Definitions

  • This electrical contact block 100 serves as a component of a control and signaling unit. It allows you to establish or break an electrical contact. It finds a classic application for example in an emergency stop button. Such buttons are used in particular to quickly cut off the power supply to installations or machines in the event of an accident or damage.
  • the contact block 100 shown in the figures 1 to 3 is of the “normally open” type (NO type). It has two electrical terminals 101 and 103 which are integrated in a housing 102.
  • the housing 102 is provided with a fixing screw or nesting screw 104. Thanks to the fixing screw 104, it is possible to fix the contact block 100 to other components, such as example a button body.
  • a pusher 106 is arranged in a sliding manner in the housing 102.
  • the pusher 106 comprises an actuating head 108. By pressing on the actuating head 108, the pusher 106 is pushed into the housing 102. Thus, contact is established electrical between the two electrical terminals 101 and 103.
  • This known contact block 100 has certain advantages. It is stackable and compatible with push buttons and turn buttons. In addition, thanks to the pull-out screw, it has a very reliable means of fixing. In addition, its electrical insulation distances are sufficient for applications at a usual supply voltage of 230 V.
  • this known contact block has the disadvantage that it requires considerable height. Indeed, the pusher 106 must have a pronounced height, that is to say a slender shape, to ensure its smooth sliding in the guide cavity. If the height of the pusher is not sufficient, then it risks leaning into the cavity, which would cause the contact block 100 to fail. For it to remain functional, the known contact block 100 must therefore have a minimum height. Because of this minimum height, it is often impossible to stack more than two contact blocks 100 in the same control unit.
  • An aim of the present disclosure is therefore to propose a stackable electrical contact or signaling block, which, by its construction, does not have such a limitation as to its height and retains as much as possible the advantages of the known blocks described above. .
  • this goal is achieved by providing the electrical contact or signaling block defined in ⁇ [0001] with a device for guiding the pusher in the guide cavity comprising a guide tongue received in a complementary guide slot passing through the actuating head.
  • This guiding device in the form of a set of complementary tongue and slot, the slot passing through the actuating head, ensures precise and reliable guidance of the pusher, in particular when the latter is of low height. Thus, there is no longer any risk of the pusher bracing, which makes it possible to considerably reduce the contact or signaling block.
  • the U-shaped movable bridge is guided in its course by guide walls of the housing.
  • FIGS. 4 to 9 show an exemplary embodiment 100 of a stackable electrical contact block according to the present disclosure.
  • the electrical contact block 100 is intended to be integrated into a control unit. By operating the electrical contact block 100, electrical contact can be established between two electrical terminals contained in the contact block. In industrial applications, it is thus possible to supply electric current to an electrical installation.
  • normally open electrical contact blocks there are two types of electrical contact blocks, namely normally open electrical contact blocks and normally closed electrical contact blocks (“ normally open ”, or NO, and “ normally closed ”, or NC, in English).
  • the electrical contact block 100 of figures 4 to 9 is of the normally open type (NO type). Of course, the present disclosure also applies to normally closed type (NC type) electrical contact blocks.
  • the electrical contact block 100 includes a housing 102, a movable contact unit 104, a fixing screw 106, two electrical terminals 108, as well as a pair of return springs 110.
  • the housing 102 is made in two parts: a first part 102a and a second part 102b.
  • the two parts 102a and 102b can be separated, which allows access to the interior of the electrical contact block 100.
  • the second part 102b of the housing 102 is absent. In these figures, we therefore see only the first part 102a of the housing 102.
  • the first part 102a of the housing 102 accommodates the fixing screw 106.
  • the housing 102 delimits the volume of the electrical contact block 100. It has a substantially parallelepiped shape. It has upper 112 and lower 114 faces for connecting the electrical contact block 100 to another component. It also has an external face, 103, an internal face 105 and two lateral faces 107.
  • the external face 103 of the housing 102 is defined as the face located outside the battery when the electrical contact block 100 is stacked (see the figures 10 And 11 ).
  • the internal face 105 of the housing 102 is the face which is located in the center of the battery.
  • the upper face 112 of the housing 102 is the face by which the electrical contact block 100 is fixed to the rest of the battery during its assembly.
  • the lower face 114 allows another component to be connected to the electrical contact block 100 already stacked.
  • the housing 102 has several reception zones for the different elements of the electrical contact block 100. With reference to the figure 8 , we can distinguish a first zone 116 for receiving the electrical terminals 108, a second zone 118 reception of the mobile contact unit 104, A third zone 120 for reception of the fixing screw 106, and a fourth zone 122 for reception of the return springs 110.
  • the fixing screw 106 is received in a through hole 124 of the housing 102.
