Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a circular floating bimetallic female connector. Background Technology
[0002] In the prior art, the relay terminals on the automotive refrigeration control system have the following two problems in practical applications: (1) The PCB board area where the male and female terminals of this type of relay are located is large. When the male and female terminals are assembled with the corresponding PCB board, there is often an accumulated position error. Especially when there are multiple mating positions on the PCB board, the position error of the male and female terminals is particularly prominent, often exceeding the correction amount of the conventional single metal female terminal, resulting in a one-sided contact, which seriously affects the conduction performance of the relay. At the same time, due to the one-sided mating, it is often difficult to plug and unplug; (2) The operating environment temperature of the relay is high, sometimes as high as 150 degrees Celsius. The existing terminals have poor temperature resistance and cannot provide a guarantee for the reliable connection of the relay. Utility Model Content

[0023] Example 1
[0024] like Figure 1-3 As shown, this embodiment provides a circular floating bimetallic female end, including a metal female end shell and a metal floating interlocking spring 2. The female end shell is assembled from a female end upper cover 1, a female end body 3, and a female end lower cover 4. The female end body 3 is barrel-shaped, and the female end upper cover 1 and female end lower cover 4 are annular. The female end upper cover 1 and female end lower cover 4 are respectively disposed at the upper end and lower end of the female end body 3. The female end lower cover 4 is connected to the female end body 3 by a locking or welding method. Floating interlocking spring 2 The floating mating spring 2 is floatingly disposed within the outer shell of the female end and in contact with the inner wall of the female end body 3; the floating mating spring 2 includes a floating mating body 201 and multiple elastic contact pieces 202. The floating mating body 201 has a single-leaf hyperboloid structure and is hollowed out along the main axis. The multiple elastic contact pieces 202 are evenly spaced outward in the circumferential direction of the upper and lower end surfaces of the floating mating body 201, and the elastic contact pieces 202 are in contact with the inner wall of the female end body 3. Preferably, six elastic contact pieces 202 are provided in the circumferential direction of both the upper and lower end surfaces of the floating mating body 201; the lower end surface of the female end body 3 is provided with a lower plate foot 301, which is used to weld or lock the circular floating bimetallic female end onto the PCB board; the upper cover 1 and the lower cover 4 of the female end are made of stainless steel or copper, which can increase the mating force borne by the circular floating bimetallic female end.
[0025] It should be noted that, in this embodiment, the elastic contact piece 202 provided in the circumferential direction on the upper end surface of the floating mating body 201 extends toward the lower end surface of the floating mating body 201, and the elastic contact piece 202 provided in the circumferential direction on the lower end surface of the floating mating body 201 extends toward the upper end surface of the floating mating body 201. In other preferred embodiments, the elastic contact piece 202 disposed in the circumferential direction on the upper end face of the floating mating body 201 extends away from the lower end face of the floating mating body 201, and the elastic contact piece 202 disposed in the circumferential direction on the lower end face of the floating mating body 201 extends away from the upper end face of the floating mating body 201; or, the elastic contact piece 202 disposed in the circumferential direction on the upper end face of the floating mating body 201 extends towards the lower end face of the floating mating body 201, and the elastic contact piece 202 disposed in the circumferential direction on the lower end face of the floating mating body 201 extends away from the upper end face of the floating mating body 201; or, the elastic contact piece 202 disposed in the circumferential direction on the upper end face of the floating mating body 201 extends away from the lower end face of the floating mating body 201, and the elastic contact piece 202 disposed in the circumferential direction on the lower end face of the floating mating body 201 extends towards the upper end face of the floating mating body 201.
[0026] Example 2
[0027] This embodiment also provides a circular floating bimetallic female end. Unlike the first embodiment, the female end shell includes a female end upper cover 1, a female end body 3, and a female end lower cover 4. The female end upper cover 1 and the female end body 3 are integrally formed from metal material by stretching.
[0028] Example 3
[0029] This embodiment provides a connector, which includes a plurality of cylindrical male ends 6 and circular floating bimetallic female ends as described in Embodiment 1 or Embodiment 2, with the number of male ends 6 being adapted. Figure 3 As shown, in this embodiment, there are two circular floating bimetallic female terminals and two circular floating bimetallic female terminals 6. The two circular floating bimetallic female terminals are welded or locked to the front side of the PCB board 5 through the lower plate foot 301 to form an electrical connection with the PCB board 5. The two male terminals 6 located on the back side of the PCB board 5 are inserted into the circular floating bimetallic female terminals through the through holes in the PCB board 5 to form an electrical connection with the circular floating bimetallic female terminals. It should be noted that both the upper cover 1 and the lower cover 4 of the female terminal are annular. According to the installation requirements, the male terminal 6 can also be inserted into the circular floating bimetallic female terminal through the upper cover 1 of the female terminal. In this case, the male terminal 6 and the circular floating bimetallic female terminal are located on the same side of the PCB board.
[0030] like Figure 4As shown, when there is no positional offset between the male end 6 and the mating circular floating bimetallic female end, after the male end 6 is inserted into the circular floating bimetallic female end, the male end 6 contacts the inner wall of the floating mating body 201 to form an electrical connection. At this time, the axial direction of the male end 6 coincides with the main axis of the floating mating body 201.
[0031] like Figure 5 As shown, when the male end 6 is offset relative to the mating circular floating bimetallic female end, that is, the axial direction of the male end 6 does not coincide with the main axis of the floating mating body 201, during the process of inserting the male end 6 into the circular floating bimetallic female end, because the elastic contact piece 202 on the floating mating spring 2 is elastically set, the floating mating body 201 can be displaced in accordance with the mating force of the male end 6 it receives, so that the male end 6 and the inner wall of the floating mating body 201 come into contact to form an electrical connection.
[0032] The specific structures of the circular floating bimetallic female end provided in Embodiments 1 and 2 are described above and will not be repeated here.
