(inspection is with the action of coaxial connector)
Next, with reference to Fig. 7 and Fig. 8 the action of inspection with coaxial connector 1 described.Fig. 7 be before assembling as seized object socket 201 of having a medical check-up, assembling midway and the inspection after the assembling with the insight structural map of the fore-end of coaxial connector 1.Fig. 8 is that inspection before and after the assembling to object socket 201 is with the insight structural map of coaxial connector 1.
At first, inspection being assemblied in before state of object socket 201 (below, be called first state) with coaxial connector 1 describes.Shown in Fig. 8 (a), absorption ring 22 contacts with magnet 28.Thus, absorption ring 22 is adsorbed on magnet 28.Then, because absorption ring 22 is installed in housing 25, so housing 25 utilizes the absorption affinity between absorption ring 22 and the magnet 28 and attracted to downside.As a result, the lower surface 25c towards downside of top 25a contacts with the face towards upside of flange part 31b.Thus, housing 25 is positioned with respect to sleeve 30, and leading section 26a is from the amount of the length of the outstanding regulation of cylindrical portion 31a of sleeve 30.
In addition, under first state, the power that applies with 28 pairs of housings 25 of magnet and sleeve 30 is than the big mode of power that 27 pairs of housings 25 of magnet and sleeve 30 apply, selector disc 21, absorption ring 22, magnet 27 and yoke 23.Thus, be not assemblied under the situation of object socket 201 with coaxial connector 1, utilize magnet 28 and absorption ring 22 to keep leading section 26a to be projected into the state of the outside of cylindrical portion 31a in inspection.
Next, to checking that the process that is assemblied in object socket 201 with coaxial connector 1 describes.Inspection is carried out through pinching top 35 and pressing down this top 35 with the assembling of coaxial connector 1 to object socket 201.Shown in Fig. 7 (a), be provided with to the outstanding jut 26b of the center position of this leading section 26a at the front end of inspection with the leading section 26a of coaxial connector 1.Therefore, the internal diameter of leading section 26a forms forr a short time than the external diameter of external conductor 205.But leading section 26a has the telescopic structure of internal diameter of this leading section 26a.Therefore,, be inserted into the inside of leading section 26a through external conductor 205 in inspection with coaxial connector 1 to the assembling of object socket 201 midway, shown in Fig. 7 (b), the internal diameter of leading section 26a is wideer than first state shown in Fig. 7 (a).
And then, when inspection with coaxial connector 1 quilt when downside presses down, shown in Fig. 7 (c), the front end of plunger 11 presses down movable terminal 207 towards downside.Thus, fixed terminal 206 separates with movable terminal 207.As a result, movable terminal 207 becomes via plunger 11, helical spring 12 and plunger bushing 13 state with center conductor 41 conductings of coaxial cable 40.
In addition, under the state of Fig. 7 (c), jut 26b engages with the groove 205a of the periphery that is formed at external conductor 205, and leading section 26a contacts with the upper surface 205b of external conductor 205.When utilizing the power that presses down sleeve 30 towards downside; When the repulsion that upper surface 205b applies leading section 26b becomes bigger than the absorption affinity between absorption ring 22 and the magnet 28; Absorption ring 22 separates with magnet 28, and sleeve 30 breaks away down with respect to housing 25 and moves, and disk 21 is adsorbed on yoke 23.Thus, be incorporated in through leading section 26a in the cylindrical portion 31a of bottom 31, the inner peripheral surface of cylindrical portion 31a is crimped on the outer peripheral face of leading section 26a, and jut 26b engages with groove 205a securely.And then, be crimped on the outer peripheral face of leading section 26a through inner peripheral surface with cylindrical portion 31a, prevent the internal diameter overdistension of leading section 26a and cause leading section 26a that plastic deformation takes place.According to above action, inspection is adsorbed on yoke 23 with coaxial connector 1 through disk 21, and maintenance is assemblied in the state (below, be called second state) of object socket 201.
