Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector socket assembly and an energy storage connector. Background Art

[0002] Energy storage connectors, as a type of electrical connector, are widely used in the field of energy storage. Existing energy storage connectors generally include a plug assembly and a socket assembly, which can achieve electrical connection after being plugged in. Figure 1 and Figure 2 As shown, the socket assembly includes a conductive component 100, a socket housing 300, and a seal 200. The conductive component 100 is inserted into the socket housing 300, and the plastic housing 300 and seal 200 are secured by screws 500. A finger-proof cap 400 is mounted on the top of the conductive component 100. The conductive component 100 is a metal pin and is secured to the socket housing 300 by a snap-fit ​​structure. Because the conductive component 100 is provided with a bidirectional step to prevent axial movement, a corresponding snap-fit ​​structure is provided inside the socket housing 300 to secure the conductive component 100. This prevents axial movement, resulting in a complex structure, high machining precision requirements, a long machining cycle, and high costs. Furthermore, under long-term high-temperature operation, the snap-fit ​​of the conductive component 100 may break, causing the socket assembly to back out, ultimately leading to connector failure. Furthermore, existing socket assemblies require high dimensional accuracy for each component assembly; otherwise, the conductive component is prone to shaking and rotating, which can cause improper connection between the plug assembly and the socket assembly. In addition, the socket assembly usually uses an anti-touch finger cap to solve the problem of preventing electric shock of the socket unit. The anti-touch finger cap has the risk of being lost and cannot achieve the effect of preventing electric shock, resulting in a large number of parts in the socket assembly and cumbersome operation steps. Summary of the Invention

[0031] Reference Figure 3The connector socket assembly 1 of the embodiment of the present invention includes a conductive component 11 and a socket housing 12 integrally injection-molded with the conductive component 11. The conductive component 11 is disposed within the socket housing 12. The connector socket assembly is used for an energy storage connector. The conductive component 11 is an integrally formed metal pin. In this embodiment, the conductive component 11 is formed by machining a metal bar. The conductive component 11 includes a conductive component body 110 and a mounting portion 111 located at one end of the conductive component body 110. The end of the conductive component body 110 away from the mounting portion 111 is a hollow cylindrical structure. The mounting portion 111 is a flat structure. The mounting portion 111 is provided with a mounting hole 113, and a rivet nut 16 is installed in the mounting hole 113. By integrally injection-molding the conductive component 11 and the socket housing 12, this embodiment greatly reduces the complexity of the structural design of the conductive component itself in the existing socket assembly, making the processing of the conductive component 11 simpler. In addition, there is no need to provide an additional snap-fit ​​structure inside the socket housing 12 to fix the conductive component 11, which simplifies the structure of the socket housing 12 and significantly reduces the processing cost. Furthermore, it is easy to understand that the conductive component body 110 and the socket housing 12 are integrally injection-molded, which reduces the socket assembly's requirements for the dimensional accuracy of the conductive component parts and can effectively prevent abnormal phenomena such as shaking and rotation of the conductive component. The ultimate goal is to prevent abnormal contact between the plug assembly and the socket assembly when they are mated, and can improve the holding force of the conductive component, thereby improving the reliability and service life of the energy storage connector product.

[0032] Reference Figure 3 and Figure 4 , the side wall of the conductive component body 110 is provided with a hole 112. In this embodiment, the number of holes 112 is 1, and the hole 112 is an injection hole, which can allow the injection plastic to be filled into the interior of the conductive component body 110 to form a first core column 13. The top of the first core column 13 covers the top of the conductive component body 110 located on the front side of the plugging direction to form an anti-touch finger cap 131. In this way, the socket assembly is integrally injection-molded with an anti-touch finger cap, which solves the anti-electric shock function of a single socket assembly 1. This embodiment adopts in-mold injection molding to replace the anti-touch finger cap commonly used in the socket assembly of the existing energy storage connector (refer to Figure 1 The middle anti-touch finger cap 400) and the socket shell are formed as one piece, which reduces the number of parts in the socket assembly, simplifies the parts assembly steps, and is very helpful in reducing assembly costs.

[0033] In some embodiments, the first stem 13 is a hollow cylindrical structure with a consistent inner diameter from bottom to top. The top of the first stem 13 covers the top of the conductive component body 110 in the plugging direction, forming an anti-touch finger cap 131. It will be readily understood that the top of the anti-touch finger cap does not extend beyond the top of the socket housing 12 in the plugging direction. In some embodiments, the first stem 13 is a hollow cylindrical structure with a variable inner diameter. Specifically, the inner diameter d of the first stem 13 can be varied based on the socket assembly's functional requirements for preventing mis-insertion.

