Connector for receiving and electrically connecting with a cable
View Patent ↗A connector includes: a housing 3 accommodating at least one of a conductive contact 5 ; an insertion opening 4 to which a flat cable 2 can be inserted, the insertion opening 4 being provided in front part of the housing 3 and being defined by upper and lower walls 33 and 32 of the housing 3 at the top and bottom; and a lever 6 which is provided in the back part of the housing 3 and is turned to bring the contacts 5 into pressure contact with the flat cable 2 and establish electrical continuity therebetween. The contact 5 includes a first contact 5 A which is engaged with the housing 3 at such a position that press-fit forces produced in the direction orthogonal to the press-fit direction when the contact 5 A is press-fitted into the housing 3 are not in the same straight line.
1. A connector, comprising:
a housing accommodating a conductive contact;
an insertion opening to which a flat cable can be inserted, the insertion opening being provided in a front part of the housing and being defined by upper and lower walls of the housing at a top and bottom; and
a lever which is provided in a back part of the housing and is turned to bring the contact into pressure contact with the flat cable and establish electrical continuity therebetween, wherein,
the contact includes a first contact which is engaged with the housing at such a position that press-fit forces produced between a lower surface of the upper wall and an upper surface of the lower wall which define the insertion opening and produced in an orthogonal direction orthogonal to a press-fit direction in which the contact is inserted into the housing when the contact is press-fitted into the housing are not in a same straight line,
the first contact includes a terminal portion mounted on a circuit substrate located under the housing, a first protrusion protruding downward and producing a press-fit force downward when the first contact is press-fitted into the housing and a second protrusion protruding upward and producing a press-fit force upward when the first contact is press-fitted into the housing, and
the first protrusion is formed at a position shifted from the second protrusion in the press-fit direction, and
the second protrusion is located at a terminal portion side with respect to the first protrusion.
2. The connector according to claim 1 , wherein the orthogonal direction is a direction that the first contact comes into pressure contact with the flat cable.
3. The connector according to claim 2 , wherein
the orthogonal direction is a vertical direction,
the housing includes an engagement portion engaged with the protrusion, and
the first protrusion is engaged with the engagement portion at a position shifted in the press-fit direction from the center of an upper surface of the engagement portion in the press-fit direction.
4. A connector, comprising:
a housing accommodating a conductive contact;
an insertion opening to which a flat cable can be inserted, the insertion opening being provided in a front part of the housing and being defined by upper and lower walls of the housing at a top and bottom; and
a lever which is provided in a back part of the housing and is turned to bring the contacts into pressure contact with the flat cable and establish electrical continuity therebetween, wherein,
the contact includes a first contact provided with a contact-side engagement portion which is engaged with a housing-side engagement portion provided in the housing when the first contact is inserted into the housing, and
when the contact-side engagement portion is engaged with the housing-side engagement portion, movement of the first contact relative to the housing toward only a removal side of an insertion side and the removal side in an insertion/removal direction is limited by the engagement of the contact-side engagement portion with the housing-side engagement portion, wherein
movement of the first contact relative to the housing toward the removal side in the insertion/removal direction is limited by bringing a face of the contact-side engagement portion on the removal side in the insertion/removal direction into contact with a face of the housing-side engagement portion on the insertion side in the insertion/removal direction, and
the first contact is composed of a moving arm driven by a cam portion provided for the lever and a fixed arm fixed to the housing, the moving and fixed arms being joined with a joint spring portion to form a substantially H shape, and
the fixed arm is located below the moving arm while the contact-side engagement portion is provided in the fixed arm, and
the housing-side engagement portion is provided in the lower wall of the housing.
5. The connector according to claim 4 , wherein a step portion including the face of the housing-side engagement portion on the insertion side in the insertion/removal direction is formed at the lower wall of the housing.
6. The connector according to claim 4 , wherein the contact-side engagement portion is provided in a portion of the fixed arm on the insertion side in the insertion/removal direction with respect to the joint spring portion.
7. The connector according to claim 6 , wherein the housing includes an upper regulation portion which limits upward movement of the insertion side of the fixed arm in the insertion/removal direction.
8. The connector according to claim 4 , wherein
the contact-side engagement portion is provided in lower part of the fixed arm, and
the housing-side engagement portion is provided in upper part of the lower wall of the housing.
9. The connector according to claim 8 , wherein the housing-side engagement portion is provided on the insertion side in the insertion/removal direction with respect to a center in the insertion/removal direction, of the lower wall of the housing.
