Description

Technical Field

[0001] The utility model relates to the technical field of relays, and particularly relates to a reed self-correcting insertion structure and a relay. Background Art

[0002] The existing lead-out piece is a flat sheet or block structure with a uniform thickness. A socket groove corresponding to the shape of the lead-out piece is provided on the base of the relay. The lead-out piece is inserted into the socket groove. However, due to the relatively high reference surface (high insertion depth) of the lead-out piece and the influence of the warping deformation of the base and the plastic part forming demolding angle, there is a problem of amplified measurement scatter between the insertion root and the insertion mouth of the lead-out piece, resulting in an amplified effect of the insertion tilt of the lead-out piece, which will cause the error to become larger, and self-correction and reset cannot be performed, reducing the insertion position accuracy, thereby affecting the perpendicularity and stable reliability of the insertion of the lead-out piece on the base. Content of the Utility Model

[0003] The utility model aims to provide a reed self-correcting insertion structure to solve the above-mentioned existing technical problems.

[0004] To achieve the above object, the technical solution of the utility model is: a reed self-correcting insertion structure, including a base and a lead-out piece. A socket groove is formed on the base. The lead-out piece is fixedly inserted into the socket groove. The socket groove includes a main limiting groove and a secondary limiting groove that communicate with each other. The lead-out piece includes a main body part and a limiting part located on one side of the main body part. The main body part and the limiting part are respectively fixedly inserted into the main limiting groove and the secondary limiting groove. The width of the extending end of the limiting part is greater than the width of the extending starting end. The shape of the limiting part corresponds to the shape of the secondary limiting groove, so that the lead-out piece can be forced to correct and reset in the socket groove, thereby ensuring the insertion position accuracy of the lead-out piece on the base, and further improving the perpendicularity and stable reliability of the insertion.

[0028] Refer to Figure 1-8As shown in the figure, as an embodiment of the present utility model, a reed self-correcting insertion structure is provided, which includes a base 1 and a lead-out piece 2. The base 1 is a plastic component, and the lead-out piece 2 is a metal component. A plug-in groove is formed on the base 1, and the lead-out piece 2 is fixedly inserted into the plug-in groove. The plug-in groove includes a main limiting groove 11 and a secondary limiting groove 12 that communicate with each other. The lead-out piece 2 includes a main body portion 21 and a limiting portion 22 located on one side of the main body portion 21. The main body portion 21 and the limiting portion 22 are respectively fixedly inserted into the main limiting groove 11 and the secondary limiting groove 12. The width of the extending end of the limiting portion 22 is greater than the width of the extending starting end. The shape of the limiting portion 22 corresponds to that of the secondary limiting groove 12. The lead-out piece 2 of the present utility model is blanked and flattened by means of a cambered block to form the limiting portion 22. By cooperating with the structural features of the secondary limiting groove 12 of the base 1, the plastic base 1 can be forced to be perpendicular, so that the lead-out piece 2 can be forced to correct and reset, thereby ensuring the insertion position accuracy of the lead-out piece 2 on the base 1, and further improving the verticality and stability reliability of the insertion.

[0029] In this embodiment, the main body portion 21 is a long rectangular block. Define the insertion direction of the main body portion 21 as the z-axis direction, the thickness direction as the x-axis direction, and the direction perpendicular to both the z-axis and the x-axis as the y-axis direction. Then the limiting portion 22 is formed by extending along the x-axis direction on one side of the main body portion 21, that is, the extending direction of the limiting portion 22 is perpendicular to the thickness plane of the main body portion 21, further improving the verticality and stability reliability of the insertion of the lead-out piece 2 on the base 1.

[0030] In this embodiment, one end of the main limiting groove 11 corresponding to the y-axis direction is a clamping notch 14, and one end of the limiting portion 22 corresponding to the y-axis direction is a fixed end 221. The size of the clamping notch 14 corresponds to the size of the fixed end 221, so that the fixed end 221 can be firmly clamped in the clamping notch 14. Through the auxiliary clamping and limiting of the clamping notch 14, the insertion position accuracy of the lead-out piece 2 is improved, and the verticality and positioning reliability of the insertion are further improved.

[0031] In this embodiment, the limiting portion 22 has a long strip structure, and its length direction is parallel to the z-axis direction, that is, the same as the insertion direction, to ensure the insertion depth and stability. And the length of the limiting portion 22 is greater than the depth of the secondary limiting groove 12, and the length of the main body portion 21 is greater than that of the main limiting groove 11, so as to always meet the limiting effect of the lead-out piece 2 on the base 1.

[0032] In this embodiment, the lead-out piece 2 is a static reed lead-out piece or a dynamic reed lead-out piece.

[0033] In this embodiment, the cross-section of the limiting portion 22 is T-shaped. The limiting portion 22 includes a rectangular section 222 and a trapezoidal section 221 located at one end of the main body portion 21 away from the rectangular section 222. The width of the trapezoidal section 221 gradually increases in the direction away from the rectangular section 222. This setting makes the assembly accuracy of the limiting portion 22 in the secondary limiting groove 12 higher and the anti-loosening and anti-tilting effect better. Of course, in other cases, the cross-section of the limiting portion 22 can also be L-shaped.

[0034] In this embodiment, a guiding inclined surface 223 is provided at the bottom end of the limiting portion 22, which facilitates the accurate guiding and insertion of the limiting portion 22 into the secondary limiting groove 12. The limiting portion 22 and the secondary limiting groove 12 are fixed by dispensing and plastic sealing, thereby increasing the bonding force and further ensuring the insertion reliability of the lead piece 2 on the base 1.

[0035] In this embodiment, a through hole 13 is formed in the main limiting groove 11. One end of the main body portion 21 is bent to form a lead foot 23, and the lead foot 23 passes through the through hole 13 and extends out of the base 1.

[0036] The present utility model also provides a relay, including the reed self-correcting insertion structure described in the above embodiment, so that the lead piece can be forced to correct and reset during insertion, thereby ensuring the insertion position accuracy of the lead piece on the base, and further improving the verticality and stability reliability of the insertion.

[0037] Although the present utility model is specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present utility model in form and detail without departing from the spirit and scope of the present utility model defined by the appended claims all fall within the protection scope of the present utility model.
