Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an automotive-grade waterproof connector structure. Background Art

[0002] An automotive-grade connector is a connector that meets automotive standards. On the one hand, based on the working conditions and environment of the vehicle, automotive-grade connectors have strict requirements for anti-loosening, waterproofing, and durability. In existing connectors, in order to prevent loosening after high-intensity pulling, the male and female parts of the connector are generally connected and fixed by a bolt structure. When both ends of the connector are subjected to tension, the bolt structure serves as a tensile connector. The shortcomings of this connector structure are: 1. The connection structures used to connect the male and female ends need to be exposed, lack protection, and are prone to aging or rust, which in turn affects the connection strength and service life. 2. When the male and female plugs are disassembled, they need to be rotated multiple times, which increases the difficulty of disassembly and reduces the disassembly rate. 3. The exposed connector makes the entire connector body uneven and easy to adhere to dust and dirt.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 17 As shown, a vehicle-grade waterproof connector structure described in the present invention includes a female plug-in and a male plug-in; the female plug-in includes a connecting seat 6; a first rubber-coated head 1 is connected to the connecting seat 6; the male plug-in is a second rubber-coated head 3; a connector slot 601 is provided on the side surface of the connecting seat 6; the connector slot 601 penetrates to an end face of the connecting seat 6; a connector 302 is provided on the second rubber-coated head 3; a second spring conductive sheet body 9 is provided on the side wall of the connector slot 601; a conductive block 303 is provided on the front end face of the connector 302; the connector 302 is buckled into the connector slot 601, and the conductive block 303 is connected to the second spring conductive sheet body 9; a sliding sleeve 2 is slidably connected to the connecting seat 6; the sliding sleeve 2 is sleeved on the outside of the connecting position between the connector 302 and the connector slot 601 and then pressed against the end face of the second rubber-coated head 3; an elastic blocking component for blocking the sliding sleeve 2 from sliding away from the second rubber-coated head 3 is provided on the connecting seat 6; After one end of the first rubber packing head 1 is embedded in the positioning groove 608 provided on the connecting seat 6, the first rubber packing head 1 and the connecting seat 6 are connected as a whole by screws; the joint 302 and the second rubber packing head 3 are formed as a whole; The connection between the female plug-in and the male plug-in is achieved by inserting the connector 302 from the side surface of the connection seat 6 into the connector slot 601 for positioning. When the female plug-in and the male plug-in are pulled, the insertion direction of the connector 302 into the connector slot 601 is perpendicular to the pulling direction of the female plug-in and the male plug-in; therefore, even after being pulled, the connector 302 will not be pulled out along the direction of insertion into the connector slot 601. The structure of the male plug and the female plug is used as a positioning structure for connection. Finally, the sliding sleeve 2 seals and blocks the end surface of the connector slot 601, further preventing the connector 302 from being pulled out laterally from the connector slot 601. When the connector is pulled, the sliding sleeve 2 will not be subjected to a force in the sliding direction of the sliding sleeve 2 , so the sliding sleeve 2 can be positioned on the connecting seat 6 only by the blocking force of the elastic blocking component.

