Description

Technical Field

[0001] This invention belongs to the field of electrical component technology, specifically relating to a structure for quick-release connectors, and more particularly to a quick-release connector for automotive wiring harnesses and its working method. Background Technology

[0002] Automotive wiring harness connectors typically use sealing rings to achieve a sealed connection between the male and female connectors.

[0003] In existing technologies, during long-term use, the sealing ring of the connector is prone to gelling, resulting in strong adhesion between the sealing ring and the surfaces of the male and female connectors. When the connector needs to be disassembled, the gelled sealing ring remains firmly attached between the mating surfaces of the male and female connectors, making them difficult to separate. Disassembly requires forcibly pulling the male and female connectors apart, which can easily tear the sealing ring, leaving residue in the female connector and preventing subsequent insertion of the male and female connectors.

[0004] Therefore, how to prevent the gelled sealing ring from remaining in the female connector and affecting the next insertion is a technical problem that urgently needs to be solved.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one quick-release connector for automotive wiring harnesses and its working method.

[0007] In a first aspect, embodiments of this disclosure provide a quick-release connector for automotive wiring harnesses, comprising:

[0008] Male and female heads;

[0009] The female head is equipped with a buckle;

[0010] The male head is equipped with a retaining plate;

[0013] The card plate is provided with a sliding groove for pushing the plate to insert;

[0014] One side of the sliding friction element abuts against the sealing ring, and the other side is in contact with the groove wall of the sliding groove;

[0015] When the push plate is pulled out of the sliding groove, it drives the sliding friction element to push the sealing ring, thereby loosening the sealing ring and facilitating the disassembly of the male and female connectors.

[0016] In one optional embodiment, the sliding friction element includes:

[0017] The first and second abutment plates are set opposite to each other;

[0018] Linkage rods, which are respectively connected to the first abutment plate and the second abutment plate;

[0019] The second abutting plate abuts against the sealing ring;

[0020] The first abutment plate is in contact with the wall of the sliding groove;

[0021] When the push plate is pulled out of the sliding groove, it drives the first abutment plate to move, thereby driving the second abutment plate to push the sealing ring.

[0022] In one optional embodiment, the contact surfaces of both the push plate and the first abutment plate are provided with a damping layer;

[0023] The contact surface between the second abutment plate and the sealing ring is provided with a damping layer.

[0024] In one optional embodiment, a pivot is provided at the connection between the connecting rod and the second abutment plate;

[0025] The rotating shaft passes through the connecting rod and is then embedded in the second abutment plate.

[0026] In one optional embodiment, the end of the card plate is further provided with a sliding hole for sliding the connecting rod;

[0027] The sliding hole is connected to the sliding groove;

[0028] The first abutment plate and the second abutment plate are respectively disposed on both sides of the sliding hole.

[0029] In one optional embodiment, a protective cover is also provided above the buckle;

[0030] The push plate is installed through the protective cover to complete the secondary locking.

[0031] In one optional embodiment, the buckle and the insertion end of the card plate are provided with inclined guide surfaces;

[0032] Furthermore, both the buckle and the plate are made of elastic material;

[0033] When the male connector is inserted into the female connector, the latch is inserted into the bottom of the plate until the protrusion on the plate engages with the latch.

[0034] In one alternative embodiment, the card is L-shaped;

[0035] Furthermore, the end of the card plate furthest from the buckle is fixedly connected to the male connector.

[0036] Secondly, this disclosure also provides a method of operation using the quick-release connector for automotive wiring harnesses as described above, comprising:

[0037] During insertion, the working method includes:

[0038] Insert the sealing ring into the female connector;

[0039] The male connector is inserted into the female connector to engage the locking plate with the buckle and to abut against the sliding sealing ring.

[0040] The push plate is inserted into the sliding slot of the card plate to complete the connection between the male and female connectors;

[0041] During disassembly, the working method includes:

[0042] Pull the push plate out of the sliding groove;

[0043] The sealing ring is loosened by pushing it with a moving friction element;

[0044] Separate the male and female connectors to complete the disassembly.

[0045] In one optional embodiment, the sliding friction element includes:

[0046] The first and second abutment plates are set opposite to each other;

[0047] Linkage rods, which are respectively connected to the first abutment plate and the second abutment plate;

[0048] The second abutting plate abuts against the sealing ring;

[0049] The first abutment plate is in contact with the wall of the sliding groove;

[0050] The step of pulling the push plate out of the sliding groove means that the push plate drives the first abutment plate to move, thereby driving the second abutment plate to push the sealing ring.

