[0001] The present invention relates to a housing for accommodating one or more conductor connection terminals formed as feedthrough connectors. The invention further relates to a set (in other words set) consisting of such a housing and one or more conductor connection terminals formed as feed-through connectors. [Background technology]

[0002] Conductor connection terminals are available in a wide variety of embodiments in the electrical field, for example as screw terminals, such as in the form of two screw terminals, or having respective spring-loaded terminals for connecting electrical conductors. Available as spring-loaded terminals. A conductor connection terminal formed as a feed-through connector is characterized by having at least two conductor terminals for connecting and electrically coupling at least two electrical conductors. Conductor insertion openings for these conductor terminals are arranged on diametrically opposite sides of the housing of the conductor connection terminals.

[0003] Conductor connection terminals are available with housings formed differently, especially with different external cross-sectional shapes, depending on the technical embodiment. Conductor connection terminals are usually not or only poorly protected against ingress of dirt and moisture. In a considerable number of use cases there is a need for increased protection, especially against moisture. For example, waterproofing according to degree of protection IP68 is required.

[0004] A housing for an electrical plug-in connection is known, for example from US Pat. No. 3,680,036. [Prior art documents] [Patent document]

[0005] [Patent document 1] U.S. Patent No. 3,680,036 [Outline of the invention] [Problems to be solved by the invention]

[0006] The object of the present invention, on the other hand, is to provide a housing for accommodating one or more conductor terminals which are designed as feed-through connectors. Furthermore, a set composed of them is presented. [Means for solving the problem]

[0007] The task is to accommodate one or more conductor connection terminals formed as feed-through connectors, as follows: a) the housing has a tubular central receptacle, which is formed closed in the circumferential direction (in other words, on the circumference), and from the first end face of the receptacle, having at least one continuous opening extending to a second end face opposite the first end face of the container; b) the continuous opening has, in its axially central region, at least one inner cross-sectional contour adapted to the outer contours of a predetermined number of conductor connection terminals having a predetermined outer cross-sectional shape to be accommodated in this continuous opening; death, c) the housing has a first thread on the first end face and a second thread on the second end face, d) the housing has a first threaded cap with a threaded portion that allows the first screwed cap to be screwed onto the first threaded portion of the first end face of the container; e) the housing has a second screw cap with a threaded part, which allows the second screw cap to be screwed onto the second threaded part of the second end face of the container; is solved by a housing having the characteristics of

[0008] The present invention has the advantage that it presents a housing for accommodating one or more conductor connection terminals in the form of feed-through connectors, which is easily available and assemblable by the user. The housing can be formed from relatively few parts, thereby facilitating simple construction and easy assembly. In addition, the enclosure is suitable for implementing a simple and secure sealing concept that prevents misuse by the user.

[0009] Advantageously, the housing has a tubular central receptacle which is formed closed in the circumferential direction. This ensures an excellent shielding action against ambient influences for the conductor terminals arranged in the housing or in the opening of the central receptacle. This continuous opening ensures that the conductor connection terminals can be easily accommodated and / or attached to the receptacle. The receptacle can be formed completely or partially cylindrical on the outside, but can also have other cross-sectional shapes on the outside.

[0010] Advantageously, the receptacle body has an inner cross-sectional contour which, in its inner opening, is adapted to the outer contour of the conductor connection terminal to be received therein. This also facilitates easy assembly by the user. Furthermore, conductor connection terminals arranged in continuous openings can be reliably held and protected against vibration loads.

[0011] A simple assembly of the parts of the housing is additionally facilitated in that the first and second screw caps can be connected with the central receptacle by means of a screw connection. This allows easy and intuitive assembly of the housing. In one advantageous form of the present invention, the first screw cap and / or the second screw cap each have a through hole for passing an electric cable, and the conductor (core wire) of this electric cable is It is coupled with a conductor connecting terminal located inside the body.

[0012] In this way a novel and particularly advantageous encapsulation for feedthrough connectors is provided. According to an advantageous embodiment of the invention, provision is made for the first threaded part and / or the second threaded part to be designed as an external thread. This also facilitates easy and intuitive assembly of the components of the housing. In addition, this allows the screw connection to have relatively large dimensions and a correspondingly high strength. For example, the first screw cap and / or the second screw cap may be formed in the form of a sleeve nut. Within the screw cap, a strain relief for the electrical cable threaded through the through hole of the screw cap can also advantageously be formed or arranged by a clamping element, for example with a clamping plate.

