hull, this embodiment can also add an inner convex contact body and a second contact convex hull to form multi-point elastic contact. This can further 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.

[0043] like Figure 1 As shown, the rear left and right sides of the main body 111 of the mating part can be provided with outwardly inclined locking springs 117, and the locking springs 117 can be provided with first reinforcing ribs 118.

[0044] like Figure 1 As shown, the terminal mating part 11 may also be provided with limiting baffles 119 on the left and right sides of the rear end of the mating part body 111. The limiting baffles 119 can limit the inner wall of the connector housing of the power connector.

[0045] In addition, such as Figure 1 As shown, a second reinforcing rib 121 may also be provided between the middle part 12 of the terminal and the terminal wiring part 13.

[0046] It should be noted that the number of elastic contact bodies, first contact bulges, and second contact bulges can be increased or decreased arbitrarily according to actual needs, and are not limited to this embodiment.

[0047] In other embodiments, the inner convex contact 115 can also be disposed at the bottom front end of the mating body 111, and the second contact protrusion 116 can also be disposed at the top of the inner wall of the front end of the mating body 111. Of course, depending on actual needs, the second contact protrusion 116 on the terminal can also be replaced by the inner convex contact 115, and similarly, the inner convex contact 115 on the terminal can also be replaced by the second contact protrusion 116.

The left and right sides of the reinforcing sleeve 14 are respectively provided with second clearance holes 141 and two independent first abutting springs 142 located in each second clearance hole 141. The first abutting springs 142 are arranged along the length direction of the reinforcing sleeve 14. Each first abutting spring 142 is connected to the reinforcing sleeve 14 on only one side. The first abutting spring 142 can abut against the outside of the elastic contact body 113.

[0050] like Figure 7 and Figure 8 As shown, in order to prevent the reinforcing sleeve 14 from detaching from the terminal, the bottom of the reinforcing sleeve 14 may be provided with a first anti-detachment buckle 143. Correspondingly, the bottom of the docking part body 111 may be provided with a first anti-detachment hole 1110. The first anti-detachment buckle 143 can be inserted into the first anti-detachment hole 1110 to achieve the function of preventing detachment.

[0051] In this embodiment 2, the first abutting spring of the reinforcing sleeve can abut against the outside of the elastic contact body, giving the elastic contact body a positive force. This enables the convex-shaped elastic contact terminal to meet both the high conductivity requirement and the positive force requirement.

The second abutting springs 144 are arranged along the height direction of the reinforcing sleeve 14. Only the lower end (or upper end) of the second abutting springs 144 is connected to the reinforcing sleeve 14. The inner surface of the second abutting springs 144 is provided with abutting protrusions 1441 for contacting the outer surface of the elastic contact body 113. The second abutting springs 144 abut against the outer surface of each elastic contact body 113.

[0055] To prevent the reinforcing sleeve 14 from detaching from the terminal, the left and right sides of the rear end of the reinforcing sleeve 14 are respectively provided with second anti-detachment locking holes 145, and the left and right sides of the main body of the docking part are respectively provided with second anti-detachment buckles 1111. The second anti-detachment buckles 1111 can be inserted into the second anti-detachment locking holes 145 to achieve the function of preventing detachment.

[0056] In addition, the inner wall of the reinforcing sleeve 14 may be provided with a clamping protrusion 146 for clamping with the outer wall of the docking part body 111, and the clamping protrusion 146 protrudes inward from the inner wall of the reinforcing sleeve 14.

[0057] In this embodiment 3, the second abutting spring of the reinforcing sleeve can abut against the outside of the elastic contact body, giving the elastic contact body a positive force. This enables the convex-shaped elastic contact terminal to meet both the high conductivity requirement and the positive force requirement.

[0058] Example 4

[0059] Please refer to Figure 11 Embodiment 4 of this utility model provides a terminal module, which includes a plurality of convex-shaped elastic contact terminals 1 that are the same as those in Embodiment 2 or Embodiment 3 above. The terminal middle portions 12 of two adjacent convex-shaped elastic contact terminals 1 can be connected by an arched connecting portion 10.

[0060] To enhance the structural strength between the two convex-shaped elastic 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.

[0061] Example 5

[0062] Please refer to Figure 12 and Figure 13 As shown, Embodiment 5 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 4 above can be installed in the terminal insertion hole.

[0063] Of course, depending on actual needs, multiple convex-shaped elastic contact terminals of the above embodiments 1, 2 or 3 can also be installed in the terminal insertion hole. In this case, the terminals do not need to form a module.

[0064] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
