[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.
[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.
[0035] like Figure 1 — Figure 11 As shown, a snap structure that is easy to assemble and detach and resists high drops includes a first component 1 and a second component 2. The first component 1 is provided with a snap 11, and the second component 2 is provided with a locking recess 21 corresponding to and cooperating with the snap 11. The snap 11 has a middle through hole 111 or a middle recess, one end of which faces the locking recess 21, and the other end is connected to the first component 1; a protrusion 22 that cooperates with the middle through hole 111 or the middle recess of the snap 11 is provided in the upper and middle part of one long inner side wall of the locking recess 21, and two guide ribs 23 are provided at intervals on both sides of the corresponding protrusion 22 in the length direction of the other long inner side wall; a guide inclined surface for guiding the snap 11 is respectively provided on the opposite side of the protrusion 22 and the guide rib 23, and the shortest distance between the opposite sides of the protrusion 22 and the guide rib 23 is less than the thickness of the U-shaped snap 11; the snap 11 is made of elastic material. In actual use, the buckle 11 can be made of plastic material among elastic materials, and can also be made of elastic materials such as nylon PA66, PA12, etc.
[0036] like Figure 5 、 Figure 6 As shown, in this embodiment, the locking recess 21 of the second component 2 is rectangular. In actual use, the locking recess 21 can also adopt other shapes, such as a long arc structure.
[0037] like Figure 5 — Figure 7As shown, a protrusion 22 is provided in the upper middle portion of the long inner sidewall of the retaining recess 21, which engages with the central through-hole 111 or the central recess of the buckle 11. Two guide ribs 23 are provided along the length of the other long inner sidewall, spaced apart on either side of the protrusion 22. The overall length of the buckle 11 is slightly shorter than the length of the retaining recess 21; when the buckle 11 is inserted into the retaining recess 21, the two guide ribs 23 correspond to either side of the buckle 11.
[0038] like Figure 8 、 Figure 11 As shown, the shortest distance between the protrusion 22 and the guide rib 23 on opposite sides is less than the thickness of the U-shaped buckle 11. The guide rib 23 not only guides the buckle 11 during insertion, but also limits the lower end of the buckle 11 after insertion. Specifically, when the buckle 11 is inserted into the retaining recess 21, it cannot tilt away from the protrusion 22; to facilitate insertion and assembly, the buckle 11 must undergo an arch-bridge-like bending deformation. Under the action of the two guide ribs 23, both sides of the lower end of the buckle 11 deform toward the protrusion 22.
[0039] After the buckle 11 and the protrusion 22 are assembled in place, the bending deformation of the buckle 11 returns to a straight line. After the buckle 11 is assembled in place, the limiting effect of the guide rib 23 can prevent the buckle 11 from tilting and deforming toward the rib 23 as a whole, and it has the ability to resist high drops; using this technical measure, it has the advantage of not being disengaged when falling from a height. When disassembly is required, a round needle-shaped tool is required, and external force is used to cause the buckle 11 to deform into an arch bridge shape between the two guide ribs, so that the buckle 11 is disengaged, and it can be disassembled smoothly, thereby separating the first component 1 and the second component 2. Using this technical measure has the advantages of simple structure, easy installation, detachability, and the ability to not be disengaged when falling from a height.
[0040] like Figure 7 、 Figure 8 、 Figure 11 As shown, in actual use, the upper end of the guide rib 23 is flush with the upper end of the protrusion 22, and the lower end of the guide rib 23 is flush with the lower end of the locking recess 21. Because the protrusion 22 is located in the upper middle portion of one of the long inner side walls of the locking recess 21, when the buckle 11 is inserted into the locking recess 21 and the protrusion is inserted into the middle through hole 111 of the U-shaped buckle 11, the guide ribs 23 on both sides of its lower end retain the position.
[0041] like Figure 1 — Figure 4 、 Figure 11As shown, the buckle 11 can be a U-shaped buckle 11, with the U-shaped open end of the U-shaped buckle 11 connected to the first component 1 and the other end facing the locking recess 21. When the U-shaped open end of the U-shaped buckle 11 is connected to the first component 1, a central through hole 111 is formed to cooperate with the protrusion 22. In actual use, the buckle 11 can also have a square structure. The point where the buckle 11 and the protrusion 22 cooperate can be the central through hole 111 or a central recess that cooperates with the protrusion 22. For example, a square plate-shaped buckle 11 has a central recess on the side facing the protrusion 22 that cooperates with the protrusion 22. When the first component 1 and the second component 2 are engaged with each other, and when the U-shaped buckle 11 is inserted into the locking recess 21, the U-shaped buckle 11 is bent into an arch bridge shape at the protrusion 22. When the protrusion 22 is inserted into the middle through hole 111 of the U-shaped buckle 11, the lower end of the U-shaped buckle 11 is inserted between the protrusion 22 and the guide rib 23, and the U-shaped buckle 11 returns to a straight shape. The U-shaped buckle 11 has the advantages of simple structure and easy installation.
[0042] In actual use, the lower end of the U-shaped buckle 11 is provided with a third guide bevel 112 on the side facing the guide rib 23. A fourth guide bevel 113 is provided on the lower end of the U-shaped buckle 11 on the side facing the protrusion 22. The protrusion 22 and the guide rib 23 are each provided with a guide bevel on the opposite side of the buckle 11. The guide bevel on the side of the protrusion 22 is a first guide bevel 221, and the guide bevel on the side of the guide rib 23 is a second guide bevel 231. When the U-shaped buckle 11 is inserted, the third guide bevel 112 of the U-shaped buckle 11 mates with the second guide bevel 231, and the fourth guide bevel 113 mates with the first guide bevel 221. During actual use, disassembly is facilitated by the coordination of the third and fourth guide bevels 113 of the U-shaped buckle 11 with the third guide bevel 112. This technical measure facilitates insertion and disassembly.
[0043] In actual use, when the first component 1 is the housing, the second component 2 is the upper cover; when the first component 1 is the upper cover, the second component 2 is the housing. Specifically, the first component 1 is the housing, and the top of the side wall of the housing is provided with a plurality of snaps 11; the second component 2 is the upper cover, and the bottom of the side wall of the upper cover is provided with a plurality of said retaining recesses 21, and the snaps 11 correspond one-to-one with the retaining recesses 21. The first component 1 is the upper cover, and the bottom of the side wall of the upper cover is provided with a plurality of snaps 11; the second component 2 is the housing, and the top of the side wall of the housing is provided with a plurality of retaining recesses 21, and the snaps 11 correspond one-to-one with the retaining recesses 21.
[0044] The utility model provides a safety relay module, which comprises a PCBA board. A cavity for accommodating the PCBA board is formed between an upper cover and an outer shell, and the PCBA board is fixed on the upper cover or the outer shell.
[0045] The utility model provides a safety relay module, whose housing and upper cover can be repeatedly disassembled to meet the needs of repair, reduce the cost of product repair and realize the feasibility of later maintenance of the product; its buckle 11 can be firmly buckled together under the action of the protrusion 22 of the locking recess 21 and the guide rib 23, and has the function of not falling off from a height; the buckle 11, the protrusion 22 and the guide rib 23 respectively have guiding inclined surfaces, which are more convenient during installation and removal.