Next, under the situation that inspection is broken away from from object socket 201 with coaxial connector 1, according to above-mentioned opposite order, that is, utilize to point to pinch the peripheral part on top 35 and extract to get final product towards upside.When the power that promotes top 35 became bigger than the power that is produced by magnet 27, sleeve 30 is side shifting up, and the absorption between disk 21 and the yoke 23 is disengaged.Then, the flange part 31b of bottom 31 because of inertia force up side shifting up to the lower surface 25c butt of housing 25 till.And then absorption ring 22 contact with magnet 28, adsorb encircle 22 and magnet 28 between produce absorption affinity.At this moment, because leading section 26a is outstanding towards the outside of cylindrical portion 31a, so contacting between leading section 26a and the cylindrical portion 31a is disengaged, the diameter of this leading section 26a broadens.Thus, jut 26b breaks away from from groove 205a.Then, in object socket 201, movable terminal 207 towards the upside displacement, returns to the connection status with fixed terminal 206 by self elasticity.
Next, external conductor 205 is inserted into the needed power F1 of leading section 26a, describes at power F2 that the state lower magnet 28 of Fig. 8 (a) is produced and the relation between the power F3 that the state lower magnet 27 of Fig. 8 (b) is produced.
At first, when inspection was assemblied in object socket 201 with coaxial connector 1, the user need push sleeve 30 with the power more than the power F1 towards downside.Thus, external conductor 205 is inserted into leading section 26a.In addition, the size of power F2 needs specific force F1 big.Under the little situation of the big or small specific force F1 of power F2, externally conductor 205 is inserted into before the leading section 26a, and magnet 28 is disengaged with the absorption of absorption ring 22, and this is moving cause because sleeve 30 breaks away down.In this case, can't inspection be assemblied in object socket 201 with coaxial connector 1.Therefore, the application inventor has designed inspection with coaxial connector 1, is 4N with the size of the F1 that exerts all one's strength, and the size of power F2 is 6N.
When external conductor 205 was inserted into leading section 26a, the user pushed sleeve 30 with the power more than the power F2 towards downside.Thus, the absorption between absorption ring 22 and the magnet 28 is disengaged, and leading section 26a is incorporated in the cylindrical portion 31a, and inspection is assemblied in object socket 201 with coaxial connector 1.
On the other hand, with coaxial connector 1 during from object socket 201 disengagings, the user need be with the big power of specific force F3 towards upside lift lug tube 30 in inspection.Thus, the power F3 that is produced with magnet 27 compares, and it is big that the power of user's lifting becomes, and the absorption between disk 21 and the yoke 23 is disengaged.Then, inspection breaks away from from object socket 201 with coaxial connector 1.The application inventor designs with the mode that the size of power F3 becomes 3N.Thus, the user can break away from coaxial connector 1 inspection through applying the power more than the 3N from object socket 201.
In addition, inspection with coaxial connector 1 in, under first state, the power (that is, power F2) that 28 pairs of housings 25 of magnet and sleeve 30 apply, than under second state, the power (that is power F3) that applies of 27 pairs of housings 25 of magnet and sleeve 30 greatly.Specifically, power F2 is set to 6N, and power F3 is set to 3N.
(effect)
,, as following explanation, compare with coaxial connector 1 according to above such inspection that constitutes, can access high-durability with coaxial connector 101.In more detail, as shown in Figure 9 in coaxial connector 101, because jut 132b slides with respect to housing 125, so when carrying out coaxial connector 101 to the loading and unloading of object socket 201 repeatedly, jut 132b, housing 125 are produced smear metal by grinding.Such smear metal enters between jut 132b and the housing 125, hinders the slip smoothly of sleeve 130.
And then when jut 132b slided with respect to housing 125, jut 132b and groove 127a, 127b were by grinding.Therefore, can not engage strong between jut 132b and groove 127a, the 127b.As stated, coaxial connector 101 has problems aspect durability.
In addition, in checking, shown in Fig. 8 (b),, utilize magnet 27 to promote housing 25 towards upside in order to keep being assemblied in second state of object socket 201 with coaxial connector 1.Therefore, checking with coaxial connector 1 when object socket 201 loads and unloads, owing to housing 25 and sleeve 30 slide hardly, so between housing 25 and sleeve 30, do not produce smear metal.Therefore, even if inspection is loaded and unloaded with respect to object socket 201 with coaxial connector 1 repeatedly, can not hinder the slip smoothly of sleeve 30 yet.According to the above,, compare with coaxial connector 1 according to inspection with coaxial connector 101, can access high-durability.
