Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a power connector. Background Art

[0002] Existing power connectors primarily feature a guide plate structure and a spring structure within an insulating housing. The spring structure is mounted on the guide plate and is used to clamp the tongue of the mating connector to form an electrical connection and transmit power. However, because the spring structure possesses sufficient elasticity to resiliently clamp the tongue of the mating connector, it can easily cause the tongue of the mating connector to wobble when subjected to force. This can cause one side of the spring structure to be squeezed, resulting in poor contact on the other side, thus affecting current conduction. Furthermore, over time, the existing spring structure, subjected to repeated deformation loads, can cause elastic fatigue, resulting in a decrease in the positive pressure at the contact point between the spring structure and the guide plate structure, further affecting current conduction.

[0003] In addition, the existing guide plate structure is mostly bent multiple times to form an inverted U-shape for the installation of the spring structure. However, since the inverted U-shaped structure is only connected on one side, the other side will form an open end, resulting in an unstable structure. It is easy to cause the guide plate structure to twist and deform due to the force, thereby affecting the assembly and positioning of the spring structure.

[0004] In view of this, the applicant has focused on the shortcomings of the above-mentioned prior art and has conducted in-depth research and applied scientific theories to try his best to solve the above-mentioned problems, which has become the goal of the applicant's improvement.

[0058] The detailed description and technical contents of this application will be described below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit this application.

[0059] The present application provides a power connector that can be inserted into and overlapped with the tongue plate A of a mating connector (not shown) to form an electrical connection for transmitting power. Figures 1 to 5 FIG. 1 shows a first embodiment of the power connector of the present application, which includes an insulating base 10 , a conductive base 20 and a leaf spring assembly 30 .

[0060] In this embodiment, the insulating base 10 is integrally molded by plastic injection molding, but the present application is not limited to this. For example, the insulating base 10 can also be made of other insulating materials, or made using other plastic processes. The insulating base 10 has a accommodating space 11, a plug hole 12, and a wiring hole 13. The accommodating space 11 is located inside the insulating base 10. The plug hole 12 and the wiring hole 13 extend from the surface of the insulating base 10 to the inside to the accommodating space 11, that is, the accommodating space 11 can be connected to the external space through the plug hole 12 or the wiring hole 13. In this embodiment, the wiring hole 13 extends vertically downward from the top of the insulating base 10 to the accommodating space 11, and the plug hole 12 extends horizontally inward from the side of the insulating base 10 to the accommodating space 11, but the present application is not limited to this. The setting position and setting direction of the wiring hole 13 and the plug hole 12 should be adjustable according to different needs. It is worth mentioning that the wiring hole 13 is used to insert a power cable (not shown) to conduct with the conductive seat 20, and the plug hole 12 is used to insert the tongue A of the docking connector.

[0061] In this embodiment, the conductive base 20 is a one-piece metal member with excellent electrical conductivity, but this application is not limited to this. The conductive base 20 can also be made of other materials with excellent electrical conductivity. The conductive base 20 is disposed within the accommodating space 11. Specifically, the insulating base 10 can be embedded in the accommodating space 11 to accommodate the conductive base 20, or the conductive base 20 can be inserted and fixed in the accommodating space 11. This application does not impose any further restrictions on this. The conductive base 20 mainly includes a wiring guide 21 and a pair of parallel fixing plates 22. The wiring guide 21 is connected to each fixing plate 22 and extends away from the insertion hole 12, so that the wiring hole 13 is aligned with the wiring guide 21. More specifically, the wiring guide 21 is perpendicular to the orientation of the wiring hole 13. Therefore, when the power cable is inserted through the wiring hole 13, it can abut the wiring guide 21 in the accommodating space 11 to form an electrical connection, thereby transmitting power to the conductive base 20. In this embodiment, each fixing plate 22 is substantially perpendicular to the wiring guide plate 21, but this is not a limitation. An installation space 221 is formed between each fixing plate 22. Each fixing plate 22 has an abutment block 222. Each abutment block 222 protrudes from the corresponding fixing plate 22 toward the installation space 221.

[0062] In this embodiment, the leaf spring assembly 30 is an integral metal part with good electrical conductivity, but the present application is not limited thereto. The leaf spring assembly 30 can also be made of other materials with good electrical conductivity. The leaf spring assembly 30 includes a connecting portion 31, a pair of elastic clamping portions 32, and a pair of claw portions 33. Each elastic clamping portion 32 is located in the installation space 221, and each elastic clamping portion 32 is respectively configured to correspond to each fixed plate 22. An insertion space 321 for inserting the tongue plate A is formed between each elastic clamping portion 32. The connecting portion 31 is connected to the side of each elastic clamping portion 32 away from the insertion hole 12. Each claw portion 33 is connected to the other side of each elastic clamping portion 32 (i.e., the side adjacent to the insertion hole 12), and each claw portion 33 is respectively buckled to the end of each fixed plate 22. Each elastic clamping portion 32 has a plurality of clamping leaf springs 322. The end of each clamping leaf spring 322 of each elastic clamping portion 32 abuts against the abutment block 222 of the corresponding fixing plate 22, thereby limiting the extension and deformation space of each clamping leaf spring 322, and allowing each clamping leaf spring 322 to firmly abut against each abutment block 222 without shaking or excessive deformation.

