Definitions
- the present invention relates to a three-pole contact block, in particular breaking abrupt and positive opening, usable in a movement sensitive switch push button, especially a position switch, push button or the like.
- Such blocks usually include a housing which houses fixed parts of contact terminated at one end by connection pads and bringing to a other end a fixed contact, as well as a mobile equipment provided with several bridges contact so as to provide at least one pole with opening with the fixed contacts and a pole with closure.
- the moving team is requested on the one hand by a pusher, on the other hand by a spring system, the whole being arranged to produce a positive opening and a sudden opening and closing.
- the object of the invention is to allow a multipolar contact block to operate. with at least one switchable pole from the normally open state to the normally state closed or vice versa, without changing the arrangement of the contact carrier.
- connection pads are arranged in at least three separate connection plans, and the moving part has at least three bridges contact distributed so as to cooperate with fixed contacts located in two transverse planes of contact and to move in two frontal planes; of them contact bridges which are located in the foreground foreground cooperate with fixed outgoing contact parts on two connection planes, and the third bridge contact which is located in the second frontal plane cooperates with the fixed parts of outgoing contact on the third connection plane.
- the third connection plan is notably located in the middle position between the first two connection planes.
- the contact block is preferably three-pole and the moving assembly then presents four symmetrically balanced contact bridges, the fourth bridge contact being located in the second frontal plane and not cooperating with the parts fixed contact.
- the moving part may present in substitution for the fourth contact bridge a elastic or movable support piece located in the second frontal plane facing the third contact bridge located in this plane, to move at the same time as the contact bridge located in the same transverse plane.
- contact bridges located at different levels in a same frontal plane are stressed by a single compression spring tending to separate them from each other.
- the mobile assembly is mounted in the case by introduction via an open rear face of the case and a bottom is assembled, in particular snapped into place, to cover the rear face.
- the bottom may then have legs or similar holding elements which take support against fixed contact parts leading to the rear plane to contribute to keep them very simple.
- a terminal isolation cover can be reported, including snapped, on the front of the housing.
- the three-pole contact block shown in the figures comprises a housing 10 in insulating material which houses six conductive parts 11,12,13,14,15,16 carrying fixed contacts and a moving element 17 with positive opening and sudden movements opening and closing, the crew being guided in this box and equipped with movable contacts which cooperate with the fixed contacts.
- the housing 10 is of quadrangular shape and presents forward three groups of two terminals 21,22,23,24,25,26 distributed on three respective connection planes P1, P2, P3.
- Each terminal 21-26 has a cable clamping screw 27 (or a elastic clamping piece) cooperating with a connection pad 28 of the piece corresponding driver 11-16.
- the associated conductive parts 11, 12 and 15, 16 at terminals 21,22 and 25,26 located in the extreme connection planes P1, P3 are preferably identical to each other; the conductive parts 13.14 associated with the median terminals 23.24 of the median plane P2 differ from the other parts conductive and are preferably identical to each other (see Figure 6).
- the parts 11-16 end by a fixed contact 29 in the form of a pellet; contact pads 29 of the parts 11,12,15,16 are located in a rear frontal plane PR (parallel to the bottom and to the front face of the block and perpendicular to planes P1-P3) and those of parts 13,14 are located in a front plane PF parallel to PR.
- the pellets 29 of the parts 11, 12 are located in a plane P4 intermediate between P1 and P2 and those of parts 15, 16 are located in a plane P5 intermediate between P2 and P3; the pads of the parts 13,14 are located in the plane P4 or P5 depending on the configuration chosen for the block, as will be explained later.
- the housing 10 of the block offers a fixing lug 18, for example to be housed in a position switch body.
- the housing 10 is covered at the front by a cover snap-on 30 which provides a protective and waterproofing function for the terminals.
- the cover 30 has a wall 31 forming the front face of the block while providing access to the screws, as well as inter-terminal isolation partitions 32 and lateral detent notches on the front edges of the block.
- Case 10 presents at the rear an open face 33 which allows the introduction of the contact block and which is closed by a snap-on bottom 34.
- the bottom 34 has a flat wall provided, towards the inside of the block, with lugs 35 which hold the parts fixed rear contact 11,12,13,14. Instead of legs, one can provide shoulders or other similar forms of maintenance.
- the bottom 34 also includes snap tabs 36 on the housing.
- the moving element 17 is capable of generating a positive opening of the contacts. he comprises a pusher 40 movable in a direction Z parallel to the planes PF, PR and biased by a return spring 41, as well as a contact carrier 42 with movement abrupt also movable along Z.
- the contact carrier 42 is mounted movable back and forth on the pusher and is biased by a return piece 43. This piece of reference translates, by means of inversion of movement levers, a movement descending from the moving pusher rising from the contact carrier. Movement amount of contact carrier 42 is made abrupt using two lateral springs 44 at neutral.
- the mechanism described is known and is not the subject of the invention.
- the bridges 45,46 are symmetrically balanced on or in the contact carrier 42 so as to be able to move relative to this one according to Z.
- the planes of symmetry of the bridges are confused with the PF and PR frontal plans.
- the bridges 45,46 are located in the PR plane and the bridges 47.48 in the FP plan; 45.47 bridges on the one hand, and 46.48 bridges on the other hand, are located in two separate planes parallel to P1-P3, so that they can cooperate respectively with parts 11,12 (bridge 45), 15,16 (bridge 46), 13,14 (bridge 47 or bridge 48 depending on the assembly adopted for parts 13,14).
- Each bridge is provided in the middle with an overmolded insulating part 49 which facilitates its guiding in the contact carrier.
- a compression spring 50 is provided which bears directly on the bridges and tends to move them apart from each other to ensure a backlash and good pressure contact, mainly at the time of the changeover.
- an elastic or movable support piece 51 for example an elastic blade, capable of simulating, when the crew mobile 17 is activated, the crushing movement of the bridge to which it is substituted and follow the movement of the rear axle located on the same level.
- the bridges 45,47 form with the corresponding fixed contacts of the poles normally open (NO) and the bridges 46,48 form with the corresponding fixed contacts normally closed poles (NC).
- the described block mounts as follows.
- the fixed contact parts are arranged in the housing 10, then the mobile assembly is inserted from the rear into the housing and the bottom 34 is snapped onto the housing.
- the two configuration possibilities of the block are illustrated in FIGS. 3 and 4.
- the parts 13,14 fixed contact plates are arranged with their contact pads in the plan P4 to form a NO pole.
- the parts 13,14 are arranged with their contact pads in the P5 plane to form a pole NC.
- bridge 47 has been replaced by a part. elastic support for spring 50.
- Parts 13,14 of the NO version can be identical to parts 13,14 of the NC version, so that one passes from a version to the other by simple reversal, or they may be different.
- the housing 10 specific to the NO-NO-NC version of the contact block can be identical to the case specific to the NO-NC-NC version of the block or be different.
