摘要:
An electric box (3) for electric components such as data outlets, telephone points, outlets, and switches, is shaped as a mainly prismatic, open box with at least one locking device (14) placed at each of two opposite side walls (11), the locking device (14) is arranged in such a way that it allows the electric box to be led into a cable channel (1) between two opposite flanges (8) along a front opening (2) in this when said side walls are oriented towards the longitudinal direction of the channel, and can be engaged with the flanges when the electric box is in place inside the channel. The engagement of the locking device (14) with the flanges takes place by means of at least one knife (25) on the locking device (14) with at least one cutting edge (33). Thereby, the electric box can be wedged tight on the opposite flanges along the front opening in a cable channel with a stronger joining than known before.

A tension relief member (2) for a cable junction box to secure a lead-in cable (1) comprises a gripper part (4-6), a stop device and a resilient blocking device (7). The gripper part (4-6) has resilient locking parts (5, 6) by means of which the tension relief member (2) may be secured releasably to the cable junction box in connection with an opening in it. The clamping device allows movement of the cable (1) in one direction into the cable box. The blocking device (7) offers resistance to the cable when it has been moved a distance into the cable lead-in passage.

An electrical circuit board and a multiconnector having protruding contact pins, which together form contact areas for providing contact with a complementary connector, are arranged such that the contact pins (6-13) extend out from one of the sides of the circuit board (1) substantially in a direction K which corresponds to the direction of coupling of a multiconnector and a complementary connector.

An electrical distributor board for receiving electrical components (6, 7, 8), each of which is provided with electrical coupling means (15), is normally standardized, which, with the present standards, would not leave sufficient space for establishing a main distribution frame comprising signal conductors (16, 17). In the main distribution frame board according to the invention, the electrical coupling means (15) are arranged at such a distance from the lid (5, is not shown in fig. 2) that there is nevertheless room for the connection conductors (16, 17).

摘要:
A piercing terminal system for a flat cable (20) having a plurality of conductors (12) and plurality of piercing members (13), each having two legs (14a, 14b) enclosing a slot (15) which may receive a conductor (12), and provided with locking means (16) which may receive and retain the legs (14a, 14b) clamped about a conductor (12). According to the invention, each piercing member (13) is provided with a locking means also acting as a terminal means (16) which may be intended to abut the upper and/or lower face of the flat cable and provided with a slot (17), into which the legs (14a, 14b) of the piercing member (13) may be pressed. Consequently, a highly flexible electrical connection system is provided with a stable conducting connection between the cable conductor (12) and the terminal (16).
摘要:
A modular system for cover frames to be mounted about adjoining boxes for mains switches and mains outlets. The manufacture of combination frames is avoided by using a rectangular cover frame dimensioned to enclose a box for a mains switch or a mains outlet. The cover frame is provided with opposing outer edge portions, forming at least one bar which may be separated from the rest of the cover frame. In addition to rendering the use of special combination frames superfluous when several closely interspaced switches and outlet are needed, the described cover frame comply with several national, European standard specifications as well as market related specifications.
摘要:
The basic switch module according to the invention makes it possible to construct a multipole electrical motor circuit breaker comprising a circuit breaker base (12), arranged to accommodate several basic switch modules (30), an operating mechanism (25), a top section (46), and a handle on a square shaft. The same basic switch modules may be used for several different types of circuit breaker, whereby the estimated number of switch modules to be produced by the manufacture is so large that the modules may be made highly automated production.
摘要:
An electricity distribution board having a distribution terminal block which supplies a place of consumption. The distribution terminal block has 3 terminals of which the first terminal receives voltage from a main supply. By means of a contact part, which may short-circuit the first and second terminals, the supply voltage may be fed to the electricity meter, which is integrated in the electricity distribution board, and from there to the place of consumption. The third terminal of the distribution terminal block may provide a short-circuit between the first and third terminals when disconnection between the first and second terminals is established. Power may hereby be fed to the place of consumption when the electricity meter is rendered inoperative, just as the power supplier has the possibility of disconnecting or connecting the voltage supply in a simple manner. The distribution terminal block is constructed as a housing with a sealable cover. The housing and the cover are made of plastics. The housing may be fixed to the electricity distribution board, which can contain the electricity meter in its interior.
