[0029] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0031] like Figure 1-8 As shown, this embodiment provides a mounting frame 1 of a connector, including a frame body 10 and a spring piece 20. The frame body 10 includes a first side plate 11 and a second side plate 12 arranged opposite to the first side plate 11, a first end plate 13 and a second end plate 14 arranged opposite to the first end plate 13, the first side plate 11 and the second side plate 12 are parallel to each other, the first end plate 13 and the second end plate 14 are parallel to each other, the side plates 11 and 12 are perpendicular to the end plates 13 and 14, and the first side plate 11, the second side plate 12, the first end plate 13 and the second end plate 14 together enclose an inner cavity 16 of the frame body 10. Referring to Figure 7-8 , the connector module 2 can be inserted into the inner cavity 16 of the frame body 10 along the direction F and fixed. The outer side surfaces of the first side plate 11 and the second side plate 12 of the frame body 10 are provided with spring clip installation positions 15, and the spring clip installation positions 15 are used to assemble the spring clip 20, so that the spring clip 20 is assembled on the outer side surface of the frame body 10. The spring clip 20 is used to fix the connector module 2 in the inner cavity 16 of the frame body 10. The inner cavity 16 is provided with at least one installation position of the connector module 2. In this embodiment, Figure 6-8 As shown, the inner cavity 16 is provided with 6 installation positions for the connector modules 2. Of course, the inner cavity 16 can also be provided with more or fewer installation positions for the connector modules 2.

[0032] The spring piece 20 is made of elastic material. The spring piece 20 has a fixed side 21, a transition section 22 and a movable side 23. The fixed side 21 is used to fix the spring piece 20 on the frame body 10; the movable side 23 is provided with a fixing structure 27, and the fixing structure 27 is used to fix the connector module 2 in the inner cavity 16 of the frame body 10. The transition section 22 is connected between the fixed side 21 and the movable side 23. At least the transition section 22 has elastic deformation capability. The spring piece 20 can produce elastic deformation to cause the movable side 23 to displace, and the displacement of the movable side 23 can cause the fixing structure 27 to engage or separate with the connector module 2.

[0033] In this embodiment, the fixing structure 27 is a protruding tongue piece 27. Furthermore, the protruding tongue piece 27 is a bent structure, so that the strength of the protruding tongue piece 27 can be increased. The first side plate 11 and the second side plate 12 are provided with an opening 154, and the protruding tongue piece 27 extends into the opening 154. The lower edge 272 of the fixing structure 27 is arranged straight, and the lower edge 272 abuts against the hanging platform 201 of the connector module 2, so as to fix the connector module 2 in the inner cavity 16 of the frame body 10. The upper edge 271 of the fixing structure 27 is arranged obliquely, so that when the connector module 2 is moved along Figure 7 When the connector module 2 is inserted into the inner cavity 16 of the frame body 10 in the middle F direction, the upper edge 271 of the fixing structure 27 can play a guiding role, and the connector module 2 slides along the upper edge 271 and opens the movable side 23 of the spring 20, thereby generating enough space for the connector module 2 to move along the upper edge 271. Figure 7 The connector module 2 is inserted into the inner cavity 16 of the frame body 10 in the middle F direction. When the connector module 2 is inserted into the inner cavity 16 of the frame body 10 and is in place, the spring sheet 20 can automatically rebound, and the fixing structure 27 of the spring sheet 20 is engaged with the connector module 2, thereby fixing the connector module 2 in the inner cavity 16 of the frame body 10.

[0034] A limiting structure is provided between the spring piece 20 and the frame body 10 for limiting the displacement of the movable side 23, thereby preventing the spring piece 20 from being easily plastically deformed and failing when the connector module 2 withdraws from the inner cavity 16 of the frame body 10 when the movable side 23 of the spring piece 20 is not limited, thereby improving the service life of the installation frame 1.

[0035] The spring sheet 20 is provided with a first limiting portion 26. In this embodiment, the first limiting portion 26 is a limiting tongue piece 26. The spring sheet installation position 15 of the frame body 10 is provided with a second limiting portion 151. In this embodiment, the second limiting portion 151 is a spring sheet limiting rib 151. The limiting tongue piece 26 can be abutted and matched with the spring sheet limiting rib 151 due to the displacement of the movable side 23, thereby forming a limiting structure between the spring sheet 20 and the frame body 10. When the first limiting portion 26 abuts against the second limiting portion 151, the fixing structure 27 can be separated from the connector module 2. In other embodiments, the first limiting portion 26 and the second limiting portion 151 can also be in other forms, such as a protruding boss. In this embodiment, the first limiting portion 26 is a limiting tongue piece 26, and the second limiting portion 151 is a spring sheet limiting rib 151, which has a simple structure and is more convenient to manufacture.

