[0024] An electrical connector is a conductor device used to bridge two conductors in a circuit, allowing current or a signal to flow from one conductor to the other. It is widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent junction between electrical devices or wires.

[0025] After the terminals of existing electrical connectors are inserted into the housing and electrical testing is completed, terminals may fall off or pins may sink during transportation, resulting in poor quality of the electrical connectors or poor contact after connection.

[0026] This utility model proposes an electrical connector and connector assembly, which aims to prevent problems such as terminal module detachment or pin sagging.

[0027] Please see Figure 1 In one embodiment of the present invention, the electrical connector 100 includes a housing 10, a terminal module 20, and a fixing adhesive 30. The housing 10 has a through hole extending through both ends, and one end of the housing 10 is open for insertion into another connector. The terminal module 20 includes a plurality of pins 21 and a plurality of connecting wires 22, with one pin 21 and one connecting wire 22 electrically connected. The plurality of pins 21 are inserted into the other end opening of the housing 10. The fixing adhesive 30 is applied between the housing 10 and the connecting wires 22 to prevent the terminal module 20 from detaching from the housing 10.

[0028] In this embodiment, the housing 10 serves as the base structure for supporting the terminal module 20 and mating with another connector. Specifically, it can be made of injection-molded engineering plastics, such as polyamide or polycarbonate. Its through-hole design meets the requirements for pin 21 insertion and cable routing, while maintaining a compact overall connector structure. The terminal module 20 includes a combination structure of pins 21 and connecting wires 22. The pins 21 can be made of stamped copper alloy, and the connecting wires 22 can be tin-plated copper core wires. By welding individual pins 21 to corresponding connecting wires 22, a stable current transmission path is formed. The fixing adhesive 30 is a curing material used to bond the housing 10 and the connecting wires 22, specifically epoxy resin or silicone rubber. This material fills the gap between the housing 10 and the connecting wires 22 in a liquid state, and after curing, forms an elastic support layer, eliminating displacement caused by mechanical vibration.

[0029] The technical solution of this utility model uses a fixing adhesive 30 to coat between the housing 10 and the connecting wire 22 to prevent the terminal module 20 from detaching from the housing 10 under mechanical vibration or external force. This solves the problem of poor contact caused by loose terminals in traditional electrical connectors 100 and has the advantage of improving connection stability and reliability.

[0030] In the embodiments of this utility model, the fixing adhesive 30 is a UV adhesive.

[0031] In this embodiment, UV adhesive is an adhesive that cures rapidly through ultraviolet light irradiation. Specifically, it can be made from an acrylic photocurable resin, which can quickly change from a liquid to a solid state under ultraviolet light irradiation to form a strong adhesive layer. Using UV adhesive solves the problems of long curing time and low efficiency of traditional adhesives, while avoiding the risk of thermal damage to the insulation layer of the connecting wire 22 caused by high-temperature curing adhesive.

[0032] In an embodiment of this utility model, UV adhesive is applied to the opposite two edges of the opening at the other end of the housing 10.

[0033] In this embodiment, the opposite two sides of the opening at the other end of the housing 10 are two symmetrically distributed side areas of the opening on the side of the housing 10 away from the plug-in end. Specifically, this can be achieved by placing UV adhesive on the left and right sides of the end of the housing 10 after the terminal module 20 is inserted. Applying UV adhesive to this position can enhance the fixing effect on the terminal module 20.

[0034] In an embodiment of this utility model, UV adhesive is applied to the edge of the opening at the other end of the housing 10 and extends circumferentially along the opening at the other end to fix the edge of the opening at the other end of the housing 10 to a plurality of connecting lines 22.

[0035] In this embodiment, after the connecting wire 22 is inserted into the opening at the other end of the housing 10, UV adhesive is applied to the entire circumferential area along the edge of the opening at the other end of the housing 10. The adhesive wraps around the outer surface of multiple connecting wires 22 and extends to cover the interface where they contact the housing 10. Under ultraviolet irradiation, the adhesive rapidly cures to form a ring-shaped fixing structure, increasing the bonding area between the connecting wire 22 and the housing 10 and making it more uniformly distributed. This effectively restricts the displacement of the connecting wire 22 in the axial direction and improves the connection strength between the connecting wire 22 and the housing 10.

