Definitions

  • the subject of the present invention is a terminal assembly and plug-in socket on the terminal to be connected to a circuit on which the terminal is mounted, without opening the circuit.
  • a particular field of application of the invention is that of measurements to be made on a secondary of an intensity transformer, for example in the event of the appearance of faults.
  • the terminal is permanently mounted on the secondary of the current transformer, the switch being normally closed.
  • An intensity measuring device can then be connected in series to the secondary by means of the socket, without the secondary is open at any time, which would be damaging for the current transformer.
  • Terminal and plug devices of the type defined above are well known in the art. However, it turns out that these devices are not always suitable for the application envisaged above, in particular when the sockets are handled without particular precautions and with a certain precipitation - as in the case of an intensity measurement following the appearance of a fault - and when the current flows with a relatively high intensity under a low voltage.
  • the actuating element is often made in the form of a finger or a rod of insulating material to push back a piece in the form of a bar which normally short circuits two fixed contacts of the switch being recalled in the closed position by a spring.
  • bypass contacts are of the pin and socket type and have a quality which deteriorates over time.
  • the object of the present invention is to provide a robust assembly capable of being handled without particular precautions, with reliable contacts of unalterable quality both for the terminal switch and for the bypass contacts, this in order to avoid, in in the case of an application to a secondary current transformer operating at low voltage, any deterioration of the transformer due to poor contacts.
  • the present invention also aims to bring these advantages with a structure as simple and inexpensive as possible.
  • the robustness and simplicity of the device according to the invention are due to the use of a wide push-button carrying the second elements of the bypass contacts and to the absence of return springs.
  • the quality of the contacts results from the choice, for the switch, of a pressure contact, with contact elements such as pads, one of which is carried by a flexible blade, and, for the taps, of sliding contacts.
  • the assembly represented in FIG. 1 comprises a terminal 10 mounted on a circuit 11, 'for example the secondary of an intensity transformer (not shown) and a socket 30 connected by conductors 31, 32 to a measuring device , for example an ammeter (not shown).
  • Terminal 10 comprises a body 12 of insulating material, for example obtained by molding a synthetic resin.
  • a housing 13 opening towards the outside is formed in the body 12.
  • a switch 14 comprising two contact elements 15, 16 fixed to the ends of conductive strips 17, 18.
  • the contact elements 15, 16 are preferably silver pads welded to the strips 17, 18.
  • the blade 17 is embedded in the insulating material with the exception of its end carrying the patch 15.
  • the blade 18 is embedded in the insulating material of the body 12 with the exception of the section 18a located on the side of the bearing end the patch 16. At their other ends, the blades 17, 18 protrude from the body 12 for connection to the circuit 11.
  • the contact elements 15, 16 are housed in a recess 19 formed on one side 13a of the housing 13.
  • a shoulder 21 from which protrudes the section 18a of the blade 18 substantially parallel to the bottom of the housing 13 near this bottom.
  • the section 18a forms an elastic blade applying pressure with the contact element 16 against the contact element 15.
  • the blades 17, 18 are arched and have parts 17b, 18b which extend substantially parallel along the sides 13a, 13b of the housing 13, within the material of the body 12.
  • the contact elements 22, 23 can advantageously be formed by folded parts of the blades 17, 18 projecting from the material of the body 12 inside the housing 13 on each side 13a, 13b thereof.
  • the socket 30 comprises a body 33, also made of insulating material, the front part 34 of which forms a pusher of width slightly less than that of the housing 13 and the rear part 35 of which has a width substantially equal to that of the housing 13.
  • a body 33 also made of insulating material, the front part 34 of which forms a pusher of width slightly less than that of the housing 13 and the rear part 35 of which has a width substantially equal to that of the housing 13.
  • grooves 36, 37 are formed at the level of the junction of the parts 34 and 35 of the body 33, on each side of the latter.
  • Metal blades 38, 39 are partially embedded in the body 33. At one of their ends, the blades 38, 39 are electrically connected to the conductors 31, 32 at the rear of the socket 30.
  • the blades 38, 39 have parts 38a, 39a which project on two opposite sides 34a, 34b of the pusher 34 and are bent towards the rear of the socket with their ends 38b, 39b housed in the grooves 36, 37.
  • the parts 38a, 39a forming second bypass contact elements are held in position against the stress which tends to separate them laterally of the pusher 34.
  • the pusher 34 is asymmetrical and has an inclined front edge with a top 40 located near the side 34a.
  • the plug 30 When the plug 30 is inserted into the housing 13, it is guided by its rear part 35 sliding between the sides 13a, 13b.
  • the blades 38, 39 come into contact with the elements 22, 23 before the end 40 of the pusher touches the elastic blade 18a ( Figure 1).
  • the elements 22, 23 slightly repel the parts 38a, 39a and constitute with them two bypass contacts of the sliding and pressure type due to the stress to which the curved parts 38a, 3.9a of the blades 38, 39 are subjected.
  • the top 40 comes into contact with the elastic blade 18a near the switch.
  • the elastic blade extending transversely with respect to the direction of insertion of the socket, it is pushed back by the pusher 34.
  • the switch 14 is open and the elements of contact 22, 23 are located at the notches 41, 42 formed on the blades 38, 39 so as to maintain the grip 30 in the terminal 10.
  • the switch 14 closes before the opening of the bypass contacts. Any opening of the circuit 30 is thus avoided both during the connection and during the disconnection of the socket 30.
  • the flexible blade 18a and the blade parts 17b, 18b form a U which constitutes part of a loop which closes by the bypass contacts and has the effect of promoting the return of the flexible blade 18a in the closed position.
  • the arm flexible 18a under the effect of its tension, passes from a rectilinear shape to the arc shape and the substantially spherical contact pads roll on each other, which has the effect of automatically cleaning the contacts of the switch 14.
  • the bypass contacts they are also self-cleaning because they are sliding contacts.
  • the shoulder 21 forms a polarizing key against which the wedge 40 abuts, without being able to open the switch 14 when the socket is in an inverted position relative to its normal position.
  • a polarizing device by conferring on the rear part of the socket and at the entrance of the terminal housing corresponding asymmetrical shapes which do not allow the fully depress the plug only if it is in the correct position.
  • the assembly according to the invention is particularly simple and inexpensive because it comprises a minimum of parts. It can also operate in a wide power range.
