Description

The present invention relates to a coaxial connector. This coaxial connector is for example QM.A type or MCX type, but the invention is not limited to a particular type of coaxial connector. The invention applies, for example, to coaxial connectors in the medical field, in the aeronautical or transport field, in the space sector or in the field of telecommunications. The coaxial connectors include a body, a mass contact and a central contact received in the body with the interposition of an insulator. He is known. to make such coaxial connectors, to use separate and metallic pieces 10 to make the body. the central contact; mass contact and insulation. Such connectors can be relatively complex to assemble. relatively high production cost and significant weight. US Pat. No. 5,860,812 discloses a connector intended to be mounted on a device, for example a printed circuit board or a panel, comprising a body made in one piece with the insulator and a ground contact made by metallization of body parts. There is a need to benefit from coaxial connectors, in particular intended to be mounted on a coaxial cable, which are of relatively simple design. 20 inexpensive to manufacture and reduced weight. The invention aims to meet this need and it achieves in one of its aspects through a coaxial connector comprising: a body. a ground contact, a central contact, and an insulator interposed between the central contact and the ground contact. the insulation being made in one piece with the body, said body having at least one metallized portion defining the mass contact and the body having a housing for receiving a coaxial cable. Such a connector has a small number of parts. thus reducing the number of assembly steps and the manufacturing cost.

The body is advantageously made by molding at least one plastic material. The plastics are for example chosen from technical thermoplastics such as PEI, PU, PBT. REEK, LCp, .... Such connector plastic material (s) may have a reduced weight. The diversity of plastics that can be used can make it relatively easy to manufacture a connector of reduced dimensions. Indeed, the electrical performance of a connector being strongly related to the electrical characteristics of the materials used in particular for the insulator (electrical permittivity, loss factor), the wide choice of plastics. 1.0 in particular available thermoplastics makes it possible to move the metallization plane (s) corresponding (s) to different connector interfaces without changing the outer diameter but only choosing the material judiciously to maintain the impedance matching. This also makes it easy to change the locking function of a connector without having to compromise with electrical performance but only by modifying the material in order to readjust the impedance. It is also easy to adapt the coaxial line by geometric modification of the body structure (complex geometric configurations). The manufacture of the body by molding can therefore make it possible to produce complex shapes (incorporating numerous changes in external diameters of the mass contact) suitable for producing certain coaxial microwave components. for example filters or attenuators. These complex shapes are relatively expensive and difficult to achieve by machining (many important operations). The use of a plastic material in place of metallic materials can also give the coaxial connectors obtained a better corrosion resistance, making it possible to reduce the risk of degradation of the contact resistances of the connector, the connector part or parts thereof. plastic material is not likely to aggravate corrosion when corrosion spots appear at the metallized portions of the coaxial connector. contrary to the case where metal parts are used (propagation phenomenon, piguration, corrosion, galvanic corrosion). A coaxial line must maintain a constant impedance. Since the impedance of the line is, inter alia, dependent on the distance d between the central contact and the ground contact, the impedance matching is facilitated in the case of a connector made according to the invention by molding because it becomes easy to modify this distance d by moving the metallization plane representing the mass contact and / or the metallization plane representing the central contact without introducing problems related to the mechanical assembly of the machined parts. This also allows the adaptation of the line without increasing the outer dimensions of the connector. When the coaxial connector is intended to be mounted on a coaxial cable, the use of one or more plastics may also improve the performance in terms of retention on the cable of the connector, the plastic IO having, for example, elastic properties after fixation, for example by crimping, of the connector on the coaxial cable,. outraged. the mass contact being defined by a metallized portion of the body of plastic material (s), this mass contact can have a satisfactory elasticity, making the connector less subject to. risks of rupture. This is particularly advantageous when the ground contact consists of a flexible and resilient end necessary for the latching function. A connector according to the invention is advantageously recyciable. being composed of one or more plastics themselves recyclable and a metal coating on at least a portion that can be recovered and removed. The metal coating is suitably in accordance with the RoHS Directive. The plastic material is advantageously filled with fibers, for example fibers chosen from glass fibers, carbon fibers and other metallic or ceramic additives. The glass and carbon fibers make it possible to reinforce the mechanical and thermal strength of the plastic material, the metal additives make it metallizable, the ceramic fillers improve their electrical properties. The body extends for example along a first longitudinal axis and advantageously comprises a fit (front portion of the connector coming into contact with the complementary connector) extending around said first axis. said barrel advantageously comprising at least one metallized wall defining the mass contact. The barrel may extend all the way around the axis of the body. In. variant. the barrel is defined by a plurality of cantilevered beams along the. first longitudinal axis of the body.

