Then, the wearing or featuring stage armour gripping member is controlled clip 130 and is inserted in the clip master resettlement section 154 of shell 151.Then will insert clip main body 131 with joint 101 with the coaxial connector of coaxial cable 120.Then, as shown in Figure 7, the anchor portion of casing cover 132 is bent, and clip lid 132 falls to 131 1 inclinations of clip main body whereby.Therefore, because clip lid 132 is closed, coaxial connector is covered by clip lid 132 with the top of joint 1.After this, as shown in Figure 1, coaxial cable 120 inserts between the last facial 16a and machined surface 3a of cable pressing plate 16.Then, the whole coaxial cable 120 on the machined surface 3a is accommodated in the cable accepting portion 14.
Whereby, because coaxial cable 120 is accommodated in the cable accepting portion 14, so coaxial cable 120 can be not easy hand that tangles the operator etc. during operation afterwards.And then, even tangle the occasion of operator's hand etc. at coaxial cable 120, also because cable pressing plate 16 is configured to covering cable resettlement section 14, so prevent coaxial cable 120 coming off from cable accepting portion 14.As a result, move when the operation, prevent the machining state collapse such problem of coaxial connector with joint 101 or clip 130, shell 151 by coaxial cable 120.
(casing cover is toppled over operation)
As mentioned above, part is placed operation one and is finished, and the fixed mechanism main body 21 of shell fixed mechanism 18 is just rotated towards shell maintaining part 4 directions.Then, shown in Fig. 6 (a), the operator pushes mobile screw 23 towards shell maintaining part 4 directions, and the leading section 19a that is located at the shell fixed component 19 on the other end of fixed mechanism main body 21 whereby is connected on the internal face of connecting portion 153a (anchor portion) of the casing cover 153 that is placed on the shell maintaining part 4.
In addition, when the leading section 19a of shell fixed component 19 was connected on the connecting portion 153a, the lower surface of shell fixed component 19 just was connected on the upper surface of housing main body 152.Therefore, owing to housing main body 152 outer shell fixed components 19 are pushed down, so the placement of the machining state of shell 151 becomes more reliable.
After this, as shown in Figure 2, control member 12 and upwards rotate from the diagram solid line position, casing cover pushing member 8 advances towards fixed mechanism main body 21 directions.Then, as shown in Fig. 6 (a), the outside wall surface abutting part 8a of casing cover pushing member 8 is connected on the outside wall surface of casing cover 153.At this moment, casing cover pushing member 8 tilts, so that the upper face side of outside wall surface abutting part 8a more approaches casing cover 153 than following side.Thereby, when outside wall surface abutting part 8a is connected on the outside wall surface of casing cover 153 and pushes, give pushing force to the upper portion (leaving the part of connecting portion 153a) of casing cover 153 at the butt initial stage.As a result, the big distance of the upper portion of connecting portion 153a and casing cover 153 causes the generation of big moment, in addition, because the outer shell fixed component 19 of the internal face of connecting portion 153a supports, so to be easy to connecting portion 153a be that bending point is toppled over to casing cover 153.
After this, shown in Fig. 6 (a) and (b), if casing cover 153 topple over big angle, Yi Bian then the lower portion of the outside wall surface abutting part 8a of casing cover pushing member 8 on one side planar ground butt casing cover 153 push.As a result, problems such as bending in the toppling process of casing cover 153 have fully been prevented.In addition, in the toppling process of casing cover 153, the shell fixed component 19 of toppling over side that is disposed at casing cover 153 becomes thickness at the thinnest state of the connecting portion 153a of casing cover 153 side.Whereby, because supporting on one side, the outer shell fixed component 19 in casing cover 153 one side toppled over up to becoming enough big dump angle, so toppling over of casing cover 153 becomes reliable.
And then, support towards the pushing of turnover direction with pushing force by the operator from the shell fixed component 19 of internal face side bearing casing cover 153 greater than the loading force of the 1st spring member 25.Thereby, if the operator weakens pushing force along with toppling over of casing cover 153, while then shell fixed component 19 is connected on the casing cover 153 by the loading force of the 1st spring member 25 and slowly retreats.As a result, though the leading section 19a out of plumb of shell fixed component 19 be connected to the connecting portion 153a of casing cover 153, also can carry out toppling over of casing cover 153 reliably.
If casing cover 153 is poured into the big dump angle (for example from 60 ° of vertical direction) of regulation, the rising of controlling member 12 of Fig. 2 is stopped, the turnover of casing cover pushing member 8 temporarily stops whereby.Then, the operator is by removing pushing, and shown in Fig. 6 (d), shell fixed component 19 leaves the connecting portion 153a of casing cover 153 by the loading force of the 1st spring member 25.After this, Fig. 2 controls the position that member 12 rises to illustrated double dot dash line, and the turnover of casing cover pushing member 8 begins once more.Whereby, casing cover 153 is poured into and is contacted with housing main body 152, and the lower surface of casing cover 153 by outer wall abutting part 8a 152 pushings form state for the state that stands vertically that is difficult to recover original to housing main body.After this, as shown in Figure 1, fixed mechanism main body 21 backward rotation turn back to the holding fix that illustrates solid line.
