Electric plug with elastic press-on elements

1. An electric plug, comprising:

an outer housing;

an inner housing adapted to be plugged into the outer housing along an assembly direction; and

a press-on element including a bracket projecting from the outer housing to the inner housing or from the inner housing to the outer housing, the bracket comprising:

a first projection;

a second projection; and

a tab extending between the first projection and the second projection, the first and second projections and the tab defining a recess formed between the press-on element and the inner housing or the outer housing, the tab of the press-on element adapted to be deflected elastically transversely to the assembly direction and in a direction of the recess from a first resting position into a second deflected position as the inner housing is plugged into the outer housing, the press-on element remaining in the second deflected position when the inner housing is in a mounted state within the outer housing and producing a press-fit connection between the inner housing and the outer housing in the mounted state.

2. The electric plug of claim 1 , wherein the press-on element is disposed between the outer housing and the inner housing and secures the inner housing within the outer housing in the mounted state with substantially only a friction force generated between the press-on element and a surface of the outer housing or the inner housing.

3. The electric plug of claim 1 , wherein the press-on element and the inner housing and/or the outer housing comprise no opposing surfaces in a direction of disassembly when the inner housing is in the mounted state within the outer housing.

4. The electric plug of claim 1 , wherein the press-on element extends transversely to the assembly direction across a gap between the inner housing and the outer housing.

5. The electric plug of claim 1 , wherein the inner housing or the outer housing is formed integrally as a monolithic component with the press-on element.

6. The electric plug of claim 1 , wherein a pair of press-on elements are arranged on a pair of mutually adjacent lateral surfaces between the inner housing and the outer housing.

7. The electric plug of claim 1 , wherein a pair of press-on elements are arranged on a pair of mutually opposite lateral surfaces between the inner housing and the outer housing.

8. The electric plug of claim 1 , wherein the press-on element extends across a corner between a pair of adjacent lateral surfaces of the inner housing.

9. The electric plug of claim 1 , wherein the press-on element has a projecting contact-pressure surface.

10. The electric plug of claim 9 , wherein the contact-pressure surface engages a support surface of the outer housing or the inner housing in the mounted state of the inner housing and the outer housing.

11. The electric plug of claim 10 , wherein the contact-pressure surface is complementary to the support surface.

12. The electric plug of claim 1 , wherein the press-on element has a substantially U-shaped cross-section in the assembly direction.

13. The electric plug of claim 1 , wherein the press-on element is molded on a wall of the outer housing or the inner housing.

14. The electric plug of claim 1 , wherein the second deflected position corresponds to a position of maximum deflection of the press-on element as the inner housing is plugged into the outer housing.

15. An inner housing, comprising:

a base body extending along a longitudinal axis and configured to be inserted into an outer housing in an assembly direction; and

a press-on element including a bracket projecting from the inner housing, the bracket comprising:

a first projection;

a second projection; and

a tab extending between the first projection and the second projection, the first and second projections and the tab defining a recess formed between the press-on element and the inner housing, the tab of the press-on element adapted to be deflected transversely to the assembly direction and in a direction of the recess from a first resting position into a second deflected position as the inner housing is inserted into the outer housing, the press-on element remaining in the second deflected position when the inner housing is in a mounted state within the outer housing and producing a press-fit connection between the inner housing and the outer housing in the mounted state.

16. The inner housing of claim 15 , wherein the press-on element defines a curved contact-pressure surface having an apex configured to engage with a surface of the outer housing when the inner housing is received within the outer housing.

17. The inner housing of claim 15 , wherein the bracket defines a portion of:

a first collar formed about a wall of the body and extending in a direction transversely to the assembly direction, the press-on element further including:

a second collar formed about the wall of the body and extending in a direction transversely to the assembly direction; and

a contact-pressure projection defining a contact surface extending between the first collar and the second collar.

18. An outer housing, comprising:

a receptacle adapted to receive an inner housing; and

a press-on element arranged in the receptacle and including a bracket projecting from the outer housing into the receptacle, the bracket comprising:

a first projection;

a second projection; and

a tab extending between the first projection and the second projection, the first and second projections and the tab defining a recess formed between the press-on element and the outer housing, the tab of the press-on element adapted to be deflected by the inner housing in a direction of the outer housing and in a direction of the recess from a first resting position into a second deflected position as the inner housing is received into the outer housing, the press-on element remaining in the second deflected position when the inner housing is in a mounted state within the outer housing and producing a press-fit connection between the inner housing and the outer housing in the mounted state.