[0021] As a preferred embodiment of the present invention, a block 601a is provided on the inner side wall of the connector slot 601; a positioning block 302a is provided on the surface of the connector 302; a positioning inclined surface 601a1 is provided on the surface of the block 601a close to the second spring conductive sheet body 9; the positioning inclined surface 601a1 is inclined toward one side of the bottom surface of the connector slot 601; the side surface of the positioning block 302a is provided with a chamfered surface 302a1 matching the positioning inclined surface 601a1; The angle between the positioning inclined surface 601a1 and the bottom surface of the connector slot 601 is an acute angle; When the number of the clamping block 601a and the number of the positioning block 302a are one, the connector clamping slot 601 and the connector 302 are both in an "L" shape; The number of the clamping blocks 601a can be two, and they are arranged symmetrically on both sides. The number of the positioning blocks 302a is also two, and they are arranged symmetrically. In this way, the connector slot 601 and the connector 302 are both in a "T" shape. The connector slot 601 is formed into a slot hole with a corner by the clamping block 601a, and the positioning block 302a is fastened on the clamping block 601a for positioning, so that after the connector receives a pulling force, the connector 302 will not be loosened from the connector slot 601; and the side surface of the positioning block 302a is provided with a chamfered surface 302a1 that matches the positioning inclined surface 601a1. When there is no pulling force, the elastic force of the second spring conductive sheet body 9 presses the front of the conductive block 303, and its force acts on the positioning inclined surface 601a1, which also pushes the connector 302 to slide downward along the positioning inclined surface 601a1, so as to achieve the initial self-locking of the connector slot 601 and the connector 302. When the two ends of the connector are subjected to tension, the wedge-shaped structure formed by the positioning inclined surface 601 a 1 and the chamfered surface 302 a 1 pulls the connector 302 downward, making it more difficult for the connector 302 to loosen from the connector slot 601 .

[0022] As a preferred embodiment of the present invention, a connection slot 606 is provided on the side of the connection seat 6 away from the connector slot 601; the second spring conductive sheet body 9 is provided in the connection slot 606; the inner bottom wall of the connection slot 606 is provided with a rear slot 603 and a front slot 605; the rear slot 603 is connected to the connector slot 601; one end of the second spring conductive sheet body 9 extends from the rear slot 603 into the connector slot 601; the other end of the second spring conductive sheet body 9 extends into the front slot 605; the first rubber-wrapped head 1 A first spring conductive sheet 7 is fixed inside; the end of the first spring conductive sheet 7 extends into the front slot 605; a sliding seat 8 is slidably connected in the front slot 605; one end of the first spring conductive sheet 7 extending into the front slot 605 and one end of the second spring conductive sheet body 9 extending into the front slot 605 are respectively arranged on both sides of the sliding seat 8; a push-pull component for pulling the sliding seat 8 to perform lifting movement in the front slot 605 is arranged on the sliding sleeve 2; the sliding seat 8 is provided with conductive columns 801 that penetrate the two end surfaces of the sliding seat 8; When the connector is in normal use, the sliding sleeve 2 is sleeved outside the connection position between the connector 302 and the connector slot 601; the sliding sleeve 2 pushes the sliding seat 8 to slide in the front slot 605, so that the conductive column 801 connects the end of the first spring conductive sheet 7 that extends into the front slot 605 and the end of the second spring conductive sheet body 9 that extends into the front slot 605. When the sliding sleeve 2 is pulled out to be misaligned with the connector slot 601 and the connector slot 601 is exposed, the sliding sleeve 2 pushes the sliding seat 8 to slide in the front slot 605, so that the end of the first spring conductive sheet 7 that extends into the front slot 605 and the end of the second spring conductive sheet body 9 that extends into the front slot 605 are misaligned with the conductive column 801, and the exposed second spring conductive sheet body 9 is disconnected from the first spring conductive sheet 7 connected to the power supply; Therefore, the exposed connector slot 601 and the second spring conductive sheet body 9 inside thereof will not be energized, so that neither a short circuit due to an accidental touch nor a spark will be generated when the connector 302 is instantly energized when inserted into the connector slot 601, thereby ensuring the safety of the detection environment. Therefore, during detection, there is no need to frequently disconnect the main power switch, thereby improving the detection efficiency.

