Description

Connector with automatic locking structure

This creation is the technical field of a connector, especially a connector with an automatic locking structure for latching flat wires.

The traditional wire-to-board connector is used as a connecting element for the electrical connection between the wire and the circuit board. The advantage is that it can be soldered to the circuit board without physical soldering, allowing users to easily plug and unplug. The effect of electrical connection.

In order to allow the connector and the wire to be firmly in contact, a variety of connection methods have been developed, such as automatic latching, so that the connector and the wire can be easily connected without falling off, and the aforementioned actions are in the process of inserting the wire into the connector In this case, the connector will be automatically latched to maintain the connection between the connector and the wire; however, the traditional automatic latching connector has a thicker thickness due to the complicated automatic latching structure, which is not suitable for thin application fields.

It is worth noting that, here, the shaft protrusion 162 has a plurality of inclined surfaces for inserting into the groove 128 and rotating in the groove 128. The different inclined surfaces allow the operator to know the current rotation state or limit of the cover 16 The purpose of the position, for example, different slopes can distinguish the angle of rotation. Also refer to FIG. 7, which is a schematic diagram illustrating the combination of the shaft protrusion of the cover body and the groove of the base body of the invention in FIG. 1.

In addition, in the part where the first buckle 1210 and the second buckle 164 are in contact with each other, a lead angle can be formed at the first buckle 1210, the second buckle 164, or both, which can be positioned smoothly or smoothly. Installation and other purposes.

Furthermore, the cover 16 further forms an opening 166 to accommodate the locking assembly 18 mentioned later, which can be used to eliminate the deformation generated by the locking assembly 18 without affecting the deformation of the cover 16 as well.

In addition, the cover 16 can also form a limiting structure 168 corresponding to the first side wall 122 and the second side wall 124. Here, the limiting structure 168 is illustrated with an L-shaped recessed structure as an example. The limiting structure 168 acts on the first side wall 122 and the second side wall 124 to determine the rotation range of the angle θ, that is, when the inner wall surface of the limiting structure 168 contacts the first side wall 122 and the second side wall 124, Have It is resisted by the inner wall to stop turning.

Refer to Figure 5(a) and Figure 5(b) together. Fig. 5(a) is a top view illustrating the locking assembly of Fig. 1 of the invention; and Fig. 5(b) is a cross-sectional schematic diagram illustrating the locking assembly of Fig. 1 of the invention combined with a flat wire.
