Connector and connecting method

1. A connector to be connected to a flexible conductor, the connector comprising:

a base member including two or more projections;

two or more contacts made of a conductive material and including projection accommodating portions of recess shape into which the two or more projections are separately inserted;

a housing holding the two or more contacts and arranged to face the base member; and

a cutting portion for cutting the flexible conductor between a pair of contacts among the two or more contacts to divide the flexible conductor into a pair of flexible conductor pieces, when a pair of projections corresponding to the pair of contacts among the two or more projections are separately inserted into the projection accommodating portions of the pair of contacts together with the flexible conductor, the flexible conductor being arranged between the base member and the housing and extending over the pair of contacts adjacent to each other,

wherein the pair of flexible conductor pieces divided by the cutting portion are sandwiched between lateral surfaces of the pair of projections and inner surfaces of the projection accommodating portions of the pair of contacts and come into contact with the inner surfaces of the projection accommodating portions of the pair of contacts, whereby the pair of contacts are electrically connected to the pair of flexible conductor pieces.

2. The connector according to claim 1 ,

wherein the cutting portion includes a cutting protrusion portion projecting on one of the base member and the housing and a cutting groove formed on the other of the base member and the housing and receiving the cutting protrusion portion when the pair of projections are inserted into the projection accommodating portions of the pair of contacts, and

wherein each of the cutting protrusion portion and the cutting groove has a width longer than a width of the flexible conductor in a second direction perpendicular to a first direction along a straight line connecting the pair of projections or a straight line connecting the pair of contacts.

3. The connector according to claim 2 ,

wherein the other of the base member and the housing on which the cutting groove is formed includes guide portions projecting on both sides of the cutting groove in the first direction, and

wherein the guide portion includes a recess arranged on the straight line connecting the pair of projections or the straight line connecting the pair of contacts and adapted to accommodate the flexible conductor.

4. The connector according to claim 3 , wherein the recess has a width shorter than the width of the flexible conductor in the second direction to temporarily hold the flexible conductor accommodated therein.

5. The connector according to claim 2 , wherein the cutting protrusion portion has a projecting height shorter than a projecting height of the pair of projections.

6. The connector according to claim 2 , wherein the cutting protrusion portion includes a cutting blade for cutting the flexible conductor.

7. The connector according to claim 1 ,

wherein each of the two or more contacts has a tubular portion and a contact-side flange formed at one end of the tubular portion,

wherein the housing includes two or more contact through-holes through which the tubular portions of the two or more contacts are passed and which are smaller than the contact-side flanges, and

wherein the tubular portions of the two or more contacts are passed through the two or more contact through-holes, and the housing is fixed to the base member with the contact-side flange being pushed toward the base member, whereby the two or more contacts are fixed to the base member.

8. The connector according to claim 7 ,

wherein the base member includes a housing fixing post projecting higher than the projection,

wherein the housing includes a post accommodating portion of recess shape, and

wherein the housing fixing post is accommodated in the post accommodating portion, whereby the housing is fixed to the base member.

9. The connector according to claim 1 , wherein the housing is made of an insulating material.

10. The connector according to claim 1 , wherein the housing includes a counter connector accommodating portion in which a part of a counter connector is to be accommodated.

11. The connector according to claim 1 , wherein the base member is made of an insulating material.

12. The connector according to claim 1 , wherein the flexible conductor is independently arranged between the base member and the housing.

13. The connector according to claim 1 ,

wherein the flexible conductor is arranged to be exposed on a surface of an insulating substrate main body, and

wherein the flexible conductor is arranged between the base member and the housing such that the flexible conductor faces the housing while a rear surface of the insulating substrate main body faces the base member.

14. The connector according to claim 1 , wherein the contact is a plug-type contact.

15. The connector according to claim 1 , wherein the contact is a receptacle-type contact.

16. A connecting method for connecting a pair of contacts held on a housing to a pair of flexible conductor pieces, the connecting method comprising:

arranging a pair of projections formed on a base member so as to face projection accommodating portions of recess shape of the pair of contacts;

arranging a flexible conductor between the housing and the base member so as to extend over the pair of contacts; and

pushing the housing and the base member to each other with the flexible conductor being sandwiched therebetween to insert the pair of projections into the projection accommodating portions of the pair of contacts together with the flexible conductor and to cut the flexible conductor between the pair of contacts with a cutting portion arranged on at least one of the housing and the base member so as to divide the flexible conductor into a pair of flexible conductor pieces, and sandwiching the pair of flexible conductor pieces between lateral surfaces of the pair of projections and inner surfaces of the projection accommodating portions of the pair of contacts to bring the pair of flexible conductor pieces into contact with the inner surfaces of the projection accommodating portions of the pair of contacts, whereby the pair of contacts are electrically connected to the pair of flexible conductor pieces.
