Description

Technical Field

[0001] This invention relates to the field of terminal block connectors, and more specifically to a connector cover fixing and snap-fit ​​structure. Background Technology

[0002] A connector cover, attached to the connector product body, allows the connector connection port to be opened or closed. In existing technology, the product body and cover are glued together, making them inseparable. (See reference...) Figure 1 , Figure 2 .

[0003] Problems and drawbacks of existing technology: uneven application of adhesive when fixing the cover to the body may cause the cover to fail to adhere properly and become unfixable to the product; fixing the cover to the body with adhesive is not conducive to assembly and results in high assembly costs. Summary of the Invention

[0004] The technical problem solved by this invention is that the cover of the connector is fixed to the body with glue, but the cover may fail to adhere properly, and the assembly cost of fixing the cover to the body with glue is high.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a connector with a cover fixing and fastening structure, comprising a product body and a cover, the cover comprising a connecting part and a fastening part, the fastening part being bendable relative to the connecting part, the fastening part being provided with a limiting rib and a buckle, the limiting rib engaging with one side of the product body, the buckle engaging with a step on the other side of the product body, a product body snap-fit ​​structure being provided on one side of the product body, and a cover snap-fit ​​structure being provided on the connecting part, the product body snap-fit ​​structure and the cover snap-fit ​​structure being fixedly connected by snap-fit.

[0006] Pressing the cover causes the connection between the connecting part and the fastening part to deform under force, further limiting the position of the limiting rib and the product body. At the same time, the buckle is fastened to the step on one side of the product body, and the cover and the body are in a fastened state.

[0007] When you want to open the lid, you need to move the latch to separate it from the main body. The connection between the connecting part and the latching part will spring back, and the lid and the main body will be in the open state.

[0008] Alternatively, the product body's snap-fit ​​structure is a groove-shaped structure that is narrower at the top and wider at the bottom, with a step formed between the narrow and wide portions. The lid's snap-fit ​​structure consists of a pair of oppositely positioned hooks that insert into the groove-shaped structure from top to bottom, engaging with the step. When the lid's hooks are subjected to force and deform, they insert into the groove-shaped structure of the product body. The hooks then spring back and engage with the step of the groove-shaped structure, securing the lid and product body together.

[0009] Alternatively, the product body snap-fit ​​structure is a body rib protruding outward on one side of the product body, and the cover snap-fit ​​structure is a cover groove, with the body rib and the cover groove engaging.

[0010] As an improvement, the main body rib is deformed by the heat-melting fixture and then pressed, and the cover snap-fit ​​structure is restricted to the main body rib.

[0011] A bend is provided between the connecting part and the fastening part, which facilitates the fastening part to bend relative to the connecting part and also facilitates the fastening part to spring back when the lid is opened.

[0012] One side of the product body has a recessed structure with an inclined top surface, and the limiting rib is fitted into the recessed structure.

[0013] The present invention has the following technical effects:

[0014] First, the lid is no longer fixed to the product body by applying glue. Instead, the product is made easier to assemble and produce by optimizing the lid structure and assembly process, avoiding quality problems caused by uneven glue application, and further improving production efficiency.

[0015] Secondly, the lid and the product body are fused together by the hot-melt ribs of the body and the groove of the lid, so that the lid and the product body are locked and fixed, eliminating the quality problems caused by the product gluing process that cause the lid to fail to fix, and improving production efficiency.

[0034] First Embodiment

[0035] like Figure 3 , Figure 5 , Figure 7 , Figure 8 A connector with a cover fixing and fastening structure includes a product body 10 and a cover 20. The cover includes a connecting part 21 and a fastening part 22. The fastening part can be bent relative to the connecting part. The fastening part is provided with a limiting rib 23 and a snap fastener 24. The limiting rib is engaged with one side of the product body, and the snap fastener is engaged with a step on the other side of the product body. One side of the product body is provided with a product body snap-fit ​​structure, and the connecting part is provided with a cover snap-fit ​​structure. The product body snap-fit ​​structure and the cover snap-fit ​​structure are fixedly connected by snap-fit.

[0036] like Figure 5The product body snap-fit ​​structure is a groove-shaped structure 11 that is narrow at the top and wide at the bottom. A step is formed between the narrow part and the wide part of the groove-shaped structure. The cover snap-fit ​​structure is a pair of hooks 25 arranged opposite to each other. The pair of hooks are inserted into the groove-shaped structure from top to bottom, and the hooks cooperate with the step.

[0037] like Figure 3 A bending arc 27 is provided between the connecting part 21 and the fastening part 22, which facilitates the fastening part to bend relative to the connecting part and also facilitates the fastening part to spring back when the cover is opened.

[0038] like Figure 3 The product body 10 has a recessed structure 13 on one side, the top surface of the recessed structure is inclined, and the limiting rib 23 is fitted in the recessed structure.

[0039] refer to Figure 7 , Figure 8 During installation, the hook 25 of the cover deforms under force and inserts into the groove structure 11 of the product body. The hook 25 rebounds and engages with the step of the groove structure, so that the cover 20 and the product body 10 are in a fastened state.

[0040] When in use, pressing the cover 20 causes the bending arc 27 between the connecting part 21 and the fastening part 22 to deform under force, further limiting the positioning rib 23 and the product body 10. At the same time, the buckle 24 fastens to the step on one side of the product body 10, and the cover 20 and the product body 10 are in a fastened state.

[0041] When the lid 20 needs to be opened, the buckle 24 needs to be moved to separate from the product body 10. The bending arc 27 of the connecting part 21 and the fastening part 22 will spring back, and the lid and the body will be in the open state.

The fastening part can be bent relative to the connecting part. The fastening part is provided with a limiting rib 23 and a snap fastener 24. The limiting rib is engaged with one side of the product body, and the snap fastener is engaged with a step on the other side of the product body. One side of the product body is provided with a product body snap-fit ​​structure, and the connecting part is provided with a cover snap-fit ​​structure. The product body snap-fit ​​structure and the cover snap-fit ​​structure are fixedly connected by snap-fit.

[0044] The product body snap-fit ​​structure is a body rib 12 protruding outward on one side of the product body, and the cover snap-fit ​​structure is a cover groove 26, with the body rib and the cover groove cooperating.

[0045] After the main body rib 12 is deformed by the heating fixture, it is pressed tightly, and the cover snap-fit ​​structure is restricted on the main body rib.

[0046] like Figure 9 A bending arc 27 is provided between the connecting part 21 and the fastening part 22, which facilitates the fastening part to bend relative to the connecting part and also facilitates the fastening part to spring back when the cover is opened.

[0047] like Figure 9 The product body 10 has a recessed structure 13 on one side, the top surface of the recessed structure is inclined, and the limiting rib 23 is fitted in the recessed structure.

[0048] refer to Figure 9 , Figure 10 During installation, the cover groove 26 is aligned and assembled with the body rib 12. The body rib 12 is further heated and deformed by a machine heating fixture, and then further pressed to fuse the body rib 12 with the cover groove 26, so that the cover 20 and the product body 10 are in a fixed and locked state.

[0049] like Figure 12 , Figure 13 When in use, pressing the cover 20 causes the bending arc 27 between the connecting part 21 and the fastening part 22 to deform under force, further limiting the positioning rib 23 and the product body 10. At the same time, the buckle 24 fastens to the step on one side of the product body 10, and the cover 20 and the product body 10 are in a fastened state.

[0050] When the lid 20 needs to be opened, the buckle 24 needs to be moved to separate from the product body 10. The bending arc 27 of the connecting part 21 and the fastening part 22 will spring back, and the lid and the body will be in the open state.

[0051] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