[0034] Reference Figure 3 The socket housing 12 includes an integrally formed base 120 and a docking portion 121 arranged on the side of the base 120 close to the plug assembly and connected to the plug assembly. A fixing screw 15 is integrally injection-molded or hot-pressed on the base 120. When the base 120 is installed on the panel, a seal 14 is provided between the side of the base 120 facing the docking portion 121 and the panel.

[0035] Reference Figure 5 An embodiment of the present invention further provides an energy storage connector, comprising the receptacle assembly 1 described in the above embodiment and a plug assembly 2 that plugs into the receptacle assembly 1. The plug assembly 2 comprises a plug housing 21, a conductive connection component 22, and a cable 26. The conductive connection component 22 is disposed within the plug housing 21 and includes a first conductive portion 220 and a second conductive portion 221. The first conductive portion 220 is hollow and cylindrical, with a female terminal crown spring 223 mounted therein. The second conductive portion 221 is plate-shaped. One end of the cable 26 is connected to the second conductive portion 221 of the conductive connection component 22 by ultrasonic welding or laser welding. In this embodiment, ultrasonic welding is used.

[0036] As described above, in some embodiments, the first core column 13 in the socket assembly 1 is a hollow cylindrical structure with a variable inner diameter, that is, the inner diameter dimension d of the first core column 13 can be changed according to the functional requirements of the socket assembly to prevent mis-insertion. Specifically, a second core column 212 is also correspondingly provided inside the plug shell 21 of the plug assembly 2. The top of the second core column 212 protrudes from the top of the first conductive portion 220 located on the front side of the plug-in direction. When the diameter dimension of the second core column 212 matches the inner diameter dimension d of the first core column 13, the plug assembly 2 and the socket assembly 1 are plugged into place; when the diameter dimension of the second core column 212 is greater than the inner diameter dimension d of the first core column 13, the plug assembly 2 and the socket assembly 1 cannot be plugged into place, achieving the effect of preventing mis-insertion and realizing the plug-in matching of different types of socket assemblies and plug assemblies.

[0037] Reference Figure 3 、 Figure 5 、 Figure 6 and Figure 7The plug housing 21 is provided with a hook 210 on its exterior along the insertion direction. The docking portion 121 of the receptacle housing 12 is provided with an annular groove 122 for engaging the hook 210. When the plug assembly 2 is mated with the receptacle assembly 1, the hook 210 engages within the annular groove 122, allowing the plug assembly 2 and the receptacle assembly 1 to rotate 360 ​​degrees after mating. The hook 210 consists of a snap-fit ​​portion 2101, a button portion 2102, and a connecting portion 2103. One end of the connecting portion 2103 is fixed between the snap-fit ​​portion 2101 and the button portion 2102, and the other end of the connecting portion 2103 is fixed to the plug housing 21. A mounting groove is provided between the button portion 2102 and the connecting portion 2103. A secondary locking block 211 is slidably inserted into the mounting groove along the insertion direction. The secondary lock block 211 has a locking position and an unlocking position in the sliding stroke. The secondary lock block 211 in the locking position is stuck at the bottom of the button part 2102, so that the button part 2102 cannot be pressed down, thereby realizing secondary locking to prevent accidental unlocking; the secondary lock block 211 in the unlocking position releases the limit on the button part 2102, thereby allowing the button part 2102 to be pressed down smoothly, so that the hook 210 disengages from the annular groove 122 to realize the unlocking of the plug assembly 2 and the socket assembly 1.

[0038] However, in daily use of the energy storage connector, after the plug assembly 1 and the socket assembly 2 are plugged in, the sound feedback of the hook 210 is used to determine whether they are plugged in properly. However, this judgment method may cause an abnormal situation in which the plug assembly 1 and the socket assembly 2 are not actually plugged in properly. Therefore, in some embodiments, reference is made to Figure 3 and Figure 7 A stopper 123 is provided on the outside of the docking portion 121 of the socket shell 12 near the base 120, and a hook 210 is provided on one side of the plug shell 21, the front end of which is located in the plugging direction and can form surface contact with the top of the stopper 123. The socket assembly 1 and the plug assembly 2 are plugged into place through visual operation, thereby improving the reliability of the energy storage connector.

[0039] In another embodiment, referring to Figure 8 , the conductive component 11' can also be formed by punching, bending and butting a metal plate, and the rest is the same as the above embodiment. Specifically, in this embodiment, the metal plate is punched and bent on both sides to butt together through the butt seam 1101 to form the conductive component 11'. The conductive component 11' includes a conductive component body 110' and a mounting portion 111' located at one end of the conductive component body 110'. The conductive component body 110' is a hollow cylindrical structure, and the upper and lower layers of the mounting portion 111' are riveted to each other to form a flat structure. The conductive component processing technology of this embodiment is simple, the production efficiency is high, and it is more conducive to reducing the processing cost of the energy storage connector.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
