Abstract
The invention relates to a jig for mounting a power amplifier elastic clamping piece. The jig comprises a wrench and a base. The wrench comprises a handle and a pressing plate which are fixedly connected. The protrusion is disposed at the front end of the pressing plate. A guide rail part is disposed at the bottom of the base. A groove is formed in the side of the base. The protrusion at the front end of the pressing plate can be clamped into the groove in the side of the base. By the jig, the elastic clamping piece is allowed to easily and fast fix a transistor on the radiator of a power amplifier, the elastic clamping piece can be removed from the transistor fast, and time and manpower cost are saved.
Description
Technical field
The present invention relates to a kind of tool of installing for power amplifier cartridge clip sheet.
Background technology
Existing power amplifier utilizes press strip (or support) that transistor is kept flat and is fixed on the effect that can reach efficiently radiates heat on radiator conventionally, as undesirable in radiating effect, will have a strong impact on transistorized service life.But this kind of fixed form will cause radiator too wide, be unfavorable for whole power amplifier installation (because of interior space limited); And newly-designed vertical cartridge clip sheet mounting means width and the height of constriction radiator greatly makes whole power amplifier be more conducive to the installation in car.But the cartridge clip sheet adopting is quite difficult in installation, this process is time-consuming, effort, and cost is higher.
Summary of the invention
The object of the invention is to the defect for overcoming prior art, and provide a kind of power amplifier cartridge clip sheet tool more convenient to install.
For achieving the above object, the present invention by the following technical solutions: a kind of for power amplifier cartridge clip sheet install tool, comprise spanner and pedestal, described spanner comprises handle and pressing plate, handle is fixedly connected with pressing plate, described pressing plate front end is provided with a lug boss; Described base bottom is provided with a rail portion, and pedestal side is provided with a groove; The lug boss of described pressing plate front end can be connected in the groove of pedestal side.
The bottom of described pressing plate is interior concaved circular cambered surface.
The tail end of described handle is provided with square elbow.
The lug boss of described pressing plate front end is cylindrical, the circle that the groove cross section of described pedestal side is opening.
Described pedestal is cuboid, and the rail portion of described base bottom is cylindrical.
The present invention's beneficial effect is compared with prior art: 1) utilize the present invention can make cartridge clip sheet easily, efficiently transistor is fixed on radiator, save time and cost of labor; 2) utilize the present invention can efficiently cartridge clip sheet be taken off from transistor equally, save time and cost of labor.

The specific embodiment
In order to more fully understand technology contents of the present invention, below in conjunction with specific embodiment, technical scheme of the present invention is further introduced and explanation.
As shown in Figure 1 and Figure 2, a kind of tool of installing for power amplifier cartridge clip sheet, comprises spanner 10 and pedestal 20, and described spanner 10 comprises handle 11 and pressing plate 12, and handle 11 is fixedly connected with pressing plate 12, and described pressing plate 12 front ends are provided with a lug boss 121; Described pedestal 20 bottoms are provided with a rail portion 21, and pedestal 20 sides are provided with a groove 22; The lug boss 121 of described pressing plate 12 front ends can be connected in the groove 22 of pedestal 20 sides.Carrying out mini power amplifier cartridge clip sheet 40 while installing, the lug boss 121 of pressing plate 12 front ends is connected in the groove 22 of pedestal 20 sides, the rail portion 21 of pedestal 20 is slided and is located in the guide-track groove 31 of radiator 30, the compressed part of cartridge clip sheet 40 43 is placed on transistor 50, the Access Division of cartridge clip sheet 40 41 is aimed to the opening part of the cartridge clip sheet draw-in groove 32 of radiator 30, simultaneously, the bottom of pressing plate 12 is pressed on the kink 42 of cartridge clip sheet 40, press handle 11 and make its rotation, cartridge clip sheet 40 is depressed in the bottom of pressing plate 12, the Access Division 41 of cartridge clip sheet 40 is snapped in the cartridge clip sheet draw-in groove 32 of radiator 30, the compressed part 43 of cartridge clip sheet 40 is firmly pressed on transistor 50.
The angle that cartridge clip sheet draw-in groove 32 and radiator 30 carry between the plane of transistor 50 is draw-in groove oblique angle, this draw-in groove oblique angle is between 20 ° to 50 °, before installation, angle between Access Division 41 and the vertical plane of cartridge clip sheet 40 is shell fragment oblique angle, shell fragment oblique angle is less than draw-in groove oblique angle, be generally less than 20 ° to 30 °, after installation, snap in cartridge clip sheet draw-in groove cartridge clip sheet afterwards and produce distortion, the deformation force that distortion produces acts on the side of transistor 50, make transistor 50 be close to radiator 30, reach good thermolysis.Cartridge clip sheet draw-in groove 32 opening parts are provided with arc transition portion, and it plays the effect of guiding and transition, so that the Access Division of cartridge clip sheet is snapped in cartridge clip sheet draw-in groove by tool of the present invention.
In order to improve service life, the Fast Installation of cartridge clip sheet, and the deformation force of the required generation of assurance cartridge clip sheet, in the time that cartridge clip sheet thickness is 0.8-1.2mm, preferably shell fragment oblique angle is less than 5 ° to 8 °, draw-in groove oblique angle.
Concrete, the bottom of described pressing plate 12 is interior concaved circular cambered surface 122, and while being pressed on the kink 42 of cartridge clip sheet 40 in the bottom of pressing plate 12, while pressing handle 11, the force direction that is subject to of the kink 42 of cartridge clip sheet 40 is more easily connected on radiator 30 it.
Concrete, the tail end of described handle 11 is provided with square elbow 111, in the time of dismounting cartridge clip sheet 40, handle 11 tail end square elbows 111 is inserted in the square hole 60 of cartridge clip sheet 40, prizes handle 11, can easily cartridge clip sheet 40 be disassembled.
Concrete, the lug boss 121 of described pressing plate 12 front ends is cylindrical, the circle that groove 22 cross sections of described pedestal 20 sides are opening.
Concrete, described pedestal 20 is cuboid, the rail portion 21 of described pedestal 20 bottoms is cylindrical.
The above only further illustrates technology contents of the present invention with embodiment, so that reader is easier to understand, but does not represent that embodiments of the present invention only limit to this, and any technology of doing according to the present invention is extended or recreation, is all subject to protection of the present invention.
