Abstract
Description
Technical Field
[0001] This utility model relates to the field of KEY bit structure technology, and in particular to a protrusion component, KEY bit structure and connector of a KEY bit structure. Background Technology
[0002] like Figure 1 As shown, the KEY structure includes a protrusion 6 and a groove 7. KEY structures are commonly found on connectors in various electronic products, providing the connector with a foolproof insertion direction identification function. The protrusion 6 in common KEY structures is made of plastic and is integral with the connector's plastic shell. It can be directly injection molded in one piece without additional manufacturing processes. However, the plastic protrusion 6 is relatively weak and easily wears down, leading to cracking and the generation of plastic debris. The generation of plastic debris can compromise the contact stability of the connector, causing it to lose its functional application. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address at least one defect of the related technologies mentioned in the background: the plastic protrusion of the KEY position structure is weak and easily worn. This utility model provides a protrusion component of the KEY position structure, a KEY position structure and a connector.
[0004] The technical solution adopted by this utility model to solve its technical problem is: to construct a KEY position structure protrusion component, including two spaced slots, a protrusion body and a cover made of hard material;
[0005] In the depth direction of the card slot, one side and one end of the card slot are provided with openings, wherein the openings on one side of the two card slots face each other, and the openings at one end of the two card slots face the same direction.
[0006] The protruding body spans one side of the openings on the two slots, and the protruding body and the slots are integrally formed.
[0007] On the cross-section of the side of the slot with an opening, there is a gap between the slot and the two sides of the protruding body;

[0035] like Figure 2 As shown, some embodiments of this utility model disclose a protruding component for a KEY position structure, including two spaced slots 1, a protruding body 2, and a cover 3 made of a rigid material, as detailed below:
[0036] In the depth direction D of the card slot 1, adjacent sides 11 and ends 12 of the card slot 1 are open, wherein the openings of the sides 11 of the two card slots 1 face each other, and the openings of the ends 12 of the two card slots 1 face the same direction, that is... Figure 2 The openings on one side 11 of the two slots 1 shown are both facing inward, and the openings on one end 12 of the two slots 1 are both facing upward.
[0037] like Figure 2 As shown, the protruding body 2 spans one side 11 of the openings on the two slots 1, and the protruding body 2 and the slots 1 are integrally formed.
[0038] like Figure 3 As shown, on the cross-section of the side 11 of the slot 1 with an opening, there is a gap 4 between the slot 1 and the two sides 22 of the protruding body 2.
[0039] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the cover 3 is inserted into the gap 4 from one end 12 of the slot 1 and fixed on the slot 1 to cover the end face 21 and two sides 22 of the protruding body 2.
[0040] This embodiment effectively solves the problem of weak strength and easy wear of the plastic protrusion of the KEY position structure by covering the end face 21 and the two sides 22 of the protruding body 2 of the KEY position structure with a cover 3 made of hard material.
[0041] In some embodiments, the slot 1 and the protruding body 2 are both plastic bodies, such as polyethylene. Polyethylene is just an example and is not intended to limit this application. Other materials may also be used.
[0042] In some embodiments, such as Figure 2As shown, the cover 3 is a "U" shape, specifically a "U" shape made of metal, such as copper or stainless steel. Copper and stainless steel are just examples and are not intended to limit this application; other materials are also possible.
[0043] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the slot 1 and the cover 3 are fixed together by a snap-fit structure. Specifically, the slot 1 at the gap 4 has a stepped structure, and elastic snaps 31 are provided on both sides of the cover 3 inserted into the gap 4. The elastic snaps 31 extend outward at an angle opposite to the insertion direction and are used to snap onto the stepped structure to achieve fixation. Wherein, as Figure 2 As shown, two elastic buckles 31 are provided on each of the two sides of the cover 3, and the two elastic buckles 31 on one side correspond to two slots 1.
[0044] Among them, the slot 1 at the gap 4 includes a first slot section 13 and a second slot section 14. The inner diameter of the second slot section 14 is larger than the inner diameter of the first slot section 13 to form a stepped structure, and the first slot section 13 is close to the end 12 of the opening on the slot 1.
[0045] In some embodiments, the elastic buckle 31 has a normal state and a deformed state, wherein when the elastic buckle 31 is in the deformed state, it is subjected to an inward force, causing it to close inward.
[0046] like Figure 5 As shown, during the process of the cover 3 being inserted into the first slot section 13 from the opening end 12 of the slot 1, the elastic buckle 31 is squeezed by the first slot section 13, and the elastic buckle 31 switches from the normal state to the deformed state. Figure 6 and Figure 7 As shown, when the cover 3 is inserted into the second slot section 14, the elastic buckle 31 switches from the deformed state to the normal state and the elastic buckle 31 is engaged with the stepped structure.
[0047] In this embodiment, the protruding body 2 and the slot 1 are integrally formed, and the cover 3 is fixed by the cooperation of the elastic buckle 31 and the stepped structure, so that there is no hard and continuous interference between the protruding body 2 and the slot 1, which can effectively solve the problems of deformation and loosening after high temperature.
[0048] In some embodiments, such as Figure 2As shown, the cover 3 is provided with a receiving opening 32. When the elastic buckle 31 is deformed, it can be located in the receiving opening 32, so that the elastic buckle 31 is flush with its side, so that the cover 3 can slide in the first slot section 13, and when it reaches the second slot section 14, the elastic buckle 31 returns to the normal pop-out state, and the elastic buckle 31 is engaged with the stepped structure.
[0049] The cover 3 in this embodiment has a simple structure and is easy to manufacture. It can be mass-produced directly through conventional stamping production processes.
[0050] Some embodiments of this utility model also disclose a KEY position structure, including a protruding component of the KEY position structure described in any of the above embodiments and a groove (not shown) that mates with the cover 3, wherein the protruding component of the KEY position structure will not be described in detail here.
[0051] The positioning function can be achieved by the cooperation between the protruding body 2 and the groove, which can prevent the connector from becoming loose or misaligned during use and improve the reliability and stability of the connection.
[0052] like Figure 2 As shown, some embodiments of this utility model also disclose a connector, including the KEY bit structure protrusion component described in any of the above embodiments, wherein the KEY bit structure protrusion component will not be described in detail here.
[0053] In some embodiments, the connector is an RJ45 network interface, a D-Sub connector, a Molex power connector, etc. The RJ45 network interface, D-Sub connector and Molex power connector mentioned here are just examples and are not intended to limit this application. Other connectors are also possible.
[0054] In some embodiments, such as Figure 2 As shown, the connector also includes a housing 5, a raised body 2, and a slot 1, all of which are integrally molded plastic structures with the housing 5.
[0055] It is understood that the above embodiments only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this utility model, and can also make several modifications and improvements, all of which fall within the protection scope of this utility model.
