Description

Easy lock and unlock connector{EASY TO LOCK AND EASY UNLOCK CONNECTOR}

The present invention presents a simple locking and unlocking connector belonging to the connector area.

Traditional self-latch locking connectors cannot effectively reduce the thickness due to the design of the self-latch locking structure. Therefore, it cannot be effectively used in situations that require ultra-thin applications, such as the frame body of an ultra-thin laptop computer.

See also FIGS. 4A to 4C which show the insulator of FIG. 1 in detail. Figure 4a is a view looking down at the insulator of Figure 1 from above, Figure 4b is a view of the insulator of Figure 1 seen from behind, and Figure 4c is a view of the insulator of the present invention seen from the side.

The insulator 14 is combined with the housing 12 to form a holding space (SP), into which the flexible flat cable 2 can be installed.

The insulator 14 has a second body 142, a support block 144, an action groove 146, a second snap fastening member 148, and a fourth snap fastening member 1410. Here, the quantity of the support block 144, the working groove 146, and the fourth snap fixing member 1410 is explained by taking two each as an example.

The second body 142 forms a support block 144, an action groove 146, a second snap fastening member 148, and a fourth snap fastening member 1410.

The support block 144 is installed corresponding to the support portion 1242. The action groove 146 is installed to correspond to the locking member 124, and the locking member 124 enters the holding space SP through the action groove 146. The second snap fixing member 148 is formed on one side of the second main body 142 and is installed to correspond to the first snap fixing member 126. In this embodiment, the second snap fastening member 148 is described as a protruding block as an example. This is used to engage the first snap retaining member 126 with an opening to allow the housing 12 to be positioned in the It prevents movement in the Z-axis direction of 4b.

The fourth snap fixing member 1410 is formed on the other side of the second main body 142 and is installed to correspond to the third snap fixing member 128. In this embodiment, the fourth snap fixing member 1210 is explained by taking a stopper groove as an example. By bending the third snap fixing member 128 in the form of a stopper gasket into the stopper groove, the housing 12 is limited by the positions of the third snap fixing member 128 and the fourth snap fixing member 1410, so that it is aligned in the XY plane of FIG. 4A. Or, it prevents movement in the Z-axis direction of FIG. 4b.

In another embodiment, the second body 142 has a stopper block 1412. The stopper block 1412 is installed to correspond to the stopper gasket 1214, and the housing is snap-fastened to the insulator by installing the stopper block 1412 on the stopper gasket 1214.

In another embodiment, the second body 142 has a positioning notch 1414. The position fixing notch 1414 is installed to correspond to the position fixing member 1216, and the housing 12 is fixed to the insulator 14 by installing the position fixing member 1216 on the position fixing notch 1414. It allows the combination to proceed conveniently.

The housing 12 is positioned on the insulator 14 through the first snap fixing member 126, the third snap fixing member 128, the second snap fixing member 149, and the fourth snap fixing member 1410.
