[0008] The head of the socket terminal is formed with a mating protrusion extending away from the spring sheet, the side of the mating protrusion facing the plug interface forms a plug guiding inclined surface, and the side of the mating protrusion facing away from the plug interface forms a plug limiting inclined surface, and the plug guiding inclined surface and the plug limiting inclined surface gradually converge towards each other in a direction away from the spring sheet.
[0009] Furthermore, a stop platform is formed in the middle of the socket terminal, and the stop platform presses against the second limiting protrusion along the direction from the second end of the accommodating cavity toward the first end. The head of the socket terminal also forms a limit platform extending in the direction away from the mating protrusion, and the two ends of the spring sheet in the length direction respectively abut against the first limiting protrusion and the limit platform.
[0010] Furthermore, two first limiting protrusions spaced apart from each other along the width direction of the shell are provided on the wall of the accommodating cavity, and a notch is formed on each side of the second end of the elastic piece, and the two notches are respectively against each first limiting protrusion.
[0011] Furthermore, the first limiting protrusion is a semi-spherical protrusion.

[0032] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The present invention provides a socket structure of an electrical connector, which can be used in various vehicle-mounted electrical connectors, such as charging connectors, but is not limited to vehicle-mounted connectors. The socket structure of the electrical connector includes:
[0033] The housing 100 is made of an insulating material such as plastic. A housing 101 is formed in the housing 100 and extends through the housing along its length. A plug-in port 102 is formed at the first end of the housing 101, and a wire opening 103 is formed at the second end of the housing 101. A first limiting protrusion 104 and a second limiting protrusion 105 are provided on the wall of the housing 101. The first limiting protrusion 104 and the second limiting protrusion 105 are respectively formed on the wall surfaces facing each other of the cavity wall. The side wall surface at the port of the plug-in port 102 can be provided with a rounded corner 108 to facilitate smooth insertion and removal of the plug.
[0034] The socket terminal 200 can be made of any suitable conductive metal material. The socket terminal 200 is disposed in the accommodating cavity 101 , with the head of the socket terminal 200 being disposed adjacent to the plug port 102 .
[0035] The spring piece 300 is made of, for example, stainless steel. The spring piece 300 is arranged between the cavity wall and the socket terminal 200. The middle portion of the spring piece 300 in the longitudinal direction is pressed against the cavity wall of the accommodating cavity 101. The two ends of the spring piece 300 in the longitudinal direction are respectively pressed against the head and tail of the socket terminal 200. For example, the middle portion of the spring piece 300 in the longitudinal direction is elastically pressed against the cavity wall of the accommodating cavity 101 along a first direction, one end of the spring piece 300 in the longitudinal direction is elastically pressed against the head of the socket terminal 200 along a second direction, and the other end of the spring piece 300 in the longitudinal direction is elastically pressed against the tail of the socket terminal 200 along the second direction. The first direction is opposite to the second direction. The two ends of the spring piece 300 in the length direction also respectively abut against the first limiting protrusion 104 and the head of the socket terminal 200 to be limited between the first limiting protrusion 104 and the head of the socket terminal 200 along the length direction of the housing 100. The middle part of the socket terminal 200 also presses against the second limiting protrusion 105 along the second end of the accommodating cavity 101 toward the first end. The middle part of the spring piece 300 in the length direction can form a bent structure. The bent structure makes the two ends of the spring piece 300 in the length direction closer to the socket terminal 200, so that the two ends of the spring piece 300 in the length direction can better press against the head and tail of the socket terminal 200.
[0036] The head of the socket terminal 200 is formed with a mating protrusion 201 extending away from the spring piece 300. The side of the mating protrusion 201 facing the plug interface 102 forms a plug guiding slope 202, and the side of the mating protrusion 201 facing away from the plug interface 102 forms a plug limiting slope 203. The plug guiding slope 202 and the plug limiting slope 203 gradually converge towards each other in a direction away from the spring piece 300.
