The application is described in further detail below with reference to the drawings.

The embodiment of the application discloses a spring plate assembly.

As shown in fig. 1, 2 and 3, an elastic piece assembly comprises an elastic piece 1, a fixed plate 2, a fixed bottom plate 3 and two bottom plate retaining walls 4, wherein the fixed bottom plate 3 is arranged opposite to the fixed plate 2; a contact gap exists between the fixed plate 2 and the bottom plate retaining wall 4; the two bottom plate retaining walls 4 are oppositely arranged on one side, facing the contact gap, of the fixed bottom plate 3; the elastic sheet 1 is arranged between the two bottom plate retaining walls 4; the elastic sheet 1 comprises a contact portion 11 and a buffer portion 12, at least two contact portions 11 are arranged, at least one buffer portion 12 is arranged, the contact portions 11 and the buffer portions 12 are alternately arranged, and the contact portions 11 extend into the contact gaps.

The shell fragment 1 sets up between two bottom plate barricades 4, when plug device inserts in the contact gap, plug device can with contact 11 butt, along with the plug device's inserts, thereby contact 11 can be extruded and take place elastic deformation, because contact 11 with buffer 12 sets up in turn for contact 11 has at least one buffer 12 to provide elastic restoring force, makes shell fragment 1 whole have high elastic characteristics, makes plug device can be compressed tightly by the elastic restoring force butt of shell fragment 1 after inserting, improves plug device male steadiness. The contact portion 11 is provided with at least two contact areas, so that the contact area between the plug device and the elastic sheet 1 can be increased, the pressure from the elastic sheet 1 received by the plug device is dispersed, the stress concentration received by the plug device is reduced, and the service life of the plug device is prolonged.

Specifically, the contact portion 11 and the buffer portion 12 are curved arcs, and the number of the contact portion 11 and the buffer portion 12 is adapted to the mounting position according to the actual situation. In a preferred embodiment, two contact portions 11 are provided, one buffer portion 12 is provided, the buffer portion 12 is provided between the two contact portions 11, and the buffer portion 12 connects the two contact portions 11. The elastic sheet 1 is of an inverted W shape as a whole. When the plug device is inserted, the plug device contacts the two contact portions 11 and presses the two contact portions 11. The two contact portions 11 are pressed and then opened to two sides, and at this time, the buffer portion 12 located between the two contact portions 11 buffers the pressure applied to the contact portions 11 and applies an elastic restoring force to the contact portions 11, so that the plugging device can always abut against the contact portions 11 to ensure good contact.

The shape of the fixing plate 2 and the shape of the fixing bottom plate 3 are rectangular as a whole. The shape of the floor retaining wall 4 is also rectangular. The length of the elastic sheet 1 and the bending radian of the contact part 11 and the buffer part 12 are adapted to the distance between the two bottom plate retaining walls 4, so that two ends of the elastic sheet 1 can be respectively abutted with the bottom plate retaining walls 4.

There is a certain distance between the bottom plate retaining wall 4 and the fixed plate 2, and the distance value between the bottom plate retaining wall 4 and the fixed plate 2 is greater than the thickness value of the plugging device, so that the plugging device can be smoothly plugged into the contact gap.

The contact portion 11 extending into the contact gap may be in contact with the fixing plate 2 or may be at a distance from the fixing plate 2. Wherein, the distance from the vertex of the contact portion 11 to the fixed plate 2 is smaller than or equal to the thickness value of the pluggable device, so that the pluggable device is prevented from being inserted into the device and loose in the insertion state, and the phenomenon of poor contact is easily generated, thereby influencing the yield of the product.

In a preferred embodiment, the distance between the apex of the contact 11 and the fixing plate 2 is between one third and two thirds of the thickness of the plug-in device. The distance cannot influence the insertion of the pluggable device due to the fact that the distance from the top point of the contact part 11 to the fixed plate 2 is too short or the contact is carried out, so that the contact area between the end part of the pluggable device and the contact part 11 is too large, and the distance from the top point of the contact part 11 to the fixed plate 2 is not too long, the elastic extrusion effect of the elastic sheet 1 on the pluggable device is not obvious, the whole insertion state is relaxed, the phenomenon of poor contact is generated, and the yield of products is influenced.

