Description

Receiver

Technical field

The front end that the present invention relates to be used to be accommodated in the cable of drawing is provided with the receiver of the electric components such as exterior antenna of connector plug.

Background technology

Generally, use the wireless communication card of the interior dress radio communication function as at the PHS of PC card inside (personal handyphone system) with the home computer with when carrying information terminal etc. and being connected on the telecommunication circuit transceive data.

The PC card modem 100 of wireless communication card for example shown in Figure 9 is made up of the antenna 103 that the housing section 101 of interior dress radio communication function, the PC card division 102 of giving prominence to from these housing section 101 lower ends and folding freely are arranged on housing section 101 tops; PC card division 102 is inserted in the PC card slit 104 that is arranged on the personal computer 105, uses to connect.

But, with such PC card modem 100 receiving and transmitting signal data the time, owing to the difference of behaviour in service, electric wave can not carry out good wireless communication out of order sometimes.Therefore also can be situated between helps connecting box that not shown exterior antenna is connected use with housing 101.

Therefore the user must hold PC card modem 100 and holds exterior antenna and stube cable etc. again and walk.At this moment, in order to prevent to adhere to dust etc., generally when holding away, these are accommodated in receiver or the collecting bag etc.

But, use simple structure, low-cost sleeve antenna mostly as the exterior antenna that carries usefulness as described above.This sleeve antenna has the roughly shape of cylinder, at the front end of the connecting box of drawing from an end, is provided with the connector plug 107 that is used to connect PC card modem 100 as shown in Figure 10.

And the roughly rectangular-shaped connector plug 107 of the front end that is arranged on the cable of drawing from electric components such as exterior antennas remain on the receiver 105 structure as shown in Figure 10 and Figure 11, retention tab 101 is set in that relative front end is outstanding respectively, a pair of flexible locking plate 103,103 that be arranged in parallel is arranged in the receiver.

Therefore, by roughly rectangular-shaped connector plug 107 being pressed between a pair of flexible locking plate 103,103, make connector plug 107 can not rock ground clamping connector plug 107 when receiver comes off because of carelessness.

As the occasion of above-mentioned a pair of flexible locking plate 103,103, when connector plug 107 dismounting, leading section in the outside along with strains (direction of arrow among Figure 11) take place retention tab 101.

Therefore, when described flexible locking plate 103 produces excessive deformation during in connector plug 107 dismounting repeatedly, produce tiredly, elastic recovery power is descended.The decline of the elastic recovery power of flexible locking plate 103 like this causes the power of seizing on both sides by the arms of connector plug 107 is descended, and can not reliably connector plug 107 be remained in the receiver 105.

Again, with described flexible locking plate 103 when the inner surface of receiver 105 forms one because the lower portion of described retention tab 101 becomes depression, exist finishing die to be complicated and problem that manufacturing cost rises.

Therefore purpose of the present invention is relevant with the above-mentioned problem of solution, provides a kind of receiver, and this receiver can suppress the raising of manufacturing cost when the connector plug that makes the cable front end is stablized and kept reliably.

Summary of the invention

The present invention is used to be accommodated in the receiver that the front end of the cable of drawing is provided with the electric component of connector plug.On the inwall of described receiver, standing and a pair of plug is set is keeping using wall with certain interval.The latch-release knob that is pressed when on of two sides of described connector plug, being arranged on latch-release at least and operates, described a pair of plug keeps with the described latch-release knob of wall clamping, be the pressured state that is pressed, and by described unlock to try hard to keep with the knob elastic recovery hold described connector plug.

According to described structure, when the connector plug on the front end that will be arranged on the cable of drawing from electric component is accommodated in the receiver with this electric component, a pair of plug maintenance is unlocked with clamping under the state of pushing that suppresses with wall install with the mode of knob.

Thereby, because being clamped in a pair of plug by self the elastic recovery power with knob of unlocking, described connector plug keeps with between the wall, needn't strain and plug is kept with wall self, do not need the retention tab of sagging shape yet.

In addition, described unlocking has sufficient elasticity stroke and durability in advance with knob, can still keep stable confining force through after working long hours.

And, preferably by make outstanding be arranged on described a pair of plug keep with the anti-offset projection on wall opposite by be entrenched in be formed on described unlock with the lip-deep on-slip of knob with the plug that limits described connector plug on the jog forwards, backwards direction move.

