Definitions
- the present invention relates to a miniature coaxial switch or inverter connector in particular for electrically connecting a transmitter element to a pair of antennas.
- a switch connector of the type targeted by the invention is described in US Patent 5,174,775 and EP 0 497 704.
- This switch connector is used in particular for connecting a car portable telephone to the antenna thereof.
- this phone When this phone is used in portable mode outside the car, it is necessary to disconnect the antenna from the car, so that the phone can operate with its own antenna and its own power source.
- the radio frequency range transmitted by this type of switch connector is between a few hundred MHz and 3 GHz.
- the purpose of the present invention is to provide a coaxial switch or inverter connector having a simple structure, compatible with the requirements of miniaturization, facilitating surface mounting on a printed circuit board, while allowing the transmission of frequencies included in the range. above.
- the invention thus relates to a miniature coaxial switch or reversing connector, in particular for electrically connecting a transmitting element to a pair of antennas, comprising a hollow body from which at least two contact elements protrude, inside which is mounted so axially movable a plunger having, at one of its ends, an electrical contact element, this plunger being biased by means of return to a first position in which an electrical contact is established between the two contact elements and said plunger being movable against the action of the return means to a second position in which the electrical contact element is in electrical contact with the one of the two contact elements and the latter are electrically isolated from each other, characterized in that the two contact elements are contact blades located in the same plane and allow the connector to be mounted on the surface d 'a printed circuit.
- the axial plunger thus simultaneously moves the end contact element intended for example to be connected to a car antenna, between a projecting position and a retracted position, and establishes contact either with one of the contact blades or with the two blades.
- Such a construction is therefore simple to make and to miniaturize so that it can be mounted on a printed circuit board.
- the parts of the contact blades projecting from the hollow body are located without a plane perpendicular to the axis of the plunger. Such an arrangement facilitates surface mounting of the switch connector.
- the switch or inverter connector advantageously comprises an outer casing made of conductive material, for example metal.
- it comprises a ground blade cut out from said housing, situated in the plane of said projecting parts of the contact blades.
- FIG. 1 is a sectional view along its axis of a switch connector according to the invention
- FIG. 2 is an elevational view with cutaway of the switch connector of Figure 1;
- - Figure 3 shows a half-view along the plane III-III and a half-view along the plane IV-IV of Figure 1;
- FIG. 4 is a view similar to Figure 1 showing another position of the plunger;
- FIG. 5 is an exploded perspective view of the switch connector of Figure 1;
- FIG. 6 is a view similar to Figure 1 showing a variant of the switch connector;
- Figure 7 shows another variant of the switch connector according to the invention.
- the miniature surface-mounted coaxial switch connector in particular for electrically connecting a transmitting element to an antenna, comprises a cylindrical hollow body 1 from which two contact blades 2, 3 and one or two protrude ground blades 4, 4a, allowing surface mounting.
- a plunger 5 made of electrically insulating material carrying at one of its ends an electrical contact element at the end 6.
- the plunger 5 is urged by return means 8 to a first position (that shown in FIG. 1), in which the end contact element 6 projects at one end 7 of the hollow body 1 and an electrical contact is established between the two contact blades 2 and 3.
- the plunger 5 is movable against the action of the return means 8 to a second position (that shown in FIG. 4), in which the electrical contact element at the end 6 is erased from the end 7 of the hollow body 1, is in electrical contact with one 2 of the two contact blades and the two blades 2, 3 are electrically isolated from one another.
- the contact blade 2 is for example connected to the high frequency transmitter of a car portable telephone.
- the end contact 5 is in this example, intended to be connected with a car antenna.
- the other contact blade 3 is connected to the antenna belonging to the mobile phone.
- FIG. 3 shows that the parts of the contact blades 2, 3 protruding from the hollow body 1 are situated in a plane perpendicular to the axis XX 'of the plunger 5.
- the switch connector comprises an outer casing 9 made of conductive material such as metal.
- This housing 9 comprises one or two ground blades 4, 4a (see FIG. 2) cut out of the housing, situated in the plane of said projecting parts of the contact blades 2, 3 (see FIG. 3).
