[0038] In order to make the purpose, technical scheme and advantage of the application more clear and obvious, the application is further described in detail below in combination with the drawings and examples.It should be understood that the specific examples described here are only used to explain the application and not to limit the application.

[0039] The electric connector is the core component of realizing electrical connection in electronic system, and through the insertion and separation of plug and socket, the closure or disconnection of circuit is completed, and it can realize signal transmission, power transmission or modular connection.

[0040] The male and female plug-in electric connector in prior art is usually to adopt metal contact point to establish stable electrical connection and maintain connection stability.But due to frequent plugging and unplugging, the metal contact point of male and female head will be worn, reducing the effective contact area, and then affecting the contact effectiveness.Meanwhile, the metal contact point is exposed to air and easy to oxidize to form oxide layer, increasing the contact resistance, leading to heating, signal transmission delay or even interruption, thereby affecting the connection stability.

[0041] In order to overcome the problem of contact failure of metal contact point in prior art, the utility model discloses a male and female plug-in electric connector, by setting multiple connection contact clamping ports, each connection contact clamping port is provided with a contact convex on the opposite connection clamping port side plate, to cooperate into a pair of plug-in multi-contact connection structure.Due to the multi-point contact provided by the electric connector of the application, not only the current passing capacity is improved, but also the effectiveness of connection is maintained through multiple groups of contacts, the connection stability is improved, and the connection performance of the electric connector is ensured.

[0042] The male and female plug-in electric connector disclosed in the embodiment will be further described below in combination with the drawings.

[0043] As shown in Figure 1 The male and female plug-in electric connector disclosed in the embodiment includes a male plug 10 and a female socket 20.The male plug 10 is provided with a socket matched with the female socket at one end, so that the male plug can be inserted into the female socket to cooperate into a male and female plug-in electric connector.The electric connector as a whole is in square structure.

[0044] Specifically, in combination with Figure 2 and Figure 3The diagram shows the structural schematics of a male plug and a female socket. The male plug includes multiple sets of male plug connection terminals 101. The female socket has multiple sets of blade terminals 201. All male plug connection terminals and the multiple sets of blade terminals are arranged in a parallel, equally spaced side-by-side layout. Figure 4 , Figure 5 and Figure 7 As shown, each male plug connection terminal 101 has a connection contact clip at one end. The blade ends of the multiple sets of blade terminals 201 of the female socket are inserted into the connection contact clips of the male plug connection terminals 101 to achieve the connection between the male plug and the female socket.

[0045] like Figure 6 The blade terminal disclosed in this embodiment is shown. It is an integral design, meaning that the blade and the terminal body are integrally formed, making it suitable for automated production. Specifically, the blade terminal body is flat, with one end being arc-shaped and the other end being blade-shaped.

[0046] Each set of male plug connection terminals includes at least two sets of connection contact clips, and each set of connection contact clips includes two connection clip side plates with the same structure and arranged opposite each other; the front end of each connection clip side plate is provided with a contact protrusion; the female socket includes multiple sets of blade terminals; each set of blade terminals is respectively connected to the connection contact clips of each set of male plug connection terminals, and fits against the contact protrusions provided on the connection contact clips to form a paired plug-in multi-contact connection structure.

[0047] like Figure 7 As shown, in one implementation, one end of the male plug connector has two sets of connection contact clips, namely a first connection contact clip 1015 and a second connection contact clip 1014. A bottom connecting plate 1012 is provided below the first connection contact clip 1015 and the second connection contact clip 1014. The first connection contact clip 1015 and the second connection contact clip 1014 are connected through the bottom connecting plate 1012. Furthermore, the first connection contact clip 1015, the second connection contact clip 1014, and the bottom connecting plate 1012 are integrated, arranged in a front-to-back configuration with the same orientation. In specific implementations, the number of connection contact clips can be multiple.

[0048] Furthermore, the connecting contact jaw includes a first connecting jaw side plate located on the left and right sides of the first connecting contact jaw, and a second connecting jaw side plate located on the left and right sides of the second connecting contact jaw, respectively. For example... Figure 7As shown, the first connecting contact jaw 1015 is provided with two first connecting jaw side plates 1018 symmetrically arranged. The second connecting contact jaw 1014 is also provided with two second connecting jaw side plates 1013 symmetrically arranged and of the same structure. The first connecting jaw side plate 1018 and the second connecting jaw side plate 1013 are designed in a long strip shape, and the front end inner side of the first connecting jaw side plate 1018 and the second connecting jaw side plate 1013 is provided with a contact bump. In this embodiment, the contact bump at the front end inner side of the first connecting jaw side plate 1018 is referred to as the first contact bump 1017, and the contact bump at the front end inner side of the second connecting jaw side plate 1013 is referred to as the second contact bump 1016. When the two groups of connecting contact jaws are matched with the blade terminals in the female socket to form an inclined plug and down pressure gusset type contact structure, the connecting jaw side plates of the two groups of connecting contact jaws are clamped on the blade terminals to form four-point contact.

