Description

The present invention relates to a coaxial connector, in particular a coaxial connector used for coaxial cords. Coaxial cords are used for example to connect together radiofrequency modules fixed in a bay. It is known to use connectors for making such leads as shown in FIG. 1. The connector shown in FIG. 1, generally designated 1, has a body generally designated 2 and extending along a first axis. longitudinal X, this X axis here being rectilinear. The connector 1 also comprises an insulator 3, for example of tubular shape, which is received inside the body 2, a central contact 4 mounted in the body 2 with interposition of the insulator 3, and a seal 5. In the example shown, the body 2 is bent, having a shaft 6 extending along a second axis Y not parallel to the first axis X, the Y axis being for example perpendicular to the axis X. The body 2 is in the example of Figure 1 made by machining or molding.

The connector 1 further comprises a plug, generally designated 5, which is for example made by machining. The plug 5 of the connector according to FIG. 1 extends only over part of the length of the body 2, from a longitudinal front end 8 of the body 2, said part of the body being intended to come into contact with the complementary type connector and being called thereafter "connection interface". In what follows, the term "front longitudinal end of the body" means the longitudinal end of the body 2 facing a complementary type connector during a connection operation. The term "longitudinal rear end of the body" means the longitudinal end along the X axis opposite the longitudinal end of the connector. To disconnect the connector from a complementary type connector, a user can grasp the outer surface of the plug 5 and pull the connector back manually or using a specific tool. The plug 5 of the connector according to Figure 1 is provided only to provide connector gripping functions during connection operations or protection functions of the connection interface of the connector. The cap 5 of the connector according to Figure 1 does not include protecting the body of the connector, this protection being desirable to prevent the body is damaged by scratches, knocks or other such damage to the body may affect the electrical continuity provided by the latter between the complementary type connector, for example mounted on a bay, and the braid of a coaxial cable on which the connector is mounted. Damage to the body can shorten the life of the connector. There is a need for a coaxial connector that is more robust than existing connectors but a simplicity and size similar to those of these connectors. The object of the invention is to meet this need and it achieves this, according to one of its aspects, thanks to a coaxial connector comprising: a body extending along a first longitudinal axis and defining a mass contact, the body having a portion intended to come into contact with a complementary type connector during a connection operation, said portion defining a connection interface, - a central contact disposed in a housing formed in the body, an insulator interposed between the contact central and the ground contact and a plug mounted on the body, characterized in that the plug is disposed on all or part of the periphery of at least a portion of the body other than the connection interface.

The portion of the body around the periphery of which the cap is disposed may extend over at least 50% of the length of the body, said length being measured along the first longitudinal axis of the body, in particular at least 75%, in particular 90% , even over the entire length of the body. Due to the arrangement of the cap relative to the body, the stopper axially overlaps the body over all or part of its length, which makes it possible to protect all or part of the body with respect to external aggressions such as scratches, blows or other, thus maintaining the electrical continuity provided by the body and thus increasing the life of the connector body. In addition, because of its position relative to the body, the plug can participate in the coaxial line and reduce the risk of radiofrequency leakage and impedance breakage. The cap is for example arranged around all or part of the connection interface of the body and around said portion other than the connection interface.

The plug may be made of plastic material, the latter being for example an injection-molded plastic material selected from the group comprising PAA (polyaryl-amide), PAI (polyamide-imide), PPS (polyphenylene sulfide) and PBT (polybutylene terephthalate).

The injected plastics material may include a dye, which can be used to add a "coding" type of functionality to the cap, allowing the connector to be particularized with a particular color and to quickly identify which connector of the complementary type it must be connected to. . The plastics material may comprise fibers, for example glass, carbon or metal fibers. The insulation can be a separate part of the body, being configured to be inserted into the body. The body can be made by machining or, alternatively, by MIM type technologies (injection of metal powders). Alternatively, the body may be made by molding plastic material (s).

The insulation can be made in one piece with the body. According to this variant, the body may comprise at least one metallized surface defining the mass contact. The metallized surface may be an outer surface of the body. The body may for example be metallized over its entire surface except for a zone of the housing wall formed in the body. The plug can then be disposed at least around all or part of the body portion. whose housing wall corresponds to said non-metallized zone. Such an arrangement of the plug makes it possible to protect the outer surface of the body at the level of said non-metallized zone, that is to say to protect the ground contact directly participating in the coaxial line. The central contact can be a separate part of the body, being configured to be placed in the body, or, when the body is made of plastics, to be formed by a metallized wall of the housing formed inside. from the body. The cap may comprise a rear portion comprising at least one relief defining a gripping portion. This is for example at least one rib extending along the first axis on the outer surface of the cap and whose height relative to the cap increases as one approaches the longitudinal end. back of the body.

