Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and more particularly to a power connector. Background Technology
[0002] Existing power connectors primarily consist of a guide plate structure and a spring structure housed within an insulating shell. The spring structure, mounted on the guide plate, clamps the connector's tongue to form an electrical connection for power transmission. However, due to the spring structure's inherent elasticity in clamping the connector's tongue, the tongue is prone to wobbling under stress. This can cause compression on one side of the spring structure, leading to poor contact on the other side and affecting current conduction. Furthermore, under prolonged use, existing spring structures are susceptible to deformation due to repeated deformation loads, resulting in a decrease in the normal pressure at the contact point between the spring and the guide plate, further impacting current conduction.
[0003] In view of this, the creator has devoted himself to researching and applying theoretical principles to address the shortcomings of the existing technology, and has made every effort to solve the aforementioned problems, which has become the creator's goal for improvement.

Each first turning point is used to abut against the periphery of the tongue plate, and each second turning point is used to abut against the conductive base.
[0012] In one embodiment of the present invention, each fixing plate has an abutment block, each abutment block protruding from the corresponding fixing plate toward another fixing plate, and the ends of each clamping leaf spring corresponding to each fixing plate abut against each abutment block.
[0013] In one embodiment of the present invention, the conductive base further includes a connecting plate, a first joining plate and a second joining plate. The connecting plate is connected to one side of each fixed plate, and the first joining plate and the second joining plate extend from the other side of each fixed plate and are engaged and fixed to each other.

[0014] In one embodiment of the present invention, the first joining plate has a fitting block, the second joining plate has a fitting groove, and the fitting block is embedded in the fitting groove.

[0027] The detailed description and technical content of this utility model will be explained in conjunction with the drawings below. However, the drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.
[0028] This utility model provides a power connector that allows the tongue plate A of a mating connector (not shown) to be inserted and overlapped to form an electrical connection for power transmission. Please refer to... Figures 1 to 4 As shown, the power connector of this utility model includes an insulating base 10, a conductive base 20, and an elastic clamping assembly 30.
[0029] In this embodiment, the insulating base 10 is integrally molded from plastic injection molding, but this invention is not limited to this. For example, the insulating base 10 can also be made of other insulating materials or manufactured using other plastic processing methods. The insulating base 10 has a receiving space 11, a socket 12, and a wiring hole 13. The receiving space 11 is located inside the insulating base 10 and is used to house the conductive base 20. The socket 12 and the wiring hole 13 extend from the surface of the insulating base 10 toward its interior to the receiving space 11, that is, the receiving space 11 can be connected to the external space through the socket 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 receiving space 11, while the socket 12 extends horizontally inward from the side of the insulating base 10 to the receiving space 11. However, this invention is not limited to this, and the position and direction of the wiring hole 13 and the socket 12 can be adjusted according to different needs. It is worth mentioning that the wiring hole 13 is used to insert a power cable (not shown) to communicate with the conductive base 20, while the socket 12 is used to insert the tongue plate A of the mating connector.
[0030] In this embodiment, the conductive base 20 is an integral metal part with good conductivity, but this utility model is not limited to this, and the conductive base 20 can also be made of other materials with good conductivity. The conductive base 20 is disposed within the accommodating space 11. Specifically, the insulating base 10 can be embedded and injected to accommodate the conductive base 20 within the accommodating space 11, or the conductive base 20 can be inserted and fixed within the accommodating space 11. This utility model does not impose any restrictions on this. The conductive base 20 mainly includes a wiring guide plate 21 and a pair of parallel fixing plates 22. The wiring guide plate 21 is connected to each fixing plate 22, and the wiring guide plate 21 extends away from the socket 12 so that the wiring hole 13 is configured corresponding to the wiring guide plate 21. More specifically, the wiring guide plate 21 is perpendicular to the setting direction of the wiring hole 13. Therefore, when the power cable is inserted through the wiring hole 13, it can abut against the wiring guide plate 21 in the accommodating space 11 to form an electrical connection and transmit power to the conductive base 20. In this embodiment, each fixing plate 22 is substantially perpendicular to the wiring guide plate 21, but the present invention is not limited thereto.