[0051] The beneficial effects of this invention are that the quick-release connector for automotive wiring harnesses and its working method actively push the sealing ring to loosen during disassembly through the sliding friction component, avoiding the gelled sealing ring from being stuck in the female connector due to strong adhesion, eliminating insertion obstacles caused by sealing ring residue, and ensuring that the sealing ring remains intact after disassembly, thus avoiding the impact of residue or deformation on the sealing performance of the next insertion, maintaining the waterproof and dustproof function of the wiring harness, and ensuring the reusable insertion and use of the male and female connectors.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0064] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0065] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0066] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise expressly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0067] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0068] Research has revealed that during long-term use, the sealing ring of the connector is prone to gelling, causing strong adhesion between the sealing ring and the surfaces of the male and female connectors. When disassembly is required, the gelled sealing ring remains firmly attached between the mating surfaces of the male and female connectors, making them difficult to separate. Disassembly requires forcibly pulling the male and female connectors apart, which can easily tear the sealing ring, leaving residue in the female connector and preventing subsequent mating.

[0069] Based on the above research, this disclosure provides a quick-release connector for automotive wiring harnesses and its working method. During disassembly, the sliding friction member 120 actively pushes the sealing ring to loosen, preventing the gelled sealing ring from being stuck in the female connector 200 due to strong adhesion. This eliminates insertion obstacles caused by sealing ring residue. After disassembly, the sealing ring remains intact, preventing residue or deformation from affecting the sealing performance of the next insertion. This maintains the waterproof and dustproof function of the wiring harness and ensures the reusable insertion and use of the male connector 100 and the female connector 200.

[0070] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0071] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0072] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0073] Please see Figure 1 and Figure 2At least one embodiment provides a quick-release connector for automotive wiring harnesses, including: a male connector 100 and a female connector 200; a buckle 210 is provided on the female connector 200; a retaining plate 110 is provided on the male connector 100; a sealing ring is provided on the abutting surface between the male connector 100 and the female connector 200; a sliding friction element 120 is provided at the abutting point between the buckle 210 and the sealing ring; the retaining plate 110 is provided with a sliding groove 111 for inserting a push plate 300; one side of the sliding friction element 120 abuts against the sealing ring, and the other side is in contact with the groove wall of the sliding groove 111; when the push plate 300 is pulled out from the sliding groove 111, it drives the sliding friction element 120 to push the sealing ring, thereby loosening the sealing ring and facilitating the disassembly of the male connector 100 and the female connector 200.

[0074] The sliding friction component 120 actively pushes the sealing ring to loosen during disassembly, preventing the gelled sealing ring from sticking to the female connector 200 due to strong adhesion. This eliminates insertion obstacles caused by sealing ring residue. After disassembly, the sealing ring remains intact, preventing residue or deformation from affecting the sealing performance of the next insertion. This maintains the waterproof and dustproof function of the wire harness and ensures the reusable insertion and use of the male connector 100 and the female connector 200.

[0075] Please see Figure 2 and Figure 3 The sliding friction member 120 includes: a first abutment plate 121 and a second abutment plate 122 disposed opposite to each other; a connecting rod 123 connected to the first abutment plate 121 and the second abutment plate 122 respectively; the second abutment plate 122 abutting against the sealing ring; the first abutment plate 121 fitting against the groove wall of the sliding groove 111; when the push plate 300 is pulled out from the sliding groove 111, it drives the first abutment plate 121 to move, thereby driving the second abutment plate 122 to push the sealing ring.

[0076] The linear motion of the push plate 300 is converted into the lateral thrust of the second abutment plate 122 by the connecting rod 123, so that the thrust is distributed to the second abutment plate, thereby avoiding the tearing caused by excessive local stress on the sealing ring due to the direct thrust of the push plate 300.

[0077] It should be noted that, in order to increase the transmission of the thrust of the push plate 300, a damping layer is provided on the contact surface of the push plate 300 and the first abutment plate 121; a damping layer is provided on the contact surface of the second abutment plate 122 and the sealing ring.

[0078] Please see Figure 2 and Figure 4 A pivot is provided at the connection between the connecting rod 123 and the second abutment plate 122; the pivot passes through the connecting rod 123 and is embedded in the second abutment plate 122.

[0079] To avoid interference when the second abutment plate 122 is inserted into the snap fastener 210, a pivot is provided at the connection of the second abutment plate 122 so that the second abutment plate 122 can be inserted into the snap fastener 210 along with the snap fastener 110. After the snap fastener 110 is fully inserted into the snap fastener 210, the upper part of the second abutment plate 122 abuts against the female head 200, thereby preventing the second abutment plate 122 from flipping over when it abuts against the sealing ring.

