Abstract
Abstract A terminal block for a cable terminal unit comprises an insulating body which has receiving apertures in which in each of which a respective clamp is inserted which consists of a terminal contact and a separation and/or clamping device. The terminal contact is formed integrally with the separation and/or clamping device and at least one guide surface is provided for a wiring tool. With this construction it is possible to employ for wiring a single-strut wiring tool such as for example a common screw driver, whereby cost savings and operational simplifications may be achieved. Moreover, the terminal block has the advantage of simple and functionally reliable construction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
Terminal block comprising: an insulating body having receiving apertures; terminal contacts arranged in the receiving apertures and having contact slots; separation and/or clamping devices integral with respective terminal contacts; at least one separation and/or clamping device and associated terminal contact form a clamp; said clamp having at least one guide surface for guiding a single-strut wiring tool; said at least one separation and/or clamping device having a shearing member protruding from said guide surface; and a stop member being arranged in an inserting direction of said wiring tool beneath said shearing member, said stop member being substantially parallel to said shearing member, said stop member being in a step-like staggered arrangment relative to said shearing member.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
39 words
Terminal block according to claim 1, wherein the stop member and the shearing member are bent from a main part of the clamp and protrude in parallel from the main part in the same direction as the terminal contact.
Claim 4
Dependent Claim
22 words
Terminal block according to claim 1, wherein the separation and/or clamping device and the terminal contact are arranged V-shaped to each other.
Claim 5
Dependent Claim
28 words
Terminal block according to claim 1, wherein on a lower side of the insulating body openings are provided for receiving a metallic connection bar or a disconnect plug.
Claim 6
Dependent Claim
37 words
Terminal block according to claim 1, wherein in the insulating body a chamber is arranged which adjoins an insert opening for the single-strut wiring tool and which is adapted in shape to the single strut wiring tool.
Claim 7
Dependent Claim
15 words
Terminal block according to claim 1, wherein the clamp is provided with a separation contact.
Claim 8
Dependent Claim
32 words
Terminal block according to claim 6, wherein the separation contact has two substantially parallel lower limbs which are adjoined upwardly in the direction of the shearing member by two substantially V-shaped limbs.
Claim 9
Dependent Claim
20 words
Terminal block according to claim 6, wherein the separation contact is integrally connected to a main part of the clamp.
Claim 10
Dependent Claim
