[0033] The following is for reference. Figures 1 to 4 The connection terminals of this application will be described in detail.

[0034] refer to Figure 1 According to an embodiment of the present invention, the connecting terminal includes a housing 100, an inner core 200, and a locking member 300. The housing 100 has an installation channel 110, and an insertion hole 111 is provided on the channel wall of the installation channel 110. An elastic part 120 is provided on the housing 100. The inner core 200 has a snap-fit ​​groove 210. The inner core 200 is detachably inserted into the installation channel 110, and the groove opening of the snap-fit ​​groove 210 is directly opposite the insertion hole 111. The locking member 300 is detachably installed on the housing 100. The locking member 300 can compress the elastic part 120 so that the elastic part 120 passes through the insertion hole 111 and is partially snapped into the snap-fit ​​groove 210.

[0035] Furthermore, during the assembly of the housing 100 and the inner core 200, the operator can insert the inner core 200 into the mounting channel 110, ensuring that the slot of the snap-fit ​​groove 210 on the inner core 200 is aligned with the through hole 111 on the channel wall of the mounting channel 110. At this time, the operator can install the locking member 300 onto the housing 100. During the installation of the locking member 300, the locking member 300 can compress the elastic part 120, causing the elastic part 120 to deform under the compression of the locking member 300, thereby allowing the elastic part 120 to pass through the through hole 111. The insertion hole 111 extends into the snap-fit ​​groove 210, thereby achieving a stable connection between the inner core 200 and the housing 100. When disassembling the housing 100 and the inner core 200, the operator can remove the locking member 300 from the housing 100. As the locking member 300 releases its pressure on the elastic part 120, the elastic part 120 can automatically disengage from the snap-fit ​​groove 210 under its own elastic force. At this time, the operator can smoothly pull the inner core 200 out of the installation channel 110 to achieve the disassembly between the inner core 200 and the housing 100.

[0036] It is understood that in the connection terminal of this application, through the cooperation of the locking member 300 and the elastic part 120, after the inner core 200 passes through the installation channel 110, the operator can make the elastic part 120 snap into or out of the snap groove 210 by installing or removing the locking member 300 on the housing 100, thereby facilitating the installation or removal between the inner core 200 and the housing 100; the disassembly and assembly between the inner core 200 and the housing 100 is more convenient.

[0037] In some embodiments of this utility model, the locking member 300 is provided with a sleeve hole 310, the wall of the sleeve hole 310 is provided with a first thread 330, and the circumferential surface of the housing 100 is provided with a second thread 140 adapted to the first thread 330.

[0038] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the mounting channel 110 on the housing 100 extends in the left and right direction, the locking member 300 is provided with a sleeve hole 310 extending in the left and right directions, the left end hole wall of the sleeve hole 310 is provided with a first thread 330, and the left end circumferential surface of the housing 100 is provided with a second thread 140 adapted to the first thread 330.

[0039] Furthermore, when connecting the locking member 300 and the housing 100, the operator can place the locking member 300 on the left end of the housing 100. By screwing the locking member 300 clockwise, the first thread 330 and the second thread 140 are fully engaged, thus installing the locking member 300 on the housing 100. During the clockwise screwing process, the locking member 300 can compress the elastic part 120, allowing the elastic part 120 to pass through the insertion hole 111 and insert into the snap-fit ​​groove 210, thereby achieving the connection between the housing 100 and the inner core 200. Next, when disassembling the locking member 300 and the housing 100, the operator can rotate the locking member 300 to the left to disengage the first thread 330 and the second thread 140, thereby disassembling the locking member 300 from the housing 100. During the process of rotating the locking member 300 to the left, the locking member 300 can avoid the elastic part 120, so that the elastic part 120 can disengage from the locking groove 210 under its own elastic force. At this time, the operator can smoothly pull the inner core 200 out of the housing 100 to separate the inner core 200 from the housing 100.

[0040] It is understandable that by providing a sleeve hole 310 on the locking member 300, a first thread 330 on the hole wall of the sleeve hole 310, and a second thread 140 adapted to the first thread 330 on the circumferential surface of the housing 100, the operator can quickly assemble and disassemble the locking member 300 and the housing 100 by rotating the locking member 300.

[0041] It is understandable that, due to the threaded connection between the locking element 300 and the housing 100, the connection of the locking element 300 to the housing 100 has good self-locking properties, thereby reducing the probability that the locking element 300 will automatically fall off the housing 100 under the influence of the external environment, so as to further improve the connection strength between the inner core 200 and the housing 100.

[0042] In a further embodiment of this utility model, reference is made to... Figure 3 A pressing portion 320 is formed on the wall of the sleeve hole 310. The pressing portion 320 can press the elastic portion 120 during the process of the locking member 300 being installed on the housing 100.

