Description

Modular housing system

description

The invention is based on a modular housing outlet system according to the preamble of the independent claim 1.

Such housing outlets are needed to carry signals and currents from housings. These can be a variety of housings or devices that are to be provided with a connection.

Depending on the housing and application case different requirements are given for housing outlets. So there are housings on which a connector is provided as a housing outlet. A mating connector can be connected to the housing via the connector and signals and currents can be routed out of the housing.

Depending on the type of housing, the signals and currents, as well as the application, different types of connectors are used. Whether high-pole or low-pole connectors, circular connectors or rectangular connectors, with screw cap, bayonet catch or snap-in lock, depends on the respective application, the housing or even the user's ideas.

From DE 10 2014 1 10 095 A1 a modular housing outlet system is known. This serves to lead out electronic signals by means of electrical contacts. The electrical contact is received in a housing outlet spigot. The housing outlet spigot is variable, wherein the terminal is uniform on a circuit board arranged in the housing. In EP 0 685 909 A2 a connector is disclosed, which consists of a plug-in housing with an integrated circuit board and a connector pins having plug. The plug and the plug-in housing have mutually complementary positioning elements. Due to the positioning elements results during the insertion process, a defined position of the connector pins on the circuit board.

DE 20 2015 001 968 U1 discloses an interface diagnostic module for vehicles. The module allows data exchange of different protocol without variation of contacts or connections. It also allows effective mechanical coupling between the male and female connectors, with the position of the contacts on a socket of the connector being final.

In another application, a cable is led out of the housing, which serves as a housing outlet. The cable is connected in the housing with other components and is guided through the housing wall. As a rule, a seal is present on the bushing in order to prevent the penetration of environmental influences.

However, the known from the prior art solutions for housing outlets have disadvantages that arise essentially from the inflexibility of the outlets. Depending on the application, the entire housing must be prepared and configured differently.

The passage of a cable through the housing wall requires a different housing outlet, as a connector which is installed in the housing wall. Depending on the size of a connector used, the opening in the housing must be dimensioned differently and it must be provided different fastening means.

In addition, different connection options are to be provided within the housing for each type of housing outlet, whether connectors or cables. For example, different components in the housing must be installed and stored for different housing outlets.

On the thus located in the housing 1 end face of the housing connection side 4.1, the electrical contacts 5 can be seen. These protrude with their press-in 5.1 into the interior of the housing. 1

An inventive housing outlet system is shown in FIG. This consists of a housing 1 as already shown in the previous figures and a printed circuit board 3 accommodated therein. At the front region of the housing 1, the outlet opening 1 .1 for receiving a housing outlet nozzle 4 is provided.

FIG. 5 also shows a series of four differently shaped housing outlet stubs 4, 4 ', 4 ", 4"'. All variants of the housing outlet stubs 4, 4 ', 4 ", 4"' have the identical housing connection side 4.1. This can be absorbed and latched in the outlet opening 1 .1 of the housing 1.

The cable outlet sides 4.2, 4.2 ', 4.2 ", 4.3"', however, are designed differently. The cable outlet side 4.2 is intended for a four-pin screw connector. The cable outlet side 4.2 'is also provided for a screw connector, but with a larger diameter and five poles. Self-threaded connector can be attached to the cable outlet side 4.2 ", but this is angled and rotatably provided on the housing outlet connection 4 ".A cable 6 is directly connected to the housing outlet connection 4"'in the cable outlet region 4.2 "' and cast with the housing outlet connection 4"'.

In order to facilitate a simple contacting of the press-in areas 5.1 of the different housing outlet stubs 4, 4 ', 4 ", 4", the multiplicity of press-in zones 3.1 are provided on the printed circuit board 3. These are arranged on the printed circuit board 3 that, depending on the housing outlet nozzle 4, 4 ', 4 ", 4"' other press-in 3.1 are contacted by press-in 5.1. By way of example, two possible contacts of press-in zones 3.1 by press-in areas 5.1 are shown in FIGS. 6a and 6b.

6a shows the circuit board 3 with the contacted housing outlet connection 4. The circuit board 3 has nine press-in zones 3.1 which are provided for electrical contacting and are arranged in three rows each three press-in zones 3.1. The housing outlet nozzle 4 accommodates four electrical contacts 5. The four press-in areas 5.1 of the electrical contacts 5 contact the press-in zones 3.1, which are located at the top, bottom, right and left in the middle. The press-in zones 3.1 in the corners, as well as the central press-in zone 3.1 remain free in this housing outlet nozzle 4.

In the figure 6b printed circuit board 3 is contacted with the housing outlet nozzle 4 '. Since this, as already described in Figure 6, has five electrical contacts 5, other press-in zones 3.1 of the printed circuit board 3 must be contacted. In this case, the press-in zones 3.1 in the corners and the centric press-in zone 3.1 are contacted by press-in areas 5.1 of the electrical contacts 5.

