Description

Socket terminal

[ technical field ] A method for producing a semiconductor device

The present invention relates to a socket terminal, and more particularly to a socket terminal with a good contact effect.

[ background of the invention ]

A conventional socket connector installed in a housing of a fan generally includes an insulating housing and a socket terminal fixed to the insulating housing, wherein the socket terminal is used for inserting a plug terminal to form an electrical connection. In order to improve the problem that the socket terminal is in a vibration state for a long time due to the rotation of the fan, the problem of poor contact between the socket terminal and the plug terminal and the impedance is easily caused, in order to improve the problem, a plurality of contact parts are additionally arranged on two side walls of the socket terminal by technical personnel in the field, however, because the contact parts of the existing fan socket terminal are elastic sheets extending along the plugging direction, the length of the plugging part along the front-back direction is inevitably longer due to the increase of the number of the contact parts, when the socket terminal vibrates, the front part and the rear part of the plugging part are easily deviated along the left-right direction, the plug terminal is easily and strongly abutted against the elastic contact part at one side of the socket terminal and is not in contact with the elastic contact part at the other side of the socket terminal, the elastic contact part at one side strongly abutted against the plug terminal is easily deformed and failed, when the elastic contact part is deformed and failed, in the use process of the socket terminal, the socket terminal is in a vibration state for a long time, the relative position of the elastic contact part and the plug terminal is displaced, and the elastic contact parts on the two sides of the socket terminal are easy to be in poor contact with the plug terminal in the use process.

As shown in fig. 11, when the receptacle terminal 2 'is mounted to the terminal groove 11' of the insulative housing 1, the front and rear portions of the plugging portion 21 'are easily displaced due to a mounting error, causing the plugging chamber 215' to be displaced in the left-right direction and not to be well aligned with the insertion port 12', causing the first and second elastic contact portions 2132', 2142', 2133', 2143 'to be displaced in the left-right direction, and causing the plugging portion 21' to be displaced when the receptacle terminal 2 'vibrates, causing the first and second elastic contact portions 2132', 2142', 2133', 2143 'to be displaced in the left-right direction from the original mounting position of the receptacle terminal 2' when the front and rear portions of the plugging portion 21 'are displaced in the left-right direction due to the vibration caused by the fan, and at least a portion of the plug terminal 3' is located closer to one of the first and second side walls 213', 214' than to the other of the first and second side walls 213', 214', the plug terminal 3 'is easily in strong contact with the first elastic contact portions 2132', 2142 'and the second elastic contact portions 2133', 2143 'of the first sidewall 213' or the second sidewall 214', and the first elastic contact portions 2132', 2142 'and the second elastic contact portions 2133', 2143 'of the second sidewall 214' or the first sidewall 213 'are correspondingly in poor contact or not in contact, so that the first elastic contact portions 2132', 2142 'and the second elastic contact portions 2133', 2143 'that are in strong contact with the plug terminal 3' are further easily subjected to elastic fatigue failure due to a large force, and further the socket terminal 2 'and the plug terminal 3' are easily in poor contact. In fig. 11, the front of the socket part 21 'is deflected towards the first side wall 213' and the rear of the socket part 21 'is deflected towards the second side wall 214', and, at this time, when the plug terminal 3' is inserted into the plug cavity 215' from the insertion port 13', the plug terminal 3' strongly abuts against the first elastic contact portion 2142' of the second side wall 214' at the front portion of the plug portion 21', and the plug terminal 3 'is not in contact with the first elastic contact portion 2132' of the first side wall 213 'at the front of the mating part 21', the plug terminal 3 'is strongly in contact with the second elastic contact portion 2133' of the first side wall 213 'at the rear of the mating part 21', and the plug terminal 3 'is not in contact with the second elastic contact portion 2143' of the second sidewall 214 'at the rear of the plugging portion 21', causing poor contact between the receptacle terminal 2 'and the plug terminal 3' and increasing contact resistance, thereby making it difficult to achieve high-frequency signal transmission.

Therefore, there is a need for a new receptacle terminal to overcome the above problems.
