Description

Technical Field

[0001] This utility model relates to the field of connector positioning clip technology, and in particular to a sealed and waterproof connector positioning clip. Background Technology

[0002] In modern electronic devices and electrical systems, connectors are key components for achieving electrical connections and signal transmission. The stability and reliability of their installation directly affect the performance of the entire system. Connector positioning clips, as auxiliary devices for fixing and positioning connectors, ensure that connectors maintain the correct position during installation and use, preventing loosening or detachment due to vibration, impact, or other factors, thereby guaranteeing the stability of electrical connections and the quality of signal transmission.

[0003] As the application scenarios of electronic devices and electrical systems continue to expand, many devices need to operate in harsh environments such as humidity, dust, and even underwater. For example, connectors in automotive electronic systems are exposed to rainwater, mud, and other erosion during vehicle operation. In this case, connectors not only need to have good electrical performance, but also reliable sealing and waterproofing capabilities to prevent moisture, dust, and other impurities from entering the connector and causing short circuits, corrosion, and other malfunctions, thus ensuring the normal operation of the equipment.

[0004] Existing connector positioning clips often focus only on localized sealing, neglecting the overall systemic design for waterproof performance. As a whole, the connection and fit between the various components of the connector positioning clip also affect its waterproof effect.

[0005] Therefore, this application develops a sealed and waterproof connector positioning clip to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a sealed and waterproof connector positioning clip to solve the problem of poor sealing effect of connectors in the prior art.

[0007] The technical solution of this utility model is: a sealed and waterproof connector positioning clip, comprising:

[0008] The positioning clamp body is used to position the wiring harness connector on the vehicle body. The positioning clamp body includes a snap-fit ​​structure and an abutment part. The positioning clamp body fixes the connector to the sheet metal through the snap-fit ​​structure. The abutment part is arranged opposite to the snap-fit ​​structure, so that the sheet metal is located between the snap-fit ​​structure and the abutment part during use and abuts against the sheet metal to block water flow.

[0009] A sealing ring is positioned at the contact point between the positioning clamp body and the sheet metal to ensure a tight fit with the sheet metal and achieve a waterproof function.

[0010] Preferably, the buckle structure has symmetrically arranged elastic limiting parts. The limiting parts can be elastically deformed by external force and move closer to each other to pass through the mounting hole of the sheet metal. After the limiting parts pass through the mounting hole, they return to their original shape, so that one side of the sheet metal abuts against the abutting part and the other side abuts against the limiting parts.

[0011] Preferably, the abutting part is an annular plate structure, and its surface facing the sheet metal is an inclined surface. The inclined surface gradually approaches the sheet metal in a radially outward direction. When the positioning clamp body is installed on the sheet metal, the edge of the inclined surface contacts the sheet metal, and the edge of the abutting part deforms, so that the abutting part is tightly abutting against the sheet metal.

[0012] Preferably, the positioning clamp body has an annular mounting groove on the side near the sheet metal, and the sealing ring is fixedly installed in the mounting groove; when the positioning clamp body is installed on the sheet metal, the sealing ring is compressed between the mounting groove and the sheet metal and deforms, thereby forming a sealing interface between the positioning clamp body and the sheet metal.

[0013] Preferably, the side of the sealing ring that contacts the sheet metal and the opposite side both form a recess, and when the sealing ring is not compressed, the thickness of the sealing ring is greater than the depth of the annular mounting groove.

[0014] Preferably, the sealing ring is made of elastic rubber, and its compression is set to ensure that the connector is positioned to meet the IPX7 and IPX9K waterproof rating requirements.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) The abutment part is an overall ring plate structure, and the surface facing the sheet metal is an inclined surface. During installation, the edge of the abutment part contacts the sheet metal first, and under the action of external force, it undergoes elastic deformation, increasing the contact area and pressure with the sheet metal, forming a tight abutment, effectively blocking water flow from directly impacting the connector, reducing the possibility of water flow entering the connector, and improving the waterproof performance in a humid environment.

[0017] (2) A sealing ring is provided between the sheet metal and the positioning clamp body. During installation, the sheet metal squeezes the sealing ring to cause it to undergo elastic deformation, tightly filling the gap between the mounting groove and the sheet metal, forming a continuous and complete sealing interface, effectively preventing moisture, dust and other impurities from entering, and improving the waterproof sealing performance.

