The coaxial connector of belt switch

Technical field

The present invention relates to a kind of coaxial connector (socket of belt switch) of belt switch, the coaxial connector of this belt switch is used for for example communication equipment such as mobile phone of electronic equipment, by with cooperating of matching connector (being installed on the connector of the end of coaxial cable) contact being switched.

Background technology

The coaxial connector of belt switch can be installed on the surface of substrate in the following manner, promptly in the occasion that for example is used for mobile phone, to check the electrical characteristics of high-frequency circuit when dispatching from the factory, at this moment, by cooperating the matching connector that is connected with this determinator, be connected to determinator thereby high-frequency circuit switched from antenna, by pulling down matching connector, thereby once more high-frequency circuit be connected in antenna; In order to make mobile phone etc. use object-based device miniaturization, slimming, wish to realize as much as possible miniaturization, low level.

For miniaturization, the low level of the coaxial connector of realizing belt switch, but how in the design of the movable contact spring member of the leaf-spring-like that constitutes by sheet metal, reduce concentrated stress, improve the life-span property of plug repeatedly extremely important.Past has such technology,, but by the movable contact spring member is formed the S tee section, can increase the spring total length that is, makes it small-sized and can reduce concentrated stress, improves life-span property No. the 2889562nd, Japanese patent gazette (for example with reference to).Yet, owing to form spring in latch plug direction, so there is certain limit in low level.In addition, the contact of latch contact site load changes with the insertion stroke of latch, so the less stable of electrical connection is unfavorable for the mensuration of high frequency characteristics etc.Because have these problems, so, develop the movable contact member of sening as an envoy to and move and coaxial connector formation, belt switch (for example opening 2003-59597 number) of double-throw contact with reference to the Japanese patent gazette spy towards the cardinal principle direction vertical with the plug direction of latch.

Yet, but the coaxial connector of the belt switch in past is except fixed touch plate member and such 4 parts of movable contact spring member that insulating element, external conductor shell, switch are used, also have auxiliary substrate, relaying other parts such as pin, this auxiliary substrate has the soldering connecting portion that is used to be surface mounted to printed circuit board (PCB), but this relaying is electrically connected fixed touch plate member and movable contact spring member with the soldering connecting portion that pin is used for relative auxiliary substrate, for this reason, number of components is many, there is the high problem of component costs and assembly cost in complex structure.In addition, but but the latch contact site of movable contact spring member inserts the downside in zone by latch from the free side end of movable contact spring member, erect in its sidepiece form L shaped, along with the cooperating of matching connector, latch is contacted with the rising portions of latch contact site, the latch contact site is whole to be moved towards the direction vertical with latch plug direction cardinal principle, but thereby the moving contact portion antagonistic spring power that makes the movable contact spring member from the fixed contact part from, so, need further guarantee the thickness of slab amount of transverse part of latch contact site and the glade plane space of its transverse part at the downside that latch inserts the zone, become the disadvantageous structure of low level.

Summary of the invention

The object of the present invention is to provide a kind of coaxial connector of belt switch, but the coaxial connector of this belt switch has improved the life-span property and the contact reliability of movable contact spring portion, more small-sized than the past, highly low, and constitute by simple parts and to make cost also cheap.

In order to achieve the above object, the coaxial connector of belt switch of the present invention is characterised in that: have dead joint member that insulating element, external conductor shell, the switch of band tip circle tubular use, and movable connecting elements; This insulating element has pedestal portion integratedly in the bottom side, form the latch patchhole at the end face central part, and this latch patchhole is used for freely plugging along the cylinder axle center at the cylinder interior central part latch of matching connector; This external conductor shell has the columnar shell body in the cylinder outside that is matched with insulating element and extends the soldering connecting portion of setting along the bottom surface of insulating element from the shell body integratedly; This dead joint member has in the cylinder interior of insulating element accommodates the fixed contact portion of being fixed in the position of leaving from latch insertion zone and extends the soldering connecting portion of setting along the bottom surface of insulating element from fixed contact portion one; But but this movable connecting elements has the movable contact spring portion of the leaf-spring-like that is made of sheet metal and the soldering connecting portion that extends from movable contact spring portion one along the bottom surface of insulating element, but should movable contact spring portion the cylinder interior of insulating element be contained in cantilever position latch insert the zone around, plate width direction is parallel with latch plug direction, simultaneously, free side end inserts a regional part from the side by latch and extends to fixed contact portion, has by the moving contact portion and the latch contact site that be in same level of spring force Elastic Contact in fixed contact portion; Along with the cooperating of matching connector, the latch Elastic Contact is in the latch contact site, but movable contact spring portion resistance spring force towards moving with the vertical substantially direction of latch plug direction, thereby moving contact portion is left from fixed contact portion.

