As can be seen in connection with fig. 1-4, the mounting clip 10 is capable of being mounted to a DIN rail 20. The mounting clip 10 includes:

a main body 11 including a first end 111 and a second end 112 disposed opposite to each other;

at least one first hook 12 disposed at the first end 111 for locking a first side 21 of the DIN rail 20;

at least one second hook 13 disposed at the second end 112 for locking a second side edge 22 of the DIN rail 20, wherein the first side edge 21 and the second side edge 22 are respectively located at two opposite sides of the DIN rail 20, and the first hook 12 and the second hook 13 are both located at a first side 113 of the main body 11;

a first elastic arm 14 disposed at the first end 111 and capable of elastically deforming in a first direction R1 to generate a first elastic force F1 pressing the first side 21 in a first direction R1, wherein the first direction R1 faces the first side 113; and

a second elastic arm 15 disposed at the second end 112 and capable of elastically deforming in the first direction R1 to generate a second elastic force F2 pressing the second side 22 in the first direction R1.

In addition, the second elastic arm 15 is also configured to be elastically deformed in a second direction R2 to generate a third elastic force F3 pressing the second side 22 in the second direction R2, and the first end 111 and the second end 112 are aligned along the second direction R2.

Specifically, the main body portion 11 has opposite ends, i.e., a first end 111 and a second end 112; and opposite sides, a first side 113 and a second side 114. The first hook 12 and the second hook 13 are respectively positioned at the first end 111 and the second end 112. The first hook 12 and the second hook 13 are both located on the first side 113 of the main body 11. The first direction R1 is toward the first side 113, that is, the first direction R1 is perpendicular to the surface of the main body 11 on the first side 113. The second direction R2 passes through the first end 111 and the second end 112. The third direction R3 is perpendicular to the first direction R1 and the second direction R2. When the mounting clip 10 is mounted with the DIN rail 20, the first direction R1 is the thickness direction of the DIN rail 20, the second direction R2 is the width direction of the DIN rail 20, and the third direction R3 is the length direction of the DIN rail 20. The first elastic arm 14 and the second elastic arm 15 are located at the first end 111 and the second end 112, respectively. The first elastic arm 14 is capable of being elastically deformed in a first direction R1. When the mounting clip 10 and the DIN rail 20 are mounted, the first hook 12 catches the first side 21 of the DIN rail 20, and the first elastic arm 14 generates a first elastic force F1 pressing the first side 21 in the first direction R1. At the same time, the second hook 13 catches the second side 22 of the DIN rail 20. The second resilient arm 15 is forced by the second side edge 22 of the DIN rail 20 in the first direction R1. Preferably, the second resilient arm 15 is also subjected to a force in the second direction R2 by the second side edge 22 of the DIN rail 20, i.e. is deformed in both directions. Thus, the second elastic arm 15 generates a second elastic force F2 pressing the second side 22 in the first direction R1, and generates a third elastic force F3 pressing the second side 22 in the second direction R2 (the direction of the third elastic force F3 is opposite to the second direction R2). In use, the mounting clip 10 is fixedly mounted to the device housing 30 from the second side 114 and to the DIN rail 20 from the first side 113. Thus, the mounting clip 10 can be mounted with the DIN rail 20 independently without the need for the casing of the device, and has simple structure and convenient mounting; the mounting clip 10 can clamp the DIN rail 20 in the thickness direction (i.e., the first direction R1), has good compatibility with thickness deviation of the DIN rail 20, and prevents equipment from moving along the DIN rail 20 (i.e., the third direction R3).

