Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to a connector assembly that is easy and quick to install. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers, typically consisting of a male connector and a female connector. Male and female connectors often employ a pluggable design, using a pluggable mechanism to quickly connect and disconnect current or signals. In practical applications, one of the male or female connectors often needs to be fixed to an external structure. Currently, one of these components is mostly fixed with screws. However, due to the frequent plugging and unplugging of male and female connectors, they are prone to damage over time. Screw fixing requires tools such as screwdrivers for installation and maintenance, making installation and maintenance time-consuming and inconvenient. Furthermore, existing male and female connector pluggable mechanisms typically involve a tongue and a slot. The tongue often extends from the connector body as an elastic rib with a barb at its front end. To disconnect, the barb is disengaged by pressing the pressing part of the tongue, allowing the connector to be pulled out. However, in existing pluggable mechanisms, the pressing surface of the tongue is lower than the upper plate of the slot and has a small pressing area, making it inconvenient for users to press, resulting in easy connection but difficult separation of the two connectors. Summary of the Invention

[0003] In view of the deficiencies of the prior art mentioned in the background section, this utility model provides a connector assembly that is convenient and quick to install.

[0004] To achieve the above-mentioned technical effects, the technical solution adopted by this utility model is as follows:

[0005] A quick-installation connector assembly includes a first connector and a second connector, both having a plug-in end and a cable lead-out end for securing and leading out a cable; the first and second connectors are locked together by plugging in their plug-in ends; characterized in that it further includes a fixing plate and a U-shaped buckle, the U-shaped buckle having a U-shaped limiting portion and a locking portion connected to both ends of the limiting portion; the limiting portion forms a limiting surface at the connection of the locking portion, and the locking portion has an anti-disengagement structure; the first connector has a recessed neck between the plug-in end and the cable lead-out end, the top surface of the neck being a distance from the first connector... The height of the lower surface is the same as the distance from the limiting surface to the bottom surface of the U-shaped groove of the U-shaped buckle; the fixing plate is attached to the lower surface of the first connector, and the fixing plate has locking holes on both sides of the neck. The U-shaped buckle is locked at the neck. According to the spacing of the locking holes on both sides of the connector, the anti-disengagement structure can pass through the locking holes after elastic deformation or relative displacement under pressure, and can limit and fix the fixing plate between the limiting surface and the anti-disengagement structure, so that the fixing plate, the U-shaped buckle and the first connector are in a relatively stable locked state. By pressing the anti-disengagement structure to make it elastically deform or relative displacement, the locked state between the three can be released, so that the U-shaped buckle can be released from the fixing plate.

[0006] The present invention is further optimized as follows:

[0007] Furthermore, the U-shaped buckle is a bent sheet structure, the distance between the two side walls of the limiting part is adapted to the distance between the two card holes, the locking part is connected to the middle of the end face of the limiting part and is formed by a partial extension of the limiting part, the width of which is adapted to the width of the card hole and is smaller than the width of the limiting part, and the locking part is provided with an arched structure protruding towards the center of the U-shaped buckle, the arched structure forming an anti-detachment structure.

[0008] Furthermore, the U-shaped buckle has a rod-shaped bent structure, the locking part has a cavity in the center, and U-shaped grooves are symmetrically provided on both sides of the locking part. The opening of the U-shaped groove faces upward and is connected to the cavity. The U-shaped groove allows the locking part to form an elastic piece inside. The lower outer surface of the elastic piece has a protrusion. The protrusion forms an anti-disengagement structure. The cross-section of the protrusion is a right-angled triangle or right-angled trapezoid with a pointed lower end.

[0009] Furthermore, the area of ​​both end faces of the limiting part is greater than the area of ​​the upper end face of the locking part, and the portion of the end face of the limiting part that extends beyond the upper end face of the locking part forms a limiting surface.

[0010] Furthermore, the limiting part includes a U-shaped rod and connecting blocks connected to both ends of the U-shaped rod. The lower end face of the connecting block is flush with the lower end face of the U-shaped rod. The locking part is connected below the end face of the U-shaped rod, and the lower end face of the connecting block forms the limiting surface.

[0011] Furthermore, the U-shaped buckle is a plastic buckle.

[0012] Furthermore, the first connector and the second connector have a limiting baffle at the cable lead-out end near the neck.

