Description

Technical Field

[0001] This utility model relates to the field of automotive lighting components technology, specifically to a secondary locking fastener assembly for preventing connectors from loosening. Background Technology

[0002] Wiring harnesses and other connectors (or plugs) on vehicle lights are typically secured to the light bracket with clips. While this method is simple and quick, it carries the risk of loosening due to vibrations and other factors. To avoid these problems, some engineers have improved the connector structure, designing connectors with a secondary locking mechanism. However, these connectors often suffer from drawbacks such as higher cost, higher price, and inconvenient operation, and due to limited model options, they cannot meet the needs of most applications.

[0003] Based on the above situation, our technical staff has developed a secondary locking buckle assembly for preventing connectors from loosening. This assembly has many advantages such as simple structure, easy use, and low cost. Utility Model Content

[0004] The main objective of this invention is to address the risk of connector detachment in existing technologies by providing a simple and easy-to-use secondary locking fastener assembly. This assembly mainly includes a secondary locking fastener 1, a bracket 2, and a connector 3. The secondary locking fastener 1 comprises a tongue-shaped fastener 1-1 and a baffle 1-2, with their tops connected to form a U-shaped structure. A socket is provided on the bracket 2. After the secondary locking fastener 1 is inserted into the socket of the bracket 2, it locks in place. The baffle 1-2 passes through the socket and abuts against the tail of the connector 3, thus preventing the connector 3 from detaching. This assembly utilizes the tongue-shaped fastener 1-1 to achieve quick assembly and disassembly of the secondary locking fastener 1 and the bracket 2, and uses the baffle 1-2 to prevent the connector 3 from falling off or being improperly inserted.

[0005] In the above scheme, the secondary lock fixing buckle 1 also includes a handle 1-5. The tongue-shaped buckle 1-1 and the baffle 1-2 are both fixed to the end of the handle 1-5 on the same side and are arranged in a U-shape.

[0006] In the above design, grooves are also provided on the handles 1-5. The grooves mainly serve to reduce weight, enhance strength, and facilitate gripping.

[0007] In the above scheme, the length of the tongue-shaped buckle 1-1 is less than the length of the baffle 1-2. Only when the baffle 1-2 is long enough can it extend to and abut against the tail of the connector 3, preventing it from coming out backward or being improperly inserted.

[0008] In the above solution, the tongue-shaped buckle 1-1 is provided with a slot or a buckle protrusion, and a matching buckle protrusion or slot is provided in the insertion hole of the bracket 2. Through the mutual cooperation of the slot and the buckle protrusion, it is convenient to quickly assemble and disassemble the secondary locking buckle 1 and the bracket 2.

[0009] In the above scheme, reinforcing ribs 1-5 are provided along the length of the front and rear surfaces of the baffle 1-2. The reinforcing ribs can improve the strength of the baffle and prevent it from breaking and failing when squeezed by the connector 3.

[0010] In the above design, the ends of baffles 1-2 have a trapezoidal or rounded transition. This transition design at the ends of baffles 1-2 can prevent scratches or cuts to the wire harness or connectors.

[0011] In the above scheme, the socket on bracket 2 is H-shaped. The H-shaped socket matches the inverted U-shaped secondary locking buckle, and after being inserted, it can limit and fix the secondary locking buckle.

[0012] In the above solution, a slot is provided at the tail of the connector 3, and the baffle 1-2 is inserted into the slot to effectively prevent the connector 3 from falling off or being improperly inserted.

[0013] The secondary locking buckle assembly provided by this utility model has advantages such as simple structure, reusability, and good performance, completely avoiding problems such as improper insertion or detachment of connectors. The entire secondary locking buckle is injection molded from engineering plastics, effectively reducing production and usage costs, and can be inserted and removed with one hand, making it very convenient to operate. In addition, the secondary locking buckle is small in size, does not compress the internal space of the lamp body, and does not affect the arrangement of internal parts. It can be used with most connectors on the market and can be used in automotive, electronic, and mechanical parts or equipment containing connectors, effectively ensuring the reliability of connector connections.

