Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically, to a rectangular short-circuit socket and an electrical connector. Background Technology

[0002] In applications such as circuit testing and system maintenance, short-circuit sockets are commonly used functional devices. Their function is to reliably short-circuit multiple circuit contacts together to achieve a specific electrical function. Currently, common short-circuit sockets typically utilize existing components, connecting them at their ends through methods such as welding or crimping to achieve the short-circuit function. However, this existing short-circuit socket structure has significant drawbacks, resulting in high production costs, long manufacturing cycles, and poor economic efficiency, making it difficult to meet the market's urgent demand for low-cost, high-reliability products. Specifically, the shortcomings of existing technology are mainly reflected in the following aspects:

[0003] First, the product structure is complex, resulting in low assembly efficiency. Existing short-circuit sockets typically consist of numerous components, including a housing, multiple contacts, and connecting parts. This complex structure leads to cumbersome assembly processes, often requiring specialized positioning fixtures to ensure accurate alignment and assembly of the components. This not only increases the complexity of the production process but also reduces production efficiency.

[0004] Secondly, the manufacturing cost is high and the production cycle is long. On the one hand, to achieve good conductivity, multiple contacts need to be electroplated with precious metals such as gold, resulting in high material costs. On the other hand, the socket housing is usually made of aluminum alloy through machining. This process itself has a high material removal rate and is costly. After machining, multiple post-processing steps such as deburring, polishing, and surface electroplating, such as nickel plating, are required, which greatly extends the production cycle. In addition, surface treatments such as electroplating are special processes, and their quality is difficult to control. If quality problems occur during the process, the entire component base can easily be scrapped, resulting in significant quality losses and economic waste.

[0005] In summary, existing short-circuit sockets, due to their inherent structural design and manufacturing process limitations, are no longer able to meet the demands of market competition in terms of cost and efficiency. Therefore, there is an urgent need in this field for a new technical solution that can fundamentally simplify the structure and optimize the process, effectively reducing production costs and shortening the manufacturing cycle while ensuring reliable electrical performance. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to provide a rectangular short-circuit socket and an electrical connector for short-circuit protection between the contacts of a multi-core rectangular electrical connector plug, thereby enhancing equipment safety during transportation. This short-circuit socket features a simple and reliable structure, convenient operation, and low processing difficulty.

[0007] The present invention solves the above problems through the following technical solution:

[0008] A rectangular short-circuit socket includes: a socket housing, an L-shaped locking accessory, and several sockets. The socket housing has an integrally formed socket base, and the entire structure is made of engineering plastic and is formed into a one-piece structure by injection molding. The socket base inside the socket housing has a first cavity and a second cavity formed on the left and right sides. Several sockets are disposed inside the socket housing with their ends penetrating through the socket base, and the ends of the sockets are respectively located in the first cavity and the second cavity. Socket lugs are formed on opposite sides of the socket housing. The L-shaped locking accessory cooperates with the socket lugs for installing the short-circuit socket.

[0009] As a further improvement, the engineering plastic is any one of polyetheretherketone, polyphenylene sulfide, nylon, or polybutylene terephthalate.

[0010] As a further improvement, the L-shaped locking accessory is embedded in an integrated structure during the injection molding process.

[0011] As a further improvement, the socket housing is rectangular, and the socket lugs are located on the shorter side of the rectangular socket housing.

[0012] As a further improvement, the tail end of the insertion hole in the second cavity is soldered and then potted, so that the volume of the second cavity is a potting cavity for potting the tail end of the insertion hole.

[0013] As a further improvement, the number of the sockets is 2 to 36, and they are arranged in multiple rows.

[0014] As a further improvement, the socket is made of tin bronze.

[0015] As a further improvement, the surface of the socket is gold-plated.

[0016] As a further improvement, the L-shaped locking accessory is made of 304 stainless steel.

