Has the advantages that: the protruding piece part of the extension part is clamped into the clamping hole of the clamping part, so that the extension part and the clamping part are not deformed after long-term use, and the practicability is high.

Description

Improved terminal structure

technical field

The utility model relates to electromechanical products, in particular to an improved terminal structure.

Background technique

As shown in Figure 1, an extension sheet 12 is extended from one side of the housing 11 of the commonly used terminal 1, and the extension sheet 12 extends from the front edge and bends into the housing 11 to form a touch sheet 13. When placed in the housing 11 of the terminal 1, it will be in contact with the touch end 13 of the terminal 1 and conduct conduction. When the terminal 1 is used for a long time, the extension piece 12 of the housing 11 will easily be deformed and twisted. Needs to be improved.

Utility model content

The purpose of the utility model is to provide an improved terminal structure, which solves the problems that the extension piece of the housing is easily deformed and twisted when the common terminal is used for a long time.

The technical scheme of the utility model is: comprising a terminal body; an extension part, which is formed by extending from one side edge of the terminal body, and a protruding part is extended on the side edge of the extension part; The other side edge of the main body is extended, and an engaging hole is provided on one side edge, corresponding to the extension part; a contact part extends from the front edge of the extension part into the terminal body, and is supplied to the contact end of the counterpart Touch to achieve the purpose of conduction; the protruding part of the extension part is engaged in the engaging hole of the engaging part. With this design, the terminal body can be used for a long time without causing the extension part and the card The joint part causes deformation; wherein, the contact part is roughly perpendicular to the bottom surface of the terminal body; the terminal body is a long shell: the terminal body and the counterpart are used for insertion.

The utility model has the advantages that: the protruding part of the extension part is engaged in the engaging hole of the engaging part, and the extension part and the engaging part will not be deformed during long-term use, and the utility model has strong practicability.

Fig. 1 is a three-dimensional schematic diagram of a common terminal structure;

Fig. 2 is the three-dimensional schematic view of the utility model;

Fig. 3 is the schematic diagram that the utility model is assembled with wire;

4 and 5 are schematic diagrams of the utility model applied to a pair of handpieces.

Detailed ways:

As shown in accompanying drawings 2 and 3, the terminal structure 2 of the present invention includes a terminal body 3, an extension portion 31, an engaging portion 33 and a contact portion 35; wherein, the terminal body 3 constitutes the terminal structure 2 The main body can be an elongated shell;

The extension part 31 is formed by extending the side edge of the terminal body 3, and a tab part 32 is extended on the side edge of the extension part 31;

The engaging portion 33 extends from the other side of the terminal body 3 , and has an engaging hole 34 on one edge thereof, corresponding to the extending portion 31 ;

The contact portion 35 is extended from the front edge of the extension portion 31 into the terminal body 3 , and provides contact with the contact end of the counterpart to achieve conduction; the contact portion 35 is substantially perpendicular to the bottom surface of the terminal body 3 .

As shown in Figure 3, the fixing part 36 is located at the end of the terminal body 3, and a wire 4 can be inserted and connected. When the terminal structure 2 is bonding the wire 4, the wire 4 can be placed in the accommodation groove of the terminal body 3. 37, and then the fixing portion 36 of the terminal body 3 is pressed down to fix the wire 4.

As shown in accompanying drawings 4 and 5, the extended portion 31 of the terminal body 3 is extended with a tab portion 32, the engaging portion 33 of the terminal body 3 is provided with an engaging hole 34, and the tab portion of the extended portion 31 32 is engaged in the engaging hole 34 of the engaging portion 33. With this design, the extension portion 31 of the terminal body 3 and the engaging portion 33 of the terminal body 3 will not be damaged when the terminal body 3 is used for a long time. cause deformation;

When the user installs the opponent piece 5, he only needs to insert the contact end 51 of the opponent piece 5 into the terminal body 3, and make the contact end 51 of the opponent piece 5 touch the contact portion 35 of the terminal body 3. It can achieve the purpose of conduction.
