Abstract

The utility model provides a bottom joint for a rotary electric connector. The housing is provided with annular grooves (2, 1), and the inner part of the housing is provided with conducting contact sheets (21, 11). The bottom joint for the rotary electric connector is characterized in that: the annular grooves (21, 11) are provided with draining through holes (22, 12) at the bottom position. The draining through holes (22, 12) can vertically, horizontally, or obliquely pass through the external side of the housing through draining channels (23, 13); the draining through holes (22, 12) can be independent components which are connected with the draining through holes of the annular grooves, and the draining through holes (22, 12) can be also the manufacturing components which are integrated with the annular grooves. Since the bottom of the annular grooves of the socket body is provided with a draining hole, accordingly, even if the water is splashed into the draining hole, the water can be discharged from the draining hole in time; the normal conducting work of the conducting contact sheet in the annular grooves can not be affected; accordingly, the occurrence of the current leakage and the short circuit can be effectively prevented.

Description

A kind of lower contact of rotary electric connector

Technical field

The utility model relates to a kind of rotary electric connector that is used for as separate type cordless electric appliances such as wireless electric kettle, wireless frying pan, cordless electric irons.

Background technology

In separate type electrical equipment such as existing wireless electric kettle, wireless frying pan, cordless electric iron, generally be provided with a plug body in the body bottom of electrical equipment, and a power supply pedestal that matches with it is provided with a socket, when being shelved on the electrical equipment body on the pedestal, plug body and socket plug together mutually, thereby realize the power supply to the electrical equipment body.Common, the binding post that has the right cylinder shape on the described plug body, because the restriction of its structure, described plug body, socket lay respectively at the peripheral position of electrical equipment body, power supply pedestal, the relatively center of gravity of electrical equipment body also promptly far away still patches effect from outward appearance and all therefore is affected.Chinese invention patent ZL94194173.6 number " cordless electric appliance and joint thereof " (publication number is CN1135270A) provides a kind of rotary electric connector for this reason, it comprises a male contact (being lower contact) and a cloudy receptacle terminal that engages (being top connection), described male contact comprises a center conductive post binding post, with a ring connection terminal concentric with the newel binding post, described cloudy receptacle terminal has the perforate on its front end, in order to admitting the ring connection terminal of newel binding post and described male contact, receptacle terminal has and is used for the electric contact separately that engages with the described binding post of described male contact.

But, because the socket of this rotary electric connector is arranged on the power supply pedestal, if use accidentally, in case socket is spattered with water (this seethes with excitement, is easy to when overflowing take place because of water) in the use of electric kettle by water, water will accumulate in its cannelure, make adjacent binding post cause electric leakage, short circuit by water, therefore, this safety problem needs to be resolved hurrily.

Summary of the invention

Even technical problem to be solved in the utility model provides a kind of socket to be spattered with water also unlikely by water at above-mentioned prior art present situation so electric leakage, short circuit.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the housing of the lower contact of this rotary electric connector is provided with cannelure, is provided with conductive contact blade in it, it is characterized in that described cannelure has drainage hole at bottom position.

Described drainage hole can lead to outside the housing by a drainage channel; Described drainage channel can be an individual components that is connected with the drainage hole of cannelure, also can be with cannelure be integrally manufactured, it can be vertically, level or obliquely pass outside the housing.

Described conductive contact blade can be arranged on the perisporium of cannelure vertically, also can flatly be arranged on the bottom of cannelure; For the former, described cannelure can have a darker drain groove in the inboard of conductive contact blade, and described drainage hole promptly is opened on this drain groove; For the latter, described cannelure bottom can have the local crowning position, and described conductive contact blade promptly is suspended on the described local crowning position, forms the interval thereby make between the ponding of conductive contact blade and cannelure bottom.So design is to cause electric leakage, short circuit phenomenon for the water that further prevents from time not drain as yet.

Influence for the center binding post that further is arranged in the housing centre bore is not also dabbled also is provided with the drainage channel that leads to outside the housing in the bottom of this centre bore.

Compared with prior art, the utility model is owing to have osculum in the cannelure bottom of socket, therefore, even there is water to be splashed into wherein, also can from osculum, discharge in time, do not influence the normal conduction work of conductive contact blade in the cannelure, thereby preventing to prevent effectively leaks electricity, the generation of short circuit.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, be embodiment one of the present utility model, the lower contact housing of this rotary electric connector is provided with a centre bore 3 and two

concentric cannelures

2,1, be respectively arranged with center binding post 31,

conductive contact blade

21,11 in it, described

cannelure

2,1 has respectively

drainage hole
