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 the two 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 structure used to connect the male and female ends needs to be exposed, lacks protection, and is 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, which is easy to adhere to dust and dirt.

[0003] On the other hand, in existing automotive connectors, because the conductive plates used for the male and female plugs are directly connected to the wires, electric sparks are easily generated when the connector electrodes touch for a moment, causing a fire hazard; therefore, when the vehicle is inspected and repaired, the vehicle needs to be powered off every time the connector is disassembled, which brings inconvenience to the vehicle inspection and maintenance.

[0055] The present invention will be further described below with reference to the accompanying drawings.

[0056] like Figures 1 to 17As shown, the present invention describes a vehicle-grade waterproof connector structure, which includes a female plug-in and a male plug-in; the female plug-in includes a connecting seat 6; the connecting seat 6 is connected to a first rubber-coated head 1; 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 one 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 connection position between the connector 302 and the connector slot 601 and is 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;

[0057] After one end of the first rubber-wrapped head 1 is inserted into the positioning groove 608 provided on the connecting seat 6, the first rubber-wrapped head 1 and the connecting seat 6 are connected as one body by screws; the joint 302 and the second rubber-wrapped head 3 are formed as one body;

[0058] The connection between the female and male plugs is achieved by inserting the connector 302 from the side surface of the connection base 6 into the connector slot 601 for positioning. When the female and male plugs are pulled, the insertion direction of the connector 302 into the connector slot 601 is perpendicular to the pulling direction of the female and male plugs. Therefore, even after being pulled, the connector 302 will not be pulled out in the direction of insertion into the connector slot 601. The structure of the male and female plugs themselves serves as the positioning structure for the connection. Finally, the sliding sleeve 2 seals the end surface of the connector slot 601, further preventing the connector 302 from being pulled out laterally from the connector slot 601.

[0059] When the connector is pulled, the sliding sleeve 2 is not subjected to any 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.

[0060] As a preferred embodiment of the present invention, a clamping 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 clamping 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; and a chamfered surface 302a1 is provided on the side surface of the positioning block 302a that matches the positioning inclined surface 601a1.

[0061] The angle between the positioning inclined surface 601a1 and the bottom surface of the connector slot 601 is an acute angle;

[0062] When the number of the clamping blocks 601a and the number of the positioning blocks 302a are one, the connector clamping slot 601 and the connector 302 are both in an "L" shape;

[0063] There can be two clamping blocks 601a, symmetrically arranged on both sides. There can also be two positioning blocks 302a, symmetrically arranged. Thus, both the connector slot 601 and the connector 302 are T-shaped. The clamping blocks 601a form a corner slot for the connector slot 601, and the positioning blocks 302a are fastened to the clamping blocks 601a to position the connector. This prevents the connector 302 from coming loose from the connector slot 601 when tension is applied to the connector. The side surfaces of the positioning blocks 302a are provided with chamfered surfaces 302a1 that match the positioning bevels 601a1. When no tension is applied, the elastic force of the second spring conductive sheet body 9 presses against the front of the conductive block 303. This force acts on the positioning bevels 601a1, pushing the connector 302 downward along the positioning bevels 601a1, achieving a preliminary self-locking effect between 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 .

[0064] As a preferred embodiment of the present invention, a connecting groove 606 is provided on the side of the connecting seat 6 away from the connector slot 601; the second spring conductive sheet body 9 is provided in the connecting groove 606; the inner bottom wall of the connecting groove 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 piece 7 is fixed inside; the end of the first spring conductive piece 7 extends into the front slot 605; a sliding seat 8 is slidably connected to the front slot 605; one end of the first spring conductive piece 7 extending into the front slot 605 and one end of the second spring conductive piece body 9 extending into the front slot 605 are respectively arranged on both sides of the sliding seat 8; the sliding sleeve 2 is provided with a push-pull assembly for pulling the sliding seat 8 to perform a lifting movement in the front slot 605; the sliding seat 8 is provided with conductive posts 801 that pass through both end surfaces of the sliding seat 8;

[0065] When the connector is in normal use, the sliding sleeve 2 is positioned outside the connection between the connector 302 and the connector slot 601. The sliding sleeve 2 pushes the sliding seat 8 to slide within the front slot 605, causing the conductive post 801 to connect the first spring conductive piece 7 with one end of the first spring conductive piece 7 inserted into the front slot 605 and the second spring conductive piece body 9 with one end of the second spring conductive piece body 9 inserted into the front slot 605. When the sliding sleeve 2 is pulled out to a position misaligned with the connector slot 601, exposing the connector slot 601, the sliding sleeve 2 pushes the sliding seat 8 to slide within the front slot 605, causing the first spring conductive piece 7 to extend into the front slot 605 and the second spring conductive piece body 9 to extend into the front slot 605 to be misaligned with the conductive post 801. The exposed second spring conductive piece body 9 is disconnected from the first spring conductive piece 7 connected to the power source.

