Definitions
- the invention relates to an electrical contact for a conductor connection terminal, which has an insulating housing, the contact having a connection section for connecting an electrical conductor, the connection section having a spring clamp connection with at least one clamping spring for connecting the electrical conductor by means of spring force.
- the invention also relates to a conductor terminal with at least one such electrical contact.
- Such an electrical contact is known, for example, from DE 197 35 835 A1.
- the invention is based on the object of specifying an improved electrical contact that can be used even more universally.
- a corresponding conductor connection terminal should be specified.
- the electrical conductor is fixed to the contact to an improved extent, so that the electrical conductor is also better fixed and fixed in a rigid position when the contact is still in place is not located in the insulating housing of the conductor connection terminal.
- the electrical conductor is often fixed in place by parts of the insulating material housing, for example by a conductor entry channel or similar elements. As a result, such conductor connection terminals or their contacts are not so well suited for being fitted with the electrical conductor before the contact is inserted into the insulating material housing.
- the present invention creates an electrical contact which, on the one hand, has the advantageous properties of a spring-loaded terminal connection for connecting the electrical conductor, namely simple clamping of the electrical conductor without tools, permanent, secure fixing of the electrical conductor and secure contact, as well as the possibility of releasing the electrical conductor from the spring clamp connection.
- the contact according to the invention can be used in a manner comparable to known contacts with crimp technology. In this way, a contact and, accordingly, a conductor connection terminal are created, e.g.
- the contact according to the invention is simpler and more reliable to wire due to its spring-loaded terminal connection.
- first spatial plane can, for example, be a vertical plane running parallel to the conductor insertion direction
- second spatial plane a horizontal plane running parallel to the conductor insertion direction, in each case related to an essentially open underside of the electrical contact.
- the first support points can be arranged in the connection section. Furthermore, the second support points can be arranged in the connection section.
- the at least three first bearing points in the conductor insertion direction of the electrical conductor in the spring-loaded terminal connection comprise a front first bearing point, a middle first bearing point and a rear first bearing point, with the middle first bearing point in the conductor insertion direction behind the front first Support point and is arranged in front of the rear first support point and is located on a side facing away from the front first support point and rear first support point of an inserted and connected electrical conductor. This allows a stable three-point mounting of the clamped electrical conductor.
- the electrical conductor is then held relatively rigidly in the first spatial plane, so that no or at least hardly any twisting movements of the electrical conductor in the first spatial plane relative to the contact are possible.
- the electrical conductor is thus held on one side by the middle first support point and on the opposite side by the front and rear first support point.
- the spring-loaded terminal connection has a defined clamping point for clamping the electrical conductor, the front first bearing point in the conductor insertion direction being in front of the clamping point and the rear first bearing point being behind the terminal point.
- This allows a particularly stable mounting of the electrical conductor and, accordingly, a good fixation against movements of the first spatial plane.
- the central first support point can be arranged in front of or behind the clamping point in the conductor insertion direction.
- the middle first support point has a distance from the front first support point that deviates by a maximum of 50% from the distance between the middle first support point and the rear first support point.
- the middle first support point is thus arranged approximately in the middle between the front and the rear first support point, with the advantageous effects of the mentioned three-point bearing also being at some deviation from the precise mean arrangement.
- the middle first bearing point can have a distance from the front first bearing point which deviates by a maximum of 25% or a maximum of 10% from the distance between the middle first bearing point and the rear first bearing point.
- the contact has a ramp for the electrical conductor, which runs obliquely to the conductor insertion direction, with the rear first support point being located on the ramp.
- the free end of the electrical conductor thus comes into contact with the ramp at a sufficient insertion depth and is held by the ramp.
- the insertion depth of the electrical conductor is also limited.
- the oblique arrangement of the ramp to the direction of insertion of the conductor creates great variability in the use of the electrical contact for different conductor cross-sections.
- An electrical conductor with a large cross section, for example comes into contact with the ramp at a lower insertion depth than an electrical conductor with a smaller cross section. Irrespective of the cross-section, however, the oblique arrangement of the ramp ensures that the electrical conductor comes into contact with it at least in every case, and the rear first support point thus becomes effective.
- connection section has a frame-shaped conductor insertion area through which the electrical conductor is to be inserted into the connection section, with the front first support point being located on the frame-shaped conductor insertion area.