The spring sheet 1 is a beryllium copper spring sheet.

Specifically, the beryllium copper alloy spring plate has electromagnetic compatibility shielding effect, can be used for ensuring the sealing of the gap of the contact surface and increasing the reliability and service life of equipment, and has high relaxation resistance and excellent wear resistance, and can ensure the compatibility with any contact surface. And the beryllium copper elastic sheet can not burn and can not be influenced by radiation. Therefore, the beryllium copper elastic sheet is combined with the structural characteristics of the elastic sheet 1, so that the elastic sheet 1 has the characteristics of high strength, high elasticity and fatigue resistance. Meanwhile, as the pluggable device can generate larger heat when working for a long time, the beryllium copper elastic sheet has good heat conduction effect, and the good heat dissipation effect is ensured.

A buffer gap exists between the vertex of the buffer portion 12 and the fixed base plate 3.

Specifically, the buffer portion 12 does not contact the fixed base plate 3, and a certain distance exists between the vertex of the buffer portion 12 and the fixed base plate 3, so that a buffer gap is formed.

Because the inserting and pulling device is inserted into the contact gap, the elastic sheet 1 is extruded, and the elastic sheet 1 moves towards the direction close to the fixed bottom plate 3 after being stressed. A buffer gap exists between the top point of the buffer part 12 and the fixed bottom plate 3, so that a space for the elastic sheet 1 to move towards the fixed bottom plate 3 can be provided, and the insertion and the extraction of the device are convenient. If there is no buffer gap between the top of the buffer portion 12 and the fixed bottom plate 3, but the buffer portion 12 is directly contacted with the fixed bottom plate 3, when the elastic sheet 1 is extruded by the inserting and pulling device and has a trend of moving towards the fixed bottom plate 3, the elastic sheet 1 is blocked due to the supporting action of the fixed bottom plate 3, so that the elastic sheet 1 cannot move towards the direction close to the fixed bottom plate 3, the inserting and pulling device cannot be inserted, even if the inserting and pulling device is forcibly inserted into the contact gap under the condition, the elastic sheet 1 is deformed by a larger force, so that the elasticity of the elastic sheet 1 is lost, the contact between the elastic sheet 1 and the inserting and pulling device is unstable, and the phenomenon of poor contact is generated.

The elastic sheet 1 is the same as the distance from the fixed bottom plate 3 at two fixed positions of the two bottom plate retaining walls 4 respectively.

Specifically, the two ends of the elastic sheet 1 are respectively connected with the two bottom plate retaining walls 4, and the distances from the two ends, connected with the bottom plate retaining walls 4, of the elastic sheet 1 to the fixed bottom plate 3 are the same, so that the elastic sheet 1 is parallel to the fixed bottom plate 3, when the plug device is completely inserted into the contact gap, the plug device and the elastic sheet 1 are also in parallel, the contact area between the elastic sheet 1 and the plug device is increased, and the contact performance between the elastic sheet 1 and the plug device is improved, and the operation of inserting and extracting the plug device is facilitated.

In a preferred embodiment of the present application, if the spring 1 has a plurality of contact portions 11 or a plurality of buffer portions 12, when two ends of the connection between the spring 1 and the retaining wall 4 of the bottom plate are parallel to the horizontal plane, both the connection line of the vertices of the contact portions 11 and the connection line of the vertices of the buffer portions 12 are parallel to the horizontal plane.

Therefore, when the plug device is completely inserted into the contact gap, the plug device can be contacted with all the contact parts 11, so that the contact area between the plug device and the contact parts 11 is increased, and the contact property between the elastic sheet 1 and the plug device is improved.

When the plug-in device is completely inserted into the contact gap, the distances from each buffer part 12 to the fixed bottom plate 3 are the same, namely the deformation degree of each buffer part 12 is the same, so that the situation that a certain buffer part 12 is stressed and other buffer parts 12 are not stressed is avoided, the occurrence of the situation that fatigue at a certain place is increased due to stress concentration is slowed down, and the whole working life of the elastic sheet 1 is prolonged.

