Abstract

The utility model discloses a more firm compound contact, including the contact piece, be provided with the screw thread space in the upper surface of contact piece, screw thread space female connection has the base member, the fixed contact that is provided with in upper end of base member, be provided with the screw space in the lower surface of contact piece, the screw space with it has the perforation to run through between the screw thread space, be provided with the screw thread chamber in the lower surface of base member, screw thread intracavity threaded connection has stop screw, through the setting to the screw thread direction or the pitch of screw thread chamber with the screw thread space for stop screw forms the locking effect to the base member, makes the base member unable rotation or removal, realizes stable fixed effect, and unless stop screw drops completely, even stop screw exists not hard up the condition, also can not influence the fixed of base member completely.

Description

More firm composite contact

Technical Field

The utility model relates to a compound contact field, concretely relates to more firm compound contact.

Background

The contact element is widely applied to electrical equipment products such as a switch, a relay, a temperature controller and the like. The existing composite contact is mostly riveted on a contact sheet with a hole through a riveting machine, but the riveted structure is not firm, and the contact is likely to loosen after being used for a period of time, so that the contact is poor in contact.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect among the above-mentioned prior art, the utility model provides a more firm compound contact for spacing screw forms the locking effect to the base member through the screw thread direction or the setting of pitch to screw thread chamber and screw thread space, makes the unable rotation of base member or removal, realizes stable fixed effect, unless spacing screw drops completely moreover, even spacing screw exists not hard up condition, also can not influence the fixed of base member completely.

Technical scheme

The utility model provides a more firm compound contact, includes the contact piece, be provided with the screw thread space in the upper surface of contact piece, screw thread space female connection has the base member, the fixed contact that is provided with in upper end of base member, be provided with the screw space in the lower surface of contact piece, the screw space with it has the perforation to run through between the screw thread space, be provided with the screw thread chamber in the lower surface of base member, screw thread intracavity threaded connection has stop screw.

Further, the head of the limiting screw is abutted to the top wall of the screw space.

Further, the limit screw only passes through the through hole.

Further, the thread cavity and the thread space have different pitches.

Further, the thread cavity and the thread space have different thread directions.

Advantageous effects

Compared with the prior art, the utility model, following beneficial effect has: through the setting to the screw thread direction or the pitch in screw thread chamber and screw thread space for spacing screw forms the locking effect to the base member, makes the unable rotation of base member or removal, realizes stable fixed effect, unless spacing screw drops completely moreover, even spacing screw exists not hard up the condition, also can not influence the fixed of base member completely.

Reference numerals

Contact piece 1, screw space 2, stop screw 3, perforation 4, screw space 5, screw cavity 6, contact 7, base member 8.

Detailed Description

For a better illustration of the invention, reference is made to the following description, taken in conjunction with the accompanying drawings and examples:

there is shown in fig. 1, the utility model discloses a more firm compound contact, including contact piece 1, be provided with screw space 5 in the upper surface of contact piece 1, screw space 5 female connection has base member 8, the fixed contact 7 that is provided with in upper end of base member 8, be provided with screw space 2 in the lower surface of contact piece 1, screw space 2 with it has perforation 4 to run through between the screw space 5, be provided with threaded cavity 6 in the lower surface of

base member

8, 6 female connection in threaded cavity has stop screw 3.

Further, the head of the limit screw 3 abuts against the top wall of the screw space 2.

Further, the limit screw 3 only passes through the through hole 4.

Further, the thread cavity 6 has a different pitch than the thread space 5.

Further, the thread cavity 6 has a different thread direction than the thread space 5.

Specifically, when the fixing is needed, the base body 8 is screwed into the threaded space 5 manually, and then the limit screw 3 penetrates through the through hole 4 and is screwed into the threaded cavity 6;

when the device is disassembled, the limit screw 3 is firstly screwed out, and then the base body 8 is screwed out.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions described in the foregoing embodiments may be modified, or some technical features may be equally replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