[0080] Please see Figure 3 and Figure 4 The end of the card plate 110 is also provided with a sliding hole 112 for sliding the connecting rod 123; the sliding hole 112 is connected to the sliding groove 111; the first abutment plate 121 and the second abutment plate 122 are respectively disposed on both sides of the sliding hole 112.

[0081] Please see Figure 2 and Figure 4 A protective cover 220 is also provided above the buckle 210; the push plate 300 is set through the protective cover 220 to complete the secondary locking. By setting the protective cover 220, external contaminants are prevented from entering the female connector 200. At the same time, the push plate 300 set through the protective cover 220 forms a secondary locking mechanism to prevent the connector from being accidentally pulled off.

[0082] Please see Figure 2 and Figure 4 The buckle 210 and the insertion end of the card plate 110 are provided with inclined guide surfaces; and the buckle 210 and the card plate 110 are both made of elastic material; when the male head 100 is inserted into the female head 200, the buckle 210 is inserted into the bottom of the card plate 110 until the protrusion of the card plate 110 engages with the buckle 210.

[0083] It should be noted that the card plate 110 is L-shaped; and the end of the card plate 110 away from the buckle 210 is fixedly connected to the male head 100.

[0084] At least one embodiment also provides a working method for using the quick-release connector for automotive wiring harnesses as described above. During disassembly, the sliding friction member 120 actively pushes the sealing ring to loosen, preventing the gelled sealing ring from being stuck in the female connector 200 due to strong adhesion. This eliminates insertion obstacles caused by sealing ring residue. After disassembly, the sealing ring remains intact, preventing residue or deformation from affecting the sealing performance of the next insertion. This maintains the waterproof and dustproof function of the wiring harness and ensures the reusable insertion and use of the male connector 100 and the female connector 200.

[0085] Specifically, please refer to Figure 5 During insertion, the working method includes:

[0086] S110: Insert the sealing ring into the female connector 200;

[0087] S120: The male head 100 is inserted into the female head 200 so that the card plate 110 engages with the buckle 210 and the sliding sealing ring abuts against the sealing ring;

[0088] S130: The push plate 300 is inserted into the sliding groove 111 of the card plate 110 to complete the connection between the male head 100 and the female head 200;

[0089] Please see Figure 6 During disassembly, the working method includes:

[0090] S210: Pull the push plate 300 out of the sliding groove 111;

[0091] S220: The sealing ring is loosened by pushing it with a dynamic friction element;

[0092] S230: Separate the male connector 100 from the female connector 200 to complete the disassembly.

[0093] Please see Figure 2 and Figure 3 The sliding friction member 120 includes: a first abutment plate 121 and a second abutment plate 122 disposed opposite to each other; a connecting rod 123 connected to the first abutment plate 121 and the second abutment plate 122 respectively; the second abutment plate 122 abutting against the sealing ring; the first abutment plate 121 fitting against the groove wall of the sliding groove 111; the step of pulling the push plate 300 out of the sliding groove 111, that is, the push plate 300 driving the first abutment plate 121 to move, thereby driving the second abutment plate 122 to push the sealing ring.

[0094] In summary, the present invention provides a quick-release connector for automotive wiring harnesses and its working method. The quick-release connector for automotive wiring harnesses includes: a male connector 100 and a female connector 200; a buckle 210 is provided on the female connector 200; a retaining plate 110 is provided on the male connector 100; a sealing ring is provided on the abutting surface between the male connector 100 and the female connector 200; a sliding friction element 120 is provided at the abutting point between the buckle 210 and the sealing ring; the retaining plate 110 is provided with a sliding groove 111 for inserting a push plate 300; one side of the sliding friction element 120 abuts against the sealing ring, and the other side is in contact with the groove wall of the sliding groove 111; when the push plate 300 is pulled out from the sliding groove 111, it drives the sliding friction element 120 to push the sealing ring, thereby loosening the sealing ring and facilitating the disassembly of the male connector 100 and the female connector 200. The sliding friction component 120 actively pushes the sealing ring to loosen during disassembly, preventing the gelled sealing ring from sticking to the female connector 200 due to strong adhesion. This eliminates insertion obstacles caused by sealing ring residue. After disassembly, the sealing ring remains intact, preventing residue or deformation from affecting the sealing performance of the next insertion. This maintains the waterproof and dustproof function of the wire harness and ensures the reusable insertion and use of the male connector 100 and the female connector 200.

[0095] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0096] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0097] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0098] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0099] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
