Description

Technical Field

[0001] This application relates to the field of wiring connectors, and more particularly to a waterproof wiring harness connector. Background Technology

[0002] Connectors, also known as plugs or sockets in China, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. Connections between wire harnesses and between wire harnesses and electrical components generally use connectors. Wire harness connectors are used in automobiles, home appliances, instruments, office equipment, commercial machines, information industry component leads, electronic control boards, digital products, and the automotive industry. With the increasing functionality of automobiles and the widespread application of electronic control technology, there are more and more electrical components, and the demand for wiring connectors has increased significantly.

[0003] The existing Chinese utility model patent with publication number CN215418746U discloses a water-proof connector with strong sealing performance; however, it still has the following shortcomings in practical use:

[0004] In the comparative document, two waterproof composite frames are fitted onto the connector after wiring. Then, the two waterproof composite frames are fixed together by connecting bolts to ensure the sealing of the connector. This operation makes the installation and disassembly process cumbersome, and the connection is not tight because it is only connected by bolts on one side. In addition, after long-term use, it is not possible to visually check whether the connector has fallen off. Utility Model Content

[0005] To improve the cumbersome process of ensuring the sealing of connectors by means of connecting bolts, and to address the problem of not being able to visually check whether the connector has fallen off, this application provides a water-proof wire harness connector.

[0006] The waterproof wire harness connector provided in this application adopts the following technical solution:

[0007] A water-proof wire harness connector includes a socket and a plug inserted into the socket. An auxiliary plate is fixedly connected inside the socket, and two pins are fixedly connected through the interior of the auxiliary plate. A locking frame is fixedly connected to the outer surface of the socket, and an auxiliary connection mechanism is provided on one side of the locking frame to ensure stable plug insertion.

[0008] By adopting the above technical solution, the auxiliary plate provides a stable support structure for the pins, which helps to reduce the shaking and deformation of the pins during insertion and removal, improve the reliability and service life of the connectors, and the locking frame design helps to fix the position of the plug and socket, preventing them from loosening or falling off during the connection process. This not only improves the stability of the connectors, but also reduces the risk of electrical failures caused by poor connection. The auxiliary connection mechanism is used to fasten the plug, making it stably connected inside the socket.

[0009] Preferably, the auxiliary connection mechanism includes an auxiliary frame, the inner wall of which is symmetrically provided with a sliding groove, a return spring is fixedly connected inside the sliding groove, and a pressure plate is fixedly connected to the end of the return spring away from the inner wall of the sliding groove.

[0010] By adopting the above technical solution, the combination of the return spring and the pressure plate forms a simple locking mechanism. When the plug is inserted into the socket and reaches the predetermined position, the pressure plate locks the plug under the action of the return spring, preventing it from accidentally falling out. This helps improve the connection stability of the connector and ensures the reliability of the electrical connection. Furthermore, when the plug is inserted into the socket, the pressure plate makes tight contact with the plug under the action of the return spring, forming an additional sealing barrier. This helps prevent external substances such as moisture from seeping in through the tiny gaps between the plug and the socket, thereby further enhancing the waterproof performance of the connector.

[0011] Preferably, the socket has a socket hole on the side near the auxiliary frame, and the auxiliary plate has a contact point fixedly connected to the side near the auxiliary frame.

[0012] By adopting the above technical solution, the socket is used to ensure that the plug connection is not deviated, and the contacts are connected to the external circuit to monitor the connection status between the socket and the plug.

[0013] Preferably, an indicator light is fixedly connected to the top surface of the auxiliary frame.

[0014] By adopting the above technical solution, the indicator light can intuitively display the current connection status of the wire harness connector.

[0015] Preferably, a rubber ring is fixedly connected to the inner wall of the auxiliary frame, and a waterstop strip is fixedly connected to the inner wall of the auxiliary frame.

[0016] By adopting the above technical solution, the rubber ring and the water-stop strip together form a multi-layer sealing barrier, effectively preventing external substances such as moisture from seeping in through the tiny gaps between the auxiliary frame and the plug. The rubber ring has good elasticity and sealing performance, and can fit tightly against the outer surface of the plug; while the water-stop strip has the characteristic of swelling when it comes into contact with water, and can expand and fill the gaps after absorbing water, further improving the sealing effect.

[0017] Preferably, the bottom surface of the inner wall of the auxiliary frame is provided with a drainage hole, and the bottom surface of the inner wall of the auxiliary frame is provided with a second sliding groove.