[0036] In an embodiment of this utility model, the dimension of the fixing adhesive 30 along the length direction of the connecting line 22 is greater than or equal to 5 mm and less than or equal to 10 mm.

[0037] In this embodiment, the dimension of the fixing adhesive 30 along the length direction of the connecting line 22 is greater than or equal to 5mm and less than or equal to 10mm, such as 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or any value within the above range. The size of the fixing adhesive 30 should not be too large, as this will lead to waste of adhesive. The size of the fixing adhesive 30 should also not be too small, as this will lead to an excessively narrow connection interface between the connecting line 22 and the housing 10, resulting in insufficient connection strength between the connecting line 22 and the housing 10.

[0038] In an embodiment of this utility model, the electrical connector 100 further includes a snap fastener 40, which is disposed on one side wall of the housing 10 and is used to engage with another connector.

[0039] In this embodiment, the latch 40 is a mechanical structure used to achieve a fastening connection between two connectors. Specifically, it can be implemented using a hook-shaped or clamping structure made of elastic material, generating a locking force through elastic deformation when the connectors are inserted. The latch 40 is located on the side wall of the housing 10. When the electrical connector 100 is inserted with another connector, the locking end of the latch 40 automatically engages with the corresponding connector's groove or protrusion, forming a mechanical lock. When separation is required, pressing the pressing end of the latch 40 causes it to rotate around a pivot point, disengaging the locking end from the fastening position. This structure replaces the traditional pure friction fixing method with mechanical locking, preventing the two connectors from detaching due to external impact or vibration.

[0040] In an embodiment of this utility model, the middle part of the buckle 40 is rotatably connected to the housing 10, and the other end of the buckle 40 is provided with a pressing part 41, which is driven to make one end of the buckle 40 rotate relative to the housing 10.

[0041] In this embodiment, the rotatable connection between the middle part of the buckle 40 and the housing 10 is specifically achieved by the buckle 40 forming a rotatable mechanical connection with the housing 10 through the middle part. This can be implemented using a pivot or rotating shaft structure, allowing the buckle 40 to rotate around the connection point. The pressing part 41 is a structure located at the end of the buckle 40 for applying operating force. It can be implemented using a protrusion, groove, or anti-slip texture, facilitating finger pressing and control of the buckle 40's rotation angle, thereby improving operational convenience and preventing accidental activation.

[0042] In an embodiment of this utility model, there are two buckles 40, which are respectively disposed on the two side walls of the housing 10.

[0043] In this embodiment, two latches 40 are respectively installed on the left and right side walls of the housing 10. When the electrical connector 100 is plugged into another connector, the latches 40 on both sides simultaneously engage in the corresponding slots of the mating components. The symmetrical distribution of the latches 40 ensures that the engaging force during the plugging process is evenly transmitted to both sides of the housing 10, avoiding loosening of the electrical connector 100 due to force on one side.

[0044] In the embodiments of this utility model, the buckle 40 is integrally formed with the housing 10.

[0045] In this embodiment, the buckle 40 and the housing 10 are made of the same material and are injection molded in one piece, with no seams or connecting parts between them. At predetermined positions on both side walls of the housing 10, the mold directly forms a buckle 40 structure with elastic deformation capability. The rotational connection part of the buckle 40 and the transition area of ​​the housing 10 wall thickness achieve mechanical support through material continuity. Therefore, when the buckle 40 is subjected to insertion and extraction forces, the deformation stress can be evenly transmitted to the entire structure of the housing 10 through its root connection to the housing 10, effectively preventing the risk of fracture caused by localized stress concentration.

[0046] This utility model also proposes a connector assembly, including the electrical connector 100 and the board end connector as described above, wherein the electrical connector 100 and the board end connector are plugged in and electrically connected.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
