Abstract
An electrical contact includes a contact body and a contact spring. The contact spring is disposed in the contact body and has a locking arm locking the contact spring in a housing. The locking arm moves in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring.
Claims23
An electrical contact, comprising:
- a contact body;
- and
- a contact spring connected to the contact body and having a locking arm locking the electrical contact in an electrical connector housing, the locking arm having an attached end attached to a contact spring collar of the contact spring and a free end connected to the attached end at a bending point, the attached end extending over the contact body and abutting an edge of a wall of the contact body in an undeformed state of the locking arm, the locking arm moving in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring.
An electrical connector for a cable, comprising:
- a housing;
- and
- an electrical contact including a contact body and a contact spring connected to the contact body and having a locking arm locking the electrical contact in the housing, the locking arm having an attached end attached to a contact spring collar of the contact spring and a free end connected to the attached end at a bending point, the attached end extending over the contact body and abutting an edge of a wall of the contact body in an undeformed state of the locking arm, the locking arm moving in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring.
A prefabricated cable, comprising:
- a cable;
- and
- an electrical contact connected to the cable including a contact body and a contact spring connected to the contact body, the contact spring having a locking arm locking the electrical contact in an electrical connector housing, the locking arm having an attached end attached to a contact spring collar of the contact spring and a free end connected to the attached end at a bending point, the attached end extending over the contact body and abutting an edge of a wall of the contact body in an undeformed state of the locking arm, the locking arm moving in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring.
An electrical contact, comprising:
- a contact body having a body support;
- and
- a contact spring connected to the contact body and having a locking arm locking the electrical contact in an electrical connector housing, the locking arm having an attached end attached to a contact spring collar of the contact spring and a free end and moving in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring, the attached end and free end are connected at a bending point and form a bending angle, a deformability of the locking arm is adjusted by adjusting an endpoint of the body support that abuts the attached end, by adjusting a length of the attached end with respect to a length of the free end, and/or by adjusting a position of the bending point, the length of the attached end is calculated by a formula:
- L130=c*L124, wherein
- L124 is a longitudinal distance of the endpoint of the body support with respect to a connection point between the contact spring and the contact body, and the factor c is equal to or greater than approximately 1.0 to approximately 2.5.
2 more elements
An electrical contact, comprising:
- a contact body having a body support;
- and
- a contact spring connected to the contact body and having a locking arm locking the electrical contact in an electrical connector housing, the locking arm moving in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring, the locking arm having an attached end attached to a contact spring collar of the contact spring and protruding over and abutting the body support and a free end connected to the attached end, a deformability of the locking arm is adjusted by adjusting an endpoint of the body support and by adjusting a length of the attached end with respect to a length of the free end.
