Description

A snap-fit ​​connector for easy fitting into a slotted hole Technical Field

[0001] This utility model relates to the field of connector clips, and in particular to a clip that facilitates the snapping of connectors into oblong holes. Background Technology

[0002] In modern electronic equipment, home appliances, and industrial control, various board-to-board and board-to-wire connectors are widely used. To secure these connectors or components, mounting holes are often designed on plastic housings, mounting plates, and brackets. Among them, oblong holes (also known as racetrack holes) are widely used in precision assembly applications due to their unique advantages of adjusting the mounting position and allowing for minor assembly errors.

[0003] Traditional snap-fit ​​structures used for snap-fit ​​connections mostly feature a round, protruding head. When such round snap-fits are used with oblong holes, there are obvious compatibility defects: due to the significant difference in length and width of the oblong hole, the round head is prone to wobbling or misalignment along its long axis, resulting in insufficient connection stability. Furthermore, when precise snap-fit ​​is required, repeated adjustments to the angles are necessary, making it difficult to achieve a quick and accurate one-time "click" connection, leading to low assembly efficiency. This is especially true in blind operations or confined spaces, where the operational difficulty is further increased. Summary of the Invention

[0004] In order to solve the technical problems mentioned in the background art, the present invention adopts the following technical solution:

[0005] A snap fastener for facilitating the fitting of a connector to an oblong hole includes a snap fastener body that snaps into the oblong hole, the snap fastener body being connected to a connector body on its outer side, the snap fastener body including a snap fastener seat fixedly connected to the connector body, elastic blocks being symmetrically fixedly connected to both sides of the snap fastener seat, and multiple sets of slots being provided at the ends of the elastic blocks, the slots snapping into the edge of the oblong hole.

[0006] Preferably, the multiple sets of card slots are arranged in a stepped manner.

[0007] Preferably, the outer surface of the elastic block is designed with an inclined surface structure.

[0008] Preferably, the elastic block is made of elastic plastic material, and a weight-reducing groove is provided through the inner cavity of the buckle seat.

[0009] Preferably, guide grooves are provided on both sides and the top of the connector body, a slot is provided horizontally through the center of the connector body, and a limit groove is provided vertically through one end of the connector body.

[0010] Preferably, a support cover is fixedly connected to the outside of the connector body, and a rubber pad is provided at the outer edge of the support cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects;

[0012] The snap-fit ​​connector designed in this utility model adopts a "square" design for its snap-fit ​​buckle, and symmetrical elastic blocks are set on the outside of the "square" snap-fit ​​buckle. After the elastic blocks are used to squeeze through the waist-shaped hole, the stepped snap-fit ​​groove is used to snap-fit ​​with the outside of the waist-shaped hole to achieve assembly. It can adapt to waist-shaped holes of different widths and effectively ensures a stable and reliable gapless connection between the two, while improving the convenience and efficiency of assembly operations, thereby indirectly ensuring the overall structural strength and production efficiency.

[0019] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Referring to Figures 1-4, a snap fastener for facilitating the fitting of a connector with an oblong hole is illustrated in this utility model.

[0023] Referring to Figures 1 and 4, the buckle of this utility model that facilitates the snap-fit ​​of the connector to fit the waist-shaped hole includes a buckle body that snaps into the waist-shaped hole 4 and a connector body 2.

[0024] As shown in Figure 1, the outer side of the buckle body is connected to the connector body 2, and the buckle body includes a buckle seat 1 that is fixedly connected to the connector body 2.

[0025] As shown in Figure 2, guide grooves 201 are provided on both sides and the top of the connector body 2. A slot 202 is provided horizontally through the center of the connector body 2. A limiting groove 203 is provided vertically through one end of the connector body 2. During the installation with other matching connectors, the matching connector has a pin that can be inserted into the slot 202 and a guide block that slides into the guide groove 201. The matching connecting cavity has a locking pin that slides into the limiting groove 203 on the outside, which facilitates the assembly between the connectors.

[0026] As shown in Figure 3, a support cover 3 is fixedly connected to the outside of the connector body 2. A rubber pad 301 is provided at the outer edge of the support cover 3. The support cover 3 can abut against the designated position after the buckle body is connected. It can be engaged with the slot 102 to provide an auxiliary reinforcement effect. The support cover 3 has a certain degree of flexibility and can be squeezed and tilted to deform. At the same time, the rubber pad 301 on the outer wall of the support cover 3 can provide an auxiliary friction stabilization effect.

[0027] Elastic blocks 101 are symmetrically fixedly connected on both sides of the buckle seat 1. The outer side of the elastic block 101 is designed with an inclined surface 103. Multiple sets of slots 102 are provided at the end of the elastic block 101. The slots 102 are engaged with the edge of the waist-shaped hole 4. The multiple sets of slots 102 are arranged in a stepped shape.

[0028] Among them, the elastic block 101 is made of elastic plastic material. During the process of inserting the buckle body into the waist-shaped hole 4, the elastic block 101 can be squeezed to reduce the volume of the buckle body, making it easier to insert. Secondly, the buckle seat 1 has a weight reduction groove 104 through the inner cavity to reduce the overall weight and cost.

[0029] Based on the above structural configuration, when using this device, the operator connects and fixes the adjacent snap-fit ​​connectors through the connector body 2, then aligns the snap-fit ​​body with the outside of the waist-shaped hole 4, and squeezes the elastic blocks 101 on both sides of the snap-fit ​​seat 1 to bring them closer to the center. Then, the inclined surface 103 on the outside of the elastic block 101 aligns with the waist-shaped hole 4 for snap-fit. As it is gradually snapped in, the inclined surface 103 contacts the inner wall of the waist-shaped hole 4 and automatically squeezes the elastic block 101 until the elastic block 101 is completely snapped into the waist-shaped hole 4, thus completing the snap-fit ​​of the snap-fit ​​body.

[0030] Furthermore, the buckle seat 1 and the elastic blocks 101 on both sides are arranged in a "square" shape, which can effectively fit the waist-shaped hole 4. Moreover, after the snap-fit ​​is completed, as shown in Figure 3, the snap-fit ​​groove 102 on the outer side of the elastic block 101 can snap into the edge of the waist-shaped hole 4 to achieve a stable fit, and the elastic support of the elastic block 101 maintains a seamless snap-fit.

[0031] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 this utility model.
