Description

Technical Field

[0001] The present invention relates to the field of electric connectors, in particular to an electric connector and a base. Background Art

[0002] As shown in the Chinese patent application number CN202321507839.5, "A Coupler," its main structure includes a coupling lower seat and a load-bearing cover disposed on the outer periphery of the coupling lower seat and sharing the load with the coupling lower seat. When the weight borne by the load-bearing cover equals or exceeds a preset pressure value, the load-bearing cover and the coupling lower seat sink, triggering the element to stop adding water. During assembly, the load-bearing cover is suspended above the glass panel, forming a longitudinal gap between the glass panel and the load-bearing cover to allow for the load-bearing cover to sink. This gap, which is approximately 5 mm wide, can easily cause foreign objects such as toothpicks to roll along the surface of the glass panel into the longitudinal gap during use, causing the load-bearing cover to become stuck and unable to press down normally. This results in the kettle's weight-dependent function of stopping water from failing, and the entire structure is unsightly. Therefore, the applicant has provided a new solution to the above-mentioned prior art problems through structural improvements and enhancements, which is available for consumers to choose.

[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] First embodiment:

[0024] like Figures 1 to 4 As shown, an electrical connector includes a fixed base 1 and a coupling base 2, the coupling base 2 is provided with a conductive circuit 3 and is movably connected above the fixed base 1, the coupling base 2 is provided with a load-bearing cover 4 along its outer periphery for bearing weight, the fixed base 1 is connected to a lower base component placed below the load-bearing cover 4 and used for assembly and connection with the mounting panel 15, the lower base component is provided with a concave disc cavity 501, and the load-bearing cover 4 is movably sunk in the concave disc cavity 501 at least at its outer periphery, and a relative inner and outer clearance is formed between the outer periphery and the cavity wall of the concave disc cavity 501.

[0025] This type of electrical connector prevents the stress-bearing cover 4 from being suspended above the mounting panel 15, thereby preventing the gap below the stress-bearing cover 4 from being radially open. This prevents foreign objects such as toothpicks from falling into the gap between the two along the surface of the mounting panel 15, causing the stress-bearing cover 4 to be stuck, resulting in the stress-bearing cover 4 being unable to be pressed down to work normally. In addition, the electrical connector of this structure is more beautiful and practical.

[0026] The lower seat assembly includes a lower seat cover 51 and a lower seat frame 52. The concave disc cavity 501 is arranged on the lower seat cover 51, and an outer flange 511 extends around the periphery of the lower seat cover 51. The lower seat frame 52 is connected to the bottom of the lower seat cover 51 and is fastened to the fixed seat 1 to clamp the mounting panel 15 between the outer flange 511 and the lower seat frame 52; the lower seat cover 51 is used to support the fixed seat 1 and the coupling seat 2, and is placed on the mounting panel 15. The lower seat cover 51 is movably connected to the fixed seat 1, and the lower seat cover 51 and the lower seat frame 52 can adapt to various thicknesses of the mounting panel 15.

[0027] A sealing groove 512 is provided at the bottom of the outer flange 511, and a sealing ring 6 is provided in the sealing groove 512. The sealing ring 6 elastically abuts against the upper surface of the mounting panel 15; it is used to seal the gap between the lower seat cover 51 and the mounting panel 15 to prevent liquid from penetrating into the electrical connector through the gap.

[0028] A plurality of drainage holes 513 are provided on the circumferential surface of the lower seat cover 51, and the side of the cover surface away from the drainage holes 513 is inclined downward in the direction of the drainage holes 513; in this embodiment, each drainage hole 513 is arranged close to the inner side of the lower seat cover 51, and the outer side of the lower seat cover 51 is inclined inwardly, with an inclination angle of about 1°, so that the liquid drips onto the cover surface through the gap between the force-bearing cover 4 and the lower seat cover 51, and can be guided to the drainage holes 513, and finally discharged to the bottom of the electrical connector through the drainage holes 513.

[0029] The load-bearing cover 4 is detachably connected to the coupling seat 2 through a first connecting component; the lower seat frame 52 is detachably connected to the fixed seat 1 through a second connecting component; the load-bearing cover 4 and the lower seat cover 51 can be replaced with different colors, patterns, and materials according to different needs, so that the load-bearing cover 4 and the lower seat cover 51 play a decorative role.

[0030] An elastic reset structure is also provided between the fixing seat 1 and the coupling seat 2. The force-bearing cover 4 is connected to the fixing seat 1 by floating up and down along with the coupling seat 2 through the elastic reset structure; when the water level in the kettle body drops or is emptied, the coupling seat 2 is reset by the elastic reset structure.

[0031] In addition, the fixing base 1 is provided with a pressure switch 9 for being connected in series with the water supply circuit, and the coupling base 2 is provided with a switch trigger body 10 that floats up and down with it. When the weight carried by the stress cover 4 is equal to or exceeds the preset pressure value, the stress cover 4 drives the coupling base 2 to sink, and the switch trigger body 10 triggers the pressure switch 9 to disconnect the water supply circuit; the maximum water level in the kettle body is controlled by the pressure switch 9 in a weight-triggered manner, so that the electric kettle meets safety requirements.

[0032] The pressure switch 9 can be a micro switch, a moving contact piece, a pressure sensor or the like.

The reinforcing ribs 525 can increase the strength of the connecting ribs 523. When the outer support ring 522 is under pressure, the connecting ribs 523 are not easily broken by the force acting on them.

[0036] A plurality of connecting ears 524 with connecting holes extend from the inner side of the inner fixing ring 521, and connecting bosses 12 are provided on the fixing seat 1 corresponding to the connecting holes. The connecting ears 524 and the connecting bosses 12 constitute a second connecting component, and the lower seat frame 52 is assembled and connected to the fixing seat 1 by passing the fastening unit through the connecting holes and the connecting bosses 12.
