Socket strip for LEDs or plugs

The invention relates to a socket strip for accommodating light-emitting diodes or plugs.

Since it has been found that LEDs are suitable for the use of SMO technology due to the heat stress of reflow soldering, it is desirable to have socket strips available, especially for front panel installation, which can optionally be fitted with standard LEDs and are suitable for reflow soldering. It would also be advantageous if plugs could be used instead of LEDs, so that they can function as test or switching sockets.

The object of the invention is therefore to create a socket strip for accommodating LEDs and plugs, which is suitable for reflow soldering and can be optionally equipped with LEDs or plugs.

This object is achieved in that the socket strip consists of one or more socket bodies, each of which has at least one recess for receiving a light-emitting diode, from which one or two passages for receiving the connection contacts of the light-emitting diode extend through the socket body and open into two chambers on the side opposite the recess, in each of which a contact connection is arranged in the form of a rounded spring element pre-tensioned into the passage, which has an extension leading out of the socket body adjacent to its base, which is designed as an SHD solder connection.

Further embodiments of the invention can be found in the following description and the dependent claims.

The invention is described below with reference to the figures shown in the accompanying

illustrated embodiments are explained in more detail.

Fig. 2 shows a section through a socket body of the socket strip from Fig. 1.

Fig. 3 shows a cross-section of a socket body with a test plug inserted.

Fig. 5 shows a top view and a side view of an arrangement of contact connections for the socket strip.

Fig. 6 shows a usable embodiment of a plug-in indicator light.

Fig. 7 shows a perspective view of another embodiment of a socket strip, which is equipped with light-emitting diodes.

Fig. 8 shows a socket body of the embodiment of the socket strip from Fig. 7 in section with a short-circuit plug.

The socket strip 1 shown in Fig. 1, which is preferably injection-molded from plastic, comprises a plurality of socket bodies 3 which are connected to one another via predetermined breaking points 2 and which are preferably cube-shaped and have a square cross-section. The predetermined breaking points 2 enable the socket strip 1 to be supplied in a specific length and shortened to a desired strip length depending on the use, whereby individual socket bodies 3 can also be separated, which then represent a cost-effective version of a single socket.

The socket bodies 3 shown in Fig. 1 and 2 each have a circular recess 4 on their front and top sides, each of which is suitable for accommodating a light-emitting diode 5. From the recesses 4, which are preferably arranged in the middle, leadthroughs 6 extend into the socket body 3 perpendicular to the front or top of the socket body 3. The leadthroughs

6 end in front of the rear or bottom side of the socket body 3 and cross each other in such a way that alternatively the assembly can only be carried out from the front or from above.

Approximately in the lower rear quarter of the body of the bush 3 there are two chambers

7 are arranged adjacent to one another in the longitudinal direction of the socket strip 1, each of which accommodates a contact connection 8. The bushings 6 are located in the chambers 7. A contact connection 8 is always arranged in the area of a chamber 7.

&igr; t _te 5 · * * * *

arranged and rounded spring element designed in such a way that the connection 9 of a light-emitting diode 5 inserted into the bushings must be inserted against the spring pressure of the contact connection 8 and thus a good contact is achieved, i.e. the contact connection 8 designed as a spring element is spring-loaded against the two crossing bushings 6. The spring element of the contact connection 8 is designed as a shaped spring, e.g. as an open ring and is provided with an extension 10 which is led out of the socket body 3 at the back adjacent to the base and forms a solder connection suitable for the 3w technology.

It is advisable to provide a mold separation 11 horizontally in the middle of the socket bodies 3 to accommodate the bushings 6, the chambers 7 and the contact connections 8, i.e. to manufacture them in halves. The contact connections 8 are then clamped between the shell halves and led out of the socket bodies 3.

The two connections 9 of a light-emitting diode 5 contact the two contact connections 8 of the corresponding socket body 3 when inserted from the front or from above.

The socket bodies 3 can have spacers 12 on their underside towards a circuit board 13, onto which the extensions 10 of the contact connections 8 are soldered using SMD technology.

The contact connections 8 are expediently manufactured as contact combs (Fig. 5), whereby the contact connection 14 for the individual contact connections 8 is separated after assembly.

After being plugged together, the shell halves of the socket bodies 3 are connected by gluing, molding or the like in such a way that it is ensured that the contact connections 8 are firmly seated in the socket body 3 and the feedthrough points for the extensions 10 of the contact connections 8 are sealed.

The socket strip 1 can be used both to accommodate light-emitting diodes S, whose connections 9 must have a corresponding length so that they can be accommodated by the bushings 6, and to accommodate test plugs 15 or short-circuit plugs 16, as shown in Fig. 3 and 4 respectively. According to Fig. 3, a plug pin 17 made of metal is inserted into the bushing 6 and contacts the contact connection 8, whereby the plug pin 17 is adapted to the cross-section of the bushing β. The test plug 15 can be provided with an opening t& through which an electrical conductor 19 can be inserted, which is connected to the test plug 15 by a

a connection 20 is connected*^.

The short-circuit bar 21 shown in Fig. 4 is provided with a knurled part 22 and is adapted on both its legs to the diameter of the bushing 6 and can be inserted into two bushings 6 of two adjacent socket bodies 3.

According to Fig. 6, the short-circuit breaker 16 can also be designed in such a way that it has two connecting pins 23 which are connected to one another via a control lamp 24, the control lamp 24 possibly being integrated with a resistor 85 at the same time in the handle part 22.

In order to achieve additional strength on the circuit board 13, especially when using test plugs 15 and short-circuit plugs 15, additional soldering tongues 26 suitable for SMO technology can be attached adjacent to the bottom side of the socket body 3 in the area of the socket body 3 facing away from the extensions 10 of the contact connections 8, i.e. preferably soldering tongues 26 protruding towards the front of the socket body 3 and/or fastening pins 27 on the underside of the socket body 3. The soldering tongues 26 only serve to stabilize and not to make contact.

In the embodiment shown in Fig. 7 and 8, a denser arrangement of the light-emitting diodes 5 is achieved in that the recesses 4 are each directed only towards the top of the socket body 3, while the two chambers 7 for receiving the contact connections 8 are arranged on both sides of the bushing 6 in the lower area of the socket body 3. An inserted light-emitting diode 5 therefore contacts a contact connection 8 with its connections 9 in the bushing 6. The resulting arrangement of the extensions 10 of the contact connections 8 on both sides is particularly advantageous for the use of SMD technology. This arrangement enables a particularly dense sequence in the arrangement of the light-emitting diodes 5, which can be arranged with a diameter of, for example, 2 mm in a grid of, for example, 2.54 mm.

Particularly in this embodiment according to Fig. 7, but also in the above embodiments, instead of one feedthrough 6, which could for example be oval or dumbbell-shaped in section or the like, which accommodates the two connections 9 of a light-emitting diode 5, two feedthroughs 6 can be provided for each connection 9 of the light-emitting diode 5. In this case, one of the two feedthroughs 6 extending from the recess 4 then opens into one of the two chambers 7.

According to Fig. 8, particularly flat short-circuit plugs tS can also be used, the short-circuiting brackets 21 of which contact both contact points 8 and thus bridge them.