  • the fixing screw 106 is a nesting screw. That is to say that the head 126 of the screw 106 has a tapping 128. Thanks to the tapping 128, it is possible to connect another component to the electrical contact block 100, by screwing one screw on the other component in the thread 128. In particular, it is thus possible to connect or stack several electrical contact blocks 100 in this way.
  • the head 126 of the fixing screw 106 is located here on the side of the lower face 114 of the housing 102 .
  • the two electrical terminals 108 each include an electrical conductor 108a and a clamping screw 108b.
  • the electrical conductors 108a are installed in the housing 102 in the reception area 116. Using the clamping screws 108b, it is possible to connect an electrical wire to each conductor 108a.
  • Each conductor 108a is here made of a folded metal sheet.
  • Each metal sheet 108a has a fixing section 109 which cooperates with the clamping screw 108b, and an electrical contact section 111, preferably blade-shaped.
  • Each blade 111 carries an electrical contact point 113 at its free end.
  • the movable contact unit 104 is able to move inside the housing 102. It is shown in perspective in the Figure 9 .
  • This movable contact unit 104 includes a pusher 130, two spring stops 132, a bridge support 134, a movable electrical contact bridge 136 carried by the bridge support 134, and a movable bridge spring 138.
  • the pusher 130 comprises an actuating head 140 in the form of a wedge and a base 142 which carries the actuating head 140.
  • the pusher 130 has an external face 144, an internal face 146, and two lateral faces 148.
  • the wedge shape of the actuating head 140 is in the form of a triangle.
  • the actuating head 140 has the shape of an arrowhead. This particular form with two side ramps allows the pusher 130 to cooperate with both a push button and a turn button.
  • the electrical contact block 100 can be operated either by a push button or by a turn button.
  • the actuating head 140 behaves like a cam which makes it possible to transform a rotational movement of the turning button into a translation movement of the mobile contact unit 104.
  • each guide slot 150 is made in one of the side faces 148 of the pusher 130.
  • the guide slots 150 pass through the actuating head 140, and preferably also the base 142.
  • the pusher 130 has a substantially H-shaped cross section.
  • the cross section of the pusher is made up of two branches which are connected by a crosspiece. The gaps between the two branches correspond to the guide slots 150.
  • the pusher 130, the stops 132 and the bridge support 134 are made in the form of a single, single piece.
  • the pusher 130 supports the movable bridge 136.
  • the movable bridge 136 is a separate part from the pusher 130. Here, it has a substantially U shape (see the Figure 5 ).
  • the movable bridge 136 comprises a central contact plate 136a which is extended, at each of its ends, by a branch 136b for fixing the movable bridge 136 to the support 134.
  • the underside of the central plate 136a is shown in Figure 6 .
  • There are two electrical contact points 137 which are capable of cooperating with the contact points 113 of the electrical terminals 108 (see the Figure 5 ).
  • the movable bridge 136 is made of metal, since it must conduct an electric current.
  • the movable bridge spring 138 is a support spring.
  • the support spring 138 forces the movable bridge 136 downward and thus ensures reliable contact between the bridge mobile 136 and the terminals 108 during actuation of the electrical contact block 100.
  • the spring stops 132 serve to support the two return springs 110. They are located on either side of the pusher 130. In other words, the stops 132 frame the pusher 130. Each stop 132 is made in the form a tab which extends from the support 134 towards the external face 103 of the housing 102 (see the Figure 7 ).
  • Each return spring 110 is located next to one of the side faces 148 of the pusher 130.
  • the upper end 110a of each spring 110 rests on one of the stops 132 of the movable contact unit 104.
  • lower end 110b of each return spring 110 rests on a bottom 152 of the housing 102 (see the figure 5 ).
  • Each return spring 110 is received in a corresponding housing 122 of the housing 102.
  • the first part 102a of the housing 102 comprises a cavity 115 for guiding the pusher 130 (see the figures 7 And 8 ).
  • the pusher 130 is movably received in the guide cavity 115. It is able to move in translation in the guide cavity 115.
  • the guide cavity 115 has a rectangular cross section. It communicates with the rest of the housing 102 through an oblong opening 117.
  • the oblong opening 117 is in the form of a slot. It is defined by the extent of two guide tongues 119 which partly delimit the guide cavity 115.
  • the two guide tongues 119 are located opposite each other and separated by the oblong opening 117.
  • Each guide tab 119 is received in one of the two guide slots 150 of the pusher 130.
  • Each guide tab 119 has a shape complementary to that of its associated guide slot 150. In other words, each guide tab 119 is inserted into its complementary guide slot 150.
  • each guide tongue 119 comes from the material of the housing 102 and is therefore an integral part thereof.
  • the two electrical conductors 108a and the movable bridge 136 are located together in a breaking chamber 154.
