The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is plan view of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of elastic pressuring plate of fixedly power amplifier amplifier as shown in Figure 1-2, for the power amplifier amplifier of in-vehicle player is fixed in to external fixation device, it comprises the compressing tablet main body, this compressing tablet main body comprises the fixing part 1 be connected with external fixation device, reach elasticity and be installed with in the compressed part 2 of power amplifier amplifier end face, described fixing part 1 is connected with compressed part 2.
Main improvement of the present utility model is, by this elastic pressuring plate, can make power amplifier amplifier elasticity tighten up, and makes the power amplifier amplifier normally to use.Issuable vibrations in the motor racing process, this elastic pressuring plate can produce buffering to the vibrations of power amplifier amplifier, avoid the mechanical deterioration of vibrations to power amplifier hardware, reduced the wearing and tearing of power amplifier amplifier, and assembling hardware is easy, has shortened assembling man-hour.
Described fixing part 1 is one-body molded with compressed part 2, can directly by a spring sheet or copper sheet, bend and form, and preparation process is easy, with low cost.Certainly, under the prerequisite of the licenses such as cost, weight, position, also can adopt other Placement, such as the mechanical connections such as bolt, chemistry connection etc. are made, and material also can adopt other material to replace.
Particularly, described fixing part 1 is U-shaped groove 6 with the connection bit of compressed part 2, and a cell wall of this U-shaped groove 6 forms fixing part 1, and another cell wall of U-shaped groove 6 stretches out into compressed part 2, and this compressed part 2 is U-shaped or V-type, and its root 3 is vertically towards fixing part 1.In this example, between compressed part 2 and U-shaped groove 6, form elastic structure, it is adapted to elastic compression in conjunction with the power amplifier amplifier; Simultaneously, the material of making this elastic pressuring plate should be elastic material.
Such as: the width of described U-shaped groove 6 is greater than the width of the circuit board that described power amplifier amplifier is set, and described fixing part 1 is less than the assembling thickness of this circuit board and power amplifier amplifier to the perpendicular distance of the root 3 of compressed part 2.This type of snaps on circuit board for the notch of U-shaped groove 6, and its fixing part 1 is fixed on this elastic pressuring plate on circuit board, and the root 3 of compressed part 2 suppresses on power amplifier amplifier end face.
