Reed self-correcting insertion structure and relay

Abstract

The present disclosure relates to the technical field of relays. Specifically disclosed are a reed self-correcting insertion structure and a relay. The reed self-correcting insertion structure comprises a base and a lead-out piece. An insertion slot is formed in the base, and the lead-out piece is fixedly inserted into the insertion slot. The insertion slot comprises a main limiting slot and a secondary limiting slot that are in communication with each other. The lead-out piece comprises a main body portion and a limiting portion located on one side of the main body portion, the main body portion and the limiting portion being respectively fixedly inserted into the main limiting slot and the secondary limiting slot. The width of the extending end of the limiting portion is greater than that of the starting end, and the shape of the limiting portion corresponds to that of the secondary limiting slot. That is, the lead-out piece undergoes punching and flattening by means of a wedge, forming the limiting portion, which, in cooperation with the structural features of the secondary limiting slot of the base, can pull and force the base to be vertical, enabling forced correction resetting of the lead-out piece. Thus, the accuracy of the insertion position of the lead-out piece on the base is ensured, thereby improving the verticality and stable reliability of the insertion.

Description

Reed self-calibrating insertion structure and relay

[0001] This disclosure claims priority to Chinese Patent Application No. 202421738479.4, filed on July 22, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of relay technology, specifically to a reed self-calibrating insertion structure and a relay. Background Technology

[0003] Existing lead-out pieces are flat, sheet-like or block-like structures of uniform thickness. The relay base has insertion slots corresponding to the shape of the lead-out pieces, which are then inserted into these slots. However, due to the high reference surface of the lead-out pieces (high insertion depth) and the influence of base warping and the demolding angle of the plastic parts, the measurement discrepancy between the insertion root and insertion opening of the lead-out pieces is amplified. This leads to an amplified tilting effect on the insertion of the lead-out pieces, resulting in larger errors and the inability to self-correct and reset, thus reducing the insertion position accuracy and affecting the perpendicularity and stability of the lead-out pieces inserted into the base. Summary of the Invention

[0004] The present disclosure aims to provide a reed self-aligning insertion structure to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution disclosed herein is as follows: a reed self-correcting insertion structure, comprising a base and a lead-out piece, wherein an insertion groove is formed on the base, and the lead-out piece is fixedly inserted into the insertion groove. The insertion groove includes a main limiting groove and a secondary limiting groove that are interconnected. The lead-out piece includes a main body and a limiting part extending outward from one side of the main body. The main body and the limiting part are respectively fixedly inserted into the main limiting groove and the secondary limiting groove. The width of the extended end of the limiting part is greater than the width of the extended head. The shapes of the limiting part and the secondary limiting groove correspond to each other, so that the lead-out piece can be forcibly corrected and reset within the insertion groove, thereby ensuring the insertion position accuracy of the lead-out piece on the base, and thus improving the verticality and stability of the insertion.

[0011] According to some embodiments of this disclosure, the limiting part and the secondary limiting groove are fixed by adhesive dispensing and plastic sealing.

[0012] According to some embodiments of this disclosure, the lead-out piece is a stationary spring lead-out piece or a moving spring lead-out piece.

[0013] According to some embodiments of this disclosure, a through hole is provided on the main limiting groove, and one end of the main body is bent to form a lead-out foot, which passes through the through hole and extends out of the base.

[0014] This disclosure also provides a relay including any of the above-described reed self-calibrating insertion structures.

[0015] This disclosure has the following beneficial effects:

[0016] This disclosure includes a base and a lead-out piece. The base has an insertion groove, and the lead-out piece is fixedly inserted into the insertion groove. The insertion groove includes a main limiting groove and a secondary limiting groove that are interconnected.

[0028] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] Referring to Figures 1-8, as an embodiment of this disclosure, a reed self-correcting insertion structure is provided, including 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. An insertion groove is formed on the base 1, and the lead-out piece 2 is fixedly inserted into the insertion groove. The insertion groove includes a main limiting groove 11 and a secondary limiting groove 12 that are interconnected. 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 body portion 21. Within the limiting groove 11 and the secondary limiting groove 12, the width of the extended end of the limiting part 22 is greater than the width of the extended head. The shapes of the limiting part 22 and the secondary limiting groove 12 correspond to each other. The limiting part 22 of the lead-out piece 2 disclosed herein, in conjunction with the structural features of the secondary limiting groove 12 of the base 1, can pull the plastic base 1 to be forced vertical, so that the lead-out piece 2 can be forcibly corrected and reset, thereby ensuring the insertion position accuracy of the lead-out piece 2 on the base 1, and thus improving the verticality and stability of the insertion.

[0030] In this embodiment, the main body 21 is a long rectangular block. The insertion direction of the main body 21 is defined as the z-axis direction, the thickness direction as the x-axis direction, and the direction perpendicular to the z and x axes as the y-axis direction. The limiting part 22 is formed by being located on one side of the main body 21 and extending along the x-axis direction. That is, the extension direction of the limiting part 22 is perpendicular to the thickness surface of the main body 21, which further improves the perpendicularity and stability of the lead-out piece 2 inserted on the base 1.

[0031] Referring to Figures 1 and 4, in this embodiment, one end of the main limiting groove 11 along the y-axis is a clamping groove 14, and one end of the main body 21 along the y-axis is a fixed end 211. The size of the clamping groove 14 corresponds to the size of the fixed end 211, so that the fixed end 211 can be firmly clamped in the clamping groove 14. Through the auxiliary clamping and limiting of the clamping groove 14, the insertion position accuracy of the lead-out piece 2 is improved, and the perpendicularity and positioning reliability of the insertion are further improved.

[0032] Referring to Figure 4, in this embodiment, the limiting part 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. Moreover, the length of the limiting part 22 is greater than the depth of the secondary limiting groove 12, and the length of the main part 21 is greater than the main limiting groove 11, so as to always satisfy the limiting effect of the lead-out piece 2 on the base 1.

[0033] In this embodiment, the lead-out piece 2 is a stationary spring lead-out piece or a moving spring lead-out piece.

[0034] Referring to Figure 6, in this embodiment, the limiting part 22 has a T-shaped cross-section. The limiting part 22 includes a rectangular segment 222 and a trapezoidal segment 221 located at one end of the main body 21 away from the rectangular segment 222. The width of the trapezoidal segment 221 gradually increases in the direction away from the rectangular segment 222. This arrangement makes the assembly accuracy of the limiting part 22 within the secondary limiting groove 12 higher and the anti-loosening and tilting effect better. Of course, in other cases, the cross-section of the limiting part 22 can also be L-shaped.

[0035] Referring to Figure 5, in this embodiment, the bottom end of the limiting part 22 is provided with a guide slope 223, which facilitates the precise insertion of the limiting part 22 into the secondary limiting groove 12. The limiting part 22 and the secondary limiting groove 12 are fixed by glue application and plastic sealing, thereby increasing the bonding force and further ensuring the reliability of the insertion of the lead-out piece 2 on the base 1.

[0036] Referring to Figures 2, 3 and 4, in this embodiment, a through hole 13 is provided on the main limiting groove 11, and one end of the main body 21 is bent to form an extension foot 23, which extends out of the base 1 through the through hole 13.

[0037] This disclosure also provides a relay including the reed self-correcting insertion structure described in the above embodiments, which enables the lead-out piece to be forcibly corrected and reset during insertion, thereby ensuring the insertion position accuracy of the lead-out piece on the base, and thus improving the verticality and stability of the insertion.

[0038] Although this disclosure has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to this disclosure without departing from the spirit and scope of this disclosure as defined by the appended claims fall within the protection scope of this disclosure.
