摘要:
A termination strip (1) for a telecommunications module comprising at least one pair of contact elements (50) arranged side-by-side, each terminating in contacts (13) on opposed longitudinal sides (9, 10) of the strip for connection to a wire pair of a telecommunications cable. Each contact element comprises: (i) two end regions (52) that terminate in contacts on respective longitudinal sides of the termination strip and are substantially aligned with one another along the longitudinal axis of the contact element, and (ii) a narrower central region (51) between the end regions, located substantially on one side of the longitudinal axis. One of the end regions comprises a resilient contact region (53) extending from the end region substantially on the other side of the longitudinal axis and engageable by an external component inserted into the termination strip from one of the opposed longitudinal sides. The contact elements are substantially identical but turned through 180° relative to one another with the narrower central regions adjacent one another.

A telecommunications module comprises a termination strip (1) having two rows of contacts (13) along a first side (9) of the strip and two rows of contacts along an opposed second side (10) of the strip, and a mounting mechanism (15) at each end of the strip by which the strip is removably-mounted on a carrier (3) with a selected one of the first and second sides (9, 10) accessible for making connections to contacts on that side. At least one of the mounting mechanisms (15) is engageable in an opening (11A, 46) in the carrier whereby the strip can be mounted on the carrier in one orientation only with the first side (9) accessible, and in only one orientation with the second side (10) accessible.

摘要:
A functional module in the field of telecommunications has a front, a rear and four side faces, more than two first contacts and more than two second contacts, each first contact being connected with a second contact, the contacts being adapted to be connected with first and second contacts of at least one contact module. Contacts are adapted to connect wires therewith so as to establish electrical connection between the contacts of the functional module and the contacts of the contact module. In addition, a telecommunications module includes at least one functional module and at least one contact module. An assembly of two or more telecommunications modules and a kit of parts are described. A method of installing a telecommunications module include installing a contact module then fitting a functional module to the contact module.

A telecommunications overvoltage protection magazine (10) permits in the mounting position direct mounting in a telecommunications rack-mounting system behind a junction zone (12) for cable conductors and electrical connection to the junction zone (12), the surge arresters being insertable in a mounting position from below, from above or partly from above and partly from below, more particularly alternatingly from above and below.
摘要:
A terminal block assembly is provided containing a bus bar having a knife edge arranged to penetrate the insulation of an insulated conductor that is carried by a support member, whereby during the connection of the support member with the terminal block, the insulation is penetrated by the knife edge to electrically connect the conductor with the bus bar. In order to facilitate the connection of the support member to the terminal block, the support member and the terminal block are provided with openings that cooperate to define a long-arm pivotal leverage arrangement that provides an assembling tool with a mechanical advantage for assisting in the penetration of the insulation by the knife edge.
摘要:
A telecommunications module has a housing with an interior and an exterior and plural contact elements (12, 40) extending from the interior to the exterior so as to enable the connection of exterior wires and/or the connection of interior or exterior electrical components and/or enable the tapping of contacts of another telecommunications module, wherein at last two of the contact elements (12, 14) are mutually connected within the interior of the housing by an internal wire (28, 32, 40, 42).
摘要:
An assembly of a telecommunications module and at least one protection plug containing at least one protection component is characterized in that also the module itself contains at least one protection component.
摘要:
A connection contact in a single piece has two insulation displacement contacts (14) having each an insulation displacement slot (16), a contact and guiding surface (20) and a shearing element. The connection contact further has two contact legs (22, 23) one end of which is connected to an insulation displacement contact (14), a home contact formed between the free ends of the contact legs and a section (27) that links the insulation displacement contacts (14). The disclosed connection contact in a single piece is characterized in that the linking section (27) is designed as a substantially U-shaped loop (28). As lead-shearing element, an insulation displacement contact (14) is associated to each leg (30) of the U- or V-shaped loop (28), so that the contact pressure between the contact legs of the home contact can be easily adjusted as desired. A fatigue-proof home contact is thus obtained, which is also economical to produce.
摘要:
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.
