[0040] The technical solutions of the present application are described in detail below with reference to the accompanying drawings.

[0041] Embodiment 1

[0042] As Figure 1As shown, a side buckle high-voltage connector includes a male end 2 and a female end 1 connected to each other. The male end 2 includes a male end plastic protective sleeve, and the female end includes a female end plastic inner core (not shown in the figure, inside the female end plastic protective sleeve) and a female end plastic protective sleeve 11 sleeved outside the female end plastic inner core. Terminals (not shown in the figure, the terminals are conventional structures in the industry) are arranged inside the male end plastic protective sleeve and inside the female end plastic inner core for connection.

[0043] Buckle grooves are separately formed at both end faces of the female end plastic protective sleeve 11, and buckles 131 protruding outward are arranged at the corresponding positions of the female end plastic inner core. By buckling the buckles 131 into the buckle grooves, the female end plastic inner core and the female end plastic protective sleeve 11 are assembled.

[0044] As shown in Figure 2 , Figure 3 At least one side wall of the female end plastic protective sleeve 11 is provided with a lock assembly 12 for preventing the female end plastic protective sleeve 11 from falling off the male end plastic protective sleeve. Figure 4 As shown in

[0045] The free end of the lock assembly 12 is provided with a convexity 123 protruding outward for locking. In order to facilitate the insertion of the lock assembly 12 into the female end plastic protective sleeve 11, the corner edge 124 of the convexity 123 is arranged in a circular arc shape.

[0046] The outer side of the female end plastic protective sleeve 11 is provided with a side spring arm 112 gradually inclined to the outside. The middle part of the side spring arm 112 is provided with a spring arm limiting beam 113. When the female end plastic protective sleeve 11 is inserted into the male end plastic protective sleeve, the side spring arm 112 is stressed and easily inclined downward. When the side spring arm 112 contacts the lock assembly 12, the upward reaction force of the lock assembly 12 can prevent the side spring arm 112 from moving downward excessively, thereby ensuring the tightness of the connection between the two, and preventing the female end plastic protective sleeve 11 from being easily loosened from the male end plastic protective sleeve.

[0047] Figure 5The diagram shows the pre-installed structure of the locking assembly 12 and the female end plastic protective sleeve 11. The locking assembly 12 fixed side arm 121 is inserted along the limiting track 111 inside the female end plastic protective sleeve. When the locking assembly protrusion 123 cooperates with the spring arm limiting beam 113 of the side spring arm of the female end plastic protective sleeve, the pre-installed state is achieved.

[0048] Figure 6 This is a schematic diagram showing the assembly of the locking assembly 12 and the female plastic protective sleeve 11. When the female end 1 and male end 2 are inserted, the locking assembly 12 is pushed to the locked position. At this point, the protrusion 123 of the locking assembly 12 has already passed the spring arm limiting beam 113 of the female plastic side spring arm 112. During the locking process, the locking assembly 12 advances along the limiting track 111. The side spring arm 112 is pressed down and then bounces back by the male plastic sleeve, producing a clear feedback sound. After the locking assembly 12 is in place, it restricts the downward pressure of the side spring arm 112, ensuring the mating effect.

[0049] Example 2

[0050] like Figure 7 As shown, a side-clamp high-voltage connector includes: a male terminal 2 and a female terminal 3 that are mutually mated and connected. The male terminal 2 includes a male terminal plastic protective sleeve, and the female terminal includes a female terminal plastic inner core (not shown in the figure, inside the female terminal plastic protective sleeve) and a female terminal plastic protective sleeve 31 sleeved on the outside of the female terminal plastic inner core. Terminals for connection (not shown in the figure, the terminals are of conventional industry structure) are respectively provided inside the male terminal plastic protective sleeve and inside the female terminal plastic inner core.

[0051] The two end faces of the female end plastic protective sleeve 31 are provided with snap grooves, and the corresponding part of the female end plastic inner core is provided with outwardly protruding snap 331. By snapping the snap 331 into the snap groove, the female end plastic inner core and the female end plastic protective sleeve 31 are assembled.

[0052] like Figure 8 , Figure 9 As shown, a locking assembly 32 for preventing the female end plastic protective sleeve from falling off from the male end plastic protective sleeve is provided on at least one side wall of the female end plastic protective sleeve 31. Figure 10 As shown, the locking assembly 32 in Embodiment 2 has a three-layer structure, consisting of a bottom locking spring arm 322, a middle fixed side arm 321, and an upper pressing block 324. One end of the locking spring arm 322 is fixed to one end of the fixed side arm 321, and the other end of the locking spring arm 322 is suspended and gradually tilted upward. The locking spring arm 322 has a certain elasticity, and when the locking spring arm 322 is pressed downward, it will generate a certain upward reaction force.

[0053] The free end of the locking buckle elastic arm 322 is provided with a locking convex 323 protruding outward, and the corner of the convex 323 is provided with a circular arc shape to facilitate the insertion of the female plastic protective sleeve 31 into the locking buckle assembly 32.

[0054] The outer side of the female plastic protective sleeve is provided with a baffle 314 which can be clamped into the gap between the fixed edge arm 321 and the pressing block 324 of the locking buckle assembly 32.

[0055] The outer side of the female plastic protective sleeve 32 is provided with a side elastic arm 312 which is gradually inclined outward, and the middle part of the side elastic arm 312 is provided with an elastic arm limiting beam 313. When the female plastic protective sleeve 31 is inserted into the male plastic protective sleeve, the side elastic arm 312 is stressed and easily inclined downward, and when it contacts the locking buckle assembly 32, the side elastic arm 312 cannot move downward excessively due to the upward reaction force of the locking buckle assembly 32, thereby ensuring the tight connection between the two and preventing the female plastic protective sleeve 31 from being easily detached from the male plastic protective sleeve.

[0056] As shown in the drawings, Figure 11 When the locking buckle assembly 32 is inserted along the limiting track 311 in the female plastic protective sleeve, and the convex 323 of the locking buckle assembly cooperates with the elastic arm limiting beam 313 of the side elastic arm of the female plastic protective sleeve, the preloading state is achieved.

[0057] As shown in the drawings, Figure 12 When the female end 3 and the male end 2 are inserted, the locking buckle assembly 32 is pushed to the locked position, and the convex 323 of the locking buckle assembly 32 has jumped over the elastic arm limiting beam 313 of the side elastic arm 312 of the female plastic protective sleeve. During the process of pushing the locking buckle assembly 32 to the locked position, the locking buckle assembly 32 advances along the limiting track 311, and finally the baffle is clamped between the fixed edge arm 321 and the pressing block 324. In this embodiment, the user can press the pressing block with his fingers, and because the surface area of the pressing block is large, a better finger pressing contact area is obtained.

[0058] In addition, the outer side wall of the male plastic protective sleeve is clamped with a soldering sheet for soldering and fixing with an external PCB.

[0059] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
