Limiting mechanisms are provided on both sides of the plug portion, each limiting mechanism including a locking rod. The locking rod is fixedly connected to the plug portion via a fixing block. The slot portion has a slot, with a retaining groove formed at the end of the slot.

Description

Technical Field

[0001] This utility model relates to the field of quick-connect wire harness connectors, specifically a quick-connect electronic connector. Background Technology

[0002] Quick-connect harnesses are high-efficiency electrical connection components widely used in automobiles, industrial equipment, and electronic products. They enable quick plugging and unplugging of multiple wires or optical fibers. Their core features are easy operation and reliable connection. They mainly consist of a plug and a socket and have protective properties such as waterproof, dustproof, and vibration resistance. According to their uses, they can be divided into power, signal, and hybrid types; according to their structure, they can be straight-plug, snap-fit, and push-pull types.

[0003] Current electronic wire harness quick connectors achieve electrical connection through the insertion and mating of plugs and slots. However, there is a problem in their actual use: the traditional plug and slot installation relies solely on a single locking structure for limiting the position and improving the stability of the connection. This single locking structure is prone to instability. Therefore, the inventors urgently need to design a quick-locking mechanism to improve the connection stability of wire harness connectors. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a quick-connect electronic connector to solve the technical problem that traditional connectors mainly rely on a single fastening structure to limit and fix the plug and slot. In usage scenarios with frequent vibration or many insertion and removal times, this setting often exhibits insufficient stability and easy loosening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect electronic connector, including a plug portion and a slot portion. Both sides of the plug portion are provided with limiting mechanisms. The limiting mechanism includes a locking rod. The locking rod is fixedly connected to the plug portion through a fixing block. The slot portion has a slot. The end of the slot forms a slot, and the beginning of the slot forms a groove. The slot is a sliding groove for the locking rod to access and engage with the opening of the slot.

[0006] By adopting the above technical solution, the insertion positioning accuracy is significantly improved through the combined effect of the limiting mechanism set on both sides of the plug and the slotted structure on the slot. The locking rod in the limiting mechanism is rigidly connected to the plug through the fixing block to ensure the reliability of force transmission. When the locking rod enters the slide through the slot, the flared structure at the beginning of the slot provides ample initial guiding space, reducing the difficulty of alignment.

[0007] Furthermore, the slide groove has an oblique structure, the locking rod has a "C" shaped structure, the locking rod moves inside the slide groove, and the oblique structure of the slide groove allows the locking rod to be inserted into the slot for charging.

[0008] By adopting the above technical solution, its inclined path forces the "C"-shaped locking rod to undergo controllable elastic deformation during the sliding process, converting the external insertion force into the deformation potential energy of the locking rod. This energy conversion mechanism buffers the insertion impact on the one hand, avoiding hard collision damage to the terminal; on the other hand, it stores mechanical energy for final locking.

[0009] Furthermore, the plug portion includes several sub-modules, and adjacent sub-modules are connected in a detachable structure with sliding blocks.

[0010] By adopting the above technical solution, mechanical coupling between sub-modules is achieved through the sliding groove and slider structure, making the connector highly scalable. Users can freely combine the number of modules according to the actual number of cables, avoiding the situation where the entire connector is scrapped due to single-point damage in traditional integrated plugs.

[0011] Furthermore, a snap-fit ​​mechanism is provided above the plug portion and the slot portion. The snap-fit ​​mechanism includes a fixing piece and a snap-fit ​​block. The fixing piece is fixed above the plug portion, and the snap-fit ​​block is fixed above the slot portion.

[0012] A pressing piece is elastically connected above the fixing piece. The pressing piece has a raised structure. A lever is fixedly connected to one side of the pressing piece. A locking connector is provided at the end of the lever. The locking connector engages with the locking block.

[0013] The snap-fit ​​block has a wedge-shaped structure, and one side of the snap-fit ​​connector has an inclined surface, which serves as a guide surface for the snap-fit ​​connector to snap onto the snap-fit ​​block.