[0036] When the spring clip 20 is installed with the frame body 10 and the spring clip 20 is not subjected to external force, there is a gap between the limiting tongue 26 and the spring clip limiting rib 151, so that the gap can allow the active side 23 of the spring clip 20 to produce a certain displacement when a certain elastic deformation is generated, which is conducive to the connector module 2 being installed into the inner cavity 16 of the frame body 10 or removed from the inner cavity 16.

[0037] In this embodiment, the spring limiting rib 151 is located on the side of the limiting tongue 26 away from the inner cavity 16 , and the displacement of the movable side 23 away from the inner cavity 16 separates the fixing structure 27 from the connector module 2 .

[0038] In other embodiments, the limiting structure between the spring piece 20 and the frame body 10 may also be a traction member provided between the spring piece 20 and the frame body 10 , such as a traction rope.

[0039] In this embodiment, two limiting tongues 26 are provided, and the two limiting tongues 26 extend outward from both sides of the movable side 23 respectively. Since the movable side 23 is the position with the largest displacement on the spring sheet 20, compared with the limiting tongues 26 provided at other positions of the spring sheet 20, the limiting tongues 26 extend outward from both sides of the movable side 23, which can form the most effective restriction on the movable side 23. Further, movable side reinforcing ribs 29 are provided on both sides of the movable side 23, and the rigidity of the movable side 23 can be increased by the movable side reinforcing ribs 29, so as to further prevent the movable side 23 from plastic deformation and failure, and improve the service life of the spring sheet 20. In this embodiment, the movable side reinforcing ribs 29 are provided between the limiting tongues 26 and the movable side 23, and the gap between the limiting tongues 26 and the spring limiting ribs 151 can be increased by the movable side reinforcing ribs 29, so as to facilitate the insertion or removal of the connector module 2 relative to the inner cavity 16 of the frame body 10.

[0040] like Figure 1-8As shown, the fixed side 21 is used to fix the spring piece 20 on the frame body 10. A snap-on tongue piece 24 is provided on the left and right sides of the fixed side 21. The snap-on tongue piece 24 is a bent tongue piece, and a snap interface 152 is provided on both sides of the lower part of the spring piece installation position 15. The snap-on tongue piece 24 can be snapped into the snap interface 152, thereby forming a limit for the spring piece 20.

[0041] The fixed side 21 is also provided with a fixing structure 25, which is a fixed bayonet. A fixing boss 153 is provided on the spring piece mounting position 15. The fixing structure 25 is used to engage with the fixing boss 153, so that on the basis of the engagement of the engaging tongue 24 and the engaging interface 152, a firm limit is formed for the spring piece 20 on the spring piece mounting position 15.

[0042] A connecting section 28 is also provided between the fixed side 21 and the transition section 22. The connecting section 28 is bent at an angle relative to the fixed side 21 and the transition section 22. Therefore, compared with the straight state between the fixed side 21 and the transition section 22, the fixed side 21 has a bending process angle A relative to the transition section 22. The bending process angle A is greater than 0 degrees. Therefore, when the spring clip 20 is installed on the spring clip installation position 15, the pre-tightening force of the spring clip 20 can be increased, so that the spring clip 20 can more firmly fix the connector module 2 in the inner cavity 16 of the frame body 10.

[0043] The steps of assembling the frame body 10 and the spring sheet 20 are as follows:

[0044] The fixed side 21 of the spring sheet 20 is installed from the bottom of the frame body 10, and then the spring sheet 20 is pushed to the top of the frame body 10 until the snap-on tongue 24 of the spring sheet 20 is snap-fitted into the snap-on interface 152, and at the same time, the fixing structure 25 is snap-fitted with the fixing boss 153 to complete the assembly of the frame body 10 and the spring sheet 20.

[0045] The installation steps of connector module 2 are as follows:

[0046] 1. Align the connector module 2 with the mounting position of the connector module 2 in the inner cavity 16;

[0047] 2. Press the connector module 2 into the mounting frame 1, and the hanging platform 201 of the connector module 2 pushes the movable side 23 of the spring sheet 20 through the inclined surface of the upper edge 271 of the fixing structure 27 of the spring sheet 20;

[0048] 3. Continue to press the connector module 2 into the installation frame 1. When a "click" sound is heard, the connector module 2 is installed in place, the spring piece 20 automatically rebounds, and the fixing structure 27 of the spring piece 20 buckles the hanging platforms 201 on both sides of the connector module 2 to complete the installation.

[0049] The steps to disassemble the connector module are as follows:

[0050] 1. Take out the assembly of the connector module 2 and the mounting frame 1;

[0051] 2. The spring clips 20 on both sides of the mounting frame 1 are flipped outward at the same time until the limiting tongue pieces 26 of the spring clips 20 contact the spring clip limiting ribs 151 of the frame body 10, so that the spring clips 20 are in a force-opened state. At this time, the fixing structure 27 of the spring clip 20 is separated from the hanging platform 201 of the connector module 2, and the connector module 2 is pushed upward until the connector module 2 is separated from the mounting frame 1, and the disassembly is completed.
