Description

Technical Field

[0001] The utility model relates to the technical field of circuit connectors, and more specifically to a horizontal patch needle seat of a circuit board connector. Background Art

[0002] In common electronic devices, there are a large number of electronic components, which are generally connected and operated through PCB circuit boards. The SMD pin holder is an electrical connector that is electrically connected to the PCB board by welding and is used to plug into the male connector plug. It is a more popular process technology today.

[0003] Two independent connecting plates are provided on the common patch needle holder for welding with the circuit board to fix the needle holder. Most common connecting plates are vertically inserted into the needle holder. This fixing method has limited fixing effect and is prone to loosening in the vertical direction, resulting in low connection strength between the needle holder and the circuit board, which cannot ensure the stability of the equipment during long-term use. Moreover, the common needle holder body and the plug-in pins are independently provided and then combined together. Generally, the plug-in pins are directly inserted into the body of the holder and fixed by their own friction effect. There is a lack of positioning structure, and the connection is not tight enough. During use, the plug-in pins may shake on the body of the holder, affecting the connection effect. In addition, common patch needle holders can be divided into horizontal or vertical patch needle holders, among which the horizontal patch needle holder can be connected to the plug of the male connector from the side. If the connector is aligned with the needle holder during combination, the column may cause damage to the needle tip and bending, affecting the use of the equipment. Utility Model Content
