Refer to shown in Fig. 2, Fig. 4, Fig. 5 and Fig. 6, described center conductor 20, by metallic plate processing and fabricating, comprises the connecting portion 24 for connecting material strip that the base portion 21 of tabular, the irregular ring-like contact portion 22 extended to form from the described longitudinal side of base portion 21, the pressure contact portion 23 extended to form obliquely from the longitudinal opposite side of described base portion 21 and the minimum one end in described base portion 21 transverse ends portion 27 extend to form downwards.The inner surface punching in described irregular ring-like contact portion 22 is provided with convex closure 26 to contact the center conductor (not shown) of the plate terminal adapter of docking.Described base portion 21 covers described ring-like contact portion 22 completely, prevents dust from being entered in described contact site 22 by described base portion 21 side and affecting performance in electrical contact.Described connecting portion 24 has one at least, extend in parallel formation again after either end in the transverse ends of described base portion 21 extends slightly toward upper bending, the bottom surface of described connecting portion 24 between the end face and bottom surface of described base portion 21, i.e. the horizontal level of a little higher than described base portion 21 of the horizontal level of described connecting portion 24.Described center conductor 20 is when punch forming, and described connecting portion 24 is connected with metal material belt (not shown).
Refer to Fig. 2, Fig. 3, Fig. 5, and shown in Fig. 6, the center conductor 20 that described punching press is good carries out in-mould injection shape all-in-one-piece insulating body 30 subsequently, described insulating body 30 comprises the main part 31 of tubular, to be formed in the middle of described main part 31 and the ring-like contact portion 22 of accommodating described center conductor 20 in interior centre bore 32, from described main part 31 top, both lateral sides extends to form Access Division 33, be formed at the crimping isolation part 35 of the pressure contact portion 23 of the corresponding described center conductor 20 in longitudinal one end, described main part 31 top, and be formed at cable 40 positioning part 34 of the longitudinal other end of described main part 31.The base portion 21 of described center conductor 20 covers the centre bore 32 of described insulating body 30, the transverse ends portion 27 of described center conductor 20 is shaped in the upper end-face edge of the cylindrical body part 31 of described insulating body 30, and the connecting portion 24 of described center conductor 20 is shaped in the Access Division 33 of described insulating body 30.After described center conductor 20 is one-body molded with described insulating body 30, described connecting portion 24 is still connected with material strip, and certainly best execution mode is described connecting portion 24 is two, extends to form respectively from base portion 21 transverse ends 27 of described center conductor 20.
Please refer to shown in Fig. 1 to Fig. 6, described external conductor 10 adopts sheet metal to process, and comprises and is roughly rolled into cylindrical shape and is formed with chimeric cylindrical portion 11, the maintenance wrist 13 extended to form by above-mentioned gap two side position of gap (non-label) at a position of circumferencial direction and in diametric(al), is positioned at the side contrary with described gap and erects by the upper end of described chimeric cylindrical portion 11 cap 12 arranged.
The outer peripheral face lower end of described cylindrical portion 11 plays the circumferential locking groove 111 of lock function when being formed chimeric with the external conductor of butt connector.The top of described cylindrical portion 11 is provided with the draw-in groove 112 coordinated with the Access Division 33 of described insulating body 30, and described insulating body 30 is carried in described draw-in groove 112 by described Access Division 33 clamping.Described cap 12 is connected to above described cylindrical portion 11 to lower cover after assembling completes.Described cap 12 comprises the protection wing 121 also extended to form from the bending of described cap 12 both lateral sides, the surrounding portion 123 extended to form from described maintenance wrist 13 side of vicinity, described cap 12 longitudinal one end, grasping part 124 downwards.When described cap 12 lid is connected in described cylindrical portion 11, the two protection wings 121 of described cap 11 are positioned at outside the Access Division 33 of described insulating body 30, and connecting portion 24 place that the described protection wing 121 is positioned at the center conductor 20 of described Access Division 33 is provided with breach 122.Because described connecting portion 24 connects described center conductor 20, and the described protection wing 121 is a part for described external conductor 10, when described cap 12 is covered in described cylindrical portion 11, the protection wing 121 of described cap 12 both lateral sides very likely contacts the connecting portion 24 being exposed to the center conductor 20 outside described Access Division 33 that the draw-in groove 112 along described cylindrical portion 11 upper end extends, and due to this product size very little, diameter is only 1.64mm, highly be only 0.7mm, and the excision of metal material belt had both likely produced burr at connecting portion 24 edge of described center conductor 20, so, the design of the breach 122 of the described protection wing 121 can ensure described center conductor 20 not with the short circuit of described external conductor 10.
Described cap 12 middle inside is provided with the interior protuberance 125 of the crimping isolation part 35 abutting described insulating body 30 to strengthen the retain strength to the SMIS 41 of cable 40.When described cap 12 is covered in described cylindrical portion 11, described surrounding portion 123 coordinates the maintenance wrist 13 of described cylindrical portion 11 to contact and the braid 42 of cable 40 described in fixing, and described grasping part 124 withholds the external insulation layer 43 of described cable.
The described center conductor 20 be shaped in described insulating body 30 is assemblied in the cylindrical portion 11 of described external conductor 10 by the material strip be connected on described connecting portion 24 in the mode of automatically assembling, and subsequently, cuts off the material strip that described connecting portion 24 connects; Then, the cable 40 stripped is placed in tram, again described cap 12 downward bending is covered in described cylindrical portion 11, rivet described surrounding portion 123, grasping part 124, now, on the protection wing 121 of described cap 12 both lateral sides breach 122 make described in the connecting portion 24 be exposed to outside described Access Division 33 expose the external world; Finally, the material-strap structure excising described external conductor 10 completes assembling.
Compared to prior art, together with the center conductor 20 of line end radio frequency connector of the present invention is shaped in described insulating body 30, avoid prior art because of product size too small, the problem that automatic assembling center conductor 20 difficulty is excessive; Meanwhile, the protection wing 121 of described external conductor 10 both lateral sides is provided with breach 122, and described breach 122 makes the connecting portion 24 of described connection material strip be exposed to the external world, thus avoids contacting described external conductor 10 to cause the possibility of short circuit.
