Description

Detailed Description of the Invention

[0001]

The present invention relates to a first connector and a second connector.
Connector consisting of a combination of
Regarding an external interface connector used for various electronic devices such as a modem card and a mobile phone, a serial connector, etc., more specifically, even when the first connector and the second connector having different numbers of cores are connected The present invention relates to a connector capable of engaging and locking both connectors with each other.

[0002]

2. Description of the Related Art In the conventional connector of this type, the first
Of the connector, for example, the card-side connector, and the second connector, for example, the cable-side connector, have a withdrawal force (engagement holding force). It was the sum of the numerical value multiplied by and the locking force of the side lock arms and side latches provided on both sides of the housing (insulator). That is, in the above-described conventional connector, in addition to the holding force by the contacts, as a measure to improve this holding force, a mold-integrated locking mechanism that restricts the movement of the contacts in the pitch direction is provided at both ends of the insulators. ing.

[0003]

However, in the above-mentioned conventional connector, for example, the card side connector 7 and the cable side connector 8 as shown in FIG. 6 have different numbers of cores (the one shown in FIG. 6 is Number of concentric cores)
When these are fitted and connected, the side lock arm acts only on one side latch of one connector. When the side lock arm acts on only one side in this way, the engagement holding force by the side lock arm becomes half the force when the side lock arm acts on the side latches on both sides, and the engagement of the entire connector The holding force is reduced and the connector easily comes off.

The present invention was developed by paying attention to the drawbacks of the conventional connectors as described above. Even when the number of cores is different between the first connector and the second connector, the engagement between both connectors is performed. It is intended to provide a connector having a strong holding force.

[0005]

According to the present invention, a first connector having a substantially box-shaped first insulator and a first contact disposed in the first insulator along a predetermined direction. And a second connector fitted into the first insulator, and a second connector having a second contact arranged in the second insulator along the predetermined direction and in contact with the first contact. A side lock arm is provided at both ends of one end of the first insulator in the predetermined direction and both ends of the second insulator in the predetermined direction.
A connector in which a side latch that engages with the side lock arm is provided at both ends of the other end of the connector,
An auxiliary lock arm is provided on one of the portions of the insulator parallel to the predetermined direction and one of the portions of the second insulator parallel to the predetermined direction, the auxiliary lock arm being provided on the other portion parallel to the predetermined direction. A connector is obtained which is provided with an auxiliary latch which engages the lock arm.

[0006]

In the connector of the present invention, the auxiliary lock arm is formed on one of the first connector and the second connector, and the auxiliary latch is provided on the other connector. Since the auxiliary lock arm is provided in the parallel portion of the one insulator in the predetermined direction, and the auxiliary latch is provided in the parallel portion of the other insulator in the predetermined direction, the number of cores of the first connector and the second connector is equal. , I.e., the widths of the first connector and the second connector are different, the auxiliary lock arm and the auxiliary latch are always engaged. Even if the number of cores is different between the first connector and the second connector, the side lock arms and the side latches respectively provided at both ends of the first and second insulators in the predetermined direction have at least one side. Can be engaged with. Therefore, even if the number of cores differs between the first connector and the second connector, the side lock arm and the side latch can be engaged on one side of both insulators, and the auxiliary lock arm and the auxiliary latch can be engaged. A sufficient engagement holding force between both connectors can be ensured.
