[0030] See also Figures 1 to 4 As shown, according to an embodiment of the present application, a terminal protection structure is provided. The terminal protection structure includes a main body 10 and a buckle assembly 20. The main body 10 includes a plurality of protective bodies, which are sequentially connected and enclosed along the same circumferential direction to form a cavity 101, and the cavity 101 is configured to accommodate the terminal body 30, and the buckle assembly 20 is used to connect at least two adjacent protective bodies.

[0031] When in use, the terminal body 30 is in the cavity 101. The protective body is arranged around the outer periphery of the terminal body 30 to protect the terminal body 30. Since the terminal protection structure in this embodiment is formed by a plurality of protective bodies, and two adjacent protective bodies are fixedly connected by the snap assembly 20, compared with the existing terminal protection structure, the terminal protection structure of the present application is simple in structure, and only the adjacent protective bodies need to be locked by the snap assembly 20, thereby locking the terminal body 30, which not only enhances the stability of the terminal body 30, but also can cover the button switch of the terminal body 30, so as to avoid the operator accidentally touching the button switch and causing personal safety hazards, thereby improving safety.

[0032] Specifically, the protective bodies in this embodiment can be set to two, three or more than three. Figures 1 to 32 shows the case where there are two protective bodies. Specifically, the two protective bodies in this embodiment include a first protective body 11 and a second protective body 12, and the buckle assembly 20 includes a clamping protrusion 21 and a clamping slot 22, wherein one of the clamping protrusion 21 and the clamping slot 22 is arranged on the first protective body 11, and the other of the two is arranged on the second protective body 12. That is to say, when the clamping protrusion 21 is arranged on the first protective body 11, the clamping slot 22 is arranged on the second protective body 12; when the clamping slot 22 is arranged on the first protective body 11, the clamping protrusion 21 is arranged on the second protective body 12. In this embodiment, by setting the protective bodies as the first protective body 11 and the second protective body 12, the structure is simple, and the two are locked by the clamping protrusion 21 and the clamping slot 22, which is convenient for assembly. In order to facilitate assembly, a guide inclined surface 211 is arranged on the clamping protrusion 21 in this embodiment, and the first protective body 11 and the second protective body 12 are convenient to be quickly assembled and connected together through the function of the guide inclined surface 211.

[0033] Furthermore, the first protective body 11 includes a first protective segment 111, a second protective segment 112 and a third protective segment 113, the second protective segment 112 and the third protective segment 113 are located on the same side of the first protective segment 111 and are respectively connected to the two ends of the first protective segment 111 to form a first groove 114 with the first protective segment 111; and the second protective body 12 includes a fourth protective segment 121, a fifth protective segment 122 and a sixth protective segment 123, the fifth protective segment 122 and the sixth protective segment 123 are located on the fourth protective segment 111. 21 and are respectively connected to the two ends of the fourth protection segment 121 to form a second groove 124 with the fourth protection segment 121; wherein the fifth protection segment 122 and the sixth protection segment 123 are both inserted into the first groove 114, the second protection segment 112 and the fifth protection segment 122 are arranged close to each other, the sixth protection segment 123 and the third protection segment 113 are arranged close to each other, and the second protection segment 112 and the fifth protection segment 122, as well as the sixth protection segment 123 and the third protection segment 113 are connected by the buckle assembly 20. During actual assembly, the fifth protection segment 122 and the sixth protection segment 123 are inserted into the first groove 114, at which time, the first groove 114 and the second groove 124 are buckled together to form a cavity 101 for accommodating the terminal body 30, which has a simple structure and is easy to process.

[0034] Optionally, the second protection segment 112 and the third protection segment 113 in this embodiment are both perpendicular to the first protection segment 111, and the fifth protection segment 122 and the sixth protection segment 123 are both perpendicular to the fourth protection segment 121. Transition arcs are provided between the second protection segment 112 and the third protection segment 113 and the first protection segment 111, and between the fifth protection segment 122 and the sixth protection segment 123 and the fourth protection segment 121, so as to avoid sharp corners in the terminal protection structure. In the present application, the protective body has multiple models, and a protrusion 104 is provided on one side of the protective body close to the cavity body 101, and the protrusion heights of the protrusion 104 on the protective bodies of different models are different. Since the protective body in this embodiment has multiple models, in actual use, the corresponding model of the protective body can be selected according to the external dimensions of the terminal body 30. In this embodiment, the protrusions 104 on the protection bodies of different types are different. By making the protrusion heights of the protrusions 104 different, cavities 101 of different sizes can be formed, thereby protecting terminal bodies 30 of different types.