The plurality of beams can comprise first beams comprising locking means of the connector on a complementary type coaxial connector and second beams comprising means for guiding and centering the connector when coupling the latter to the coaxial connector type complementary. The connector can be bent. in which case the first longitudinal axis makes an angle. substantially equal to 900 for example, with a second longitudinal axis of the connector. In a variant. the connector is straight. in which case the first longitudinal axis is runic longitudinal axis of the connector. The connector advantageously comprises a cavity extending along the first longitudinal axis in a median area of the body. According to a first embodiment of the invention, the central contact is a separate piece reported in the cavity. According to a second embodiment of the invention, the inner wall 15 of the cavity is metallized, this metallized wall defining the central contact of the coaxial connector. The cavity may have a variable width along the first longitudinal axis. According to another aspect of. the invention .. said body comprises metallized portions defining the central contact and the ground contact of the connector. Such a connector may have a reduced number of parts. the body acting as an insulator and, through separate metallized portions, central contact and mass contact. Such a coaxial connector may be intended to be mounted on a coaxial cable. In a variant. such a coaxial connector is for example intended to be mounted on a printed circuit board, a panel or serves as a shielding housing for the design of microwave components. The coaxial connector can be straight or angled. The coaxial connector advantageously comprises a cap adapted to be ptace around a longitudinal extremate of the body. The coaxial connector is for example of QMA or MCX type. Another object of the invention is, according to another of its aspects, a. method of manufacturing a coaxial connector, comprising the following steps: - by molding a plastic material (s) the same part defining the body and the insulation of a coaxial connector and proceed to the selective metallization of said piece according to the so-called bulk technique: The pieces are arranged loose for example in a perforated barrel which will be immersed in a plating bath and kept rotating at a certain speed or in a basket to immerse (manual mixing of the pieces) of in order to obtain at least one metallized portion of said piece, said metallized portion or portions defining the ground contact of the connector. the method according to the invention may be less expensive than the processes comprising the steps of machining the metal components of the connector; surface treatment of said metal components and assembly of the components thus treated. The metallization processes of plastics are now well known, particularly for the cosmetics markets. automotive, aeronautics. The production of these generally bulky plastic parts is done today by a piecing process: each part is arranged manually on a branch of a metal shaft which will be immersed in the metallization bath. Unlike this known process for metallizing plastic parts, the metallization of the connector will be performed by a so-called bulk technique advantageously barrel .. more suitable for complex parts of small size. This barrel technique, widely used and easy to implement for the treatment of metal parts, is however much more complex for the treatment of plastic parts, the barrel to be made of a non-metallizable material. The selective metallization step may be carried out subtractively. The surface of the part can be metallized then, only the metallized coating of portions intended to define the mass contact and, where appropriate. the central contact, can be preserved by subjecting the other portions of the surface of the room to a thermal ablation, including laser, or mechanical. Alternatively, the selective metallization step is carried out by saving, the part being made by hi-injection of two plastics of which one of them can not be metallized. The selective metallization step may then be devoid of a subsequent thermal or mechanical ablation step.

Subsequent to the selective metallization step, the method may comprise the step according to which, in a cavity formed in said part, a metal piece acting as a central contact of the coaxial connector is brought back. In a variant. at the end of the metallization step. selective. at least a portion of the part defining the body and the insulator of the coaxial connector, distinct from those defining the ground contact, is metallized, said portion defining the central contact. coaxial connector. It is useful to choose a suitable electrolytic and / or chemical finish in order to be able to metallize holes of very small diameter, which is necessary in particular when the central contact of the connector is defined by a metallized portion of the part, a central contact and realized satisfactorily ensuring the electrical continuity between the front and the back of the connector. The process can be carried out using one or two abalone or a basket. The step of selectively metallizing the part defining the body and the insulation of the coaxial connector may comprise the following sub-steps: chemical etching or sandblasting, activation of the surface of said part for example by a solution of palladium, - chemical plating, - chemical and / or electrolytic finishing, drying, - laser ablation or mechanical machining of portions of the surface of said part not intended to be metallized, - cleaning of the surface of said part, and - drying. According to another example of a method according to. According to the invention, the selective metallization step comprises the following sub-steps: 1) injection of two plastics, one of which is not subject to metallization having previously been carried out to form a part defining the body; and the insulator of the coaxial connector chemical etching, - sensitization of the surface of said part by a pre-coppering, copper-plating, chemical and / or electrolytic finish, and drying. The metallization process advantageously complies with the REACH regulation. Other advantageous properties and. characteristics of the invention can be better understood from the description that goes. follow nonlimiting examples of implementation thereof and the examination of the accompanying drawing in which: Figure 1 shows schematically in axial section a connector 1.0 according to a first example of implementation of the invention - Figure 2 shows a variant of the connector shown in Figure 1, Figure 3 shows a connector according to a second example of implementation of the invention, - Figure 4 represents pan. connector as shown in Figure 1 or Figure 3, and - Figures 5 and 6 show schematically examples of methods of manufacturing a connector according to the invention. There is shown in Figure 1 a coaxial connector generally designated 1 according to a first embodiment of the invention. This connector 1 is in the example described a bent connector, for example QMA, but the invention is not limited to such an example, as will be seen later. This connector 1 comprises a horn designated generally 2. The body 2 is made of one or more plastics, for example selected from technical thermoplastics such as PLI, PPS. PBT, PEEK., LCP .... The plastics can be loaded with fibers and can be chosen to combine the performance of high resistance to mechanical stress and thermal stresses. The connector also comprises an insulator 20 which is made in one piece with the body 2. The body 2 comprises in the example of Figure 1 a first tubular portion 3 having an end 5 intended to come into contact with a coaxial connector 7 complementary type generally designated by 4 when coupling these two coaxial connectors 1 and 4. The first tubular portion 3 extends along the first longitudinal axis X. As can be seen, the first tubular portions 3 may comprise at its longitudinal end S a barrel 6 extending cantilever about the axis X. The fact 6 has an inner wall 7 and an outer wall 8. The latter may or may not extend so Continuous about the X axis. The first tubular portion 3 may be devoid of its longitudinal end opposite the opening end 5 allowing access to the interior of the body.

