[0026] The present invention is described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0027] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

[0028] Example 1

[0029] like Figure 1-6 As shown, a die-cast vibrator fixing clamp which is easy to assemble is used to install the die-cast vibrator 6 on the reflecting plate 5. The front side of the die-cast vibrator fixing clamp passes through the reflecting plate 5 and is then assembled with the die-cast vibrator 6. The back side of the die-cast vibrator fixing clamp is provided with a welding clamp for installing cables.

[0030] The die-cast vibrator fixing fixture provided in this embodiment includes a fixed base surface, which includes a first surface 1 and a second surface 2 located on the front side and a third surface 3 and a fourth surface 4 located on the back side. The first surface 1 is connected to the die-cast vibrator 6, the second surface 2 is connected to the reflective plate 5, and the fourth surface 4 is connected to the cable.

[0031] The first surface 1 includes a positioning hole 11, an installation elastic member 12 and a surrounding fence 13, wherein the positioning hole 11 and the installation elastic member 12 are arranged in the surrounding fence 13, the surrounding fence 13 is used to limit the die-cast vibrator 6 to ensure that the die-cast vibrator 6 will not be skewed, and reinforcing ribs 131, U-shaped grooves 132 and triangular bosses 133 are designed on the surrounding fence 13. Four reinforcing ribs 131 are provided, which are evenly distributed at the four corners of the surrounding fence 13, and four U-shaped grooves 132 are provided, which are symmetrically arranged in pairs. A U-shaped groove 132 is provided between every two reinforcing ribs 131, and a triangular boss 133 is provided on the side of each U-shaped groove 132 facing the inner side of the surrounding fence 13. After the die-cast vibrator 6 is inserted downward into the first surface 1, the side wall of the die-cast vibrator 6 moves downward along the triangular inclined surface of the triangular boss 133, and the triangular boss 133 deforms outward. When it reaches the limit point designed for the die-cast vibrator 6, it deforms to the maximum value and then returns to its original position. In addition, an elastic part is designed below, and the two limit the longitudinal direction of the die-cast vibrator 6; at the same time, the two positioning holes 11 on the first surface 1 also cooperate with the positioning pins 61 on the die-cast vibrator 6, and the limitation of the die-cast vibrator 6 is strengthened by the concentric cooperation of the hole and the pin; by designing reinforcing ribs 131 on the surrounding fence 13, the strength of the clamp is strengthened, and the vibrator limit is tighter through interference fit and elastic deformation of the clamp, and no tilting occurs.

[0032] The second surface 2 includes two positioning pins 21, two trapezoidal bosses 22 and two limiting buckles 23. The two positioning pins 21 are arranged diagonally, and the two limiting buckles 23 are arranged diagonally. The two trapezoidal bosses 22 are symmetrically arranged on the opposite sides of the surrounding fence 13. Each trapezoidal boss 22 is located between a positioning pin 21 and a limiting buckle 23. Each limiting buckle 23 includes a U-shaped pad 231 and a buckle body 232. The U-shaped pad 231 installed at the bottom of the buckle body 232 is deformable. During installation, the buckle limit is made tighter by squeezing the reflector 5.

[0033] The fourth surface 4 is designed with several welding clamps for installing different cables. The number and size of the welding clamps are determined according to the number and diameter of the outgoing cables designed for the vibrator, so as to facilitate welding of various commonly used types of cables thereto.

[0034] Preferably, two welding clamps I41 and welding clamps II42 are designed on the fourth surface of this embodiment to cope with different types of coaxial cables. There are two welding clamps I41, which are arranged face to face, and there are two groups of welding clamps II42, and the two welding clamps II42 in each group are arranged face to face.