[0023] As a preferred embodiment of the present invention, the first spring conductive sheet 7 is extended into the front slot 605 and is provided with an elastic part 702 at one end; the push-pull assembly is a convex strip 202 provided on the inner wall of the sliding sleeve 2; the convex strip 202 extends into the connecting groove 606; the surface of the convex strip 202 and the end of the elastic part 702 are respectively pressed against the upper and lower ends of the sliding seat 8; the convex strip 202 is provided with a convex table surface 202a; a transition inclined surface 202c is provided between the surface of the convex strip 202 and the convex table surface 202a; the elastic part 702 is formed by bending the end of the first spring conductive sheet 7; The main body of the sliding seat 8 is made of non-conductive material; the connecting seat 6 is provided with a convex groove 604 for passing the convex strip 202. Under the action of the elastic part 702, the sliding seat 8 is pressed against the surface of the convex strip 202; when the sliding sleeve 2 is sleeved on the external state of the connection position between the connector 302 and the connector slot 601, the convex table surface 202a part contacts the sliding seat 8, and the conductive column 801 on the sliding seat 8 connects the first spring conductive sheet 7 and the second spring conductive sheet body 9. However, after the sliding sleeve 2 slides to be misaligned with the connector slot 601, the sliding seat 8 is aligned with the lower part of the convex strip 202, and the sliding seat 8 is pushed downward by the elastic part 702, so that the conductive column 801 is misaligned with the conductive position of the first spring conductive sheet 7 and the conductive position of the second spring conductive sheet body 9, so that the first spring conductive sheet 7 is disconnected from the second spring conductive sheet body 9.

[0024] The structure for pushing the sliding seat 8 is completely arranged inside the sliding sleeve 2, so as to improve its waterproof performance and make the surface of the entire connector smoother and less prone to dust. Moreover, it can be realized that after the sliding sleeve 2 is pulled out to be misaligned with the connector slot 601, the second spring conductive sheet body 9 is immediately powered off; after the connector slot 601 is aligned with the sliding sleeve 2, the second spring conductive sheet body 9 is immediately powered on, which is safer to use. The combination of the sliding seat 8 and the conductive column 801 adopts an insert injection molding process; The elastic part 702 for providing elastic force to the sliding seat 8 is directly formed by bending the original structure of the first spring conductive sheet 7, which simplifies the entire structure and improves the installation efficiency of the connector.

[0025] As a preferred embodiment of the present invention, the sliding seat 8 is the elastic blocking component; The bottom surface of the sliding seat 8 is in an arc shape; the top surface of the boss surface 202a is provided with an arc positioning concave 202b; when the sliding sleeve 2 slides to the outer state of the connection position between the connector 302 and the connector slot 601, the bottom of the sliding seat 8 will be pressed into the arc positioning concave 202b due to the elastic force of the elastic part 702, so that the sliding sleeve 2 is not easy to slide relative to the connecting seat 6. When the sliding sleeve 2 needs to be pulled, a certain thrust is required to push the sliding sleeve 2, so that the sliding seat 8 with an arc bottom surface slides along the inclined surface of the arc positioning concave 202b, and the bottom of the sliding seat 8 is squeezed by the inclined surface of the arc positioning concave 202b, and the elastic part 702 is compressed, so that the sliding seat 8 is first separated from the arc positioning concave 202b. The sliding seat 8 is used as an elastic blocking component, so that the sliding seat 8 has the function of connecting the circuit and positioning the sliding sleeve 2.

[0026] As a preferred embodiment of the present invention, semi-cylinders 802 are provided on both the left and right surfaces of the sliding seat 8; the semi-cylinders 802 and the conductive columns 801 are alternately distributed; the surfaces of the semi-cylinders 802 on both sides are respectively attached to the two inner side walls of the front slot 605; The sliding of the sliding seat 8 and the front slot 605 can be achieved by setting a semi-cylinder 802 on the sliding seat 8. On the one hand, the friction between the sliding seat 8 and the front slot 605 can be reduced, making the sliding of the sliding seat 8 smoother. On the other hand, the semi-cylinder 802 can be used to separate the adjacent first spring conductive sheet body 7 and the adjacent second spring conductive sheet body 9, further reducing the risk of short circuit.

