Description

Bent needle seat for primary insert

Technical Field

The utility model relates to a needle seat.

Background

The PCB needle stand is a needle stand welded with the PCB. The existing PCB needle stand has the following defects: 1. the pin welding part extending out of the plastic seat is easy to deform in the assembling, transporting and using processes, so that the pin welding part is difficult to butt with the PCB; 2. through the thin positioning column and the positioning hole on the PCB board for inserting positioning, the needle seat is easy to loosen after long-term insertion and extraction. In order to solve the above problems, the applicant has proposed an application of the chinese utility model patent with the publication number "CN 208637634U" and the name "PCB needle seat with positioning function", and sets a positioning clip strip on the welding portion of the "L" shaped contact pin for improving the flatness and firmness of the welding portion of the "L" shaped contact pin. But there are also disadvantages: 1. the positioning clamping strips need to be subjected to single and independent injection molding and assembly, so that the production cost is increased; 2. resulting in a large and complicated overall structure.

Detailed Description

Referring to fig. 1-4, the primary insert curved needle seat of the present invention comprises a plastic shell 1 and three L-shaped contact pins 2 arranged in the plastic shell 1. The rear end of the plastic shell 1 is integrally formed with a convex insert seat 3, and a bending part 4 of the L-shaped contact pin 2 is embedded and molded in the insert seat 3. The plug-in part 5 at the front end of the L-shaped pin 2 is horizontally arranged in the plug-in cavity 6 of the plastic shell 1, and the welding part 7 at the rear end of the L-shaped pin 2 extends out of the bottom of the embedded part seat 3.

Preferably, the rear end of the plastic shell 1 corresponds to the two ends of the embedded part seat 3 and extends to form an installation part 8, and the bottom of the installation part 8 is integrally formed with a riveting column 9. During assembly, the riveting column 9 is riveted on the PCB to play a role in integrally supporting and fixing the insert bent needle seat, so that the stability of connection between the L-shaped contact pin 2 and the PCB is improved.

Preferably, an anti-misplug groove 10 is formed in one side of the plug cavity 6 of the plastic shell 1, and an anti-misplug matched with the plug is arranged on the plug matched with the anti-misplug groove, so that the L-shaped contact pin is prevented from being deformed due to reverse insertion of the plug.

Preferably, the upper end of the insertion cavity 6 of the plastic shell 1 is provided with a hook 11, and after the plastic shell is inserted into a plug, the hook 11 is hung in an elastic locking groove of the plug to play a role in locking. The inner wall of the plug cavity 6 corresponds to the positioning groove 12 formed in the rear of the hook 11, and the plug which is connected with the plug is provided with a first positioning groove, so that the plug is more stable after connection.

Preferably, the lower end of the plug cavity 6 of the plastic shell 1 is provided with a positioning port 13, and a plug inserted into the plug is provided with a second positioning groove matched with the plug in positioning, so that the plug is more stable after being inserted.