[0017] Furthermore, this utility model also solves the above problems through the following technical solutions:

[0018] An electrical connector, comprising a rectangular short-circuit socket as described above.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Combined with appendix Figure 1-2 As shown, a rectangular short-circuit socket includes: a socket housing 1, an L-shaped locking accessory 2, and several socket holes 4. The socket housing 1 has an integrally formed socket base 3, and the entire structure is made of engineering plastic through injection molding, forming a single engineering plastic part. This shortens the processing cycle and avoids the risks associated with surface treatment. The material can be high-performance, high-heat-resistant polyetheretherketone (PEEK), polyphenylene sulfide (PPS), or cost-effective, versatile nylon (PA) or polybutylene terephthalate (PBT), etc.; preferably, it is polyphenylene sulfide (PPS). Furthermore, the socket housing 1 has a first cavity 11 and a second cavity 12 formed by the slots on the left and right sides of the socket base 3. The second cavity 12 is smaller than the first cavity 11. Several socket holes 4 are disposed inside the socket housing 1 with their ends penetrating through the socket base 3, and the ends of the socket holes 4 are respectively located in the first cavity 11 and the second cavity 12. Socket lugs 13 are formed on opposite sides of the outside of the socket housing 1 for cooperating with the L-shaped locking accessory 2 to install the short-circuit socket through the L-shaped locking accessory 2. Preferably, it can be connected to the housing by riveting.

[0027] In this embodiment, the socket housing 1 has a rectangular structure, wherein the socket lug 13 is formed on the short side of the rectangle of the socket housing 1. The second cavity 12 is a small cavity and is located near the socket lug 13 on one side. The tail of the socket 4 in the second cavity 12 is soldered and then potted, so that the volume of the second cavity 12 is a potting cavity for potting the tail of the socket 4, thereby reducing the potting cavity at the tail and saving the amount of glue used. The existing socket housing has a single layer of sockets 4, which has a total of 37. However, this application uses a small potting cavity. Considering the low cost and the fact that even with so many sockets, only a few are used, the distribution of the sockets is determined according to the actual usage. The number of sockets ranges from 2 to 36, and they can be arranged in multiple rows to reduce the potting cavity.

[0028] As a preferred option, the L-shaped locking accessory 2 is directly molded to the socket housing 1 using a mold, which improves production efficiency and avoids the quality risks associated with riveting. The original product structure involved riveting to an aluminum alloy housing, which posed a risk of damaging both the L-shaped locking accessory and the housing.

[0029] Since the existing number of sockets is large, which are spread throughout the socket housing, in this embodiment, the sockets are only set at the corresponding positions of the second cavity 12, thereby reducing the number of sockets and thus reducing the processing and electroplating costs of the sockets.

[0030] Optionally, the socket and the hole on the socket base are clearance-fitted and fixed by adhesive bonding.

[0031] In an optional embodiment, the socket base 3 is made of thermoplastic engineering plastic with a temperature resistance of -55℃ to +125℃, which facilitates mold forming and meets the environmental adaptability requirements of the product. Other materials that meet performance requirements, such as polyphenylene sulfide (PPS), are also selected. The socket 4 is machined from tin bronze (QSn4-3-Y) material with excellent machinability, as the socket size is small and requires a material with high mechanical strength. The socket surface is gold-plated. The L-shaped locking accessory 2 is made of 304 stainless steel, which has excellent corrosion resistance, requires no surface treatment, and also possesses a certain degree of toughness, providing resistance to impact and vibration.

[0032] Example 2:

[0033] An electrical connector includes a rectangular short-circuit socket as described in Example 1.

[0034] This utility model has the following beneficial effects:

[0035] (1) Simplified and integrated structure: Through structural design, the original numerous discrete parts are highly integrated and combined, minimizing the number of parts. The socket base and L-shaped locking accessories are integrally injection molded, realizing the simplification and integration of the structure.

[0036] (2) Production costs are significantly reduced; the use of engineering plastic injection molding to replace traditional aluminum alloy machining completely eliminates the cost of expensive metal raw materials and multiple post-processing steps such as milling, deburring, polishing, and electroplating. This avoids the risk of scrapping the part substrate due to substandard quality in special processes such as electroplating, and reduces quality losses.

[0037] (3) Significantly improved production efficiency and consistency; the injection molding process is highly efficient, suitable for large-scale mass production, and greatly shortens the product manufacturing cycle. The reduction in the number of parts and the integrated molding design simplify the assembly process, requiring only a few steps such as inserting holes, welding, and potting, reducing reliance on special positioning fixtures and significantly improving assembly efficiency. The injection molding process ensures high precision and consistency of part dimensions, and the simplified assembly process effectively guarantees the stability and reliability of the final product quality. The improved design simplifies the structure while ensuring reliable product performance. The potting process further enhances the stability of the internal structure and the reliability of electrical connections.

[0038] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
