Description

Mounting frame of a connector

[0001] Cross-reference to related applications

[0002] The present application claims priority to the Chinese patent application No. CN202411258981.X, filed on September 9, 2024, and entitled "Mounting frame of a connector", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of connector mounting, in particular to a mounting frame of a connector. BACKGROUND

[0004] With the development of industry, industrial products are increasingly integrated and refined, resulting in the need to meet the transmission requirements of various signals, power and the like in limited space. Therefore, connectors and their mounting frames have been widely used, and their importance has become increasingly prominent.

[0005] In the prior art, such as the retaining frame (100) disclosed in patent CN114731010A, the fixed area of the wall segment (16) cooperates with the protruding element (210) of the contact insert (200) to achieve fixation. However, this scheme has the following defects: 1. The fixed tabs (31, 32) of the wall segment (16) need to be elastically deformed to release the protruding element (210) when the contact insert (200) is withdrawn, but the active range of the wall segment (16) is not physically limited. Long-term repeated operation can easily cause the wall segment (16) to fail due to excessive deformation and plastic deformation; 2. The fixed tabs (31, 32) of the wall segment (16) rely only on material elasticity for resetting, which can easily fatigue and break under frequent plugging and unplugging or external force impact, reducing the service life of the frame.

[0006] The bracket (3) disclosed in patent CN105977693B achieves fixation by cooperation of the arcuate segment (350) of the locking element (35) with the protruding element (420) of the contact insert (4). Similarly, this scheme has the following defects: the arcuate segment (350) is bent outward and moves to release the protruding element (420) when the contact insert (4) is withdrawn, but the movement stroke of the arcuate segment (350) has no physical limit. Long-term repeated operation can easily cause the locking element (35) to fail due to fatigue.

[0007] Therefore, it can be seen that the movable side of the fixing spring of the existing mounting frame adopts an open structure, and the spring is prone to plastic deformation and failure when the connector is withdrawn without being limited, thus reducing the service life of the mounting frame and making the product less reliable.

[0039] To further illustrate the embodiments, the present application provides accompanying drawings. These drawings are part of the disclosure of the present application, which mainly serve to illustrate the embodiments, and can be used to explain the operating principles of the embodiments in conjunction with the relevant description. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementations and advantages of the present application. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0040] The present application will be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] As shown in Figs. 1-8, the present embodiment provides a mounting frame 1 of a connector, which includes a frame body 10 and a spring 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 first side plate 11 is perpendicular to the first end plate 13 and the second end plate 14 respectively, the second side plate is perpendicular to the first end plate 13 and the second end plate 14 respectively, 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 Figs. 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 of the first side plate 11 and the second side plate 12 of the frame body 10 is provided with a spring installation position 15, which is used to assemble the spring 20, so that the spring 20 is assembled on the outer side of the frame body 10. The spring 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 the present embodiment, as shown in Figs. 6-8, the inner cavity 16 is provided with six installation positions of the connector module 2. Of course, the inner cavity 16 can also be provided with more or less installation positions of the connector module 2.

[0042] The elastic sheet 20 is made of elastic material. The elastic sheet 20 has a fixed side 21, a transition section 22 and a movable side 23. The fixed side 21 is used to fix the elastic sheet 20 on the frame body 10. The movable side 23 is provided with a first fixing structure 27, which 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 elastic sheet 20 can produce elastic deformation so that the movable side 23 is displaced. The displacement of the movable side 23 can make the first fixing structure 27 engage or separate from the connector module 2.