[0027] As a preferred embodiment of the present invention, the first spring conductive sheet body 7 and the second spring conductive sheet body 9 are both in a "U" shape; The second spring conductive sheet body 9 extends into the rear slot 603 and is provided with a second spring conductive sheet 901 at one end; the second spring conductive sheet body 9 extends into the front slot 605 and is provided with a third spring conductive sheet 902 at one end; the first spring conductive sheet body 7 extends into the front slot 605 and is provided with a first spring conductive sheet 701 at one end; the other end of the first spring conductive sheet body 7 is provided with a wire connection sleeve 703; the wire connection sleeve 703 is arranged in the first rubber bag head 1; a limiting groove 607 is provided on the connection groove 606; the first spring conductive sheet body 7 is respectively embedded in the limiting groove 607; one of the wires of the connector is first connected to the wire connection sleeve 703, and then wrapped and fixed in the first rubber bag head 1 by using the insert injection molding process; the other wire of the connector is connected to the conductive block 303, and then fixed to the second rubber bag head 3 by using the insert injection molding process; the first rubber bag head 1 and the second rubber bag head 3 are both formed by injection molding; The wire connection sleeve 703, the first spring conductive sheet 701 and the elastic part 702 are formed by bending a conductive sheet in one piece, and the second spring conductive sheet 901 and the third spring conductive sheet 902 are formed by bending a conductive sheet in one piece, so that the processing of the conductive structure is simpler.

[0028] As a preferred embodiment of the present invention, a second retaining ring 301 is provided on the second rubber bag head 3; a second positioning column 301a is provided on the front end surface of the second retaining ring 301; a first sealing ring 4 is sleeved on the second positioning column 301a; a first retaining ring 203 is provided on the end of the sliding sleeve 2 away from the second rubber bag head 3; a first positioning column 101 is provided on the first rubber bag head 1; a second sealing ring 5 is sleeved on the first positioning column 101; the first retaining ring 203 presses the second sealing ring 5 onto the first rubber bag head 1; the sliding sleeve 2 presses the first sealing ring 4 onto the second retaining ring 301; The combination of the first spring conductive sheet 7 and the first rubber-coated head 1 and the combination of the second rubber-coated head 3 and the conductive block 303 adopts an insert injection molding process; The second sealing ring 5 is used to seal the gap between the first rubber packing head 1 and the first retaining ring 203; the first sealing ring 4 is used to seal the gap between the end surface of the sliding sleeve 2 and the second retaining ring 301; After the sliding sleeve 2 is positioned, the gaps in front and behind the sliding sleeve 2 are sealed by the first sealing ring 4 and the second sealing ring 5 respectively, which can ensure the waterproof ability of the internal circuit; and the sliding sleeve 2 is an integrated structure, and except for the two end faces with sealing rings, the other positions of the sliding sleeve 2 do not have threaded holes or gaps. When waterproofing the circuit, only the two end faces of the sliding sleeve 2 need to be considered, and the waterproof structure design of the connector is simpler.

[0029] As a preferred embodiment of the present invention, this structure is another scheme of the elastic blocking component, a straight groove 602 is provided on the surface of the connecting seat 6 with the joint slot 601; the straight groove 602 extends along the sliding direction of the sliding sleeve 2; the elastic blocking component is a silicone rubber band 10; a hook 204 is provided on the inner wall of the sliding sleeve 2; the two ends of the silicone rubber band 10 are respectively fixed on both sides of the straight groove 602; the hook 204 is inserted into the straight groove 602; the hook 204 is hooked in the middle of the silicone rubber band 10; the silicone rubber band 10 provides the hook 204 with a pulling force in the direction of the second rubber bag head 3; clamping columns 602a are provided on both sides of the straight groove 602; ferrules are provided at both ends of the silicone rubber band 10; the ferrules at both ends are respectively inserted into the clamping columns 602a for fixing; The depth of the straight groove 602 needs to be greater than the sum of the diameter of the silicone rubber band 10 and the height of the hook 204 to ensure that the silicone rubber band 10 can pass through the gap between the hook 204 and the inner bottom wall of the straight groove 602 and be buckled on the hook 204 during assembly. In addition, for the convenience of assembly, the straight groove 602 passes through the end face close to the second rubber bag head 3, so that the tool for hanging the silicone rubber band 10 can be inserted into the straight groove 602 to buckle the silicone rubber band 10 on the hook 204; the silicone rubber band 10 will not be unhooked after being buckled on the hook 204 for the first time. When used in the future, the silicone rubber band 10 continuously provides a force to the sliding sleeve 2 with the hook 204 to prevent the sliding sleeve 2 from sliding away from the second rubber bag head 3; in addition, in order to simplify the mold structure of the molding sliding sleeve 2, a process hole 203a opposite to the hook 204 is opened on the second rubber bag head 3, so that the molding of the hook 204 is simpler; and a sealing block 501 for sealing the process hole 203a is provided on the second sealing ring 5.

