## Abstract

A coaxial connection system including a first system element forming a plug and a second system element forming a socket, each including a central contact and a peripheral body. The connection system includes a locking cap/nut, mounted free at least in translation around the plug or the jack, between an unlocking position and a locking position, and two annular sealing members of elastomeric material resistant to corrosion, one being arranged around the plug and the other around the jack and each being distant from the connection interface between the plug and the jack. The locking cap/nut is at least on its external surface in a corrosion-resistant material. The arrangement of the locking cap/nut and of the two annular sealing members is such that the locking cap/nut achieves in its locking position a radial compression to the inside the two annular sealing members defining a waterproof cavity.

## Claims

### Claim 1

A coaxial connection system, intended to be used in an outdoor environment, comprising:
a first system element forming a plug and a second system element forming a socket, the plug and the socket each comprising:
a central contact,
a peripheral body, arranged on the periphery of the central contact,
a locking cap or nut, mounted free at least in translation around the plug or the jack, between an unlocking position, in which the plug and jack are not locked and a locking position, in which it mechanically locks the plug and the jack in their mutual connecting configuration;
two annular sealing members of elastomeric material resistant to corrosion, one being arranged around the peripheral body of the plug and the other around the peripheral body of the jack, each being distant from the connection interface between the plug and the jack;
wherein said locking cap/nut is at least on its external surface in a corrosion-resistant material; and
wherein the arrangement of said locking cap/nut and of said two annular sealing members is such that the locking cap/nut achieves in its locking position a radial compression to the inside the two annular sealing members defining with them a waterproof cavity.

### Claim 2 (depends on 1)

The coaxial connection system according to claim 1, wherein the sealing members are elastic O-ring seals.

### Claim 3 (depends on 1)

The coaxial connection system according to claim 1, wherein each sealing member is arranged in a groove of the periphery of the peripheral body.

### Claim 4 (depends on 3)

The coaxial connection system according to claim 3, wherein the inner diameter of each of the sealing members is smaller than the bottom diameter of the groove while its outer diameter is greater than the inner diameter of the locking cap.

### Claim 5 (depends on 1)

The coaxial connection system according to claim 1, wherein the locking cap ensures the locking by an internal portion being screwed onto a peripheral portion of the peripheral of the jack.

### Claim 6 (depends on 1)

The coaxial connection system according to claim 1, wherein the locking cap ensures the locking by clipping means clipped onto the peripheral body of the jack.

### Claim 7 (depends on 1)

The coaxial connection system according to claim 1, wherein the locking cap has a peripheral chamfer at least at one of its free ends which diameter is larger than the outer diameter of the annular sealing members.

### Claim 8 (depends on 1)

The coaxial connection system according to claim 1, wherein the locking cap is made of a very low or null electrical conductivity material or is coated with a coated with galvanic anti-corrosion coating.

### Claim 9 (depends on 8)

The coaxial connection system according to claim 8, wherein the locking cap is made in an amorphous metal.
