Contact press-fitting apparatus
View Patent ↗It is an object of the present invention to provide a contact press-fitting apparatus which can perform the press-fitting of all of the contacts with high reliability, without leading to problems such as buckling of the contacts, even in cases where the array pitch of the contacts is uneven. The contact press-fitting apparatus comprises a supporting member which is inserted into the press-fitting head from a direction perpendicular to the press-fitting direction of the press-fitting head, and which supports the side surfaces of the contacts on the sides that the abutting part does not abut against.
1. A contact press-fitting apparatus comprising:
a board carrier which carries a board;
a connector carrier which carries a connector having substantially L-shaped legs;
a press-fitting head which respectively positions and press-fits numerous press-fitting parts disposed in the vicinity of the lower end of the substantially L-shaped legs of the connector in the board, the press-fitting head having an abutting part that abuts against shoulders disposed on the upper sides of the press-fitting parts; and
a supporting member which is inserted into the press-fitting head from a direction perpendicular to the press-fitting direction of the press-fitting head, and which supports side surfaces of the contacts on the sides that the abutting part does not abut against.
2. The contact press-fitting apparatus of claim 1 , wherein the board carrier is mounted on a base, the connector carrier is mounted on an upper base connected to the base and movable in a direction parallel to the board carrier, and the press-fitting head is pivotally mounted on the upper base.
3. The contact press-fitting apparatus of claim 2 , wherein the supporting member comprises a board slidingly disposed on the upper base, a link extending perpendicular to the press-fitting direction from the board away from the press fitting head in a press fitting position, and a plurality of supporting plates extending perpendicular to the press-fitting direction from the board towards the press fitting head in the press fitting position.
4. The contact press-fitting apparatus of claim 3 , wherein the support member slides between a supporting position, in which the supporting plates support the side surfaces of one or more of the contacts, and a retracted position, in which the supporting plates are remote from the contacts.
5. The contact press-fitting apparatus of claim 4 , wherein the link is operatively associated with an operating member, such that the link, the board, and supporting plates are moved in a direction perpendicular to the press-fitting direction by pivoting the operating member.
6. The contact press-fitting apparatus of claim 1 , further comprising a positioning plate which performs positioning of the legs when the respective contacts are press-fitted in the board PCB.
7. The contact press-fitting apparatus of claim 6 , wherein the positioning plate is disposed in the vicinity of the connector carrier.
8. The contact press-fitting apparatus of claim 7 , wherein the positioning plate is fastened at a tip end of a link, the link being supported by a pivoting shaft on a slide member that slides with respect to the base.
9. The contact press-fitting apparatus of claim 7 , wherein the link has a cam pin disposed thereon operatively associated with a cam groove formed in a member fastened to the base.
10. The contact press-fitting apparatus of claim 8 , wherein the link pivots between a position wherein the positioning plate aligns with the board and a position wherein the positioning plate is remote from the board.
11. The contact press-fitting apparatus of claim 1 , wherein the press-fitting head has a plurality of longitudinal grooves formed on an inside surface thereof at substantially the same pitch as the array pitch of the contacts.