The cap comprises for example two diametrically opposed ribs and formed on the cap, these ribs may have a regular surface or not, said surface having for example streaks. With such a connector, the gripping portion can be moved to the rear of the connector, making it possible to perform the connection and / or disconnection operations from the rear of the connector. Alternatively, the connector has a gripping portion extending beyond the rear longitudinal end of the plug. This gripping portion extends for example along the first longitudinal axis of the body. The presence on the back of the connector of the gripping part can make it possible to densify the number of connections on the same panel, reducing the transverse dimensions occupied by the connector. The gripping portion can be made in one piece, in particular by molding material with the cap. Alternatively, the gripping portion is a separate part of the cap, being for example made by overmolding on the latter or being reported on the latter. The gripping portion is for example a tongue that can be rigid or made of a flexible material, for example PU (polyurethane), TPE-U (thermoplastic elastomer-urethane or TPU (thermoplastic polyurethane) .The plastic material in which is realized the plug is advantageously insulating so as to secure the gripping by a user of the connector and this material may be chosen to significantly improve the resistance of the salt spray plug The plug advantageously comprises an inner housing of which at least one portion has a section The polygonal cross-section of the housing defines, for example, a star, such a polygonal shape, in particular a star-shaped shape, of the housing can not only ensure that the body is guided in a polygonal cross-section, the body being received inside the housing. the cap, but also to provide a protection of the body when the cap is soumi This configuration can allow the plug to take up torsional forces exerted on the connector, these forces not being transmitted to the body. When the connection interface of the body comprises means configured to perform centering and / or support functions, including locking, when connecting the connector to a complementary type of connector, the plug can be used to control the deformation of these means during a torsion moment applied to the connector. Such means configured to perform centering and / or support functions are for example described in the application filed by the Applicant in France under the number 09 55817. The connector is advantageously bent. The rear end of the body can then be closed by a cover and the portion of the body around which the cap is disposed can extend from the connection interface to the cover. In a variant, the portion of the body on the periphery of which the stopper is arranged can extend from the connection plane to the cover. The term "connection plane" designates the support zone between the connector and the complementary type connector which closes the coaxial line and ensure the electrical continuity of the coaxial line. According to another of its aspects, the invention also relates to a coaxial connector comprising: a central contact, a body extending along a first longitudinal axis and inside which a housing is formed, the outer surface of the body comprising at least one metallized portion defining a mass contact and, at least one region of the wall defining the housing being non-metallized, so as to form an insulator interposed between the central contact and the ground contact, and - a plug disposed around all or part of the body, at least up to said non-metallized area.

Other characteristics and advantageous properties of the invention will be understood in the following reading of non-limiting examples thereof and on examining the appended drawing in which FIG. 1 represents an example of a connector already known, FIG. 2 diagrammatically represents a connector according to a first exemplary embodiment of the invention; FIGS. 3 and 4 schematically represent plug variants and FIGS. 5 and 6 are sectional views of FIG. a connector according to a second example of implementation of the invention. The example of Figure 2 shows a connector 1 according to a first embodiment of the invention. This connector 1 differs inter alia from that shown in FIG. 1 in that the plug 5 extends along the X axis for a distance that may be equal to 100% of the length of the body 2. As will be seen from FIG. continued, particularly in connection with Figure 4, in. other examples, the plug may extend over a distance greater than 100% of the length of the body, for example 200%. In the examples considered, the plug 5 does not extend only around the portion of the body 2 defining the connection interface intended to come into contact with a complementary type connector during connection operations. In this example, the central contact 4 is a separate element of the body 2, being placed in the body 2. As can be seen in Figures 2 and 3, the cap 5 may comprise along the first longitudinal axis X a portion tubular front extending from the longitudinal end 1.1 before the plug 5 to a shoulder 12. This front portion 10 is for example arranged around the connection interface of the body 2. The front portion 10 is, in the illustrated example, grooved, having between one and ten grooves 13 which may or may not be regularly spaced relative to each other. The plug 5 further comprises in the example of Figures 2 and 3 along the X axis a rear portion 14 defined between the shoulder 12 and the rear longitudinal end 15 of the plug 5. As can be seen in Figures 2 and 3, this rear portion 14 has a hole 16 that can ensure the maintenance in the cap 5 of the body 2 by snapping a leg of the body 2. The ratio between the length 1, the front portion and the length 12 of the rear part can be any, which can take any value between 0.25 and 4, in particular 1. The rear part of the cap 5 also comprises in the illustrated example two reliefs 17 being ribs extending towards the longitudinal end back 15 of the cap.