At this moment because when a pair of plug of connector plug one insertion keeps using between the wall, being arranged on plug keeps anti-offset projection with the wall opposite just to be entrenched in being arranged on connector plug to unlock in the usefulness on-slip jog of knob, so can prevent the skew of the fore-and-aft direction of this connector plug, and can keep reliably.

In addition, because described on-slip jog is to be used for when described connector plug limit is prevented the parts that finger tip slides when matching connector catches the limit to extract, so be that section is the jog of waveform along plug fore-and-aft direction (connector plug insert off-square to) usually.Therefore being entrenched in described anti-imitative skew projection on the jog of this section waveform can make along the costal process that prolongs with receiver internal face vertical direction and rise.That is to say, also can not cave in when on plug keeps with the opposite of wall, forming one.

In addition, described anti-offset projection is projected upwards in the front and back along described connector plug be provided with a plurality of.

Therefore, when being accommodated in described connector plug in the receiver, because the influence of cable, even one in front and one in back in the connector plug holding position, as long as at least one anti-offset projection is entrenched in described on-slip with in the jog, a pair of plug keeps just keeping this connector plug reliably in the skew limit of energy frontier defense ending fore-and-aft direction with wall.

In addition, preferably will be used to limit the limiting wall of the restriction plug fore-and-aft direction of described connector plug position, in described on-slip can keep with the chimeric scope of the anti-offset projection of wall with described plug with jog, outstanding being arranged on the inwall of described receiver.

Therefore, when being accommodated in described connector plug in the receiver, even the holding position of this connector plug one in front and one in back, as long as among described plug fore-and-aft direction limiting wall, at least one anti-offset projection just can be entrenched in described on-slip with in the jog.Thereby, keeping with between wall even because of carelessness described connector plug is inserted a pair of plug, a pair of plug keeps also preventing with wall the skew of fore-and-aft direction, keeps this connector plug reliably.

And described electric component is the exterior antenna that radio communication is used, and is contained with the wireless communication card of interior dress radio communication function.

This occasion under the state of the connector plug that the cable front end of drawing from exterior antenna keep to be set reliably, can be held away the Portability excellence to these and wireless communication card together.

To be elaborated to the receiver that relates to one embodiment of the present of invention with reference to the accompanying drawings below.

The wireless communication card receiver 1 of present embodiment is plastic receiver as shown in Figure 1 to Figure 3, the exterior antenna 5 that its integral body takes in PC card modem 3 as wireless communication card, use as the radio communication of electric component and be arranged on the connector plug 31 of the front end of the stube cable 7 of drawing from this exterior antenna 5 roots.

And described wireless communication card comprises with receiver 1: exterior antenna 5, stube cable 7 and connector plug 31 are accommodated in the flat box-like box main body 9 of assigned position and freely lean on pivoted and take in the flat lid 11 of described PC card modem 3 on this box main body 9.

Simultaneously with reference to Fig. 4, described box main body 9 comprises: dull and stereotyped rectangular-shaped top board 13 is vertically set on sidewall 15L, the 15R on the length direction both side edges (two edge about among Fig. 3) along this top board 13 and is vertically set on the antetheca 17 of length direction front-end edge (right-hand member edge among Fig. 2).

Again, the rear wall 19 that is vertically set on described top board 13 length direction rearward end (left part among Fig. 2) is because the preceding end in contact of the upper wall that is arranged on the bag portion 71 on the lid 11 that will narrate with the back, becomes to be approximately half height of box main body 9.

The rear end of described two

side

15L, 15R as shown in Figure 4, and is rearward outstanding from rear wall 19 respectively.On its medial surface separately, freely rotate the outstanding columned rotating shaft projection 25 that is provided with in order to make described lid 11 pass through pivot.And depression is provided with described rotating shaft projection 25 chimeric rotation axis recess (not shown)s on two sides of corresponding lid 11.

And in described box main body 9, take in: such as described above exterior antenna 5, stube cable 7 and connector plug 31 that this exterior antenna 5 is connected with PC card modem 3, described connector plug 31 are installed in the front end of this stube cable 7 and are used for connecting the connecting portion 70 of the housing section 69 of PC card modem 3.

