DIN rail latching arrangement
View Patent ↗A latching arrangement for detachably mounting a device on a DIN rail. A support member configured to be mounted on the DIN rail. A guiding slot configured on a same side of the device on which the support member is configured. An engaging lug received in the guiding slot and adapted to move between an engaging, extended configuration and a retracted, disengaging configuration. An urging element cooperating with the engaging lug and the device, the urging element adapted to be configured between a first operative configuration in which the urging element urges the engagement lug towards the support member and a second operative configuration in which said urging element is moved to facilitate moving of the engaging lug away from said support member.
1. A latching arrangement for detachably mounting a device on a German Institute for Standardization (DIN) rail, the latching arrangement comprising:
a support member configured on a side of the device to be mounted on the DIN rail, said support member adapted to receive the DIN rail to facilitate aligning of the device with respect to the DIN rail;
a guiding slot configured on the same side of the device on which said support member is configured and spaced away from said support member;
an engaging lug received in said guiding slot and adapted to move between an extended configuration in which said engaging lug moves towards said support member and engages with a lip portion of the DIN rail received by said support member and a retracted configuration in which said engaging lug is pulled away from said support member to disengage from said lip portion of the DIN rail received by said support member; and
an urging element cooperating with said engaging lug and the device, said urging element adapted to be configured between a first operative configuration in which said urging element urges said engagement lug towards said support member for facilitating engagement of said engagement lug with said lip portion of the DIN rail and a second operative configuration in which said urging element is moved by an applied force to facilitate moving of said engaging lug from the extended configuration, in which said engaging lug engages with a lip portion of the DIN rail received by said support member, to the retracted configuration, in which said engaging lug is pulled away from said support member to disengage from said lip portion of the DIN rail received by said support member, wherein said urging element springs back to said first operative configuration after said applied force is removed such that said urging element returns the engaging lug to the extended configuration after said applied force is removed;
wherein said engaging lug comprises a support structure extending around a portion of said urging element to facilitate retention of said urging element within said engaging lug.
2. The latching arrangement as claimed in claim 1 , wherein said urging element is a spring element adapted to be configured between a normal, non-compressed configuration in which said spring urges said engagement lug towards said support member and a compressed configuration in which said spring facilitates moving of said engaging lug away from said support member for causing disengagement of said engagement lug from said lip portion of the DIN rail.
3. The latching arrangement as claimed in claim 1 , wherein said urging element is a compression spring.
4. The latching arrangement as claimed in claim 1 , wherein said urging element is a helical compression spring.
5. The latching arrangement as claimed in claim 1 , wherein said urging element is a leaf spring.
6. The latching arrangement as claimed in claim 1 , wherein said urging element is an extension spring.
7. The latching arrangement as claimed in claim 1 , wherein said engaging lug is provided with a handle adapted to facilitate pulling of said engaging lug away from said support member to disengage said engaging lug from said lip portion of the DIN rail received over said support member.
8. A latching arrangement for detachably mounting a device on a German Institute for Standardization (DIN) rail, the latching arrangement comprising:
a support member configured on a side of the device to be mounted on the DIN rail, said support member adapted to receive the DIN rail to facilitate aligning of the device with respect to the DIN rail;
a guiding slot configured on the same side of the device on which said support member is configured and spaced away from said support member;
an engaging lug received in said guiding slot and adapted to move between an extended configuration in which said engaging lug moves towards said support member and engages with a lip portion of the DIN rail received by said support member and a retracted configuration in which said engaging lug is pulled away from said support member to disengage from said lip portion of the DIN rail received by said support member; and
an urging element cooperating with said engaging lug and the device, said urging element adapted to be configured between a first operative configuration in which said urging element urges said engagement lug towards said support member for facilitating engagement of said engagement lug with said lip portion of the DIN rail and a second operative configuration in which said urging element is moved by an applied force to facilitate moving of said engaging lug from the extended configuration, in which said engaging lug engages with a lip portion of the DIN rail received by said support member, to the retracted configuration, in which said engaging lug is pulled away from said support member to disengage from said lip portion of the DIN rail received by said support member, wherein said urging element springs back to said first operative configuration after said applied force is removed such that said urging element returns the engaging lug to the extended configuration after said applied force is removed; and wherein said urging element is integrally formed with said engaging lug; and wherein said comprises a support structure extending around a portion of said urging element within said engaging lug.