By adopting above-mentioned formation, the coaxial connector of belt switch only is made of dead joint member and the movable connecting elements that insulating element, external conductor shell, switch are used, promptly, constitute as the coaxial connector of this belt switch 4 parts by minimal parts quantity, can reduce the component costs and the assembly cost of the coaxial connector of belt switch, simultaneously, structure is also simplified.

But movable contact spring portion is towards moving relative to the vertical direction of latch plug direction cardinal principle, its amount of movement leaves determining apart from size of latch axle center by the outside dimension and the latch contact site (contact-making surface) of latch, the insertion stroke with latch does not change, so, but the contact load of stress that movable contact spring portion bears and latch contact site is for certain, and electric contact state is stable, and contact reliability improves, for example be used for the occasion of mobile phone etc., can obtain good high frequency characteristics at coaxial connector with belt switch.

But the movable contact spring portion of the leaf-spring-like that is made of sheet metal accommodates and plate width direction is parallel to latch plug direction in the cylinder interior of insulating element, so, but make the change of shape of movable contact spring portion in order to obtain suitable spring performance, change spring length, in addition,, stress changes appending and cancellation or bending radius of bend for being disperseed, but these only are the sectional areas that spatially increases and decreases movable contact spring portion, can increase and decrease less scope in the space tackles effectively, for this reason, but can improve the life-span property and the contact reliability of movable contact spring portion, realize the further miniaturization of the coaxial connector of belt switch.

But movable contact spring portion carries out bending machining towards length direction to rectangular sheet metal to form leaf-spring-like, can set latch contact site and moving contact portion at free side end, so, the shape of movable connecting elements obtains simplifying, widget processing can be easily carried out, the component costs and the assembly cost of the coaxial connector of belt switch can be further reduced.

The latch contact site can not extend to latch by latch with inserting regional downside and insert the zone, so, even, but also can accommodate movable contact spring portion, realize the further low level of the coaxial connector of belt switch by the space of the height identical with the insertion stroke of latch.

In the coaxial connector of belt switch of the present invention, the end, latch inserting side that is preferably in the latch contact site forms the latch introduction part of inserting the outside curve in zone towards latch.In addition, the relative position of clamping latch insertion zone that is preferably in the cylinder interior of insulating element forms latch and inserts the guiding wall, and this latch insertion guiding wall hangs down towards the latch direction of insertion continuously from the wall surface of the hole of latch patchhole.In the occasion that adopts this formation, the latch that latch forms D shape by a columnar part inserts the guiding wall and is guiding and insert, so, the axle center of latch can not produce big eccentric or insertion obliquely, and make latch sliding contact positively the contact surface side that is inserted into the latch contact site by the latch introduction part, can when obtaining high contact reliability, obtain certain contact change action of switch.

In addition, be preferably in the latch approaching face of latch introduction part and the bight of front end face formation and form chamfering.In the occasion that adopts this formation, can prevent that the latch approaching face of latch introduction part and the bight that front end face constitutes are hooked into the insulating element top part, but the action that the interference of eliminating movable contact spring portion and insulating element top part causes is bad, can when obtaining high contact reliability, obtain certain contact change action of switch.

In addition, but movable contact spring portion be preferably formed as into from the end of fixation side to the different form of the circumferential position of all sites of free side end.In the occasion that adopts this formation, but elimination repeats to eliminating radially the position of free side end in the fixation side end from movable contact spring portion, standoff distance is very approaching, be easy to the position that interfere on high frequency ground.In addition, but from the fixation side end of movable contact spring portion to the position except that free side end of free side end, can eliminate radially repeat, a part invades and is easy to when latch inserts zone, latch plug and position that latch is interfered.

According to the present invention, remarkable result that can be such promptly, but can improve the life-span property and the contact reliability of movable contact spring portion, realizes further miniaturization, the low level of the coaxial connector of belt switch, and can constitute the reduction of realization cost by simple parts.