Described exterior antenna 5 is the so-called sleeve-dipole antenna of pole shape roughly as shown in Figure 1, comprises the large-diameter portion 35 of the root side that is connected with stube cable 7 and by coniform 37 minor diameter 33 that is extended down to front.

Described stube cable 7 is situated between and helps connecting portion 39 to be installed on the root of described exterior antenna 5 towards the direction with the axis orthogonal of exterior antenna 5.

And described exterior antenna 5 is contained along the sidewall 15L of described box main body 9 as shown in Figure 4.

Again, root (bottom among Fig. 4) at described exterior antenna, such shown in Fig. 4 amplification, for example hemispheric chimeric recess 41 is set as the box fitting portion, be used for chimeric pivot on this chimeric recess 41, prevention is moved to the right angle orientation of axis, simultaneously can be on the inner surface of conical mosaic process 43 that center line the keeps described exterior antenna 5 rotatably prominent rear wall 19 that is arranged on described box main body 9 as the antenna fitting portion.

On the other hand, under described mosaic process 43 is entrenched in state in the chimeric recess 41 of exterior antenna 5, the outstanding resilient flexibility sheet 45 that is provided with on the inner surface of the described top board 13 of the leading section that is arranged in this exterior antenna 5 (upper end of Fig. 4).This its elastic recovery power of resilient flexibility sheet 45 usefulness makes the leading section of exterior antenna 5 suppress the root side, keeps the chimerism of described chimeric recess 41 relative mosaic processes 43.

And under described mosaic process 43 is entrenched in state in the chimeric recess 41 of exterior antenna 5, on the inner surface of the described top board 13 that is positioned at 5 coniform 37 of this exterior antennas, forms the antenna that wears through hole 49 and keep with rib 47.The internal diameter of this through hole 49 is bigger than the minor diameter 33 of described exterior antenna 5, and is littler than large-diameter portion 35.

And when described exterior antenna 5 being taken in when remaining in the box main body 9, at first the downside from Fig. 4 makes the front end of the minor diameter 33 of exterior antenna 5 keep through hole with rib 47 by antenna, makes the front end of this minor diameter 33 be pressed in deflection on the resilient flexibility sheet 45.

Secondly, under this state, make the chimeric recess 41 of the root that is arranged on exterior antenna 5 chimeric with the mosaic process of box main body 9.Like this since the elastic recovery power of described resilient flexibility sheet 45 that the chimeric recess 41 of exterior antenna 5 is pressed in the mosaic process 43 of box main body 9 is chimeric, exterior antenna 5 can kept under the state around rotational reliably.

On the inner surface of the top board 13 of described box main body 9, as shown in Figures 1 to 4, the cable that is used for described stube cable 7 is remained on assigned position keeps guiding 51 to form one.This cable keeps guide groove 51 to constitute by oval-shaped inwall rib 53 with for stube cable 7 being clipped in the outer wall rib 55 that keeps certain intervals and inwall 53 to be arranged in parallel between this inwall rib.

And as shown in Figure 4, the connector plug maintaining part 57 that is used for fixing described connector plug 31 is arranged on the inside of described inwall rib 53.

This connector plug maintaining part 57 is by keeping the plug rear limiting

wall

65,65 of plug the place ahead limiting wall 63 of the scope that

walls

61,61, restriction connector plug 31 forwards move and the scope that restriction connector plug 31 rearward moves to form one in the inside of the top board 13 of box main body 9 with the corresponding locational pair of right and left plugs of

knob

59,59 constituting with being arranged on to unlock on described connector plug 31 two sides.

Described unlocking as shown in Figure 5 and Figure 6 with

knob

59,59, be the parts of mechanism of unlocking, this locking mechanism is when being connected connector plug 31 on the PC card modem 3, for preventing to come off, make its locking, be arranged on two sides of connector plug.

And these unlock with knob the 59, the 59th, by keeping respectively the parts of extruding to the inside here as far as possible, often suppress laterally with the elastic recovering force of spring etc. when latch-release, and making goes smoothly can return to latched position once leaving.

