Fig. 8 has represented employed securing rod 60 in connector shown in Figure 7, and Fig. 8 A is its vertical view, and Fig. 8 B is the front view (from the side view of downside 8A with the aid of pictures) of Fig. 8 A, and Fig. 8 C is the left view of Fig. 8 A, and Fig. 8 D is the right view of Fig. 8 A.
As shown in Figure 8, the rearward end of the elongated securing rod 60 of reservation shape constitutes and is formed on the holding section 63 that side that the square through hole 12 on the above-mentioned metallic sheath 10 fastens roughly is the L font, this holding section 63, as can understanding, roughly bend rectangular kink 64 downwards and rearward turn back and formed with the roughly rectangular return portion 65 of this kink 64 by rear end from base portion 62 from Fig. 8 B.The front end of base portion 62 becomes crooked bend 66 downwards, forms first rake 67B that tilts continuously and upward with this bend 66 and the second rake 67F that tilts equally upward.Top ends at the second rake 67F forms two outstanding upward pawls 61, and the tip side end face of these pawls 61 is formed on the inclined plane of tilted rearward, and this rear end side end face is formed on vertical plane or stretches out on the face.In this embodiment, with the first continuous rake 67B of bend 66, its tilt angle theta is bigger slightly than the angle of inclination of the second rake 67F with pawl 61.
The securing rod 60 of above-mentioned formation can form by for example the long and thin metal plate (metal strip) of reservation shape being carried out needed bending machining.Example to the processing method of this securing rod 60 describes below.
At first, prepare the metal strip of predetermined length, have two protuberances of the roughly trapezoidal shape of on Width, giving prominence to symmetrically laterally from two sides of top ends.The width of this metal strip roughly is certain except its top ends, and its thickness roughly is certain along total length.The protuberance of outstanding roughly trapezoidal shape symmetrically laterally from two sides of top ends, as can understand from Fig. 8 B, the end face of tip side is formed on the wall of tilted rearward, and the end face of rear end side is formed on vertically or on the wall that stretches out.
By bend up these from two sides of top ends laterally symmetrically the protuberance of outstanding roughly trapezoidal shapes and on the top ends of metal strip, form two roughly upright pawls 61 so that be in contact with one another.Then, the rear end side of metal strip downwards (direction opposite) with the vertical direction of pawl 61 roughly be bent into the right angle, form kink 64, approximate right angle is rearward turned back in the rear end of this kink 64, form return portion 65.Thus, form and be formed on the holding section 63 that side that the square through hole 12 on the metallic sheath 10 fastens roughly is the L font.
Remain the base portion 62 of the predetermined length of general planar in the front of kink 64, the crooked downwards predetermined length in the front portion of this base portion 62, and formation bend 66, the front portion of this bend 66 is tilted upward, form the first rake 67B of tilt angle theta, simultaneously, from bend 66 on the predetermined length position of tip side, this first rake 67B small angle of turning back, form the second slightly little rake 67F of inclination angle.Like this, form with the continuous first rake 67B of bend 66 and with this first rake 67B continuously and on the top, have second a rake 67F of pawl 61.
The securing rod 60 of Xing Chenging like this, inserted, be engaged in the square through hole 12 that is formed on the metallic sheath 10 by the holding section 63 that makes its rear end, and installed with the state that is projected on metallic sheath 10 fitting portions 11 outer peripheral faces at the pawl 61 on the top of the second rake 67F.
Fig. 9 represents state that the metallic sheath 10 that uses in securing rod shown in Figure 8 60 and the connector shown in Figure 7 is fastened, and Fig. 9 A is its vertical view, Fig. 9 B be along the 9B-9B line cut off Fig. 9 A and on the direction of arrow seen cutaway view.And in Fig. 9, metallic sheath 10 only illustrates the part that securing rod 60 is installed.
As shown in Figure 9, when leading to, being fastened in square (the being rectangle in this embodiment) through hole 12 that is formed on the metallic sheath 10 when the holding section 63 of securing rod 60 rear ends is inserted, the surface of the return portion 65 of holding section 63 becomes the state with the inner peripheral surface butt of metallic sheath 10, and the inside of the base portion 62 of securing rod 60 becomes and the crack 13 of metallic sheath 10 and the contacted state of outer peripheral face of the support portion 14 between the square through hole 12.As described above, square through hole 12 and crack 13 form along the state of the axis direction proper alignment of metallic sheath 10, and the length in crack 13 is longer than the length from the front end of the base portion 62 of securing rod 60 to the top of pawl 61.
