Definitions

  • the present invention refers to a device for coupling the contact block and the handle of an electrical connector member, such as, for example, a mobile electric plug or socket of the industrial type.
  • mobile electric plugs or sockets of the industrial type consist of two separate elements which can be connected to each other: a first element called a contact block and a second element called a handle. Inside the contact block there are disposed electrical contact elements of the male type (pins of the plug) or female (seats of the socket). An electric cable having a plurality of electric conductor wires connected to the electrical contacts disposed inside the contact block passes inside the handle.
  • the contact block and the handle must be made in two separate pieces which can be removably assembled with each other. Disassembly of the handle from the contact block must necessarily be done with the aid of a tool.
  • a coupling system is known to the art in which the handle has a protruding portion in which a seat is formed to house a flexible tongue.
  • the contact block on the other hand, has a protruding tooth in which a seat matching the flexible tongue is formed.
  • the flexible tongue bends and snaps into the seat of the protruding tooth, preventing disassembly of the two elements.
  • Such disassembly involves the use of the tip of a tool to bend the flexible tongue so as to cause uncoupling thereof from the seat of the tooth.
  • Said coupling device holds the disadvantage of having to modify the structure of the handle and the contact block excessively to provide the protruding seat and the protruding tooth, respectively. It further involves complex mechanical working to form the matching seat in the protruding tooth, hi normal use, particularly in difficult settings like building sites, workshops, carpenter's shops, etc. the part for access to the flexible tongue, being protruding, can easily become obstructed or go out of alignment (if, for example, it is dragged on the ground) and consequently no longer allow the two parts to be disassembled. As a result, said coupling system is excessively expensive, difficult to produce and uncertain in its reliability over time.
  • the object of the present invention is to overcome the drawbacks of the prior art, providing a coupling device between the contact block and the handle of an electrical connector member that is practical, inexpensive, simple to produce and is reliable in its operation over time.
  • the coupling device for a contact block and a handle of an electrical connecting member comprises an elastic member made integral with the contact block near the proximal end thereof.
  • Said elastic member has an outward protruding end part, designed to snap engage elastically inside a through hole formed near a proximal end of the handle.
  • the handle can be assembled on the contact block without the aid of any tool, whilst for disassembly it is sufficient to insert the tip of a tool into the hole of the handle to cause the elastic member to bend so as to release it from the hole.
  • Figure 1 is a perspective view, illustrating, in an exploded view, a handle, a contact block and a deformable member forming part of an electrical connector provided with the coupling device according to the invention
  • Figure 2 is a front view of the contact block of Figure 1;
  • Figure 3 is bottom plan view of the contact block of Figure 2;

  • Figure 7 is a perspective view illustrating the three elements of Figure 1 assembled but not yet in the locking position, in which a portion of the handle has been removed to make the elastic member visible
  • Figure 8 is a perspective view, like Figure 7, illustrating the three elements of Figure 1 assembled and in the locking position, in which a portion of the handle has been removed to make the elastic member visible.
  • Figure 1 illustrates the structure of an electrical connector member 1 comprising a contact block 2, an elastic member 6 and a handle 8.
  • the contact block 2 is designed to accommodate the electrical contacts of the connector 1.
  • Said electrical contacts can be in the form of male elements (pins of a plug) or female elements (seats of a socket). ).
  • the contact block 2 comprises a substantially cylindrical body, hollow on the inside, which has a distal end 23 and a proximal end 24. Retaining teeth 25 designed to retain the electrical contact assembly of the connector 1 are provided on the inside surface of the body 20, near the proximal end 24.
  • An abutment flange 21 protrudes radially outwards from the body 20 of the contact block, near the proximal end 24.
  • a seat 26 designed to receive the elastic member 6 is formed on the outer side surface of the body 20 between the abutment flange 21 and the proximal end 24.
  • the seat 26 has a substantially rectangular shape and is delimited by two longitudinal partitions 27 and 28.
  • the partition 27 has a slot 27' which opens into the seat 26 and the partition 28 has a circumferential portion 30 with a slot 30' which opens into the seat 26.
  • a rectangular protrusion is provided in the seat 26 in a central position.
  • the elastic member 6 is preferably a spring band or a leaf spring consisting of a small metal plate which has a flat rectangular portion 60 with a larger surface and a portion 61with smaller surface folded in a U shape on the portion with a larger surface 60.
  • the larger surface portion 60 has a rectangular hole 62 designed to receive the rectangular protrusion 29 of the seat 26.
  • the portion with a smaller surface 61 has an end 63 which protrudes outward forming an angle of about 90° with respect to the plane of the portion with a smaller surface 61.
  • the elastic member 6 is housed in the seat 26 of the contact block.
  • the plate with a larger surface 60 abuts against the surface of the seat 26 and its edges are retained in the slots 27' and 30'.
  • the protrusion 29 of the seat 26 engages in the hole 62 of the plate with a larger surface 60 to avoid any shifting of said plate. In this manner the plate with a smaller surface 61 protrudes outward from the seat 26 and can bend elastically, coming nearer to the plate with a larger surface 60.
  • a radial protrusion 31 is provided in the side surface of the contact block, between the abutment flange 21 and the proximal end 24, with reference to Figures 1, 2 and 3, to the right of the partition 27.

  • An external thread 83 is provided on the body 80, near the distal end 82, to receive a ring nut designed to clamp the electrical cable. Going toward the proximal end 81, the body 80 has a truncated conical transitional portion 84 increasing in diameter which ends in a proximal end portion 85 of greater diameter.
  • the outside diameter of the proximal end portion 85 is substantially equal to the outside diameter of the flange 21 of the contact block 2.
  • the inside diameter of the proximal end portion 85 is slightly greater than the outside diameter of the part of contact block body 20 between the flange 21 and the proximal end 24 of the contact block.
  • a recessed rectangular seat 87 in which the hole 86 is situated is formed in the inner side surface of the proximal end portion 85.
  • three radial protrusions 88, 89 and 90 are formed in the inner surface of the end part 85.
  • a first radial protrusion 88, a second radial protrusion 89 and a third radial protrusion 90 are provided.
