As an improvement the feeder line is flexible circuit board.

As a further improvement, first connector is magnet.

As an improvement the feeder line is coaxial line.

As a further improvement, first connector includes the sheet metal connecting with the coaxial line, the metal On piece is provided with magnet.

To solve above-mentioned second technical problem, the technical solution of the utility model is: a kind of wireless headset, including earphone Mainboard, the earphone mainboard are connected with radio-frequency antenna, and the radio-frequency antenna is said radio-frequency antenna, are arranged on the earphone mainboard There is the second connector compatible with the first connector of the radio-frequency antenna.

As an improvement second connector is magnet.

After above-mentioned technical proposal, the beneficial effects of the utility model are:

Plastic shell and metal insert are connected to by radio-frequency antenna and wireless headset provided by the utility model by injection molding Together, LDS antenna is compared, it is relatively low to housing requirements, it is at low cost without applying five roasting techniques by five；Due to the metal Inserts is located on the inside of the plastic shell, so that it is compact-sized, it is not take up inner space.Radio-frequency antenna provided by the utility model And wireless headset, reliable performance is stablized, not only compact-sized but also at low cost instead of existing LDS antenna.

Since the first connector is magnet, the second connector is magnet, in this way when the first connector and the second connector lean on When close, the first connector and the second connector pass through the automatic calibrating position of magnetic force and firmly suck, and ensure that the consistency of impedance, Reach the performance of antenna.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

Embodiment one

As Fig. 1 and Fig. 2 jointly shown in, a kind of radio-frequency antenna is embedding including being molded the plastic shell 1 that links together and metal Part 2, metal insert 2 are located at 1 inside of plastic shell, and metal insert 2 is connected with feeder line 3a, the first connection is provided on feeder line 3a Device.

Plastic shell 1 is tubular, closed at one end, the other end opening of plastic shell 1；Plastic cement is stretched out in 2 part of metal insert The open end of shell 1.

In the present embodiment, feeder line 3a is flexible circuit board, and the first connector is magnet 4a.

It should be noted that the connection type of feeder line 3a and metal insert 2 or the first connector can be using welding, SMT Modes such as (Surface Mounted Technology, surface mounting technologies).

In this way, plastic shell 1 and metal insert 2 are linked together by injection molding, LDS antenna is compared, to housing requirements It is relatively low, it is at low cost without applying five roasting techniques by five；Since metal insert 2 is located at 1 inside of plastic shell, so that structure It is compact, it is not take up inner space.

Embodiment two

The present embodiment is basically the same as the first embodiment, the difference is that, as Fig. 3 to Fig. 5 jointly shown in, in this implementation In example, feeder line 3b is coaxial line.

The present embodiment also discloses a kind of wireless headset, including earphone mainboard 6, and earphone mainboard 6 is connected with above-mentioned radio frequency day Line is provided with the second connector compatible with the first connector of radio-frequency antenna on earphone mainboard 6.

Wherein, earphone mainboard 6 is PCB (Printed Circuit Board, printed wiring board).

The antenna feed point of the wireless headset of the prior art is by the way of connector fastening.But this mode is due to its connection Device male connector and connector female end is too small is difficult to assemble, it is necessary to which contraposition could accurately buckle well connector male head and female, this is invisible In increase the operation difficulty of operator, reduce packaging efficiency.Simultaneously according to bad analysis, not buckled well due to connector is caused It is bad more, reduce the yield of product.In order to improve packaging efficiency, and guarantee the yield of product, in the present embodiment, the A connector includes the sheet metal 5 connecting with coaxial line, is provided with magnet 4b on sheet metal 5.Second connector is magnet 7.It is excellent Choosing, magnet 7 be the magnet after plating, magnet after plating can direct patch on earphone mainboard 6 so that the processing is simple, at This is low.

In this way when magnet 4b and magnet 7 close to when, magnet 4b and magnet 7 pass through the automatic calibrating position of magnetic force and firmly inhale Tightly, it is first aligned without operator and presses fastening afterwards, ensure that the consistency of impedance, reach the performance of antenna.

Certainly, the magnet 4a in above-described embodiment one can also pass through the automatic calibrating position of magnetic force with magnet 7 and firmly inhale Tightly.

Radio-frequency antenna and wireless headset provided by the utility model, reliable performance is stablized, instead of existing LDS antenna, It is compact-sized, it is at low cost；First connector and the second connector fasten easy to operate, packaging efficiency height, only need to be by the first connection Device is close to the second connector；High reliablity, product yield are high, it is ensured that fasten no problem.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