[0043] In the embodiment, the first fixing structure 27 is a protruding tongue 27. Further, the protruding tongue 27 includes a first extension section 273 and a second extension section 274. The first extension section 273 extends to form in the position where the elastic sheet 20 is installed on the frame body 10, towards the inner cavity 16 of the frame body 10. The second extension section 274 extends to form from one end of the first extension section 273 away from the elastic sheet 20, towards the direction close to the axis of the elastic sheet 20. The first extension section 273 and the second extension section 274 form a bending structure, so as to increase the strength of the protruding tongue 27. The first side plate 11 and the second side plate 12 are provided with an opening 154, and the protruding tongue 27 extends into the opening 154. The protruding tongue 27 has a lower edge 272 and an upper edge 271. The lower edge 272 is formed along the second extension section 274, and the lower edge 272 is arranged straight. The lower edge 272 abuts against the hanging table 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 is arranged obliquely along the first extension section 273 and the second extension section 274. When the connector module 2 is inserted into the inner cavity 16 of the frame body 10 along the direction F in FIG. 7, the upper edge 271 can play a guiding role. The connector module 2 slides along the upper edge 271 and pushes open the movable side 23 of the elastic sheet 20, so as to generate sufficient space for the connector module 2 to be inserted into the inner cavity 16 of the frame body 10 along the direction F in FIG. 7. After the connector module 2 is inserted into the inner cavity 16 of the frame body 10 in place, the elastic sheet 20 can automatically rebound, and the first fixing structure 27 of the elastic sheet 20 is clamped on the connector module 2, so as to fix the connector module 2 in the inner cavity 16 of the frame body 10.

[0044] Further, the number of the protruding tongues 27 is two, and the two protruding tongues 27 are arranged towards each other.

[0045] The limiting structure 30 is arranged between the elastic sheet 20 and the frame body 10, and is used for limiting the displacement of the movable side 23, so as to prevent the movable side 23 of the elastic sheet 20 from being plastically deformed and failed when the connector module 2 is taken out of the inner cavity 16 of the frame body 10 without being limited, and improve the service life of the mounting frame 1.

[0046] The first limiting part 26 is arranged on the elastic sheet 20, and the second limiting part 151 is arranged on the elastic sheet mounting position 15 of the frame body 10. In the embodiment, the first limiting part 26 is a limiting tongue 26 which is formed by extending outward from one side of the movable side 23, and the second limiting part 151 is an elastic sheet limiting rib 151 which is used for limiting the continuous displacement of the limiting tongue 26. The limiting tongue 26 can abut against the elastic sheet limiting rib 151 due to the displacement of the movable side 23, so as to form the limiting structure 30 between the elastic sheet 20 and the frame body 10. When the first limiting part 26 abuts against the second limiting part 151, the first fixed structure 27 can be separated from the connector module 2. In other embodiments, the first limiting part 26 and the second limiting part 151 can also be other forms, such as a protruding boss and the like. In the embodiment, the first limiting part 26 is the limiting tongue 26, and the second limiting part 151 is the elastic sheet limiting rib 151, so the structure is simple and the manufacturing is more convenient.

[0047] When the elastic sheet 20 is installed on the frame body 10 and is not subjected to external force, there is a gap between the limiting tongue 26 and the elastic sheet limiting rib 151, so that the gap can allow the movable side 23 to displace a certain distance when the elastic sheet 20 is elastically deformed by a certain amount, thereby facilitating the connector module 2 to be installed in or taken out of the inner cavity 16 of the frame body 10.

[0048] In other embodiments, the limiting structure 30 between the elastic sheet 20 and the frame body 10 can also be a traction member arranged between the elastic sheet 20 and the frame body 10, such as a traction rope and the like.

[0049] In the embodiment, two limiting tongues 26 are arranged, and the two limiting tongues 26 extend outward from the two sides of the movable side 23. Since the movable side 23 is the position with the largest displacement on the elastic sheet 20, compared with the case where the limiting tongues 26 are arranged at other positions on the elastic sheet 20, the limiting tongues 26 extending outward from the two sides of the movable side 23 can most effectively limit the movable side 23. Further, the movable side reinforcing ribs 29 are arranged at the two sides of the movable side 23, and the movable side reinforcing ribs 29 can increase the rigidity of the movable side 23, thereby further preventing the movable side 23 from being deformed plastically and failing, and improving the service life of the elastic sheet 20. In the embodiment, the movable side reinforcing ribs 29 are arranged between the limiting tongues 26 and the movable side 23, the movable side reinforcing ribs 29 are substantially perpendicular to the plane in which the movable side 23 is arranged, the movable side reinforcing ribs are substantially perpendicular to the plane in which the limiting tongues 26 are arranged, and the movable side 23 and the limiting tongues 26 are arranged substantially in parallel, so that the movable side 23 and the limiting tongues 26 form a stepped surface. The movable side reinforcing ribs 29 can also increase the gap between the limiting tongues 26 and the elastic sheet limiting ribs 151, thereby making it more convenient to load or unload the connector module 2 relative to the inner cavity 16 of the frame main body 10.