[0031] In this embodiment, the elastic clamping assembly 30 is an integral metal part with good electrical conductivity, but the present invention is not limited to this, and the elastic clamping assembly 30 can also be made of other materials with good electrical conductivity. The elastic clamping assembly 30 mainly includes a base 31 and a plurality of clamping leaf springs 32. The base 31 is disposed between each fixing plate 22, and the base 31 surrounds and forms an insertion space 311. Specifically, the base 31 is generally rectangular and can surround the insertion space 311. Each clamping leaf spring 32 extends from the base 31 toward the insertion space 311, and each clamping leaf spring 32 is arranged around the perimeter of the insertion space 311.
[0032] Please refer to this. Figures 5 to 8 As shown, when the tongue plate A is inserted into the insertion space 311 through the insertion hole 12, each clamping leaf spring 32 can jointly and firmly clamp the tongue plate A around its perimeter to prevent the tongue plate A from detaching. This effectively increases the clamping stability of each clamping leaf spring 32 on the tongue plate A, thereby improving the normal pressure at each contact point when each clamping leaf spring 32 clamps the tongue plate A. It can also prevent the elastic clamping assembly 30 from undergoing structural deformation and failure, while limiting the sway range of the tongue plate A so that each clamping leaf spring 32 is subjected to uniform force, thereby improving the current conduction effect of each clamping leaf spring 32.
[0033] Further explanation: The base 31 of the elastic clamping assembly 30 includes a connecting section 312, a pair of side sections 313, and an extension section 314. The side sections 313 are arranged parallel to each other. The connecting section 312 connects to each side section 313 and is located at one end of each side section 313. The extension section 314 extends from the other end of one side section 313 towards the other side section 313. In this embodiment, the extension section 314 does not connect to the side section 313 after extending from one side section 313 towards the other. This structure is due to the manufacturing process of the elastic clamping assembly 30. However, in other embodiments, the extension section 314 may connect between two side sections 313, and this invention does not limit this. The connecting section 312, each side section 313, and the extension section 314 are generally rectangular and together enclose an insertion space 311. Furthermore, in this embodiment, each side segment 313 is configured corresponding to each fixed plate 22, while the connecting segment 312 and the extension segment 314 are configured between each fixed plate 22. However, this utility model is not limited to this. For example, in other embodiments, the connecting segment 312 and the extension segment 314 may also be configured corresponding to each fixed plate 22, while each side segment 313 may be configured between each fixed plate 22.
[0034] See also Figures 2 to 5 As shown, the elastic clamping assembly 30 also includes a pair of latching claws 33. Each latching claw 33 is disposed opposite to each other on opposite sides of the base 31, and each latching claw 33 is respectively engaged with the end of each fixing plate 22. In this embodiment, each latching claw 33 is respectively disposed on each side segment 313, but in other embodiments it may also be disposed on the connecting segment 312 and the extension segment 314. Each latching claw 33 includes an attachment plate 331 and a barb 332. In each latching claw 33, the attachment plate 331 extends from the base 31 by bending and is attached to the end face of the corresponding fixing plate 22 facing the insertion hole 12. The barb 332 in each latching claw 33 extends from its attachment plate 331 by bending and is engaged with the side of the corresponding fixing plate 22 away from the base 31. In this way, the elastic clamping assembly 30 is fixed to the conductive base 20 by each of the latching claws 33 engaging with the ends of the fixing plates 22. In this embodiment, each latching claw 33 has four barbs 332, but this invention is not limited to this, and the number of barbs 332 in each latching claw 33 can be adjusted according to different needs.
[0035] Furthermore, each clamping leaf spring 32 includes a transition extension 321, a first inclined section 322, a second inclined section 323, and an abutment section 324. In each clamping leaf spring 32, the transition extension 321 extends from the base 31 along the insertion direction of the tongue plate A, and the transition extension 321 forms a gap (not labeled) between itself and the conductive seat 20 to serve as a collapsing space for deformation of the clamping leaf spring 32 when the tongue plate A is inserted. The first inclined section 322 extends inclinedly from the end of the transition extension 321 away from the base 31 toward the insertion space 311. The second inclined section 323 extends inclinedly from the end of the first inclined section 322 away from the first inclined section 322 toward the direction away from the insertion space 311. The abutment section 324 extends inclinedly from the end of the second inclined section 323 away from the base 31 toward the insertion space 311. Thus, each clamping leaf spring 32 is generally lightning-shaped and has at least two bends. Specifically, a first turning point is formed between the first inclined segment 322 and the second inclined segment 323 of each clamping leaf spring 32, and a second turning point is formed between the second inclined segment 323 and the abutment segment 324 of each clamping leaf spring 32. Each first turning point is used to abut against the periphery of the tongue plate A, and each second turning point is used to abut against the conductive base 20, thereby providing a supporting force for each clamping leaf spring 32 to clamp the tongue plate A.
