[0031] An embodiment of the present application provides a quick-lock electrical connector.
[0032] like Figures 1 to 3 As shown, a quick-lock electrical connector includes a plug 1 and a socket 2 that are plugged into each other, wherein the plug 1 includes a first shell and a pin located in the shell, and the socket 2 includes a second shell and a socket located in the shell.
[0033] The first shell includes a first mounting seat 11 and a first wrapping shell 12, the first wrapping shell 12 is located on the first end face of the first mounting seat 11, and the pin is located in the first wrapping shell 12, the second shell includes a second mounting seat 21 and a second wrapping shell 22, the second wrapping shell 22 is located on the second end face of the second mounting seat 21, and the jack is located in the second wrapping shell 22, and when the plug 1 and the socket 2 are plugged in, the first end face and the second end face are opposite and close to each other.
[0034] The first wrapping shell 12 is provided with matching holes 3 on the first end face on opposite sides, the first mounting seat 11 is provided with a slot 31 connected to the matching hole 3 on the side, a movable sheet 4 is provided in the slot 31, a locking hole 41 is provided on the movable sheet 4, an elastic sheet 5 is provided on the side wall of the first mounting seat 11, one end of the elastic sheet 5 is connected to the movable sheet 4, and the other end of the elastic sheet 5 is fixed to the first mounting seat 11 by a rivet 52. In a natural state, the elastic sheet 5 drives the movable sheet 4 to make the center of the locking hole 41 deviate from the center of the matching hole 3, so that a partial area of the locking hole 41 coincides with the matching hole 3.
[0035] Fixed guide pins 6 are provided on opposite sides of the second wrapping shell 22, one end of the fixed guide pin 6 is fixed on the second end face, and a conical fitting head 7 is provided on the end of the fixed guide pin 6 away from the second end face. The large diameter end of the conical fitting head 7 is connected to the fixed guide pin 6, and an annular groove 61 is provided on the outer periphery of the end of the fixed guide pin 6 close to the conical fitting head 7. The outer diameter of the fixed guide pin 6 at the annular groove 61 is smaller than the outer diameter of the large diameter end of the conical fitting head 7, and the locking hole 41 and the fitting hole 3 are provided for the conical fitting head 7 to pass through.
[0036] The conical mating head 7 is used to drive the movable piece 4 to move when the plug 1 and the socket 2 are plugged in. After the conical mating head 7 penetrates the mating hole 3, the tip of the conical mating head 7 enters the overlapping area of the locking hole 41 and the mating hole 3, so as to increase the overlapping area of the locking hole 41 and the mating hole 3 until the conical mating head 7 passes through the locking hole 41, and the annular groove 61 and the movable piece 4 are aligned. Under the elastic force of the elastic piece 5, the locking hole 41 is reset to make the movable piece 4 on one side of the locking hole 41 located in the annular groove 61, so that the socket 2 and the plug 1 form a stable connection.
[0037] When separation is required, an artificial external force is applied to the elastic sheet or the movable sheet 4 to increase the overlapping area of the locking hole 41 and the matching hole 3, so that the overlapping area of the locking hole 41 and the matching hole 3 can allow the conical matching head 7 to pass through, and then the plug 1 is pulled to separate the plug 1 and the socket 2.
[0038] Specifically, in one embodiment, the locking hole 41 is conical, and the elastic sheet 5 applies to the movable sheet 4 so that the small end of the conical locking hole 41 is aligned with the center of the matching hole 3, the large end of the conical locking hole 41 is for the conical matching head 7 to pass through, and the small end of the conical locking hole 41 is matched with the annular groove 61.
[0039] like Figure 3 As shown, in another embodiment, the locking hole 41 includes a first hole 42 and a second hole 43 that are interconnected, the inner diameter of the first hole 42 is smaller than the outer diameter of the large diameter end of the tapered mating head 7, the inner diameter of the first hole 42 matches the outer diameter of the fixed guide pin 6 at the position of the annular groove 61, and under the elastic force of the elastic sheet 5 in a natural state, the center of the first hole 42 is aligned with the center of the mating hole 3. When the plug 1 and the socket 2 are mated, after the tapered mating head 7 penetrates the first hole 42, the center of the second hole 43 of the movable sheet 4 is driven to approach the center of the mating hole 3 until the tapered mating head 7 passes through the second hole 43, the annular groove 61 and the movable sheet 4 are aligned, and under the elastic force of the elastic sheet 5, the center of the first hole 42 is close to the center of the mating hole 3, so that the side wall of the first hole 42 and the annular groove 61 are matched.
[0040] In a natural state, the elastic sheet 5 exerts a force on the movable sheet 4 away from the bottom of the slot 31, and a gap is provided between the end of the elastic sheet 5 close to the movable sheet 4 and the side wall of the first mounting seat 11; when the overlapping area of the locking hole 41 and the matching hole 3 is passed through by the conical matching head 7, there is a gap or mutual fit between the end of the elastic sheet 5 close to the movable sheet 4 and the side wall of the first mounting seat 11, and the gap between the elastic sheet 5 and the first mounting seat 11 provides space for pressing the elastic sheet 5. By manually pressing the elastic sheet 5 to expand the overlapping area of the locking hole 41 and the matching hole 3, that is, pinching the elastic sheets 5 on both sides of the plug 1 and pulling the socket 2, the plug 1 and the socket 2 can be separated, which is more convenient for personnel to quickly separate the plug 1 and the socket 2.
[0041] The elastic sheet 5 is provided with a bending structure 51 protruding toward the side wall away from the first mounting seat 11. The bending structure 51 is convenient for people to press, thereby improving the separation efficiency of the plug 1 and the socket 2.
[0042] The first wrapping shell 12 and the second wrapping shell 22 have a trapezoidal cross section perpendicular to the plugging direction of the socket 2 and the plug 1, so as to avoid plugging the plug 1 and the socket 2 in reverse and improve the efficiency of correctly docking the plug 1 and the socket 2.
[0043] One end of the pin is crimped to a wire or an FPC flexible board 8.
[0044] One end of the jack is crimped with a wire or an FPC flexible board 8

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
