Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-row connector in which contacts are provided in a plurality of rows inside a housing.

[Conventional technology]

Conventionally, as a connector, there is a cable connector as shown in FIG.

The cable connector has a conductive contact 3, such as a socket contact, connected to one end of the cable 1, and a housing 5 made of an electrically insulating material incorporating the contact 3. There is.

The contact 3 is a socket portion 7 into which a conductive mating contact (not shown) such as a pin contact is inserted from the outside of the housing 5 to make electrical contact.
have. A connecting portion 9 and a holding portion 11 are continuously formed on one side of the socket portion 7 in the longitudinal direction. A core wire of the cable 1 drawn into the interior of the housing 5 is connected to the connecting portion 9. The covering portion of the cable 1 is held in the holding portion 11 .

Further, a lance 13 cut downward is formed on the bottom surface of the socket portion 7.

On the other hand, the housing 5 is formed with an accommodation hole 15 for accommodating the contact. A closing wall 17 is formed on one side of the housing 5 so as to close one side of the accommodation hole 15. A guide hole 19 is formed in the closing wall 17 to guide insertion of a mating contact. A penetrating locking hole 23 for locking the lance 13 of the socket portion 7 is formed in the bottom surface portion 21 of the housing 5. The contact 3 is inserted into the accommodation hole 15 of the housing 5 from the opening on the opposite side of the closing wall 17 with the socket portion 7 facing forward.

Since the lance 13 of the socket portion 7 of the contact 3 inserted into the housing 5 is locked in the locking hole 23 of the housing 5, the contact 3 is prevented from coming off.

Furthermore, in this cable connector, an opening 25 is formed in the upper surface of the housing 5. This opening 25 is provided with a locking piece 28 having a swinging portion 27 made thin at one end.
The swinging part 27 is connected to the housing 5, and the locking piece 28 can be rotated around the swinging part 27. A locking protrusion 30 is formed at the other end of the locking piece 28 . The locking protrusion 30 engages with the contact 3 and prevents it from coming off.

In such a cable connector, the locking hole 23 of the housing 5 and the lance 13 of the contact 3 primarily prevent the contact from coming off. Furthermore, this contact is also locked by the locking protrusion 30 of the locking piece 28, thereby secondarily preventing the contact 3 from coming off in the direction opposite to the insertion direction.

[Problem that the invention attempts to solve]

However, the housing 5 has a thin swinging section 2.
In order to provide the locking piece 28 having the number 7, the material of the housing 5 must be limited to a soft material, or the mold structure for molding the housing 5 must be complicated.
