[0056] Figures 3A to 31 show examples of a clip arrangement 70 which is a further development of the embodiments shown above . The clip arrangement 70 is configured for mounting on a rail or fastening on the rail 80 . The clip arrangement 70 comprises the housing 50 and the clip 10 . The rail 80 is a DIN rail . Thus , the clip 10 is implemented as DIN clip . The clip 10 is formed such that during insertion of the housing 50 with the clip 10 on the rail 80 , the clip 10 is moved away from the rail recess 59 of the housing 50 to allow a sliding of the first outer section 82 of the rail 80 in the recess on the third side 17 of the clip 10 and after this sliding, the clip 30 is moved back to the locked position of the clip 10 . The clip arrangement 70 is free of a coil spring . The first and the second deflectable bar 31 , 32 provide the force for the movement of the clip 10 to the locked position of the clip 10 .

[0057] In an example as shown in Figure 3B, a cross-section of the rail 80 is shown . The rail 80 can be reali zed as a DIN rail . The rail 80 is also named "top hat rail" . The rail 80 can be called "TS35 rail" in the USA. The rail 80 may be made of metal , for example steel . The rail 80 comprises an inner section 81 . Typically, the inner section 81 can be mounted on an equipment rack . Additionally, the rail 80 comprises a first and a second outer section 82 , 83 that are connected to the inner section 81 by a first and a second S-shaped section 84 , 85 . A thickness of a metal sheet of the rail 80 is typically 1 mm . The outer dimensions Al and Bl of the rail 80 may typically be: Al = 35 mm, Bl = 7.5 mm. Alternatively, the dimension Bl may be 15 mm. The inner section 81 has a dimension A2 : A2 = 25 mm. A length (not shown in Figure 3B) of the rail 80 is limited e.g. by a width of a rack in which the rail 80 is mounted.

[0058] As shown in Figure 3D, the first pin 29 of the first snap 25 is inserted in the first opening 61 in case of a locked position of the clip 10. The second pin 30 of the second snap 26 is inserted in the second opening 62 in case of the locked position of the clip 10. The first and the second beam 21, 22 are movable through the first and the second slot 63, 64 to the locked position of the clip 10. As shown in Figure 3E, the first and the second pin 29, 31 stop a further movement of the clip 10 away from the rail recess 59.

[0059] The clip arrangement 70 comprises a device out of a group comprising a low voltage switching and protection device, a circuit breaker, a switch, a disconnector, a relay and a controller. The device is housed by the housing 50.

[0060] For example, the DIN clip 10 goes in the housing 50 of a device. The device can be any low voltage device used for switching and protection. The device is e.g. a switching device. The device is mounted on a standard DIN rail 80 in a panel. The device is provided with the DIN clip 10 to satisfy this application need. The purpose of the DIN Clip 10 is to mount and demount the device, to hold the device in position, and to take the load and stress from the cables when the device is connected.

[0061] The clip arrangement 70 uses a holding feature and a guideway in the housing 50 to restrict backward movement and free fall of the clip 10. Two cantilever snaps 25, 26 deflect downward during forward movement of the clip 10. The two snaps 25, 26 provide locking and backward movement restriction for the clip 10 once in position. The deflectable bars 31, 32 cause bounce back action when the clip 10 moves backward to a specific distance after assembled position.

[0062] In Figures 3F to 3H, the mounting process is shown. The mounting is performed tool free. As shown in Figure 3F, first the housing 50 is locked at a pivot point (on the right side) . Angular rotation in opposite direction is performed. A downward force is provided on the housing 50. The downward force causes the clip 10 to move back compressing the first and the second deflectable bars 31, 32 (also named two deflecting features) of the clip 10.

[0063] As shown in Figure 3H, once the pivot point is crossed, the clip 10 bounces back to the initial position due to retracting force by the first and the second deflectable bars 31, 32 of the clip 10.

[0064] As shown in Figure 31, the demounting is performed by a tool 60, e.g. a screwdriver. The steps (not shown in the figures) are for example: Insert tool 60 inside the slit 33 provided in the in the clip 10. 2. Pull the clip 10 back in the direction against the force of the first and the second deflectable bars 31, 32 (compression) . 3. Angular rotation in opposite direction while holding the tool 60 in the slit 33 by one hand. 4. Keep moving the housing 50 in angular upward direction. The clip 10 will get released from the rail 80. 5. Now the housing 50 can be moved back and taken out from the rail 80. Advantageously, the housing 50 with the clip 10 can be demounted from the rail 80 .

[0065] Figure 4A shows a further example of a clip 10 of a clip arrangement 70 which is an alternative embodiment to the embodiment shown above . The first beam 27 has a first end and a second end which both protrude at the first side 15 of the clip 10 . The second beam 28 has a first end and a second end which both protrude at the second side 16 of the clip 10 . The first and the second beams 27 , 28 are implemented as leaf springs .

[0066] Figures 4B and 4C show a further example of a clip 10 of a clip arrangement 70 which is a further development of the embodiments shown above . The first deflectable bar 31 is implemented as a cantilever beam . The cantilever beam comprises a pin 37 which is configured to slide over the first housing pin 57 during insertion of the clip 10 into the housing 50 .

[0067] The clip arrangement 70 comprises a molding feature for snap deflection; a molding feature with guideway; a fix ended snap feature deflecting inward during forward movement of the clip 10 , a molding feature in the housing 50 to restrict backward movement and free fall of the clip 10 , and a molding feature for snap deflection that causes bounce back action when the clip 10 is moved backward to speci fic distance after assembled position .

[0068] Figures 5A and 5B show a further example of a housing 50 of a clip arrangement 70 which is a further development of the embodiments shown above . Figures 6A and 6B show a further example of a clip arrangement 70 with a clip 10 and a housing 50 which is a further development of the embodiments shown above .

[0069] The clip 10 is a part which goes in the housing 50 of the device ( the device can be e . g . any low voltage product used for switching and protection) . An example of the device is a switching device . The device is mounted on a standard DIN rail 80 in a panel . To satis fy this application need the device is provided with the DIN clip 10 . The purpose of the DIN clip 10 is to mount and demount the device on the rail 80 , to hold the device in position, and to withstand the load and stress from the cables when connected to device , without breaking .

[0070] The clip 10 is designed to meet the mounting and demounting requirements . The clip 10 comes with a single piece design; examples of key features are the first and the second deflectable bar 31 , 32 , the first housing pin 57 reali zed by molding, the first and the second opening 61 , 62 and the two cantilever snaps 25 , 26 . The DIN clip 10 is assembled in the housing 50 from the back, deflecting the snaps 25 , 26 downward until they reach the window openings 61 , 62 . In the same cycle the first and the second deflectable bars 31 , 32 deflect outward against the first housing pin 57 until the clip 10 reaches its static or closed position . Mounting and demounting the first and the second deflectable bars 31 , 32 and the first housing pin 57 achieve the desired functions .

[0071] The embodiments shown in Figures 1A to 6B as stated represent example embodiments of a clip arrangement 70 ; therefore , they do not constitute a complete list of all embodiments according to the clip arrangement . Actual arrangements may vary from the embodiments shown in terms of parts, structures, and shape, for example.
