[ background art ]

The existing external antenna and ultrasonic welding structure cannot guarantee that 100% of welded products meet the performance requirements of dustproof and waterproof (IP68) due to the limitation of the ultrasonic welding line structure, so that the phenomenon of water leakage and water inflow easily occurs in the external use process of the antenna, the service life of the antenna is shortened, and more serious safety accidents can be caused. The new waterproof structure design well solves the problems.

[ summary of the invention ]

The invention aims to overcome the defects in the prior art and provides an antenna structure with a novel dustproof and waterproof structure.

In order to realize the above purpose, design a novel dustproof and waterproof structure's antenna structure, a serial communication port, including antenna case, antenna body, be equipped with C type recess between the inside wall of antenna case and antenna body's lateral wall, be equipped with C type sealing washer in the C type recess, the inboard recess clearance of filling antenna case is opened under the effort to C type sealing washer lateral wall and is made the antenna inside and outside isolated, and the outside O type sealing washer of cooperation antenna body realizes inside and outside double-deck sealed.

The bottom of C type recess keeps the parallel and level with the bottom of C type sealing washer after the assembly, and the top of C type recess is higher than C type sealing washer bottom 0.2 mm.

And a C-shaped angle is arranged at the opening at the top of the C-shaped sealing ring and used for guiding.

A storage tank is arranged below a C-shaped angle of the C-shaped sealing ring, a small amount of dust and water drops are stored, when the water amount or the dust reaches a certain amount, the outer wall of the rubber ring is expanded under the action of gravity, but under the support of a groove in the inner side of the shell, the sealing performance is better, and under the action of internal atmospheric pressure, the water drops or the dust flowing into the storage tank exceed the storage tank automatically overflows.

The internal antenna routing of the antenna shell uses spiral laser lines.

The top of radium-shine antenna is established and is fixed with the PCB board, the PCB board loops through connecting female head, copper jump ring and connecting public head and links to each other with the antenna main part.

The invention has the following advantages:

1. the new structure improvement of the shell and the main body and the use of the C-shaped sealing ring enable the product to reach IP68 performance.

2. The novel C-shaped sealing ring structure design and principle enable the antenna to have dustproof and waterproof performance in an external leakage environment.

3. The spiral laser line technology is added, so that the problems of manpower waste and poor warping caused by PFC are solved.

Description of the drawings

1. The antenna comprises an antenna shell 2, an antenna body 3, a C-shaped sealing ring 4, a cylindrical spiral laser antenna 5, a connecting male head 6, a copper clamp spring 7, a connecting female head 8, a PCB 9, an O-shaped sealing ring 10, an ultrasonic bonding wire 11, a C-shaped angle 12 of the C-shaped sealing ring and a water storage tank of the C-shaped sealing ring.

[ detailed description of the invention ]

The present improvement will be further described with reference to the accompanying drawings.

Refer to fig. 1 and 2, fig. 3. The external antenna according to the improved scheme mainly comprises the following components:

a C-shaped groove is added on the inner side wall of the shell, and the bottom of the groove is kept as level as possible with the bottom of the C-shaped sealing ring after assembly; the top is 0.2mm higher than the bottom of the sealing ring, so that the supporting effect of the bottom on the sealing ring is ensured, and the sealing property of the interior is also ensured. As shown in detail in fig. 1 and 2.

Simultaneously also increase C type recess at the lateral wall of main part, this recess mainly be with C type sealing washer cooperation assembly effect, make the sealing washer hold tightly main part recess inside wall, reach the sealed effect of tight fit. Detailed description of the preferred embodiment is shown in FIGS. 1 and 2

As shown in fig. 5, after the integral assembly, the side wall of the C-shaped sealing ring is opened to fill the gap of the groove on the inner side of the housing, the inside and the outside of the antenna are isolated under the action of the C-shaped sealing ring, and the double-layer sealing effect is realized under the coordination of the external O-ring; the dustproof and waterproof are thoroughly solved. Detailed description of the preferred embodiment is shown in FIGS. 1 and 2

The structural design principle of the C-shaped sealing ring (made of butadiene-acrylonitrile rubber) plays a crucial role: the C-shaped appearance structure increases the holding force of the sealing ring. 2. The structural design of the C angle of the lip part plays a role in guiding; see figure 3, structure 11 in detail. 3. The storage tank is structurally designed, a small amount of dust and water drops can be stored, when the water amount or the dust reaches a certain amount, the outer wall of the rubber ring can be expanded under the action of gravity, but under the support of the groove on the inner side of the shell, the sealing performance is better, and the water drops or the dust flowing into the storage tank exceed the storage tank automatically overflow under the action of internal atmospheric pressure; see the 11 th structure of fig. 3a, 3b in detail.