As can be seen, locking means 10, for example a shoulder, may be formed on the inner wall 7 of the eye 6 to cooperate with complementary locking means, for example a groove and a shoulder, formed on the surface. 4. In the example illustrated, the inner walls 7 and outer 8] of the barrel are metallized, so as to define the ground contact of the coaxial connector 1. The body 2 comprises a second portion I l s extending along a second longitudinal axis Y, which is in the example described perpendicular to the axis X, As shown, a housing 12 intended to receive a coaxial cable may be formed inside the second portion 1.1, this housing 12 being extended according to Faxe Y by a conduit 13 communicating with a cavity 14 formed inside the first portion. tubular 3. in a median region thereof, said cavity 14 extending along the X axis As shown the core 15 of the stripped coaxial cable whose role will be described later is received in the conduit 13. The cable coaxial is held by welding inside the housing 12.

The coaxial connector 1 comprises a central contact 17 intended to cooperate with the central contact of the coaxial connector of the complementary type 4. In the example of FIG. 1, the central contact 17 is a metal part, for example made of CruBe2, reported in FIG. cavity 14. This central contact 17 has on its lateral surface harpoons 18 to ensure its maintenance inside the cavity 14.

The central contact comes into contact at one of its V-shaped longitudinal ends 19 with the core 15 of the coaxial cable, thus ensuring electrical continuity when the coaxial cable is received in the housing 12. The coaxial connector 1 can still include a plug 21 to be mounted on the barrel 6_ this plug having for example an opening for the passage of the connector 4 of the complementary type, as shown in Figure 1, This plug. provides an additional locking function of the interconnection thus produced and also improves the retention of the connector relative to the complementary connector.

In the example of the figure, the coaxial connector is a straight connector of the MCX type extending along a single longitudinal axis X. The coaxial connector 1 comprises, as described with reference to FIG. 1, a centralized contact 17 on the body. 2, an insulator made in one piece with the body 2 and a mass contact defined by metallized portions of the fiat 6.

In the example shown, the rear portion 24 of the body 2 defines the housing 12, the rear portion 24 being intended to be received in a sleeve 25 (iron-ruie in English) for attachment to the coaxial cable not shown. FIG. 3 shows a second example of implementation of the invention.

