Description
Technical field
The present invention relates to coaxial connector, particularly relate to a kind of can be to the coaxial connector of the other side's stacker loading and unloading.
Background technology
As the known coaxial connector that has patent documentation 1 to be put down in writing of coaxial connector in the past.Below, Yi Bian with reference to accompanying drawing this coaxial connector is described on one side.Fig. 9 is the sectional structural map of the coaxial connector 101 put down in writing of patent documentation 1.Figure 10 is the profile of the fore-end of coaxial connector 101.The directions of giving prominence to probe 110 in Fig. 9 and Figure 10 are above-below direction.
Top 135 has the drum of open lower side, has taken in helical spring 122 and housing 125 in inside.Sleeve 130 and housing 125 can be along top 135 side slide relative in above-below direction.Yet shown in Fig. 9 (a), housing 125 is contacted bottom 131 by helical spring 122 pushings toward downside usually.Thus, the leading section 126a of housing 125 projects to the outside of cylindrical portion 131a.
As shown in figure 10, the coaxial connector 101 with above-mentioned such formation is assemblied in the other side's stacker 201.The other side's stacker 201 for example is arranged at the antenna of mobile phone and the coaxial connector with switch between transmission circuit, possesses shell 203, external conductor 205, fixed terminal 206 and movable terminal 207.Fixed terminal 206 is connected in antenna, and 207 of movable terminals are connected in transmission circuit.In addition, shown in Figure 10 (a), contact with movable terminal 207 owing to fixed terminal 206 usually, so antenna is connected with transmission circuit.On the other hand, manufacturer shown in Figure 10 (c), will be connected with the hole 204 of probe 110 insertion shell 203 from upside toward downside of tester when the electrical characteristic of the transmission circuit of test mobile phone.Thus, movable terminal 207 is pushed downwards by probe 110.Consequently, fixed terminal 206 separates with movable terminal 207, and probe 110 is connected with movable terminal 207, and transmission circuit and tester are connected.
This explanation coaxial connector 101 be assemblied in the other side's stacker 201 detailed content.Shown in Figure 10 (a), be provided with to the outstanding teat 126b of the center position of this leading section 126a at the front end of the leading section 126a of coaxial connector 101.Thus, the internal diameter of leading section 126a is little than the external diameter of external conductor 205.Yet leading section 126a has it and directly is telescopic structure.Therefore, in the process that the other side's stacker 201 assembles, the inside that external conductor 205 is inserted leading section 126a makes the footpath of leading section 126a shown in Figure 10 (b) more expand than the state of Figure 10 (a) at coaxial connector 101.
By after further thruster is downwards pressed, shown in Figure 10 (c), teat 126b promptly is sticked in the groove 205a that is formed on external conductor 205 peripheries at coaxial connector 101, just and leading section 126a contact the top 205b of external conductor 205.After the reaction force that 205b is produced leading section 126a on the power of being pressed by thruster downwards because of sleeve 130 makes began to shrink required power above helical spring 122, helical spring 122 shrank, and sleeve 130 is with respect to down side slip of housing 125.Thus, leading section 126a is accommodated in the cylindrical portion 131a of bottom 131, and the inner peripheral surface of cylindrical portion 131a is crimped on the outer peripheral face of leading section 126a, makes teat 126b firmly be sticked in groove 205a.Further, be crimped on the outer peripheral face of leading section 126a, prevent to cause leading section 126a plastic deformation because of the footpath overdistension of leading section 126a by the inner peripheral surface of cylindrical portion 131a.
This coaxial connector 101 is such as described below, aspect durability problem is arranged.Particularly, shown in Fig. 9 (b), sleeve 130 is with respect to down side slip of housing 125 when coaxial connector 101 is assemblied in the other side's stacker 201.At this moment, because helical spring 122 is the state that the state than Fig. 9 (a) more shrinks, so housing 125 is pressed by thruster down from helical spring 122 holding capacity.Consequently, the anxiety that can have coaxial connector 101 to come off from the other side's stacker 201 easily because of the power of helical spring 122.
