Abstract
For an electrical connector for assembly on printed-circuit boards, having a housing which contains and screens contact elements it is provided that the housing is manufactured as an injection-moulded part with integrally formed pins. When the connector is assembled on the printed-circuit board, the pins engage into plated holes and the electrical connection of the housing to the printed-circuit board is effected by soldering the pins or by means of a press-in portion formed on the pins.
Description
` 1 21 80489 Electrical connector The invention relates to an electrical connector for assembly on printed-circuit boards, having a single- or multi-part housing which contains and o screens contact elements of the connector, and having means of connectingthe housing in an ele.,~ "y conductive manner to the printed-circuit board.
Such co,~,~eulu, ~, particularly when they are provided with coaxial contacts, have to have a screen in order to prevent extemal disturbing pulses from reaching the contact elements inside the u~ eulol and to prevent outward emission of pulses which are carried through the contact elements.
It is known to provide electrical w, " ,e,.lu~ ~ with a conductive housing, which contains the contact elements and is used to retain and screen said contact elements. The contact elements comprise solder pins or press-in pins, which project from one side of the housing and are insertable into holes of a printed-circuit board. For the electrically conductive cu""eulioll of the housing to the printed-circuit board, a sheet metal part is provided which is fastened (riveted) to the housing and uu~ Jrises pins which are insertable into plated holes of the printed-circuit board. In said case, however, manu-facture of another component in addition to the housing is required.
The object of the invention is to construct an electrical co",~lu, of the type described initially in such a way that it may be manufactured inexpensively.
_ .
Said object is achieved in that the housing takes the form of an injection-moulded part and is electrically conductive, and that pins integrally formed on the side of the housing ~acing the printed-circuit board are provided, 2 1 $0489 which are insertable into holes of the printed-circuit board and connectable to printed conductors of the printed-circuit board.
Advantageous, tri~lel1 le~ of the inYention are indicated in claims 2 to 5.
The advantages achieved by the invention are in particular that, by virtue of integrally forming the solder or press-in pins on the housing preferably manufactured as an injection-moulded part, there is no need for an addi-tional cu" ,~ e"~ for e ,ld~l;sl li~)g the electrical connection of the housing to o the printed-circuit board. In said respect, a further advantage is that contact-ing problems (contact resistance of co,~,~e~iol1 points) between the connec-tion of the additional c~",pu,)e"l to the housing are also eliminated.
A further advantage, given the use of a high-purity zinc casting alloy as a housing material, is that said material has an excellent electric conductivity and so a reduction of the electrical housing It:si~la~ is achieved.
An embodiment of the invention is illustrated in the drawings and described below in detail.
The drawings show:
Fig. 1 a view of a connector, Fig. 2 the side view of the connector according to Fig. 1, and Fig. 3 the bottom view of the connector according to Fig. 1.
The connector illustrated in Figs. 1 to 3 substantially comprises a housing 1, in which contact elements 2 are held. The contact elements take the form of coaxial contacts and, at the left side of the connector, tubular screening sleeves 3 are disposed over the contact elements and fastened conductively in or to the housing. Projecting from the underside 4, i.e. from the side of the 2 1 804~9 housin3 directed towards the printed-circuit board, are terminals 5 of the contact elements. Said terminals are provided with a press-in portion 6 which may be pressed into holes of a printed-circuit board which is not shown in detail here.
s The housing 1 of the connector is preferably made of a high-purity zinccasting alloy such as, for example, GD-ZnAi4Cu1 according to DIN 1743, Part 2, and comprises two half shells 7, 8. The contact elements 2 are held in said housing by means of spacers made of insulating material, which are ~o not shown in detail here. The housing or the half shells are manufactured as injection-moulded parts and are provided at the underside with integrally fonmed pins 9. The pins, which during assembly of the ~or,,~e~ul on the printed-circuit board engage into plated holes, take the form of solder or press-in pins, the press-in pins being provided with a press-in portion 10.
The press-in portion may comprise a rigid or, optionally, elastic press-in zone.
The housing or the half shells may optionally be made of plastic material and provided with a conductive coating - metallic coating.
Such co,~,~eulu, ~, particularly when they are provided with coaxial contacts, have to have a screen in order to prevent extemal disturbing pulses from reaching the contact elements inside the u~ eulol and to prevent outward emission of pulses which are carried through the contact elements.
