Low insertion force connector
View Patent ↗The lever member includes a rotation fulcrum point portion which is attached to a rotation shaft of a terminal storage body to be rotatable, a lever operation portion which is a force point portion during a lever operation, a fitting operation point portion which performs a fitting operation while sliding a counterpart target guide portion to apply a force between the target guide portion and the fitting operation point portion along with a rotation operation about the rotation fulcrum point portion as a rotation center in response to the rotation operation of the lever operation portion, and a target fixation portion which is fastened to a target fixation portion of a terminal storage body and a counterpart fixation portion after the fitting is completed.
1. A low insertion force connector comprising:
a terminal storage body that includes a terminal storage portion storing a terminal corresponding to a fitting target with respect to a counterpart terminal of a counterpart connector of an electrical connection target, a connector fitting portion fitted to a counterpart fitting portion of the counterpart connector, and a target fixation portion fixed to a fixation portion of the electrical connection target or the counterpart connector after the fitting between the connector fitting portion and the counterpart fitting portion is completed; and
a lever member that includes a rotation fulcrum point portion attached to a rotation shaft of the terminal storage body to be rotatable, a lever operation portion serving as a force point portion during a lever operation, and an operation point portion fitting the terminal to the counterpart terminal while fitting the connector fitting portion to the counterpart fitting portion in a state where a target guide portion of the electrical connection target or the counterpart connector is slid to apply a force between the target guide portion and the operation point portion along with a rotation operation about the rotation fulcrum point portion as a rotation center in response to the rotation operation of the lever operation portion, wherein
the lever member includes a target fixation portion which is fastened to the target fixation portion of the terminal storage body and the fixation portion after the fitting is completed.
2. The low insertion force connector according to claim 1 , wherein
the lever member includes the operation point portion and includes a first guide portion guiding the target guide portion along with a rotation operation about the rotation fulcrum point portion as a rotation center, a second guide portion which communicates with the rotation fulcrum point portion and is able to guide the rotation shaft after the completion of the fitting, and a third guide portion which communicates with the first guide portion and is able to guide the target guide portion in the same direction as the rotation shaft after the completion of the fitting, and
the second guide portion and the third guide portion are formed so that the lever member moves relative to the terminal storage body to a fastening position of the target fixation portion of the lever member.
3. The low insertion force connector according to claim 2 , Wherein
the second guide portion and the third guide portion are formed to lock the rotation shaft and the target guide portion in a direction intersecting an axial direction of a fastening screw at the time of the fastening when the lever member moves relatively to the fastening position.
4. The low insertion force connector according to claim 1 , wherein
the terminal storage body includes a positioning portion on which the target fixation portion of the lever member is disposed at the time of the fastening.
5. The low insertion force connector according to claim 2 , wherein
the terminal storage body includes a positioning portion on which the target fixation portion of the lever member is disposed at the time of the fastening.
6. The low insertion force connector according to claim 3 , wherein
the terminal storage body includes a positioning portion on which the target fixation portion of the lever member is disposed at the time of the fastening.
