【Background technique】

With the rapid development of electronic products, its components are developing towards the goal of small size and low cost. Since the wiring of electrical systems is generally quite complicated, connectors for flexible cables are considered to be one of the most practical and cheapest connection devices for transmitting signals. In addition, in order to facilitate the production and maintenance of electrical systems, most circuit configurations are separated by functionality, and then connected by using flexible cables. This method is also conducive to the upgrade or maintenance of the electrical system in the future. The flexible cable connector is the most common and practical method for electrical connection of different functional circuits. Flexible flat cables are widely used as connecting elements in electronic devices (such as notebook computers, computers and other digital electronic devices) to control the overall size of the electronic devices. A conventional flexible flat cable connector assembly includes an insulating body, a plurality of terminals accommodated in the insulating body, and a flexible flat cable assembled on the insulating body and electrically connected to the terminals. Generally, each flexible flat cable includes several separate flat conductors and a pair of insulating layers covering the opposite surfaces of the conductors. The front end of the conductor extending beyond the insulating layer forms a connection portion. The connection part is inserted into the insulating body and welded to the corresponding terminal. Since the flexible flat cable is relatively light and thin, it is difficult to be fixed and reliably welded to the corresponding terminal, so that the soldering point cannot achieve good quality and affect the signal transmission. In addition, the use of welding will also greatly increase the production cost, so it is very necessary to improve the structure of the above-mentioned connecting joint.

【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 3, the utility model relates to a new type of 41-pin outer buckle connector joint, a shell composed of an upper shell 1 and a lower shell 2 snapped together, and the shell set in the above shell The rubber core 3 , the plug pad 4 and the terminal seat 7 are composed, and the above rubber core 3 and the plug pad 4 are arranged in the cavity formed by the upper shell 1 and the lower shell 2 . The rubber core 3 is provided with a recessed part 6, which is used to install the terminal base 7 and the plug pad 4, and the two sides of the recessed part 6 are provided with slide grooves 8 matched with both sides of the plug pad 4, and the terminal After the seat 7 is installed in the recessed part 6 on the rubber core 3, the terminal base 7 is buckled and fixed on the rubber core 3 by using the cooperation of the plug pad 4 and the chute 8 on the rubber core 3, and the terminal base 7 is provided with a parallel arrangement. The needle-shaped pin 9 is connected to the circuit after the above-mentioned connector joint is mated with the connector socket. As shown in Figure 4 and Figure 5, the two sides of the housing are respectively provided with a locking piece 10, the locking piece 10 is U-shaped, and one side of the U-shape is long, the other side is short, and the shorter side is inserted In the positioning groove in the rubber core 3, a small hook 11 is provided on the top of the longer side, and the small hook 11 is fastened into the positioning hole on the side wall of the connector socket. After the rubber core 3 and the shell are installed, the above-mentioned lock The stop piece 10 locks the connector plug on the connector socket through the small hook 11 arranged thereon. There are unlocking handles 12 on both sides of the rubber core 3. The unlocking handle 12 is connected to the longer end of the locking plate 10. The small hook 11 on it protrudes from the through hole 13 at the lower end of the unlocking handle 12, and is connected to the connector socket. When the above-mentioned connector joint is removed, by pressing the unlocking handle 12 on the rubber core 3, the locking piece 10 can be driven to move, so that the above-mentioned small hook 11 can withdraw from the positioning hole on the connector socket, and then force can be released. The connector connector is pulled out. In order to ensure the connection strength between the wire and the connector joint, an inwardly inclined clamping piece 14 is provided at the tail ends of the upper shell 1 and the lower shell 2 . The clamping piece 14 clamps the wire through the two clamping pieces 14 when the shell is fastened on the rubber core 3 , which can prevent the wire from being damaged due to friction between the shell and the rubber core 3 .
