Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a bimetallic floating female end and a connector. Background Art

[0002] In practical applications, when the male and female ends of the connectors used in existing battery packs are plugged in, there are often cumulative errors in position due to the large area of ​​the PCB boards where the male and female ends are located, and when they are assembled with the corresponding PCBs, especially when multiple plug-in positions need to be arranged on the PCB, the position difference between the male and female ends is particularly prominent, often exceeding the correction amount of the conventional single metal female end, causing abnormal unilateral contact between the male and female ends, seriously affecting the conduction performance and causing abnormal temperature rise. At the same time, due to the unilateral plug-in, plugging and unplugging are often not smooth. Summary of the invention

[0003] In order to solve the problem in the prior art that the male end and the female end of the connector cannot be smoothly plugged in and out due to position deviation, the present invention provides the following technical solution.

[0004] A first aspect of the present invention provides a bimetallic floating female end, comprising: a floating body and a socket body made of metal material, wherein the floating body is suspended in the socket body;

[0005] The floating body includes a floating body, a side floating spring sheet, a side contact spring sheet and a male and female contact spring sheet. The floating body is a rectangular cavity structure formed by four side walls connected in sequence and having openings at the upper and lower ends. A pair of opposite side walls of the floating body are bent and extended toward the inside of the cavity at the upper openings respectively until they contact each other and then are bent in directions away from each other to form male and female contact spring sheets. Side floating spring sheets are respectively arranged on a pair of side walls of the floating body on which male and female contact spring sheets are formed. The side floating spring sheets extend from the bottom end to the outside of the cavity and then bend toward the direction of the cavity. Side contact spring sheets extending toward the outside of the cavity are respectively arranged on a pair of side walls of the floating body on which male and female contact spring sheets are not formed.

[0006] The socket body includes a socket body and a plurality of lower plate feet arranged at the lower end of the socket body. The socket body is a rectangular cavity structure that passes through the upper and lower parts and is surrounded by four side walls connected in sequence. A pair of opposite side walls are provided with side buckle holes, and the side buckle holes are adapted to the side contact spring sheets so that the floating body can be snapped into the socket body.

[0007] Furthermore, the side contact spring comprises an extension portion and a buckle portion, and the buckle portion is used for buckling with a corresponding side buckle hole on the socket body.

[0008] Furthermore, two parallel male and female contact spring sheets are arranged on each side wall provided with the male and female contact spring sheets.

[0009] Furthermore, two parallel side floating spring sheets are arranged on each side wall provided with the side floating spring sheets.

[0010] Furthermore, the number of the lower plate feet is 4, which are symmetrically located on two side walls of the socket body where no side buckle holes are provided.

[0011] Furthermore, the floating body is integrally stamped from a metal sheet.

[0012] Furthermore, the socket body is integrally stamped from a metal sheet.

[0013] Furthermore, a support portion is provided on the socket body. The support portion is provided at the bottom of the socket body and is formed by bending the bottoms of two opposite side walls of the socket body into the rectangular cavity of the socket body.

[0014] The second aspect of the present invention further provides a connector, comprising a male end and the bimetallic floating female end described in the first aspect.

[0015] Furthermore, the male end is a metal plate structure.

[0016] The bimetallic floating female terminal provided by the present invention has the following beneficial effects:

[0017] The bimetallic floating female end provided by the present invention includes a floating body and a socket body. The floating body is suspended and plugged into the socket body through the side floating springs and side contact springs arranged on its side walls. When there is a position deviation between the male end to be plugged in and the bimetallic floating female end, the floating body will move left and right in the socket body as the male end moves downward to compensate for the deviation, while also ensuring complete electrical connection between the floating body and the socket body and between the male and female contact springs and the male end, thereby achieving reliable plugging and unplugging between the male end and the bimetallic floating female end. In addition, the floating body and the socket body provided by the present invention are both stamped from metal plates. Given the good heat resistance of metal, they can provide a guarantee for reliable connection of the connector even in a high temperature environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Embodiment 1