At this problem, in coaxial connector 101, the teat 132b that is arranged at locking plate 132a front end is sticked in the groove 127b that is located at housing 125, to keep the state of Fig. 9 (b).Thus, coaxial connector by the power of helical spring 122, prevents that coaxial connector 101 from returning the state of Fig. 9 (a) from the state of Fig. 9 (b) under the state that is assemblied in the other side's stacker 201.
Yet in coaxial connector 101, as shown in Figure 9, if sleeve 130 slides on above-below direction with respect to housing 125, teat 132b promptly slides on the side of housing 125.If coaxial connector 101 relative the other side's stackers 201 are loaded and unloaded repeatedly, housing 125 and teat 132b just can be subjected to scraping and produce and scrape bits.If this kind scrape bits enter housing 125 and teat 132b between, sleeve 130 just can't slide smoothly.As previously discussed, coaxial connector 101 has problem aspect durability.

(number of assembling steps of coaxial connector)
Then, on one side with reference to Fig. 2 to Fig. 6 the number of assembling steps of coaxial connector 1 is described on one side.Fig. 3 to Fig. 6 is the exploded perspective view of coaxial connector 1.
At first, as shown in Figure 3, from downside helical spring 12 and plunger 11 are inserted tube 13, assembling probe 10.Then, as shown in Figure 4, this probe 10 is inserted the centre bore of insulating case 20 from upside.Then, from upside insulating case 20 is inserted the centre bore of housing 25.Further again, from upside housing 25 is inserted the centre bore of bottom 31.
Then, as shown in Figure 5, cover the top 25a of top 35 with covering shell 25, it is integrated to engage that the end of the downside on top 35 is riveting in the 31b of blade of a sword portion.Here, as shown in Figure 6, with the center conductor 41 (with reference to Fig. 1) of coaxial cable 40, the peristome 29 of 35 peristome 36 and housing 25 inserts from top, is welded in the slot part 13a of tube 13 again.Thus, center conductor 41 promptly pass the tube 13 and helical spring 12 be electrically connected with plunger 11.In addition, make the adapter 43 that is connected with the shielded conductor 42 (with reference to Fig. 1) of coaxial cable 40 be embedded in the peristome 29 of housing 25, ring 44 is riveting in the peripheral part of adapter 43.Thus, shielded conductor 42 promptly passes adapter 43 and is electric conducting state with housing 25.In addition, as shown in Figure 1, be provided with connecting connector 45 (with reference to Fig. 1) in order to be connected to not shown detector at an end of coaxial cable 40.
Then, as shown in Figure 6, magnet 27 is fixed in yoke 23 with binding agent etc.At last, as shown in Figure 6, with disk 21 be loaded into housing 25 above, pass again helical spring 22 make yoke 23 chimeric integrated in top 35 top.
(action of coaxial connector)
The action of coaxial connector 1 then, is described with reference to Fig. 7 and Fig. 8.Fig. 7 is before the assembling of the other side's stacker 201, in the assembling process and the sectional structural map of the fore-end of the coaxial connector 1 after the assembling.Fig. 8 is the sectional structural map of the coaxial connector 1 before and after the assembling of the other side's stacker 201.
At first, describe at the state of coaxial connector 1 before being assemblied in the other side's stacker 201 (below, be called the 1st state).Shown in Fig. 8 (a), disk 21 is urged to downside by helical spring 22.Thus, housing 25 is urged to downside by helical spring 22, the face towards upside of the contact of 25c below the downside blade of a sword 31b of portion of top 25a.Thus, housing 25 is positioned with respect to sleeve 30, and leading section 26a is then from the outstanding length of stipulating of the cylindrical portion 31a of housing 25.
In addition, under the 1st state, the power that disk 21, helical spring 22, magnet 27 and yoke 23 are selected as making power that 22 pairs of housings 25 of helical spring and sleeve 30 produced to be produced greater than 27 pairs of housings 25 of magnet and sleeve 30.Thus, coaxial connector 1 is being unkitted when being assigned in the other side's stacker 201, and leading section 26a is the state that projects to the outside of cylindrical portion 31a, keeps by helical spring 22.