- the contact is designed to be robust thanks to the frame-shaped conductor entry area.
- a defined conductor insertion opening is provided for the electrical conductor, which is easily recognizable by the user. In this way, incorrect operation of the electrical contact is avoided.
- the frame-shaped conductor insertion area has the additional function of providing the front first support point.
- the contact has a spring-loaded lug which protrudes from the frame-shaped conductor insertion area in the direction of the clamping point and on which the central first support point is located.
- the frame-shaped conductor insertion area has a further additional function, namely the provision of the central first support point via the strap connected to the conductor insertion area. Due to its springy property, the tab has the advantageous effect that the middle first support point can adapt to the conductor cross-section of the electrical conductor to be inserted.
- the frame-shaped conductor insertion area has two opposite first side walls, a first cover section connecting the first side walls and a first base section opposite the first cover section, the first side walls, the first base section and the first cover section having a conductor insertion opening limit.
- a robust frame construction is created, which can also be produced in one piece from a sheet metal part.
- the resilient tab can, for example, protrude from the first cover section in the direction of the clamping point.
- one or both of the first side walls each have at least one spring tongue that is free from the first base section and the first cover section and forms a clamping point for clamping an electrical conductor by means of spring force.
- an integrated clamping spring that can also be provided with a one-piece sheet metal part can be provided. If both first side walls have the spring tongue mentioned, the electrical conductor can be clamped symmetrically from both sides. A clamping edge is then located at the free ends of the spring tongues, which is preferably aligned perpendicularly to the conductor insertion direction.
- the first floor section can be formed by a single material section which is bent from a first side wall in the direction of the other first side wall.
- the first base section is formed by two material sections, each of the two material sections being bent from a first side wall in the direction of the other first side wall, with a parting line being formed between the two material sections.
- the respective material section can be bent from the respective first side wall about a bending axis that runs parallel to the conductor insertion direction. In this case, the respective material section runs on the underside of the contact. It is also advantageous to bend the respective material section from the respective side wall about a bending axis perpendicular to the conductor insertion direction. For example, before bending, the respective material section can protrude from the first side wall in a direction opposite to the conductor insertion direction. After bending, the respective material section then forms a front bottom wall on the contact
- the spring-loaded terminal connection has, as clamping springs, two spring tongues running towards one another at an angle, between the free ends of which the terminal point is formed. This allows the electrical conductor to be clamped symmetrically between the spring tongues.
- the spring tongues can have a clamping edge at the free end, which enables the electrical conductor to be clamped particularly securely.
- the contact can only have three second support points for supporting and holding the spring clamp connection. have clamped electrical conductors in the second spatial level. A second support point is then provided by one spring tongue. A support of the conductor can then be formed on the inside of a first side wall of the contact. If there are two spring tongues, they can each provide a second support point.
- the at least four second bearing points in the conductor insertion direction comprise two front second bearing points and two rear second bearing points, the front second bearing points being arranged in front of the rear second bearing points in the conductor insertion direction.
- This allows a stable four-point mounting of the clamped electrical conductor.
- the electrical conductor is then held relatively rigidly in the second spatial plane, so that no or at least hardly any twisting movements of the electrical conductor in the second spatial plane relative to the contact are possible.
- the rear second support points can be arranged behind the clamping point, for example.
- the front and rear second bearing points each form a pair of cooperating bearing points which are arranged on opposite sides of the first spatial plane.
- a respective pair of interacting support points can be arranged e.g.
- the first spatial plane can, for example, be aligned parallel to the first and/or second side walls.
- the first spatial plane can run between the spring tongues.
- the first spatial plane can form a central plane between the first and/or second side walls. When an electrical conductor is clamped on, the first and second spatial planes can run, in particular, through the central axis of the electrical conductor.
- the free ends of the spring tongues form the front, second support points. This- permits a comparatively simple mechanical construction of the electrical contact, since no further elements are required to form the front, second bearing points.
- the contact has centering bevels which are aligned obliquely to the direction of conductor insertion and are arranged in the shape of a funnel, on which the rear second bearing points are located.