[0018] By adopting the above technical solution, the design of the drainage hole allows water to be smoothly discharged when it accumulates inside the auxiliary frame, preventing water retention from causing internal corrosion or affecting electrical connections. This is especially important for wire harness connectors used in humid or rainy environments. The second groove is used to determine the plug insertion route to prevent deviations that could damage the pins.

[0019] Preferably, one end of the plug is fixedly connected to a wire harness body, and the side of the plug away from the wire harness body is fixedly connected to an auxiliary rod.

[0020] By adopting the above technical solution, the auxiliary rod is used to insert into the socket, further ensuring the tightness of the plug connection.

[0021] Preferably, a slider is fixedly connected to the bottom surface of the plug.

[0022] By adopting the above technical solution, the presence of the slider makes it easier for the plug to be aligned with the socket hole during the plugging process, especially when the plug and socket are at a high position or difficult to reach directly.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The locking frame design helps to secure the position of the plug and socket, preventing them from loosening or falling off during connection. This not only improves the stability of the connector but also reduces the risk of electrical failures due to poor connection.

[0025] 2. The auxiliary connection mechanism utilizes a combination of a return spring and a pressure plate to form a simple locking mechanism. When the plug is inserted into the socket and reaches the predetermined position, the pressure plate, under the action of the return spring, locks the plug, preventing accidental dislodgement. This helps improve the connection stability of the connector and ensures the reliability of the electrical connection. Furthermore, when the plug is inserted into the socket, the pressure plate, under the action of the return spring, makes tight contact with the plug, forming an additional sealing barrier. This helps prevent external substances such as moisture from seeping in through the tiny gaps between the plug and socket, thereby further enhancing the waterproof performance of the connector.

[0026] 3. Indicator lights can visually display the current connection status of the wiring harness connector. For example, when the plug is correctly inserted into the socket and locked, the indicator light will light up, indicating that the connection is normal; conversely, if the plug is not inserted or not locked, the indicator light will turn off to remind the user to check the connection status.

[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] This application discloses a water-proof wire harness connector.

[0036] Reference Figure 1 , Figure 2 A waterproof wire harness connector includes a socket 1 and a plug 6 inserted into the socket 1. An auxiliary plate 2 is fixedly connected inside the socket 1. Two pins 3 are fixedly connected inside the auxiliary plate 2. A locking frame 4 is fixedly connected to the outer surface of the socket 1. An auxiliary connection mechanism 5 is provided on one side of the locking frame 4 to ensure stable insertion of the plug 6. The locking frame 4 is located on the side close to the auxiliary connection mechanism 5. The auxiliary connection mechanism 5 is used to fasten the plug 6 so that it is stably connected inside the socket 1.

[0037] refer to Figure 4 The wire harness body 7 is fixedly connected to one end of the plug 6, and the wire harness body 7 is located on the side away from the socket 1. The plug 6 has a connection hole inside, and the diameter of the connection hole is the same as that of the pin 3. The auxiliary rod 8 is fixedly connected to one end of the plug 6, and the auxiliary rod 8 is located on the side away from the wire harness body 7. The slider 9 is fixedly connected to the bottom surface of the plug 6.

[0038] When the worker inserts the plug 6 into the socket 1, he aligns the slider 9 with the groove 511 on the bottom of the inner wall of the auxiliary frame 51, and then pushes the plug 6 into the socket 1, so that the auxiliary rod 8 is inserted into the socket 56, thereby ensuring that the plug 6 is inserted in the correct position and will not damage the pin 3.

