Definitions

  • the present invention relates to an insulation displacement connection type connector for electrical insulation displacement connection of cables (wires, leads, etc.) inserted into an insulation displacement block with insulation displacement portions of terminals housed in a terminal block, and also relates to an insulation displacement process (or procedure) thereof .
  • KOKAI Japanese Unexamined Utility Model Publication
  • No. 6-88054 has proposed a structure wherein a pressure welding block and a terminal block are formed by separate members, respectively, and the pressure welding block can be held in a position parallel to the terminal block prior to pressure welding.
  • an insulation displacement connection type connector including: a terminal block for housing therein a plurality of terminals to which cables are insulation displaced for electric conduction; an insulation displacement block having cable insertion holes for inserting cables, said insulation displacement block being adapted to be set in a state parallel to said terminal block at a time of insulation displacement of cables and to be moved, as it is, close to said terminal block, in a translational movement manner; inclination holding means for releasably holding said insulation displacement block in a state inclined relative to said terminal block, to thereby facilitate insertion of said cables; and parallelism holding means for releasably holding, upon releasing of said holding, said insulation displacement block in a state parallel to said terminal block.
  • the present invention also provides a method for insulation displacement in an insulation displacement connection type connector, including: a terminal block for housing therein a plurality of terminals to which cables are insulation displaced for electric conduction; and an insulation displacement block having cable insertion holes for inserting cables, the insulation displacement block being adapted to be set in a state parallel to the terminal block at a time of insulation displacement of cables and to be moved, as it is, close to the terminal block, in a translational movement manner; comprising the steps of: holding the insulation displacement block in a state inclined relative to the terminal block, making use of inclination holding means; inserting cables into cable insertion holes of the insulation displacement block; holding the insulation displacement block in a state parallel to the terminal block, making use of parallelism holding means; and conducting an insulation displacement operation by moving the insulation displacement block relatively close to the terminal block, in a translational movement manner.
  • FIGs. 1 to 3 show respectively a plan view, a left side view and a right side view of an embodiment of an insulation displacement connection type connector according to the present invention.
  • a connector 1 shown in the drawings is basically composed of two separate members, i.e., a terminal block 3 which constitutes a main body of the connector 1 and an insulation displacement block 5 detachably attached to the terminal block 3.
  • the terminal block 3 is molded of polyamide resin (nylon 6, nylon 66, etc.), PBT (polybutylene terephthalate) , or PCT (polychlorinated triphenyl) , etc. by injection molding.
  • the insulation displacement block 5 is molded of, for example, transparent PC (polycarbonate) by injection molding, so that cables can be seen therethrough upon insulation displacement connection. Additionally, a transparent material or opaque (translucent) material, for example, PP, polyamide resin, PET (polyethylene terephthalate), etc., can be used.
  • a box- shaped recess 7 On one side (left side in Fig. 1) of the terminal block 3 (connector 1) , is provided a box- shaped recess 7 in which a plurality of terminals 9 (4 terminals in the illustrated embodiment) are provided and secured at a predetermined space (shown in Fig. 2) to be connected to corresponding connectors (not shown) .
  • a largely cut away recess 11 is provided on the other side (right side in Figs. 1 and 4) of the terminal block 3.
  • the recess 11 defines a portion to which the insulation displacement block 5 is detachably attached.
  • terminals 9 are arranged and secured in parallel, with raised root portions being upwardly bent by a predetermined length.
  • the raised portion of each terminal 9 is in the form of a fork (or U-shape) i.e., is shaped in a so- called insulation displacement form.
  • the (bifurcated) insulation displacement portions 13 of the terminals function to cut outer sheaths of cables (assuming that the cables are individually separated cables in the illustrated embodiment) to directly establish and keep the electrical connection to the cables.
  • the raised portions of the terminals 9 are staggered considering the space utilization efficiency. Namely, if the raised portions were laterally arranged along a line, the lateral size of the connector could be too small to accommodate all the raised portions.
  • the insulation displacement block 5 mounted to the recess 11 of the terminal block 3, as shown in Fig. 5 which shows a single insulation displacement block 5, is provided on its rear surface with cables inserting circular through holes 15 which are regularly arranged in parallel, and whose number corresponds to that of the terminals 9 (i.e., 4 through holes in the illustrated embodiment) .
  • the circular holes 15 are connected to each other at the lower portions thereof on the inlet side.