[0013] Furthermore, the first connector and the second connector have an anti-slip structure behind the limiting baffle at the cable lead-out end.

[0014] Furthermore, the first connector and the second connector are interlocked and locked together by a plugging and unplugging mechanism formed by a barbed tongue and a slot, and the rear pressing part of the tongue is provided with a protruding force-applying post.

[0015] Furthermore, the top surface of the force-applying column is a stepped surface with a lower front end and a higher rear end.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a recessed neck on the first connector, along with a U-shaped buckle for a limiting surface and an anti-detachment structure. This design facilitates easy installation and secure fixation of the first connector, eliminating the need for tools during disassembly and enabling convenient and efficient maintenance and replacement. Limiting baffles and anti-detachment structures at the cable exit ends of both the first and second connectors are incorporated. The limiting baffles restrict the front end of the heat-shrink tubing fitted onto the cable exit ends of the first and second connectors, while the anti-detachment structure increases the release force after heat shrinking, effectively protecting the connection strength between the wire and the cable exit end and enhancing the connector's waterproof capability. A protruding force-applying post at the rear pressing part of the tongue optimizes the pressing structure, making separation of the first and second connectors convenient.

[0039] Example

[0040] A connector assembly that can be quickly installed, such as Figure 1-5As shown, the connector assembly includes a first connector 1, a second connector 2, a fixing plate 3, and a U-shaped buckle 4. One of the first connectors 1 and the second connector 2 is a male connector, and the other is a female connector. Both connectors have a plug-in end 11 for mutual insertion and locking, and a cable lead-out end 12 for fixing the connection and leading out the cable. The plug-in ends 11 are mutually inserted and locked together by a plug-in mechanism 6 formed by a tongue 62 with barbs 63 and a slot 61. The U-shaped buckle 4 has a U-shaped limiting part 41 and locking parts 42 connected to both ends of the limiting part 41. The limiting part 41 forms limiting surfaces 41a and 41b at the connection of the locking parts 42 (e.g., ...). Figure 6 , 8 As shown), the locking part 42 is provided with an anti-disengagement structure 421. The first connector 1 has a recessed neck 13 between the plug-in end 11 and the cable lead-out end 12. The height of the upper surface of the neck 13 from the lower surface of the first connector 1 is the same as the distance from the limiting surfaces 41a and 41b to the bottom surface of the U-shaped groove of the U-shaped buckle 4. The recess can be located on both sides of the neck 13 alone, or it can be located on the top of the neck 13 alone (that is, the surfaces on both sides of the neck are recessed from the surfaces on both sides of the plug-in end 11 and the cable lead-out end 12, or the upper surface of the neck is lower than the upper surfaces of the plug-in end 11 and the cable lead-out end 1 at both ends of the neck). The fixing plate 3 is attached to the lower surface of the first connector 1. The fixing plate 3 has a locking hole 31 on both sides of the neck 13, and the U-shaped buckle 4 is locked at the neck 13. Based on the spacing of the locking holes 13 on both sides of the first connector 1, the anti-detachment structure 421, after being pressed and undergoing elastic deformation or relative displacement, passes through the locking holes 13 and can limit and fix the fixing plate 3 between the limiting surfaces 41a, 41b and the anti-detachment structure 421, so that the fixing plate 3, the U-shaped buckle 4 and the first connector 1 are in a relatively stable locked state. By pressing the anti-detachment structure 421 to cause elastic deformation or relative displacement, the locking state between the three can be released, so that the U-shaped buckle 4 can be detached from the fixing plate 3.

[0041] This invention features a recessed neck on the first connector, along with a U-shaped latch providing a limiting surface and an anti-detachment structure. This design facilitates easy installation and secure fixation of the first connector, eliminating the need for tools during disassembly and enabling convenient and efficient maintenance and replacement. It's important to note that the term "recessed neck" in this embodiment can be understood as the outer surface of the neck being recessed compared to the outer surfaces of the connection points between the plug-in ends and the cable leads on either side. Alternatively, it can be understood as both the plug-in ends and the cable leads having baffles at their connection points with the neck, or a baffle on one side and a recessed design on the other side, making the neck surface lower than the surfaces at their connection points. In short, the recessed design ensures the neck can engage with the U-shaped latch, preventing lateral movement after the latch is engaged. The fixing plate in this embodiment can be a separate panel or part of the outer shell of an object.

