Description

Flexible PCB Connector

【Technical field】

The utility model relates to an electric connector, in particular to a flexible circuit board connector.

【Background technique】

Please refer to Fig. 1 and Fig. 2, it is a kind of conventional flexible printed circuit board connector, and it comprises a seat body 10, a plurality of terminals 15, a pressing assembly 20; Separated into a plurality of terminal slots 12 and a connecting slot 13; the terminal 15 is provided with a pin portion 16, two side arms 17, and an elastic arm 18, the pin portion 16 protrudes from the seat body 10, and the two sides The arm 17 is pressed against the terminal slot 12, and the elastic arm 18 is provided with a contact point 19 protruding to the connection slot 13; the pressing component 20 is clamped on the seat body 10 on both sides, and it is provided with a protruding pressing piece 21, the pressing piece 21 can be plugged into the connecting groove 13 of the seat body 10.

The known design has the following disadvantages:

1. The flexible circuit board 25 is electrically connected by the pressing component 20, so both sides of the seat body 10 must be engaged with the pressing component 20, but the flexible circuit board connector is very small in size. When the number of terminals is small or the spacing is smaller, the seat body 10 will be smaller. In this way, two small components (seat body 10 and pressing assembly 20) should be designed to engage and slide with each other and make the chasing piece 21 plugged into the seat body. The connecting groove 13 of 10 is very difficult and the precision is very high, because the assembled product will have cumulative tolerances. When assembling two very small objects, high precision is required, otherwise due to the cumulative tolerances of the two cause poor assembly.

2. Since the flexible circuit board 25 is inserted into the connection groove 13 of the seat body, there is no effect of scraping off the oxide layer of the contact 19 of the terminal, and the contact 19 of the terminal is exposed to the air because it is not covered, so When it is not used for a period of time, an oxide layer will be formed, which will affect the stability of the electrical connection.

At this time, the second elastic arm 43 elastically presses the flexible circuit board 25 to make it tightly connected to the contact point 45 of the terminal to be electrically connected, and the flexible circuit board 25 is tightly positioned. ;Similarly, when the flexible printed circuit board is to be removed, the seat body 30 only needs to be pushed forward, so that the second elastic arm 43 of the terminal is against the lower surface 36, and the flexible printed circuit board 25 and the contact 45 of the connector are slack state.

From the above description, the utility model can summarize the following advantages:

1. The plastic body of the present utility model is only a single seat body 30, and does not need to be a hinged set of two components like the conventional seat body, so the utility model is very simple to manufacture. Although the utility model is otherwise There is a positioning block 50 plugged into the connecting groove 33, but this is only a simple plugging and tightening, not a clamping or pivoting rotation method, so the precision does not need to be extremely high, and it is very easy to manufacture.

2. The utility model inserts the positioning block 50 into the connection groove 33 and the contact point 45 of the terminal 40 for tight positioning, so that the contact point 45 of the terminal can be covered, so it will not be oxidized by contact with the air, so the utility model is located in the positioning block When the 50 is not taken out for use, the terminal contact 45 will not be caused to produce an oxide layer and affect the electrical connection effect.

3. The sleeve portion 37 of the base body 30 is sleeved and engaged with the fixing assembly 60 , so that the base body 30 will not be pulled out excessively and separated from the terminal 40 .

4. The base body 30 and most of the terminals 40 can be fixed by the locking block 50 , so that the base body 30 and most of the terminals 40 will not be separated when they are not welded on the circuit board.

Please refer to Fig. 11 , which is the second embodiment of the present utility model, wherein the two sides of the rear end of the seat body 30 are provided with an upwardly-opening slot 311, and the locking block 50 is also provided with an insertion part 51 and a handle part 52, the insertion The part 51 is inserted into the card slot 311 from top to bottom so as to be clamped on the rear end of the terminal 40, so that the seat body 30 and the terminal 40 can be positioned. Please refer to FIG. 12. After the utility model is welded on the circuit board 27, Taking out the locking block 50 allows the base body 30 and the terminal 40 to move relative to each other.

The specific embodiment proposed in the detailed description of the preferred embodiment is only for the ease of explaining the technical content of the present utility model, but not to limit the utility model to this embodiment in a narrow sense. In fact, the utility model can be used in various ways. Change implementation.