The coaxial connector 1 of the belt switch of Huo Deing as described above, be engaged in the installed surface ground of the not shown printed circuit board (PCB) of mounting object, on printed circuit board (PCB), carry out mounted on surface by bottom surface, thereby soldering connecting portion 55 solderings of soldering connecting portion 42, movable connecting elements 50 of each soldering connecting portion 32a, 32b, dead joint member 40 of external conductor shell 30 that will be exposed to the bottom surface of insulating element 10 are connected on the pattern of correspondence of printed circuit board (PCB) insulating element 10.In this form of implementation, each soldering connecting portion 32a, 32b of external conductor shell 30 is electrically connected on the grounding pattern of printed circuit board (PCB), the soldering connecting portion 42 of dead joint member 40 is electrically connected on the antenna of mobile phone by the pattern of printed circuit board (PCB), the soldering connecting portion 55 of movable connecting elements 50 is electrically connected on the high-frequency circuit of mobile phone, with coaxial connector 1 mounted on surface of belt switch in the printed circuit board (PCB) of mobile phone and its diverter switch 60 is entered between the high-frequency circuit and antenna of mobile phone.The effect of coaxial connector 1 of the belt switch of this form of implementation is described below with reference to Fig. 7 and Figure 10.The matching connector of this occasion is the mensuration probe that is connected with the determinator of the electrical characteristics that detect high-frequency circuit, and such as everyone knows, the center of unshowned columnar external conductor has latch 100 in the drawings.

Such shown in Fig. 7 (a), coaxial connector 1 for belt switch, when before the cooperation of matching connector, not inserting latch 100, in the fixed contact 41a of dead joint member 40, the pattern by these connecting elementss 50,40 and printed circuit board (PCB) is electrically connected high-frequency circuit and antenna by the spring force Elastic Contact of spring portion 54 in the moving contact portion 56 of movable connecting elements 50.

When matching connector is matched with the coaxial connector 1 of belt switch, along with this cooperation, as Fig. 7 (b), as shown in Figure 9, latch 100 inserts guiding wall 17a, 18a guiding from latch patchhole 14 by approaching face 14a and latch, inserts towards the latch insertion zone 15 of the inside center portion of insulating element main body 12 along the axle center of insulating element main body 12.In this insertion process, the spherical front end face of latch 100 and the surface sliding contact of the cylinder shape of latch introduction part 59, the radial outside that inserts zone 15 (latches 100) towards latch pushes back latch contact site 57 ground, the spring force of latch contact site 57 antagonistic spring portions 54 is moved towards the direction vertical with latch plug direction, thereby inserts latch 100 in sliding contact under the state of the latch contact surface side of latch contact site 57.Like this, latch contact site 57 Elastic Contact are in the lateral surface of latch 100, simultaneously, be set in these latch contact site 57 same levels on moving contact portion 56 leave from the fixed contact 41a of dead joint member 40, high-frequency circuit switches from antenna by latch 100 and is connected to determinator.

But the spring portion 54 of movable contact spring portion 51 is by being formed at the outermost periphery slot part 19b of switch reception room 16, the outside of inserting zone 15 from the latch of anchor portion 52 sides is transferred to the outside of inserting zone 15 with the latch of anchor portion 52 opposition sides, so, have enough spring length; And, spring portion 54 has the 1st bend 54d and the 2nd bend 54e, the bend 54d, the 54e that stress are distributed to 2 positions design spring with bearing, so, can not produce big bending moment in the part, be difficult for to produce the deterioration of the spring performance that relative latch 100 plug repeatedly, can improve the life-span property that plugs repeatedly of relative latch 100.In addition, latch contact site 57 plugs on the same level of the parallel free side end 54b of direction with latch with the Width that moving contact portion 56 is set in spring portion 54, and, latch contact site 57 is set in the base end side of free side end 54b, moving contact portion 56 is set in the front of free side end 54b, so latch contact site 57 is not 1 to 1 with the amount of movement of moving contact portion 56, compare with the amount of movement of latch contact site 57, the amount of movement of moving contact portion 56 increases.For this reason, can obtain the reliable contact change action of diverter switch 60.The amount of movement of the needed moving contact of the contact change action portion 56 of diverter switch 60 can obtain by the amount of movement of the latch contact site 57 littler than its amount of movement conversely speaking.For this reason, can reduce the resilient movement amount of spring portion 54, but in the life-span property that improves movable contact spring portion 51, also effective to the miniaturization of the coaxial connector 1 of belt switch.

Pull down matching connector as coaxial connector 1 from belt switch, then the internal switch reception room 13 from the insulating element main body 12 of insulating element 10 takes out latch 100, latch contact site 57 is disconnected with contacting of latch 100, simultaneously, by the spring force of spring portion 54 make moving contact portion 56 once more Elastic Contact in the fixed contact 41a of fixed contact portion 41, latch contact site 57 elastic return are to entering the position that latch inserts the part in zone 15, and high-frequency circuit is electrically connected with antenna.