[0043] Furthermore, during the process of screwing the locking member 300 onto the housing 100, the pressing part 320 can push the elastic part 120 into the insertion hole 111, so that the elastic part 120 can deform towards the insertion hole 111, thereby allowing the elastic part 120 to pass through the insertion hole 111 and enter the snap-fit ​​groove 210.

[0044] It is understandable that by placing the extrusion part 320 inside the hole wall of the sleeve hole 310, the elastic part 120 can partially extend into the sleeve hole 310 before the extrusion part 320 extrudes the elastic part 120. Thus, under the limitation of the hole wall of the sleeve hole 310, when the extrusion part 320 extrudes the elastic part 120, the elastic part 120 can deform more smoothly toward the insertion hole 111, thereby reducing the probability that the elastic part 120 will deviate from the insertion hole 111 under the extrusion of the extrusion part 320.

[0045] In some other embodiments of this utility model, without considering the deformation direction of the elastic part 120, the extrusion part 320 can also be integrated on the edge of the sleeve hole 310.

[0046] In some embodiments of this utility model, the sleeve hole 310 includes a connecting section 311 and a clearance section 312 that are connected. The diameter of the clearance section 312 is larger than the diameter of the connecting section 311. A first thread 330 is provided on the connecting section 311. A pressing part 320 is formed on the edge of the hole of the connecting section 311 near the clearance section 312.

[0047] For example, such as Figure 3 As shown, the sleeve hole 310 includes a connecting section 311 and a clearance section 312 that are connected. The right end of the connecting section 311 is connected to the left end of the clearance section 312. A first thread 330 is provided on the left end hole wall of the connecting section 311. The hole diameter of the connecting section 311 is smaller than the hole diameter of the clearance section 312. A pressing part 320 is formed at the right end hole edge of the connecting section 311.

[0048] Understandably, since the aperture of the clearance section 312 is larger than that of the connecting section 311, the elastic part 120 can more easily enter the clearance section 312 during the process of the locking member 300 being screwed into the housing 100 to the right. When the locking member 300 continues to be screwed into the housing 100 to the right, the elastic part 120 can smoothly deform towards the insertion hole 111 under the pressure of the pressing part 320.

[0049] In order to facilitate the elastic part 120 to extend into the sleeve hole 310, in some embodiments of the present invention, the elastic part 120 is provided with a guide slope 121a, which is used to guide the elastic part 120 to extend into the sleeve hole 310.

[0050] For example, such as Figure 4 As shown, the elastic portion 120 extends in the left-right direction, and the left end of the elastic portion 120 is closer to the mounting channel 110 than the right end of the elastic portion 120, thereby forming a guide slope 121a on the elastic portion 120.

[0051] Understandably, the guide slope 121a allows the locking member 300 to be screwed into the housing 100 more smoothly, and the elastic part 120 to be more easily inserted into the sleeve hole 310 under the action of the guide slope 121a. Furthermore, during the pressing of the pressing part 320 against the guide slope 121a, the elastic part 120 can be more easily deformed towards the insertion hole 111 under the action of the guide slope 121a, so that the elastic part 120 can be more smoothly inserted into the insertion hole 111.

[0052] In a further embodiment of the present invention, the elastic part 120 includes an elastic segment 121 and a snap-fit ​​segment 122. One end of the elastic segment 121 is connected to the housing 100, and the other end of the elastic segment 121 is connected to the snap-fit ​​segment 122. A guide slope 121a is formed on the elastic segment 121. The elastic segment 121 can deform under the pressure of the locking member 300 so that the snap-fit ​​segment 122 is snapped into the snap-fit ​​groove 210 through the through hole 111.

[0053] For example, such as Figure 4 As shown, the elastic part 120 includes an elastic segment 121 and a snap-fit ​​segment 122. The elastic segment 121 extends in the left-right direction, and the left end of the elastic segment 121 is closer to the mounting channel 110 than the right end of the elastic segment 121. The upper end of the snap-fit ​​segment 122 is connected to the left end of the elastic segment 121, and the right end of the elastic segment 121 is connected to the housing 100. A guide slope 121a is formed at the end of the elastic segment 121 that is away from the mounting channel 110.

[0054] Understandably, during the process of the locking member 300 being screwed into the housing 100 to the right, the pressing part 320 can abut against the guide slope 121a on the elastic section 121 and press the elastic section 121 toward the installation channel 110, so that the elastic section 121 deforms toward the installation channel 110, thereby allowing the snap-fit ​​section 122 to pass through the insertion hole 111 and snap into the snap-fit ​​groove 210.

