Description

The present invention relates to a contact sleeve for the outer conductor of a coaxial plug connection.

European Patent EP1641086B1 discloses a plug connector operable with a reduced insertion force. In this regard, a plug connector having a radially open ring is described, which ring is radially expanded when the plug connector is inserted.

DE 19913898 C1 discloses a contact sleeve (10, 100) for the outer conductor of a first connector of an HF plug connection (50), the contact sleeve (10, 100) comprising at least one slot 14 in the front region ( 12), the slot is dimensioned such that the front region closes itself when the contact sleeve is connected to the second connector 40, and the front region has an annular design.

In this context, the object of the invention is to provide a plug connection with improved electrical properties.

According to the invention, this object is achieved by a contact sleeve for the outer conductor of a high-frequency plug connection having the features of claim 1 and/or by an HF plug connection having the features of claim 10.

Correspondingly, the present invention provides the following contents.

A contact sleeve having an anterior region with at least one slot for the outer conductor of a first connector of an HF plug connection, said slot being provided when said contact sleeve is connected to a second connector. The region has dimensions such that it closes itself, and the front region has an annular design, the slot forming an angle with the longitudinal axis (42) of the contact sleeve to define the longitudinal axis. The slot includes an angle of between 15° and 60°.

The idea of the invention is that the contact for the outer conductor of the first connector is designed such that the front region of the contact sleeve is as circumferential as possible when plugged in, i.e. it is designed to be substantially free of breaking points. To design the sleeve.

According to the invention, the slot in the front region is designed to close itself when connected to the second connector.

The contact sleeve according to the invention thus guarantees a more uniform distribution of the impedance, when the contact sleeve is in the inserted state, via the substantially circumferential front region.

The angle of the slot with respect to the longitudinal axis of the contact sleeve provides a unique mechanical advantage with respect to tolerance compensation.

It should be understood that the term "front region of the circumference" refers to the co-inserted condition of the contact sleeve.

Advantageous embodiments and inventive steps are self-evident from the further dependent claims and from the description with reference to the drawings.

According to a preferred embodiment of the present invention, the slot in the contact sleeve reduces the insertion force when the first connector is connected to the second connector of the HF plug connection and also provides tolerance compensation. Designed.

Through the slot, the insertion force required for the contact sleeve to be connected to the second connector can be reduced compared to a contact sleeve having a front region without a slot.

It should be noted that the contact sleeve according to the invention is such that the oversized or undersized dimensions of the front side region, when inserted together, are due to the opposite sides of the slot displacing relative to each other and to the remainder of the opposite sides of the slot. Tolerance compensation is provided to the extent that it is compensated for by the gap.

Those skilled in the art use the term "self-closing" to mean that when the contact sleeve is connected to the second connector, the opposite sides of the slot move toward each other and desirably contact each other. You will understand. However, one of ordinary skill in the art will recognize that the remaining small gaps between opposing sides of the slot may not be completely closed due to possible manufacturing tolerances.

According to a further preferred embodiment, the contact sleeve comprises an elastic region having at least one recess configured to provide the deformability of the elastic region and to further reduce the insertion force.

The elastic region according to the invention further increases the conformability and deformability of the contact sleeve via the recess of the elastic region, which ensures that the front region is displaced with respect to the elastic region. This is particularly advantageous in the case of small plug connections with a low insertion force.

According to a further preferred embodiment, the longitudinal axis and the slot form an angle of between 30° and 50°, in particular an angle of approximately 45°. Correspondingly, when the slots form an angle of 45° with respect to the longitudinal axis, the risk of tilting of the opposite sides of the slots and the opposite sides of the slots are particularly easily related to each other. The ability to displace with respect to one another ensures maximum tolerance compensation of the diameter.

According to a further preferred embodiment, the elastic region has a protrusion configured to provide electrical contact with the second connector, in particular the protrusion is located radially adjacent to the recess. To be done. Thus, the two outer conductors to be connected of the first connector and the second connector can be contacted in a particularly simple manner. It should be noted that this type of contact proves to be particularly fail-safe in the event of vibration or shock.

According to a further preferred embodiment, the contact sleeve has at least two recesses, in particular at least four recesses, and more particularly at least six recesses. Those skilled in the art will appreciate that both the number of recesses and their geometrical dimensions are defined depending on the dimensions of the contact sleeve.

According to a further preferred embodiment, the front region of the contact sleeve tapers towards the front. This further reduces the insertion force required to connect the contact sleeve to the second connector.

An HF plug connection with a first connector and a second connector is particularly advantageous, the first connector having a contact sleeve according to the invention and the contact sleeve being designed as an outer conductor.

According to a preferred embodiment of the HF plug connection according to the invention, the first connector is designed as a plug and the second connector is designed as a socket. However, those skilled in the art will understand that non-male/female connectors are also within the scope of protection of this patent application. It will be appreciated by those skilled in the art that the contact sleeve according to the present invention may form part of a socket.

According to a preferred embodiment of the HF plug connection according to the invention, the second connector comprises latching means suitable for latching on the projection. For example, the latching means can be designed as a recess corresponding to the protrusion. Therefore, the reliability of the contact can be further improved.

Where appropriate, the embodiments and improvements described above can be combined with one another in any form. Further possible examples, improvements and embodiments of the invention also include combinations of features of the invention not explicitly mentioned, for the exemplary embodiments these combinations have been mentioned above or below. To do. In particular, the person skilled in the art will add individual aspects as improvements or supplements to each basic form of the invention.
