Electrical connector with a separate releasing operation portion attached to the lock arm main body

1. An electrical connector, comprising:

a contact;

a housing retaining the contact; and

a plurality of lock arms configured to catch a mating connector, each of the lock arms having an arm main body and an attachment portion each having a vertical and a horizontal wall integrally formed with the housing and a releasing operation portion, the releasing operation portion has a plurality of recesses for receiving the horizontal walls of the attachment portions, formed separately from the housing and attached to the arm main body.

2. The electrical connector of claim 1 , wherein the releasing operation portion is configured to be pushed to deflect the arm main body and release the mating connector from each of the lock arms.

3. The electrical connector of claim 1 , wherein at least two of the arm main bodies adjacent to each other are joined by the releasing operation portion.

4. The electrical connector of claim 3 , wherein each recess receives the attachment portion of one of the arm main bodies.

5. The electrical connector of claim 4 , wherein the releasing operation portion has an engagement portion configured to restrict disengagement of the attachment portion from the recess.

6. The electrical connector of claim 5 , wherein each recess of the releasing operation portion receives the attachment portion in a first direction perpendicular to a second direction in which the arm main bodies are adjacent to each other.

7. The electrical connector of claim 1 , wherein the housing is integrally formed with a contact accommodating portion receiving the contact and a mechanism accommodating portion.

8. The electrical connector of claim 7 , wherein the mechanism accommodating portion receives an electric wire connection mechanism connecting an electric wire to the contact.

9. The electrical connector of claim 8 , wherein the arm main body is supported on the contact accommodating portion in front of the mechanism accommodating portion.

10. The electrical connector of claim 9 , wherein the mechanism accommodating portion has an opening disposed between a rear end portion of the arm main body and the electric wire connection mechanism.

11. The electrical connector of claim 10 , wherein the housing has a protection wall disposed in a vicinity of each of the lock arms.

12. The electrical connector of claim 11 , wherein the protection wall is formed integrally with the arm main body in a single piece.