  • a cable engaging member (engaging mean) 21 for temporarily holding the cables inserted in the circular holes 15 to prevent the cables from being disengaged therefrom is mounted to the connecting portion of the circular holes 15.
  • the cable engaging member 21 can be integrally formed with the insulation displacement block, but is formed as a separate piece (part) in the illustrated example, and is, for example, molded of the same material as the aforementioned terminal block 3 by injection molding. As shown in Fig. 8, the cable engaging member 21 is provided with elastically deformable abutments 21b which extend obliquely from base portions 21a in the form of a cantilever. The number of the abutments 21b corresponds to that of the circular holes 15 (i.e., four) .
  • Each of the abutments 21b extends in the corresponding circular hole when the cable engaging member 21 is mounted to the insulation displacement block 5 (Fig. 7) .
  • Projections 21c are provided on the lower surface portion of the cable engaging member 21. The projections 21c are engaged in corresponding recesses 25 provided in the insulation displacement block 5 to prevent the cable engaging member 21 from being easily detached therefrom.
  • the insulation displacement block 5 is provided on each of the opposed side faces thereof with four projections.
  • the first front and lower projections 31 (on the terminal block connector connection side) are loosely engaged in larger rectangular first recesses 33 provided on the inner side faces (of both sides) of the terminal block 3 when the insulation displacement block 5 is mounted to the terminal block 3, namely, the loose engagement permits the first projections and the first recesses to relatively move to some extent.
  • the engagement portions define a hinge portion at which the insulation displacement block 5 can move relative to the terminal block 3.
  • the second projections 35 ride over the upper edge portion of the terminal block 3 and enter the guide groove 37 so as not to prevent the movement of the insulation displacement block 5 to a parallel position (described below) .
  • the second projections 35 and the guide grooves 37 in which the projections 35 are inserted serve as a guide means for the downward translation (parallel movement) of the block 5.
  • the guide means could be practically ineffective in view of the slight (translational) displacement (i.e., the guide means is not necessarily indispensable) .
  • the third front and upper projections 41 (on the connector connection side of the terminal block 3) and the fourth rear and upper projections 43 (on the cable insertion side) which are both provided on the upper portions of both side faces of the insulation displacement block 5, and between the first projections 31 and the second projections 35 are constructed so that when the insulation displacement block 5 is moved to the parallel position, the third and fourth projections ride over the inner upper edge portions of the terminal block 3 to establish and keep the parallel state .
  • the third projections 41 and the fourth projections 43 are fitted in the corresponding recesses, i.e., first recesses 33 and second recesses 45, respectively, upon the pressure welding connection in which the insulation displacement block 5 is engaged in the terminal block 3. Consequently, the third and fourth projections are engaged by the upper portions of the recesses 33 and 45 to prevent the insulation displacement block 5 from being detached.
  • the insulation displacement block 3 Before the cables be connected are inserted in the insulation displacement block 5, the insulation displacement block 3 can be easily brought to and held in an inclined position (by 30° - 40°) relative to the terminal block 3. Therefore, the inserting cable operation can be extremely easily carried out (Fig. 9) .
  • the cables Upon insertion of cables, the cables are mechanically plugged into the circular holes 15 of the insulation displacement block 5 until the cables abut against the terminal block 3. Therefore, further insertion of the cables extending through the insulation displacement block 5 is not permitted. Owing to this and to the transparency of the insulation displacement block 5, it can be easily recognized and confirmed whether the amount of the cable insertion amount is sufficient or not. Therefore, not only can the burden on an operator be reduced, but also misoperation can be eliminated.
  • the cable engaging member 21 in the insulation displacement block 5 engages with each cable and prevents the cables from being slipped-off, thus resulting in an extremely enhanced operability.
  • the cable holding force (more than about 5g/Pin) was considerably larger than that (Og/Pin) in the absence of the cable engaging member. This value satisfies the requirements (equal to or more than 3g/Pin) .
  • the insulation displacement portion 13 of the terminal 9 is insulation-displaced and connected to the cables, i.e., the insulation displacement portion 13 of the terminal 9 cuts the outer sheaths of the cables and establish and maintain an electrical connection with the cables.
  • the third projections 41 and the fourth projections 43 of the insulation displacement block 5 are fitted in the recesses (first recesses 33 and second recesses 45) provided on both inner surfaces of the terminal block to establish a slip-off prevention state (structure) .
  • FIG. 1 is a plan view of an embodiment of an insulation displacement connection type connector according to the present invention.
