Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a connector with a snap-fit ​​mechanism for a switch. Background Technology

[0002] A connector is a device that indirectly connects one object to another. Switch connectors are used to connect switch-related equipment. Rotary switches are very common in household appliances such as water heaters, fans, and microwave ovens. The knob of a rotary switch is connected to the rotating post of the switch body to realize the function of operating the switch by turning the knob. However, the connection method between the knob and the rotating post of the switch body in existing rotary switches is mostly to make a hole in the knob and press it into the end of the rotating post. This causes the knob to easily separate from the rotating post when the switch is in use, which affects the normal use of the switch. Utility Model Content

[0003] The purpose of this invention is to provide a switch with a snap-fit ​​connector, which can effectively improve the stability of the connection between the knob and the rotating post, and prevent the knob from falling off the end of the rotating post and affecting the normal use of the switch.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A switch connector with a snap-fit ​​includes a rotating column, the front end of which is fixedly connected to the rear end of a connecting block. The front end of the connecting block is fitted inside a boss, and the front end of the boss is fixedly connected to the inner front side of a knob. A second screw hole is provided in the middle of the front side of the connecting block, and the second screw hole is threadedly connected to the rear end of a connecting bolt. The connecting bolt is also threadedly connected to a first screw hole, which is located on the inner front side of the knob.

[0006] The front end of the connecting bolt is fitted into a recessed hole, which is located on the front side of the knob and is in continuous communication with the screw hole.

[0007] A positioning groove is provided on the inner side of the upper side of the protrusion. The positioning groove is sleeved with the positioning block. The bottom end of the positioning block is fixedly connected to the upper surface of the connecting block. The cross-section of the positioning block and the positioning groove are both trapezoidal.

[0008] The rotating column is fitted inside the sleeve hole, which is located in the middle of the support plate.

[0009] The outer side of the support plate is fixedly connected to one end of each of the four connecting seats, and the other end of each of the four connecting seats is provided with a screw hole.

[0010] The four screw holes are respectively threaded to one end of the four fixing bolts.

[0011] A limiting ring groove is formed in the sleeve hole, and multiple balls are sleeved in the limiting ring groove.

[0012] Each of the aforementioned balls also engages with an annular groove, which is formed on the outer surface of the rotating column.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model improves the stability of the connection between the knob and the rotating column by providing a second screw hole on the front side of the connecting block and a recessed hole and a first screw hole in the knob, and connecting the connecting bolt to the first and second screw holes. This prevents the knob from separating from the rotating column during use and affecting the normal operation of the switch. Furthermore, by setting a positioning block and positioning groove with an interference fit, the stability of the connection between the knob and the connecting block and rotating column can be further improved.

[0015] This invention features a support plate with a sleeve hole for connecting to a rotating column. A limiting groove is formed within the sleeve hole, and an annular groove is formed on the rotating column. Multiple ball bearings are positioned between the annular groove and the limiting groove. This design utilizes the support plate and the ball bearings to support and limit the rotation of the rotating column, thereby improving its stability. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, a switch with a snap-fit ​​connector includes a rotating column 1. The front end of the rotating column 1 is fixedly connected to the rear end of the connecting block 12. The front end of the connecting block 12 is sleeved in the boss 8. The front end of the boss 8 is fixedly connected to the inner front side of the knob 5. A second screw hole 13 is provided in the middle of the front side of the connecting block 12. The second screw hole 13 is threadedly connected to the rear end of the connecting bolt 7. The connecting bolt 7 is also threadedly connected to a first screw hole 9. The first screw hole 9 is provided on the inner front side of the knob 5.

[0024] Furthermore, the front end of the connecting bolt 7 is fitted into the recessed hole 6, which is located on the front side of the knob 5 and communicates with the screw hole 9. By providing a screw hole 13 on the front side of the connecting block 12 and providing a recessed hole 6 and a screw hole 9 in the knob 5, the connecting bolt 7 is connected to the screw hole 9 and the screw hole 13, thereby effectively improving the stability of the connection between the knob 5 and the rotating column 1 and preventing the knob 5 from separating from the rotating column 1 during use, which would affect the normal use of the switch.

[0025] Furthermore, a positioning groove 10 is provided on the inner side of the upper side of the boss 8. The positioning groove 10 is sleeved with the positioning block 14. The bottom end of the positioning block 14 is fixedly connected to the upper surface of the connecting block 12. The cross-sections of the positioning block 14 and the positioning groove 10 are both trapezoidal. By setting the positioning block 14 and the positioning groove 10 to be interference-fitted, the stability of the connection between the knob 5 and the connecting block 12 and the rotating column 1 can be further improved.

[0026] Furthermore, the rotating column 1 is fitted inside the sleeve hole 16, which is located in the middle of the support plate 4.

[0027] Furthermore, the outer side of the support plate 4 is fixedly connected to one end of each of the four connecting seats 3, and the other end of each of the four connecting seats 3 is provided with a screw hole 15.

[0028] Furthermore, the four screw holes 315 are respectively threaded to one end of the four fixing bolts 2.

[0029] Furthermore, a limiting annular groove 17 is formed in the sleeve hole 16, and multiple balls 18 are sleeved in the limiting annular groove 17. By forming a sleeve hole 16 in the support plate 4 to connect with the rotating column 1, and by forming a limiting annular groove 17 in the sleeve hole 16 and an annular groove 11 on the rotating column 1, and by setting multiple balls 18 between the annular groove 11 and the limiting annular groove 17, the support plate 4 and multiple balls 18 are used to support and limit the rotating column 1, thereby further improving the stability of the rotation of the rotating column 1.

[0030] Furthermore, each of the multiple balls 18 also overlaps with the annular groove 11, which is formed on the outer surface of the rotating column 1.

[0031] The working principle of this utility model is as follows: When installing this device, multiple fixing bolts 2 can be used to connect the connecting seat 3 to the switch housing to support the support plate 4, and the boss 8 can be inserted into the front end of the connecting block 12, and the positioning block 14 can be snapped into the positioning groove 10. At this time, the user can connect the connecting bolt 7 to the screw hole 9 and the screw hole 13 to further fix the knob 5 to the connecting block 12, and make the front end of the connecting bolt 7 fit into the concave hole 6. When operating the switch, the user can rotate the knob 5 to drive the rotating column 1 to rotate and control the operation of the switch.

[0032] The above description is merely a preferred embodiment of this utility model.
