Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a quick-assembly plug-in and connector. Background Technology

[0002] Connectors, as fundamental components for electrical and signal connections, are widely used in consumer electronics, communication equipment, computers and peripherals, automotive electronics, industrial automation, and other industries. In these scenarios, connectors are commonly used for board-to-wire, wire-to-wire, module mating, charging and data expansion interfaces, requiring frequent mating and unmating during assembly, maintenance, upgrades, or field repairs. Many applications also require connectors to maintain long-term reliable mechanical locking and electrical contact under harsh environments such as vibration, shock, temperature cycling, and humidity, while also facilitating quick replacement and maintenance to minimize downtime and reduce maintenance costs.

[0003] Existing connectors generally employ built-in latches or claws (i.e., integrated injection-molded fasteners) with male and female connectors molded on the housing to achieve mechanical locking after insertion, or use different locking methods such as metal springs, threads, and quick-release rings. From the perspective of "locking component durability," integrated injection-molded plastic latches are prone to plastic fatigue, creep, or breakage under repeated insertion and removal or long-term vibration and environmental aging, leading to latch failure, reduced locking force, or even accidental connector disengagement. More importantly, such failures are usually accompanied by wear or damage to the connector body (housing or contact springs), requiring the replacement of the entire connector assembly during maintenance, increasing costs and downtime. The main technical problem arising from this is that traditional integrated injection-molded latches are prone to failure after repeated insertion and removal and may damage the connector body, lacking a structural solution that can both guarantee reliable locking and facilitate replacement and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly plug-in and connector to solve the above-mentioned technical problems.

[0005] To achieve this objective, the present invention adopts the following technical solution: A quick-assembly plug-in includes a plug-in body, a plug-in hole through the plug-in body, and sliding grooves on both sides of the plug-in body. The sliding grooves extend in a direction perpendicular to the plug-in hole, and a positioning block is slidably connected in the sliding groove. The first end of the positioning block is provided with an elastic element, and one end of the elastic element is connected to the plug-in body. The second end of the positioning block is provided with a wedge-shaped surface and a stop surface. The wedge-shaped surface extends gradually from the outside to the inside of the insertion hole towards the central axis of the insertion hole.

[0006] Optionally, the main body of the plug-in is slidably connected with an unlocking component, the unlocking component is provided with a connecting component, and the two ends of the connecting component are respectively connected to the corresponding positioning blocks; Move the unlocking component so that the two positioning blocks move away from the central axis of the insertion hole via the connector.

[0007] Optionally, the plug body has a mounting groove in the middle, and the unlocking component is slidably connected to the mounting groove in a direction perpendicular to the plug hole; The connector is a connecting rope, and the unlocking component has a push-up protrusion in the middle. One end of the push-up protrusion abuts against the connecting rope. Pressing the unlocking component will push the connecting ropes on both sides to converge towards the middle.

[0008] Optionally, a connecting post is provided at a preset position in the chute, the connecting post is equipped with a top wheel, and the top wheel has a limiting groove for the connecting rope to pass through; The connecting post is positioned further away from the central axis of the insertion hole than the positioning block and the pushing protrusion.

[0009] Optionally, the unlocking component includes a sliding body and a pressing part, the sliding body being slidably connected to the mounting groove, and the pressing part being provided with a pressing slope.

[0010] Optionally, the quick-assembly plug-in further includes an elastic block, the first end of which is provided with the elastic element, and the second end of which is provided with an abutment portion; The abutting part includes two symmetrically arranged inclined surfaces, which are used to push the elastic block to move away from the central axis of the insertion hole during insertion.

[0011] Optionally, each of the two ends of the insertion hole is provided with a guide portion, which is an arc-shaped curved surface that is gradually recessed from the outside to the inside.

[0013] Optionally, the connector further includes a male connector assembly and a female connector assembly that are plugged into each other, and the male connector assembly and the female connector assembly are respectively provided with a groove portion; when plugged in, the positioning block is engaged with the groove portion.