The distance from the fixed position of the spring plate 1 and the bottom plate retaining wall 4 to the fixed bottom plate 3 is greater than or equal to the distance from the top point of the buffer part 12 to the fixed bottom plate 3.

Specifically, if the distance from the two ends of the elastic sheet 1 to the fixed bottom plate 3 is greater than the distance from the top of the buffer portion 12 to the fixed bottom plate 3, when the elastic sheet 1 is extruded by the plugging device to make the buffer portion 12 move towards the direction close to the fixed bottom plate 3, the top of the buffer portion 12 will move continuously towards the direction close to the fixed bottom plate 3 through the horizontal height of the two end points of the elastic sheet 1. If the distance from the two ends of the elastic sheet 1 to the fixed bottom plate 3 is smaller than or equal to the distance from the top point of the buffer portion 12 to the fixed bottom plate 3, the top point of the buffer portion 12 will not pass through the horizontal height of the two end points of the elastic sheet 1 when the elastic sheet 1 is extruded by the plugging device to make the buffer portion 12 move towards the direction close to the fixed bottom plate 3.

Compared with the arrangement mode that the distance from the two ends of the spring plate 1 to the fixed bottom plate 3 is larger than or equal to the distance from the top point of the buffer part 12 to the fixed bottom plate 3, compared with the arrangement mode that the distance from the two ends of the spring plate 1 to the fixed bottom plate 3 is smaller than the distance from the top point of the buffer part 12 to the fixed bottom plate 3, the change rate of the force and the direction received by the connection part of the spring plate 1 and the bottom plate retaining wall 4 is small, the loss caused by the deformation of the spring plate 1 to the connection part of the spring plate 1 and the bottom plate retaining wall 4 can be reduced, and the service life of the spring plate 1 is prolonged.

The elastic sheet 1 and the bottom plate retaining wall 4 are fixed through heat dissipation adhesive.

Specifically, the adhesive fixing mode of the heat dissipation glue is adopted, the heat dissipation glue is gelatinous, the limitation of the shape between two objects needing to be fixed is avoided, and the heat dissipation glue has higher flexibility. And the heat-dissipating glue has a certain heat-dissipating effect. Because the heat can be generated when the plug device is used for a long time, the heat generated by the plug device can be led into the spring plate 1 because the spring plate 1 is in direct contact with the plug device, and the heat on the spring plate 1 can be led into the base plate retaining wall 4 again for heat dissipation through the heat dissipation glue in a bonding mode of the heat dissipation glue, so that the overall heat dissipation efficiency is improved.

The fixed base plate 3 is provided with heat radiation holes 31.

Specifically, the heat dissipation holes 31 are rectangular as a whole, and two heat dissipation holes 31 are formed when the two heat dissipation holes 31 are respectively bent out of the bottom plate retaining wall 4 by the fixed bottom plate 3. The two heat dissipation holes 31 are respectively arranged close to the two bottom plate retaining walls 4, and the two heat dissipation holes 31 are respectively positioned on one surface of each bottom plate retaining wall 4 far away from the other bottom plate retaining wall 4. The heat dissipation holes 31 improve the contact area between the fixed bottom plate 3 and the air, and are more beneficial to heat dissipation of the bottom plate retaining wall 4 and the fixed bottom plate 3.

The spring plates 1 are at least two, and the at least two spring plates 1 are arranged at intervals between the two bottom plate retaining walls 4.

Specifically, in this embodiment, shell fragment 1 is provided with two, and two shell fragments set up at the interval between two bottom plate barricades 4 and make there is the gap between two shell fragments 1, because the plug device during operation for a long time can produce the heat on the plug device, and the heat that produces on the plug device can be passed to on the shell fragment 1, shell fragment 1 sets up a plurality of and the interval sets up for there is the clearance between the adjacent shell fragment 1, compared with only setting up one shell fragment 1 between bottom plate barricade 4, can make shell fragment 1 have more surface area can with the air contact, has increased holistic radiating area, has improved radiating efficiency.