[0030] As a preferred embodiment of the present invention, a plurality of handle holes 201 are provided on the surface of the sliding sleeve 2 .

[0031] The beneficial effects of the present invention are: 1. The connection structure of the female plug-in and the male plug-in is composed of a connector with a "T" or "L" cross-section inserted into the matching connector slot to enhance the connection strength. The sliding sleeve blocks the seal to prevent the connection structure used to withstand tension from being exposed to the outside, reduce the aging speed, ensure the connection strength, and increase the service life.

[0032] 2. When the female plug-in and the male plug-in are disassembled, it is only necessary to overcome the resistance of the elastic blocking component and slide the sliding sleeve to a position misaligned with the connector slot, and then the connector can be pulled out of the connector slot, and the connector disassembly and assembly efficiency is high.

[0033] 3. The connector and connector slot used for connector positioning are covered by a sliding sleeve with a neat surface, which is not easy to stick to dust, making the surface of the entire connector smoother.

[0034] 4. When the female plug-in and the male plug-in are connected, a chamfered surface matching the positioning bevel is provided on the side surface of the positioning block. When there is no tension, the elastic force of the second spring conductive sheet body presses the front of the conductive block, and its force acts on the positioning bevel, which also pushes the connector to slide downward along the positioning bevel, achieving the initial self-locking of the connector slot and the connector. When tension is applied to both ends of the connector, the wedge-shaped structure formed by the positioning bevel and the chamfered surface pulls the connector downward, making it more difficult for the connector to loosen from the connector slot.

[0035] 5. After the sliding sleeve covers the connector slot, the second spring conductive sheet body is energized, and the exposed connector slot, the second spring conductive sheet body inside it is not energized, so it will not cause short circuit due to accidental touch, nor will it generate electric sparks when the connector is inserted into the connector slot, which can ensure the safety of the detection environment. Therefore, during detection, there is no need to frequently disconnect the main power switch, which improves the efficiency of detection.

[0036] 6. The sliding seat and the convex strip are used in conjunction with the elastic part. In addition to being a device for connecting the main circuit of the first spring conductive sheet and the second spring conductive sheet, it can also be used to position the sliding sleeve, combining the positioning and conductive mechanisms into one, simplifying the internal structure of the connector. The sliding seat and the elastic part are both inside the sliding sleeve, making the surface of the entire connector smoother and less prone to dust. There are no holes on the outside of the entire connector, and the sealing performance is more superior.

[0037] 7. A semi-cylinder is arranged on the sliding seat. On the one hand, it can reduce the friction between the sliding seat and the front slot, making the sliding seat slide more smoothly. On the other hand, the semi-cylinder can be used to separate the adjacent first spring conductive sheet body and the adjacent second spring conductive sheet body, further reducing the risk of short circuit.

[0038] 8. The sliding sleeve is an integrated structure. Except for the two end faces with sealing rings, there are no threaded holes or gaps in the other positions of the sliding sleeve. When waterproofing the circuit, only the two end faces of the sliding sleeve need to be considered, and the waterproof structure design of the connector is simpler.

[0039] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