[0055] In order to improve the connection strength between the inner core 200 and the housing 100, in some embodiments of this utility model, multiple insertion holes 111 are provided at intervals along the circumference of the mounting channel 110, multiple elastic parts 120 are provided corresponding to the insertion holes 111, and the snap-fit ​​groove 210 is an annular groove.

[0056] For example, such as Figure 1 As shown, there are two insertion holes 111, which are distributed vertically. There are also two elastic parts 120, which are located on the upper and lower sides of the mounting channel 110 respectively. The snap-fit ​​groove 210 on the inner core 200 is an annular groove.

[0057] It is understandable that during the process of installing the locking member 300 on the housing 100, the locking member 300 can simultaneously press the two elastic parts 120 towards the installation channel 110, so that the two elastic parts 120 can deform simultaneously towards the installation channel 110, so that the two elastic parts 120 can respectively pass through the two insertion holes 111 and be simultaneously inserted into the snap-fit ​​groove 210, thereby realizing the connection between the inner core 200 and the housing 100.

[0058] It is understandable that the arrangement of multiple elastic parts 120 allows the inner core 200 to be simultaneously engaged in the snap-fit ​​groove 210 under the compression of the locking member 300 when it is connected to the housing 100, thereby increasing the connection strength between the inner core 200 and the housing 100.

[0059] It should be noted that the specific number of insertion holes 111 and elastic parts 120 can be set by the staff according to actual needs, and is not limited to two. There can also be three, four or even more insertion holes 111 and elastic parts 120.

[0060] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 The housing 100 is provided with a limiting protrusion 130, which is located on one side of the locking member 300 in its own installation direction. A fixing area 101 is formed between the limiting protrusion 130 and the locking member 300. The fixing area 101 is used to fix the housing 10 of the electrical equipment. An elastic part 120 is provided on the limiting protrusion 130.

[0061] It is understood that when using the connection terminal of this application, the operator can insert the housing 100 into the mounting hole of the outer casing 10 of the electrical equipment, and then insert the inner core 200 into the mounting channel 110 of the housing 100, and install the locking member 300 on the housing 100. During the installation of the locking member 300, the locking member 300 can squeeze the elastic part 120 so that the elastic part 120 extends into the snap-fit ​​groove 210 of the inner core 200 through the insertion hole 111. On the other hand, the locking member 300 can cooperate with the limiting protrusion 130 to clamp the edge of the mounting hole, thereby realizing the installation of the connection terminal of this application on the outer casing 10 of the electrical equipment.

[0062] The following is for reference. Figure 5 The electrical equipment of the second aspect of this application will be described in detail.

[0063] refer to Figure 5The electrical equipment provided according to the second aspect of the present invention includes the connection terminal provided in the first aspect of the present invention; the electrical equipment also includes a housing 10, on which a mounting hole is provided, the housing 100 is inserted into the mounting hole, and the edge of the mounting hole is engaged in the fixing area 101.

[0064] It is understood that when using the connection terminal of this application, the operator can insert the housing 100 into the mounting hole of the outer casing 10 of the electrical equipment, and then insert the inner core 200 into the mounting channel 110 of the housing 100, and install the locking member 300 on the housing 100. During the installation of the locking member 300, the locking member 300 can squeeze the elastic part 120 so that the elastic part 120 extends into the snap-fit ​​groove 210 of the inner core 200 through the insertion hole 111. On the other hand, the locking member 300 can cooperate with the limiting protrusion 130 to clamp the edge of the mounting hole, thereby realizing the installation of the connection terminal of this application on the outer casing 10 of the electrical equipment.

[0065] In a further embodiment of this utility model, reference is made to... Figure 5 The electrical equipment also includes a waterproof gasket 20, which is located within the fixing area 101 and between the housing 10 and the limiting protrusion 130.

[0066] It should be noted that the housing 100 is usually made of plastic, while the outer casing 10 of electrical equipment is usually made of metal. If the limiting protrusion 130 is in direct contact with the outer casing 10, it is easy to cause deformation and damage to the limiting protrusion 130. On the other hand, the connection between the limiting protrusion 130 and the outer casing 10 is not tight, resulting in poor sealing between the limiting protrusion 130 and the outer casing 10.

[0067] It is understandable that by providing a waterproof gasket 20 between the outer casing 10 and the limiting protrusion 130, on the one hand, the waterproof gasket 20 can separate the outer casing 10 and the limiting protrusion 130 to protect the limiting protrusion 130; on the other hand, the waterproof gasket 20 can improve the sealing between the outer casing 10 and the limiting protrusion 130, thereby improving the waterproof effect at the mounting hole on the outer casing 10.