- the funnel-shaped design of the centering bevels similar to what has already been explained with regard to the run-on bevel, enables electrical conductors of different cross-sections to be reliably fixed in place. An electrical conductor with a large cross-section cannot be inserted as far into the funnel-shaped arrangement of the centering slopes as it can in electrical conductors with a smaller cross-section.
- the electrical conductor rests against the centering bevels with sufficient insertion depth, regardless of the cross section, and is centered by these centering bevels and is thus held by the rear second support points.
- the centering slopes thus also limit the insertion depth of the electrical conductor, preferably together with or in combination with the ramp.
- the ramp can, for example, extend obliquely from a second cover section of the contact, which is arranged behind the first cover section of the contact in the conductor insertion direction, in the direction of the clamping point. If the second cover section is still arranged behind the centering bevels in the direction of conductor insertion, the ramp can also be arranged at least partially behind the centering bevels in the direction of conductor insertion or at least partially extend into the area of the centering bevels, i.e. overlap with the centering bevels in the direction of conductor insertion.
- the electrical conductor can be clamped to the spring-loaded terminal connection before the contact is arranged in the insulating material housing, the contact being able to be inserted into the insulating material housing by means of the clamped-on electrical conductor and relements can be fixed in the insulating material housing.
- factory wiring of the electrical contact is made possible in a manner analogous to the crimping technique.
- the individual contacts can be wired and pre-assembled outside of the insulating housing so that they can then be inserted into the insulating housing. Due to the stable mounting of the electrical conductor in the electrical contact, the electrical conductor can thus be used as an aid for inserting the arrangement into the insulating material housing.
- the contact is in the form of a plug-in contact which has a plug-in section for pluggable connection to a mating plug-in contact. This has the advantage that the contact can also be used as a plug contact in a connector.
- the electrical contact with some or all of the aforementioned elements is formed in one piece from a sheet metal part, for example by means of a stamping and bending process. This allows the contact to be manufactured simply and inexpensively.
- the mentioned spring tongues can have actuating tongues which protrude from end edges of the spring tongues directed towards the first cover section, the actuating tongues being bent out of the plane of the adjoining spring tongue section, for example adjacent to the free end of the spring tongue.
- the actuating tongues can be bent outwards, i.e. bent away from the clamping point.
- the actuating tongues form a funnel shape, which forms a receiving funnel for an actuating element.
- the object mentioned at the outset is also achieved by a conductor connection terminal with an insulating material housing and one or more electrical contacts of the type explained above, to each of which an electrical conductor is clamped.
- the contact or contacts are designed as plug contacts
- the conductor connection terminal can also be designed as a plug connector.
- the insulating material housing has an actuating opening arranged in the area of the actuating tongues, through which the spring-loaded terminal connection can be opened by means of an actuating tool. The spring tongues are moved away from each other by opening the spring-loaded terminal connection, so that a clamped-on electrical conductor can be removed without any effort.
- the electrical contact in such a way that it is already inserted into the insulating material housing when the electrical conductor is to be connected. If the electrical conductor is sufficiently rigid, this can be done by simply plugging in the electrical conductor in the conductor insertion direction. In addition, it is possible to use the actuating tool to open the clamping point through the actuating opening, so that the electrical conductor can be guided to the clamping point without any effort. In this way, less rigid electrical conductors can also be connected without any problems, eg stranded conductors.
- a method for providing a conductor terminal of the type explained above with at least one electrical conductor connected to an electrical contact of the conductor terminal with the following steps: a) providing the insulating material housing of the conductor terminal, the insulating material housing having one or more contact-receiving chambers which are each set up to accommodate an electrical contact but are not yet equipped with such an electrical contact, b) connecting an electrical conductor to an electrical contact while the electrical contact is completely outside the contact-receiving chamber or is loosely inserted therein in a pre-assembly position c) inserting the electrical contact connected to the electrical conductor through a receiving opening into the still free contact receiving chamber of the insulating material housing until the electrical contact is in e has reached an end position within the contact-receiving chamber and is fixed there, in particular latched there.
- the electrical conductor can be particularly simple and reliably connected to the electrical contact while it is at least partially still visible, ie while it is not yet fully located within the contact-receiving chamber of the insulating housing. Only after the electrical conductor has been correctly attached to the electrical contact is this completely introduced into the contact-receiving chamber and fixed there by means of the electrical conductor.
- the indefinite term “a” is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component”. If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°).
