Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more specifically, to a wire harness connector. Background Technology

[0002] As a key component for wire harness connections in electrical systems, wire harness connectors are widely used in many fields such as automobiles, electronic equipment, and home appliances, undertaking important functions of signal transmission and power delivery. However, existing wire harness connectors have many problems in actual use. On the one hand, the insertion and extraction structure of most connectors is not reasonably designed, with excessive or insufficient insertion and extraction force. Excessive insertion and extraction force not only increases the difficulty of installation and maintenance, but may also damage the wire harness or connector itself; insufficient insertion and extraction force makes the connectors prone to loosening and falling off under vibration, shaking and other environments, resulting in unstable circuit connections and affecting the normal operation of equipment.

[0003] Patent CN101931139B discloses a reliable and fast wiring harness connector. This connector includes a body connector and a battery pack connector. The body connector comprises a body connection base and a body connector itself. The body connection base and the body connector have corresponding connection holes. They are connected by bolts passing through the connection holes. The bolt's body diameter is smaller than the connection hole diameter, while the bolt head and the nut that mates with the bolt have diameters larger than the connection hole diameter. A spring is fitted onto the bolt, with both ends abutting against the body connection base and the body connector, respectively. The body connector has a connection terminal and a locating pin hole aligned with the spring direction. The battery pack connector has a connection terminal and a locating pin that mate with the connection terminal and locating pin hole of the body connector. This invention provides a simple and reliable wiring harness connector, reducing the number of connectors required and thus saving costs and time in installing and removing the battery pack.

[0004] While this technical solution offers advantages such as cost savings and reduced battery pack installation / removal time, most current wiring harness connectors, although concentrating the wiring harness on corresponding plugs and sockets for convenient connection, lack adequate sealing at the connection points. This inadequate waterproofing allows rainwater to penetrate, posing a safety hazard. Therefore, we propose a new wiring harness connector. Utility Model Content

[0005] The purpose of this utility model is to provide a wire harness connector to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wire harness connector includes a socket and a plug that engages with the socket. Both the socket and the plug are electrically connected to multiple corresponding wire harnesses. An end plate is fixedly mounted on the rear end of the plug. Side plates are fixedly mounted on both the left and right sides of the end plate. Side sleeves are fixedly mounted on both the left and right sides of the socket. Multiple heat dissipation holes communicating with the interior of the side sleeves are provided on the inner walls of both sides of the socket. Multiple heat sinks are fixedly mounted on the side surfaces of the side sleeves. The side plates are detachably mounted on the front surface of the side sleeves. A sealing gasket is fitted onto the plug for sealing between the socket and the plug.

[0007] Preferably, the socket has a front-side connection hole that communicates with the outside, and the plug is located inside the connection hole and is inserted into the connection hole.

[0008] Preferably, an inner cavity is provided inside the side sleeve, and the heat dissipation hole is connected to the inner cavity; Preferably, a portion of the heat sink plate is located outside the side sleeve, and the remaining portion of the heat sink plate extends into the inner cavity. The above two settings facilitate heat conduction at the heat sink.

[0009] Preferably, the size of the sealing gasket is adapted to the size of the plug, and the end plate presses the sealing gasket against the front side of the socket; This feature provides good waterproof protection.

[0010] Preferably, multiple protrusions are integrally formed on both the top and bottom surfaces of the end plate, and the protrusions are located outside the front projection of the socket; This feature allows the force applied by the palm of the hand to the protrusion when the plug is subsequently unplugged.

[0011] Preferably, an end reinforcement sleeve is fixedly installed between the end of the wire harness and the corresponding socket or plug, and the outer diameter of the end reinforcement sleeve is larger than the outer diameter of the wire harness.

[0012] Preferably, the side plate and the side sleeve are detachably connected by fastening screws, and the fastening screws are fitted with elastic washers.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves effective sealing of the connection between the socket and the plug by fitting a sealing gasket that matches the plug size onto the plug and pressing the sealing gasket tightly against the front side of the socket using an end plate. This solves the problem of poor waterproofing at the connection points of existing connectors. When rainwater or other external liquids come into contact with the connector, the sealing gasket can prevent them from entering the interior, effectively eliminating the risk of short circuits and other safety hazards caused by liquid intrusion, and greatly improving the safety and reliability of wire harness connectors in humid environments.

[0014] 2. This utility model features multiple protrusions integrally formed on the top and bottom surfaces of the end plate, located outside the front projection of the socket. This allows the palm to easily apply force to the protrusions when unplugging the plug, providing a good point of leverage and changing the inconvenience of applying force in traditional plugging and unplugging methods, thus reducing the difficulty of plugging and unplugging. Combined with the design of the side plate and side sleeve being detachably connected by fastening screws, the plug and socket can be accurately positioned and firmly fixed during installation, and disassembly is also easier, significantly improving the convenience and efficiency of wire harness connector installation and maintenance.

