Abstract
Provided is a drum-spring type elastic reliable contacting member. The drum-spring type elastic reliable contacting member comprises a pin (2) and a drum spring (1) assembled on the pin (2), the drum spring (1) is integrally an axially-opened annular structure and comprises two same open annular structures, the middle part of the drum spring (1) is circumferentially and uniformly distributed with bendable sheet-shaped structures (11), and two ends of the sheet-shaped structures are respectively connected with annular end surfaces (12). The drum-spring type elastic reliable contacting element is advantaged by reliable contact, large contact area, small contact resistance, and gentle contact force, and impacts and vibrations can be reduced; besides, a drum-spring pin is different from conventional elastic pins similar to patterns of twist pins, the drum-spring pin not only has general characteristics of elastic contacting members such as gentle plugging and reliable contact of the twist pins, but omits steps of the welding and crimping technologies etc., the assembling time of products is saved, unnecessary processes are prevented, and the drum-spring type elastic reliable contacting member has great economic and social values.
Description
Technical field
The utility model relates to contact piece structure design and applied technical field, provides especially a kind of bulging spring formula elasticity reliable contact.
Background technology
Tradition contact adopts welding, compression joint technique conventionally, and structure is more single, and is rigidly connected, and causes contact reliability not to be guaranteed.
People urgently wish to obtain the good reliable contact of bulging spring formula elasticity of a kind of technique effect.
Utility model content
Order of the present utility model is to provide the reliable contact of a kind of bulging spring formula elasticity.
The reliable contact of bulging spring formula elasticity described in the utility model, by contact pin 2 and the bulging spring 1 being assemblied on contact pin 2, formed, drum spring 1 integral body is the circulus of axially open, the middle part of drum spring 1 is circumferentially evenly distributed with flexible laminated structure 11, and the two ends of laminated structure are connected with respectively the end face 12 of ring-type;
On the contact pin 2 of described contact pin 2 and drum spring 1 contact position, be provided with annular groove I 21, drum spring 1 assembles and is fixed in the annular groove I 21 of contact pin 2 by the opening and closing of opening and the contraction of laminated structure 11, the round and smooth cone structure 22 that spring 1 enters to annular groove I 21 is roused for guiding in contact pin 2 ends near annular groove I 21, when contact pin 2 is provided with the closing in of assurance positioning sleeve with insulator contact position, drum spring contact pin can be fixed on to the annular groove II 23 with tapering in pin insulator, annular groove II 23 is connected with straight acicular texture 24.Effect is directly to insert wiring board immersed solder and connects.
Drum spring 1 is the punch forming of beryllium bronze band material, and contact pin adopts tin bronze line machine add-on type, and the surface of drum spring 1 and contact pin 2 is provided with protective layer.
Described protective layer is silver coating.
The reliable contact of bulging spring formula elasticity described in the utility model is sleeved on the overall structure that realizes contact on the contact pin of rigidity by reliable resilient contact drum spring.Not only contact is reliable, contact area is large, contact resistance is little, contact force is soft and can alleviate shock and vibration.In addition, drum spring contact pin is different from the elastic contact pin that tradition is similar to twist needle pattern, it not only has the general character that twist needle plug is soft, contact the resilient contact such as reliable, and the links such as welding procedure, compression joint technique have been saved, not only save the Product Assembly time but also avoided unnecessary operation, drum spring size also can adjust to coordinate the rigidity jack of different size as required, has larger economy and social value.