[0042] As a preferred option, such as Figure 1 , 4 As shown in Figures 6 and 7, in this embodiment, the U-shaped buckle 4 is a metal buckle formed by stamping and bending a metal sheet. The distance between the two side walls of the limiting part 41 of the U-shaped buckle 4 is adapted to the distance between the two locking holes 31 of the fixing plate 3 and the distance between the two sides of the neck 13. The locking part 42 is connected to the middle of the end face of the limiting part 41 and is formed as a partial extension (middle extension) of the limiting part 41. The width of the locking part 42 is adapted to the width of the locking hole 31. The part of the lower surface of the limiting part 41 that extends beyond the locking part 42 is formed as a limiting surface 41a that abuts against the fixing plate 3. The locking part 42 is provided with an arched structure protruding towards the center of the U-shaped buckle 4. This arched structure is formed as an anti-detachment structure 421.

[0043] As a preferred option, such as Figure 5 , 8 As shown in Figure -10, the U-shaped buckle 4 is an injection-molded plastic buckle with a rod-shaped bent structure. The inner surface of the buckle that fits against the neck 13 is the same as the surface of the neck 13. The locking part 42 of the U-shaped buckle 4 has a cavity in the center. The surfaces on both sides of the locking part 42 have U-shaped grooves 422 that communicate with the internal cavity and face upward. An elastic piece 423 is formed in the U-shaped groove 422 of the locking part 42. The outer surface of the elastic piece 423 has a protrusion 424 with a right-angled triangle or right-angled trapezoidal shape with a pointed lower end. The protrusion 424 on the elastic piece 423 constitutes an anti-detachment structure 421. In this embodiment, the end face area of ​​the two limiting parts 41 is larger than the end face area of ​​the locking part 42 connected to them. The part of the end face of the limiting part 41 that extends beyond the upper end face of the locking part 42 is formed as a limiting surface 42b that abuts against the fixing plate 3. More preferably, the limiting part 41 includes a U-shaped rod 411 and connecting blocks 412 connected to both ends of the U-shaped rod 411. The lower end face of the connecting block 412 is flush with the lower end face of the U-shaped rod 411. The locking part 42 is connected to the lower end of the end face of the U-shaped rod 411, and the end face areas of the two connecting ends can be the same. The lower end face of the connecting block 412 is configured as a limiting surface 42b that abuts against the fixing plate 3 or is a part of the limiting surface 42b. Example

[0044] like Figure 1-3As shown, the first connector 1 and the second connector 2 are provided with limiting baffles 15 near the neck 13 at the cable lead-out end 12. Behind the limiting baffles 15 at the cable lead-out end 12, the first connector 1 and the second connector 2 are provided with anti-slip structures 14. The anti-slip structure 14 is a triangular or trapezoidal cross-section protrusion with a larger front and smaller rear, arranged continuously or intermittently on the connector surface. Of course, the anti-slip structure 14 can also be other types, such as anti-slip protrusions or anti-slip grooves. In the actual production process of this connector, a heat shrink tube 5 is fitted onto the cable lead-out portion of the rear cable lead-out end 12 of the connector. The front end of the heat shrink tube 5 is restrained by the limiting baffles 15, and a certain length is left at the rear end to wrap the lead-out cable, thereby enhancing the strength of the connector at the cable lead-out portion and the waterproof function of the connection. The anti-detachment structure 14 can increase the detachment force of the heat shrink tube 5 after heat drying. More preferably, in this embodiment, the limiting baffles 15 used to limit the heat shrink tube 5 can be used as a baffle at the neck 13 near the cable lead-out end 12. Example

[0045] like Figure 2 , 3 As shown, to facilitate easier separation of the two connectors, a protruding force-applying post 64 is provided at the rear pressing part of the tongue 62. The force-applying post 64 can be a solid or hollow cylindrical structure located at the rear pressing part of the tongue 62, or it can be a bridge-shaped structure supported on both sides of the tongue 62 by support ribs, with the support ribs connected above each other. More preferably, the top surface of the force-applying post 64 is a stepped surface with a higher front end and a higher rear end.

[0046] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
