Description

Technical Field

[0001] The utility model relates to a connector, in particular to a floating plug-in connector. Background Art

[0002] The plug-in connector consists of a male connector and a female connector. When in use, the female connector is fixed and welded on the circuit board, and the male connector is arranged on the functional electronic component. When the male connector is inserted into the plug-in slot of the female connector, the male signal terminal on the male connector is in close contact with the female signal terminal of the female connector extending into the plug-in slot, thereby realizing circuit conduction and signal transmission.

[0003] The insulating body of the current female connector is an integrated structure. This structure ensures that after the female connector is welded on the circuit board, the position of the plug-in slot and the female signal terminal therein are fixed. When the male connector is inserted into the plug-in slot of the female connector, the position of the male connector and the electronic components thereon are fixed. At this time, if the gap between the side walls of other components on the circuit board and the outer side walls of the male connector and the electronic components thereon is too small due to processing or welding errors, interference will occur, resulting in the male connector being unable to be normally inserted into the plug-in slot of the female connector, or after insertion, it is impossible to ensure that the male signal terminal and the female signal terminal cannot stably transmit signals. In addition, the above-mentioned female connector structure also requires that the male connector must be plugged and unplugged in a straight line along the up and down direction when plugging and unplugging. If there is an angle between the push-pull force and the vertical direction during the plug-in and unplugging process, it will cause an angle between the plug-in slot connecting the male connector and the female end, which will damage the connector.

[0028] When in use, the welding foot of the female signal terminal 23 is welded on the circuit board. Since the female signal terminal fixed end retaining portion 231 of the female signal terminal 23 is fixed on the fixed insulating body terminal retaining portion 211 of the female fixed insulating body 21, the female fixed insulating body 21 of the female connector 22 maintains a fixed positioning state with the circuit board. Since a female signal terminal elastically deforms and floats 233 of a "J"-shaped bending structure is formed in the middle of the female signal terminal 23, the bending portion of the "J"-shaped bending structure is a rounded structure 2331 that can be elastically deformed, and the vertical section 233 extending up and down of the "J"-shaped bending structure 3 can swing left and right, the upper horizontal section 2334 and the lower horizontal section 2332 of the "J"-shaped bending structure can slide left and right and swing forward and backward, the elastic deformation floating part 233 of the female signal terminal can bend and deform in the up and down, left and right and front and back directions and produce a certain degree of twisting deformation, the female floating insulating body 22 can produce translation and tilt movement in a certain range of three-dimensional space on the female fixed insulating body 21, so that the plug-in slot 227 on the female floating insulating body 22 forms a floating structure, when the male connector 1 is inserted into the plug-in slot 227 of the female connector, the male signal terminal 12 and The female signal terminal 23 maintains a close contact state for conduction. Generally, a male signal terminal 12 accommodating groove is formed in the male connector 1. A male contact portion, a male holding portion and a male welding foot are formed on the male signal terminal 12. The male welding foot is used to be welded on the electronic component motherboard.

[0034] The fixed insulating body terminal retaining portion 211 is a plurality of retaining grooves extending up and down and arranged at intervals on the two opposite outer side walls of the female end fixed insulating body 21. The floating insulating body terminal retaining portion 221 is a retaining hole extending up and down and arranged on the bottom surface of the plug-in slot 227 of the female end floating insulating body 22. The female end signal terminal fixed end retaining portion 231 of the female end signal terminal and the female end signal terminal floating end retaining portion 232 of the female end signal terminal 23 are respectively provided with a fixed end retaining card point 2311 and a floating end retaining card point 2321 on the side walls.

The elastically deformable floating portion of the female signal terminal 23 is located in the gap between the female fixed insulating body 21 and the female floating insulating body 22, and the floating end retaining portion thereon extends into the retaining hole on the bottom surface of the plug-in slot 227 of the female floating insulating body 22, and is fixedly engaged with the side wall of the retaining hole through the floating end retaining card point 2321 thereon, and at the same time, the female signal terminal contact portion 235 of the female signal terminal 23 continues to extend upward into the plug-in slot 227, and the female signal terminal fixed end retaining portion 231 of the female signal terminal 23 extends to the outside of the female fixed insulating body 21 and extends downward toward the circuit board, and the female signal terminal fixed end retaining portion 231 is inserted into the retaining grooves on the two opposite side walls of the female fixed insulating body 21, and is fixedly engaged with the side wall of the retaining groove through the fixed end retaining card point 2311 thereon.