In addition, the application inventor makes inspection with coaxial connector 1 and coaxial connector 101, has carried out the long duration test of inspection with coaxial connector 1 and coaxial connector 101.In coaxial connector 101 in the past; Under the situation of coating of wax between jut 132b and the housing 125; After the loading and unloading about 10000 times, produce undesirable condition,, after the loading and unloading about 300 times, produce undesirable condition between jut 132b and the housing 125 not under the situation of coating of wax.On the other hand, confirmed that inspection can bear more than 20000 times the loading and unloading to object socket 201 with coaxial connector 1.According to the above,, can know that inspection compares with coaxial connector 101 with coaxial connector 1 and to have high-durability according to long duration test.
In addition, in coaxial connector 101, in order to improve durability, need be between jut 132b and housing 125 coating of wax.Yet, in checking, owing to housing 25 and sleeve 30 do not slide under the state of being pressed, so do not need wax with coaxial connector 1.
In addition, in checking with coaxial connector 1, shown in Fig. 8 (b), be assemblied under second state of object socket 201, disk 21 contacts with yoke 23, and disk 21 does not contact with magnet 27.Thus, as following explanation, housing 25 stably adsorbs with sleeve 30.
In more detail, disk 21 and yoke 23 are made up of ferromagnetism body material.Therefore; Shown in Fig. 8 (b); When disk 21 contacts with yoke 23, produce the magnetic flux shown in arrow
.In this case, when magnet 27 contacted with disk 21, disk 21 was adsorbed with yoke 23 the most powerfully.Therefore, preferred disk 21 contacts with yoke 23, and disk 21 contacts with magnet 27.On the other hand, when disk 21 did not contact with yoke 23, the absorption affinity between disk 21 and the yoke 23 was compared with the absorption affinity of the situation that disk 21 contacts with yoke 23, diminishes to heavens.Even if between magnet 27 and disk 21, have the gap, if disk 21 contacts with yoke 23, then absorption affinity also just reduces a little, and in addition, this absorption affinity is stable.
In the product of reality, magnet 27 is fixed in yoke 23 via adhesive, and according to the deviation of the thickness of this adhesive, the position of the lower surface of magnet 27 produces deviation.In addition, the surface accuracy of the magnet 27 that sintering finishes is low, causes the position of the lower surface of magnet 27 that deviation takes place because of this precision.Like this, according to manufacture deviation etc., be difficult to form that disk 21 contacts with yoke 23 and disk 21 and magnet 27 state of contact.Thereby the mode that fully contacts with disk 21 and yoke 23 is considered the deviation of adhesive, the surface accuracy of magnet 27, between the lower surface of magnet 27 and disk 21, small gap is set, the size of setting disk 21, yoke 23 and magnet 27.Through being carried out high-precision attrition process, magnet 27 reduces this deviation.Through between magnet 27 and disk 21, the gap being set, need not carry out high-precision attrition process etc.
In addition, in checking, as following explanation, can use the more weak magnet of magnetic force 27 with coaxial connector 1.In more detail, for example, inspection with coaxial connector 1 in, replace absorption ring 22 and magnet 28, consider use helical spring 122 as shown in Figure 9 (below, the inspection that helical spring 122 is applied to is called comparative example with coaxial connector 1).In this comparative example, under second state shown in Fig. 8 (b), helical spring 122 forms the state of contraction.Therefore, in comparative example, under second state, need adsorb disk 21 and magnet 27, so that disk 21 is not easy to separate because of the power that helical spring 122 is intended to extend with magnet 27.Therefore, in comparative example, need to use the magnet 27 of the big high price of magnetic force.
In addition, inspection with coaxial connector 1 in, under second state, absorption encircles 22 and separates with magnet 28.Therefore, between absorption ring 22 and magnet 28, act on absorption affinity hardly.Therefore, in checking with coaxial connector 1, compare with comparative example, the absorption affinity between disk 21 and the magnet 27 also can be less.Therefore, in checking, can use the magnet 27 of the little low price of magnetic force with coaxial connector 1.
