Abstract
The utility model discloses a butterfly spring connector, which mainly comprises plug pins, a pressing line frame and a leaf spring and is characterized in that curves are added on both two '<'-shaped wings, a small tongue piece facing to the inner side is arranged on the leaf spring in the middle of the inner side of the pressing line frame, and a slantingly-upward inclined groove with the angle smaller than 90 degrees is arranged at the bottom of the pressing line frame. By enlarging clamping force and pulling-out force on leads and friction force between the leaf spring and the leads generated by deformation of the leaf spring, the butterfly spring connector reduces a compression stroke of an operation button during wiring, adjusts pressing line angles of the leaf spring, and can avoid overpressure of the leaf spring and improve mechanical reliability of connection.
Description
Technical field
The utility model relates to a kind of assembly structure of spring connector, especially design a kind of can Fast Installation, be connected firmly, safe and reliable connector package assembly.
Background technology
As shown in Figure 1, relevant traditional butterfly spring connects, and metalwork is made up of three parts; Be pin, pressing line frame and steel sheet spring, three parts are through two solder joints of spot welding formation are fixed together at the top, and spring steel plate roughly is " ∠ " shape; The both wings of " ∠ " shape all are straight linear structure; Usually do not have setback,, be pressed with groove in the bottom of pressing line frame to increase friction in order to strengthen friction and the withdrawal force between pressing line frame and lead.
Summary of the invention
Defective in view of above-mentioned prior art existence; The purpose of the utility model is to propose a kind of butterfly spring connector; Limited in the space, especially under the very big situation of short transverse limit, to improve clamping and the withdrawal force problem less than normal that there is lead in traditional structure; For clamping and the withdrawal force that increases lead, therefore traditional butterfly spring structure has been carried out design again.
The purpose of the utility model will be achieved through following technical scheme:
A kind of butterfly spring connector designs the shape of steel sheet spring again, and the both wings " ∠ " shape all increase bending respectively, to increase chucking power and the withdrawal force to lead that the steel sheet spring distortion is produced; Operate on simultaneously the opening of mouthful shape, to increase the frictional force with lead in the pressing line frame bottom.
In addition; One side of pressing close to pressing line frame at steel sheet spring increases by one to the inboard bending of pressing line frame; Also be the shape that diminishes gradually on the steel sheet spring width; Stress concentration point is dispersed and arranges when making the steel sheet spring distortion, thereby the bigger compression ratio of steel sheet spring realization, thereby increases clamping and the withdrawal force of steel sheet spring to lead.
Secondly, in recessed bending to clamping lead direction of side increase of steel sheet spring clamping lead, the compression travel of action button in the time of can reducing wiring is adjusted steel sheet spring line ball angle simultaneously, and then improves the withdrawal force of lead.
Once more, the middle part inboard at pressing line frame has a tab to the inside, as the stop bit of steel sheet spring, to prevent the steel sheet spring overvoltage.
At last, have oblique slot obliquely in the bottom of pressing line frame, thereby the frictional force of can increase lead and extract the time and pressing line frame bottom improves the Mechanical Reliability that connects less than an angle of 90 degrees.
The application of the utility model structure, its outstanding effect shows as: through the optimization deformation design of steel sheet spring and pressing line frame structure thereof, make steel sheet spring to obtain the bigger chucking power to lead with less distortion, thereby promote the lead withdrawal force.According to experiment test, can be implemented in the space of 6mm thickness, realize lead withdrawal force, thereby realize big clamping in little space and withdrawal force requirement greater than 100N, satisfy the occasion of high density wiring of Industry Control connection area and high reliability request.
Simultaneously, because package assembly, can effectively realize Fast Installation, saving cost through rationally improving, security reliability, withstand voltage properties strengthens, and effect is remarkable.
Below in conjunction with the embodiment accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is relevant traditional butterfly spring connector sketch map;
Fig. 2 is the perspective view of the utility model decomposing state;
Fig. 3 is the side-looking structural representation of the utility model decomposing state.
Embodiment
As shown in Figures 2 and 3, be a kind of butterfly spring connector that the utility model proposes, its pin 1 by copper alloy, pressing line frame 2 and steel matter springs 3 are formed, and design again in the shape to spring, and the both wings " ∠ " shape all increase bending respectively.From feature structure: the side that said butterfly spring connector is pressed close to pressing line frame at steel sheet spring increases by one to the inboard bending of pressing line frame, and its side at steel sheet spring clamping lead increases a recessed bending to clamping lead direction.This shows that this package assembly need not to use screw fastener, pressing line frame 2 and steel sheet spring 3 location that can cooperatively interact, structural design simplifies more, firmly, be prone to assembling, be prone to the formation standardized production, reduced the technology cost.
Say further; One side of pressing close to pressing line frame 2 at steel sheet spring increases a bending to pressing line frame 2 inboards; Also be the shape that diminishes gradually on steel sheet spring 3 width; Stress concentration point is dispersed and arranges when making steel sheet spring 3 distortion, thereby the bigger compression ratio of steel sheet spring 3 realizations, thereby increases the chucking power of 3 pairs of leads of steel sheet spring.
Say that further in recessed bending to clamping lead direction of side increase of steel sheet spring 3 clamping leads, the compression travel of action button in the time of can reducing wiring is adjusted steel sheet spring 3 line ball angles simultaneously, and then improves the withdrawal force of lead.
Say further that again the middle part inboard at steel sheet spring 3 pressing line frames has a tab 4 to the inside, as the stop bit of steel sheet spring 3, to prevent steel sheet spring 3 overvoltages.
In addition, have oblique slot obliquely 5 in the bottom of pressing line frame 2, thereby the frictional force of can increase lead and extract the time and pressing line frame 2 bottoms has good spline effect, improves the Mechanical Reliability that connects less than an angle of 90 degrees.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