[0023] The present invention will be further described in detail below with reference to specific embodiments:

[0024] like Figures 1-3 As shown, a sealed and waterproof connector positioning clip includes a positioning clip body 1 and a sealing ring 3. The positioning clip body 1 plays a crucial positioning role in the entire device, accurately positioning the wire harness connector at a designated position on the vehicle body. The positioning clip body 1 includes a snap-fit ​​structure 11 and an abutment portion 12. During installation, the snap-fit ​​structure 11 engages with the mounting hole 21 on the vehicle body sheet metal 2, thereby firmly fixing the wire harness connector to the sheet metal 2 and preventing the connector from loosening or shifting during use. The abutment portion 12 is arranged opposite to the snap-fit ​​structure 11. When the positioning clip body 1 is installed onto the sheet metal 2 via the snap-fit ​​structure 11, the sheet metal 2 is clamped between the snap-fit ​​structure 11 and the abutment portion 12. At this time, the abutment portion 12 is tightly pressed against the surface of the sheet metal 2. The contact area forms a physical barrier layer. When encountering water flow, the contact part 12 can effectively prevent water flow from directly impacting the connector, reducing the possibility of water flow entering the connector. Furthermore, the sealing ring 3 is installed at the contact position between the positioning clamp body 1 and the sheet metal 2. After the positioning clamp body 1 is installed on the sheet metal 2, the sealing ring 3 will undergo elastic deformation under pressure, tightly adhering to the surface of the sheet metal 2, filling the tiny gaps between the positioning clamp body 1 and the sheet metal 2, thereby forming a reliable waterproof barrier and further improving the waterproof effect of the connector.

[0025] In this embodiment, as Figure 2As shown, the abutment portion 12 has an overall annular plate structure, and its surface facing the sheet metal 2 is an inclined surface. The inclined surface gradually approaches the sheet metal 2 in a radially outward direction. When the positioning clamp body 1 is installed onto the sheet metal 2, the edge of the abutment portion 12 will first contact the sheet metal 2. Under the action of the external force applied during installation, the edge of the abutment portion 12 will undergo elastic deformation. Under pressure, the edge of the abutment portion 12 will further adhere to the sheet metal 2, thereby increasing the contact area and contact pressure between the abutment portion 12 and the sheet metal 2, thus achieving a tight abutment. This effectively prevents water from entering and greatly improves the waterproof reliability of the connector positioning clamp in humid environments.

[0026] Furthermore, the snap-fit ​​structure 11 has symmetrically distributed elastic limiting parts 111. When the limiting parts 111 are subjected to external force, they undergo elastic deformation, causing the two symmetrical limiting parts 111 to move closer to each other. In the actual installation process, when an external force in a specific direction is applied to the snap-fit ​​structure 11, the limiting parts 111 will deform and converge. At this time, the overall size of the snap-fit ​​structure 11 decreases, so that it can pass smoothly through the preset mounting hole 21 on the sheet metal 2. After the limiting parts 111 have completely passed through the mounting hole 21, the external force disappears, and the elastic limiting parts 111 recover their original deformation due to their own elasticity. After recovering their deformation, the sheet metal 2 is firmly clamped in the middle, with one side tightly abutting the abutting part 12 and the other side abutting the limiting part 111, thus realizing a reliable fixed connection between the positioning clamp body 1 and the sheet metal 2.

[0027] like Figure 3 As shown, to improve the effect of the sealing ring 3, an annular mounting groove 13 adapted to the sealing ring 3 is provided on the side of the positioning clamp body 1 near the sheet metal 2. This ensures that the sealing ring 3 can be securely fixed in the groove. When the positioning clamp body 1 is installed on the sheet metal 2, the sealing ring 3 is compressed between the mounting groove 13 and the sheet metal 2 due to the squeezing action of the sheet metal 2. During this compression process, the sealing ring 3 undergoes elastic deformation, and its original shape and size change, thereby tightly filling the gap between the mounting groove 13 and the sheet metal 2. This allows the sealing ring 3 to form a continuous and complete sealing interface between the positioning clamp body 1 and the sheet metal 2, effectively preventing moisture, dust and other impurities from entering from the connection between the positioning clamp body 1 and the sheet metal 2, and greatly improving the waterproof sealing performance of the connector positioning clamp.

[0028] Specifically, the sealing ring 3 has recesses 31 on both the side that contacts the sheet metal 2 and the opposite side. Furthermore, when the sealing ring 3 is uncompressed, its overall thickness is greater than the depth of the annular mounting groove 13. When the positioning clamp body 1 is installed on the sheet metal 2, the sealing ring 3 is compressed and deformed by the pressure from the sheet metal 2 and the mounting groove 13. At this time, the recesses 31 on both sides of the sealing ring 3 provide space for its deformation, allowing the sealing ring 3 to fill the gap between the mounting groove 13 and the sheet metal 2 more evenly and fully, effectively improving the waterproof sealing performance of the connector positioning clamp.

[0029] Furthermore, the sealing ring 3 is made of elastic rubber. By precisely controlling the compression of the sealing ring 3, it is ensured that the connector positioning clip can fully meet the IPX7 and IPX9K waterproof rating requirements.
