Abstract
The utility model discloses a multi-section elastic contact finger crown spring for a large-current connector, which comprises a plurality of end rings and an intermediate ring, wherein the end rings are fixed at the end parts of a laminating assembly, the laminating assembly is laminated with a plug-in unit, and the intermediate ring is fixed between the laminating assembly and the laminating assembly; the middle ring is provided with a breaking groove which is convenient for the middle ring to break, the breaking groove is added, the crown spring can be broken as required more conveniently, and the crown spring cannot deform after being broken.
Description
Technical Field
The utility model discloses hat spring technical field especially relates to a be used for heavy current connector multisection elastic contact to indicate hat spring.
Background
The crown spring is stable due to low contact resistance, small insertion force, low contact abrasion, long insertion and extraction service life, and in a strong vibration impact environment, high reliability capable of keeping electric contact can be used for large current transmission, a power transmission interface used for an electric automobile and the like is established, and in order to increase the contact area of the crown spring and a plug-in unit, the crown spring is evolved into a plurality of crown springs from an initial single-section crown spring, such as the application number: the patent of cn201621300916.x discloses a connecting piece of a crown spring jack, wherein the crown spring jack comprises a plurality of annular substrates and a plurality of spring groups, the annular substrates are of an integral structure, when the connecting piece is used, because the crown spring is too long, the cutting needs the help of a tool, and the crown spring is easy to scrap after the cutting, which causes waste.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the technical problem to be solved in the present invention is to provide a multi-section elastic contact finger crown spring for a high-current connector, so as to solve the above problems.
To achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a pair of be used for heavy current connector multisection elasticity to touch finger crown spring, its characterized in that: the joint component comprises a plurality of joint components jointed with the plug-in units, end rings fixed at the ends of the joint components and an intermediate ring fixed between the joint components and the joint components; the middle ring is provided with a breaking groove which is convenient for the middle ring to break; the laminating subassembly includes a plurality of arc shell fragment.
Furthermore, the arc-shaped elastic sheets are uniformly fixed around the end rings and the middle ring to form a waist drum shape.
Furthermore, the end ring and the intermediate ring are both of circular ring structures, and a gap is formed in the middle of the end ring and the intermediate ring.
Further, the end ring and the intermediate ring have the same radius.
Further, the joint assembly, the end rings and the intermediate ring are of an integral structure.
The utility model has the advantages that:
a multi-section elastic contact finger crown spring for a high-current connector is provided with a plurality of attaching assemblies attached to plug-in units, end rings fixed at the ends of the attaching assemblies and an intermediate ring fixed between the attaching assemblies and the attaching assemblies; the middle ring is provided with a breaking groove which is convenient for breaking the middle ring, so that the crown spring can be broken along the breaking groove when the length of the crown spring is too long, and the broken crown spring still has an integral structure, so that the shape of the crown spring is effectively prevented from being changed when the crown spring is broken, and the resource waste is avoided.
Drawings
Fig. 1 is a schematic view of the overall structure of a multi-section elastic contact finger crown spring for a high-current connector according to the present invention.
Reference numbers in the figures:
1. fitting the assembly; 2. an end ring; 3. an intermediate ring; 4. breaking the groove; 5. an arc-shaped elastic sheet.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1, the multi-section elastic contact finger crown spring for a high-current connector provided in this embodiment is characterized in that: the end ring 2 is fixed at the end part of the attaching component 1 and the middle ring 3 is fixed between the attaching component 1 and the attaching component 1; the middle ring 3 is provided with a breaking groove 4 which is convenient for the middle ring 3 to break; the attaching assembly 1 comprises a plurality of arc-shaped elastic pieces 5.
Further, the arc-shaped elastic sheets 5 are uniformly fixed around the end ring 2 and the middle ring 3 to form a waist drum shape; when the plug-in unit is inserted into the crown spring, the arc-shaped elastic sheet 5 can be tightly attached to the plug-in unit.
Further, the end ring 2 and the intermediate ring 3 are both of circular ring structures; the end ring 2 and the intermediate ring 3 are arranged in a circular ring structure, and a gap from the upper end ring to the lower end ring is formed, so that a crown spring can be conveniently installed into the jack and can be in elastic contact when a contact pin is inserted.
Further, the end ring 2 and the intermediate ring 3 have the same radius.
Further, the joint assembly 1, the end ring 2 and the intermediate ring 3 are of an integral structure, so that the crown spring is prevented from generating heat due to the resistance value change at the joint when a large current flows.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
