연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The invention claimed is: 1. An electrical connector comprising: an insulating housing; a contact held by the housing; and an operating member for operating the contact, wherein the housing includes an insertion recess into which a shaft-like terminal is inserted in a first direction, the contact includes a pair of elastic pieces facing each other, at least a part of the pair of elastic pieces is exposed to the insertion recess, each of the elastic pieces is in a cantilevered shape having a base end portion and a tip end portion, the pair of elastic pieces are inclined with respect to the first direction so that a distance between the tip end portions becomes narrower than a distance between the base end portions, the pair of elastic pieces respectively include clamp portions for clamping the terminal in predetermined clamping directions orthogonal to the first direction, the first direction is in a radial direction of the terminal, and the operating member includes a widening operating portion for widening a distance between the clamp portions of the pair of elastic pieces. 2. The electrical connector according to claim 1, wherein the operating member can shift toward the first direction and a second direction opposite to the first direction, the operating member shifts to a widening position according to shifting toward the second direction, and shifts to a widening released position according to shifting toward the first direction, and by the widening operating portion of the operating member that has shifted to the widening position, the distance between the pair of clamp portions is widened to a distance which enables the terminal to be inserted between the pair of clamp portions with no insertion force. 3. The electrical connector according to claim 2, wherein the operating member is held by the housing in a manner enabling the operating member to shift between the widening position and the widening released position. 4. The electrical connector according to claim 2, wherein the operating member includes a pair of pressurizing portions, and the pair of pressurizing portions pressurize the pair of elastic pieces, respectively so as to narrow a distance between the pair of clamp portions when the operating member is at the widening released position. 5. The electrical connector according to claim 4, wherein the operating member includes a pair of portions disposed on both sides across the pair of elastic pieces in the insertion recess, and the pair of pressurizing portions are provided on the pair of portions, respectively. 6. The electrical connector according to claim 5, wherein the operating member forms an open portion for opening a space between the pair of portions to the second direction. 7. The electrical connector according to claim 5, wherein the operating member includes an opening preventive portion that prevents the space between the pair of portions from opening to the second direction. 8. The electrical connector according to claim 2, wherein the insertion recess includes a guide groove for guiding the operating member to the widening position and the widening released position in the first and second directions. 9. The electrical connector according to claim 2, wherein the widening operating portion of the operating member includes a receiving portion for receiving the terminal at a position corresponding to the clamp portions when the operating member is at the widening position. 10. The electrical connector according to claim 2, further comprising: a holding mechanism for holding the operating member at the widening position. 11. The electrical connector according to claim 2, further comprising: a holding mechanism for holding the operating member at the widening released position. 12. The electrical connector according to claim 1, wherein the terminal includes a terminal of a fluorescent tube. 13. The electrical connector according to claim 12, wherein the fluorescent tube includes a cold cathode fluorescent tube, and the terminal includes an outer lead exposed from an end portion of the cold cathode fluorescent tube. 14. The electrical connector according to claim 13, wherein the fluorescent tube includes an external electrode fluorescent tube, and the terminal includes an electrode layer coated on a peripheral surface of an end portion of the external electrode fluorescent tube. 15. A liquid crystal display device comprising: a liquid crystal panel having a front face and a back face; a circuit board having a first surface facing the back face of the liquid crystal panel and a second surface opposite to the first surface; an electrical connector attached to the circuit board; a fluorescent tube for a backlight which is disposed between the back face of the liquid crystal panel and the first surface of the circuit board, and has a terminal on an end portion; and an inverter circuit which is disposed on the second surface of the circuit board and supplies electrical power to the fluorescent tube, wherein the electrical connector comprises: an insulating housing; a contact held by the housing; and an operating member for operating the contact, a longitudinal direction of the fluorescent tube is parallel to the back face of the liquid crystal panel, the housing includes an insertion recess into which a shaft-like terminal is inserted in a first direction, the contact includes a pair of elastic pieces facing each other, at least a part of each of the elastic pieces is exposed to the insertion recess, each of the elastic piece is in a cantilevered shape having a base end portion and a tip end portion, the pair of elastic pieces are inclined with respect to the first direction so that a distance between the tip end portions becomes narrower than a distance between the base end portions, the pair of elastic pieces include clamp portions for clamping the terminal in a predetermined clamping direction orthogonal to the first direction, respectively, the first direction is in a radial direction of the terminal, the operating member includes a widening operating portion for widening the distance between the clamp portions of the pair of elastic pieces, the clamp portions of the pair of elastic pieces of the contact of the electrical connector clamp the terminal of the end portion of the fluorescent tube between the back face of the liquid crystal panel and the first surface of the circuit board, the contact includes a lead connected to the inverter circuit, and the lead extends in the second surface of the circuit board.
