Definitions
- the invention relates to a coaxial connector according to the generic term of Claim 1.
- a coaxial connector is known from US-A-5 417 588.
- the two-part insulating part has the shape of two hollow cylinders.
- a coaxial connector is known from EP 0 675 566 A2, in which to support and center the inner conductor in an outer conductor housing two consecutively arranged Insulating body provided and between a diameter step on the inner wall of the outer conductor housing and another part, namely an outer conductor connection piece are fixed.
- the inner conductor designed as a plug has a pin-shaped plug area and one in the outer diameter multi-graded socket-shaped connector area to insert the inner conductor of a coaxial cable.
- the course of the socket-shaped plug area is on the outer circumference a circumferential groove of the inner conductor as a gradation in diameter provided with a peripheral side flank.
- the Inner conductor is inserted into both insulating material bodies is through the second insulating body in the axial direction held in the outer conductor housing.
- the second is Insulating body with a relatively thin, with a passage opening provided transverse wall with radially resilient locking elements trained when inserting the inner conductor in the second insulating body in the gradation on the outer circumference of the inner conductor.
- the invention is based, a coaxial connector and simple fixation of the task Inner conductor in the for its support and centering in provided an outer conductor housing Insulation and a simple fixation of this insulation in the outer conductor housing specify.
- This task is the one mentioned in a coaxial connector Art solved according to the invention in that the Insulation insert that can be inserted into the outer conductor housing in one piece and at a front and a rear end each with at least two radially resilient clamping elements is formed that the largest inside clearance of the rear End of the insulating part at least equal to the inside width of the outer conductor housing is selected so that the insulating part through the resilient clamping elements at its rear end is fixed in the outer conductor housing by means of a clamp fit the inner conductor that can be pushed into the insulating part as far as it will go between a free, rear connection section and a free, front plug-in section in its clear outer width to the inside width of the front end of the insulating part has coordinated middle section and in this Middle section through the resilient clamping elements of the front End of the insulating part by means of a clamp fit in the insulating part is fixed.
- a coaxial connector In such a coaxial connector is the one-piece insulating part for supporting and centering the inner conductor in the outer conductor housing of the coaxial connector at both ends formed with resilient clamping elements.
- the serve Clamping elements at one end of the insulating part of the fixation of the insulating part itself in the outer conductor housing Clamp fit while the clamping elements at the other end of the insulating part fixing the inner conductor in the insulating part effect and also by means of a press fit.
- the coaxial connector according to Figure 1 has an essentially cylindrical outer conductor housing 2, which is at right angles to its longitudinal axis protruding connector 3 for a not Has coaxial cable shown in detail on the rear End is open and has an internal thread 4 and at its front End of a longitudinally slotted and therefore with spring slats 5 trained outer conductor socket 6 and a union nut 7 to connect z. B. with a mating connector wearing.
- inner conductor 8 shown in the outer conductor housing 2 a one-piece insulating part 9 is provided. Training this insulating part 9 and the inner conductor 8 is in the following with reference to Figures 2 and 3 and Figure 4 described in more detail. According to FIG.
- the inner conductor 8 is on its front freely protruding from the insulating part 9 in FIG Plug-in section as a cylindrical plug pin 10 with a conical, rounded tip formed at the end.
- the rear End of the inner conductor 8, which also in the figure as free, not carried by the insulating part 9 end recognizable is the cylindrical connecting portion 11th of the inner conductor and is used to connect a bare or insulated electrical conductor, e.g. B. for connecting the inner conductor one over the connector 3 in the coaxial connector introduced coaxial cable.
- This is the connection section 11 of the inner conductor 8 with a clamping slot 12 formed, which for the connection of an insulated in particular electrical conductor of the insulation of the electrical Conductor penetrating cutting edges can be limited.
- the inner conductor 8 has a cylindrical central section 13, which - as can be clearly seen in FIG. 1 - forms the area in which the inner conductor 8 of the Insulating part 9 is worn.
- the inner conductor 8 with one provided here ring-shaped stop 14, the Outside diameter is larger than the outside diameter of the Middle section 13 so that the stop 14 the insertion of the Inner conductor 8 limited in the insulating part 9 when it is on one Stop 29 on the inner wall of the insulating part, for. B. on a diameter gradation.
- the one-piece, essentially hollow cylindrical insulating part 9 in Figures 2 and 3 has a relative diameter small middle section 15, on which on one side over a cone-shaped section 16 to the rear end 17 and on the other side, a stop designed in a ring shape here 18 and connect the front end 19, which alone the Inner conductor 8 picks up and carries.
- the insulating part 9 each has at least two radially resilient Clamping elements 20, 21 or 22, 23, which by two slots 24, 25 and 26, 27 are formed, respectively Longitudinal direction of the insulating part 9 and extend in the case of the rear end 17 of the insulating part from the free end face of the clamping elements 20, 21 over the conical section 16 to the middle section 15 and in the case of the front End 19 extend over its entire length.
- the biggest Outside diameter of the rear end 17 of the insulating part in Area of the approximately semi-cylindrical clamping elements 20, 21 is at least equal to the inner diameter of the outer conductor housing 2 in the area after its internal thread 4, so that Insulating part 9 inserted into the outer conductor housing 2 Condition by the resilient clamping elements 20, 21 on his fixed rear end by means of a clamp seat in the outer conductor housing is.
- the stop 18 of the insulating part 9 acts as a slide-in limitation by attaching it to a diameter step 28 abuts the inner wall of the outer conductor housing 2.
- the front end 19th of the insulating part 9 as well as the rear end 17 of the insulating part cross-sectionally cylindrical in the press fit area is, that is the cross-sectional shape of the front and of the rear end 19 or 17 of the insulating part 9 is in each case the cross-sectional shape of the inner conductor 8 or the outer conductor housing 2 adapted in the respective area.
- the one Part consists of insulating material and is a pressure piece 30, which is formed when tightening the screw 31 other part an electrical conductor in the clamping slot 12 of the inner conductor 8 presses.