[0014] By adopting the above technical solution, the top snap-fit ​​mechanism constitutes a second locking defense: the rigid fixation of the fixing piece and the plug part, and the integrated design of the snap-fit ​​block and the slot part form a locking anchor point across the structure. On this basis, the elastically connected pressing piece provides tactile feedback through the tilting structure: when the snap-fit ​​connector contacts the wedge-shaped snap-fit ​​block, the inclined guide structure makes the two automatically align and slide together.

[0015] Furthermore, the plug portion and the slot portion are connected to the slot via a connector and are electrically connected.

[0016] By adopting the above technical solution, the direct plug-in connection between the connector and the slot constitutes the core path of electrical connection, while the aforementioned mechanical locking mechanism provides multi-dimensional protection for the electrical contact. The limiting mechanism resists lateral displacement and prevents the connector from experiencing fretting wear in the slot.

[0017] In summary, the present invention has the following main advantages: This invention utilizes a limiting mechanism to generate elastic energy as the locking rod slides along the inclined groove of the slot. Upon entering the end slot, it releases potential energy to form a continuous holding force, effectively resisting lateral vibration and insertion / extraction stress. Simultaneously, the design guides the "C"-shaped locking rod to adaptively deform through the inclined surface of the groove, preventing damage to the terminals from hard impacts. Furthermore, the insertion process can achieve mechanical self-locking without additional operation, thereby further improving the connection stability of the connector. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] Example 1: A quick-connect electronic connector, such as Figure 1-4As shown, the device includes a plug portion 1 and a slot portion 2. Limiting mechanisms 3 are provided on both sides of the plug portion 1. Each limiting mechanism 3 includes a locking rod 301, which is fixedly connected to the plug portion 1 via a fixing block 302. A slot 305 is formed on the slot portion 2. A slot 304 is formed at the end of the slot 305, and a slot 305 is formed at the beginning of the slot 305. The slot 305 allows the locking rod 301 to access the sliding groove 303 and engage with the opening of the slot 304. The limiting mechanisms 3 on both sides of the plug portion 1 work in conjunction with the specially structured slot 305 on the slot portion 2. The function is to significantly improve the positioning accuracy of the plug. The locking rod 301 in the limiting mechanism 3 is rigidly connected to the plug part 1 through the fixing block 302 to ensure the reliability of force transmission. When the locking rod 301 enters the slide groove 303 through the slot 305, the flared structure at the beginning of the slot 305 provides ample initial guiding space and reduces the difficulty of alignment. At the same time, the locking groove 304 formed at the end of the slot 305 creates a precise locking position. When the locking rod 301 is finally locked into the locking groove 304, the interference fit of the mechanical structure produces a self-locking effect, which effectively resists lateral vibration and axial tension.

[0022] See Figure 1 , Figure 2 The slide groove 303 has an oblique structure, and the locking rod 301 has a "C"-shaped structure. The locking rod 301 moves inside the slide groove 303. The oblique structure of the slide groove 303 allows the locking rod 301 to be inserted into the locking slot 304 for energy charging. Its oblique path forces the "C"-shaped locking rod 301 to undergo controllable elastic deformation during sliding, converting the external insertion force into the deformation potential energy of the locking rod 301. This energy conversion mechanism buffers the insertion impact and avoids damage to the terminals from hard collisions. On the other hand, it stores mechanical energy for final locking. At the same time, the open ring feature of the C-shaped structure gives the locking rod 301 a dual degree of freedom of elasticity: radial elasticity allows it to adaptively adjust its position within the slide groove 303, while circumferential elasticity enhances its ability to resist torsional loads. When the locking rod 301 slides into the locking slot 304, the accumulated elastic potential energy is released instantaneously, forming a continuous contact pressure to ensure that the locking state is not maintained by external force.

[0023] See Figure 1 , Figure 3 The plug part 1 includes several sub-modules. Adjacent sub-modules are connected by a detachable sliding block structure. The mechanical coupling between sub-modules is achieved through the sliding block structure, which makes the connector highly scalable. Users can freely combine the number of modules according to the actual number of cables, avoiding the situation where the entire plug is scrapped due to a single point of failure in traditional integral plugs. At the same time, the detachable connection method of the sliding block creates a dual advantage: on the manufacturing side, it simplifies the mold complexity and reduces the difficulty of precision injection molding; on the maintenance side, it can be repaired by simply replacing the faulty sub-module, which greatly reduces the operation and maintenance costs.

