Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a plug-in assembly, a wire connection structure having a plug-in assembly, and a lighting fixture having a plug-in assembly. Background Technology

[0002] In existing metal plug manufacturing processes, the connector base is typically produced using external injection molding. This method requires the connector base to completely enclose the outer circumference of the metal plug to ensure electrical insulation and mechanical strength. However, in practice, one-piece injection molding has the following drawbacks:

[0003] 1. Uneven thickness of the glue: Due to limitations in mold design or material flowability, the joint seat after injection molding may have uneven wall thickness in some areas. This not only affects the appearance quality of the product, but more importantly, it may weaken the mechanical strength of key parts.

[0004] 2. Shrinkage problem: During the cooling and curing process, the plastic material may shrink, resulting in the finished product size not matching the design. This shrinkage phenomenon is more obvious for thinner wall parts, which in turn affects the effect of the connector on the internal metal plug and the overall structural stability.

[0005] 3. Difficult to correct through secondary molding: Once the above problems are discovered, due to the inherent characteristics of injection molded parts, it is difficult to improve these defects through secondary processing, which increases production costs and time and reduces the yield rate.

[0006] In addition, the traditional one-piece injection molding method also makes product design inflexible and makes it difficult to easily adjust or optimize the specific structural features of the connector. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mating assembly, in which the connector seat is designed as two half-shells joined together, solving the problems of uneven wall thickness and shrinkage in traditional one-piece injection molding, improving the mechanical strength and electrical safety of the product. Furthermore, the positioning post and positioning groove ensure precise assembly, the annular ring enhances structural stability, and the fasteners ensure a secure connection.

[0008] This utility model also proposes a wire connection structure and a lighting fixture having the above-mentioned plug-in components.

[0009] The interlocking assembly according to this utility model includes:

[0010] The first connector seat includes a first half shell and a second half shell. The first half shell and the second half shell are assembled in opposite directions to form a first limiting groove. A male plug is provided in the first limiting groove, and the end of the male plug extends out of the first connector seat.

[0011] The second connector is connected to the first connector. The second connector includes a third half-shell and a fourth half-shell. The third half-shell and the fourth half-shell are assembled opposite each other to form a second limiting groove. A female socket is provided in the second limiting groove, and the male plug can be inserted into the female socket for communication.

[0012] The mating assembly described in this utility model has at least the following beneficial effects: It successfully overcomes the problems of uneven wall thickness and shrinkage commonly found in traditional one-piece injection molding processes. Under traditional manufacturing methods, due to limitations in the fluidity of injection molding materials and mold design, it is often difficult to ensure that the wall thickness of each part of the connector is consistent. This not only affects the appearance quality of the product, but more importantly, it weakens the mechanical strength of key parts, reducing the reliability and safety of the product. In addition, the shrinkage phenomenon that occurs during the cooling and solidification process of the injection molded part may cause the finished product dimensions to deviate from the design, especially for thinner wall parts, where this shrinkage phenomenon is more significant, thus affecting the mating assembly. The internal metal plug's enclosure effect and overall structural stability are addressed by designing the first and second connectors as two half-shells assembled together. This allows for independent control of the wall thickness of each half-shell during manufacturing, ensuring ideal thickness and strength distribution and preventing reliability degradation due to localized thinning. Furthermore, the opposing assembly to form a limiting groove to accommodate the male plug or female socket not only ensures adequate protection of the internal conductive components but also guarantees precise fit between the plug and socket. Simultaneously, this structural design simplifies the manufacturing process, making production more flexible and controllable, reducing defect rates, and increasing yield.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] In existing metal plug manufacturing processes, the connector base is typically produced using external injection molding. This method requires the connector base to completely enclose the outer circumference of the metal plug to ensure electrical insulation and mechanical strength. However, in practice, one-piece injection molding has the following drawbacks:

[0043] 1. Uneven thickness of the glue: Due to limitations in mold design or material flowability, the joint seat after injection molding may have uneven wall thickness in some areas. This not only affects the appearance quality of the product, but more importantly, it may weaken the mechanical strength of key parts.

