Description

本開示は、プローブピン、検査治具および検査ユニットに関する。 The present disclosure relates to probe pins, inspection jigs and inspection units.

カメラあるいは液晶パネル等の電子部品モジュールでは、一般に、その製造工程において、導通検査および動作特性検査等が行われる。これらの検査は、プローブピンを用いて、電子部品モジュールに設置されている本体基板に接続するための端子と、検査装置の端子とを接続することにより行われる。 In an electronic component module such as a camera or a liquid crystal panel, continuity inspection, operation characteristic inspection, and the like are generally performed in the manufacturing process. These inspections are performed by connecting the terminals for connecting to the main body board installed in the electronic component module and the terminals of the inspection device using probe pins.

このようなプローブピンとしては、特許文献１に記載されたものがある。このプローブピンは、電子部品の電極端子および被接続電子部品の電極端子に対してそれぞれ接触可能な一対のコンタクトと、一対のコンタクト間に介在して一対のコンタクトを接続する蛇行部とを備えている。 As such a probe pin, there is one described in Patent Document 1. This probe pin includes a pair of contacts that can contact the electrode terminals of the electronic component and the electrode terminals of the connected electronic component, respectively, and a meandering portion that connects the pair of contacts by interposing between the pair of contacts. There is.

特開２００２−１３４２０２号公報JP-A-2002-134202

前記プローブピンでは、蛇行部の伸縮方向に直行する幅方向の中心に一対のコンタクトをそれぞれ配置して、蛇行部を伸縮させた際に各コンタクトが幅方向に倒れないようにしている。このため、複数の前記プローブピンを幅方向に並べて配置すると、隣接する各コンタクトの配置間隔を狭くすることが難しくなり、例えば、狭ピッチ化された電子部品モジュールの一対の端子に対して、各コンタクトを同時に接触させた状態にすることができず、電子部品モジュールの狭ピッチ化に対応することができない場合がある。 In the probe pin, a pair of contacts are arranged at the center in the width direction perpendicular to the expansion / contraction direction of the meandering portion so that the contacts do not fall in the width direction when the meandering portion is expanded / contracted. For this reason, when a plurality of the probe pins are arranged side by side in the width direction, it becomes difficult to narrow the arrangement interval of the adjacent contacts. For example, for a pair of terminals of the narrow pitched electronic component module, each of the probe pins is arranged. It may not be possible to bring the contacts into contact with each other at the same time, and it may not be possible to cope with the narrowing of the pitch of the electronic component module.

本開示は、接触対象物の狭ピッチ化に対応可能なプローブピン、このプローブピンを備えた検査治具、および、この検査治具を備えた検査ユニットを提供することを目的とする。 It is an object of the present disclosure to provide a probe pin capable of narrowing the pitch of a contact object, an inspection jig provided with the probe pin, and an inspection unit provided with the inspection jig.

Therefore, when an external force in the X1 direction is applied, the second contact portion 41 contacts the surface of the terminal 60 and is on the other side (that is, the second direction) in the second direction Y with respect to the side surface 401 of the second contact portion 40. In Y, the second contact portion 40 moves from the side surface 401 in the second direction Y to the side opposite to the side where the elastic portion 20 is arranged). For example, even if a film is formed on the surface of the terminal 60, the film can be removed by the wiping operation of the second contact portion 41, so that the influence of the film formation on the contact reliability and the like can be reduced.

また、図４に、Ｘ１方向の外力に加えて、第１接触部３０の第１接点部３２１、３３１に対して、ソケット１００の内部に向かうＸ２方向の外力を加えた場合の弾性部２０の状態を示す。この場合においても、弾性部２０は、隣接する弾性片２１、２２が接触することなく弾性変形し、第２接点部４１によって、Ｘ１方向の外力のみが加えられた場合と同様のワイピング動作が行われる。第１接点部３２１、３３１は、Ｘ２方向の外力によって、ソケット１００の内部に向かって第１方向Ｘに沿って移動する。 Further, in FIG. 4, in addition to the external force in the X1 direction, the elastic portion 20 of the elastic portion 20 when an external force in the X2 direction toward the inside of the socket 100 is applied to the first contact portions 321 and 331 of the first contact portion 30. Indicates the state. Even in this case, the elastic portion 20 is elastically deformed without contacting the adjacent elastic pieces 21 and 22, and the wiping operation similar to the case where only the external force in the X1 direction is applied by the second contact portion 41 is performed. Will be. The first contact portions 321 and 331 move along the first direction X toward the inside of the socket 100 by an external force in the X2 direction.