In this example, the coaxial connector 1 is an angled connector type () MA niais could alternatively be a straight connector, for example an MCX type connector or any other type of connector. With respect to the connector shown in FIG. 1, the coaxial connector 1 shown in FIG. 3 comprises a central contact 17 defined by the metallized inner wall of the cavity 14 of the body 2 and not by a metal piece attached to this cavity 14. The cavity 14 has in this example when moving along the axis X of the end portions 30 and 31 narrower than the intermediate portion 32. The end portion 31 opens into the conduit 13 of which the access to the outside is closed by a removable cover 35 placed at the longitudinal end of the first tubular portion 3 opposite the longitudinal end 5. The access proposed by the conduit 13 pe net the insertion of tools for the soldering the cable core to the central contact. As can be seen in FIG. 3, the wall defining the cavity 14 can extend as far as the inside of the duct 1.3. FIG. 4 shows a coaxial connector 1 as represented in FIG. 1 or in FIG. 3. In this example, the lug 6 does not extend continuously over the periphery of the X axis. In this example again, the piece 6 comprises a plurality of first beams 40 and second beams 41 which are in the example described arranged alternately all around the X axis of the connector. The first beams 40 comprise. as can be seen, on their side facing the inside of the connector a locking relief 10 intended to cooperate, for example by snapping. with a groove of the complementary type connector 4. The second beams 41 comprise for example a portion projecting towards the inside of the connector and extending along the axis X. the distance between the axis of the connector and this portion protruding being for example equal to the outer radius of the part of the complementary type connector 4 intended to be received inside the barrel 6 during the coupling of the two connectors. In the example shown in FIG. 4, the coaxial connector 1 is an angled connector of the QM.A type, but in a variant, a straight connector could comprise first and second beams as shown in FIG. FIG. 5 is a first example of a method of manufacturing a connector according to the invention. The method shown in Figure 5 can be used to make a connector as shown in Figures 1, 2 or 3, for example. In a first step 100. a plastic material is injected so as to form the part defining the body 2 and the insulator. A step 101 is carried out at the selective metallization of said workpiece so as to define the ground contact and, where appropriate, the central contact of the coaxial connector 1. This step 101 comprises the following sub-steps - at a sub-step. step 102, a chemical etching or sandblasting of the workpiece surface is performed, at a sub-step 103, the surface of the body is activated, for example by a palladium solution, at a sub-step 104, a chemical copper plating of the surface of the piece is carried out. in a sub-step 105, a chemical and / or electrolytic finish is carried out, for example nickel. at a sub-step 106, the part is dried, at a sub-step 107. a thermal ablation is carried out, in particular by laser. or a mechanical machining of portions of the surface of the workpiece not intended to be metallized. This sub-step 107 makes it possible to obtain the selectivity of the metallization of the part. this selectivity being in particular necessary for the good electrical and microwave operation of the connector, at a sub-step 108 the surface of the part is cleaned and, at a sub-step 109, the drying is carried out of the connector surface. Another method example, which is particularly suitable for the manufacture of a connector according to FIGS. 1 2 3 or 4, will now be described with reference to FIG. 6. At a step 110, a hi-injection of a standard plastic material (FIG. non-loaded with metal additives) and a plastics material filled with metal additives is carried out, In a step 111. it is carried out the selective metallization of the piece obtained at the end of step 110. de way to define the mass contact and. where appropriate, the central contact of the coaxial connector 1 This step 111 comprises the following sub-steps: at a substep 112. the chemical etching of the surface of the workpiece is carried out at a substep 113 the surface of the part is sensitized by pre-coppering to facilitate adhesion of the deposits for the following steps. in a sub-step 114, the surface of the part is chemically copper-plated, at a sub-step 115, the chemical and electrolytic finish is carried out, and a sub-step 1.16, it is proceeded to drying the part defining the body and the insulation of the coaxial connector.

According to the method which has just been described, it is not necessary to obtain a selective metallization of the surface of the part defining the body 2 and the insulator. to use a thermal ablation step or mechanical machining. The selectivity of the metallization is ensured by saving only the portions of the surface made by injection of the plastic material loaded with a metallic additive being metallized. Steps 102, 103, 104 and 105, or steps 112, 113, 114 and 115 can be made according to a so-called bulk technique, advantageously to the barrel. The methods described with reference to FIGS. 5 and 6 can be carried out using a single barrel used to carry out the entire protection.

As a variant, two distinct barrels can be used to implement the method according to FIG. 5 or the method according to FIG. 6. A barrel being for example dedicated to the preparation of the surface of the part according to the steps 102 and 103 or 112 and 113 and another barrel being dedicated to chemical deposition and electrolytic finishing according to steps 104 and 105 or 114 and 115.

In steps 102, 103 and 104 or 112, 113 and 114. the rotational speed of the barrel is for example very slow, this speed being able to be increased for the electrolytic or chemical finishing step according to steps 105 or 115. 'invention. allows to obtain a coaxial connector a number of parts and a reduced cost and addresses for example the market of the connectors in the medical field, providing a solution to the non-magnetic behavior, because of the complete control of the material and the coating in terms of magnetic pollution (no contamination from ferrous particles from the machining process). The invention can also be applied to the market of aeronautical connectors or for transport, particularly because of the weight gain it provides and which can reduce consumption. The invention can still be applied to the connectivity industry for the space domain, making it possible to compensate for multi-factor effects and to reduce the payload of the satellites. The invention can still be applied to the market of the connectors in the field of telecommunications, because of the gain in terms of manufacturing cost; transportation and assembly.

The connector according to the invention can be spread in duplex version. triplex, quadriplex, ... by duplication of the internal structure within the same body thus presenting different interfaces. The expression "comprising a" shall be understood as "containing at least one", except where the opposite is specified