[0050] As shown in FIGS. 1-8, the fixed side 21 is used to fix the elastic sheet 20 on the frame main body 10. The fixed side 21 is provided with a clamping tongue 24 on each of the left and right sides. The clamping tongue 24 is a bent tongue, and the elastic sheet mounting position 15 is provided with a clamping hole 152 on each of the two sides of the lower part, and the clamping tongue 24 can be clamped into the clamping hole 152, thereby limiting the elastic sheet 20.

[0051] The fixed side 21 is also provided with a second fixing structure 25, which is a fixed clamping hole. The elastic sheet mounting position 15 is provided with a fixed boss 153, and the second fixing structure 25 is used to be clamped with the fixed boss 153, thereby forming a firm limit for the elastic sheet 20 on the elastic sheet mounting position 15 on the basis of the cooperation of the clamping tongue 24 and the clamping hole 152.

[0052] The connecting section 28 is further arranged between the fixed side 21 and the transition section 22, and the connecting section 28 is arranged at an angle relative to the fixed side 21 and the transition section 22, thereby having a bending process angle A relative to the transition section 22, which is greater than 0 degrees, compared with the flat state between the fixed side 21 and the transition section 22. When the elastic sheet 20 is mounted on the elastic sheet mounting position 15, the pre-tightening force of the elastic sheet 20 can be increased, so that the elastic sheet 20 can more stably fix the connector module 2 in the inner cavity 16 of the frame main body 10.

[0053] The assembly steps of the frame main body 10 and the elastic sheet 20 are as follows:

[0054] The fixed side 21 of the elastic sheet 20 is loaded from the bottom of the frame body 10, and then the elastic sheet 20 is pushed to the top of the frame body 10 to the clamping tongue 24 of the elastic sheet 20 is clamped into the clamping port 152, and the second fixing structure 25 is clamped with the fixing boss 153, and the assembly of the frame body 10 and the elastic sheet 20 is completed.

[0055] The mounting steps of the connector module 2 are as follows:

[0056] 1. The connector module 2 is aligned with the mounting position of the connector module 2 in the inner cavity 16;

[0057] 2. The connector module 2 is pressed into the mounting frame 1, and the hanging table 201 of the connector module 2 is opened by the slope of the upper edge 271 of the first fixing structure 27 of the elastic sheet 20;

[0058] 3. Continue to press the connector module 2 into the mounting frame 1, and when a "click" sound is heard, the connector module 2 is installed in place, the elastic sheet 20 automatically rebounds, the first fixing structure 27 of the elastic sheet 20 buckles the hanging table 201 on both sides of the connector module 2, and the installation is completed.

[0059] The disassembly steps of the connector module are as follows:

[0060] 1. The assembly of the connector module 2 and the mounting frame 1 is taken out;

[0061] 2. The elastic sheet 20 on both sides of the mounting frame 1 is simultaneously turned outward to the limiting tongue 26 of the elastic sheet 20 in contact with the elastic sheet limiting rib 151 of the frame body 10, so that the elastic sheet 20 is in a forced opening state, at this time the first fixing structure 27 of the elastic sheet 20 is separated from the hanging table 201 of the connector module 2, the connector module 2 is pushed upward, and the connector module 2 is separated from the mounting frame 1, and the disassembly is completed.
