Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrical connectors, and particularly to a snap-fit, replaceable electrical connector. Background Technology
[0002] Electrical connectors are primarily used to establish electrical connections between electronic devices or modules for signal transmission. These electrical connections are achieved by mating male and female electrical connectors. Most existing male and female electrical connectors use a plug-in method for mating. After mating, the male and female connectors generate insertion and extraction forces through the engaging of the housing or core structure or friction between them.
[0003] Please see Figure 1 As shown, it represents a wire-to-board electrical connector assembly used to form an electrical connection between a power supply and a motherboard in a computer device. The male electrical connector A is connected to the power supply (not shown) via cable C, and the female electrical connector B is soldered to the motherboard E. By mating the male electrical connector A and the female electrical connector B, an electrical connection is formed between the power supply and the motherboard E, thereby enabling the power supply to supply power to the motherboard.
[0004] To prevent detachment after mating, the existing male connector A has a locking element D on its side wall. Please refer to [further details]. Figure 2 As shown, the latching component D includes a latching component body D1 and a connecting portion D2. The latching component body D1 is connected to the side wall of the male electrical connector A via the connecting portion D2, and the male electrical connector A and the latching component D are integrally formed by plastic injection molding. The latching component body D1 includes a latching hook portion D11 and an operating portion D12. The connecting portion D2 is located between the latching hook portion D11 and the operating portion D12. When the user presses the operating portion D12, the connecting portion D2 undergoes elastic deformation, causing the latching hook portion D11 to move closer to or further away from the male electrical connector A. Thus, when the male electrical connector A is mated with the female electrical connector B, the latching hook portion D11 abuts against the stop rib B1 of the female electrical connector B, thereby positioning the male electrical connector A in the position of the female electrical connector B.
[0005] Please see Figure 3 As shown, under conditions of improper force application or frequent use, the locking element D is prone to breakage at the connection point D2. Since the male electrical connector A and the locking element D are an integrated structure, the male electrical connector A loses its locking function after the connection point D2 breaks and must be replaced as a whole, causing inconvenience to the user. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a snap-fit structure replaceable electrical connector to solve the problem that the electrical connector must be replaced as a whole after the snap-fit component of the prior art breaks.
[0007] This utility model provides a snap-fit replaceable electrical connector, including a connector body and a snap-fit member. The connector body includes a housing and a plurality of terminals disposed on the housing. The housing has a mounting surface and a snap-fit base disposed on the mounting surface. The snap-fit member includes a snap-fit member body and a snap-fit portion extending from the snap-fit member body in a direction away from the snap-fit member. The snap-fit portion snaps into the snap-fit base in a detachable manner.
[0008] In another embodiment, the engaging portion and the fastener body are an integrated structure.

Detailed Implementation
[0029] Please see Figure 4 The diagram illustrates an embodiment of the snap-fit replaceable electrical connector of this invention, showing its mating structure with a female electrical connector. The snap-fit replaceable electrical connector 1 of this embodiment is a male electrical connector, which forms an electrical connection via a female electrical connector 2 inserted onto a circuit board 3. While the snap-fit replaceable electrical connector 1 of this embodiment can be used with a power supply, this invention is not limited to this; it is also applicable to other types or applications of electrical connectors.
[0030] Please refer to the following: Figure 5 and Figure 6 As shown, this utility model embodiment provides a snap-fit replaceable electrical connector 1, including a connector body 10 and a snap-fit member 20. The snap-fit member 20 is snapped into the connector body 10 in a detachable structure, and the detachable structure is described in detail below.
[0031] The connector body 10 includes a housing 11 and a plurality of terminals (not shown) disposed on the housing 11. The housing 11 is cuboid, having a mounting surface 111 along its long side and an engaging base 112 disposed on the mounting surface 111. In this embodiment, the engaging base 112 is a hollow cuboid structure, including a mating groove 1121 and an engaging groove 1122. The mating groove 1121 is formed at the top 112a of the engaging base 112, and the opening of the mating groove 1121 is parallel to the mounting surface 111. The engaging groove 1122 is formed on a side wall 112b of the engaging base 112 adjacent to the top 112a, and the engaging groove 1122 communicates with the mating groove 1121. The engaging portion engages with the mating groove.
[0032] The fastener 20 includes a fastener body 21 and an engaging portion 22 extending from the fastener body 21 in a direction away from the fastener 20. In this embodiment, the engaging portion 22 includes two parallel extension plates 221 and a connecting neck 222. The two extension plates 221 are connected to the connecting neck 222, and the two extension plates 221 are connected to the fastener body 21 via the connecting neck 222. The thickness of the connecting neck 222 is less than the sum of the thickness of the two extension plates 221 and the distance d. A stepped structure is formed between the connecting neck 222 and the two extension plates 221. There is a gap d between the two extension plates 221. One of the extension plates 221 has a hook portion 221a. The hook portion 221a is disposed on a hook surface 221b of the extension plate 221. The hook surface 221b is located on the side away from the other extension plate 221. The hook portion 221a extends in a direction away from the other extension plate 221. The hook portion 221a includes a slope 221c and a vertical surface 221d adjacent to the slope 221c.
[0033] In this embodiment, the engaging hook portion 221a is provided only on one of the two extension plates 221, meaning that the surface of the other extension plate 221 is flat. However, this utility model is not limited to this. In other embodiments, both extension plates may be provided with engaging hook portions, and the engaging base may have an engaging groove on each of the two opposite side walls.
[0034] Please refer to the following: Figure 7 and Figure 8 As shown, when the latching member 20 engages with the engaging base 112 of the connector body 10, the engaging part 22 is inserted into the engaging groove 1121. At this time, the inclined surface 221c of the engaging hook 221a undergoes elastic deformation due to interference with the groove wall of the engaging groove 1121. Then, the engaging hook 221a moves along the groove wall of the engaging groove 1121 to the engaging groove 1122, and the engaging hook 221a enters the engaging groove 1122. At the same time, the vertical surface 221d of the engaging hook 221a abuts against the groove wall of the engaging groove 1122 to form a limit, thereby preventing the engaging part 22 from falling out of the engaging groove 1121. In order for the elastically deformed engaging hook 221a and another extension plate 221 to enter the engaging groove 1121, the distance d between the two extension plates 221 is greater than or equal to the sum of the height of the engaging hook 221a and the thickness of the extension plate 221.
[0035] Please refer to the following: Figure 9 and Figure 10As shown, when the user applies improper force or uses the device frequently, the connecting neck 222 of the engaging part 22 breaks. Because the hook 22a remains engaged in the engaging groove 1122 after the breakage, the engaging part 22 cannot be directly removed. In this case, a tool T, such as a flathead screwdriver, can be inserted into the engaging groove 1122. The tool T pushes the hook 221a, causing the extension plate 221 to elastically deform. Then, the tool T rotates while abutting the hook 221a, pushing the broken engaging part 22 out along the groove wall of the engaging groove 1121. After the broken engaging part 22 is removed from the engaging base 112, a new fastener 20 can be assembled onto the engaging base 112.
[0036] The snap-fit structure of this utility model provides a replaceable electrical connector. The snap-fit part of the snap-fit component engages with the snap-fit base of the connector body. When the snap-fit part of the snap-fit component breaks due to improper force or frequent use, the snap-fit part can be removed from the snap-fit base, and a new snap-fit component can be installed. This eliminates the need to replace the entire electrical connector as in previous technologies, increasing the convenience of use.
