Abstract

The utility model discloses a structure for enhancing the electro-static discharge of a folder phone, which comprises a rotating shaft, a spring piece and a conductive strip. One end of the spring piece is communicated with the main ground of a main board while the other end is in contact with the rotating shaft; the rotating shaft is arranged in a rotating hole of an upper rear cover; and the conductive strip winds around the rotating shaft and then is inserted into the rotating hole of the upper rear cover and pasted to the sub-board of the phone. The structure for enhancing the electro-static discharge of a folder phone aims to overcome the defects in the prior art and is characterized in that the sub-board ground is communicated with the main board ground so as to increase the effective area of a PCB, thereby discharging the static on the main board or sub-board, protecting the chip of the main board and effectively improving the ESD performance of the phone.

Description

A kind of structure that strengthens the release of clamshell phone static

Technical field:

The utility model technology relates to a kind of mobile communication product, and in particular, it relates to a kind of structure that clamshell phone static discharges that strengthens.

Background technology:

Mobile phone is as a kind of communication tool, become indispensable requirement in people's daily life, especially populous, the China of economic civilization fast development, mobile phone technique has been obtained significant progress, constantly develops the various technology that can be applied to mobile phone.The today of making rapid progress; the appearance design of mobile phone is also more and more of all shapes and colors; various surface decoration techniques; new material constantly is applied in the middle of the mobile phones design; some five metals decorations particularly; as aluminium flake; steel disc; the nickel sheet; often used in the material mobile phone appearance designs such as electroplated decoration part; ESD performance to mobile phone causes very big challenge; particularly present technique relates to clamshell phone; because of the mainboard area less; it is too many that decoration uses; be the main cause that often causes ESD fail, the anti-ESD design of present mainboard mainly is to arrange the transient voltage inhibitor to avoid impacting with the protection chipset in circuit.

The utility model content:

Technical problem to be solved in the utility model will overcome the deficiencies in the prior art exactly, provides a kind of simple in structure, is easy to processing and manufacturing, and good a kind of of result of use strengthens the structure that clamshell phone prevents static.

A kind of structure that strengthens the release of clamshell phone static, comprise being communicated with Coupling Shaft, spring leaf, bus, the ground on described spring leaf one end and the mainboard is connected, and the other end contacts with the connection Coupling Shaft, described connection Coupling Shaft is installed in the drain pan shaft hole, and joins by bus and mobile phone subplate.Described connection Coupling Shaft is installed in the drain pan rotating shaft, and described bus inserts in the drain pan shaft hole and is attached on the mobile phone subplate.

Described connection Coupling Shaft inside is conducting.

Described bus inserts in the drain pan shaft hole and is communicated with Coupling Shaft and joins, and twines and be communicated with one week of Coupling Shaft, and the while is most all around axis hole.

At present the deficiencies in the prior art; a kind ofly strengthen the structure that clamshell phone static discharges according to what above technical scheme was designed; subplate ground and mainboard ground are realized being communicated with; strengthen the effective area of PCB; thereby consume the static on mainboard or the subplate; reach protection mainboard chip, effectively improve the purpose of complete machine ESD performance.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model schematic diagram.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

The utility model does not have good mainly above the mainboard for what the ground that solves general mobile phone platelet was done, thus cause liding machine FLIP partly the poor problem of ESD performance and adopt as shown in Figure 1 a kind of structure that strengthens the release of clamshell phone static.

With reference to Fig. 1, a kind of structure that strengthens the release of clamshell phone static that the utility model provides, comprise spring leaf 2, rotating shaft 4, bus 6, connecting on spring leaf 2 one ends and the mainboard 3 mainly, the other end contacts with rotating shaft 4, rotating shaft 4 is installed in the shaft hole 701 of back cover 7, and, after 4 one weeks of 6 twisting shafts bus 6 is attached on the mobile phone subplate 5 with bus.

Based on above-mentioned principle, the utility model specific design is as follows:

At first with spring leaf 2 hot melts on mobile phone drain pan 1, then bus 6 is inserted in the shaft hole 701 of going up back cover 7, and ring shaft hole 701 is around big half cycle, simultaneously rotating shaft 4 is pressed in the shaft hole 701 of back cover 7, make bus 4 one weeks of 6 twisting shafts, with drain pan 1,7 assemblings of last back cover and mainboard 3, subplate 5 assemblings, at last button 8, battery cover 9, following back cover 10, upper end are renovated other structure accessories such as shell 11, eyeglass 12 and assembled again.

Mobile phone by above design is made can not have any impact to the folding angle of renovating of mobile phone, and mobile phone can rotate freely in the folding scope, need not to increase other special parts.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. one kind strengthens the structure that clamshell phone static discharges, it is characterized in that comprising rotating shaft, spring leaf, bus, the connecting of described spring leaf one end and mainboard mainly, the other end contacts with rotating shaft, described rotating shaft is installed in the shaft hole of back cover, and joins by the ground of bus and mobile phone subplate.

2. a kind of structure that clamshell phone static discharges that strengthens according to claim 1 is characterized in that described rotating shaft inside is conducting.