As described above, the coaxial connector 1 of belt switch has dead joint member 40 that insulating element 10, external conductor shell 30, the switch of band tip circle tubular use, and movable connecting elements 50; This insulating element 10 has the pedestal portion 11 that forms in the bottom side, form latch patchhole 14 at the end face central part, and this latch patchhole 14 is used for freely plugging along the cylinder axle center at the cylinder interior central part latch 100 of matching connector; This external conductor shell 30 has the columnar shell body 31 in the cylinder outside that is matched with insulating element 10 and extends soldering connecting portion 32a, the 32b that is provided with integratedly from shell body 31 along the bottom surface of insulating element 10; This dead joint member 40 has to accommodate to be fixed in from latch in the cylinder interior of insulating element 10 and inserts the fixed contact portion 41 of 15 positions of leaving, zone and extend the soldering connecting portion 42 that is provided with from fixed contact portion 41 one along the bottom surface of insulating element 10; But but this movable connecting elements 50 has the movable contact spring portion 51 of the leaf-spring-like that is made of sheet metal and the soldering connecting portion 55 that extends from movable contact spring portion 51 one along the bottom surface of insulating element 10, but should movable contact spring portion 51 the cylinder interior of insulating element 10 be contained in cantilever position latch insert zone 15 around, plate width direction is parallel with latch plug direction, simultaneously, free side end 54b inserts the fixed contact portion 41 that extends to partially in zone 15 by latch from the side, have by the moving contact portion 56 and the latch contact site 57 that be in same level of spring force Elastic Contact in fixed contact portion 41; Along with the cooperating of matching connector, latch 100 Elastic Contact are in latch contact site 57, but movable contact spring portion 51 antagonistic spring power towards moving with the vertical substantially direction of latch plug direction, thereby moving contact portion 56 is left from fixed contact portion 41.

The dead joint member 40 that the coaxial connector 1 of belt switch is only used by insulating element 10, external conductor shell 30, switch, and movable connecting elements 50 constitute, promptly, coaxial connector as this belt switch only is made of 4 parts of minimal parts quantity, so, can reduce the component costs and the assembly cost of the coaxial connector 1 of belt switch, simultaneously, structure also can be simplified.

But movable contact spring portion 51 moves towards the direction vertical with latch plug direction cardinal principle, its amount of movement is only pressed the outside dimension of latch 100 and latch contact site 57 (contact-making surface) determining apart from size apart from the axle center of latch 100, the insertion stroke with latch 100 does not change, so, but the contact load of stress that movable contact spring portion 51 bears and latch contact site 57 is certain, status of electrically connecting is stable, contact reliability improves, as this form of implementation, be used for the occasion of mobile phone etc. at coaxial connector 1, can obtain the mensuration environment of good high frequency characteristics belt switch.

But the movable contact spring portion 51 of the spring-like that constitutes by sheet metal the cylinder interior of insulating element 10 be contained in cantilever position latch insert zone 15 around and plate width direction be parallel to latch plug direction, so, but make the change of shape of movable contact spring portion 51 in order to obtain suitable spring performance, change spring length, in addition,, stress changes appending and cancellation or bending radius of bend for being disperseed, but these only are the sectional areas that spatially increases and decreases movable contact spring portion 51, can increase and decrease less scope in the space tackles effectively, for this reason, but can improve the life-span property and the contact reliability of movable contact spring portion 51, realize the further miniaturization of the coaxial connector 1 of belt switch.

But movable contact spring portion 51 forms leaf-spring-like by towards length direction rectangular sheet metal being carried out bending machining, can set latch contact site 57 and moving contact portion 56 at free side end, so, the shape of movable connecting elements 50 obtains simplifying, widget processing can be easily carried out, the component costs and the assembly cost of the coaxial connector 1 of belt switch can be further reduced.

Latch contact site 57 does not insert the downside in zone 15 by latch, insert zone 15 but extend to latch, so, even by the space of the height identical with the insertion stroke of latch 100, but also can accommodate movable contact spring portion 51, realize the further low level of the coaxial connector 1 of belt switch.

In the coaxial connector 1 of belt switch,, form the latch introduction part 59 of inserting the outside curve in zone 15 towards latch in the end, latch inserting side of latch contact site 57.In addition, the relative position that latch inserts zone 15 of clamping in the cylinder interior of insulating element 10, form latch and insert guiding wall 17a, 18a, this latch inserts guiding wall 17a, 18a and hangs down towards the latch direction of insertion continuously from the wall surface of the hole of latch patchhole 14.Like this, latch 100 is being guided and is being inserted by latch insertion guiding wall 17a, the 18a that a columnar part forms D shape, so, the axle center of latch 100 can not produce big eccentric or insertion obliquely, and be inserted into the contact surface side of latch contact site 57 reliably by latch introduction part 59 with making latch 100 sliding contacts, can when obtaining high contact reliability, obtain the reliable contact change action of diverter switch 60.
