Abstract
The utility model discloses an interphone antenna, comprising a plastic cement core, a spring antenna core and an antenna terminal which are coated by rubber to form one piece. The plastic cement core is embedded in an accommodating chamber of an antenna protective sleeve; an insulation rubber sleeve and a fixing screw head are successively embedded in a clamping groove of the plastic cement core; the lower end part of the antenna terminal is embedded in a sleeve covering hole of the insulation rubber sleeve; the insulation rubber sleeve is embedded in a sleeve hole of the fixing screw head. The interphone antenna is fixed to an interphone body through the screw head; the insulation rubber sleeve separates the fixing screw head and the antenna terminal. The spring core and the antenna terminal form an integrated structure with the plastic cement core in an injection moulding mode. Compared with a traditional split type structure, the interphone antenna can effectively save dispensing materials; besides, the plastic cement core can reinforce intensity of a whole interphone antenna and furthermore the whole interphone antenna is not easy to bend. Accordingly, the interphone antenna has the advantages of stable structure, long service life and good wearing property.
Description
Technical field
The utility model relates to the antenna assembly technical field, relates in particular to a kind of interphone antenna.
Background technology
As a kind of bidirectional mobile communication instrument, intercom does not have telephone expenses to produce in the situation that just can realize two-way call without any need for network support, and is applicable to relatively fix and the frequent occasion of conversation; Wherein, intercom is mainly used in the industries such as public security, civil aviaton, transportation, water conservancy, railway, manufacturing, building, service, be mainly used in contact and command scheduling between the member of community, and link up efficient and improve the quick reaction capability of processing accident in order to improve.
Important component part as intercom, interphone antenna is used for receiving and transmitting, electromagnetic wave signal between the intercom mainly receives by interphone antenna and launches, and the quality of interphone antenna is for guaranteeing that speech quality has played vital effect.
Need further point out, people are when using intercom to carry out two-way call, because operate miss is easy to meandered antenna, and then causes antenna core to be easy to lose, and finally cause the variation of antenna factor, thereby have a strong impact on the product communication effect.
The utility model content
The purpose of this utility model is to provide a kind of interphone antenna for the deficiencies in the prior art, and this interphone antenna Stability Analysis of Structures, long service life and durability are good.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of interphone antenna, include encapsulate in plastic core, the spring antenna core of one and the antenna terminal that is positioned at the bottom of plastic core, plastic core is fitted with the antenna protection cover, the core of antenna protection cover forms the containing cavity that Open Side Down, and plastic core is flush-mounted in the containing cavity of antenna protection cover; The lower surface of plastic core forms card holding trough, be embedded with successively insulating gum cover and fixed screw head in the card holding trough, the core of insulating gum cover forms the jacket hole of running through fully, the bottom of antenna terminal is intercalated in the jacket hole, the core of fixed screw head offers the suit hole, and insulating gum cover is intercalated in the suit hole of fixed screw head.
Wherein, the lower surface of described plastic core is equiped with the label that is printed with band number.
The beneficial effects of the utility model are: a kind of interphone antenna described in the utility model, include encapsulate in plastic core, the spring antenna core of one and the antenna terminal that is positioned at the bottom of plastic core, plastic core is fitted with the antenna protection cover, the core of antenna protection cover forms the containing cavity that Open Side Down, and plastic core is flush-mounted in the containing cavity of antenna protection cover; The lower surface of plastic core forms card holding trough, be embedded with successively insulating gum cover and fixed screw head in the card holding trough, the core of insulating gum cover forms the jacket hole of running through fully, the bottom of antenna terminal is intercalated in the jacket hole, the core of fixed screw head offers the suit hole, and insulating gum cover is intercalated in the suit hole of fixed screw head.In the utility model use procedure, the utility model is fixed in the intercom body by the fixed screw head, and insulating gum cover is spaced apart with fixed screw head and antenna terminal, and then avoids the fixed screw head to contact with antenna terminal; Spring antenna core of the present utility model and antenna terminal form integral structure by injection moulding encapsulate mode and plastic core, and for traditional split-type structural, the utility model can be saved a glue material effectively; In addition, plastic core has advantages of strengthens whole interphone antenna intensity, and then so that whole interphone antenna be difficult for being lost.Comprehensive above-mentioned situation the utlity model has the good advantage of Stability Analysis of Structures, long service life and durability as can be known.
Description of drawings