[0044] 2. Shrinkage problem: During the cooling and curing process, the plastic material may shrink, resulting in the finished product size not matching the design. This shrinkage phenomenon is more obvious for thinner wall parts, which in turn affects the effect of the connector on the internal metal plug and the overall structural stability.

[0045] 3. Difficult to correct through secondary molding: Once the above problems are discovered, due to the inherent characteristics of injection molded parts, it is difficult to improve these defects through secondary processing, which increases production costs and time and reduces the yield rate.

[0046] In addition, the traditional one-piece injection molding method also makes product design inflexible and makes it difficult to easily adjust or optimize the specific structural features of the connector.

[0047] Therefore, such as Figures 1 to 3As shown, the plug-in assembly proposed in this utility model includes a first connector 100 and a second connector 200 that mates with the first connector 100. The first connector 100 includes a first half-shell 110 and a second half-shell 120, and the second connector 200 includes a third half-shell 210 and a fourth half-shell 220. Specifically, the first half-shell 110 and the second half-shell 120 are assembled opposite each other to form a first limiting groove 101. A male plug 1011 is provided in the first limiting groove 101, and the end of the male plug 1011 extends out of the first connector 100. Similarly, the third half-shell 210 and the fourth half-shell 220 are assembled opposite each other to form a second limiting groove 201. A female socket 2011 is provided in the second limiting groove 201, and the male plug 1011 and the female socket 2011 can be plugged in and connected. In response, the problem of uneven wall thickness and shrinkage, which are common in traditional one-piece injection molding processes, has been successfully overcome. Under traditional manufacturing methods, due to the limitations of injection material flow and mold design, it is often difficult to ensure that the wall thickness of each part of the connector is consistent. This not only affects the appearance quality of the product, but more importantly, it weakens the mechanical strength of key parts and reduces the reliability and safety of the product. In addition, the shrinkage phenomenon that occurs during the cooling and solidification process of the injection molded part may cause the finished product size to be inconsistent with the design. This shrinkage phenomenon is more significant for thinner wall parts, thus affecting the encapsulation effect of the connector on the internal metal plug and the overall structural stability. It should be noted that by designing the first connector 100 and the second connector 200 as two half-shells assembled together, the wall thickness of each half-shell can be independently controlled during manufacturing, ensuring an ideal thickness and strength distribution and avoiding a decrease in reliability due to local thinning. Furthermore, by assembling them in opposite directions to form a limiting groove to accommodate the male plug 1011 or the female socket 2011, this design not only ensures that the internal conductive components are fully protected, but also ensures precise matching between the plug and the socket. At the same time, this structural design simplifies the manufacturing process, making the production process more flexible and controllable, reducing the defect rate, and improving the yield.

[0048] Refer to Figure 3In some embodiments of this utility model, a first positioning post 111 is provided on the end face of the first half-shell 110 facing the second half-shell 120, and a first positioning groove corresponding to the first positioning post 111 is provided on the second half-shell 120. The first positioning post 111 and the first positioning groove are interlocked to ensure precise alignment between the first half-shell 110 and the second half-shell 120. This positioning mechanism not only simplifies the assembly process and improves production efficiency, but also significantly enhances the overall structural stability of the first connector seat 100. In practical applications, even in the face of frequent insertion and removal operations or external vibrations, the two half-shells can still maintain a tight connection, avoiding functional failure or poor connection problems caused by positional deviation. In addition, the cooperation between the first positioning post 111 and the first positioning groove facilitates automated production and quality control, reduces the need for manual adjustment, and thus improves the yield and consistency of the product. Similarly, a second positioning post 211 is provided on the end face of the third half-shell 210 facing the fourth half-shell 220, and a second positioning groove corresponding to the second positioning post 211 is provided on the fourth half-shell 220. The second positioning post 211 and the second positioning groove are inserted into each other. In this way, not only is the structural strength of the second connector seat 200 enhanced, but it also helps to improve assembly speed and accuracy, reduce the possibility of assembly errors, and further improve overall production efficiency and product quality.