[0013] The receptacle may be formed from one or more parts, for example in the form of a single injection-molded part or multiple injection-molded parts. According to an advantageous embodiment of the invention, provision is made for the receptacle with the inner cross-sectional contour to be formed in one piece. This has the advantage that the assembly of the parts of the housing is particularly simple for the user, and that the insertion of the conductor connection terminal through the given inner cross-sectional contour is also particularly simple and ergonomic. It has become.

[0014] According to one advantageous form of the invention, it is provided that the continuous opening has an axially constant inner cross-sectional profile. In this way, the conductor connection terminal to be fitted into the opening can be properly guided by the inner cross-sectional contour at the very beginning of the fitting process.

[0015] According to one advantageous form of the invention, it is provided that the inner cross-sectional contour of the continuous opening has a star shape. This optimizes the space utilization of the interior space of the container. The star shape also forms a longitudinal piece inside the opening that further increases the strength or stiffness of the container.

[0016] According to an advantageous form of the invention, the housing has a first seal, which is adapted by tightening the threaded connection of the first screw cap of the first end face to the first screw. The lid can be pressed against the housing and / or the housing has a second seal, the second seal by tightening the threaded connection of the second screw lid on the second end face to secure the second lid. It is contemplated that the screw cap can be pressed onto the receptacle. This allows a reliable sealing of the enclosure, which ensures that the ingress of moisture into the interior space of the enclosure is avoided. In addition to this, pressing on the first seal or the second seal makes it possible to expand them radially a little, so that a positive seal against the cables passed through can also be achieved. The first seal and / or the second seal can be designed as ring-shaped seals. The first seal and / or the second seal may be formed with inner openings aligned rotationally symmetrically with the continuous opening of the container.

[0017] According to an advantageous embodiment of the invention, the first seal and / or the second seal have, in axial cross-section, a profile with radial branches and axial branches projecting therefrom. , it is contemplated that the radial branches extend primarily in the radial direction of the container and the axial branches extend primarily in the axial direction of the container. In this way, the first seal or the second seal can seal well both the interface between the respective screw cap and the container, as well as the cables passed through. In this case, a radial branch of each seal can be pressed against the receptacle by a respective screw cap. In this case, the axial branches may abut closely against the outer surface of the cable that is passed through the seal. The seal thus has, in other words, an L-shaped cross-sectional shape.

[0018] Advantageously, the first seal and / or the second seal may consist of an elastic material, for example an elastomer such as rubber or silicone. According to an advantageous form of the invention, the housing consists only of a central receptacle, a first screw cap, a second screw cap, a first seal and a second seal. is intended. With such a five-part construction, the housing can be provided inexpensively and easily assembled by the user. Additionally high mechanical robustness can be achieved.

[0019] According to one advantageous form of the invention, provision is made for the receptacle to have a single continuous opening. This allows a particularly simple and ergonomic fitting of the conductor connection terminal into the continuous opening.

[0020] According to an advantageous embodiment of the invention, the first screw cap and / or the second screw cap has undulations, rectangular contours and / or hexagonal contours on at least one region of its outer surface. It is contemplated to have This has the advantage that the first screw cap or the second screw cap can be easily rotated by the user about the longitudinal axis, and the screw connection can be made by hand, without tools, or It can be securely tightened with a tool, for example a wrench. For this purpose, the receptacle can also advantageously have contours for mounting tools on its outer circumference, for example in the form of at least two mutually facing flats, so that the support when tightening the screw cap is provided. can be guaranteed.

[0021] The object mentioned at the outset is furthermore a set consisting of a housing of the type described above and one or more conductor connection terminals formed as feed-through connectors, wherein the conductor connection terminal or the conductor connection terminals The conductor connection terminal is solved by a set that can be accommodated in a continuous opening of the receptacle in a form-fitting manner. This may also realize the advantages discussed above. Due to the form-fitting accommodation of a conductor connection terminal or of a plurality of conductor connection terminals, these conductor connection terminals can be held in a defined place, in particular with little radial play, and are therefore not subject to vibration loads. However, it cannot excessively collide with the inner wall of the container.

[0022] According to an advantageous aspect of the invention, it is provided that the one or more conductor connection terminals each have a spring-loaded terminal (in other words a spring clamp terminal) for connecting the conductors. In this way, the conductor can be connected to the conductor connection terminal particularly simply by the user, often without tools. Spring-loaded terminals also ensure long-lasting, reliable contact. Such spring-loaded terminals may, for example, have clamping springs for which, depending on the style, additional busbars may be present. To actuate the clamping spring, the conductor connection terminal can have an actuating element, for example a pivotable actuating lever.

[0023] In the sense of the present invention, the indefinite concept "one" should not be understood as a number. So, for example, when we say one component, this should be interpreted in the sense of "at least one component". If the angular expression is in degrees, the angular expression is to a 360 degree (360°) circle scale.
