Patent number: 9190770Abstract: After passing through respective contact insertion holes 3A to 3E of a guide connector 3 and penetrating the substrate 110, the contacts 120 are inserted into a female housing 10. After the electrical connection between the contacts 120 and female contacts 20 are respectively established, a slider 1 is pressed down, which causes pressing pins 4 and 5 to press a first movable body 50 and a second movable body 60. With this, a lower stage 50L of the first movable body 50 and a lower stage 60L of the second movable body 60 detach from restriction beams 84 and 85. This allows springs 141 and 142 to extend, to move the first movable body 50 and the second movable body 60 away from the contacts 120.Type: GrantFiled: April 10, 2014Date of Patent: November 17, 2015Assignee: J.S.T.

Patent number: 9172172Abstract: A guide connector includes a first movable body, a second movable body, a box-like body capable of accommodating the movable bodies, and a lid. The guide connector is positioned below a substrate. Contacts are inserted into a female connector after passing through contact insertion holes to of the guide connector and penetrating the substrate. After the electrical connection between the contacts and female contacts are respectively established, a slider is pressed down, which causes pressing pins and to press the first movable body and the second movable body. With this, a lower stage of the first movable body and a lower stage of the second movable body detach from restriction beams. This allows springs to extend, to move the first movable body and the second movable body away from the contacts.Type: GrantFiled: April 10, 2014Date of Patent: October 27, 2015Assignee: J.S.T. MFG. CO., LTD.Inventors: Satoru Shindo, Shinji Tasaka, Takamasa Yagi

Patent number: 9166333Abstract: It is an object of the present invention to prevent damages to a contact. A contact 130 having penetrated the substrate 110 is inserted into the female housing 30, and is electrically connected to a female contact 40. When the slider 1 is pressed down ward during this state, the first movable body 70 and the second movable body 80 are pressed down by the slider 1. This causes a lower stage 73 of the first movable body 70 and a lower stage 83 of the second movable body 80 to move below an upper wall 94 of the housing 90, and outer surfaces of the lower stages 73 and 83 no longer contact the upper wall 94. Then, expansion of a spring 120 moves the first movable body 70 and the second movable body 80 away from the contact 130.Type: GrantFiled: February 11, 2014Date of Patent: October 20, 2015Assignee: J.S.T.

Patent number: 8845349Abstract: A female contact 20 includes: a quadrangular tube 21; a curled portion 22 provided inside the quadrangular tube 21; and a curved portion 23, a projection 24 and a mounted portion 25 which are provided outside the quadrangular tube 21. The curved portion 23 is elastically displaced in a vertical direction. The quadrangular tube 21, the curved portion 23, and the mounted portion 25 are arranged so as to overlap one another when viewed from a direction orthogonal to a first wall 110 of the quadrangular tube 21. Further, the curved portion 23 and the mounted portion 25 are located within a width W of the first wall 110.Type: GrantFiled: October 2, 2012Date of Patent: September 30, 2014Assignee: J.S.T. Mfg.

Patent number: 7556516Abstract: A connector 8 includes a plug element 3, a short-circuiting element 4, and a latching element 50 to be latched at a first latching position and a second latching position. When the latching element 50 is at the second latching position, a short-circuiting piece 4m moves to a non-short-circuit position. The latching element 50 has latch portions 52 formed in a projecting manner, and the short-circuiting element 4 has latch receiving portions 41a. In a state where the plug element 3 is inserted into the socket element 2i, when the latching element 50 is at the second latching position, the latch portions 52 and the latch receiving portions 41a engage with each other to prevent separation between the socket element 2i and the plug element 3.Type: GrantFiled: May 7, 2008Date of Patent: July 7, 2009Assignee: J.S.T.