[0014] Compared with the prior art, this utility model has the following beneficial effects: This quick-assembly plug is applied to connectors, mainly for connecting male and female plugs. During installation, the male and female plugs are aligned with the two ends of the insertion hole and inserted. When either plug is inserted into the first position, its insertion section first contacts the wedge-shaped surface of the positioning block. As the plug continues to be pushed in, the wedge-shaped surface gradually approaches the central axis along the insertion hole from the outside to the inside. With the help of the wedge surface, the positioning block is pushed along the slide groove to make room for insertion. After the plug continues to be pushed into the second position, the elastic restoring force of the first end of the positioning block causes the positioning block to return to its original position. The wedge-shaped end or stop surface of its second end falls into the corresponding groove of the plug. The stop surface prevents the plug from sliding out in the opposite direction, thus locking it. When disassembly or replacement is required, the plug can be pulled out by releasing the positioning block, thereby achieving quick disassembly and convenient replacement of the plug, protecting and extending the service life of the connector body.

[0019] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: Combination Figures 1 to 3 As shown, this utility model embodiment provides a quick-assembly plug-in, including a plug-in body 1, a plug-in hole 2 through the plug-in body 1, and sliding grooves 3 on both sides of the plug-in body 1, the sliding grooves 3 extending in a direction perpendicular to the plug-in hole 2, and a positioning block 4 slidably connected in the sliding grooves 3.

[0023] It should be noted that a pair of parallel grooves 3 are respectively opened on both sides of the plug body 1 along the direction perpendicular to the axis of the insertion hole 2. The grooves 3 are straight guide channels opened along the thickness direction, and their inner sidewalls match the shape of the positioning block 4 to restrict the translational freedom of the positioning block 4 within the grooves 3. The positioning blocks 4 are installed in their respective grooves 3 by sliding fit. The positioning blocks 4 can be integral plastic parts or made of metal / plastic composite parts. An appropriate fit clearance is maintained between them and the grooves 3 to ensure smooth sliding without obvious lateral wobbling.

[0024] For ease of assembly, the positioning block 4 can be inserted laterally or from the opening end of the plug body 1, and then fixed within the axial range of the groove 3 by a limiting structure (such as a locking step or screw). This structure allows the positioning block 4 to be pushed or reset in a direction perpendicular to the insertion hole 2, thereby achieving the locking function of the plug position.

[0025] Combination Figure 2 and 3 As shown, the first end of the positioning block 4 is provided with an elastic element 5, one end of which is connected to the plug body 1; the second end of the positioning block 4 is provided with a wedge-shaped surface 6 and a stop surface 7, the wedge-shaped surface 6 is provided to gradually extend from the outside to the inside of the plug hole 2 towards the central axis of the plug hole 2.

[0026] It should be noted that the elastic element 5 can be in the form of an integrally formed elastic tongue, an independent spring element or an elastic washer, etc. One end of it is fixed or riveted to the plug body 1, and the other end is fixed to the first end of the positioning block 4 to provide a reset force. The stiffness of the elastic element 5 should be selected according to the insertion and extraction force requirements so that the positioning block 4 can be pushed open when the plug is pushed in, and the positioning block 4 can be reliably pushed back after the plug is in place.

[0027] When the plug enters the insertion hole 2 and contacts the wedge-shaped surface 6, the plug continues to advance, generating a force component along the wedge surface that moves the positioning block 4 outward, causing the positioning block 4 to move away from the insertion position to allow the plug to pass through. When the plug is advanced to the designated position and aligned with the positioning groove of the plug body 1, the rebound force of the elastic element 5 causes the positioning block 4 to reset, and its stop surface 7 falls into the corresponding groove or positioning slot of the plug, thereby bearing the axial pull-out force through the stop surface 7 and preventing the plug from sliding out in the opposite direction. This wedge-stop-elastic element 5 combination achieves the coordinated operation of insertion force guidance, automatic reset, and reliable locking.

