Abstract

The utility model provides a take multistage connector of strong and weak electric interface two-way fool-proofing structure, includes the main casing body of connector, installs in the main casing body and the external a plurality of forceful electric power wide binding post and the narrow binding post of weak electricity of pegging graft, the main casing body on be equipped with the storage tank of the narrow binding post of the weak electricity of holding, be equipped with on the inner wall about the storage tank and separate the muscle to at the terminal spacing door of formation of storage tank, the width of spacing door is less than the width of the wide binding post of forceful electric power, the width of spacing door is. The external plug connector corresponding to the strong-current wide wiring terminal can not extend into the limit door, the situation that the strong-current plug connector is inserted into the weak-current wiring terminal is effectively avoided, and the narrow weak-current wiring terminal plug connector cannot be successfully plugged with the wide strong-current wiring terminal even if the narrow weak-current wiring terminal plug connector enters the wide strong-current wiring terminal channel because the width of the narrow weak-current wiring terminal plug connector is smaller than that of the wide strong-current wiring. Thereby realizing the two-way fool-proofing of strong current and weak current.

Description

Multi-stage connector with strong and weak electrical interface bidirectional fool-proof structure

Technical Field

The utility model relates to an electricity tea set connector especially relates to a fool-proof structure of electricity connection.

Background

Along with the social development and the progress of science and technology, the functions of the existing electric tea set are more and more, particularly, a multi-stage connector is adopted, the realization of the functions needs weak current transmission, a plurality of strong current wiring terminals and weak current wiring terminals can be formed in the multi-stage connector, even if the strong current wiring terminals are wide wiring terminals, the weak current wiring terminals adopt relatively narrow wiring terminals, and the assembly personnel still can easily perform misplug, namely, the wide plug connector which is spliced with the wide wiring terminals is misplug on the weak current wiring terminals, and the plugging part can also be plugged during the plugging process because the width of the plugging part is larger than that of the weak current wiring terminals, so that the operation causes damage to the multi-stage connector, and even seriously damages the controller to cause the complete machine.

Disclosure of Invention

An object of the utility model is to provide a simple structure, easily realize, have two-way multistage connector who prevents slow-witted structure to the defect that prior art exists.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a take multistage connector of strong and weak electric interface two-way fool-proofing structure, includes the main casing body of connector, installs in the main casing body and the external a plurality of forceful electric power wide binding post and the narrow binding post of weak electricity of pegging graft, the main casing body on be equipped with the storage tank of the narrow binding post of the weak electricity of holding, be equipped with on the inner wall about the storage tank and separate the muscle to at the terminal spacing door of formation of storage tank, the width of spacing door is less than the width of the wide binding post of forceful electric power, the width of spacing door is.

As an improvement: the spacing ribs on the left inner wall and the right inner wall of the accommodating groove are symmetrically arranged, and the distance between the spacing door formed by the spacing ribs and the tail end of the weak current narrow wiring terminal is smaller than the length of the butt joint part of the plug connector spliced with the spacing door.

The utility model discloses a set up in the main casing body and separate the muscle in the narrow binding post's of the weak current of holding storage tank, thereby form the spacing door that the width is less than the wide binding post width of forceful electric power on the connector, make the external plug connector that corresponds with the wide binding post of forceful electric power can't stretch into spacing door, effectively avoid the condition that the forceful electric power plug connector inserted weak current binding post, moreover narrow weak current binding post's plug connector is because width itself is less than wide forceful electric power binding post, even admittedly, get into wide forceful electric power binding post passageway also can. Thereby realizing the two-way fool-proofing of strong current and weak current. And this design simple structure can improve the security in electric tea set connector field greatly, convenient assembly.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of a multi-stage connector with a strong and weak electrical interface bidirectional fool-proof structure according to the present invention.

Detailed Description

As shown in fig. 1, the embodiment of the multi-stage connector with strong and weak electrical interfaces and bidirectional fool-proof structure of the present invention includes a main housing 1, a plurality of strong wide connection terminals 2 and weak narrow connection terminals 3 installed in the main housing 1 and externally connected thereto. The weak current narrow wiring terminal of this embodiment is a wiring terminal 2.8 wide, and the strong current wide wiring terminal 2 is a wiring terminal 4.8 wide. The main casing body 1 is provided with a containing groove 4 for containing the weak current narrow wiring terminal 3, and the left inner wall and the right inner wall of the containing groove 4 are provided with separating ribs 4-1, so that a limiting door is formed at the tail end of the containing groove 4, the width of the limiting door is smaller than that of the strong current wide wiring terminal 2, and the width of the limiting door is larger than that of the weak current narrow wiring terminal 3. The spacer 4-1 of this embodiment is integrally formed with the main housing. The separation ribs 4-1 on the left inner wall and the right inner wall of the containing groove are symmetrically arranged, and the distance between a limiting door formed by the separation ribs and the tail end of the weak current narrow wiring terminal 3 is smaller than the length of a butt joint part of the plug connector inserted with the weak current narrow wiring terminal. The narrow wiring terminal of the weak current is blocked in the main shell by the limiting door, and the plug connector adaptive to the narrow wiring terminal can be put into the main shell, so that the wiring terminal is flexible in design, simple in structure and low in cost.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
