Description

CONNECTION DEVICE FOR COAXIAL CABLE5
TECHNICAL FIELD
The invention relates to a connection device for connecting a coaxial cable t a component arranged on a circuit board, of the type having one edge provide with rows of connecting pins which coact with connection blocks containin female contacts on one side and connection pins associated with these on th other side.
BACKGROUND ART
Relatively expensive arrangements are necessary for connecting a coaxial cable to a component on a circuit board of the type mentioned, since such a cable cannot be connected quite simply to the connection pins on the edge of the board, it being necessary to replace the pins with coaxial connection sleeves in which the pin of the coaxial connector can be inserted.
DISCLOSURE OF INVENTION
The invention enables a coaxial cable to be connected to a component mounted on a circuit board, while using the customary connection pins.
The invention is characterized by the disclosures in the claims.
BRIEF DESCRIPTION OF DRAWING
The invention is explained in detail below with the aid of an embodiment, while referring to the appended drawing, on which Figure 1 schematically illustrates in perspective a connection device in accordance with the inven¬ tion, Figure 2 being a side view and Figure 3 a plan view of the connection device.
MODE FOR CARRYING OUT THE INVENTION
Figure 1 illustrates the inventive connection device in perspective. A coa ji
OM cable denoted by 1 is to be connected to a component 3 mounted on a circuit board 2. Along its edge portion the board 2 is provided with contact blocks 4, of which one is shown lifted up in relation to the circuit board, for the sake of clarity. The block 4 is provided along one side with rows of bent pins 15, which are soldered to the circuit board and via printed conductors 31, 32, 33, for example^are connected to the different components. Along its other side the block 4 is provided with straight pins 14, which are fixed in rows of holes in the same way as the pins 15, for engagement with a connection block 5 having female contacts 6. In the extension of the female contacts the connection block 5 Is provided with connection pins 7, forming rows in the same way as the other pins in block 4.
The coaxial cable 1, which is to be connected to the connection block 5, has a cylindrical screening sleeve 8 connected to its outer conductor and having an outer diameter such that" it can be inserted between four pins 7a-7d on the block 5. The sleeve 8 is provided with four slits 12 which are shorter than the pins 7. In assembling, the central conductor 1 is first soldered to the central pin 9, subsequent to which the sleeve 8 is thrust in between the pins 7a-7d such that these engage in the slits. Since the pins are pointed, they are pressed outwards as the sleeve is pressed down, so that the sleeve is kept" in a fixed position by engagement between the pins and the edges of the slits. There has thus been" obtained a removable coaxial connection from the cable 1 to the component 3.
Figures 2 and 3 respectively show, in front and plan views, the inventive coaxial connection before, and after, the sleeve has been thrust in between the pins. The inner contour of the pins lies along a circle having a somewhat smaller diameter than that of the sleeve. When the sleeve is pressed down, the pins 7 glide in the slits 12 until they come into contact with the end wall of the slits, and since the ends of the pins are bevelled off, the pins glide obliquely outwards along the outer wall of the sleeve, as will be seen from the right-hand portion of Figure 2. Further to the elastic retention, it is also possible to solder the pins to the wall of the sleeve 8, as indicated by 16 in Figure 2.
It will be seen that by the invention there has been obtained a much simpler
OM connection device than the previously used devices, when existing standard connection devices having screening sleeves provided with longitudinal slits have been used. ■

Claims

{ C L A I M S
j 1 Connection device for connecting a coaxial cable (1) to a component (2) arranged on a circuit board (3) of the type having one edge provided with rows of connection pins (14), which coact with connection blocks (5) having female contacts (6) on one side and connection pins (7) associated with said female 5 contacts along the other side, characterized in that four pins (7a-7d) are placed in the connection block (5) such that a screening sleeve (8) of a coaxial cable can be thrust between them, and in that a pin (9) centrally positioned in relation to said four pins is adapted for soldering to the central conductor (11) of the coaxial cable, the sleeve (8) being provided with longitudinal slits (12), -10 which are approximately just as wide as the thickness of the pins but shorter than the pins, so that when the sleeve is thrust between these pins it comes into engagement with the walls of the slits for retaining the sleeve (8).
2 Connection device as claimed in claim 1, characterized in that said four connection pins (7a-7d) surround a circle, the diameter of which is somewhat less than the outer diameter of the screening sleeve, so that when the sleeve is thrust down the pins glide in the slits until the end portions of the pins come
5 against the end walls of the slits and are deflected outwardly.
3 Connection device "as claimed in claim 1 or 2, characterized in that the screening sleeve is connected to the pins by welding or soldering.
