Abstract
The utility model discloses a circuit board fixed structure for telephone, including a fixed base plate, the last holding tank that is used for installing the circuit board that is equipped with of fixed base plate, a plurality of fixed pins have been erect in the holding tank, the center of holding tank is equipped with a fixed screw, is equipped with the fixed screw in the fixed screw, fixed base plate is last to be equipped with the solder joint blind hole that the solder joint corresponds on a plurality of and gate boards. The utility model discloses a circuit board is installed in fixed base plate's holding tank, and the circuit board is the face contact with the contact of fixed structure, and stress disperses and the difficult circuit board that damages, and screwless's mounting means also is favorable to improving the production efficiency of telephone.
Description
Technical field
The utility model relates to wiring board techniques field, is specifically related to a kind of telephone set fixing structure for circuit board.
Background technology
Wiring board in telephone set carry signal conversion, numerous function such as information storage, the circuit, the electronic component that realize above-mentioned functions are more, cause existing telephone set area large, when being arranged in telephone set, need to adopt a large amount of screws to fix, prevent wiring board from rocking, come off and cause it malfunctioning.But the operation of installing above-mentioned screw length consuming time, has a strong impact on the shortening of telephone set production cycle, the raising of danger pendant telephone set production efficiency.In addition, the mode of screw is installed and causes screw installation position to become stress concentration point, easily damaged and affect wiring board work.
Utility model content
In view of this, the utility model discloses and a kind ofly installs simple and easy, that fixed effect is good telephone set fixing structure for circuit board.
The purpose of this utility model is achieved through the following technical solutions:
A kind of telephone set fixing structure for circuit board, comprise a fixing base, fixing base is provided with the holding tank for installing wiring board, and erectting in described holding tank has multiple steady pin; The center of described holding tank is provided with a fixing threaded hole, is provided with fixed screw in fixing threaded hole; Described fixing base is provided with multiple solder joint blind hole corresponding with solder joint on wiring board.
First wiring board is arranged in holding tank, its edge be received groove wrap up, spacing, not easily shake, come off, fixing base also has buffering effect to circuit, reduces the impact of vibrations on wiring board work.Wiring board in process of production, logicalnot circuit district can be drilled with fixed via, is directly sleeved on described steady pin during installation, can further improve the stability that wiring board is installed.Wiring board of the present utility model is arranged in the holding tank of fixing base, and the contact of wiring board and fixed structure is that face contacts, stress dispersion and be not easy damaged line plate; And without the mounting means of screw, be also conducive to the production efficiency improving telephone set.The utility model arranges solder joint blind hole especially, owing to holding the blind hole on wiring board, avoids solder joint and holding tank friction and detin.Solder joint also wraps up by solder joint blind hole simultaneously, avoids its exposure aging in atmosphere.
Further, the flexible pad of described holding tank edges cover.
Elastomeric pad can select any one existing elastomeric material to make, as rubber, silica gel etc.Being provided with of elastomeric pad is beneficial to the frictional force improving wiring board and mounting groove, prevents wiring board from sliding further.Meanwhile, elastomeric pad also has pooling feature, reduces the impact of external shock to wiring board and electronic component thereof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is profile of the present utility model.
Embodiment
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that:
Embodiment 1
The present embodiment provides a kind of telephone set fixing structure for circuit board, as Fig. 1 and Fig. 2, comprises a fixing base 1, and fixing base is provided with the holding tank 2 for installing wiring board, and erectting in described holding tank has 4 steady pins 3; The center of described holding tank is provided with a fixing threaded hole 4, is provided with fixed screw 5 in fixing threaded hole; Described fixing base is provided with multiple solder joint blind hole 6 corresponding with solder joint on wiring board.
further,the flexible pad 7 of described holding tank edges cover.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection range of the present utility model.