Then, the process that is assemblied in the other side's stacker 201 at coaxial connector 1 describes.The assembling of past the other side's stacker 201 of coaxial connector 1 pushes this top 35 downwards and carries out by holding top 35.Shown in Fig. 7 (a), be provided with toward the outstanding teat 26b of the center position of this leading section 26a at the front end of the leading section 26a of coaxial connector 1.Therefore, the internal diameter of leading section 26a is little than the external diameter of external conductor 205.Yet it is telescopic structure that leading section 26a has its internal diameter.Therefore, coaxial connector 1 in the process of the assembling of the other side's stacker 201, by the inside that external conductor 205 is inserted leading section 26a, shown in Fig. 7 (b), the internal diameter of leading section 26a is promptly more expanded than the 1st state shown in Fig. 7 (a).
By after further thruster is downwards pressed, shown in Fig. 7 (c), the front end of plunger 11 is pressed movable terminal 207 downward thrusters at coaxial connector 1.Thus, fixed terminal 206 just separates with movable terminal 207.Consequently, movable terminal 207 center conductor 41 that promptly passes plunger 11, helical spring 12 and tube 13 and coaxial cable 40 becomes conducting state.
In addition, under the state of Fig. 7 (c), teat 26b is sticked in the groove 205a that is formed on external conductor 205 peripheries, and the top 205b of leading section 26a contact external conductor 205.The reaction force that 205b is produced leading section 26a on the power of being pressed by thruster downwards because of sleeve 30 makes begin to shrink than helical spring 22 required power big after, helical spring 22 shrinks, and sleeve 30 with respect to housing 25 down side slide.Thus, leading section 26a promptly is accommodated in the cylindrical portion 31a of bottom 31, and the inner peripheral surface of cylindrical portion 31a is crimped on the outer peripheral face of leading section 26a, and teat 26b firmly is sticked in groove 205a thus.Further, be crimped on the outer peripheral face of leading section 26a, prevent to cause leading section 26a plastic deformation because of the internal diameter overdistension of leading section 26a by the inner peripheral surface of cylindrical portion 31a.By above action, coaxial connector 1 becomes the state (hereinafter referred to as the 2nd state) that is assemblied in the other side's stacker 201.
But in the coaxial connector 1 of the 2nd state shown in Fig. 8 (b), because helical spring 22 is more the state that shrinks than the 1st state shown in Fig. 8 (a), so housing 25 is pressed by thruster down from helical spring 22 holding capacity.Consequently, the anxiety that can have coaxial connector 1 to come off from the other side's stacker 201 easily because of the power of helical spring 22.
So, be provided with disk 21, helical spring 22, magnet 27 and yoke 23 in the coaxial connector 1, to keep the 2nd state shown in Fig. 8 (b).Particularly, under the 2nd state shown in Fig. 7 (c), sleeve 30 slides into than the lower downside of the 1st state shown in Fig. 7 (a).Therefore, helical spring 22 is the state of contraction, and the end of the downside of yoke 23 contact disk 21.The end contact disk 21 of the downside of yoke 23 makes the housing 25 of the 2nd state be properly oriented with sleeve 30.In addition, because disk 21 and yoke 23 are made of magnetic material, therefore can adsorb each other because of the magnetic force of magnet 27.Here, under the 2nd state, the power that disk 21, magnet 27 and yoke 23 are selected as making power that 27 pairs of housings 25 of magnet and sleeve 30 produced to be produced greater than 22 pairs of housings 25 of helical spring and sleeve 30.Consequently, when coaxial connector 1 is assemblied in the other side's stacker 201, leading section 26a is accommodated in the cylindrical portion 31a, and the state that is restricted because of the footpath expansion of the leading section 26a that inner peripheral surface caused of leading section 26a contact cylindrical portion 31a, keeps by magnet 27.