[0039] refer to Figure 3 The auxiliary connection mechanism 5 includes an auxiliary frame 51. A slide groove 52 is symmetrically formed on the inner wall of the auxiliary frame 51. Both sides of the inner wall of the slide groove 52 are fixed to one end of a return spring 53. The other end of the return spring 53 is fixed to the surface of a pressure plate 54. The periphery of the pressure plate 54 contacts the surface of the slide groove 52 and can slide and limit movement. Normally, the pressure plate 54 is located outside the slide groove 52. The pressure plate 54 is fixedly connected to the other end of the return spring 53. The pressure plate 54 is located on the inner wall away from the auxiliary frame 51, and its side has rounded corners. These rounded corners are mainly used to push the pressure plate 54 into the slide groove 52 when the plug 6 is inserted. A socket 56 is formed on one side of the socket 1, and the socket 56 is located on the edge near the pressure plate 54. The diameter of the socket 56 is between 1 cm and 2 cm. The straightness of the auxiliary rod 8... The diameter of the connector 55 is the same as that of the socket 56. The contact 55 is fixedly connected to one side of the auxiliary plate 2. The contact 55 is located near the auxiliary connection mechanism 5 and below the pin 3. The indicator light 57 is fixedly connected to the top surface of the auxiliary frame 51. The indicator light 57 is electrically connected to the contact 55. The function of the contact 55 in the circuit is to control the current flow. When the plug 6 contacts the contact 55, the contact 55 closes, and the current flows through, thus illuminating the indicator light 57. When the plug 6 does not contact the contact 55, the contact 55 opens, the current is interrupted, and the indicator light 57 goes out. The contact 55 is a contact sensor. For example, when the plug 6 is correctly inserted into the socket 1 and locked, the indicator light 57 lights up, indicating that the connection is normal. Conversely, if the plug 6 is not inserted or not locked, the indicator light 57 goes out to remind the user to check the connection status.

[0040] When the plug 6 moves into the socket 1, the outer surface of the plug 6 presses against the rounded corner pressure plate 54. When the pressure plate 54 is pressed, it presses against the return spring 53, compressing it. The return spring 53 also provides the opposite force to the pressure plate 54, so that the pressure plate 54 always fits against the outer surface of the plug 6, making the connection of the plug 6 more stable. When the pin 3 is inserted into the inside of the plug 6, the plug 6 contacts the contact point 55, thereby illuminating the indicator light 57, which can intuitively display the current connection status of the wire harness connector.

[0041] Rubber ring 58 is fixedly connected to the inner wall of auxiliary frame 51. When plug 6 is inserted into socket 1, rubber ring 58 is always tightly attached to the outer surface of plug 6 to ensure the sealing degree of plug 6 and socket 1. Water-stop strip 59 is fixedly connected to the inner wall of auxiliary frame 51 and is located on the side away from auxiliary frame 51. Water-stop strip 59 is made of water-absorbing and expanding material, such as water-absorbing resin. Drainage hole 510 is opened on the bottom surface of inner wall of auxiliary frame 51 and is located on both sides of water-stop strip 59. Slide groove 2 511 is opened on the bottom surface of inner wall of auxiliary frame 51 and is adapted to the size of slider 9.

[0042] When the plug 6 is inserted into the socket 1 and the socket 1 is exposed to water, the water-stop strip 59 will absorb water and expand, making the socket 1 and the plug 6 a sealed space. The bottom of the inner wall of the auxiliary frame 51 is provided with a drain hole 510. When there is a large amount of water, the water can flow out from the drain hole 510. In addition, the inner wall of the auxiliary frame 51 is also fixedly connected with a rubber ring 58, which can further ensure the sealing of the socket 1.

[0043] Contact 55 and indicator light 57 are existing technologies, and their structural principles will not be elaborated here.

[0044] The implementation principle of a water-proof wire harness connector according to an embodiment of this application is as follows:

[0045] When in use, the operator inserts the plug 6 into the socket 1, aligns the slider 9 with the groove 511 on the bottom of the inner wall of the auxiliary frame 51, and then pushes the plug 6 into the socket, so that the auxiliary rod 8 is inserted into the socket 56. This ensures that the plug 6 is inserted accurately and will not damage the pin 3. When the plug 6 moves into the socket 1, the outer surface of the plug 6 will press the rounded corner pressure plate 54. When the pressure plate 54 is pressed, it will press the return spring 53, compressing it. The return spring 53 will also provide the opposite force to the pressure plate 54, so that the pressure plate 54 always fits against the outer surface of the plug 6, making the connection of the plug 6 more stable. When the pin 3 is inserted into the inside of the plug 6, the plug 6 contacts the contact point 55, thereby lighting up the indicator light 57, which can intuitively display the current connection status of the wire harness connector.

[0046] When the plug 6 is inserted into the socket 1 and the socket 1 is exposed to water, the water-stop strip 59 will absorb water and expand, making the socket 1 and the plug 6 a sealed space. The bottom of the inner wall of the auxiliary frame 51 is provided with a drain hole 510. When there is a large amount of water, the water can flow out from the drain hole 510. In addition, the inner wall of the auxiliary frame 51 is also fixedly connected with a rubber ring 58, which can further ensure the sealing of the socket 1.

[0047] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
