Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a high-sealing wire harness female connector. Background Technology

[0002] A wire harness connector is an electrical component used to enable detachable and connectable connections between wires in an electrical circuit, or between a wire and a device or component. It is a key interface component for ensuring circuit continuity, signal transmission, and power supply. It typically consists of two parts: a male connector and a female connector, which are used to achieve quick connection and disconnection through a plug-in mating method.

[0003] In existing automotive wiring harness connectors, although a sealing sleeve is set between the housing and the wiring harness to provide waterproof and dustproof protection, the sealing effect is relatively limited. At the same time, the mating parts of male and female connectors generally lack a dedicated sealing structure. As the requirements for waterproof and dustproof performance of new energy intelligent vehicles continue to increase, we propose a high-sealing female wiring harness connector to meet this need. Utility Model Content

[0004] To address the aforementioned issue of insufficient sealing, this application provides a high-sealing wire harness female connector.

[0005] The high-sealing wire harness female connector provided in this application adopts the following technical solution:

[0006] A high-sealing wire harness female connector includes a wire, one end of which is fixedly connected to a male connector, and one end of the male connector is provided with a female connector. A pin is fixedly connected to one end of the male connector. The female connector has a pin seat inside, and a pin is provided in the inner cavity of the pin seat. An extension block is fixedly connected to the side of the male connector near the female connector. A first mounting cavity is provided between the extension block and the pin. A retaining block is fixedly connected to the inner wall of the extension block. A second mounting cavity is provided inside the female connector. A straight groove is provided inside the second mounting cavity, and a curved groove is provided at the end of the straight groove. The diameter of the retaining block is equal to the width of the straight groove.

[0007] Preferably, the extension block is located inside the second mounting cavity, the locking blocks are evenly distributed circumferentially along the inner wall of the extension block, and the orientation of each locking block is perpendicular to the axis of the pin.

[0008] Preferably, a rubber block is fixedly connected to the front end of the inner wall of the female connector, and an installation groove is provided on the outer wall of the male connector. When the male connector is connected to the female connector, the rubber block is pressed into the installation groove.

[0009] Preferably, the outer wall of the female connector is slidably connected to a movable sleeve, one end of the movable sleeve is rotatably connected to a rotating shaft, and the other end of the rotating shaft is rotatably connected to a fixed sleeve. The fixed sleeve has an external thread inside, and the outer wall of the female connector has an internal thread. The internal thread and the external thread mesh with each other.

[0010] Preferably, a gap is provided between the outer wall of the extension block and the inner wall of the second mounting cavity, the width of the gap being 0.1-0.3 mm, and the gap is filled with high-temperature resistant sealing grease.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. A stable electrical connection is achieved through precise docking of the pin and the pin seat. The extension block and the second mounting cavity cooperate to provide guidance. The locking blocks are evenly distributed around the extension block and perpendicular to the pin axis, which can smoothly slide into the straight groove and reliably lock into the curved groove, avoiding axial separation of the male and female connectors.

[0013] 2. When the male connector is connected to the female connector, the rubber block on the inner wall of the female connector will press against the mounting groove of the male connector. The elasticity of the rubber tightly fills the gap, creating the first line of defense against dust and moisture. In addition, the pressing action of the fixed sleeve on the connection part allows the connector to be stably used in harsh working conditions such as humidity, dust, and high temperature, greatly expanding its application range.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1-4 This utility model provides a high-sealing wire harness female connector, including a wire 1, one end of which is fixedly connected to a male connector 101, one end of which is provided with a female connector 102, and one end of which is fixedly connected to a pin 103. The female connector 102 has a pin seat 104 inside, and the inner cavity of the pin seat 104 is provided with the pin 103. An extension block 2 is fixedly connected to the side of the male connector 101 near the female connector 102. A first mounting cavity 201 is provided between the extension block 2 and the pin 103. A locking block 202 is fixedly connected to the inner wall of the extension block 2. The female connector 102 has a second mounting cavity 203 inside, and a straight groove 204 is provided inside the second mounting cavity 203. The end of the straight groove 204 is provided with a bent groove 205. The diameter of the locking block 202 is equal to the width of the straight groove 204.