Then, make coaxial connector 1 when the other side's stacker 201 breaks away from, by with above-mentioned opposite step, just the peripheral part of holding top 35 with finger more up layback open and get final product.After the power that is produced than magnet 27 of the power that the power that top 35 is up drawn and helical spring 22 desires are upheld big with withing joint efforts, sleeve 30 i.e. side shifting up, and releasing disk 21 contacts with yoke 23.Thus, because the absorption affinity of 27 pairs of disks 21 of magnet dies down, so the power that helical spring 22 is produced is promptly big than the power that magnet 27 is produced.Therefore, the 31b of blade of a sword portion of bottom 31 is just by helical spring 22 side shifting up, and up side shifting to butt housing 25 till the 25c.At this moment, because leading section 26a projects to the outside of cylindrical portion 31a, so leading section 26a is disengaged with contacting of cylindrical portion 31a and the expansion of the footpath of this leading section 26a.Thus, teat 26b promptly breaks away from from groove 205a.Then, in the other side's stacker 201, movable terminal 207 promptly because of the past upside displacement of the elasticity of itself, is returned to the connection status with fixed terminal 206.
Then, at external conductor 205 being inserted the required power F1 of leading section 26a, describing in the relation of the power F4 that makes helical spring 22 shrink required power F2, helical spring 22 is produced under the state of Fig. 8 (b) power F3 under the state of Fig. 8 (a) and produced at the state lower magnet 27 of Fig. 8 (b).
At first, when coaxial connector 1 is assemblied in the other side's stacker 201, the user must with the power more than the power F1 with sleeve 30 down thruster press.Thus, external conductor 205 is inserted leading section 26a.In addition, the size of power F2 must be big than power F1.When the size of power F2 than power F1 hour, external conductor 205 is inserted leading section 26a before, helical spring 22 shrink and sleeve 30 down side slide.At this moment, coaxial connector 1 can't be assemblied in the other side's stacker 201.At this, this case inventor is 4N with the size that coaxial connector 1 is designed to power F1, and the size of power F2 is 5N.
After externally conductor 205 inserts leading section 26a, the user with the power more than the power F2 with sleeve 30 down thruster press.Thus, helical spring 22 shrinks and leading section 26a just is accommodated in the cylindrical portion 31a, and coaxial connector 1 is assemblied in the other side's stacker 201.
On the other hand, when the other side's stacker 201 broke away from, the user must up draw sleeve 30 with the power bigger than the difference of power F4 and power F3 with coaxial connector 1.Thus, the power F4 that is produced than magnet 27 with joint efforts of power F3 that helical spring 22 is produced and user's power is big, and disk 21 separates with yoke 23.So coaxial connector 1 breaks away from from the other side's stacker 201.The present inventor becomes 7N with the size design of power F3, and the size design of power F4 is become 9N.Thus, the user can make coaxial connector 1 break away from from the other side's stacker 201 by applying the power more than the 2N.
(effect)
According to the coaxial connector 1 that constitutes in the above described manner, such as described below, compare with coaxial connector 101 and can obtain increased durability.Particularly, in the coaxial connector 101, as shown in Figure 9, because teat 132b slides with respect to housing 125, therefore if repeat coaxial connector 101 is loaded and unloaded on the other side's stacker 201, teat 132b or housing 125 just can be subjected to scraping and produce and scrape bits.This kind chip can enter teat 132b and housing 125 between, and hinder the smooth slip of sleeve 130.
In addition, if teat 132b slides with respect to housing 125, teat 132b and groove 127a, 127b can be subjected to scraping.Therefore, teat 132b just can't firmly engage with groove 127a, 127b.As previously discussed, coaxial connector 101 has the problem of durability.
On the other hand, shown in Fig. 8 (b), in coaxial connector 1, housing 25 is pulled up to upside, is equipped with the 2nd state of the other side's stacker 201 to keep assembling by magnet 27.Therefore, when coaxial connector 1 is loaded and unloaded on the other side's stacker 201 because housing 25 slides hardly with sleeve 30, thus housing 25 and sleeve 30 between can not produce and scrape bits.Therefore, even coaxial connector 1 is loaded and unloaded on the other side's stacker 201 repeatedly, also can not hinder the smooth slip of sleeve 30.According to the above, compare with coaxial connector 101, utilize coaxial connector 1 can obtain higher durability.