As shown in Figure 6, the inner surface of described top board 13 standing a pair of plug that is provided with keep setting usually with the distance b of the inner surface of

wall

61,61 than about unlock smaller with the lateral surface of

knob

59,59 apart from B so that extruding, suppress under the state can clamping these unlock and use

knob

59,59.

Thereby, when the connector plug 31 that makes the front end that is arranged on the stube cable 7 of drawing from exterior antenna 5 is accommodated in the box main body 9 with this exterior antenna 5, unlocking of described connector plug 31 is installed uses

knob

59,59, make a pair of plug keep pushing clamping under the state of suppressing with

wall

61,61.

Therefore, because the elastic recovering force that unlocks with

knob

59,59 of described connector plug 31 usefulness self is clamped between a pair of plug

maintenance usefulness wall

61,61, so plug keeps itself not needing strain with wall 61, also need not form the retention tab 101 of the such depression of as shown in Figure 10 and Figure 11 flexible locking plate 103.

Again,, have sufficient elasticity stroke and durability in advance, so after through long-time the use, still can keep stable confining force because described unlocking often suppressed laterally with elastic recovering forces such as

knob

59,59 usefulness springs as described above.

And as shown in Figure 7, be provided as the serrations 60 of the jog of on-slip with the outside of knob 59 described unlocking.Because described serrations 60 is to be used for the parts that prevent finger tip slip of described connector plug 31 when the connecting portion 70 of PC card modem 3 is caught and extracted, so be jog along plug fore-and-aft direction (the slotting off-square of connector plug to) section waveform.

On the other hand, keep with on the opposite (the inside) of

wall

61,61 at described a pair of plug, the anti-offset projection 62 that is entrenched in a plurality of (for example being three herein) of the size on the jog of described serrations 60 plays the formation one as the costal process that prolongs on the straight line of above-below direction (the vertical direction of receiver internal face relatively).

Promptly,, forming metal mould is complicated, thereby can not improve manufacturing cost so can not form depression because described anti-offset projection 62 is to rise at the costal process that the direction vertical with receiver 9 internal faces (metal pattern moving direction) prolongs.

Thereby, in case connector plug 31 is inserted described a pair of plug to be kept with between the

wall

61,61, because in plug keeps being entrenched in the anti-offset projection 62 that wall 61 opposites are provided with serrations 60 on the usefulness knob 59 that unlocks that is arranged on connector plug 31 concavo-convex, so can prevent the skew of these connector plug 31 fore-and-aft directions, can keep reliably.

And, since described anti-offset projection 62 along the plug fore-and-aft direction of described connector plug 31 outstanding be provided with a plurality of, so when being accommodated in described connector plug 31 in the box main body 9, because the influence of the receiving state of stube cable 7, described relatively connector plug maintaining part 57, even the holding position of this connector plug 31 one in front and one in back, as long as at least one anti-offset projection 62 is entrenched in the recess of described serrations 60, a pair of plug keeps just preventing the skew of fore-and-aft direction with

wall

61,61, and keeps this connector plug 31 reliably.

By the connector plug 31 of plug the place ahead limiting wall 63 and plug

rear limiting wall

65,65 restrictions direction ultimate range H movably forwards, backwards, such as shown in Figure 7 and Figure 8, become the distance of recess that plug keeps being entrenched in at least one of the anti-offset projection 62 of

wall

61,61 serrations 60 of the described usefulness knob 59 that unlocks.

Promptly constitute H≤h1+h2 by the distance h 1 of the anti-offset projection 62 of two ends with from distance h 2 at the recess of two ends of serrations 60.

Thereby, when stube cable 7 when cable guide 51 is taken in, the position of the fore-and-aft direction of the connector plug 31 of described relatively connector plug maintaining part 57 even only be offset H, keeps also keeping connector plug 31 reliably with

wall

61,61 with plug.

In addition, be preferably in described plug and keep, the gap that a described connector plug 31 makes the operator when described connector plug maintaining part 57 is taken out finger can enter is set with between

wall

61,61 and the described

rear limiting wall

65,65.

Described PC card modem 3 is made up of the antenna 68 that the housing section 69 of interior dress radio communication function, the flat PC card division 67 of giving prominence to from the lower end of this housing section 69 and folding freely are arranged on housing section 69 tops, and described connector plug 31 is connected in the connector portion 70 that is located at the back side.

