Abstract

A cable end plug for plugging on coaxial cables (1) has a plug sleeve (15) consisting of insulating material for accommodating a stepped coaxial cable (1). A contact sleeve (17) is provided on the plug sleeve (15), for an electrical connection between the outer conductor (5) and an associated plug connection (7). However, the contact sleeve is expensive to produce, especially if it is manufactured from beryllium. In addition, the functional reliability can be further improved. A correspondingly improved cable end plug has inner contact laminates (21''), which are aligned on the outer conductor towards its end, and outer contact laminates (21'), which are aligned in the opposite direction, on the outer circumference of the plug sleeve (15). The cable end plug is particularly suitable for coaxial cables. <IMAGE>

Description

The invention relates to a cable end plug for plugging on on coaxial cable according to the preamble of claim 1.

A generic cable end plug is, for example DE-33 26 128 A1 become known. The cable end plug consists of an electrically insulating connector sleeve, about the different diameters of a plug connection and the coaxial cable to be inserted can. With the help of a resilient contact ring or The contact sleeve becomes the outer conductor of a remote coaxial electrically connected to the plug connector.  

The contact ring has a large number of resilient contact clips due to radial breakthroughs of the connector sleeve protrude for contacting the outer conductor. The inner conductor of the coaxial cable is through a opposite of the Einstecköff opposite opening in the cable end connector passable.

The use of the contact ring mentioned with a before whose and rear sleeve section that on is in contact with the outer conductor and the in-between build to the outside running spring clips, that here several contact points are necessary that lead to impairment electrical contact and damping which can carry transmission signals.

This is especially true when using a standard contact sleeve, each starting alternating outward and inward protruding bulbous Has contact sections over which the contacting once to the outer conductor and once to the conductive inner surface of a Plug connection should take place. Here are up to four or six contact points and auxiliary contacts are necessary, where part of a con clock lamella, for example, as a power loss generating antenna can act.

In the prior art cited at the beginning, how mentioned, the peripheral bands of the contact sleeve flat on the outside conductor of the coaxial cable and can essentially only exert radial forces on the outer conductor.  

As a result, the coaxial cable is relatively light the receptacle can be pulled out, causing problems when sealing the outer conductor of the coaxial cable against run over the housing passage point of the inner conductor can. The contact leaf springs must have high radial forces apply and consist of high quality material, for example wise from a berillium spring alloy. For rolled spring Sleeves of the proposed type are relatively much of this cost playful material required, especially if you cover, that the waste material resulting from the load is not can be used again.

The con tact leaf springs as single leaf springs to train, is from DE 33 41 356 A1 known. Such leaf springs can be largely cut free from tape material, for example also from a berillium Make alloy. The assembly effort is quite not insignificant, the problem of not being desired here too damping due to not always optimal contact ratio se can occur at least in unfavorable cases.

The object of the present invention is therefore based on based on the prior art mentioned at the outset To create cable end plugs for a coaxial cable, the pro is easy to produce in terms of production technology and that above all, a high level of functional reliability and a clearly reproducible con clocks creates.  

This object is inventively according to the in Drawing part of claim 1 specified features solved.

Advantageous embodiments of the invention are shown in specified in the subclaims.

The present invention makes it extremely compact Contact sleeve created, the production technically simple is adjustable, and with little waste material. This is particularly important if the one to be manufactured Contact sleeve made of a berillium alloy should. In addition, there are clearly reproducible Contact relationships. According to the invention only exist two contact transitions, namely once from the outer conductor to Contact sleeve and further from the contact sleeve to the plug connection, for example a coaxial connection device.

Since the individual contact tongues with sufficient contact pressure at the respective contact point NEN, no unwanted damping can occur. Above all, the contact blades with such a high Contact pressure should be provided that also an unintended Detach the cable end plug from the coaxial cable or else of the coaxial connector relative to the plug-in connection be avoided.

In a particularly preferred embodiment, the Contact sleeve made of a metal sheet by punching and deep drawing. This method is particularly suitable when using berillium alloy sheets.  

The contact tongues are a means section in the manner of a radial perforated disc connected. This middle section is integrated in the from insulated material manufactured plug sleeve arranged, the entire cable end connector consists of two parts can of the thus formed central section in the merged integrated state.

Embodiments of the invention are below based on drawings explained. It shows in detail nen

Figure 1 is a schematic axial longitudinal section through a cable end connector.

Fig. 2 is a radial side view of a ver in Fig 1 contact sleeve;

Fig. 3 is an axial view of the contact sleeves according to Fig. 2;

Fig. 4 a partial modification of the wire end connector with FIG. 1.

In Fig. 1 in longitudinal section of a coaxial cable 1 having an inner conductor 3, an outer conductor 5 and an insulation not designated nä forth is shown, which connection in a plug 7 of a terminal device 9 is inserted. The final anchoring and insulation of the coaxial cable 1 at the plug connection 7 takes place via a shrunk-on shrink tube 11 , via which the tensile forces introduced via the coaxial cable can also be absorbed.

To this extent, reference is made to known general attachments of the axial cable 1 Ko.

In the exemplary embodiment shown, the coaxial cable 1 is not plugged directly into the plug connection 7 , but rather a cable end plug 13 is first placed on the remote coaxial cable and then both are plugged together into the plug connection 7 .

The cable end plug 13 is made of insulating material, for example plastic material.

In the schematic diagram of Fig. 1, the cable end connector 13 is separated in the axial direction in two connector sleeve parts 15 ', 15'' . Arranged between them is a contact sleeve 17 , as shown as an individual part in FIGS. 2 and 3.

The contact sleeve 17 comprises a central section in the manner of a radially arranged annular disk 19 . On both sides of this central washer 19 , individual contact tongues 21 are arranged, the outer contact tongues 21 ' for contacting the contact sleeve 17 with the conductive inner wall of the plug connection 7 to the insertion opening 23 in the plug connection 7 and the inner contact tongues 21'' in opposite set Direction towards the end of the plug connection 7 extends. The outer contact tongues are at least slightly biased outwards, namely in the unloaded state over the cross section of the plug connection ses 7 , and the inner contact tongues 21 '' biased inward beyond the outer circumference of the outer conductor 5 .

The contact sleeve shown in FIGS. 2 and 3 can be easily punched out of a metal sheet and then deep drawn. This method is also particularly suitable when using berillium or berillium alloy sheets.

Furthermore, in the embodiment shown, three further recesses 25 are introduced in the middle section, ie in the annular disk 19 , via which the two plug sleeve parts 15 ', 15''of the cable plug 13 can be connected to one another. For this purpose, at least one of the two connector sleeve parts 15 ', 15''can be provided with corresponding jumps 27 which engage in the assembled state through the recess 25 . Both plastic be standing connector sleeve parts 15 ', 15'' can be welded in this assembled condition on the projections 27 to the adjacent adjacent connector sleeve part, so that an indissoluble solid unit is given.

The contact tongues 21 can each be slightly bent outwards or inwards so that high contact forces are generated.