[0037] Since the socket structure of the electrical connector provided by the present invention has a mating protrusion 201 extending away from the spring 300 along the head of the socket terminal 200, the mating protrusion 201 is formed on the side facing the plug interface 102 to form a plug guiding inclined surface 202, and the mating protrusion 201 is formed on the side facing away from the plug interface 102 to form a plug limiting inclined surface 203, so when the socket structure of the electrical connector is plugged in or unplugged with the matching plug, whether the plug terminal 1 is inserted (the card head 11 of the plug terminal 1 can first enter the plug interface 102 and slide against the plug limiting inclined surface 203 toward the second end of the accommodating cavity 101 (see FIG. Figure 3 ), and finally the card position (plug in place, see Figure 4 ) on the plug limiting inclined surface 203) or pulled out (the clamping head 11 of the plug terminal 1 slides from the plug limiting inclined surface 203 toward the first end of the accommodating cavity 101 to the plug guiding inclined surface 202 and finally leaves the plug guiding inclined surface 202), in this process, the head of the socket terminal 200 will press the matching part of the spring piece 300 and the head, and the matching part of the spring piece 300 and the tail of the socket terminal 200 will elastically press the tail of the socket terminal 200, so that the plug terminal 1 and the socket terminal 200 form an elastic plug and pull, so that the plug terminal 1 and the socket terminal 200 The plugging and unplugging are more labor-saving and convenient. In addition, the spring piece 300 is limited between the first limiting protrusion 104 and the head of the socket terminal 200 along the length direction of the shell 100, and the middle part of the socket terminal 200 is pressed against the second limiting protrusion 105 along the second end of the accommodating cavity 101 toward the first end, so that the socket terminal 200 is also limited along the length direction of the shell 100, avoiding the problem of the socket terminal 200 easily moving along the plugging direction (the length direction of the shell 100) when the plug terminal 1 and the socket terminal 200 are plugged in and out, thereby improving the electrical connection stability of the plug and socket.
[0038] According to one embodiment of the present application, a stop platform 204 is formed in the middle of the socket terminal 200, and the stop platform 204 presses against the second limiting protrusion 105 along the direction from the second end of the accommodating cavity 101 toward the first end. The head of the socket terminal 200 also forms a limit platform 205 extending in a direction away from the mating protrusion 201, and the two ends of the spring piece 300 in the length direction respectively abut against the first limiting protrusion 104 and the limit platform 205.
[0039] See also Figure 6 and Figure 7 According to one embodiment of the present application, two first limiting protrusions 104 spaced apart from each other along the width direction of the shell 100 are provided on the wall of the accommodating cavity 101, and a notch 301 is formed on each side of the second end of the spring piece 300, and the two notches 301 correspond to each first limiting protrusion 104 one by one.
[0040] According to a specific embodiment of the present application, the first limiting protrusion 104 is a semi-spherical protrusion, and the second limiting protrusion 105 is a plate-shaped protrusion extending along the thickness direction of the housing 100 .
[0041] In addition, a protrusion 106 is formed on each side of the cavity wall of the accommodating cavity 101 along the width direction of the shell 100, and a limiting groove 107 is formed between each protrusion 106 and the cavity wall of the accommodating cavity 101. The two sides of the second end of the spring piece 300 are respectively limited in each limiting groove 107. A certain limitation prevents the spring piece 300 from being dislocated unnecessarily.
[0042] Furthermore, there are two accommodating cavities 101, with receptacle terminals 200 located in one of the two accommodating cavities 101 as a positive terminal and the other as a negative terminal. The mating plug also has two plug terminals 1. The electrical connector's receptacle structure also includes a wire retaining plug 3 secured to the wire opening 103. The wire retaining plug 3 has a wire retaining hole connecting the accommodating cavities 101 with the exterior of the housing 100.
[0043] See also Figure 8 According to another embodiment of the present application, the socket structure of the electrical connector further includes a flexible dust cover 400 (e.g., made of silicone or rubber) connected to the outside of the housing 100. The flexible dust cover 400 can cover the plug interface 102 and can be removed from the plug interface 102. Specifically, the flexible dust cover 400 includes a connecting ring 401, a connecting belt 402, and a cover body 403, which are connected in sequence. The connecting ring 401 is mounted on the housing 100, and the cover body 403 is used to cover the plug interface 102. The edge of the cover body 403 is also formed with a prying flange 404, which facilitates the cover body 403 to be opened with a finger after covering the plug interface 102.
[0044] It should be noted that the above embodiments merely represent preferred implementations of the present application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the present application. It should be noted that those skilled in the art may, without departing from the spirit of the present application, make various modifications and improvements, such as combining different features from the various embodiments, and all of these modifications and improvements should fall within the scope of protection of the present application.
