The utility model discloses, through the zigzag connection structure who sets up, intensity is higher, and fixed mode is more nimble, increases and decreases the inseparable degree of contact through the interference volume that sets up when the elastomeric element of contact shell fragment tip and PCBA board installation, and it is inseparabler to compare fixedly with traditional U type joint contact fixed mode, and the contact is better.

Description

Mobile phone charger PCBA board is with contact shell fragment

Technical Field

The utility model relates to a mobile phone charger technical field especially relates to a mobile phone charger PCBA is contact shell fragment for board.

Background

The structure of the charger is changed along with the model of the mobile phone, the charger is more and more beautiful, and the shape is more and more complex, so that a plurality of assembling problems can be encountered when the charger is assembled. For example, the PCBA board is generally an independent component, and is independently processed and manufactured before assembly, and the charger housing generally integrates plug hardware, and the hardware and the housing are glued together to achieve the purpose of stable fixation. When assembling the PCBA, the PCBA is often connected with hardware in an additional mode. At present, the U-shaped elastic part is connected in a U-shaped elastic part mode, one end of the U-shaped elastic part is connected with the plug hardware, the U-shaped part is connected with a contact on the PCBA board in an inserting mode, and actually, only one point is connected with the PCBA board, so that the other end of the U-shaped part has no function.

Disclosure of Invention

To the problem that the utility model provides, an object of the utility model is to provide a cell-phone charger PCBA contact shell fragment for board, the inseparable degree of contact is increased and decreased through the interference volume that sets up when the elastomeric element of contact shell fragment tip and PCBA board installation, realizes the purpose of adjustable elasticity volume, satisfies the demand that different PCBA boards are connected.

The technical scheme of the utility model is realized through following mode: the utility model provides a cell-phone charger PCBA contact shell fragment for board, comprises coupling part, supporting part, elastic component, coupling part, supporting part and elastic component structure as an organic whole, bend through the spring steel piece and make, coupling part be the zigzag structure, the supporting part sets up the bottom longitudinal extension end at coupling part, the elastic component set up the tip at the supporting part and through arc angle transitional coupling, the elastic component be L type structure, its characterized in that: the width of the connecting part is respectively larger than the width of the supporting part and the width of the elastic part, and the width of the supporting part is equal to that of the elastic part.

The upper plane of the Z-shaped structure of the connecting part is provided with a square hole connected and fixed with the plug hardware.

And a limiting round hole is arranged on the upper plane of the Z-shaped structure of the connecting part.

The included angle A between the supporting part and the bottom of the connecting part is an obtuse angle.

The connection included angle B between the supporting part and the elastic part is an acute angle.

And the transverse distance C between the outermost quadrant point of the elastic part and the outer side surface of the vertical connecting part of the connecting part is larger than the thickness of the PCBA.

The utility model discloses, through the zigzag connection structure who sets up, intensity is higher, and fixed mode is more nimble, increases and decreases the inseparable degree of contact through the interference volume that sets up when the elastomeric element of contact shell fragment tip and PCBA board installation, and it is inseparabler to compare fixedly with traditional U type joint contact fixed mode, and the contact is better.