Thus, bend 66, the first rake 67B and the second rake 67F in the place ahead of the base portion 62 of securing rod 60 are arranged in crack 13, keep pawl 61 from the outstanding state of the outer peripheral face of fitting portion 11.Like this, securing rod 60 is retained as from the place ahead part of its base portion 62 and can swings at above-below direction.That is, the corner part P that securing rod 60 is retained as with support portion 14 is that fulcrum carries out presser motion, and on the other hand, pawl 61 abuts on the inner peripheral surface of metallic sheath 10 by the surface of the return portion 65 of holding section 63, and is maintained on the position of predetermined altitude.
Therefore, when the fitting portion 11 of the connector of above-mentioned formation being inserted, be fitted to when being connected electric contact 40 on the other side's terminal in the other side's connector that is suitable for this connector, the pawl 61 of rubber-like securing rod 60 is temporarily depressed downwards, final connect the time engrave, pawl 61 returns on the desired height position, and the rear end face of pawl 61 only blocks mutually with the fastener of the other side's connector.Its result, the connector of above-mentioned formation can not deviate from from the other side's connector, and therefore, the connection status between two connectors is positively kept, and connector can not take place miss the accident of extracting and connection being interrupted.
And, shown in Fig. 7 B like that, on the part of the insulating body 30 of the inside of the crack 13 formed parts that are positioned at metallic sheath 10, form groove 31, constitute the presser motion that does not hinder securing rod 60.
When the connection between contact two connectors, must make the fastener of pawl 61 disengaging the other side connectors of securing rod 60.For this reason, as shown in Figure 7, form securing rod press section 23 covering on the insulator cap 20 of metallic sheath 10, this securing rod press section 23 has from extend to the shaft-like elasticity of cantilever support of the front end of base portion 62 near the rearward end of the second rake 67F of securing rod 60 (end of the first rake 67B side) along axis direction.The protuberance 24 that near the upper surface of this securing rod press section 23 its base portion inner surface is provided with rearward end with the second rake 67F connects tilts obliquely upward from its base portion, and its free end is projected into the outside of the outer peripheral face of insulator cap 20.The free-ended upper surface of securing rod press section 23 forms smooth, carries out the action that this securing rod press section 23 is pushed easily downwards.And the securing rod press section 23 formed parts of insulator cap 20 become opening 22, with the presser motion of this securing rod press section 23 of obstruction free.
In the above-described configuration, when the free end of securing rod press section 23 is pushed downwards, the protuberance 24 of the base portion inner surface of securing rod press section 23 securing rod 60 downwards (internal direction of metallic sheath 10) push, therefore, the pawl 61 of securing rod 60 is pressed in the metallic sheath 10.Its result, the pawl 61 of securing rod 60 can break away from from the fastener of the other side's connector, and connector shown in Figure 7 is taken out from the other side's connector.
As described above, in the prior art, securing rod 60 carries out needed bending machining by the metal strip to reservation shape and forms.The possibility that the structure that depends on such bending machining exists processing dimension to change with batch difference of material, the problem that exists size to change easily.
When Change Example such as pawl 61 are with respect to the height and position of base portion 62 along with the variation (change) of processing dimension, pawl 61 changes from the projecting height of the outer peripheral face of the fitting portion 11 of metallic sheath 10, therefore, pawl 61 ends state variation with respect to the card of the fastener of the other side's connector.Its result can take place for example to block and end bad defectives such as feel variation when contacting card and end.
Under such situation,, in the prior art,, adjust the height of pawl 61 by angle of bend θ (with reference to Fig. 8 B) though can adjust the height of pawl 61.That is,, adjust the height of pawl 61, therefore, need to transform the bending mould of bend 66 by adjusting the degree of crook of bend 66.
But the transformation of the bending mould of bend 66 is not easy, needs to spend time.And when transforming precision face and mould, there is the problem that is difficult for returning on the original form.The defective that is difficult for carrying out the securing rod Height Adjustment is arranged like this.