[0021] The operator moves the male connector 101 toward the female connector 102, aligning the pin 103 fixedly connected to one end of the male connector 101 with the pin seat 104 inside the female connector 102. As the male connector 101 and the female connector 102 approach each other, the pin 103 gradually inserts into the inner cavity of the pin seat 104, eventually forming a stable electrical connection between the pin 103 and the pin seat 104, enabling signal or current transmission between the wire 1 and the external circuit. During the process of the male connector 101 approaching the female connector 102, the extension block 2 fixedly connected to one side of the male connector 101 simultaneously enters the second mounting cavity 203 inside the female connector 102. The first mounting cavity 201 between the extension block 2 and the pin 103 prevents interference between them and also reserves space for possible subsequent sealing structure installation. The retaining block 202 fixedly connected to the inner wall of the extension block 2 first enters the straight groove 204 inside the second mounting cavity 203. Due to the diameter of the retaining block 202... Equal in width to the straight groove 204, the locking block 202 can slide stably along the straight groove 204. When the locking block 202 slides to the end of the straight groove 204, the operator rotates the male connector 101, causing the extension block 2 and the locking block 202 to rotate synchronously, so that the locking block 202 enters the curved groove 205 provided at the end of the straight groove 204. The curved groove 205 limits the locking block 202, preventing the male connector 101 and the female connector 102 from axially separating during the operation, and finally completing the docking installation of the male connector 101 and the female connector 102.

[0022] In a preferred embodiment, the extension block 2 is located inside the second mounting cavity 203, and the locking blocks 202 are evenly distributed circumferentially along the inner wall of the extension block 2, and the orientation of each locking block 202 is perpendicular to the axis of the pin 103.

[0023] During the connection process between the male connector 101 and the female connector 102, the extension block 2 enters the second mounting cavity 203 of the female connector 102. Since the locking blocks 202 are evenly distributed circumferentially along the inner wall of the extension block 2, and the orientation of each locking block 202 is perpendicular to the axis of the pin 103, when the male connector 101 is inserted into the female connector 102, the locking blocks 202 smoothly enter the straight groove 204 within the second mounting cavity 203. When the male connector 101 is rotated to allow the locking blocks 202 to enter the curved groove 205, the evenly distributed locking blocks 202 can bear force evenly, ensuring the smooth rotation of the male connector 101 and locking the two connectors together.

[0024] In a preferred embodiment, a rubber block 206 is fixedly connected to the front end of the inner wall of the female connector 102, and an installation groove 207 is provided on the outer wall of the male connector 101. When the male connector 101 is connected to the female connector 102, the rubber block 206 is pressed into the installation groove 207.

[0025] When the male connector 101 is connected to the female connector 102, the rubber block 206 at the front end of the inner wall of the female connector 102 is squeezed by the outer wall of the male connector 101. As the male connector 101 continues to be inserted, the rubber block 206 is pressed into the mounting groove 207 on the outer wall of the male connector 101. The rubber block 206 undergoes elastic deformation, tightly filling the mounting groove 207, preventing external dust, moisture, and other impurities from entering the connector.

[0026] In a preferred embodiment, a movable sleeve 3 is slidably connected to the outer wall of the female connector 102. One end of the movable sleeve 3 is rotatably connected to a rotating shaft 301, and the other end of the rotating shaft 301 is rotatably connected to a fixed sleeve 302. The fixed sleeve 302 is provided with an external thread 303 inside, and the outer wall of the female connector 102 is provided with an internal thread 304. The internal thread 304 and the external thread 303 mesh with each other.

[0027] After the male connector 101 and the female connector 102 are connected, the fixed sleeve 302 can be rotated to further enhance the stability and sealing of the connection. Since the fixed sleeve 302 has an external thread 303 inside, and the outer wall of the female connector 102 has an internal thread 304, and the internal thread 304 meshes with the external thread 303, when the fixed sleeve 302 is rotated, it will move axially along the female connector 102. The movable sleeve 3 is slidably connected to the outer wall of the female connector 102 and is rotatably connected to the fixed sleeve 302 via a rotating shaft 301. During the movement of the fixed sleeve 302, the movable sleeve 3 will move accordingly and press against the connection between the male connector 101 and the female connector 102, thus providing reinforcement and sealing.

[0028] In a preferred embodiment, a gap is provided between the outer wall of the extension block 2 and the inner wall of the second mounting cavity 203, the gap being 0.1-0.3 mm wide and filled with high-temperature resistant sealing grease.

[0029] This gap provides space for the extension block 2 to be installed in the second mounting cavity 203, avoiding the extension block 2 from failing to enter the second mounting cavity 203 smoothly due to processing errors or from being deformed due to excessive compression against the inner wall of the second mounting cavity 203.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