[0035] That is to say, in order to form different types of protective bodies in this embodiment, it is only necessary to change the protrusion height of the protrusion 104. During the actual production and processing process, it is only necessary to change the process dimension of one part. The structure is simple and can improve the production and manufacturing efficiency of the terminal protection structure in this embodiment.

[0036] Furthermore, the protective body in this embodiment is provided with an avoidance groove 102, and the avoidance groove 102 is at least used to avoid structures such as the terminal head 31 on the terminal body 30. Of course, in other embodiments of the present application, the avoidance groove 102 can also be a structure such as an avoidance through hole, and as long as it is other deformation methods under the conception of the present application, it is within the protection scope of the present application. It can be understood that in the actual processing process, the avoidance groove 102 can be set or not set according to the specific structural form of the terminal body 30. The avoidance groove 102 can be a square groove, or a circular arc groove, etc., which is not specifically limited in this application.

[0037] Furthermore, a disassembly portion 103 is provided on the protective body in this embodiment, and the disassembly portion 103 is at least used to apply an external force to the protective body so as to remove the protective body from the terminal body 30. Optionally, the disassembly portion 103 in this embodiment includes a disassembly hole or a disassembly groove. When the protective body needs to be removed from the terminal body 30, it is only necessary to insert a screwdriver into the disassembly portion 103 and apply an external force to the protective body to remove the terminal protection structure from the terminal body 30. The structure is simple and easy to disassemble.

[0038] Furthermore, there is an overlapping portion between two adjacent protective bodies, that is, the overlapping portion of the second protective segment 112 and the fifth protective segment 122, and the overlapping portion of the sixth protective segment 123 and the third protective segment 113, and the disassembly portion 103 is arranged at the overlapping portion and passes through the overlapping portion. With such an arrangement, only one force is required to directly apply an external force to the two connected protective bodies, so that the two connected protective bodies can be removed simultaneously.

[0039] Optionally, the protective body in this embodiment is made of PBT (polybutylene terephthalate) plus GF (glass fiber), which improves the dimensional stability of the protective structure of the terminal body 30 under higher temperature conditions, and can be widely used in the field of electronic components. Applying it to the terminal body 30 can ensure high temperature resistance during operation, and the protective structure of the terminal body 30 has a certain strength and plasticity, which can ensure that it can normally lock the terminal body 30 and be removed from the terminal body 30, and has a long service life.

[0040] In combination with the above-mentioned embodiments, it can be known that after the first protective body 11 and the second protective body 12 in this embodiment are assembled together, a rectangular cavity 101 can be formed between the two. The shape of the rectangular cavity 101 allows the protective buckle to be applied to a variety of terminal bodies 30, and by opening an avoidance groove 102 on the protective structure of the terminal body 30, it can be adapted to various models of terminal bodies 30, which not only avoids interference between the protective structure of the terminal body 30 and the terminal body 30, but also improves the versatility of the protective buckle structure, and is widely used.

[0041] The protective buckle has a simple structure and consists of only two parts, a first protective body 11 and a second protective body 12. When in use, the terminal body 30 can be quickly clamped between the first protective body 11 and the second protective body 12 only through manual operation. The direction and position of locking the terminal body 30 can be determined according to the structure of the first protective body 11 and the second protective body 12, so that the locking work can be easily completed. In addition, the protective buckle is detachable and the first protective body 11 and the second protective body 12 can be removed from the terminal body 30 using a tool such as a flat-blade screwdriver to complete the installation and removal of the protective buckle, which is highly convenient.

[0042] That is to say, the present application can protect the push button switch of the terminal body 30 through the protective structure of the terminal body 30, so as to avoid harm to personnel due to improper operation and improve the safety of the terminal body 30. The protective structure of the terminal body 30 is cleverly designed and simple in structure. It is composed of only two parts, the first protective body 11 and the second protective body 12. It is very convenient to install. The terminal body 30 can be quickly locked between the first protective body 11 and the second protective body 12 only through manual operation. It is detachable, and the first protective body 11 and the second protective body 12 can be removed from the terminal body 30 with a flat-blade screwdriver, so as to realize the free installation and removal of the buckle and the terminal body 30, which is very convenient. In addition, the material of the protective structure of the terminal body 30 can make it have good high temperature resistance and extend its service life.
