Description

Connector assembly

Technical Field

Background

When the FPC cable is required to be electrically connected to the circuit board, it is generally required to fix an FPC connector on the circuit board by soldering, and then insert the FPC cable into the FPC connector.

In practical production, the existing FPC connector is a self-locking connector, and the problem of the self-locking connector is that the friction force between the self-locking connector and the FPC cable is large, so that when the width dimension of the FPC cable is large, the insertion force needs to be large, but the property of the FPC cable is soft and easy to deform, and therefore, the FPC cable is difficult to be inserted into the FPC connector. Especially, when mechanical equipment such as a manipulator is used for mechanical assembly operation of the FPC cable and the FPC connector, assembly failure is more likely to occur.

Therefore, improvements to the existing FPC connectors are needed to solve the problem that it is difficult to perform mechanized assembly operations at the circuit board in the prior art.

In the description of the present utility model, it will be understood that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

The present utility model will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the utility model and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the utility model.

The utility model provides a connector assembly, which is suitable for an application scene of electrically connecting an FPC (flexible printed circuit) flat cable to a circuit board, and can effectively reduce the difficulty of mechanical assembly operation at the circuit board.

Referring to fig. 1 to 4, the connector assembly includes a board side connector 2 for electrically connecting with a circuit board 1 and a wire side connector 4 for plugging with an FPC flat cable 3, wherein the wire side connector 4 and the board side connector 2 are connected in a plug-in manner.

The wire side connector 4 includes a wire side insulating base 401, a plurality of wire side terminals 402 fixed to the wire side insulating base 401, and a rotary cover plate 403 hinged to the wire side insulating base 401.

The line side terminal 402 includes a terminal main body 4023, a wiring portion 4022, and a first fitting portion 4021. The lower end of the terminal body 4023 protrudes below the wire side insulating base 401 for pluggable electrical connection with the board side connector 2. One end of the wiring portion 4022 is connected to the terminal body 4023, and the other end extends below the FPC flat cable 3. One end of the first fitting portion 4021 is connected to the terminal body 4023, and the other end is fitted into the wire side insulating base 401.

Further, a wire insertion slot 4011 into which the FPC flat cable 3 is inserted is provided in a side surface of the cable side insulating base 401. The wiring part 4022 extends into the bottom of the wiring groove 4011, and is provided with a plurality of wiring bosses 4022a protruding upwards to be abutted against the golden fingers at the bottom of the FPC flat cable 3.

Optionally, the wiring part 4022 is further provided with a second fitting part 4022b fitted inside the wire side insulating base 401.

In this embodiment, a contact surface 4031 for pushing the FPC cable 3 downward is provided on a side of the rotary cover plate 403 close to the FPC cable 3. Specifically, when the rotary cover plate 403 rotates to a horizontal state, the abutment surface 4031 presses down the FPC cable 3, so that the golden finger at the bottom of the FPC cable 3 presses down against each of the wiring bosses 4022a, at this time, the FPC cable 3 is pressed by the abutment surface 4031, and it is difficult for the user to pull out the FPC cable 3;

when the rotary cover plate 403 rotates to the vertical state, the abutting surface 4031 is separated from the FPC cable 3, and the user can easily insert or extract the FPC cable 3 into or from the differential slot without the frictional resistance provided by the abutting surface 4031, so that even if the width dimension of the FPC cable 3 is large, there is no fear that the FPC cable 3 is deformed due to the excessive insertion resistance, and finally, the problem of difficult insertion occurs.

It should be noted that, since the connection operation between the FPC cable 3 and the wire-side connector 4 can be performed in an open space, and the wire-side connector 4 has a screw cap structure, the resistance encountered when the FPC cable 3 is inserted into the wire-side connector 4 is small, and the connection and disconnection are easier, so that the difficulty in assembling the FPC cable 3 and the wire-side connector 4 is also low; after the connection between the FPC flat cable 3 and the line-side connector 4 is completed, the line-side connector 4 can be directly inserted into the board-side connector 2 using a mechanical device such as a robot.

The side of the rotary cover plate 403 is provided with a positioning boss 4032, the wire side insulating base 401 is provided with a positioning groove 4012 for the positioning boss 4032 to be clamped in, and when the rotary cover plate 403 rotates to a horizontal state, the positioning boss 4032 is clamped in the positioning groove 4012, so that the clamping state of the FPC flat cable 3 is maintained.

In this embodiment, the board-side connector 2 includes a board-side insulating base 201 and a plurality of board-side terminals 202. A terminal slot 2011 into which the lower end of each wire side terminal 402 is inserted is formed at the top of the board side insulating base 201; each board-side terminal 202 is mounted in the board-side insulating base 201.

The board-side terminal 202 includes a third embedding portion 2021 embedded in the board-side insulating base 201 and two elastic clip arms 2022 that protrude into the terminal insertion slots 2011 to clip the corresponding wire-side terminals 402.

Wherein the first fitting portion 4021 penetrates the wire side insulating base 401 and abuts against one of the elastic clip arms 2022;

the terminal body 4023 abuts the other elastic clip arm 2022 on a side away from the first fitting portion 4021.

Optionally, an abutment 2022a abutting against a side surface of the terminal body 4023 is provided on an inner side of the elastic clip arm 2022, so that the wire side terminal 402 is clamped after the lower end of the terminal body 4023 is inserted, and an anti-loosening effect is achieved.

Optionally, a hook boss 2012 is provided on a side surface of the board-side connector 2, and a hook plate 4013 that is fastened to the hook boss 2012 is provided on a side surface of the line-side connector 4. After the wire side connector 4 is inserted into the board side connector 2, the hook plate 4013 hooks the hook boss 2012 to prevent loosening.

In the connector assembly provided in this embodiment, the board-side connector 2 is fixed on the circuit board 1 by welding or other means, the rotary cover plate 403 can be opened in an open space, then the FPC flat cable 3 is inserted into the wire-side connector 4, after the rotary cover plate 403 is tightly covered, the wire-side connector 4 is inserted into the board-side connector 2 by using mechanical equipment such as a manipulator, thereby realizing mechanized assembly operation at the circuit board;

further, since the board-side connector 2 and the wire-side connector 4 are both rigid structures, even if the width dimension is large, the insertion and extraction operation can be easily performed using mechanical equipment;
