Abstract
Description
Connector socket assembly Technical Field
[0001] The present application relates to the field of connector technology, and in particular to a connector socket assembly. Background Art
[0002] Energy storage connectors, a type of electrical connector, are widely used in the energy storage field. Existing energy storage connectors generally include a plug assembly and a socket assembly, which, when plugged together, establish an electrical connection. As shown in Figures 1 and 2, 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 the seal 200 are secured by screws 500. A finger-proof cap 400 is mounted on top of the conductive component 100. The conductive component 100 is a metal pin and is secured to the socket housing 300 via a snap-fit mechanism. Since 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 fix the conductive component 100 to prevent axial movement of the conductive component 100. As a result, the conductive component 100 itself has a complex structure, high processing precision requirements, a long processing cycle, and high costs. Moreover, the conductive component 100 may break under long-term high-temperature conditions, causing the socket assembly to withdraw, ultimately leading to connector failure. At the same time, existing socket assemblies have high assembly dimensional accuracy requirements for each part, otherwise the conductive component is prone to shaking and rotating abnormalities, which in turn causes abnormal 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 anti-electric shock effect, resulting in a large number of parts in the socket assembly and cumbersome operation steps. Summary of the Invention
[0003] The present application provides a connector socket assembly that can simplify the structure of conductive components, reduce the number of parts in the socket assembly, reduce the complexity of the processing process, and ultimately reduce manufacturing costs.

[0030] Referring to Figure 3, the connector receptacle assembly 1 of the present embodiment includes a conductive component 11 and a receptacle housing 12 integrally injection-molded with the conductive component 11. The conductive component 11 is disposed within the interior of the receptacle housing 12. 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 distal from the mounting portion 111 is a hollow cylindrical structure. The mounting portion 111 is flat and has a mounting hole 113 disposed therein. A rivet nut 16 is mounted within the mounting hole 113. By integrally injection-molding the conductive component 11 and the receptacle housing 12, this embodiment significantly reduces the structural complexity of the conductive component in existing receptacle assemblies, further simplifying the processing of the conductive component 11. Furthermore, no additional snap-fit structure is required within the receptacle housing 12 to secure the conductive component 11. This simplifies the structure of the receptacle housing 12 and significantly reduces processing costs. 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.
[0031] 3 and 4 , a hole 112 is provided on the side wall of the conductive component body 110 . In this embodiment, the number of the hole 112 is one, and the hole 112 is an injection hole, which enables 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 provided with an anti-touch finger cap through integral injection molding, thereby solving the anti-electric shock function of a single socket assembly 1 . This embodiment adopts in-mold injection molding to integrate the two plastic parts, the anti-touch finger cap commonly used in the socket assembly of the existing energy storage connector (refer to the anti-touch finger cap 400 in FIG. 1 ), and the socket shell, thereby reducing the number of parts of the socket assembly, simplifying the parts assembly steps, and being very helpful in reducing assembly costs.
[0032] 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.
[0033] 3 , the socket housing 12 includes an integrally formed base 120 and a docking portion 121 disposed on a 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 mounted on a panel, a seal 14 is disposed between the panel and the side of the base 120 facing the docking portion 121.
[0034] Referring to Figure 5 , an embodiment of the present application further provides an energy storage connector, comprising the socket assembly 1 described in the above embodiment and a plug assembly 2 that is pluggable with the socket 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.
[0035] 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 1 and the socket assembly 2 are plugged into place; when the diameter dimension of the second core column 212 is larger than the inner diameter dimension d of the first core column 13, the plug assembly 1 and the socket assembly 2 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.
[0036] Referring to Figures 3, 5, 6, and 7, a hook 210 is provided on the exterior of the plug housing 21 along the insertion direction. An annular groove 122 for engaging the hook 210 is provided on the docking portion 121 of the receptacle housing 12. 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 comprises 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, into which a secondary locking block 211 is slidably inserted 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 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 2102 and allows the button 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.
[0037] 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 properly plugged in. However, this judgment method may cause the plug assembly 1 and the socket assembly 2 to be not actually properly plugged in, so in some embodiments, referring to Figures 3 and 7, a stopper 123 is provided on the docking portion 121 of the socket shell 12 near the outside of the base 120, and the front end of the side of the plug shell 210 located in the plugging direction can form a surface contact with the top of the stopper 123, so that the socket assembly 1 and the plug assembly 2 are plugged in place through visual operation, thereby improving the reliability of the energy storage connector.
[0038] In another embodiment, referring to FIG8 , the conductive component 11 'can also be formed by stamping, bending, and butting a metal plate, and the rest is the same as the above embodiment. Specifically, in this embodiment, the metal plate is stamped and bent on both sides to butt together through a butt joint 1101 to form the conductive component 11 '. The conductive component 11 ' comprises 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, and the production efficiency is high, which is more conducive to reducing the processing cost of the energy storage connector.
[0039] Obviously, the above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application, and are not intended to limit the embodiments of the present application. A person skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present application. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the claims of the present application.