  • the breaking chamber 154 is surrounded by an electrical insulation box which is part of the housing.
  • a lower section of the first part 102a of the housing 102 comprises a central receptacle 121.
  • This receptacle 121 serves to accommodate an actuation head of another component which is connected to the lower face 114 of the housing 102.
  • the actuation head receptacle 121 is here in the form of a rectangular enclosure.
  • the walls of the enclosure 121 are made in the first part 102a of the housing 102.
  • the guide tabs 119 extend into the enclosure 131.
  • the receptacle 121 defines therefore an electrical insulation cage which electrically isolates the inserted actuation head from the switching chamber 154.
  • This insulation cage includes a protector 123.
  • the protector 123 is made in the form of a guard plate.
  • This guard plate 123 masks a lower part of the guide cavity 115.
  • the guard plate 123 projects relative to the main body of the first part 102a of the housing 102. Thanks to the guard plate 123, a technician does not risk to be electrocuted if he inadvertently inserts one of his fingers or a metal part related to his fingers into the receptacle 121.
  • the pusher 130 By pressing on the actuating head 140, the pusher 130 is moved from a rest position to an actuation position (note that the figures only show the rest position). When moving towards its actuation position, the pusher sinks into the housing 102. In order to achieve this translation of the pusher 130, the resistance of the two return springs 110 must be overcome. The pusher 130, and consequently the movable contact unit 104, slides towards the lower face 114 of the housing 102, until establishment a mechanical and electrical contact between the contact points 137 of the movable bridge 136 and the contact points 113 of the electrical conductors 108a. As soon as the pusher 130 is released, it is returned to its rest position thanks to the action of the return springs 110. Thus, the movable bridge 136, which moves together with the pusher 130, breaks or establishes a electrical contact between the two electrical terminals 108.
  • the guiding device namely the two tongue/slot pairs 119,150, the back and forth of the pusher 130 within the housing 102 is well controlled.
  • the mobile contact unit 104 braces or gets stuck in the housing during its translation, in particular when the actuating head 140 is rotated by a turning button.
  • the guiding device with complementary tongue and slot minimizes the play and the degrees of freedom of the pusher 130. The latter is therefore forced to follow exactly the desired translation movement. This makes it possible to reduce the height of the pusher 130 and therefore the height of the electrical contact block 100.
  • the movable bridge 136 is guided by the partitions 156 which thus form walls for guiding the movement of the movable bridge 136.
  • THE figures 10 And 11 show an example of a control unit 200 comprising a stack of four electrical contact blocks 100 of the type illustrated in figures 4 to 9 .
  • the control unit 200 consists of a push button 202, a base 204, and a stack 206 of four electrical contact blocks 100.
  • Figure 10 is a side view of the control unit 200.
  • the Figure 11 is a longitudinal section.
  • the four electrical contact blocks 100 are connected to each other using their nesting screws 106. More precisely, the two upper contact blocks of the battery 206 are screwed with their nesting screws 106 into the lower face of the base 204.
  • the two lower contact blocks of the stack 206 for their part, have their nesting screw 106 screwed into a thread of a nesting screw 106 of one of the upper contact blocks.
  • the actuating heads 140 of the lower pushers are located in the receptacles 121 upper contact blocks. Also, the actuating heads 140 of the lower pushers 130 touch the bases 142 of the upper pushers.
  • THE figures 12 to 16 show an exemplary embodiment 300 of a stackable signaling block according to the present disclosure.
  • This is an indicator block capable of emitting a light signal to indicate an operating state of a control unit of which it is a part.
  • the indicator block 300 comprises a light guide 302, a housing 304, two pushers 306 with their return springs 308, two electrical terminals 310 with their tightening screw 311, two fixing screws 313, a printed circuit 316 carrying a diode electroluminescent 318, and a cover 320.
  • the housing 304 has upper 312 and lower 314 faces for connecting the indicator block 300 to other components, such as for example the electrical contact blocks 100 of the figures 4 to 9 .
  • the two pushers 306 of the indicator block 300 each have an actuation head 340 which has the same shape as the actuation head 140 of the electrical contact block 100 of the figures 4 to 9 .
  • the actuating heads 340 therefore also have a wedge shape and are crossed by two guide slots 350 facing each other.
  • the device for guiding the pushers 306 is comparable to that of the electrical contact blocks 100. We therefore also find, for each pusher 306, two guide tabs 319. As can be seen in Figure 15 , each pusher 306 also has a substantially H-shaped cross section.
  • Each pusher 306 has a stop element 332 serving as a support for its return spring 308. Note that the longitudinal axis of each return spring 308 is offset relative to the longitudinal axis of its corresponding pusher 306. Also, each return spring 308 is arranged laterally relative to its pusher 306.
