Definitions

  • the invention relates to an arrangement for securing screws of electrical terminals comprising a body or a housing-like element made of insulating deformable material, preferably a plastic material in which a substantially vertically extending shaft is formed, in which a screw including its head is inserted retractable, wherein for securing the recessed screw in the shaft wall a profiling is provided which is elastically deformable when inserting the screw and here when passing the head, the profiling to secure the screw back to the shaft interior deformed after sweeping the head.
  • Screwdriver opening is covered, wherein ribs are formed in the cover, which have a minimum distance from each other, which is smaller than the diameter of the screw head.
  • the protrusion of the ribs during the rotary movement of the screw head is removed by scraping, so that these ribs are pushed away by deformations.
  • the ribs are deformed back again, so that there is a backup of the sunk screw in the housing area.
  • G 93 08 096.4 One type of captive screw is known from G 93 08 096.4.
  • the screw-side connecting part of the housing has an integrally formed material ring, which presses in the screwed state of the screw in the unthreaded or the tapered region, so that the screw is secured against unintentional loosening of the connecting part.
  • the arrangement relates to a screw lock of electrical connection terminals, wherein the screw is arranged in a shaft of a body or box-like element retractable.
  • a profiling is provided in the vertical shaft, which can be deformed elastically when inserting the screw and here when sweeping the head. After sweeping the profiling, the profiling deforms back so that it deforms back onto the head of the screw so as to secure the countersunk screw.
  • the invention thus presents the problem of providing a particularly simple and efficient arrangement for securing screws, which in particular allows larger head tolerances.
  • the shaft wall is provided with a fully or partially encircling molded rear handle, which cooperates with a formed in the material circumferential trench or space, either the screw and / or the shaft can take a non-circular shape. It is particularly advantageous here that the head of the screw has an oval shape. Accordingly, of course, it can also be provided that the shaft for receiving the screw here can take an oval shape.
  • the shaft stands for the
  • Screw largely free and thin-walled.
  • the dimension of the largest width is greater than the maximum screw head.
  • the roof overhang is significantly smaller than the smallest screw head.
  • the perimeter of the hole is always larger than the head.
  • the hole circumference is always larger than the screw head circumference, the hole edge does not have to be stretched, as in the known solution.
  • the assembly is very simple and screw tolerances are less problematic than in the known solutions.
  • the same principle can also be realized with a round hole and a non-circular oval screw.
  • the largest head circumference of the screw must be smaller than the circumference of the hole.
  • the hole wall stretches and adapts to the non-round screw head shape without being stretched.
  • the screw head In this insertion of the screw has the support that the molded rear handle is annular, whose cross-sectional shape is trapezoidal here. If, therefore, the screw head is sunk in the shaft, the screw head in its non-circular shape initially strikes the upper obliquely set flank, which in particular favors the deflection of the annular rear grip in the region of the trench, the screw head, as the screw head continues to be screwed in such that the cross-sectional shape, here the trapezoidal shape, sweeps over, so that then a deformation takes place through the lower inclined edge.
  • the circumferential trench or clearance has a rectangular shape, wherein the bottom of the trench is here below the neck of the lower inclined edge of the molded-in rear grip.
  • FIG. 1 shows a plan view of an arrangement for
  • Screw lock wherein two shafts are shown in plan view with recessed Phillips screws with oval head;
  • Figure 2 is a sectional side view and perspective view of Figure 1 of a countersunk screw with an oval head in a shaft.
  • Figure 3 shows a further embodiment of the invention, wherein here in plan view two shafts are shown in oval shape with recessed slot screws; and
  • Figure 4 is a sectional side view and perspective view of Figure 3 a sunk slotted screw in an oval designed shaft.
  • Figures 1 to 4 each show arrangements for securing screws from terminals.
  • the arrangement comprises a body or a housing-like element 1, which consists of insulating deformable material, such as a plastic material.
  • a vertically extending shaft 2 is formed, in which a screw 3 including its head 4 is inserted retractable, as is apparent in particular in Figures 2 and 4.
  • a profiling 6 can be provided in the region of the shaft wall 5 according to the first embodiment, FIGS.
  • the profiling 6 is designed such that when sweeping the screw head 4, ie when screwing, the profiling 6 is elastically deformable. Thus, if the screw head 4 sunk in the shaft 2, the profiling 6 is pushed back, whereby it deforms back to the shaft interior after passing through the screw head 4 again.
  • the shaft wall 5 cooperates with a circumferential trench 8 formed in the material, wherein the screw 3 or the shaft 2 can assume a non-circular shape.
  • a franking or a free space may be provided.
  • the screw head 4 take an oval shape, as shown in Figures 1 and 2, wherein after another Embodiment, shown in Figures 3 and 4, the shaft 2 for receiving the screw 3 occupies an oval shape, in particular, this oval shape is given by injection molding.
  • the integrally formed rear handle 7 is formed annularly such that its cross-sectional shape is trapezoidal. It goes without saying that, when the screw head 4 is sunk with its connected shaft 9, the lower edge of the screw head 4 first comes to the upper inclined surface 10 of the rear handle 7, and further rotation due to the inclination of the rear handle 7 in the material weakening is pushed away for digging 8, wherein then after passing through the screw head 4 of the rear handle 7 deforms back into the interior of the shaft. This results in a quasi spring-mounted rear grip 7 as a result of the molded-in trench 8, which causes a material weakening, in particular in the region of the circumferential rear grip 7, which promotes this resilient deformability of the rear grip 7.
  • the shaft 2 is designed oval. This results in a backup by two opposite surfaces. Elastic deformation of the shaft 2 is ensured by the circumferential trench 8 and thereby reduced wall. The screw 3 is held by the housing transition.
  • screws and shaft may also have similar circumferential dimensions.
  • the surfaces are deformed in the shaft 2 and these briefly assume a circle-like shape.
  • the material deforms for the most part in the elastic region of the plastic and only slightly in the plastic range.
  • the rear handle 7 is largely retained during assembly and removal from the injection mold.
  • the circumferential trench 8 has a rectangular shape, wherein the bottom 11 of the trench 8 lies below the projection of the lower inclined flank 12 of the molded-in rear grip 7.

Abstract

L'invention concerne un dispositif de sécurisation de vis de bornes de connexion électriques, comportant un corps ou un élément (1) en forme de boîtier réalisé en matériau isolant déformable, de préférence en matériau plastique, dans lequel un puits vertical (2) est formé, une vis (3) et sa tête (4) pouvant être insérées dans ledit puits. Pour la sécurisation de la vis insérée (3), un profilage (6) est prévu dans la paroi du puits (5), celui-ci se déformant élastiquement lors de l'insertion de la vis (3), au moment du passage de la tête (4). Pour la sécurisation de la vis (3), le profilage (6) se redéforme vers l'intérieur du puits après passage de la tête (4). Selon l'invention, la paroi du puits (5) est pourvue d'une rainure périphérique (8) formée dans le matériau, la vis (3) ou le puits (2) adoptant une forme non-ronde.
