Description

Improvements to the shunting devices of several organs of

  electrical contacts The present invention relates to devices for shunting several electrical contact members. The invention relates to devices comprising a housing element provided with a series of channels

  intended to receive, each, an electric contact member

  female stick crimped at the end of an electrical conductor, each channel opening on a tab

  male connected to a shunt bar.

  In order to avoid any contamination which would interfere with good electrical contact, each channel, on the side of the introduction of the female electrical contact member, has a housing filled with a sealing gel, preferably a self-healing gel so , that once the electrical contact member has passed through the gel, it closes around the

  electrical conductor thus ensuring sealing.

  One of the drawbacks of this arrangement is that it is difficult to verify whether the female electrical contact members are perfectly

  installed and if the electrical connection is ensured.

  One of the aims of the present invention

  is to remedy these drawbacks.

  Improvements according to the invention,

  target shunting devices from several organizations

  nes of electrical contacts of the type comprising an element

  transparent housing with a series of

  channels each intended to receive a connector

  female electric tact engaged by a free end

  said channels, each member being crimped, at an ex-

  end, of an electrical conductor, the box element

  tier having, on the side opposite the free end of the channels, an imprint in which is housed a shunt bar comprising a series of tongues extending in the channels and intended to be inserted in the female electrical contact members, the channels being, near their free end, filled with a sealing gel, said improvements

  being characterized in that the housing element comprises

  te, to the right of each channel in the part containing

  sealing gel, a blind hole.

  Thanks to this arrangement, a tip of a tester can be engaged in the blind hole and through the sealing gel and the conductor insulation.

  in order to verify that the electrical contact members

  that females are properly mounted in the element

case.

  According to another characteristic, each electrical conductor, in its part intended to come in line with the blind hole, has a mark. So we can also have a visual check of the

  correct assembly of female electrical contact members.

  According to a constructive characteristic, the housing element comprises, at the level of each channel, a boss intended to cooperate with an opening of

  the corresponding female electrical contact member.

  Thus, it ensures a locking of the contact members

  electrical cables in the channels.

  According to yet another characteristic,

  each tab has a light and each organ

  no female electrical contact a retaining bar

  naked intended to engage in said light. Thus, a non-removable locking of the members is carried out

  of female electrical contacts in the channels.

  Finally, according to a constructive detail, the retaining bar and the opening are made on

  the same wall of the female electrical contact member

  the. S15 The invention will now be described

  in more detail with reference to a mode of reaction

  particular reading given by way of example only-

  ment and shown in the accompanying drawings, in which: Figure 1 is a perspective view of a

  shunting device according to the invention.

  Figure 2 is a longitudinal sectional view

passing through a channel of the housing.

  The device shown in the figures

  takes a housing element 1 formed of two half-shells 2 and 3 glued or welded by their edge, the half-shell 2 having an imprint 4 in which is mounted a shunt bar 5 having a series of male tabs 6 engaged in canals

  7 and each having a light 8.

  The half-shell 3 is complementary to the half-shell 2 and has a series of housings 9 each corresponding to a channel 7, each housing

with a blind hole 10.

  Each channel 7 is intended to receive a

  female electrical contact member 12 with rectan section

  gular with a core 13, two side walls 14 with extensions and folded opposite one another to form a ceiling wall 15 in which is formed an opening 16 and a strip is cut out

restraint 17.

  Each female electrical contact member 12 has tabs 20 and 21 for crimping a conductor 22 which has a colored mark 23. The half-shell 3 comprises, at the right of

each channel 7, a boss 25.

  The ends of the channels 7 opposite the impression 4 and the housings 10 are filled with a sealing gel 26 of a self-healing type, that is to say of a type capable of being crossed by a member. 12 and close around the conductor

electric 22.

  Such sealing gel is translucent

  and the half-shell 1 is transparent.

  When you put in place a

  electric tact 12, this is engaged by the

  free mite of a channel 7 through the gel 26 then is pushed so that the boss 25 comes to cooperate with the opening 16 which ensures the blocking of said member 12

  in the canal. In this position, the tongue cor-

  respondent 6 is engaged in the contact member

  12 and the retaining bar 17 is inserted

  light 8, which makes the assembly of

  organs 6 and 12 practically non-removable.

  Through the blind hole 10, one can check

  visually trust the correct position of the member 12, the mark 23 being printed at a point of the conductor

  in front of blind hole 10 if the as-

  semblage of the tongue 6 and the member 12 is correct.

  It can also be verified that the electrical connection is made by engaging, in the blind holes 10, tester tips which pass through the bottom of said holes, the gel and the insulation to bear against the conductive core. After this verification,

  gel 26 ensures, by healing, good isolation

electric tion.

  Of course, the invention is not limited to

  tee to the embodiment which has just been described

  to be present. Many modifications can be made

  detailed information without going beyond the framework

of the invention.