[0020] To enable those skilled in the art to fully understand the technical solution and beneficial effects of this utility model, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be emphasized that these embodiments and drawings are merely some implementations of this utility model. Besides these, this utility model can have many other implementations, and any simple improvements or substitutions based on these embodiments will fall within the protection scope of this utility model.

[0021] like Figure 5 As shown in this application, in the prior art, connector 3 was directly and horizontally plugged into a component with a connector (such as a vehicle headlight), and the wiring harness at the end of connector 3 was fixed to the side wall of bracket 2 by a wiring harness clip. In this installation state, irregular vibrations generated during vehicle operation may cause connector 3 to loosen or fall off, posing certain risks and hidden dangers.

[0022] Therefore, we developed a product such as Figure 1-2 The secondary locking buckle shown eliminates the risk of connector 3 becoming loose. This secondary locking buckle comprises an integrally formed upper and lower half. The upper half is a handle 1-5 with a groove, and the lower half includes a tongue-shaped buckle 1-1 and a baffle 1-2 positioned at a certain distance from each other, with the baffle 1-2 being longer than the tongue-shaped buckle 1-1. The tongue-shaped buckle 1-1 and the baffle 1-2 form an inverted U-shaped structure.

[0023] In some other embodiments, in addition to being arranged side by side, the tongue-shaped buckle 1-1 and the baffle 1-2 can also be arranged side by side, left and right or up and down, or even arranged side by side on the same plane. All these layouts can achieve the same effect.

[0024] The tongue-shaped buckle 1-1 has a slot 1-3, and the bracket 2 has a matching insertion hole and buckle protrusion. The secondary locking buckle 1 and the bracket 2 are fixedly connected through the slot and buckle protrusion, which facilitates quick assembly and disassembly. Alternatively, the tongue-shaped buckle 1-1 can have a buckle protrusion, and the bracket 2 can have a matching insertion hole and slot, with assembly and disassembly still achieved through the slot and buckle protrusion.

[0025] Considering that the baffle 1-2 is relatively slender, multiple reinforcing ribs 1-4 are provided along its length on one or both sides of the baffle 1-2 (i.e., the front and back sides) to enhance its strength. To prevent the baffle 1-2 from scratching the connector 3 or the wire harness, its ends are designed with rounded corners.

[0026] The secondary lock fixing buckle is used in conjunction with bracket 2 and connector 3. Specific usage instructions are as follows: Figure 3-5 As shown, specifically: a U-shaped socket is provided on the original bracket 2, and a buckle protrusion is provided on the inner wall of one side of the socket. The secondary locking buckle is vertically inserted into the U-shaped socket of the bracket 2, and the buckle protrusion engages with the slot 1-3 of the tongue-shaped buckle 1-1 to secure it. At the same time, the baffle 1-2 of the secondary locking buckle passes through the U-shaped socket and extends downward, with the end of the baffle 1-2 abutting against the tail of the connector 3 to prevent it from moving to the left and loosening. When it is necessary to remove the connector 3, simply pull the secondary locking buckle upward, causing the baffle 1-2 to rise away from the connector 3.

[0027] In some embodiments, a slot can be provided at the tail of connector 3, and the baffle 1-2 can be vertically inserted into the slot to achieve a better anti-loosening effect.

[0028] The secondary lock fixing buckle can be as follows: Figure 5 As shown, it can be installed vertically, or it can be installed horizontally or at an angle, depending on the assembly orientation and angle of the connector.

[0029] The secondary locking buckle provided by this utility model has the advantages of simple structure, small size and low cost. It will not compress the internal space of the lamp body, nor will it affect the arrangement of internal parts of the lamp body. It not only occupies little space but is also simple and convenient to install. It can ensure a stable and reliable connection of the connector and prevent it from falling off during use.