[0049] In combination Figure 8 As shown, the four-point contact includes two contact points at the positions of the left and right contact bumps of the first connecting contact jaw and two contact points at the positions of the left and right contact bumps of the second connecting contact jaw. Among them, the position where the first connecting contact jaw is connected with the blade terminal can be regarded as a first connecting part 121, and the position where the second connecting contact jaw is connected with the blade terminal can be regarded as a second connecting part 122. Then, there is one contact point on the left and right sides of the first connecting part 121, and one contact point on the left and right sides of the second connecting part 122.

[0050] Since the electrical connector provided in this embodiment has two groups of contact points in front and back, which are independent contacts, when the contact points at one group of contact bumps fail, the contact points at the other group of contact bumps still maintain contact. The structure of the two groups of contact bumps ensures the effectiveness of the contact, and multiple groups of multi-point contact can improve the current passing capacity.

[0051] In addition, one or more contact bumps can also be arranged on the single-side connecting jaw side plate. For example Figure 9 As shown, two or more contact bumps are arranged on one connecting jaw side plate to increase the connection stability between the blade terminal and the connecting contact jaw. For example Figure 10 As shown, taking the first contact bump 1017 as an example, the shape of each contact bump in the transverse section is trapezoidal. For example Figure 11As shown, taking the first contact convex 1017 as an example, the shape of each contact convex in the horizontal direction section can be trapezoidal or circular arc. That is, in specific embodiments, the number of contact convexes arranged on the inner side of the front end of each side plate of the connecting clamp can be one or more, the shape of the contact convex in the transverse section is trapezoidal, and the shape of the contact convex in the horizontal direction section can be trapezoidal or circular arc. By arranging multiple contact convexes and trapezoidal or circular arc section shapes, the effective contact area between the male plug and the female socket is increased, thereby improving the stability of the electrical connector.

[0052] As shown in Figure 12 , the male plug further includes a male plug body 102, and the male plug connection terminals are fixed side by side on the male plug body 102. The male plug body is integrally formed as a whole or can be composed by upper and lower covers clamped together. The overall structure is a cuboid or a square, and a plurality of uniform spaces adapted to the shape of the male plug connection terminals are arranged inside the male plug body, so that the male plug connection terminals are fixed on the male plug body in a linear and side-by-side manner. The male plug body disclosed in the embodiment has high space utilization, can accommodate multiple male plug connection terminals side by side, and can be designed with a plastic double-layer shell, so it can adapt to a humid environment.

[0053] In order to further fix the male plug to the PCB board, as shown in Figure 2 , first fixing supports 103 are arranged on the left and right sides of the male plug body. One end of the first fixing support is fixed to the side wall of the male plug, and the other end is fixed to the PCB board, so as to fix the male plug to the PCB board.

[0054] As shown in Figure 13 and Figure 14 , the first fixing support 1031 includes a first fixing soldering leg 10313, a soldering leg connecting plate 10312, and a fixing plate 10311; the first fixing soldering leg 10313 and the fixing plate 10311 are respectively connected to the two sides of the soldering leg connecting plate 10312; the width d2 of the first fixing soldering leg 10313 is greater than the width d1 of the soldering leg connecting plate 10312, forming an ear shape. Thus, the area welded to the PCB board is increased.

[0055] In order to further increase the welding area of the first soldering leg when welded to the PCB board, and to enhance the bonding adhesion between the electrical connector and the PCB board, in specific implementation, the two sides of the first fixing soldering leg can be extended by a preset width, the left side can be extended by a preset width, or the right side can be extended by a preset width. As shown in Figure 13 , the part of the first fixing soldering leg whose width is wider than that of the connecting plate can be an extension of the area on both sides of the first fixing soldering leg. As shown in Figure 15 , it can also be an extension of the area on the left side of the first fixing soldering leg, or asFigure 16 As shown, the first fixed soldering feet can also be arranged in the extension of the area to the right of the first fixed soldering feet.

[0056] Further, in combination with Figure 3 , Figure 17 and Figure 18 , the female socket further comprises a female socket shell 202 and a second fixed support 203 arranged on the female socket shell, the second fixed support 203 comprising a support body 2034, second fixed soldering feet 2031 arranged at both ends of the support body 2034, and symmetrical fixed feet 2032 arranged on both sides of the support body.

[0057] Further, the second fixed support 203 further comprises a piercing fixed foot 2033 arranged in the middle of the support body 2034. The support body 2034, the second fixed soldering feet 2031, the piercing fixed foot 2033 and the symmetrical fixed feet 2032 are integrally formed. In an implementation, the second fixed support is an integrated fixed support, and the second fixed soldering feet contained in the second fixed support are used to fix the second fixed support with the female socket shell. The middle fixed foot in the middle is a piercing fixed foot, which is used to prevent the middle position of the second fixed support from being raised and possibly causing the second fixed support to fall off when the female socket is heated at high temperature.