Moreover, though in the present embodiment, implement the yielding of shell fixed component 19 by the turnover that temporarily stops casing cover pushing member 8 and move, also can carry out continuously.
(interim fastening operation)
Next, as shown in Figure 1, push down the state of casing cover 153, Yi Bian make interim retention mechanism 28,28 actions Yi Bian keep by casing cover pushing member 8.That is to say that the interim anchorage bar mobile member of two of interim retention mechanism 28,28 30,30 is controlled by the operator, rotates towards base plate 1 direction.Whereby, as shown in Figure 3, two interim anchorage bar mobile members 30,30 make interim anchorage bar 29,29 move towards the interim fastening direction as shell maintaining part 4 directions, and leading section 29b, the 29b of interim anchorage bar 29,29 enter in the 2nd casing cover resettlement section 4c whereby.At this moment, before interim anchorage bar 29,29 turnover in the 2nd casing cover resettlement section 4c, by the action of toppling over of above-mentioned casing cover 153, the both ends of the 2nd cap 153c of Fig. 7 exist.As a result, the both ends of the 2nd cap 153c push from the outside by interim anchorage bar 29,29 with sandwiching, make the both ends of the 2nd cap 153c change the fastening temporarily of clip pair resettlement section 155 over to whereby.Moreover, if carry out fastening temporarily, then because the position of clip 130, joint 101 and coaxial cable 120 in shell 151 concerns almost fixed, so also do not produce location dislocation even give how much external force.
(discharge operation)
Interim fastening one finishes, and interim anchorage bar mobile member 30,30 just becomes free state.Whereby, interim anchorage bar mobile member 30,30 retreats by the loading force of the 2nd spring member 31,31, and the leading section of interim anchorage bar mobile member 30,30 is made a concession from the 2nd casing cover resettlement section 4c.In addition, as shown in Figure 1, control member 12 and drop to solid line position from the double dot dash line position of Fig. 2, casing cover pushing member 8 leaves shell maintaining part 4, and open the top of shell maintaining part 4 whereby.
After this, as shown in Figure 4, push 35 persons of being operated that handle knob and control, by pushing towards base plate 1 direction, shell is discharged bar 34 and is pushed in the shell tap 3c.As a result, be bearing in shell and discharge shell on the Horizontal Branch bearing surface 34a of bar 34 and discharge member 40 and rise along sloping bearing surface 34b, be positioned over whereby this shell discharge member 40 the top shell 151 by on lift and discharge from shell maintaining part 4.
After this, interim fastening shell 151 persons of being operated control, and are transplanted on the formal fastening operation of next process.Then, in this formal fastening operation, as shown in Figure 7, crimping is carried out by abundant bending in the both ends that cover the 2nd cap 153c of insulator 124, and shielded conductor 123 and crust 122 are being pressed conductor pressure contact portion 153d and crust pressure contact portion 153e respectively, make coaxial connector 161 whereby.
As above, the shell clamp for machining of present embodiment is that processing has the housing main body 152 that the clip 130 of joint 101 of accommodating band coaxial cable 120 is installed, upright with a side at this housing main body 152, the clamp for machining of the shell 151 of the casing cover 153 of the upper surface by sealing this housing main body 152 to the opposing party's inclination, be taken as and comprise having flat machined surface 3a and make casing cover 153 relative this machined surface 3a quadratures, shell 151 is held in from the base plate 1 of the shell maintaining part 4 of a side direction opposite side of housing main body 152 machining state consistent with press direction, and the casing cover 153 that makes the shell 151 that remains in shell maintaining part 4 makes the formation of its bending mechanism of toppling over 5 to the press direction pushing.
If with above-mentioned formation, then as long as shell 151 is positioned on the shell maintaining part 4 of base plate 1, even the positioning accuracy when placing shell 151 is low, also can make from a side direction opposite side of housing main body 152 machining state consistent and place shell 151 with the machined surface 3a quadrature of casing cover 153 relative base plates 1 with press direction.And, on one side can keep this machining state, Yi Bian make it to topple over towards press direction pushing casing cover 153 by bending mechanism 5.Whereby, become simple to the placement operation of the machining state of casing cover 153 and the operation of toppling over of casing cover 153.
In addition, if carry out placement operation to the shell 151 of shell maintaining part 4 by the operator, then at least in the connector assembling operation that casing cover 153 is toppled over, the operator there is no need with for example clamp shell 151 to be remained in machining state.Whereby, because can make the focusing on the assembling operation of connector of operator, thus can prevent the dislocation of the position relation of each part, and can alleviate operator's burden.As a result, can boost productivity and rate of finished products, particularly can improve significantly in the occasion that minimum shell 151 is installed.