[0063] By this, Figure 4 and Figure 5 As shown, the tongue plate A can be inserted into the insertion space 321 through the insertion hole 12, so that the clamping leaf springs 322 of each elastic clamping portion 32 can elastically clamp the opposite sides of the tongue plate A together. In addition, since each fixing plate 22 has an abutment block 222 protruding toward the installation space 221, and each elastic clamping portion 32 has a plurality of clamping leaf springs 322 whose ends abut against the corresponding abutment blocks 222, the clamping stability of each clamping leaf spring 322 on the tongue plate A can be effectively increased, thereby increasing the positive pressure of each contact point when each clamping leaf spring 322 clamps the tongue plate A, and preventing each clamping leaf spring 322 from generating structural elastic fatigue and deformation failure. At the same time, the shaking range of the tongue plate A is limited so that each clamping leaf spring 322 is evenly stressed, thereby improving the current conduction effect of each clamping leaf spring 322.

[0064] Refer back Figures 2 to 4As shown, each elastic clamping portion 32 includes a plurality of support ribs 323 and connecting ribs 324. In each elastic clamping portion 32, each support rib 323 is connected between the connecting portion 31 and the connecting rib 324. In this embodiment, there are four support ribs 323 in each elastic clamping portion 32, and each support rib 323 is substantially perpendicularly connected between the connecting portion 31 and the connecting rib 324. However, this application is not limited to this. For example, the number of support ribs 323 may be only two, or each support rib 323 may be obliquely connected between the connecting portion 31 and the connecting rib 324. Each clamping leaf spring 322 corresponding to each elastic clamping portion 32 extends from the connecting rib 324 in the opposite direction toward its corresponding latching portion 33 and is located between each support rib 323. In other words, each clamping leaf spring 322 of each elastic clamping portion 32 in this embodiment is located within three spacings (not numbered) between the four support ribs 323. Therefore, the end of each clamping leaf spring 322 away from the latching portion 33 is suspended and can abut against the corresponding abutting block 222. The latching portion 33 corresponding to each elastic clamping portion 32 is connected to the connecting rib 324.

[0065] Furthermore, each clamping leaf spring 322 includes an extension section 3221, a first inclined section 3222, a second inclined section 3223, and an abutting section 3224. In each clamping leaf spring 322, the extension section 3221 extends from the connecting rib 324 in the opposite direction toward the corresponding latch portion 33, and a gap (not numbered in the figure) is formed between the extension section 3221 and the corresponding fixed plate 22 to serve as a collapse space for the clamping leaf spring 322 to deform when the tongue plate A is inserted. The first inclined section 3222 extends obliquely from the end of the extension section 3221 away from the latch portion 33 toward the insertion space 321. The second inclined section 3223 extends obliquely from the end of the first inclined section 3222 away from the latch portion 33 toward the corresponding fixed plate 22. The abutting section 3224 extends obliquely from the end of the second inclined section 3223 away from the latch portion 33 toward the insertion space 321, and the end of the abutting section 3224 away from the latch portion 33 abuts against the corresponding abutting block 222. Thus, each clamping leaf spring 322 is roughly lightning-shaped and has at least two turning points. Specifically, a first turning point is formed between the first inclined section 3222 and the second inclined section 3223 of each clamping leaf spring 322, and a second turning point is formed between the second inclined section 3223 and the abutting section 3224 of each clamping leaf spring 322. Each first turning point is configured to abut opposite sides of the tongue plate A, thereby clamping the tongue plate A and establishing an electrical connection. Each second turning point is configured to abut against each fixing plate 22, providing support for each clamping leaf spring 322 to clamp the tongue plate A.