In addition, in checking with coaxial connector 1, as following explanation, design becomes easy.In more detail, in above-mentioned comparative example, under second state, because helical spring 122 contractions, so be intended to separate disk 21 and magnet 27.The power absorption disk 21 and magnet 27 of the degree that therefore, need be not easy to separate with disk 21 and magnet 27 because of the power that helical spring 122 is intended to extend.Therefore, in comparative example, need under the situation of considering the power that helical spring 122 is intended to extend, design disk 21 and magnet 27.
On the other hand, inspection with coaxial connector 1 in, under second state because absorption ring 22 separates with magnet 28, so adsorb encircle 22 and magnet 28 between act on absorption affinity hardly.Thereby, in checking, can not consider the power that helical spring 122 is intended to extend and adsorb the absorption affinity between ring 22 and the magnet 28, design disk 21 and magnet 27 with coaxial connector 1.Therefore, in checking with coaxial connector 1, design becomes easy.
In addition, in checking, as following explanation, improve durability with coaxial connector 1.More particularly, in coaxial connector as shown in Figure 9 101, helical spring 122 stretches to 201 loading and unloading of object socket the time repeatedly.Therefore, little by little plastic deformation and following the string of helical spring 122.On the other hand, in checking, replace helical spring 122, use absorption ring 22 and magnet 28 with coaxial connector 1.Because use permanent magnet as magnet 28, so even if use all the year round, the magnetic force of magnet 28 also reduces hardly.Therefore, in checking with coaxial connector 1, compare with coaxial connector 101 as shown in Figure 9, the size of loading and unloading needed power to object socket 201 can not change because of use repeatedly.That is, inspection is compared with coaxial connector 101 with coaxial connector 1 and is had high-durability.
In addition, inspection with coaxial connector 1 in, under first state, the power that 28 pairs of housings 25 of magnet and sleeve 30 apply, than under second state, the power that applies of 27 pairs of housings 25 of magnet and sleeve 30 is big.Thus, the power when inspection is assemblied in object socket 201 with coaxial connector 1, the power during from 201 disengagings of object socket is big with coaxial connector 1 than inspection.Therefore, the user can be pressed into object socket 201 through checking with coaxial connector 1 with big relatively power, will check with coaxial connector 1 and be assemblied in object socket 201 while can experience the situation of being pressed into.In addition, the user can make inspection break away from from object socket 201 with coaxial connector 1 with relatively little power simply.
(other execution mode)
In addition, inspection is not limited to the related inspection of above-mentioned execution mode with coaxial connector 1 with coaxial connector, can in the scope of its purport, carry out various changes.
In checking with coaxial connector 1, though yoke 23 and magnet 27 are installed, disks 21 are installed at housing 25 at sleeve 30, the installation site of yoke 23, magnet 27 and disk 21 is not limited thereto.For example, also can yoke 23 and magnet 27 be installed, disk 21 be installed at sleeve 30 at housing 25.But,,, disk 21 is installed at housing 25 so preferably yoke 23 and magnet 27 are installed at sleeve 30 because it is simpler than yoke 23 cylindraceous is pressed into housing 25 that flat disk 21 is pressed into housing 25.
In addition, inspection with coaxial connector 1 in, at sleeve 30 magnet 28 are installed, at housing 25 absorption ring 22 is installed, but absorption encircle 22 and the installation site of magnet 28 be not limited thereto.For example, also can magnet 28 be installed, absorption ring 22 be installed at sleeve 30 at housing 25.
In addition, also can replace disk 21 and absorption ring 22 and magnet is set.
In addition, in checking with coaxial connector 1, disk 21 more closely is provided with magnet 27, but disk 21 also can remotely be provided with magnet 27.
In addition, under the state of Fig. 7 (c), leading section 26a fully is accommodated in the cylindrical portion 31a, but is not fully to be accommodated in the cylindrical portion 31a.Under the situation that externally diameter of conductor 205 is big, exist the diameter of leading section 26a significantly to expand, leading section 26a fully is not accommodated in the situation in the cylindrical portion 31a.Therefore, as long as at least one of leading section 26a is incorporated in cylindrical portion 31a.