In addition, the inventor makes coaxial connector 1,101, and carries out the durable test of this coaxial connector 1,101.Known coaxial connector 101, when being coated with wax between teat 132b and housing 125, the loading and unloading about 10000 times can produce bad, and when not being coated with wax between teat 132b and housing 125, the loading and unloading about 300 times promptly produce bad.On the other hand, coaxial connector 1 has confirmed to tolerate more than 20000 times relatively that the other side's stacker 201 loads and unloads.According to more than, by durable test, coaxial connector 1 has higher durability compared to coaxial connector 101 as can be known.
In addition, in coaxial connector 101, between teat 132b and housing 125, must be coated with wax to promote durability.Yet, in coaxial connector 1, under the state that housing 25 and sleeve 30 are pushed, do not slide, therefore do not need wax.
In addition, shown in Fig. 8 (b), in coaxial connector 1, be assemblied in the 2nd state of the other side's stacker 201, disk 21 contacts with yoke 23, and disk 21 does not then contact with magnet 27.Thus, such as described below, housing 25 stably adsorbs with sleeve 30.
Particularly, disk 21 and yoke 23 are made of ferromagnetism body material.Therefore, shown in Fig. 8 (b), if disk 21 contacts with yoke 23, just can produce magnetic flux shown in arrow φ.At this moment, when magnet 27 contact disks 21, disk 21 and yoke 23 the strongest absorption.Therefore, be preferably disk 21 and contact, and disk 21 also contacts with magnet 27 with yoke 23.On the other hand, if disk 21 do not contact with yoke 23, the absorption affinity of the absorption affinity of disk 21 and 23 of yokes when disk 21 contacts with yoke 23 is minimum.Even gapped between magnet 27 and disk 21, as long as disk 21 contacts with yoke 23, absorption affinity only reduces a little, and this absorption affinity is more stable.
In the product of reality, magnet 27 passes binding agent and is fixed in yoke 23, and the deviation of this adhesive thickness can cause the following position of magnet 27 to produce deviation.In addition, the surface accuracy of the magnet 27 through burning till is not good, and this precision also can cause the following position of magnet 27 to produce deviation.As above-mentioned, because of manufacture deviation etc. is difficult to manufacture disk 21 is contacted with yoke 23, and disk 21 and magnet 27 state of contact.Therefore, consider the deviation of binding agent and the surface accuracy of magnet 27, and gap a little is set below magnet 27 and between the disk 21, and set the size of disk 21, yoke 23 and magnet 27, so that disk 21 fully contacts with yoke 23.Magnet 27 carries out high-precision attrition process to reduce its deviation.By between magnet 27 and disk 21, the gap being set, then also need not carry out high-precision attrition process.
In addition, in the coaxial connector 1, magnet 27 is arranged to be positioned at helical spring 22.Therefore, coaxial connector 1 can be sought miniaturization compared to the coaxial connector that magnet is arranged at outside the helical spring.
(other execution mode)
In addition, coaxial connector is not limited to the coaxial connector 1 of above-mentioned execution mode, can do various changes in the scope of its main idea.
In coaxial connector 1, though yoke 23 and magnet 27 are installed on sleeve 30, and disk 21 is installed on housing 25, the installation site of yoke 23, magnet 27 and disk 21 is not limited to this.For example, also yoke 23 and magnet 27 can be installed on housing 25, and disk 21 is installed on sleeve 30.Yet,, therefore be preferably yoke 23 and magnet 27 be installed on sleeve 30, and disk 21 is installed on housing 25 because it is simple than yoke 23 cylindraceous is pressed into housing 25 that flat disk 21 is pressed into housing 25.
In addition, magnet also can be set to replace disk 21.
In addition, in coaxial connector 1, though helical spring 22 is provided with their also separable settings with magnet 27 is approaching.
In addition, under the state of Fig. 7 (c),, might not be accommodated in fully in the cylindrical portion 31a though leading section 26a is accommodated in the cylindrical portion 31a fully.When externally the footpath of conductor 205 was big, the footpath of leading section 26a may significantly be expanded, and leading section 26a can't be accommodated in the cylindrical portion 31a fully.Therefore, as long as at least a portion of leading section 26a is accommodated in cylindrical portion 31a.
Utilizability on the industry
As mentioned above, the present invention is useful aspect coaxial connector, particularly can obtain to have aspect the coaxial connector of excellent durability better.
