Description

Cable connector {Cable connector}

The present invention relates to a connector for a cable, and more particularly, to prevent the cable from being inserted incorrectly by the closing operation of the flip when the cable is connected to the cable, and to ensure that the flip is securely locked to the insulator to prevent signal transmission failure. It relates to a cable connector.

In general, a cable connector used to connect an FPC or FFC to a printed circuit board includes an insulator fixed on the printed circuit board, a plurality of terminal contacts coupled to the insulator at the rear of the insulator and electrically connected to the printed circuit board; It consists of a flip for fixing the flexible cable to the front of the insulator to electrically connect the terminal contact and the cable.

However, the connector according to the related art has a problem in that it is difficult to couple flips at both ends of the insulator at one time, and the flip-coupled state of the insulator does not maintain the binding state and is frequently separated from both ends of the insulator.

In addition, conventionally, when the flip is closed in a state in which the flexible cable is not correctly inserted into the front of the insulator, a poor signal transmission between the printed circuit board and the cable may occur, thereby lowering the reliability of the product.

The object of the present invention devised in view of the above problems is to provide a cable connector to prevent the signal transmission failure due to assembly errors by easily verifying whether or not the position of the cable is inserted during assembly. Is in.

Another object of the present invention is to provide a connector for a cable that can be easily assembled when assembling the flip on both ends of the insulator, and to maintain the binding state of the flip in the state coupled to the insulator.

The front of the coupling portion 12 is formed with a 'b' shaped insertion groove 13 is inserted into the hold down 40, the locking projection 12a is formed on the upper side of the insertion groove (13).

In addition, the flip 20 is formed in the longitudinal direction of the pressing portion 21 for fixing the cable to the insulator 10 in the front, the rear of the pressing portion 21, the insulator 10 during the rotation of the flip 20 A plurality of passage grooves 22 are formed so as not to interfere with the terminal contacts 30 coupled to the rear of the terminal, and a rotation shaft 23 is installed at the end of the passage grooves 22. On the opposite side of the rotating shaft 23, the pressing portion 24 is formed to protrude.

And both ends of the flip 20 is formed with a rotary arm 25 is rotatably inserted into the coupling portion 12 of the insulator 10, the hinge protrusion 26 is formed on the side of the rotary arm 25 The front of the rotary arm 25 is located in the front of the insertion groove 13 formed on the front of both ends of the insulator 10 during the rotation of the flip 20 to prevent the misinsertion of the cable (27) ) Is formed. Here, the hinge protrusion 26 on the side of the rotary arm 25 is formed in a cylindrical shape, the inclined surface 26a is formed from the center of the upper surface to the side, and the locking protrusion of the insulator 10 on the front surface of the misinsertion prevention portion 27.

The order of assembling the cable connector according to the present invention configured as described above will be described with reference to FIGS. 4 to 6A and 6B.

First, in order to assemble the flip 20 to the insulator 10, as shown in FIG. 4, the hinge protrusion 26 of the flip 20 has the flip 20 facing forward from the rear of the insulator 10. ) Is pushed in such a state that it does not interfere with the coupling part 12 formed at both ends of the insulator 10. At this time, at the rear edge of the coupling portion 12 of the insulator 10, a cutout portion 12a is formed to coincide with the inclined surface 26a of the hinge protrusion 26, so that the inclined surface 26a and the insulator of the hinge protrusion 26 are formed. As the cutout portion 12a of the 10 is in surface contact, the coupling portion 12 of the insulator 10 is opened to the outside so that the coupling portion 12 of the insulator 10 is passed through the hinge protrusion 26 by an interference fit method. ) Is seated in the inner space. As such, when the hinge protrusion 26 is inserted into the inner space of the coupling portion 12 of the insulator 10, the coupling portion 12 of the insulator 10 which is opened outward is restored to its original shape, so that the flip 20 The hinge protrusion 26 is not separated from the inner space of the coupling part 12 of the insulator 10.

After inserting the hinge protrusions 26 formed at both ends of the flip 20 into the coupling portion 12 of the insulator 10, as shown in FIGS. 5A and 5B, the flip 20 is placed in front of the insulator 20. In the rotated state, the pivot contact 31 and the contact beam 32 of the terminal contact 30 are inserted inside the insulator 10 at the rear of the insulator 10 to insert the terminal contact 30 into the insulator 10. Fix it to

And finally, as shown in Figs. 6a and 6b, the hold down 40 is assembled. The assembled hold down 40 is supported by the support portion 44 of the hold down 40, the flip 20 is supported in the upward direction so that the rotary shaft 23 of the flip 20 is the terminal guide of the terminal contact ( 31a) to be fixed.

After the assembly of the connector is completed, the connector is installed on the printed circuit board by fixing the lower end of the terminal contact 30 and the contact portion 43 of the hold down 40 by welding or the like to the printed circuit board.

The operation of connecting the cable to the connector assembled and mounted on the printed circuit board will be described with reference to FIGS. 7A to 7C.

FIG. 7A illustrates a state in which the cable 100 is inserted in the front of the insulator 10. The connection part of the cable 100 is connected to the seating part 11 of the insulator 10 with the flip 20 open. Settle down.

When the flip portion 20 is rotated while the connection portion of the cable 100 is seated on the insulator 10, as shown in FIG. 7B, the flip portion 20 is formed on the opposite side of the rotation shaft 23. While pressing the upper surface of the cable 100, at the same time the contact projection 32a of the contact beam 32 provided below the terminal contact 30 elastically supports the lower surface of the cable 100. At this time, the contact protrusion 32a has two pointed contact protrusions 32a-1 and 32a-2, each of which is pointed at the end thereof, so that the contact with the foreign matter and the film generated on the surface of the cable 100 occurs. It will prevent the defect.

When the flip 20 continues to rotate so that the center axis of the flip pressing unit 24 exceeds the Y axis, the flip 20 crosses the center point of the pressing unit 24 formed in an arc shape and rides on the curved surface of the pressing unit 24. As shown in FIG. 7C, the misinsertion prevention part 27 provided at both ends of the flip 20 closes the front surface of the coupling part 12 formed at both ends of the insulator 10, as shown in FIG. 7C. Is rotated. At this time, when the cable 100 is not inserted into the seating portion 11 of the insulator 10 correctly and is not seated, the cable 100 and the flip 20 are interfering with each other, so that the flip 20 is not closed. Therefore, since the flip 20 can be rotated in the state where the cable 100 is normally inserted again, the misinsertion operation of the cable 100 is prevented.

A locking protrusion 27a is formed on an inner surface of the misinsertion prevention portion 27 of the flip 20 to engage with the locking protrusion 12a formed on the front surface of the coupling portion 12 of the insulator 10. ) Will remain locked.

As described above, the connector of the cable according to the present invention has a simple structure that the flip is rotatably coupled to the insulator and the assembly workability is improved.

In addition, the present invention regulates the closing operation of the flip by the cable that is incorrectly inserted into the insulator, thereby preventing the wrong operation of the cable, and the repulsive force of the terminal contact by maintaining the locking state with the insulator while the flip is closed There is an effect that can prevent the flip open.

The present invention also has the effect of preventing contact defects because the contact projection of the hold down is in point contact with the cable.
