Abstract

The utility model relates to a design relating to a connector, particularly a structure which is used for a rotary connector. The connector mainly comprises a bottom cover, a circuit board which is linked with an external connection motor, and an upper cover in which terminal sets are arranged, wherein the circuit board is contained between the bottom cover and the upper cover, the circuit board can rotate inside the bottom cover and the upper cover, and the upper cover is inlaid on the upper end of the bottom cover and can perform the proper angular rotation on the bottom cover. When the whole connector is sheathed on the motor shaft center, the terminal sets can perform a proper angular rotation on the bottom cover by the upper cover; thus, a contact angle between the terminal sets and the circuit board can be corrected so as to achieve the requirement of electric conduction balance when the terminal sets and the circuit board are electrically conducted.

Description

The rotating connectors structure

Technical field

The utility model is a kind of design relevant with connector, refers to a kind of structure that is applied to rotary connector especially.

Background technology

General rotating connectors constitute a complete workflow with array mostly on using, to reach a complete moving line, therefore respectively organize accurate that collocation between rotating connectors must be suitable.

Yet, general rotating connectors, it mainly is the outside, axle center that is sheathed on an external motor, and rotating connectors inside is provided with a circuit board, this circuit board and axle center of motor interlock, rotating connectors inside one is provided with terminal group simultaneously, and terminal group one end is convexly set in the rotating connectors outside, and an end contacts with circuit board in rotating connectors are inner.

But, the terminal group of tradition rotating connectors inside establishes build-in on rotating connectors, when the axle center of circuit board and motor produces interlock, because the axle center of motor and the axis hole of circuit board are easy to generate tolerance, thereby cause eccentric phenomenon, therefore when carry out current lead-through between circuit board and terminal group, cause easily to contact the generation deviation between terminal group and circuit board, make current lead-through produce error, thereby influence having some setbacks in the whole rotating connectors action.

Therefore arrange in pairs or groups together when using when many group rotating connectors, if during a little error of generation, will have a strong impact on the deviation of overall workflow between each rotating connectors.

Therefore, the inventor is in view of above-mentioned variety of problems, so plentiful and substantial experiences such as the long-pending research of being engaged in this product for many years, design, manufacturing actively drop into a large amount of painstaking effort and energy and are ground wound, success finally develop rotating connectors structure of the present utility model.

Bottom one side is provided with a groove, and loam cake one side convexes with a flange with respect to the groove position of bottom, and the basal area of flange is slightly less than the basal area of groove, to be placed on the rotational angle in the accommodation space in the restriction.

Flange slightly is convexly set in the bottom outside.

Bottom one side is provided with a projection, loam cake one side then be provided with one with the corresponding caulking groove of projection, and the width of caulking groove is slightly larger than projection, to be placed on the rotational angle in the accommodation space in the restriction.

The boss bottom further is provided with engaging tooth, and the accommodation space upper surface is provided with corresponding engagement projection, produces the locating effect of translation-angle by engaging tooth and engagement projection.

Embodiment

The structure of the utility model rotating connectors structures is formed, and sees also Figure 1 and Figure 2, and these rotating connectors can be made of for the loam cake 30 of terminal group 40 settings with the circuit board 20 and of external motor interlock a bottom 10,, wherein:

These bottom 10 upper ends have an accommodation space 11, accommodation space 11 bottoms are provided with a storage tank 12, and the sidewall of accommodation space 11 is provided with most the clipping blocks 13 that protrude, and these bottom 10 1 sides are provided with a groove 14 simultaneously, and the corresponding side of groove 14 is provided with a projection 15.

This circuit board 20 is arranged at storage tank 12 inside, and its circuit board 20 is provided with an axis hole 21, and on the axle center that is arranged in an external motor, the axle center generation interlock with motor makes circuit board 20 be able to rotate in driven by axle center of motor in storage tank 12.

This loam cake 30 is located on the accommodation space 11 of bottom 10, and these loam cake 30 inside are embedded with terminal group 40, terminal group 40 1 ends are convexly set in loam cake 30 outsides, the other end is then in circuit board 20 contacts, and these loam cake 30 bottoms convex with the boss 31 of ring-type, and loam cake 30 1 sides convex with a flange 32 with respect to groove 14 positions of bottom 10, flange 32 slightly is convexly set in bottom 20 outsides, the basal area of flange 32 is smaller than the basal area of groove, side with respect to flange 32, then be provided with one with projection 15 corresponding caulking grooves 33, the width of caulking groove 33 is bigger than projection 15.

The storage tank 12 that is embedded at bottom 10 in regular turn when circuit board 20 and loam cake 30 is during with accommodation space 11, make the clipping block 13 that is convexly equipped with on accommodation space 11 sidewalls, clip is on the boss 31 of loam cake 30, this flange 32 is located on the groove 14 simultaneously, and caulking groove 33 is embedded at projection 15 lower ends, and then this loam cake 30 is able in the movable accommodation space that is arranged at bottom 10 11.

Because this loam cake 30 is subjected to clipping block 13 clips on boss 31, therefore make loam cake 30 be able to the effect that in the accommodation space 11 of bottom 10, rotates; Moreover because the basal area of flange 32 is smaller than the basal area of groove 14, and the width of caulking groove 33 is bigger than projection 15, thereby limits the angle that loam cake 30 rotates on accommodation space 11.

Thereby, be sheathed on the outside, axle center of motor when the utility model, when making the axle center generation interlock of circuit board 20 and motor, even the axis hole of circuit board 20 21 produces eccentric with the axle center of motor, also can carry out the adjustment of loam cake 30 angles, as shown in Figures 3 and 4, and then proofread and correct the contact angle of 20 of terminal group 40 and circuit boards by the flange 32 that is convexly set in bottom 10 outsides, when making terminal group 40 and circuit board 20 carry out current lead-through, reached the requirement of conduction balance.

In addition, as Fig. 2 and shown in Figure 5, wherein on the contact-making surface of boss 31 bottoms of loam cake 30 and accommodation space 11, further be provided with corresponding engaging tooth 34 and engagement projection 16; Therefore, when loam cake 30 carries out the adjustment of angle in accommodation space 11, be able to produce the locating effect of translation-angle by engaging tooth 34 and engagement projection 16, can avoid simultaneously loam cake 30 in accommodation space 11, to produce the phenomenon of rotating voluntarily, and then make the use of whole rotating connectors have more efficient.

Though the utility model discloses with specific embodiment; but it is not in order to limit the utility model; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.