[0024] Example 2: See Figure 3 , Figure 4 A snap-fit ​​mechanism 4 is provided above the plug part 1 and the slot part 2. The snap-fit ​​mechanism 4 includes a fixing piece 401 and a snap-fit ​​block 404. The fixing piece 401 is fixed above the plug part 1, and the snap-fit ​​block 404 is fixed above the slot part 2.

[0025] A pressing piece 405 is elastically connected above the fixing piece 401. The pressing piece 405 has a raised structure. A paddle 402 is fixedly connected to one side of the pressing piece 405. A locking connector 403 is provided at the end of the paddle 402. The locking connector 403 is locked with the locking block 404.

[0026] The snap-fit ​​block 404 has a wedge-shaped structure, and one side of the snap-fit ​​connector 403 has a beveled structure, which serves as a guide surface for the snap-fit ​​connector 403 to snap into the snap-fit ​​block 404. The top snap-fit ​​mechanism 4 constitutes a second locking defense: the rigid fixing of the fixing piece 401 and the plug part 1, and the integrated design of the snap-fit ​​block 404 and the slot part 2 form a locking anchor point across the structure. On this basis, the elastically connected pressing piece 405 provides tactile feedback through the raised structure: when the snap-fit ​​connector 403 contacts the wedge-shaped snap-fit ​​block 404, the beveled guide structure makes the two automatically align and slide together. At the same time, the pressing piece 405 stores elastic potential energy during the pressing process. When the snap-fit ​​connector 403 is fully snapped into one side of the snap-fit ​​block 404, the pressing piece 405 rebounds and drives the snap-fit ​​connector 403 to generate a vertically downward locking force. This force is coupled with the normal component force of the wedge-shaped surface to form a three-dimensional constraint.

[0027] See Figure 1 , Figure 2 , Figure 3 The plug part 1 and the slot part 2 are connected to the slot 502 through the plug 501 and are electrically connected. The direct plug-in connection between the plug 501 and the slot 502 constitutes the core path of electrical connection. The aforementioned mechanical locking mechanism provides multi-dimensional protection for this electrical contact. The limiting mechanism 3 resists lateral displacement and prevents the plug 501 from fretting wear in the slot 502. The snap-fit ​​mechanism 4 at the top eliminates axial gaps by continuous pressing and maintains stable contact positive pressure.

[0028] The implementation principle of this embodiment is as follows: the plug 501 of the plug part 1 is aligned with the slot 502 of the slot part 2 and inserted. At this time, the limiting mechanism 3 on both sides of the plug part 1 starts to work. The locking rod 301 is fixed on the plug part 1 and enters the inclined slide groove 303 along the slot 305 of the slot part 2. Due to the inclined setting of the slide groove 303, the locking rod 301 is guided by the inclined surface and elastically deformed during the sliding process, accumulating potential energy.

[0029] When the insertion depth reaches the preset position, the locking rod 301 slides into the locking groove 304 at the end of the slide groove 303, completing the first locking. At this time, the locking rod 301 releases elastic potential energy to form a continuous holding force.

[0030] Subsequently, the locking mechanism 4 located above the plug part 1 and the slot part 2 simultaneously performs a locking operation. The locking block 404 fixed on the slot part 2 interacts with the locking connector 403 above the fixing piece 401 of the plug part 1. When the locking connector 403 contacts the wedge-shaped locking block 404, its inclined structure guides the locking connector 403 to automatically slide under the locking block 404. At the same time, the paddle 402 connected to the locking connector 403 pushes the pressing piece 405 to press down temporarily. After the locking connector 403 is fully engaged, the pressing piece 405 rebounds.

[0031] Finally, the oblique locking of the two side limiting mechanisms 3 and the elastic pressing of the upper locking mechanism 4 achieve double mechanical locking, ensuring a stable electrical connection between the plug part 1 and the slot part 2. When unlocking, simply press down the pressing piece 405 to disengage the locking connector 403 from the locking block 404, and at the same time, pry the locking rod 301 to disengage the locking rod 301 from the slot 304, so that the plug part 1 can be pulled out.
