Cable connector
A cable connector includes an insulator, signal contacts supported in the insulator, wherein the signal contacts come in contact with the cable when the cable is inserted into the insulator, a pair of lock members which are rotatable between a locked position and an unlocked position, and springs supported on the insulator, wherein the springs retain the locked position and allow rotation of the lock members to the unlocked position by elastic deformation of the springs. Each spring includes a base-plate portion supported on the insulator, an elastically deformable portion extending from the base-plate portion, an end-extending portion extending from an end of the elastically deformable portion, and an engaging portion which engages with an associated lock member to integrate the spring with the associated the lock member.
1. A cable connector comprising:
an insulator, into which a thin cable is removably insertable to thereby define a insertion/removal direction, said cable including a pair of engaging portions on each side edge thereof with respect to a lateral direction of said cable;
a plurality of signal contacts which are supported in said insulator, which is connected to a circuit board, wherein said signal contacts come in contact with said cable when said cable is inserted into said insulator;
a pair of lock members which are independently rotatable, relative to said insulator, between a locked position and an unlocked position, wherein each of said lock members are engageable with an associated said engaging portion at said locked position and are not engageable with said associated said engaging portion at said unlocked position; and
a pair of springs which are supported on said insulator, wherein said springs retain said locked position of said lock members, respectively, and allow rotation of said lock members to said unlocked position by elastic deformation of said springs, respectively,
wherein each of said springs includes a base-plate portion which is supported on said insulator, an elastically deformable portion which extends from said base-plate portion in a direction parallel to said insertion/removal direction of said cable, an end-extending portion which extends from an end of said elastically deformable portion in a direction that is different to the extending direction of said elastically deformable portion, and an engaging portion which extends from an end of said end-extending portion in a direction toward said base-plate portion and parallel to said elastically deformable portion, wherein said engaging portion engages with an associated said lock member to integrate said spring with said associated said lock member.
2. The cable connector according to claim 1 , wherein a pair of rotational-shaft support recesses are formed on a surface of said insulator;
wherein said lock members are each provided with a rotational shaft which is rotatably fitted in a corresponding said rotational-shaft support recess, and
wherein said elastically deformable portions of said springs are provided on the opposite side of said insulator with respect to said lock members, respectively.
3. The cable connector according to claim 1 , wherein each of said lock members comprises a narrow-width portion, and a wide portion which is wider than said narrow-width portion in an arrangement direction of said lock members, and
wherein a cable insertion groove is formed in said insulator, said cable insertion groove being positioned in between a pair of said narrow-width portions when viewed in said insertion/removal direction.
4. The cable connector according to claim 1 , further comprising at least one ground contact, wherein said ground contact comes in contact with said cable when said cable is inserted into said insulator.
5. The cable connector according to claim 1 , further comprising a pair of indicator marks formed on said insulator, wherein, when viewed in said insertion/removal direction of said cable, said indicator marks are covered by said lock members when said lock members are positioned at said locked position, and said indicator marks are exposed by said lock members when said lock members are positioned at said unlocked position.
6. The cable connector according to claim 1 , further comprising a press-receiving portion formed on each of said pair of lock members, wherein said press-receiving portions can be pressed and operated by a pair of pressing portions formed on a single lock-release jig.
7. The cable connector according to claim 6 , wherein each of said press-receiving portions comprises a jig recess, wherein said pressing portions are engageable with said jig recesses, respectively.
