[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1The directions of “front, back, left, right, up, and down” are used as the basis.
[0020] See also Figures 1 to 5 The utility model discloses an electrical connection door shaft assembly, which is used in conjunction with a connecting terminal, and includes an outer shell 1. The left end of the outer shell 1 is provided with an open groove 2, and is plugged with an inner shell 3. The bottom of the inner shell 3 is provided with a hollow shaft 4, and the top of the outer shell 1 is provided with two mounting through holes 5; the insertion end of the inner shell 3 is slotted 6 and a first terminal shell 7 is plugged therein, the right end of the outer shell 1 is provided with an insertion groove 8, and a second terminal shell 9 is detachably plugged into the insertion groove 8, a sealing portion is provided between the second terminal shell 9 and the first terminal shell 7, and the sealing portion is used to seal the gap between the first terminal shell 7 and the second terminal shell 9; a locking portion is provided between the outer shell 1 and the inner shell 3.
[0021] The preferred technical solution in this embodiment is that the locking portion includes a limiting column 10 and an elastic pin 11, and the two ends of the limiting column 10 are respectively set as a step end 12 and a protruding end 13, and the width of the step end 12 is greater than the protruding end 13; the front and rear sides of the outer shell 1 are respectively provided with vertical limiting slots 14, and a limiting column 10 with the protruding end 13 outward is slidably arranged in the limiting slot 14 on each side, and a first plug hole is provided on the protruding end 13 of each limiting column 10, and an elastic pin 11 is inserted in each of the first plug holes, and the left end of the elastic pin 11 is bent upward and extended to a top higher than the top of the outer shell 1; the front and rear sides of the inner shell 3 are respectively provided with a slide groove 15 cooperating with the step end 12, and the left end of the slide groove 15 is provided with a card groove 16 extending downward and cooperating with the step end 12.
[0022] The preferred technical solution in this embodiment is as follows Figure 3 As shown in , the step end 12 of the limiting column 10 is a square column, which further restricts the movement of the limiting column 10 and prevents the limiting column 10 from rotating, which is not conducive to the insertion of the elastic needle 11.
[0023] The preferred technical solution in this embodiment is to ensure that the locking portion does not interfere with the plugging of the outer shell 1 and the inner shell 3, so that the outer shell 1 and the inner shell 3 can be plugged smoothly. Figures 1 to 3 As shown in the figure, the top of the limiting slot 14 is provided with a sub-slot 17 extending to the left, and the limiting column 10 is located in the sub-slot 17 when installed. After the outer shell 1 and the inner shell 3 are plugged and aligned, the step end 12 of the limiting column 10 slides in the slide groove 15, and then the limiting column 10 enters the limiting slot 14 through the left end of the slide groove 15 to avoid blocking caused by the step end 12 of the limiting column 10 during plugging.
[0024] The preferred technical solution in this embodiment is as follows Figure 1 and Figure 2As shown in the figure, the front and rear sides of the housing 1 are respectively provided with a protruding fixed end 18, and the fixed end 18 is provided with a second socket that cooperates with the elastic pin 11, and the right ends of the two elastic pins 11 are respectively inserted into the corresponding second sockets on this side; when the limit column 10 is in the auxiliary slot 17, its first socket is coaxial with the second socket to facilitate the installation of the elastic pin 11.
[0025] In the preferred technical solution of this embodiment, the elastic pin 11 is connected to the first socket in a sliding manner and connected to the second socket in a tight manner, so that the limiting column 10 can slide laterally on the elastic pin 11 without causing the elastic pin 11 to disengage from the second socket.
[0026] The preferred technical solution in this embodiment is as follows Figure 4 As shown in , the sealing portion is a rubber sealing ring 22, and the second terminal housing 9 is provided with an inner chamfer matched with the sealing ring 22. The inner chamfer is squeezed by the setting of the inner chamfer, thereby limiting the range of movement of the sealing ring 22.
[0027] The usage of the utility model: Figures 2 to 4 As shown in the figure, first, the connection terminal a20 and the connection terminal b21 are inserted into the first terminal shell 7 and the second terminal shell 9 respectively, wherein the connection terminal b21 can be plugged with the connection terminal a20; then, the wire of the connection terminal a20 is passed through the central axis at the bottom, and the first terminal shell 7 is plugged into the slot 6 of the inner shell 3; then, after the sealing ring 22 is put on the connection terminal a20, the inner shell 3 and the outer shell 1 are plugged and assembled, and the second terminal shell 9 plugged with the connection terminal b21 is inserted into the insertion slot 8 of the outer shell 1. During this period, the second terminal shell 9 can be freely plugged and unplugged in the insertion slot 8, and the electrical connection state of the connection terminal a20 and the connection terminal b21 is achieved by plugging and unplugging, that is, the connection after insertion is achieved. , disconnected after being pulled out; finally, when installing the electrically connected door shaft assembly, since the left end of the elastic pin 11 bends upward and extends to a top higher than the top of the outer shell 1, the top of the elastic pin 11 is deformed downward after being forced into contact with the installation door frame, so that the limiting column 10 connected to the elastic pin 11 also slides down in the limiting slot 14 synchronously, and the step end 12 is stuck in the slot 16 of the inner shell 3, thereby realizing the locking of the outer shell 1 and the inner shell 3; when the electrically connected door shaft assembly is disassembled, the top of the elastic pin 11 loses the support of the installation door frame and relies on its own elasticity to recover, and at the same time, the limiting column 10 on the elastic pin 11 also slides to the top of the limiting slot 14 synchronously, thereby releasing the locking state of the outer shell 1 and the inner shell 3.
