Abstract
The utility model discloses a built-in antenna apparatus, used in the mobile communication equipments provided with an outer casing, an inner casing, and a circuit board. The built-in antenna apparatus comprises an antenna body, whose one side is fixed to the inner side of the outer casing, an earthing part, extending out in integration from the antenna body and being basically vertical to the antenna body, a signal induction part extending out in integration from the antenna body and being basically vertical to the antenna body, and a guiding part respectively arranged in the inner casing corresponding to the earthing part and the signal induction part. The earthing part and the signal induction part are connected in electricity with the circuit board by passing through the guiding part respectively. When suffering the pressure, because the clamping effect of the inner wall of the guiding part to the earthing part and the signal induction part, the conductivity bad contact lead by the deflection of the contact point between the earthing part and the signal induction part and the circuit board is avoided.
Description
Technical field
The utility model relates to a kind of Built-in antenna apparatus, specifically, relates to the Built-in antenna apparatus between a kind of shell body inner housing that is arranged on mobile communication equipment.
Background technology
Because the wireless communication technique of electromagnetic wave transmission signal has the convenience of remote use, and the various product categories of wireless communication technique of utilizing are maked rapid progress, especially the use of mobile phone is more popular.Because what mobile phone used is electromagnetic wave transmission signal, therefore the antenna assembly in order to the induced electricity magnetic wave is a necessary device in the mobile phone.The antenna assembly of exposed conveying appliance has the shortcoming that is subjected to the foreign object collision easily and produces bending, fracture, and the Built-in antenna apparatus that therefore is arranged at casing inside, the mobile phone back side more and more receives an acclaim.
Consult Fig. 1, as what disclosed among No. 6,414,641, the United States Patent (USP) US, be applied to communication apparatus, as the Built-in antenna apparatus in the mobile phone, comprise a body 11 ', this body 11 ' is a metal plate, is fixed on the shell body (not shown); One grounding parts 12 ', it extends and vertical substantially with body 11 ' from body 11 ' one side one, and its front end passes the inner housing (not shown) of communication apparatus and circuit board 14 ' and electrically connects in the mode of crimping; One induction of signal portion 13 ', but induced electricity magnetic wave signal, its local one that goes up close grounding parts 12 ' from body 11 ' is extended and is vertical substantially with body 11 ', its front end passes the inner housing (not shown) of communication apparatus and circuit board 14 ' and electrically connects in the mode of crimping, is electric connection by body 11 ' and grounding parts 12 ' simultaneously.The antenna assembly of this kind form does not expose stretching out outside the casing, so be commonly referred to as Built-in antenna apparatus owing to be to be hidden in the casing of mobile phone.
As everyone knows, grounding parts 12 ' and induction of signal portion 13 ' are the necessary conditions that realizes communication with the circuit board electric connection.Nowadays the profile of mobile phone is all pursued small and exquisitely and attractive in appearance, and this size that just requires Built-in antenna apparatus is also wanted corresponding miniaturization.Grounding parts 12 ' of the prior art and induction of signal portion 13 ' have also carried out miniaturization in order to have adapted to this trend.This just cause that the own intensity of grounding parts 12 ' and induction of signal portion 13 ' descends to some extent and and circuit board between pressure excessive, the front end face that itself and circuit board electrically connect also reduces, angulation changes between grounding parts 12 ' and induction of signal portion 13 ' and the body 11 ' thereby cause easily, and the front end face of grounding parts 12 ' and induction of signal portion 13 ' and the contact point of circuit board are offset easily to cause the serious consequence of poor electrical contact.This just has higher requirement to the steadiness and the reliability of built-in aerial in the mobile phone and circuit board electric connection.
Summary of the invention
The purpose of this utility model is, a kind of Built-in antenna apparatus is provided, change with angulation between the grounding parts that overcomes Built-in antenna apparatus and induction of signal portion and the body, the front end face of grounding parts and induction of signal portion and the contact point of circuit board are offset easily to cause the technical problem of poor electrical contact.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of Built-in antenna apparatus is used to include in the mobile communication equipment of shell body, inner housing and circuit board; Described Built-in antenna apparatus comprises: antenna body, and it comprises relative two sides, it simultaneously is fixed on the medial surface of shell body; Grounding parts, it extends and vertical substantially with this antenna body from described antenna body one; Induction of signal portion, it extends and vertical substantially with this antenna body from described antenna body one; Guidance part is arranged on the position of corresponding described grounding parts and induction of signal portion on the described inner housing, and grounding parts and induction of signal portion pass guidance part respectively and circuit board electrically connects.
The corresponding another side of described antenna body can be fixed on the inner housing by a location substrate.
The corresponding another side of described antenna body also can directly be fixed on the inner housing.
Adopt above-mentioned Built-in antenna apparatus, grounding parts and induction of signal portion pass respectively after the central through-hole of each self-corresponding guidance part with mobile phone in circuit board become to electrically connect.When grounding parts and induction of signal portion are under pressure, because the inwall of guidance part is to the clamping action of grounding parts and induction of signal portion, avoid grounding parts and induction of signal portion to produce the bending distortion, thereby also avoided the contact point skew between grounding parts and induction of signal portion and the circuit board and the poor electrical contact that causes.Consider that antenna body can't bear too big power, between antenna assembly and inner housing, increased a location substrate, further firm antenna assembly, thereby make reach between antenna assembly and the circuit board firm, electrically connect reliably.