In an exemplary embodiment, the second elastic arm 15 includes a V-shaped portion 151 and an L-shaped portion 152, an opening 1511 of the V-shaped portion 151 faces the first side 113 and includes a third end 1513 and a fourth end 1514, the third end 1513 is fixedly connected to the body portion 11, the fourth end 1514 is fixedly connected to the L-shaped portion 152, the L-shaped portion 152 includes a first segment 1521 and a second segment 1522, the first segment 1521 is fixedly connected to the fourth end 1514 along the second direction R2, and the second segment 1522 is fixedly connected to the first segment 1521 along the first direction R1. When installed, the second side 22 of the DIN rail 20 contacts the L-shaped portion 152. On the one hand, the second side 22 of the DIN rail 20 presses the second spring arm 15 in the first direction R1 to deform it, generating a second spring force F2 in the first direction R1; on the other hand, the edge of the second side 22 of the DIN rail 20 is caught by the L-shaped portion 152, and the second elastic arm 15 is stretched in the second direction to deform, thereby generating the third elastic force F3 in the second direction R2. The second elastic arm 15 is simple in structure.

In an exemplary embodiment, as shown in fig. 2, the main body 11 is sheet-shaped, the bottom of the V-shaped portion 151 is located at the second side 114 of the sheet-shaped main body 11, the first segment 1521 of the L-shaped portion 152 is located at the first side 113 of the sheet-shaped main body 11, and the first side 113 and the second side 114 are respectively located at two opposite sides of the sheet-shaped main body 11. Thus, when the second side 22 of the DIN rail 20 contacts the main body 11 during installation, the first segment 1521 is pressed to be flush with the main body 11, the second elastic arm 15 is deformed in the first direction R1, and at the same time, the second elastic arm 15 is hooked by the second segment 1522 to move along the second direction R2, and the second elastic arm 15 is deformed in the second direction R2. The second elastic arm 15 is simple in structure.

In an exemplary embodiment, the first resilient arm 14 is a straight bar and the free end thereof is provided with a protrusion 141 facing the first side 113. The projection 141 is located on the first side 113 of the sheet-like body 11, so that the first side 21 of the DIN rail 20 can be pressed flush with the body 11 when it is mounted on the body 11, and the first resilient arm 14 is deformed in the first direction R1. The first elastic arm 14 is simple in structure.

In an exemplary embodiment, there are two second hooks 13, and the second elastic arm 15 is located between the two second hooks 13. In this way, the forces on the mounting clip 10 are more balanced. In an exemplary embodiment, the shortest distance of the second hook 13 from the second end 112 of the main body 11 in the first direction R1 is greater than the thickness of the second side edge 22 of the DIN rail 20.

In an exemplary embodiment, the free end 121 of the first hook 12 is inclined towards the main body portion 11 and the free end 131 of the second hook 13 is inclined away from the main body portion 11.

1, fixing and mounting the mounting clip 10 and the equipment shell 30.

2, the second hook 13 of the mounting clip 10 is hung on the second side 22 of the DIN rail 20.

3, the mounting clip 10 and the device housing 30 are rotated about the contact point of the second hook 13 and the second side 22 as a fulcrum, so that the first hook 12 contacts the first side 21 of the DIN rail 20.

4, pressing the device housing 30 makes the first side 21 snap into the first hook 12.

The free end 121 of the first hook 12 is inclined toward the main body 11 so that the first side 21 can be easily engaged with the first hook 12 in step 4. The free end 131 of the second hook 13 is inclined away from the main body 11, so that the second hook 13 can be hung on the second side 22 more conveniently in step 2.

In an exemplary embodiment, the mounting clip 10 further includes one or more of at least one screw mounting hole 16, at least one retaining hole 17, and at least one retaining slot 18. The mounting clip 10 is fixedly mounted to the equipment enclosure 30 by the screw mounting clip 16 and a screw 161. The device housing 30 is typically provided with a guide mechanism 171 that mates with the positioning hole 17, and a positioning mechanism 181 that mates with the positioning slot 18. The mounting clip 10 can accommodate different devices.

In an exemplary embodiment, the mounting clip 10 is made of a metal material and is integrally formed. The mounting clip 10 of metal material has better resistance to deformation.