[0015] 3. This utility model features a highly efficient heat dissipation channel created by providing heat dissipation holes that communicate with the interior of the side sleeve on the inner walls of the left and right sides of the socket, and installing heat sinks on the sides of the side sleeve, with some of the heat sinks located on the outside and others extending into the inner cavity. This design effectively dissipates heat generated during the insertion process, preventing heat accumulation from affecting the performance and lifespan of the connector. Simultaneously, a reinforcing sleeve with an outer diameter larger than the wire harness cable is installed between the wire harness cable end and the socket / plug, enhancing the firmness of the connection between the wire harness and the connector, preventing the wire harness from loosening or falling off due to external pulling, and further ensuring the stability of the electrical connection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a wire harness connector, including a socket 1 and a plug 20 that is plugged into the socket 1. The socket 1 has a plug hole 10 that is connected to the outside on the front side. The plug 20 is located in the plug hole 10 and is plugged into the plug hole 10. Multiple corresponding wire harnesses 3 are electrically connected to both the socket 1 and the plug 20. An end plate 2 is fixedly installed at the rear end of the plug 20. Side plates 23 are fixedly installed on both the left and right sides of the end plate 2. Side sleeves 12 are fixedly installed on both the left and right sides of the socket 1. A sealing gasket 21 is fitted on the plug 20. The sealing gasket 21 is used for sealing between the socket 1 and the plug 20. The size of the sealing gasket 21 is adapted to the size of the plug 20. The end plate 2 presses the sealing gasket 21 tightly against the front side of the socket 1, so that the sealing gasket 21 fits tightly against the connection part of the socket 1 and the plug 20, thereby achieving effective sealing of the connection part. This design solves the problem of poor waterproofing of existing connectors. When rainwater or other external liquids come into contact with the connector, the sealing gasket 21 can prevent them from entering the interior, effectively eliminating the risk of short circuits and other safety hazards caused by liquid intrusion, and greatly improving the safety and reliability of wire harness connectors in humid environments.

[0019] In this embodiment, multiple heat dissipation holes 11 communicating with the interior of the side sleeve 12 are provided on the inner walls of both the left and right sides of the socket 1. Multiple heat sinks 13 are fixedly installed on the side of the side sleeve 12. The side plate 23 is detachably installed on the front side of the side sleeve 12. An inner cavity 121 is provided inside the side sleeve 12, and the heat dissipation holes 11 communicate with the inner cavity 121. Part of the heat sink 13 is located outside the side sleeve 12, and the remaining part of the heat sink 13 extends into the inner cavity 121, forming an efficient heat dissipation channel. This structure can dissipate the heat generated during the insertion process in a timely manner, avoiding the impact of heat accumulation on the performance and service life of the connector.

[0020] like Figure 2 As shown, multiple protrusions 22 are integrally formed on the top and bottom surfaces of the end plate 2. The protrusions 22 are located outside the front projection of the socket 1, so that when the plug 20 is pulled out, the palm can easily apply force to the protrusions 22, providing a good point of force.

[0021] like Figure 2As shown, an end reinforcement sleeve 30 is fixedly installed between the end of the wire harness cable 3 and the corresponding socket 1 and plug 20. The outer diameter of the end reinforcement sleeve 30 is larger than the outer diameter of the wire harness cable 3, which enhances the firmness of the connection between the wire harness and the connector, prevents the wire harness from loosening or falling off due to external pulling, and further ensures the stability of the electrical connection.

[0022] In this embodiment, the side plate 23 and the side sleeve 12 are detachably connected by fastening screws 24. The fastening screws 24 are fitted with elastic washers 25 to facilitate fixing and prevent them from falling off.

[0023] Finally, it should be noted that the plug 20, socket 1, and wire harness cable 3 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0024] When using the wire harness connector of this utility model, the sealing gasket 21 is put on the plug 20, the plug 20 is aligned with the plug hole 10 of the socket 1, and the plug 20 is smoothly inserted into the plug hole 10. After the plug 20 is fully inserted, the end plate 2 presses the sealing gasket 21 tightly on the front side of the socket 1 to complete the sealing operation and prevent external liquid from entering. Then, the side plates 23 on both sides of the end plate 2 are aligned with the side sleeves 12 on both sides of the socket 1. The side plates 23 are fixed on the front side of the side sleeves 12 using the fastening screws 24 and the elastic washers 25, further strengthening the connection between the plug 20 and the socket 1. During use, if the connector generates heat, the heat will be transferred through the heat dissipation holes 11 on the inner wall of the socket 1 to the inner cavity 121 of the side sleeve 12, and dissipated to the outside with the help of the heat sink 13. When disassembly is required, unscrew the fastening screws 24, hold the protrusion 22 on the end plate 2, and apply force to pull the plug 20 out of the socket 1's plug hole 10.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