[0049] Refer to Figure 2 and Figure 3 In some embodiments of this invention, the outer peripheral wall of the first connector 100 is provided with friction grooves 102 to facilitate gripping and inserting / removing the first connector 100, significantly improving the user's grip experience during insertion and removal operations. It is readily understood that the friction grooves 102 increase surface friction, allowing the user to grip the first connector 100 more easily and firmly, especially in humid environments or when hands are sweaty, improving operational safety and convenience. Furthermore, the friction grooves 102 also serve a decorative purpose, making the product more aesthetically pleasing and meeting modern consumers' demands for a balance between functionality and aesthetics. In some embodiments, the outer peripheral wall of the second connector 200 is similarly provided with friction grooves to facilitate a firm gripping of the second connector 200 by the user.

[0050] Refer to Figure 4 and Figure 5In some embodiments of this utility model, the mating assembly further includes a first annular ring 300. The first annular ring 300 can tightly bind the first connector seat 100, further improving the firmness of the first half-shell 110 and the second half-shell 120 after assembly, effectively preventing the first half-shell 110 and the second half-shell 120 from loosening or separating when subjected to external impact or vibration, and ensuring the reliability of the internal electrical connection. In addition, the application of the first annular ring 300 simplifies the assembly process, improves production efficiency, and also facilitates disassembly and maintenance, reducing maintenance costs. It does not require complex tools or processes, making it suitable for large-scale production applications, and also provides users with a robust and easy-to-operate connection solution. Specifically, the outer peripheral wall of the first half-shell 110 is provided with a first mounting half-groove, and the outer peripheral wall of the second half-shell 120 is provided with a second mounting half-groove that corresponds to and fits into the first mounting half-groove. The first annular ring 300 can fit into the first mounting half-groove and the second mounting half-groove to fix the first half-shell 110 and the second half-shell 120. Similarly, the mating assembly also includes a second annular ring 400. Specifically, the outer peripheral wall of the third half-shell 210 is provided with a third mounting half-groove, and the outer peripheral wall of the fourth half-shell 220 is provided with a fourth mounting half-groove that corresponds to and engages with the third mounting half-groove. The second annular ring 400 can be fitted into the third and fourth mounting half-groos to fix the third half-shell 210 and the fourth half-shell 220. The function of the second annular ring 400 on the second connector seat 200 is similar to the function of the first annular ring 300 on the first connector seat 100, and will not be described in detail here.

[0051] Furthermore, refer to Figure 4 The mating assembly also includes a retaining member 500, which is fitted onto the mating point of the first connector 100 and the second connector 200. Both ends of the retaining member 500 are respectively engaged with the first connector 100 and the second connector 200 to secure them, effectively improving the stability of the connection and preventing loosening. This ensures the mating assembly remains tightly connected during use, even under external tension. Furthermore, the retaining member 500 not only strengthens the overall mechanical strength of the assembly but also provides a clear locking indicator, allowing the user to clearly see whether the connection has been correctly established.

[0052] Furthermore, the fastener 500 can also cooperate with the first annular ring 300 and the second annular ring 400, so that the first annular ring 300, in addition to fixing the first connector 100, can also seal the connection between the male plug 1011 and the female socket 2011; similarly, in addition to fixing the second connector 200, the second annular ring 400 can also seal the connection between the male plug 1011 and the female socket 2011; thus, the first annular ring 300 and the second annular ring 400 work together to provide a waterproof seal on both sides of the connection between the male plug 1011 and the female socket 2011. Specifically, refer to... Figure 4 The two sides of the first annular ring 300 abut against the inner circumferential surface of the fixing member 500 and the outer circumferential surface of the first connector seat 100, respectively. The two sides of the second annular ring 400 abut against the inner circumferential surface of the fixing member 500 and the outer circumferential surface of the second connector seat 200, respectively. At this time, both the first annular ring 300 and the second annular ring 400 can function as sealing rings, helping to improve waterproof and dustproof performance and extend the product's service life.
