Abstract
The utility model provides a diversity amplifier for a water-proof automobile antenna, and the amplifier comprises a signal input line, a signal output line, an amplifier body, a circuit board, an O-shaped sealing ring and a cover, wherein the signal input line is connected to one end of the amplifier body; the signal output line is connected to one side of the amplifier body; the circuit board is arranged in the amplifier body; the cover is arranged above the amplifier body; the O-shaped sealing ring is arranged in the cover; the cover is connected with the amplifier body by virtue of the O-shaped sealing ring; one end of the amplifier body is provided with a screw hole; the lower end of the cover is connected with a clamping hole; and the side surface of the amplifier body is provided with clamping hook. The amplifier has the beneficial effect that moist air or liquid can be effectively prevented from entering the circuit board so as to ensure that the circuit part is still prevented from being eroded when the diversity amplifier is in a moist environment and the surrounding environment with water or other liquid is eroded, and the circuit part can normally receive an antenna signal and a processing signal.
Description
Technical field
The utility model relates to the car antenna technical field, especially relates to a kind of waterproof car antenna and divides the collection amplifier.
Background technology
In the prior art; Car antenna branch collection amplifier scarcely has functions such as waterproof, antifog, anti-badly corrosion, when therefore under adverse circumstances, perhaps special waterproof, the corrosion-resistant requirement being arranged owing to reasons such as installation sites; Existing branch collection amplifier can't effectively prevent the intrusion corrosion of water smoke; Thereby cause antenna function forfeiture or decay, can't stablize acknowledge(ment) signal, influence is used.
The utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of waterproof car antenna to divide the collection amplifier, and effectively waterproof, antifog, anticorrosion make amplifier stablize acknowledge(ment) signal.
The technical scheme of the utility model is following:
A kind of waterproof car antenna divides the collection amplifier, comprises signal input line, output line, amplifier body and circuit board, and it is characterized in that: it also comprises lid; Wherein, Signal input line is connected an end of amplifier body, and output line is connected a side of amplifier body, and circuit board is located at the inside of amplifier body; Lid is located at the top of amplifier body, and is connected with the amplifier body.
Further, be provided with the O RunddichtringO in the described lid, lid is connected with the amplifier body through the O RunddichtringO.
Further, an end of described amplifier body is provided with screw hole.
Further, the lower end of described lid is connected with hole clipping, and the side of amplifier body is provided with grab.
Compared with prior art, the beneficial effect of the utility model is, owing to adopted lid and O RunddichtringO; It is inner effectively to stop wet gas or liquid to get into circuit board; Thereby guarantee to divide the collection amplifier when humidity and surrounding enviroment have water with other liquid corrosions, circuit part still can not weather, and normally accepts aerial signal and processing signals; Owing to adopted hole clipping and grab; Sealing lid and need not to use screw has reduced cost easily, also makes installation more simple.
Description of drawings
Fig. 1 is the explosive view of the utility model;
Among the figure: 1, signal input line, 2, output line, 3, the amplifier body, 4, the O RunddichtringO, 5, lid, 6, circuit board, 7, hole clipping, 8, screw hole, 9, grab.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation: combine Fig. 1; End at amplifier body 3 connects signal input line 1; Connect output line 2 in a side of amplifier body 3,, grab 9 is set in the side of amplifier body 3 in an end of amplifier body 3 hole 8 that screws; Circuit board 6 is installed in the amplifier body 3; O RunddichtringO 4 is installed in lid 5, the hole clipping 7 corresponding with grab 9 is set in the lower end of lid 5, and lid 5 is passed through hole clipping 7 be connected with amplifier body 3 with grab 9.During use; Be connected with vehicle body through the screw hole on the amplifier body 38 and get final product; Through the pressure between amplifier body 3 and the lid 5, utilize the specific rule of its distortion in compression and each temperature range of O RunddichtringO 4 materials, in minute collection amplifier working temperature-40 ℃～+ 90 ℃ scope; O RunddichtringO 4 is all by reasonable compression; Realize that the slit is always 0 between amplifier body 3 and the lid 5, realized that steam and liquid can't get into the space that forms between amplifier body 3 and the lid 5, thereby reached the purpose of protective circuit plate 6.
Draw according to experiment, the material of lid 5 is a plastic cement material, and the material of O RunddichtringO 4 is the rubber material, and the number of screw hole 8 is 3, when the number of hole clipping 7 and grab 9 respectively is 8, and the best results of the utility model.
Need to prove above is preferred embodiment of the present invention, and is not the scope that is used for limiting requirement protection of the present invention, and every being equal to of being done on the basis of the above replaces or conversion, all belongs to the scope of the present invention's protection.