[0066] To further illustrate, each latch portion 33 includes an attachment plate 331 and a barb 332. In each latch portion 33, the attachment plate 331 bends and extends from the connecting rib 324 of the corresponding elastic clamping portion 32 and is attached to the end surface of the corresponding fixing plate 22 facing the receptacle 12. The barb 332 in each latch portion 33 bends and extends from the attachment plate 331 and is engaged with the side of the corresponding fixing plate 22 away from the corresponding elastic clamping portion 32. Thus, by engaging the ends of the fixing plates 22 with the respective latch portions 33 of the leaf spring assembly 30, the leaf spring assembly 30 can be secured to the conductive base 20. In addition, since the ends of the abutting sections 3224 of each clamping leaf spring 322 abut against the abutting blocks 222 of each fixed plate 22, the second turning points of each clamping leaf spring 322 abut against each fixed plate 22, and the claw portions 33 of the leaf spring assembly 30 respectively snap into the ends of each fixed plate 22, the leaf spring assembly 30 can be firmly set on the conductive seat 20, so that each clamping leaf spring 322 can stably clamp the tongue plate A and effectively limit the tongue plate A to avoid shaking of the tongue plate A.

[0067] Refer back Figure 2 and Figure 3 As shown, the conductive base 20 also includes a connecting plate 23, a first connecting plate 24 and a second connecting plate 25. The connecting plate 23 is connected to one side of each fixed plate 22, and the first connecting plate 24 and the second connecting plate 25 extend from the other side of each fixed plate 22 and are fixed to each other. In this embodiment, the connecting plate 23 is configured toward the bottom of the insulating base 10, while the first connecting plate 24 and the second connecting plate 25 are configured toward the wiring hole 13 and the top of the insulating base 10, but the present application is not limited to this. The connecting plate 23 can also be configured toward the wiring hole 13 and the top of the insulating base 10, while the first connecting plate 24 and the second connecting plate 25 are configured toward the bottom of the insulating base 10. Accordingly, the connecting plate 23, the first connecting plate 24, the second connecting plate 25 and each fixed plate 22 form a hollow rectangular frame and together enclose an installation space 221. In addition, the first connecting plate 24 has a fitting block 241, and the second connecting plate 25 has a fitting groove 251. The engaging block 241 is inserted into the engaging groove 251, thereby interlocking and securing the first joining plate 24 and the second joining plate 25. Thus, because the connecting plate 23, the first joining plate 24, the second joining plate 25, and the fixing plates 22 together form a rectangular frame, the overall structure of the conductive base 20 is stable and not susceptible to distortion, thereby ensuring that the leaf spring assembly 30 can be accurately assembled and securely positioned.

[0068] Refer back Figures 2 to 5As shown, the number of abutment blocks 222 on each fixed plate 22 corresponds to the number of spacings between the corresponding support ribs 323. That is, in this embodiment, each fixed plate 22 has three abutment blocks 222, so that each clamping leaf spring 322 can abut against each abutment block 222 at a corresponding position. In this embodiment, each abutment block 222 is stamped from the outer side of the fixed plate 22 (i.e., the side away from the installation space 221), so that the inner side (the side facing the installation space 221) protrudes to form the abutment block 222. Therefore, the abutment block 222 remains completely connected to the corresponding fixed plate 22 and does not separate.

[0069] However, this application is not limited to the above embodiments. Please refer to Figures 6 to 8 The second embodiment of the present application is shown in FIG. The main difference between the second embodiment and the first embodiment is that each abutment block 222 is stamped from the outside of the fixed plate 22 (i.e., the side away from the installation space 221), thereby causing the fixed plate 22 to break and form an abutment block 222 with one end connected to the fixed plate 22 and one end separated from the fixed plate 22. Of course, the present application is not limited to these two forms of abutment blocks 222. This is only used as an illustration to enable those with ordinary knowledge in the field to understand and implement it accordingly, but it is not used to limit the present application. Therefore, as long as there is an abutment block 222 protruding from the side of the fixed plate 22 facing the installation space 221, it should fall within the scope of protection of the present application, and this is hereby stated.

[0070] The power connector of the present application has an abutment block 222 protruding toward the installation space 221 through the fixing plate 22, and has a plurality of clamping leaf springs 322 whose ends abut against the corresponding abutment blocks 222 through the elastic clamping portion 32, so that when the tongue plate A is inserted into the insertion space 321 from the socket 12 and is elastically clamped by each clamping leaf spring 322, each clamping leaf spring 322 can be firmly abutted against each abutment block 222 without shaking or excessive deformation, thereby effectively increasing the clamping stability of each clamping leaf spring 322 on the tongue plate A, and avoiding structural elastic fatigue and deformation failure of each clamping leaf spring 322, thereby improving the current conduction effect of each clamping leaf spring 322.

[0071] In summary, the foregoing disclosure of this application is intended to enable those skilled in the art to clearly understand the technical content of this application and implement it accordingly, and is not intended to limit the scope of patent protection of this application. In addition, this application may of course have many other embodiments not listed here. Without departing from the spirit and substance of this application, those skilled in the art should be able to develop various corresponding changes and modifications based on this application, and these corresponding changes and modifications should fall within the scope of protection of the patent applied for in this application.