These ribs 17 have, as can be seen in Figures 2 and 3, a height which increases when one approaches the rear longitudinal end 15 of the cap. In the example of Figures 2 and 3, the surface of these ribs is irregular, having streaks 18 but the invention is not limited to such a surface example of the ribs. As shown in FIG. 3, the width L of the ribs 17 measured perpendicularly to the first longitudinal axis (X) of these reliefs may also increase as one approaches the rear longitudinal end 15 of the plug.

As can be seen in Figures 2 and 3, the rear portion 14 of the plug has in section a substantially polygonal shape defining a housing 19, for example star whose role will be described later. The cap 5 also comprises, as can be seen in FIG. 2, on one of its lateral faces, an opening 18 allowing the barrel 6 of the body 2 of the connector 1 to pass through. The example of FIG. 4 differs from that of FIG. Figures 2 and 3 by the presence beyond the rear longitudinal end 15 of the cap 5 of a gripping portion 20. This gripping portion 20 is in the example described in the form of a tongue.

The gripping portion 20 may be made in one piece with the plug 5 by molding material, be overmolded on the plug 5 or be reported by any mechanical fastening means, for example by riveting, screwing or ultrasonic welding on the cap 5. As can be seen in FIG. 4, reliefs 22, for example, knurling may be provided by at least one face of the gripping portion 20.

Although in the example considered, the gripping portion 20 extends along the first longitudinal axis X of the body, it could alternatively extend obliquely with respect to the X axis or not extend rectilinear way. The gripping portion 20 may be made of a flexible material, for example PU, TPE-U or TPU. As in the example of Figures 2 and 3, the housing 19 in the plug 5 shown in Figure 4 has a portion at the rear portion 14 of the plug 5 having a polygonal section, in particular star-shaped. In the examples which have just been described, the stopper 5 is made of plastics material, for example comprising a dye. The plug 5 may be made by plastic injection, in the example of FIGS. 2 and 3, or by bi-injection of plastics in order to also perform the gripping portion 20 in the example of FIG. 2 to 4, the body 2 of the connector can be made by machining, the body then forming the mass contact. The invention is however not limited to such an example. In examples not shown, the body is made by molding plastic material (s) and the insulation is made in one piece with the body 2. The mass contact is made by metallization of the outer surface of the body. body 2. The central contact 4 may be a separate piece introduced into the housing formed inside the body or, alternatively, be formed by metallizing the inner wall of this housing, as explained in the application filed by the Applicant in France under number 09 55817. The metallization of surfaces to form the mass contact and / or the central contact can be made according to the teaching of this application filed in France under the number 09 558117. We will now describe with reference to FIGS. 6 a connector according to another example of implementation of the invention. In this example, as can be seen in FIG. 6, the body 2 is made according to the teaching of the application FR 09 55817. The body 2 and the insulator 3 form a single piece and the surface of the body 2 has a metallized coating with the exception of a zone 30 of the wall 31 of the housing 32 formed inside the body 2 and configured to receive the central contact 4. The zone 30 is called "savings zone".

The body 2 comprises, at the connection interface 35 means configured to perform centering and / or support functions, including locking, when connecting the connector 1 to a complementary type connector which is shown 5 in the form of a base 36. The means of the connection interface 35 are in the example shown beams but the invention is not limited thereto.

The connector 2 is in the example considered bent and the rear longitudinal end of the body 2 is closed by a shielding cap 40 attached to the body 2. It is shown in Figure 5 the propagation of the radio frequency signal S when the connector 4 is connected to the complementary type connector 36. As can be seen, the signal S is confined in the connector 1 between the central contact 4 and the ground contact 41 defined by the metallized outer surface of the body 2. The presence, at the height of the savings zone 30 at least of the plug 5 protects the mass contact 41 in this savings zone 30.

In the example of FIGS. 5 and 6, the portion 100 of the body 2 around which the plug is located extends from the front end 8 of the body 2 to the cover 40, this portion 100 comprising the connection interface 35 and the portion up to the savings zone 30 other than the connection interface. The invention is not limited to the examples which have just been described.

In particular, although in the examples described, the plug extends along the axis X over the entire periphery of the body 2, the cap could extend only partially on said periphery.
