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 being open at any time, which would be damaging for the current transformer.
  • the actuating element is often made in the form of a finger or a rod of insulating material to push back a part in the form of a bar which normally short-circuits two fixed contacts of the switch by being returned to position closing by a spring.
  • Such arrangements have, as drawbacks, a certain fragility of the actuating element, a rapid deterioration of the switch contacts when the shapes of the bar and of the switch terminals cause them to be in contact only linear or punctual, and the need to use a spring which can cause mounting and calibration problems.
  • the 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 provide these advantages with a structure that is 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 spring.
  • 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 shown 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).
  • 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 to 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 apex 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 forms 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 flexible arm 18a under the effect of its tension, changes from a rectilinear form to the form in arc 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 'These 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.
  • shoulder 21 In place of shoulder 21, or in addition to this one, it will be able to form a key by conferring on the rear part of the socket and at the entrance of the terminal housing of the dissymmetrical shapes corresponding to authorizing the complete insertion of the socket only if the latter is in the good 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.