[0028] like Figure 1-3 As shown, this embodiment provides a bimetallic floating female end, including: a floating body 1 and a socket body 2, wherein the floating body 1 is suspended and fixed in the socket body 2; the floating body 1 is integrally stamped by a metal sheet, including a floating body 101, a side floating spring 102, a side contact spring 103 and a male and female contact spring 104; the floating body 101 is a rectangular cavity structure surrounded by four side walls connected in sequence and having openings at the upper end and the lower end, and a pair of opposite side walls of the floating body 101 are bent and extended toward the inside of the cavity at the upper end opening until they are connected to each other. After the contact, they are bent in a direction away from each other to form male and female contact spring pieces 104. A pair of side walls of the floating body 101 formed with male and female contact spring pieces 104 are respectively provided with side floating spring pieces 102. The side floating spring pieces 102 extend from the bottom to the outside of the cavity and then bend in the direction of the cavity. A pair of side walls of the floating body 101 not formed with male and female contact spring pieces 104 are respectively provided with side contact spring pieces 103 extending to the outside of the cavity. The side contact spring pieces 103 include an extension part and a buckle part. The extension part is bent in a direction away from the cavity to form a buckle part. In this embodiment, two parallel male and female contact spring pieces 104 are provided on each side wall provided with male and female contact spring pieces 104, and two parallel side floating spring pieces 102 are provided on each side wall provided with side floating spring pieces 102.

[0029] The socket body 2 is integrally stamped and formed by metal sheets, and includes a socket body 201 and a plurality of lower plate feet 202 arranged at the lower end of the socket body 201. The socket body 201 includes four side walls, two adjacent side walls are vertically arranged, two opposite side walls are parallelly arranged, and the four side walls are sequentially connected to form a rectangular cavity that runs through from top to bottom, wherein a pair of opposite side walls are provided with side buckle holes 203, and the side buckle holes 203 are adapted to the buckle parts of the side contact springs 103, and are used for the floating buckle fixation of the floating body 1 and the socket body 2. In this embodiment, the number of the lower plate feet 202 is 4, and they are symmetrically located on the two side walls of the socket body 2 where the side buckle holes 203 are not provided.

[0030] It should be noted that when there is no position deviation between the bimetallic floating female end and the male end 3, as Figure 4 As shown, when the floating body 1 is plugged into the socket body 2, the buckle parts of the side contact springs 103 arranged on the two side walls of the floating body 1 are snapped into the corresponding side buckle holes 203 on the socket body 2, and at the same time, the side floating springs 102 arranged on the other two side walls of the floating body 1 are elastically contacted with the corresponding two side walls of the socket body 2. When the bimetallic floating female end is installed and used, the lower plate foot 202 is first installed in the mounting hole adapted by the PCB board 4, wherein the PCB board 4 is also provided with a plug-in hole penetrating the PCB board 4, and the plug-in hole is used to facilitate the male end 3 to be electrically plugged into the bimetallic floating female end from the front or back of the PCB board 4 according to actual conditions, and then the male end 3 is inserted between the male and female contact springs 104 arranged on the opposite two side walls, at which time the male end 3 is completely in contact with all the male and female contact springs 104 arranged on the two side walls, so as to realize the electrical connection between the male end 3 and the bimetallic floating female. When the position of the male end 3 deviates to the left relative to the position of the bimetallic floating female end, during the process of plugging the male end 3 with the bimetallic floating female end, as the male end 3 moves downward, the bimetallic floating female end slides to the left due to the leftward thrust of the male end 3, thereby achieving position compensation of the male end 3, and the male end 3 continues to move downward and is fully in contact with the male and female contact springs 104 set on both side walls. In the above process, due to the elastic setting of the side floating springs 102 and the male and female contact springs 104, the side floating springs 102 on the two side walls of the floating body 1 are always in elastic contact with the corresponding two side walls on the socket body 2, and the male and female contact springs 104 on each side wall are always in contact with the male end 3, thereby achieving a reliable electrical connection between the male end 3 and the bimetallic floating female end. Figure 5 When the position of the male terminal 3 deviates to the right relative to the position of the bimetallic floating female terminal, the bimetallic floating female terminal will slide to the right due to the rightward thrust of the male terminal 3, thus achieving position compensation of the male terminal 3. Based on the same principle, the male terminal 3 and the bimetallic floating female terminal can finally achieve reliable electrical connection, as shown in FIG. Figure 6 shown.

[0031] Embodiment 2

[0032] like Figure 7 As shown, this embodiment provides another bimetallic floating female end, which differs from the bimetallic floating female end provided in embodiment 1 in that a support portion 204 is further provided on the socket body 2 of the bimetallic floating female end provided in this embodiment, and the support portion is provided at the bottom of the rectangular cavity of the socket body 2, and is formed by bending the bottoms of two opposite side walls of the socket body 2 toward the rectangular cavity of the socket body 2, and is used to provide support force for the floating body 1 when the plugging and unplugging force test of the bimetallic floating female end and the male end 3 is performed, so as to facilitate the test; in addition, the setting of the support portion 204 can also avoid contact between the floating body 1 and the PCB board during the plugging process of the male end 3 with the bimetallic floating female end, thereby preventing the PCB board from being scratched.
