Technical Field
The invention relates to a receptacle contact assembly, a receptacle contact and a plug contact assembly.
Background
Receptacle contacts have applications in many areas. For example, they are used for transmitting electrical signals and are equipped to receive plug contacts. The receptacle contacts are typically disposed in a housing.
The problem of the invention is to provide a solution which enables a more secure connection between the housing and the receptacle contacts.
Disclosure of Invention
According to the invention, this problem is solved by a receptacle contact assembly comprising a housing and receptacle contacts with a receptacle into which plug contacts can be inserted in a plugging direction, wherein the receptacle contacts and the receptacle are configured to be able to be widened in at least one height direction transverse to the plugging direction, wherein the receptacle contact assembly has a press-fit assembly with which, after widening, a press-fit is established between the housing and the receptacle contacts.
Receptacle contacts according to the present invention are configured for use with receptacle contact assemblies according to the present invention.
The plug contact assembly according to the invention comprises a receptacle contact according to the invention and/or a receptacle contact assembly according to the invention, and a plug contact.
The connection between the housing and the receptacle contacts is made more secure by the press-fit formed after widening. In particular, the plug contact assembly may be more resistant to vibration.
The solution according to the invention can be further improved by the following further developments and configurations, which are each advantageous per se and can be combined with one another as required.
In order to achieve a simple attachment and a simple release, the press-fit assembly cannot establish a press-fit in the non-widened state.
The receptacle contact assembly may have a first form-fitting assembly with which, in the non-widened state, a form-fit is established between the housing and the receptacle contacts in order to obtain a secure connection.
The receptacle contact assembly may have a second positive fit assembly with which a positive fit is established between the housing and the receptacle contacts after widening.
The second formfitting assembly may comprise part of a press-fit assembly. Furthermore, the press-fit assembly may comprise part of a second positive-fit assembly. The element then has a dual function, and the receptacle contact assembly can be particularly compact.
In order to achieve a simple attachment and a simple release, the second formfitting assembly cannot establish a form fit in the non-widened state.
The press-fit component and/or the second form-fit component may be enabled by widening. In the case of a transition from the non-widened state to the widened state, corresponding press-fit elements on the housing and on the receptacle contacts can interact with one another and establish a press-fit. In the case of a transition from the non-widened state to the widened state, corresponding form-fitting elements on the housing and on the receptacle contacts can engage one another and establish a form fit. In particular, this may occur automatically.
The receptacle contacts may have upper and lower sides which are opposed to each other in the height direction and, when widened, have a larger spacing from each other than in the non-widened state. The height between the upper side and the lower side can be increased by widening. In particular, the height can also be increased by the insertion of the plug contacts.
In an embodiment that is easy to manufacture, the press-fit assembly and/or the second positive-fit assembly may include a protrusion on the receptacle contact.
Alternatively or additionally, in the case of a press-fit assembly and/or a second positive-fit assembly, the projection may be present on the housing.
In an advantageous configuration, the projections may be integral with the upper and lower sides of the receptacle contact. This may simplify operation and/or manufacture.
If the projections are formed by stamping, the projections can be produced by simple process steps. For example, it may be stamped out of and/or form part of the upper or lower side.
In order to achieve a secure contact, the projection can comprise a spring portion which generates a spring force acting in the height direction.
In particular, the spring portion may comprise a spring arm. Such a configuration can be produced particularly simply and provides well-defined parameters for the spring force.
In particular, the free ends of the spring arms can be directed transversely to the plugging direction, so that a compact arrangement can be achieved. The spring arm can extend transversely to the plugging direction.
In an advantageous configuration, the spring portion may comprise two spring arms directed towards each other. This arrangement is robust and simple to manufacture.
In another configuration, the projections may be rigid. This can achieve a firm connection establishment.
The first and/or second positive fit can act in the plugging direction and/or counter to the plugging direction. The corresponding form-fitting element can prevent a movement in the plugging direction and/or counter to the plugging direction. The form-fitting element can be, in particular, a stop.
Alternatively or additionally, the first and/or second positive fit may act in a transverse direction, wherein the transverse direction is inclined, in particular perpendicular to the plugging direction and/or the height direction. This can further improve the fastness.
In an advantageous configuration, the force-less state may be a widened state. This may ensure that the receptacle contacts automatically establish engagement with the housing, for example, if no force is applied.
Alternatively, the non-widened state may be achieved by applying a force. For example, the receptacle contacts may be compressed by a user or machine. In this compressed and non-widened state, the receptacle contacts can be introduced into the housing in a simple manner. If the application of force is then reduced, a form fit between the receptacle contact and the housing can be automatically obtained.
The plug contacts may widen the receptacle contacts in the height direction. The receptacle contacts can first be switched to the widened state by the plug contacts. If no plug contacts have been introduced, the receptacle contacts cannot be widened yet. In particular, the non-widened state may be a force-free state, and in the non-widened state, there has not been any form-and/or press-fit between the housing and the receptacle contacts.
Alternatively, the force-free state may already be a widened state, and the receptacle contacts may be further widened by plugging together with the plug contacts. Then, by introducing the plug contact, the form-fit and/or press-fit already present in the first widened state can be further improved.
In order to further improve the connection and in particular the vibration behavior, the projection can be jammed with the housing in the height direction in the widened state. In the non-widened state, there is no clamping.
In a structurally simple arrangement, the receptacle contacts can be clamped in the widened state together with the housing on a clamping surface which is located on the outer end of the projection. This may be the outer end with respect to the height direction.
In another configuration, the press-fit assembly and/or the second formfitting assembly may comprise a recess. For example, the recess may be arranged on the housing. Alternatively, the recess may be arranged on the receptacle contact.
The widening of the receptacle contacts can be synchronized with the widening of the socket, for example when plug contacts are introduced.
The receptacle contact can comprise spring means for generating a contact normal force on the plug contact, wherein the spring means are formed at least by a portion of the base body surrounding the contact element, so that widening can be carried out in a simple manner.
In particular, at least one side wall of the base body can be configured as a spring device.
