Definitions

the invention relates to an insulation displacement contact with two spaced apart oppositely arranged, spring-like clamping legs, each one have free end portion, the free end portions toward each other are angled and a slot for contacting and clamping hold of an electrical wire.
the invention further relates to an electrical Connection device for connecting at least two electrical wires, which has two such insulation displacement contacts.
a generic insulation displacement contact is known from EP 0 247 360 B1, where the slot for holding a wire is elongated over the length of one profiled portion of a conductive part is formed, which in this area has a hollow polygonal cross section.
an insulation displacement contact to be used advantageously must of course also be inexpensive to manufacture, which is both the choice of materials and a Form production taking into account mass production concerns.
the object of the invention is therefore an insulation displacement contact and an electrical connection device with two such insulation displacement contacts to provide, which are compared to the prior art by advantages in use with regard to improved clamping and contact ability as well as particularly cheap Award manufacturability.
the cutting-clamping element according to the invention thereby enables a defined setting or presetting of elasticity and spring properties and thus the cutting, clamping and holding properties, wherein the constructional design, which is improved compared to the prior art, also enables material to be saved.
Advantageous configurations of the insulation displacement contact according to the invention are described in the subclaims.
the object of the invention is achieved in that two insulation displacement contacts according to the invention in a conductive connection in one Housing are held.
FIGS. 7 to 9 e.g. terminal block
an insulation displacement contact designated as a whole by 1
adjacent side walls are angled Sections connected to each other, and one of the side walls is angled by overlapping lugs 3a and 5a of the adjacent side walls 3 and 5 educated.
the entire insulation displacement contact 1 is preferably by punching and Bending a sheet metal blank produced, the overlapping approaches 3a, 5a to increase the dimensional stability of the four side walls 2, 3, 4 and 5 existing base body connected positively and non-positively are punched 7 into the parts 3a, 5a with a suitable tool are.
another connection technique could also be used such as spot welding.
FIGS. 1 to 5 are in extension of the wider side walls 3 and 5 clamping legs 10, 11 are provided, the free end portions 12 and 13 angled and define a straight-line slot 15, the opposing, sharp side edges of the free end sections 12 and 13 for contacting, i.e. Cutting the insulation, and for clamping an inserted one serve electrical wire.
the slot 15 can one of its end portions can be wedge-shaped to insert a wire to facilitate.
the angled, free end sections 12 and 13 of the clamping legs are not directly opposite, as is clearly shown in particular in FIGS. 1 and 4, but in the direction of extension the clamping leg are arranged offset from each other, where-by the effect is achieved that a straight line (i.e. in one to the side walls 3 and 5 parallel orientation) wire inserted in the area of the slot slightly is angled and thereby a modified clamping effect occurs.
the improved clamping and contact effect of the insulation displacement contact according to the invention results from the fact that the clamping legs 10 and 11 against the known embodiment according to the prior art not by one of them Foot section connecting foot points are held, but in one piece by extension of the side walls 3 and 5 of a basic body which is rectangular in cross section are formed.
the side walls 3 and 5 form due to the one-piece construction together with the side walls 2 and 4 a comparatively rigid Structure so that the spring properties of the clamping legs 10 and 11 practical are determined solely by their dimensions, in this example by the dimensions b (width) and l (length) indicated in FIG. 2.
the sidewalls 3 and 5 take part in one due to the side walls 2 and 4 connecting them Deformation only very little.
Fig. 6 shows the structure of a connection element designated as a whole with 17 two insulation displacement contacts 1, 1 'according to the invention, for installation in a electrical connection device such as a terminal block provided is.
the connection element 17 consists of two mirror-symmetrically opposite one another arranged insulation displacement contacts, which - as already in Fig. 1st to 5 indicated - by a U-shaped angled, elongated conductor 16 are interconnected. 6 clearly shows that both the middle conductor 16 as well as both insulation displacement contacts 1, 1 'from a common, punched Sheet metal blanks are produced by folding, the side wall approaches 3a, 5a or 3a ', 5a' are each connected by stamping to one another as possible to create a rigid connection.
FIG. 7 to 9 show in different views an electrical connection device, in which a connecting element 17 in a preferably made of plastic Housing 20 is held.
a connecting element 17 in a preferably made of plastic Housing 20 is held.
In rectangular recesses 21, 21 'of the housing 20 slide-like connecting tools 23, 23 'are slidably received.
Each Connection tool is with a passage opening 25 or 25 'for receiving a connecting wire and with an actuating opening 26 or 26 'for insertion a lever or rod-like actuating instrument for longitudinal displacement of the connecting tool, wherein the actuating instrument into a recess 28, 28 'is to be carried out in the housing 20.
connection tool 7 and 8 each show the connection tool in the right part of the illustration 23 'in a position in which the through opening 25' is in the actuating direction seen in front of the slot 15 'of the insulation displacement contact 1', so that a too Contacting wire inserted through the opening 25 'and the connecting tool 23 'by means of a through the opening 26' into the recess serving as an abutment 28 'to be inserted, for example a screwdriver, can be moved by pivoting movement to the center of the housing 20, so that the position of the connecting tool shown on the left in FIGS. 7 and 8 23 results.
the connecting tool 23 or 23 ' a profiled section 29 or 29 ', the cross section of which is complementary to the hollow cross section of the remaining between the clamping legs 10, 11 Intermediate space is designed so that one introduced through the passage opening 25 or 25 ' Wire is inserted securely into the slot 15. Furthermore and the same
the connection tool with a second section 30 serves the purpose or 30 ', which is arranged at a distance from the first section 29 or 29' is around the free end sections 12, 13 of the clamping legs forming the slot to record in between.
a web connecting these and passing through the slot can be arranged. This ensures that even relatively flexible wires are safe and without excessive deformation can be moved into the slot.
Insulation displacement contact which here consists of two interlocking interlocking Share is divided. This measure reduces the manufacturing and tooling costs even further, since the base body does not have to be made in one piece and bends or Bends are easier to manufacture.
FIG. 10 shows a perspective, exploded view of two parts 40, 40 ' one as a whole designated 17, the parts in this Case are identical to each other, while Fig. 11 shows different views of an individual Parts 40 and 40 'respectively show and FIG. 12 corresponding views of a connection element 17 shows in the assembled state.
Fig. 10 From Fig. 10 it can be seen that the two parts 40, 40 'by punching and folding are made from two sheet metal sections, with a particular advantage
the split version shows that at no point does a bend of more than 90 ° is necessary because the closed cross section of the respective base body Insulation displacement contacts 1 only in the assembled state (FIG. 12) by interaction of the two parts and their side wall sections 2, 2 'and 3a, 5a' or 5a, 3a 'is formed (Fig. 10).
the two parts 40, 40 ' are positively locked to several Set, the two parts initially from the one shown in Fig. 10, spaced Position brought into a contiguous position, which the after Fig. 12 corresponds, but with both parts still offset in the longitudinal direction are, as indicated in Fig. 10.
this starting position are the Side wall sections 2 ', 3a' on the side wall sections 2 and 5a facing Sides of the side wall sections 3a and 2.
Foot folds 42, 42 ' are opposite one another at the same height in the longitudinal direction opposite. Locking tabs 44, 44 'engage in corresponding recesses 46, 46' of the side wall sections 3a, 3a '.
