Description

Flexible Circuit Board Connector

technical field

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

Background technique

The existing flexible circuit board connector has a body, a shell and several terminals fixed on the body. The shell has a rotating shaft and is rotatably mounted on the body by the rotating shaft. In this flexible circuit board connector, after the flexible circuit board is inserted into the body, the housing rotates around the rotating shaft and is locked and fixed with the body. The housing presses against the terminals to hold the flexible circuit board between the terminals and the body.

However, the rotating shaft of the housing of this kind of flexible circuit board connector needs to withstand the reaction force exerted by the terminal on the housing for a long time, and due to the limitation of the structure of the flexible circuit board connector, it is difficult to increase the size and strength of the rotating shaft of the housing, so the rotating shaft is easy to The flexible circuit board connector has a short life due to fracture due to insufficient strength.

Utility model content

The purpose of this utility model is to provide a flexible circuit board connector with prolong service life in view of the above-mentioned defects and deficiencies in the prior art.

In order to achieve the above purpose, the flexible circuit board connector provided by the utility model has a housing, a body and several terminals, the housing has side walls; the body has a base plate, and a seat protrudes upwards on both sides of the base plate. The terminals are respectively fixed on the body, and the terminals have a contact portion placed above the substrate, and the housing can be pressed against the contact portion. A clamping block protrudes from the side wall, and a card slot is provided on the side wall. The seat body has a side wall, and an abutment groove is provided on the side wall. The clamping block is clamped in the abutment groove, and the side wall A protrusion is arranged on the wall, and the protrusion is placed in the slot.

As mentioned above, the housing of the flexible circuit board connector of the present invention is replaced by a snap-in block that can slide in along the abutment groove and be held in the abutment slot instead of the rotating shaft in the prior art. The size of the flexible circuit board can be increased, so that the strength can be increased, and the situation of breaking due to insufficient strength can be avoided, so that the flexible circuit board can be better locked and the service life of the flexible circuit board connector can be extended.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the flexible circuit board connector 1 of the present invention includes a housing 11 , a body 12 , two terminals 20 held on the body 12 and two soldering lugs 30 .

Please refer to FIG. 2 , the housing 11 is made of plastic material, and has two oppositely disposed side walls 111 that are roughly rectangular in shape. The side wall 111 has a top wall 113 and a bottom wall 114 opposite to each other. The top wall 113 of the two side walls 111 is connected to a top plate 112 in a substantially rectangular shape. Front ends of the side walls 111 define a locking slot 115 penetrating through the side walls 111 and extending to the bottom wall 114 , and a rectangular locking block 116 protrudes from the inner side walls of the side walls 111 .

2 and 3, the body 12 has a rectangular plate-shaped substrate 120, the rear end of the substrate 120 protrudes upwards with a substantially cuboid-shaped base 121, the base 121 has a front wall 122, a On the rear wall 123 opposite to the wall 122 , two fastening grooves 124 penetrating through the front wall 122 and the rear wall 123 are arranged side by side on the base 121 . Two sides of the base plate 120 respectively protrude upwardly from a substantially rectangular parallelepiped seat 130 , and the seat 130 extends to the front wall 122 of the base 121 . The seat body 130 has a front wall 125 and a side wall 126 , and a solder flux groove 127 is defined inwardly from the front wall 125 on the seat body 130 . Hemispherical protrusions 128 protrude from the front ends of the two sidewalls 126 , and an abutting groove 129 is formed on the seat body 130 in the middle and lower edge of the sidewalls 126 . A recessed groove 1261 is formed on the seat body 130 at the middle of the rear end of the side wall 126 . The front end of the recessed groove 1261 communicates with the rear end of the abutting groove 129 .

Please refer to Fig. 2 and Fig. 4, the terminal 20 has a holding part 21 of a rectangular plate shape, the middle part of the front end of the holding part 21 is bent downwards and then tilted forward and upward to extend a contact part 22, the middle part of the rear end of the holding part 21 faces It is bent downward and then extended backward to form a solder tail 23 .

The terminal 20 is fixed on the body 12, the holding part 21 is placed in the fastening groove 124, the contact part 22 protrudes forward from the base 121 and is placed above the substrate 120, and the solder tail 23 extends backward from the base 121 to the body 12 . The flux sheet 30 is held in the flux groove 127 and soldered on the circuit board.

The casing 11 is placed on the body 12, and the locking block 116 slides in along the abutting groove 129 and is held in the abutting groove 129. When the protrusion 128 is completely caught in the abutting groove 115, it means that the casing 11 has Completely cover on the body 12.