- the end contact element 6 projects, in said first position, into a cavity 10 formed, at one end of the hollow body 1, in an electrically insulating material 11 lining the interior of the hollow body 1.
- the plunger 5 comprises, opposite the end contact element 6, a plate 12 perpendicular to the axis XX 'of the plunger 5 supported by one 12a of its faces on a return spring 8 in abutment against the bottom 13 of the hollow body 1.
- the other side of the plate 12 comprises an electrically conductive element 14 which, in said first position of the plunger 5, establishes electrical contact with parts of the contact blades 2, 3 situated in a plane parallel to the plate 12.
- the part 2a of the blade 2 directed towards the end contact element 6 is a sleeve coaxial with the plunger 5 and of greater diameter with end contact element 6.
- This sleeve 2a has (see FIGS. 2 and 5) two elastic tongues 15, 16 cut from the sleeve and the ends 15a, 16a of which are adjacent to the end contact element 6 are brought closer to the axis XX 'of the plunger 5.
- the ends 15a, 16a of the tongues 15, 16 can thus come into contact with the end contact element 6 when the plunger 5 is in the second position shown in FIG. 4.
- FIG. 5 represents the detailed shape of each part of the switch connector .
- the insulating interior lining is in two parts 11 and 11a superimposed; - that the upper insulating lining includes pins 11b which can engage in holes 2c made in the blades 2 and 3 and in holes 11b formed on the upper edge of the lower lining 11a; which provides excellent positioning of the blades 2 and 3; - That the housing 9 has tabs 20 whose ends 20a are folded under the bottom of the insulating block 11a.
- FIGS. 1 and 4 also show that the interior insulating lining of the hollow body 1 is in two parts 11, 11a bearing on one another along the plane in which the two contact blades 2, 3 extend.
- the part 11 of the insulating lining situated opposite the plate 12 of the plunger 12 forms in the above plane two shoulders 21 parallel to the plate 12 against which the two contact blades 2, 3 bear.
- the part of the blade 2 directed towards the end contact element 6 has at its end a part in the form of a washer 22.
- the opening 22a of this washer 22 is engaged the part 5a of the plunger 5 situated between the plate 12 and the end contact element 6.
- the position of the washer-shaped part 22 is such that it can come into contact with the end contact element 6, when the plunger is in the second position, that is to say when the element 6 is deleted.
- the conductive part 14 could be circular, which would avoid having to keep it in rotation.
- the switch connector that has just been described can be used in a car telephone installation, to connect the radio transmitter to an external antenna.
- the socket of this external antenna comprises a coaxial plug, the central contact of which comes into contact with the contact element 6.
- the contact element 6 projects into the cavity 10 and the ends of the contact blades 2, 3 are in contact with each other, as indicated in FIG. 1.
- the phone works with its own antenna and can be used outside the vehicle.
- the central pin of the latter comes into contact with the contact element 6 and pushes the latter towards the interior of the hollow body 1.
- the plate 12 then moves away from the contact blades 2 , 3.
- the end contact element 6 comes into contact with the lamellae 15, 16 of the contact blade 2, thereby establishing an electrical connection between the latter and the end contact element 6.
- the switch connector according to the invention has a diameter of around 6 mm. Its projecting blades 2, 3, 4 located in the same plane facilitate its mounting along the axis XX 'of the connector on a printed circuit board.
- the contact element 6 could always be supplied, that is to say always in electrical connection with the contact blade 2. This result can be obtained by increasing the length of the contact element 6 so that in the position of Figure 1, it is in contact with the part 2a.
- the plunger 5 carries an end contact element 5a which is clearly set back relative to the end 7 of the hollow body 1.
- one 2 of the two contact blades 2, 3 is extended by a part 2a moving away from the plate 12 and directed towards the end contact 5a of the plunger 5. Therefore, when a pin connection external 6a is pressed into the hollow body 1, this is first in electrical contact with the part 2a directed towards the end and going beyond the contact end at the end 5a of the plunger, then pushes on the contact end 5a of the plunger 5.
- the part 2a of the blade directed towards the end contact element 5a is a sleeve coaxial with the plunger 5 and of diameter equivalent to the latter.
- This sleeve 2a has elastic tongues coming into contact with the external connection pin 6a before the plunger 5 is in said second position.
