CN-224218579-U - Fisheye stitch pressure equipment structure in PCBA

Abstract

The utility model provides a fish eye stitch press-fitting structure in a PCBA, which is provided with three positioning plates, positioning holes and press-fitting pads which are distributed in a U shape, so that the positioning of the PCBA can be provided, the supporting force and the restoring force can be provided for the press-fitting of the PCBA, and the circuit board can be prevented from being damaged in the press-fitting process due to the fact that the PCBA cannot be perfectly coupled with the fish eye stitch due to inaccurate positioning, and the PCBA can be prevented from being damaged due to overlarge press-fitting force.

Description

Fisheye stitch pressure equipment structure in PCBA Technical Field The utility model belongs to the technical field of PCBA processing, and particularly relates to a fish eye stitch press-fitting structure in PCBA. Background The fisheye pin press fitting in PCBA is a connection process in which elastic or solid pin pins are pressed into PCB metallization holes to form mechanical connections and electrical interconnections, which has been widely used in PCBA in various fields. Under the condition that the positioning of the pressing plate in the existing pressing structure is not in place, the PCBA cannot be perfectly coupled with the fish eye pins so as to damage the circuit board in the pressing process, the PCBA is easily damaged when the pressing force of the pressing plate in the pressing structure is overlarge, and the risk of increasing the defective rate is caused, so that the utility model provides the fish eye pin pressing structure in the PCBA to solve the problems. Disclosure of utility model The utility model provides a fish eye stitch press-fitting structure in a PCBA (printed circuit board assembly), and aims to solve the problem set forth in the background technology. The utility model is realized in such a way that the fish eye stitch press-fitting structure in the PCBA comprises a press-fitting plate and a PCBA plate; The top surface of the pressing plate is provided with three U-shaped positioning plates, the three positioning plates are used for positioning three sides of the PCBA plate, positioning holes are further formed in the upper portion of the positioning plates, three pressing pads are arranged among the three positioning plates, one pressing pad is close to the positioning plate on the left side, one pressing pad is close to the positioning plate on the right side, one pressing pad is close to the positioning plate on the lower side, and the pressing pad has elastic force; the PCBA board is arranged at the top of the pressing plate. Preferably, the pressing plate further comprises four bolt fixing holes distributed in a matrix, and the pressing plate penetrates through the bolt fixing holes through bolts to be connected with the pressing equipment. Preferably, the PCBA board is provided with a plurality of mounting holes, and the mounting holes are coaxial with the positioning holes during press fitting of the fish eye pins in the PCBA board. Preferably, the press-fit pad is a press-fit pressure point of the PCBA board. Preferably, the press-fit pad is a rubber pad. Compared with the prior art, the utility model has the beneficial effects that: The press-mounting structure is provided with the three U-shaped positioning plates, the positioning holes and the press-mounting pads, so that the positioning can be provided for press-mounting of the PCBA, supporting force and restoring force can be provided for press-mounting of the PCBA, and the problem that the PCBA cannot be perfectly coupled with the fish-eye pins due to inaccurate positioning, so that the circuit board is damaged in the press-mounting process is avoided, and the PCBA is prevented from being damaged due to overlarge press-mounting force is avoided.
