Description

the F i g. 1 to 3, a product manufactured from sheet-shaped, resilient contact material U-shaped connecting element 1 which is formed by a single contact spring which is provided at its free leg la with a slotted guide 1 b, while the other leg side 1 c at the bottom of the recess 2a of the insulating material holder 2 is attached and connected to a contact element 3, not shown in detail in the drawing, for an incoming wire conductor.

Further includes a slider existing made of insulating material 4, which is provided on a longitudinal side with a run-on slope Aa and at the end in a detent-like projection 4 b passes to the terminal connection.

The production of the clamping connection between the insulated wire 5 and the connection element 1 happens as follows:

The wire 5 is in the insulated state from above material existing approximately spiral connection element Γ is composed of an outer part la and an inner part Ib ' , which with the part la', for example by spot welding, a component

The particular to make contact with the conductor to be connected 5 slot guide Ua and 11 b is located "at each of the free leg ends lie or life 'of the connecting element 1'. The Anscnluß-

element 1 'is at its lower part with a contact element 3 firmly connected to connect an incoming wire. The contact element 3 can z. B. be a contact pin (Fig. 4).

An off still belongs to the clamp connection

> 5 Insulating material existing sleeve body 2 ', which is provided with a recess which receives the connecting element Γ after the connection Jung has been made; 2 α . The production of the clamping connection between the insulated wire 5 and the connecting element I.

at the enlarged slot opening 1 d in the wire 20 happens as follows:

insertion slot 1 b of the connection element 1 in a contact arrangement not shown in detail

the contact element 3 is fixed to the connecting element 1 and the sleeve body 2 '. The Hulsenkorper takes the position shown in dashed lines in FIG. 4. The connection element Γ is included

plugged. Then, for preparing the Kontakiverbindung the slider 4 is with its detent-like projection 4 b behind a corresponding latching projection 1 e of the connection element 1 in the recess 2 "of the insulation mount 2 inserted and pushed into an end position. Here, the latching protrusion Ic runs of the connecting element along the inclined contact surface 4a of the slide 4 so that the b provided with the slot guide 1 free leg 1 α b in the guide gap 2 of the insulation mount 2 occurs and the wire 5 b einpreßt in the slot. 1 Since the width of the slot guide 1 b is smaller than the thickness of the metallic core 5a of the wire 5 is, for contacting the Drahtisolatiou is cut, and the Sch'.itzkanten penetrate the metal core of the wire a.

After the contact connection has been established, the slide 4 remains in the insulating material holder 2 (FIG. 2).

The second embodiment (FIGS. 4 and 5) shows a functionally similar terminal connection As according to FIGS. 1 to 3. In this embodiment, the terminal connection is used to produce the terminal connection instead of the clamping slide a springy? Connection element to be pushed Sleeve body. ■ used.

springs. In the insulated state, the wire S is inserted from above into the wire insertion slots 11a '"and ti b'" of the slot guides Ua ', Ub' of the connection element 1 '. Then to produce the

Contact connection of the sleeve body 2 'guided by the contact pin 3 pushed upwards over the connection element Γ, the spring-loaded connection element compressing and the free leg ends Wa ", Ub" and 11 c in a horizontal position

Move direction. The inserted wire 5 is pressed into the slots 11a 'and Wb' with the support of the free leg end 11c serving as a counterhold.

Since the width of the slot guides 11a 'or 11b'

is smaller than the thickness of the metallic core 5a of the wire 5, the wire insulation is used to take the contact cut through, and the slot edges penetrate the metallic core of the wire.

The sleeve body 2 'is with locking projections 2 ft'

or 2c ', in which the free leg ends 11a "and after making the contact connection Click into place on the connection element Γ.

Claims (3)

Claims: isolated and clamped. Connect with a 1. Detachable electrical terminal connection further contact element is not provided. After manure, in which the wire to be connected axially in the latter is given the opportunity to connect two conductors a slot of a leaf-shaped, resilient, from parallel by pressing both of them into a slot contact material existing connection element 5, so that the risk of a Schlecheingeschitzt and results in it by pressure by means of a th contact. This solder- and screw-free clamp body, cutting through the wire clamp connection technology, has so far required spatial insulation and is clamped in place, thereby allowing the connection element (1 or ßenden conductor to be inserted transversely to the connection element V) in the area of the slot (16 or 11a ', 116') η ren and in this position on the connection element Festzuquer bent to the axial direction and clamped with a. In addition, the application of this technology, which is approximately axial up to the connected wire (S), is not satisfactory when it comes to a contact element (3) for an incoming exact compliance with the line symmetry. Wire is firmly connected. The invention is therefore based on the object 2.
