【Detailed ways】

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

The utility model is an improvement aimed at the existing connector joint. The shell is composed of the upper shell 1 and the lower shell 2. In order to make the shell have a longer service life and good buckling performance, the utility model The housing in the new model is made of stainless steel, and is composed of the rubber core 3, the plug pad 4, and the terminal seat 5 arranged in the above housing. The rubber core is installed in the cavity formed after the upper shell 1 and the lower shell 2 are fastened together. 3. The two sides of the rubber core 3 are respectively provided with positioning grooves 6 for fixing the plug pad 4, and the lower part of the plug pad 4 is provided with a terminal seat 5. When the plug pad 4 is installed on the rubber core through the positioning pieces 14 on both sides 3, the cable 15 glued to the lower part of the plug pad 4 is pressed and fixed between the plug pad 4 and the rubber core 3 at the same time, and the terminal contacts arranged in parallel on the terminal base 5 are also pressed together. 7. This is the copper wire in the cable 15 that has been stripped of the insulation layer, and is tightly pressed together with the terminal contact pins 7 in one-to-one correspondence, thereby forming a reliable electrical connection. In addition, the fastening of the plug pad 4 and the rubber core 3 also buckles and fixes the terminal base 5 on the rubber core 3. The terminal base 5 is provided with a plurality of parallel terminal contact pins 7, and the terminal contact pins 7 are the terminal base 5. in the terminal. In order to ensure that the copper wire in the above-mentioned cable 15 and the terminal contact pin 7 have a more accurate position, in the utility model, it is located below the part where the insulation layer of the cable is removed, and a reinforcing plate is also pasted. The width of the reinforcing plate is the same as that of the cable, and the reinforcing plate can improve the accuracy of the relative position between each line in the cable 15 and improve the precision of direct cooperation with the contact pin 7 of the terminal. Both sides of the shell are respectively provided with elastic locking pieces 8, the locking pieces 8 are U-shaped and one side of the U-shape is long, the other side is short, and the shorter side is inserted into the positioning groove in the rubber core 3 Among them, a small hook 9 is provided on the top of the longer side, and the small hook 9 protrudes from the square through hole 10 at the bottom of the rubber core 3, and when the above-mentioned connector joint is mated with the connector socket, the small hook 9 passes through the , to lock the connector plug and connector receptacle together. Through such a structural arrangement, it can ensure that the contacts are tightly connected together after the above two are mated, prevent poor contact caused by the swing of the plug, and improve the reliability of the product. There are unlocking handles 11 on both sides of the rubber core 3, and the unlocking handle 11 and the rubber core 3 are integrally formed. Of course, a card slot can also be provided on the rubber core 3, and the unlocking handle can be set by assembling. The unlocking handle 11 is connected to the longer end of the locking piece 8, and the small hook 9 on it is stretched out from the square through hole 10 at the lower end of the unlocking handle 11.