[0066] Therefore, the exposed connector slot 601 and the second spring conductive plate body 9 inside it are not energized, thus preventing accidental short circuits and sparks from being generated when the connector 302 is inserted into the connector slot 601. This ensures a safe testing environment. Therefore, during testing, there is no need to frequently turn off the main power switch, improving testing efficiency.

[0067] As a preferred embodiment of the present invention, the first spring conductive sheet 7 is provided with an elastic portion 702 at one end thereof that extends into the front slot 605; the push-pull assembly is a ridge 202 provided on the inner side wall of the sliding sleeve 2; the ridge 202 extends into the connecting groove 606; the surface of the ridge 202 and the end of the elastic portion 702 respectively press against the upper and lower ends of the sliding seat 8; the ridge 202 is provided with a boss surface 202a; a transition slope 202c is provided between the surface of the ridge 202 and the boss surface 202a; the elastic portion 702 is formed by bending the end of the first spring conductive sheet 7;

[0068] The main body of the sliding seat 8 is made of a non-conductive material; the connecting seat 6 is provided with a protrusion groove 604 for passing the protrusion 202. Under the action of the elastic portion 702, the sliding seat 8 is pressed against the surface of the protrusion 202. When the sliding sleeve 2 is positioned externally to the connection between the connector 302 and the connector slot 601, the boss surface 202a partially contacts the sliding seat 8, and the conductive post 801 on the sliding seat 8 connects the first spring conductive piece 7 and the second spring conductive piece body 9. However, after the sliding sleeve 2 slides to a position displaced from the connector slot 601, the sliding seat 8 aligns with the lower portion of the protrusion 202. The sliding seat 8 is pushed downward by the elastic portion 702, causing the conductive post 801 to be displaced from both the conductive position of the first spring conductive piece 7 and the conductive position of the second spring conductive piece body 9, thereby disconnecting the first spring conductive piece 7 from the second spring conductive piece body 9.

[0069] The structure for pushing the sliding seat 8 is completely arranged inside the sliding sleeve 2, which improves its waterproof performance and makes the surface of the entire connector smoother and less prone to dust. In addition, the second spring conductive piece body 9 can be immediately de-energized after the sliding sleeve 2 is pulled out and misaligned with the connector slot 601; and the second spring conductive piece body 9 can be immediately energized after the connector slot 601 is aligned with the sliding sleeve 2, making it safer to use. The sliding seat 8 and the conductive column 801 are combined using an insert injection molding process.

[0070] The elastic portion 702 for providing elastic force to the sliding seat 8 is directly formed by bending the original structure of the first spring conductive piece 7, which simplifies the entire structure and improves the installation efficiency of the connector.

[0071] As a preferred embodiment of the present invention, the sliding seat 8 is the elastic blocking component;

[0072] The bottom surface of the sliding seat 8 is arc-shaped; the top surface of the boss 202a is provided with an arc-shaped positioning recess 202b. When the sliding sleeve 2 slides to the outer position where it is connected to the connector 302 and the connector slot 601, the bottom of the sliding seat 8 is pressed into the arc-shaped positioning recess 202b by the elastic force of the elastic portion 702, preventing the sliding sleeve 2 from sliding relative to the connector 6. When the sliding sleeve 2 needs to be pulled, a certain amount of thrust is required to push the sliding sleeve 2, causing the sliding seat 8, with its arc-shaped bottom surface, to slide along the inclined surface of the arc-shaped positioning recess 202b. The inclined surface of the arc-shaped positioning recess 202b squeezes the bottom of the sliding seat 8, compressing the elastic portion 702 and causing the sliding seat 8 to first disengage from the arc-shaped positioning recess 202b. Using the sliding seat 8 as an elastic barrier component, the sliding seat 8 serves both to connect the circuit and to position the sliding sleeve 2.