[0028] The working principle of this invention is as follows: This quick-assembly plug is applied to connectors, mainly for connecting male and female plugs. During installation, the male and female plugs are aligned with the two ends of the insertion hole 2 and inserted. When either plug is inserted into the first position, its insertion section first contacts the wedge-shaped surface 6 of the positioning block 4. As the plug continues to advance, the wedge-shaped surface 6 gradually approaches the central axis from the outside to the inside along the insertion hole 2. With the help of the wedge surface, the positioning block 4 is pushed along the slide groove 3 to make room for insertion. After the plug continues to advance to the second position, the elastic element 5 at the first end of the positioning block 4 restores the positioning block 4 to its original position. The wedge-shaped end or stop surface 7 at the second end falls into the corresponding groove 23 of the plug. The stop surface 7 prevents the plug from sliding out in the opposite direction, thus locking it. When disassembly or replacement is required, the plug can be pulled out by releasing the positioning block 4, thereby achieving quick disassembly and convenient replacement of the plug, protecting and extending the service life of the connector body.

[0029] In this embodiment, it is further explained that the plug body 1 is slidably connected with an unlocking component 8, the unlocking component 8 is provided with a connector, and the two ends of the connector are respectively connected to the corresponding positioning blocks 4; moving the unlocking component 8 can drive the two positioning blocks 4 to move away from the central axis of the plug hole 2 through the connector.

[0030] It should be noted that when the unlocking component 8 slides along the direction perpendicular to the plug hole 2, the connecting component simultaneously drives the left and right positioning blocks 4 to translate away from the central axis of the plug hole 2, thereby disengaging the positioning blocks 4 from the groove or stop position corresponding to the plug, releasing the lock, and enabling the plug to be released or easily disassembled.

[0031] In this embodiment, it is specifically described that, in conjunction with Figure 3 As shown, the main body 1 of the plug has an installation groove 10 in the middle, and the unlocking part 8 is slidably connected to the installation groove 10 in a direction perpendicular to the plug hole 2; the connecting part is a connecting rope 9, and the unlocking part 8 has a push protrusion 11 in the middle. One end of the push protrusion 11 abuts against the connecting rope 9. Pressing the unlocking part 8 will push the connecting ropes 9 on both sides to converge towards the middle.

[0032] In a more specific implementation, the main body 1 of the plug has an installation groove 10 in the middle, the unlocking part 8 is slidably arranged along the installation groove 10, the connecting part is a connecting rope 9 of fixed length, and its two ends are fixedly connected to the left and right positioning blocks 4 or fixed by the limiting part; the unlocking part 8 has a downward pushing protrusion 11 in the middle, and one end of the pushing protrusion 11 abuts against the middle of the connecting rope 9.

[0033] When the unlocking element 8 is pressed, the pushing protrusion 11 presses downwards against the middle of the connecting rope 9, causing the middle of the connecting rope 9 to shift downwards and resulting in a corresponding shortening of the effective length on both sides of the rope. This pulls the positioning blocks 4 on both sides simultaneously towards the outside of the slide groove 3, realizing the reverse movement and unlocking of the positioning blocks 4. After releasing the unlocking element 8, the positioning blocks 4 return to their original position under the restoring force of the elastic element 5 at their first end, and the connecting rope 9 returns to its initial tension state.

[0034] As a preferred embodiment, a connecting post 12 is provided at a preset position in the slide 3, and a top wheel 13 is installed on the connecting post 12. The top wheel 13 has a limiting groove for the connecting rope 9 to pass through. The connecting post 12 is located further away from the central axis of the insertion hole 2 than the positioning block 4 and the pushing protrusion 11.

[0035] To reduce friction and wear on the connecting rope 9 during repeated unlocking and to ensure stable force direction, this embodiment provides a connecting post 12 at a preset position in the slide groove 3. A rotatable top wheel 13 is mounted on the connecting post 12, and the top wheel 13 has a limiting groove or channel for the connecting rope 9 to pass through and be positioned. The connecting post 12 and the top wheel 13 are positioned further away from the central axis of the insertion hole 2 relative to the positioning block 4 and the pushing protrusion 11, causing the connecting rope 9 to bend or be guided at the top wheel 13, thereby efficiently converting longitudinal displacement into outward tension under the action of the pushing protrusion 11.

[0036] In this embodiment, the unlocking component 8 includes a sliding main body 14 and a pressing part 15. The sliding main body 14 is slidably connected to the mounting groove 10, and the pressing part 15 is provided with a pressing slope 16.

