Description of drawings
Fig. 1 is a main element exploded view before the preferred embodiment processing of the present invention;
Fig. 2 is the preliminary assembly drawing of Fig. 1 element;
Fig. 3 is that Fig. 2 has processed network for location.
Embodiment
As shown in Figure 1, the head end of fixed or movable to constitute (as telescopic) antenna part, its main element promptly comprises an insulating coating pipe 10, one coils 20 and a metal bearing 30.
This insulating coating pipe 10 is made for the master with the plastic cement based material, and it can be the engineering plastic that plastic cement system is mixed with rubber system or other appropriate materials.When using the engineering plastic that mixes, plastic cement based material percentage by weight preferably accounts for 40-100%.In illustrated embodiment, this outer tube 10 is provided with the interior blind hole 12 of an appropriate depth and diameter, and it forms a little length expanded hole portion 14 for constitute a concave part 16 between the two near upper shed place.20 of one spiral coils can be inserted in the interior blind hole 12 of above-mentioned outer tube 10, then the metal bearing tentatively are assembled in expanded hole portion 14 with suitable tightness.
As shown in Figure 1, 2, but this metal bearing 30 can make with any heat conductive metal, but cooperate conductivity with the copper based material for the most desirable.Though can carry out procedure of processing of the present invention as long as this metal bearing 30 connects with suitable tightness with outer tube 10, but in preferred embodiment as shown in Figure 1, this metal bearing 30 at one end face 31 is provided with the short protruded stigma 33 of central authorities, contain and cooperate outer tube 10 match the setting diameter in hole and the outer peripheral face 35 of length, and be provided with path cylinder 39 in the other end 37, for forming shoulder in this other end.According to this during as shown in Figure 2 the preliminary assembling of the made metal bearing 30 of a preferred embodiment, its outer peripheral face 35 is combined in the expanded hole portion 14 of outer tube 10 with suitable tightness sleeve, and make one end 31 be pressed against the concave part 16 of outer tube 10, be slightly larger than this expanded hole portion 14 by its outer peripheral face 35 length are preset as, make it at the in addition end face 37 of this assembled state end face 18 a little more than outer tube 10.
Yi Xia processing action for convenience of description, the outer peripheral face 35 and outer tube 10 expanded hole portions 14 junctions of above-mentioned metal bearing 30 will be called " face of weld A ", and metal bearing 30 other the formed shoulders of end face will be called " heating surface B ".
In enforcement hot melt of the present invention processing job procedure, preferably make heating surface B as far as possible near face of weld A.In the foregoing description structure,, thereby should constitute desirable heating surface B in the place because metal bearing one end, 37 formed shoulders and its outer peripheral face 35 are very close.This heating surface B not only has the transcalent advantage of low coverage, more can shorten weld time and process velocity.
One heating source (figure does not show) can be pressed against above-mentioned heating surface B and heat rapidly.Using under plastic outer tube 10 and the copper material metal bearing 30, feasible embodiment is for to carry out 200～250 ℃ to it, time is about 2～3 seconds heating rapidly, and the neighboring 35 of this metal bearing 30 will produce the welding effect and powerful interlock with the endoporus that matches of outer tube 10.
Make above-mentioned heating surface B be positioned at metal bearing 30 and outer tube 10 junctions slightly the top heat rapidly real belong to necessary, the distortion or the impaired destruction that so can effectively prevent outer tube 10.
Shown in Fig. 2,3, in the diagram preferred embodiment, when heating surface B is heated rapidly, can pressurize downwards to set stroke, make whole metal bearing 30 in the time of instantaneous welding, stretch into outer tube 10 inside, its shoulder is flushed to the most desirable with the end face 18 of outer tube 10 when locating fully.Cooperate this procedure of processing, the degree of depth of blind hole 12 can be made as the length of slightly being longer than under coil 20 normalities in the insulating coating pipe 10.
In this processing method of the present invention, when the assembling set winding, owing to carry out instantaneous welding, can finish assembling in the influence that almost is not subject to processing action in coil, so circle footpath, circle distance and total length thereof that this coil originally set all can be kept, the defective products ratio that old processing method caused can significantly be reduced, and product quality is also more stable and reliable, also rapid and convenient more during production.
Above illustrated embodiment spiritual category only of the present invention for convenience of description, know various simple and easy distortion that the dealer of this delegation done and repair erosion, all should comprise that in the claim of the present invention, the inventive method effect is significantly improved, meet each important document of patent of invention, so propose application for a patent for invention in accordance with the law.
