In addition, a halved tie terminal 22 is equipped on the opposition side in larger diameter flange portion 13.One halved tie terminal 22 is equipped on, with reel 10 be benchmark depart from 180 the degree the position that becomes a straight line on (in larger diameter flange portion 13, becoming the position of opposition side).In addition, a halved tie terminal 22 is on the position of its opposition side, with towards along slightly being set perpendicular to the attitude of the direction of larger diameter flange portion 13 and reel 10 outer peripheral faces.
Therefore, if while apply tensile stress and will wind the line and 4 be wound on a halved tie terminal 22 and the reel 10, coiling 4 is wound in the root portion (from the outstanding root portion of larger diameter flange portion 13) of a halved tie terminal 22.As shown in Figure 4, coiling 4 and coiling 4 irrespectively are wound in the root portion (from the outstanding root portion of larger diameter flange portion 13) of a halved tie terminal 22 for the coiling direction of reel 10.
In addition, as shown in Figure 5, even coiling 4 under the big situation of the diameter of reel 10, also is wound in the root portion (from the outstanding root portion of larger diameter flange portion 13) of a halved tie terminal 22.Fig. 5 is used for explaining that antenna assembly 1 reel 10 with respect to Fig. 1 is by the ideograph of the method for winding antenna assembly 1 of ever-larger diameters, coiling 4.
Consequently; In the antenna assembly 1 of this example one, coiling 4 and the diameter for the coiling direction of the coiling 4 of reel 10 or reel 10 irrespectively are wound in the root portion (from the outstanding root portion of larger diameter flange portion 13) of a halved tie terminal 22.In coiling 4, can not exist with for the diameter of the coiling direction of reel 10 or reel 10 irrespectively, drawing the position and finishing the situation that forms aerial wiring part on the position of drawing of side in the beginning side of coiling 4.
Fig. 6 is the front view of the terminal board 31 in the antenna assembly 1 of comparative example.The terminal board 31 of this comparative example is provided with, and is formed with the Shu Duanzi 33 of a pair of jut 32 on the user's terminal 21 of rectangular shape and the side of rectangular shape.And user's terminal 21 is connected, slightly is parallel configuration to form through link 23 with Shu Duanzi 33.In Fig. 6, be represented by dotted lines edge with respect to the larger diameter flange portion 13 of the terminal board 31 of comparative example.The terminal board 31 of comparative example is positioned along the neighboring of larger diameter flange portion 13 like a pair of jut 32, and is equipped in the larger diameter flange portion 13.
In the terminal board 31 of the comparative example of this Fig. 6,4 be wound in 33 last times of Shu Duanzi will winding the line, coiling 4 is hung on a pair of jut 32.Coiling 4 can be from the front of a pair of jut 32 beam-deflection terminals 33.Therefore, coiling 4 is wound in respect to a pair of jut root portion 32 insides, a halved tie terminal 33 (from the outstanding root portion of larger diameter flange portion 13).In coiling 4, be not easy with for the diameter of the coiling direction of reel 10 or reel 10 irrespectively, drawing the position and finishing drawing of side and form aerial wiring part on the position in the beginning side of coiling 4.
But the terminal board 31 of the comparative example of Fig. 6 has high requirement as the positional precision with respect to the edge of larger diameter flange portion 13.Thereby in order 4 to hang over the root portion that makes coiling 4 be wound in a halved tie terminal 33 on a pair of jut 32 (from the outstanding root portion of larger diameter flange portion 13) through winding the line, a pair of jut 32 must be equipped on the neighboring adjoining position with larger diameter flange portion 13 accurately.If by being set, coiling 4 can be wrapped in respect to the root portion of a halved tie terminal 33 part near front a pair of jut 32 away from the neighboring of larger diameter flange portion 13.Might form aerial wiring part in the coiling 4.Therefore, in the terminal board 31 of the comparative example of this Fig. 6, pretty troublesome for the neighboring of larger diameter flange portion 13 to bit manipulation.Be difficult to be equipped in the larger diameter flange portion 13 with the terminal board 31 of sufficient precision with comparative example through inlaying shaping.