Then, insert the bag portion 71 (with reference to Fig. 1) that is arranged on the described lid 11 by leading section with described PC card division 67, when lid 11 is closed, make the cable of box main body 9 keep overlapping on guide groove 51 and the connector plug maintaining part 57, PC card modem 3 is accommodated in wireless communication card with in the receiver 1.

Thin plate shaped PC card division 67 overlappings that are PC card modem 3 are accommodated in above-mentioned the cable maintenance guiding 51 and connector plug maintaining part 57.Owing to be accommodated in than PC card division 67 thick and outstanding housing section 69 and do not disturb cable to keep in the space (space on right side among Fig. 2) of guiding 51, therefore, wireless communication card can be made minimum with the thickness of receiver 1.

Thereby, also external form can be done for a short time with the exterior antenna 5 of PC card modem 3 although the wireless communication card of present embodiment is taken in receiver 1 integral body, seek miniaturization.

Again, under the state of the connector plug 31 of the front end that keeps being arranged on the connection antenna 7 of being drawn by exterior antenna 5 reliably, can hold them together and the PC card modem is walked, Portability is good.

And when using described PC card modem 3 and described exterior antenna 5, use rotation axis projection 25 as center of rotation, make lid 11 relative box main body 9 rotating opening, the PC card modem 3 that takes out is inserted in the PC card slot of personal computers 105 and connect.

Then, under the previous status that described exterior antenna 5 is accommodated in the box main body 9, draw stube cable 7, as shown in Figure 5, connector plug 31 is connected on the connecting portion 70 of PC card modem 3.

At this moment, described exterior antenna 5 is because can be around remaining on the box main body 9 under the state of rotational, so can guide stube cable 7 into desirable direction.

And make lid 11 after box main body 9 rotates more than 270 degree, because the rear wall 19 of box main body 9 is contacted with the lateral surface of lid 11, restriction is rotated.As shown in Figure 5, make box main body 9 and lid 11 keep the roughly open angle of quadrature.

Therefore since described lid 11 to become base station such, described wireless communication card is placed on the horizontal stand with receiver 1, be in the exterior antenna 5 relative table tops that are accommodated in the interior state of box main body 9 same as before and keep the roughly angle of orthogonal.

In addition, consider that preferably the angle of table top surpasses 70 degree relatively from the gain aspect of described exterior antenna 5.But the angle at relative table top is similar to 90 degree and surpasses 90 occasions of spending, owing to worry box main body 9 falls down, so make than the little angle of 90 degree.

And the connector plug maintaining part that relates to receiver of the present invention be not limited in described embodiment the structure of connector plug maintaining part 57, can certainly adopt various modes.

For example, though in the above-described embodiments, keep having established three anti-offset projections 62, the invention is not restricted to this with the opposite of wall 61 is prominent at plug.

In the above-described embodiments, the wireless communication card of taking in the exterior antenna of using as the radio communication of electric component 3 is illustrated as receiver of the present invention with receiver 1 again.But the present invention is not limited only to this.For example, so long as take in the receiver of electric component of the connector plug of the front end that is arranged on the cable of drawing from various electric components such as head-telephone, microphones, can both be suitable for.

Though with reference to certain embodiments the present invention is had been described in detail, the practitioner understands, only otherwise break away from the spirit and scope of the present invention, can carry out various changes and modifications.

The application proposes on the basis of the Japan's special permission application (special permission application 2001-100497) in March 30 calendar year 2001 application, its content as this with being that reference is taken.

According to aforesaid receiver of the present invention, when the connector plug of the front end that will be arranged on the cable of drawing from electric component and this electric component were accommodated in the receiver together, a pair of plug kept installing like that with knob at the latch-release of pushing the described connector plug of clamping under the state of suppressing with wall.

Keep with between the wall because described connector plug is clamped in a pair of plug with self latch-release with the elastic recovery of knob, plug keeps needn't strain with wall self, and the retention tab that formation is caved in is also unnecessary.Thereby do not have receiver molding metal mold complexity, the problem that manufacturing cost rises.

Again, described latch-release knob is in advance with the elastic recovering force of spring etc., the parts that often suppress laterally, owing to have sufficient elasticity stroke and durability, can be through keeping stable confining force for a long time.
