Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector used for interconnecting coaxial capes μ.

The object of the present invention is to provide a connector capable of interconnecting the coaxial cables without using tools such as a bench.

The drawings showing the embodiments of the present application will be described below.

1 indicates a main body of the connector. In this main body 1, a holder 2 is composed of two holder elements 2a and 2b, and the projections 3a and 3b of one are fitted into the four parts 4a and 4b of the other to connect them. That's how it is. Each of the above-mentioned elements is formed of a synthetic resin material such as AB8 resin, but it may also be formed of a metal material, and the above-mentioned elements may be joined by adhesive means. In the above-mentioned holder 2, 5 indicates a holding portion, and 6 indicates a storage space.

Reference numeral 7 denotes a fitting recess, which is formed between the projecting pieces 8, 8. 9
indicates the knob, and it is advisable to form a large number of concave and convex portions here to secure the bevel. 10 indicates a threaded portion.

Next, 11 indicates an external conductor connector. This fitting consists of two elements 11a, 11&. These elements are formed by press-molding metal plates with good conductivity, such as brass plates or iron plates. In the connecting tool 11, [ is a retaining portion where an insulating tube, which will be described later, is retained. 13
14 represents a fitting hole, 14 represents a fitting piece, and 14 represents a tapered attachment portion.

Next, 17 is an insulating tube, and two elements 17 and 17 each made of an insulating material such as a synthetic resin material (for example, polyethylene)
, 17 &. In each element, numeral 19 indicates a fitting protrusion, numeral 19 indicates an insertion hole for the center conductor, and numeral 19 indicates a fitting recess formed in the shape of a groove.

Next, η is a center conductor connector, which is punched out of a metal plate material with high conductivity and elasticity, such as phosphor bronze, by pressing means, as shown in Figure 7, and then folded into two. It is constructed by folding. This connecting device η is composed of a connecting portion O, 23 and a conductive portion that connects both the connecting portions to each other. At the connection n, part.

The part is a pair of clamping pieces, and the tip part has a guide part in the shape of an opening,
26 and wall pieces 27 are provided.

Next is a fixture, which includes a threaded part 31 that is screwed into the threaded part 1O, an annular pressing part formed on the inner circumferential surface, and a number of screws for fastening. The knob blades, etc. are formed with unevenness. Further, this fixture is made of a highly elastic synthetic resin material such as ABS resin.

Next, the procedure for assembling the connector main body 1 will be explained. First, both elements 17 &
17. Cover the connection section row from the 23 side.

In this case, the edges 24a, 24a of the conducting part barb are respectively connected to the element 17.
It is made to slide into the groove-shaped fitting recess formed in the part a, and the fitting parts (R) of both elements 17a, 17& are made to fit together with each other.

Next, both elements 1 of the external conductor connector 11 are connected to the insulating cylinder 17.
Cover with 1 a, 11 &. In this case, as shown in FIG. 8, the fitting protrusion fits into the fitting hole 13, and the fitting pieces 14, 1 of both elements 11a, 11a, respectively.
4 to polymerize with each other.

Next, place the assembly assembled as described above on one of the holder elements 2.
a as shown in FIG.

In this case, the mutually overlapping fitting pieces 14 are positioned within the fitting part 7. Next, the other holder element 2b is joined to the above-mentioned holder element 2a. In this case, the projecting pieces 3a, 3b
so that they fit into the recesses 4a and 4b, respectively. The connector main body 1 is completed by the above-mentioned operations.

In the above-mentioned completed connector main body, the fitting piece 14 fits into the fitting part 7, so movement (axial movement and rotational movement) of the external conductor connector U with respect to the holder 2 is prevented. In addition, since the fitting protrusion rib is fitted into the fitting hole opening, the insulating tube 17 is connected to the external conductor connector 11.
The fixation (fixation in the axial direction and rotational direction) of the center conductor connector ρ is well achieved, and since the edge 24a is fitted into the fitting recess, the fixation of the center conductor connector ρ to the insulating tube 17 ( The axial force (fixation in the axial direction and rotational direction) is also ensured.

Next, when connecting a coaxial cable (for example, 502V) 35 to the connector main body, the end of the coaxial cable section is first processed in a well-known manner to expose the outer conductor part and the center conductor a. Next, the coaxial cape A/35
Insert into the insertion hole of the fixture. Next, the insulator and the center conductor a at the terminal are inserted into the attached part of the outer conductor connector 11, and the center conductor a is passed through the insertion hole 19 of the insulating tube 17 to the pair of clamps at the connection part n. Insert between the pieces. This achieves an electrical as well as a mechanical connection of the center conductor to the multiple connection rows. At this time, the external conductor garden will be attached to the outer surface of the attached city. In the above case, the work of inserting the center conductor W between the clamping pieces 6 can be carried out very smoothly since the guiding part and the wall piece are provided at the tips of the clamping pieces.

(4) After inserting as above, insert the screw part with the fixing tool into the screw part 1.
0 and tighten the fixture (materials) to the main body 1.

Then, the outer conductor is pressed against the attached part by the outer conductor opening suppressing part, and a good electrical and mechanical connection state between the outer conductor hole and the outer conductor connector 11 is achieved. The above-mentioned tightening is preferably performed by pinching the knob 9 with the fingers of one hand and pinching the knob 9 with the fingers of the other hand.

By performing the above operations on two coaxial cables to be connected using a connector, these coaxial cables can be electrically and mechanically connected to each other.

In the above connection state, the inner diameter of the insertion hole in the fixing device is formed to a small diameter with a slight margin compared to the outer diameter of the coaxial cable, so the coaxial cape/L /35 movement (lateral movement) is restricted, and as a result, an accident in which the external conductor connected as described above is bent and cut at the part marked (a) is prevented.

Next, when connecting a small-diameter coaxial cape /I/ (for example, 802 V), an auxiliary ring made of synthetic resin such as AB8 resin is used as shown in FIGS. 10 and 11. That is, the insertion part 41 of the auxiliary ring cutter is inserted into the insertion hole between the internal fixing tools, so that the collar 42 of the auxiliary ring cutter comes into contact with the end of the fixing tool. In this state, a thin coaxial cape A/35' is attached inside the auxiliary ring.
Insert. In this case, the outer diameter of the insertion portion 41 is
By forming the auxiliary ring in advance to a size that presses against the protrusion formed inside the insertion hole bar, it is possible to prevent the auxiliary ring from being removed from the fixture. Also, by forming the inner diameter of the auxiliary ring ω to be slightly larger than the outer diameter of the small diameter coaxial cape 7', the small diameter coaxial cable /L/3 is formed similarly to the large diameter coaxial cable.
5, which helps prevent cutting of the outer conductor in its coaxial cape μ.

Next, Fig. 12 shows a different embodiment of the fixing device, in which the external groove (7) of the coaxial cable is attached to the attachment part using a planar pressing part instead of the thin linear (annular) pressing part as described above. This shows an example in which the signal can be suppressed to 15e.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

As described above, the present invention has the advantage that the terminals of two coaxial cables can be connected to each other.