With respect to this; As this example; Under just Shu Duanzi 22 being formed rectangular shape (rectilinear form) and will winding the line 4 situation about being wound on the Shu Duanzi 22 of (rectilinear form) of this rectangular shape; Even Shu Duanzi 22 with respect to the not high situation of the positional precision at the edge of larger diameter flange portion 13 under, the root portion that coiling 4 also is wound in a halved tie terminal 22 securely (from the outstanding root portion of larger diameter flange portion 13).Coiling 4 can beam-deflection terminal 22 front and twined.In the Shu Duanzi 22 of the rectangular shape of this example, the positional precision as with respect to the neighboring of larger diameter flange portion 13 does not require the high position precision.
As stated, if adopt this example, the pair of end daughter board 5 that is provided with user's terminal 21 and Shu Duanzi 22 is equipped in the larger diameter flange portion 13.This halved tie terminal 22; On the position of the opposition side in the middle of ground is held on reel 10 as being arranged on the straight line with reel 10, with towards along slightly perpendicular to the direction of larger diameter flange portion 13 and reel 10 outer peripheral faces, promptly towards being set along being the direction and the quilt that extend radially with the center of parts 2 from coiling.
Therefore, on one side coiling 4 when applying tension force and be wound in a halved tie terminal 22, be wound in the root portion (root portion of giving prominence to from larger diameter flange portion 13) of a halved tie terminal 22 after being stretched through tension force.Coiling 4 and coiling 4 irrespectively are wound in the root portion (from the outstanding root portion of larger diameter flange portion 13) of a halved tie terminal 22 for the coiling direction of reel 10 etc.Therefore, can not form outstanding laterally aerial wiring part in the coiling 4 from the neighboring of larger diameter flange portion 13.Drawing the position and finishing drawing on the position of side of the beginning side of coiling 4 can not form aerial wiring part.
In addition; In the antenna assembly 1 under prior art; As illustrated in the problem to be solved by this invention part, in the middle of a halved tie terminal 22 is held on reel 10 and be equipped under the locational situation of relative opposition side, the possibility that forms aerial wiring part is high.
Consequently; In the antenna assembly 1 of this example; Be applied in vibration or heat etc. even be used in the keyless access system etc. of vehicle, the position of drawing of drawing the position and finishing side of the beginning side of coiling 4 can be not times without number bump with the edge of flange part yet.Coiling 4 is difficult for broken string.In addition, even the position of drawing of drawing the position and finishing side of 4 the beginning side of will not winding the line forms the twisted wire structure, or do not utilize bonding agent to fix, coiling 4 also is difficult for broken string.
In addition, the antenna assembly 1 of this example, 4 the broken string of drawing the position of need not being used to prevent to wind the line, twisted wire operation or bonding process etc., therefore can not produce the increase of the process number that causes because of these operations or the problem that cost improves.The antenna assembly 1 of this example can be through with the same process number of other coil parts that adopt coiling 4 and became original formation.
In addition, in this example, user's terminal 21 of Shu Duanzi 22 and the device 1 that is used to fix up an aerial wire is one to one by integration.In addition, a halved tie terminal 22 is equipped in the larger diameter flange portion 13 with a pair of user's terminal 21 jointly.
Under the situation on the same flange part that will be equipped on larger diameter flange portion 13 grades with a halved tie terminal 22 of user's terminal 21 integrations, antenna assembly is installed on printed circuit board (PCB) etc. with a side that is equipped with this halved tie terminal 22.When mounted, a halved tie terminal 22 and be wound in the both ends of the coiling 4 on the Shu Duanzi, easily and the miscellaneous part of printed circuit board (PCB) etc. disturb.Therefore, in general, must make a halved tie terminal 22 grades crooked, more to leave with respect to a pair of user's terminal 21 from printed circuit board (PCB) etc. at next halved tie terminal 22 of installment state.In addition, waiting situation about bumping with larger diameter flange portion 13 grades in order to reduce coiling 4 because of vibration, is good with a crooked halved tie terminal 22 significantly.
With respect to this, in this example, coiling 4 is wound in the root of Shu Duanzi 22, does not form aerial wiring part.Need be for the possibility that reduces broken string crooked significantly halved tie terminal 22 etc.One halved tie terminal, 22 grades are as long as bend to the degree that interference takes place the miscellaneous part of difficult and printed circuit board (PCB) etc. slightly.Therefore, can accurately a halved tie terminal 22 and a pair of user's terminal 21 be positioned, and can easily be equipped on larger diameter flange portion 13 etc. through when the resin casting mold is shaped, inlaying shaping.