[0035] A center hole 53 that is compatible with the surrounding fence 13 is opened at the central position of the reflector 5, and a positioning hole 51 that is compatible with the positioning pin 21 and a limiting card hole 52 that is compatible with the limiting buckle 23 are opened on the periphery of the center hole 53. There are two positioning holes 51, and each positioning hole 51 corresponds to a position of a positioning pin 21 one by one. There are two limiting card holes 52, and each limiting card hole 52 corresponds to a position of a limiting buckle 23 one by one.

[0036] The die-cast vibrator 6 is installed on the reflector 5 through the aforementioned die-cast vibrator fixing fixture, and the installation process is as follows:

[0037] The reflector 5 is placed above the die-cast vibrator fixing fixture, and the die-cast vibrator fixing fixture is installed upward along the vertical direction of the first surface 1. In order to limit the reflector 5 and the die-cast vibrator fixing fixture in the horizontal direction, the surrounding fence 13 needs to be aligned with the central hole 53 opened on the reflector 5, the positioning pin 21 needs to be aligned with the positioning hole 51 opened on the reflector 5, and the limiting buckle 23 needs to be aligned with the limiting clamp hole 52 opened on the reflector 5, and the limiting is completed through the cooperation between the hole and the die-cast vibrator fixing fixture, thereby completing the fixed installation of the die-cast vibrator fixing fixture and the reflector 5. During the installation process, the limiting clamp hole 52 will first squeeze the buckle body 232 to shrink it inwards, and then continue to install upwards. The buckle body 232 passes through the limiting clamp hole 52, and the deformation ends, and returns to the original position; at the same time, the U-shaped pad 231 at the bottom of the limiting clamp 23 is also squeezed by the limiting clamp hole 52 to form a deformation, giving the reflector 5 a force in the opposite direction of the deformation, so that the reflector 5 and the die-cast vibrator fixing clamp can be limited in the vertical direction;

[0038] Continue to install the die-cast vibrator 6: install the die-cast vibrator 6 downward along the vertical direction of the first surface 1, wherein the outer wall 63 of the die-cast vibrator 6 first contacts the surrounding fence 13, and in the process of downward installation, the outer wall 63 gradually contacts the reinforcing rib 131, and the fit becomes tighter and tighter. As the die-cast vibrator 6 is installed downward, the bottom of the installation groove 62 of the die-cast vibrator 6 contacts the triangular boss 133, which causes the triangular boss 133 to elastically deform outward. When the die-cast vibrator 6 sinks to the bottom edge of the triangular boss 133, or when the bottom of the triangular boss 133 exceeds the installation surface of the installation groove 62, the elastic deformation is eliminated, and the die-cast vibrator 6 is limited in the vertical direction. The positioning pin 61 of the die-cast vibrator 6 is concentrically matched with the positioning hole 11, and the interference fit of the outer wall 63 with the surrounding fence 13 and its reinforcing rib 131 limits the horizontal direction.

[0039] Continue to install the cables: install screws on the third surface 3 to strengthen the fixation of the die-cast vibrator fixing clamp and the die-cast vibrator 6; coaxial cables 7 of different diameters are respectively inserted into the corresponding welding clamps Ⅰ41 and welding clamps Ⅱ42, and cooperate with the corresponding welding points 65 on the die-cast vibrator 6, weld the outer conductor of the coaxial cable 7, and finally weld the inner conductor of the coaxial cable 7 to the feeding plate 64 of the die-cast vibrator 6 to complete the installation of the feeding network, and obtain the following Figure 6 The product structure shown in the figure can directly fix cables of various diameters, making welding easier and enhancing reliability.

[0040] Compared with the existing installation scheme that requires manual installation of screws, plastic sleeves, plastic gaskets, etc. to complete the insulation of the screws to the reflector, and the installation of the plastic base and the vibrator to complete the insulation of the vibrator to the reflector, the utility model only needs to simply install a die-cast vibrator fixing clip to complete the functions of the above-mentioned parts, which is more convenient to install and more efficient.

[0041] Parts or structures not specifically described in the present invention may adopt existing technologies or existing products and will not be described in detail here.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