[0037] It should be noted that the pressing part 15 is located on one side of the exposed part of the sliding main body 14. The pressing part 15 is provided with a pressing slope 16 so that when the operator or tool applies force, it can be smoothly converted into sliding displacement along the direction of the mounting groove 10. The slope and outer surface of the pressing slope 16 can be treated with anti-slip texture or groove to improve the feel and convenience. When pressure is applied to the pressing part 15, the sliding main body 14 slides linearly in the mounting groove 10, thereby driving the positioning block 4 or other linkage components to complete the unlocking action through the connected transmission or traction mechanism (such as the connecting rope 9, connecting rod, etc.). After releasing the press, the sliding main body 14 can return to the initial position under the action of the elastic return member (such as the return spring or the elastic member 5 of the positioning block 4).

[0038] In this embodiment, the quick-assembly plug-in also includes an elastic block 17. The first end of the elastic block 17 is provided with an elastic element 5, and the second end of the elastic block 17 is provided with an abutment portion 18. The abutment portion 18 includes two symmetrically arranged inclined surfaces 19. The inclined surfaces 19 are used to push the elastic block 17 to move away from the central axis of the insertion hole 2 during insertion.

[0039] During plug insertion, the plug contacts the inclined surface 19 and pushes the spring block 17 symmetrically away from the central axis of the insertion hole 2. This provides additional lateral support and cushioning before the positioning block 4 is fully reset or during insertion / removal, preventing the plug from becoming misaligned and stuck. When the plug is in place or removed, the elastic element 5 returns the spring block 17 to its original position, restoring the central support state. This combination of spring block 17 and elastic element 5 improves the insertion / removal feel, reduces local stress concentration, and prevents plug misalignment and jamming. It also works in conjunction with the positioning block 4 to provide more stable locking and guiding performance.

[0040] As an optional solution in this embodiment, guide portions 20 are provided at both ends of the insertion hole 2. The guide portions 20 are arc-shaped curved surfaces that are gradually recessed from the outside to the inside.

[0041] The two ends of the insertion hole 2 can be respectively set as arc-shaped guide surfaces that gradually concave from the outside to the inside (i.e., arc or elliptical arc surfaces that gradually narrow from the outer end to the inner end). When the plug approaches, the arc surface can guide the plug to the center of the hole, reduce the impact and friction between the plug and the wedge surface 6 or the positioning structure, reduce the misinsertion angle, and protect the contact and locking parts from local impact damage.

[0042] Example 2: Combination Figure 4 and Figure 5 As shown, the present invention also provides a connector, including a quick-assembly plug as described in the embodiment, and further including a male connector assembly 21 and a female connector assembly 22 that are plugged into each other, wherein the male connector assembly 21 and the female connector assembly 22 are respectively provided with a groove portion 23; during insertion, the positioning block 4 is engaged with the groove portion 23.

[0043] The working principle of this connector is as follows: The male connector assembly 21 and the female connector assembly 22 are aligned and pushed in along the axis of the insertion hole 2. When the plug enters the first position, it contacts the wedge-shaped surface 6 of the positioning block 4. As it continues to advance, the wedge-shaped surface 6 pushes the positioning block 4 open along the slide groove 3 to create a passage. When the plug is pushed to the second position and aligned with the groove 23 on the plug or insert, the positioning block 4 resets under the rebound force of the elastic element 5. Its stop surface 7 embeds into the corresponding groove 23 of the plug, bearing the axial pull-out force and preventing reverse slippage. If disassembly is required, pressing or pushing the unlocking element 8 (such as the pusher protrusion 11 driving the connecting rope 9 or other linkage mechanisms) causes the left and right positioning blocks 4 to move outward synchronously, disengaging from the groove, allowing the plug to be pulled out.

[0044] The connector achieves reliable automatic locking and synchronous unlocking through an external resettable positioning block 4 and an elastic / unlocking mechanism, which not only improves vibration resistance and anti-disengagement performance, but also facilitates the quick replacement of worn parts, thereby protecting the connector body and extending its service life.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