[0073] 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 pillars 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;

[0074] The sliding of the sliding seat 8 and the front slot 605 can be achieved by providing 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 bodies 7 and the adjacent second spring conductive sheet bodies 9, further reducing the risk of short circuit.

[0075] As a preferred embodiment of the present invention, the first spring conductive piece body 7 and the second spring conductive piece body 9 are both in a "U" shape;

[0076] The second spring conductive piece body 9 extends into the rear slot 603 and is provided with a second spring conductive piece 901 at one end; the second spring conductive piece body 9 extends into the front slot 605 and is provided with a third spring conductive piece 902 at one end; the first spring conductive piece body 7 extends into the front slot 605 and is provided with a first spring conductive piece 701 at one end; the other end of the first spring conductive piece 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 piece 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 an 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 an insert injection molding process; the first rubber bag head 1 and the second rubber bag head 3 are both formed by injection molding;

[0077] The wire connecting sleeve 703, the first spring conductive sheet 701 and the elastic portion 702 are integrally bent from a single conductive sheet, and the second spring conductive sheet 901 and the third spring conductive sheet 902 are integrally bent from a single conductive sheet, making the processing of the conductive structure simpler.

[0078] As a preferred embodiment of the present invention, a second retaining ring 301 is provided on the second lagging 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 lagging head 3; a first positioning column 101 is provided on the first lagging 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 lagging head 1; and the sliding sleeve 2 presses the first sealing ring 4 onto the second retaining ring 301;

[0079] 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;

[0080] The second sealing ring 5 is used to seal the gap between the first rubber-coated 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;

[0081] 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. In addition, the sliding sleeve 2 is an integrated structure. Except for the two end faces with sealing rings, the other positions of the sliding sleeve 2 have no 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.

[0082] 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 side 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; a clamping column 602a is provided on both sides of the straight groove 602; a ring is provided at both ends of the silicone rubber band 10; the rings at both ends are respectively inserted into the clamping column 602a and fixed;

[0083] 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, to facilitate assembly, a straight groove 602 passes through the end face close to the second rubber coating head 3, so that a 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 detached after being buckled on the hook 204 for the first time. During future use, 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 coating head 3; in addition, to simplify the mold structure for molding the sliding sleeve 2, a process hole 203a is provided on the second rubber coating head 3, which is opposite to the hook 204, so that the molding of the hook 204 is simpler; and a sealing block 501 is provided on the second sealing ring 5 for sealing the process hole 203a.

[0084] As a preferred embodiment of the present invention, a plurality of handle holes 201 are provided on the surface of the sliding sleeve 2 .

[0085] The beneficial effects of the present invention are:

[0086] 1. The connection structure of the female plug-in and the male plug-in is composed of a connector with a "T" or "L" shape in cross section, which is 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.

[0087] 2. When disassembling the female plug-in and the male plug-in, 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, which makes the connector disassembly and assembly efficiency high.

[0088] 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.

[0089] 4. When the female and male connectors are connected, the side surfaces of the positioning block are provided with chamfered surfaces that match the positioning bevels. When not under tension, the elastic force of the second spring conductive plate compresses the front of the conductive block. This force acts on the positioning bevels, pushing the connector downward along the positioning bevels, achieving a preliminary self-locking of the connector slot and connector. When tension is applied to both ends of the connector, the wedge-shaped structure formed by the positioning bevels and chamfers pulls the connector downward, making it more difficult for the connector to loosen from the connector slot.

[0090] 5. After the sliding sleeve covers the connector slot, the second spring conductive piece is energized. The exposed connector slot, and the second spring conductive piece inside, is not energized. This prevents accidental short circuits and sparks from the moment the connector is inserted into the slot, ensuring a safe testing environment. Therefore, during testing, there is no need to frequently disconnect the main power switch, improving testing efficiency.

[0091] 6. The sliding seat, rib, and elastic portion work in conjunction, not only as a device for connecting the main circuits of the first and second spring conductive plates, but also for positioning the sliding sleeve, combining the positioning and conductive mechanisms into one, simplifying the connector's internal structure. Furthermore, the sliding seat and elastic portion are both located inside the sliding sleeve, resulting in a smoother, dust-resistant surface. The connector also has no external holes, resulting in superior sealing performance.

[0092] 7. A semi-cylinder is provided 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 piece body and the adjacent second spring conductive piece body, further reducing the risk of short circuit.

[0093] 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 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.

[0094] The above description is only a preferred embodiment of the present invention. Therefore, any 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.