Thus, depending on the design, size and number of contacts different press-in zones 3.1 can be contacted on the circuit board 3. The mo- The modular housing outlet system thus offers particularly high flexibility and a large number of connection variants.

FIGS. 7a, 7b and 7c each show a separated electrical contact 5. The electrical contact 5 consists of a press-fit contact 5.1 and a connection side 5.2. The connection side 5.2 is designed for contacting a further contact element as a pin contact. In further embodiments, however, this can also be designed as a socket contact or for direct contacting of an electrical cable.

The press-in contact 5.1 of the electrical contact 5 is designed as a so-called needle-eye contact. According to the invention, the press-fit contact 5.1 is not formed axially symmetrical to the connection side 5.2. The press-in contact 5.1 has an offset x to the axis of the contact 5. By this offset x, it is possible depending on the axial orientation of the electrical contact 5 to position the press-in contact 5.1 different. As a result, different contact and occupancy patterns on a printed circuit board 3 are possible.

Such a printed circuit board 3 is shown isolated in the figure 8. In this case, the printed circuit board 3 ten Einpresszonen 3.1, which represent only five different contacts (1 to 5). The contacts 1, 2, 3 are each 2 times, the contact 4 3 times and the contact 5 only 1 times. This allows the contacting of different housing outlet nozzle 4 with different contact numbers and positions. By different axial alignment of the contacts so the different positions of the contacts (1 to 5) can be contacted on the circuit board.

9a, 9b and 9c show three different housing outlets 4, 4 ', 4 "from two views each, in the upper area in each case with a view of the connection sides 5.2 of the contacts 5; Area in each case with regard to the press-fit contacts 5.1.

Good to see are the different mating faces and pin assignments in the upper area. By appropriate axial alignment of the electrical contacts 5 in the housing outlet nozzle 4, 4 ', 4 "are generated by the offset x contact pattern of the press-fit 5.1, which differ from the patterns of the connection pages 5.2.

As a result of this different axial orientation of the contacts 5 in conjunction with the hole patterns on the printed circuit board 3, different housing outlet nozzles 4, 4 ', 4 "can be contacted on a printed circuit board 3.

This is shown again in FIGS. 10a, 10b, 10c. 9a, 9b, 9c respectively, depending on which housing outlet stub 4, 4 ', 4 "is arranged on the printed circuit board 3, different press-in zones 3 are contacted with press-fit contacts 5.1 ,

In FIG. 10a, there are three press-fit contacts 5.1, four press-fit contacts 5.1 in FIG. 10b and five press-fit contacts 5.1 in FIG. 10c.

A further embodiment provides for permanently contacting the press-in zones 3.1 of the circuit board 3 and realizing the variable interface to the housing outlet connection 4 with a pin-socket contacting of the electrical contacts 5. For this purpose, the contacts 5 are divided into two parts into a connection part 5a and a press-in part 5b.

The connection part 5a has the connection side 5.2 of the contact 5 and the press-in part 5b via the press-fit contact 5.1. The adapter module 7 has the same number of press-in parts 5b as the printed circuit board 3 via press-in zones 3.1. The press-in parts 5b are received axially differently aligned in the adapter module 7, so that form the various positions for contacting the connecting parts 5 a on the adapter module 7 by the offset x of the press-fit contact 5.1 on the press-in part 5 b.

FIGS. 11a and 11b show such an adapter module 7 mounted on a printed circuit board 3 from two views.

An isolated adapter module 7 is shown again in FIGS. 12a and 12b from two views. Recognizable sin the Einpressteile 5b, which on one side of the adapter module 7 (Figure 12a) form a different pattern, as the press-fit 5.1 on the second side of the adapter module 7 (Figure 12b). The different patterns are caused by the offset x of the press-fit contact 5.1 to the press-in part 5b.

FIG. 13 shows an adapter module 7, mounted on a printed circuit board 3 with a connected outlet branch 4, in a sectional view. The terminal part 5a of the electrical contact 5 is connected to the press-in part 5b. The press-in part 5b in turn is contacted by the offset x with its press-in contact 5.1 in the printed circuit board 3.

An electrical contact 5, consisting of the connection part 5a and the press-in part 5b is shown in isolation in FIGS. 14a and 14b. The press-in part 5b has the offset x, which is responsible for the generation of the different contact patterns on the adapter module x. The connection part 5a is designed only as a symmetrical contact, which is inserted into the different housing outlet stubs 4, 4 ', 4 ", 4". Such a housing outlet connection 4 is shown in FIG. In this exemplary embodiment, the housing outlet stub 4 has five connection parts 5a.

Different versions of housing outlet stubs 4, 4 ', 4 ", 4"' are shown once again in FIG. 16. The housing outlet stubs 4, 4 ', 4 ", 4 "'can be formed as a straight connector (4, 4'), angled connector (4") or directly connected cable (4 "') Numbers of contacts 5 and contact assignments and according to the invention are still all compatible with the adapter module 7 and the press-inserted therein 5b.