[0036] To further explain, each fixing plate 22 has at least one abutment block 221. Each abutment block 221 protrudes from its corresponding fixing plate 22 toward another fixing plate 22. In this embodiment, each fixing plate 22 has two abutment blocks 221, but this invention is not limited to this; for example, each fixing plate 22 may have only one or more abutment blocks 221. Thus, when the tongue plate A is inserted into the insertion space 311 through the insertion hole 12, the ends of each clamping leaf spring 32 corresponding to each fixing plate 22 will abut against each abutment block 221 due to the elastic deformation of each clamping leaf spring 32, thereby limiting the extension and deformation space of each clamping leaf spring 32, and allowing each clamping leaf spring 32 to firmly abut against each abutment block 221 without shaking or excessive deformation. In addition, since each of the latches 33 of the elastic clamping assembly 30 is engaged with the end of each of the fixed plates 22, the end of each abutting section 324 of each clamping spring 32 is engaged with each abutting block 221 of each of the fixed plates 22, and the second turning point of each clamping spring 32 is engaged with each of the fixed plates 22, the elastic clamping assembly 30 can also be stably mounted on the conductive base 20, thereby allowing each clamping spring 32 to stably clamp the tongue plate A and effectively limit the tongue plate A to prevent the tongue plate A from shaking.
[0037] See also Figure 2 and Figure 3As 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 fixing plate 22, and the first connecting plate 24 and the second connecting plate 25 extend from the other side of each fixing plate 22 and are engaged and fixed to each other. In this embodiment, the connecting plate 23 is arranged facing the bottom of the insulating base 10, while the first connecting plate 24 and the second connecting plate 25 are arranged facing the wiring hole 13 and the top of the insulating base 10. However, this utility model is not limited to this, and the connecting plate 23 may also be arranged facing the wiring hole 13 and the top of the insulating base 10, while the first connecting plate 24 and the second connecting plate 25 may be arranged facing the bottom of the insulating base 10. Accordingly, the connecting plate 23, the first connecting plate 24, the second connecting plate 25, and each fixing plate 22 form a hollow rectangular frame that together surrounds the base 31. Furthermore, the first connecting plate 24 has a fitting block 241, and the second connecting plate 25 has a fitting groove 251. The interlocking block 241 is embedded in the interlocking groove 251, thereby engaging and fixing the first connecting plate 24 and the second connecting plate 25 together. In this way, since the connecting plate 23, the first connecting plate 24, the second connecting plate 25 and each fixing plate 22 together form a rectangular frame, the overall structure of the conductive base 20 is stable and not prone to twisting or deformation, thereby ensuring that the elastic clamping assembly 30 can be accurately assembled and stably positioned.
[0038] The power connector of this utility model has a base 31 disposed between each fixing plate 22 and forming an insertion space 311. Each clamping leaf spring 32 extends from the base 31 toward the insertion space 311, so that when the tongue plate A is inserted into the insertion space 311 through the insertion hole 12, each clamping leaf spring 32 can elastically clamp the tongue plate A around its perimeter. This effectively increases the clamping stability of each clamping leaf spring 32 on the tongue plate A and improves the overall structural strength of the elastic clamping assembly 30.
[0039] In summary, the foregoing disclosure of this utility model is intended to enable those skilled in the art to clearly understand the technical content of this utility model and implement it accordingly, and is not intended to limit the scope of patent protection of this utility model. In addition, this utility model may of course have other embodiments not listed. Without departing from the spirit and essence of this utility model, those skilled in the art should be able to devise various corresponding changes and modifications based on this utility model, but all such corresponding changes and modifications should fall within the scope of protection of the patent application filed for this utility model.
