Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically, to a connector with an anti-misoperation locking structure. Background Technology

[0002] To prevent the male and female terminals of the connector from loosening after connection, existing technology typically involves hinged a snap-on plate to the female terminal, with an added torsion spring causing the snap-on plate to tilt towards the end connected to the male terminal. A retaining ring is located on the male end of the snap-on plate. Correspondingly, a locking block is located on the male terminal. After connection, the torsion spring keeps the retaining ring locked to the locking block, preventing the male and female terminals from separating. However, existing technology lacks a design to prevent the snap-on plate from unlocking. In actual use, the snap-on plate can be easily lifted by contact or pressure, causing the retaining ring to detach from the locking block, resulting in locking failure. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a connector with an anti-misinterlocking structure.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A connector with an anti-misoperation locking structure includes a locking block on the male end, a snap plate hinged to the female end and capable of being locked in place by the locking block, and an elastic element that tilts the front end of the snap plate downwards. The rear end of the snap plate is fitted with an unlocking block that can move back and forth. The unlocking block is provided with a limiting shaft, and the female end is provided with a limiting groove. The limiting shaft is engaged in the limiting groove and can move along the limiting groove. The limiting groove is provided with a blocking point that can prevent the limiting shaft from moving along the limiting groove. When the front end of the snap plate tilts downwards, the limiting shaft moves upwards along the limiting groove until it enters the blocking point.

[0006] Furthermore, the top surface of the female end is provided with limiting plates on both sides, the limiting groove has two grooves and is symmetrically arranged on the limiting plates on both sides, and the limiting shaft has two shafts and is respectively fitted into the limiting grooves on both sides.

[0007] Furthermore, the blocking point is located at the top of the limiting groove, the limiting groove includes an inclined section communicating with the blocking point, and the blocking point is a blocking surface provided on the downward inclined surface that points vertically downward from the top of the inclined section, which can accommodate the limiting shaft.

[0008] Furthermore, the rear end of the blocking surface is inclined toward the rear of the mother end.

[0009] Furthermore, the limiting groove also includes a vertical section, which is connected to the lower part of the inclined section.

[0010] Furthermore, the top of the inclined segment slopes backward toward the mother end.

[0011] Furthermore, a spring is provided between the buckle plate and the unlocking block to keep the limiting shaft abutting against the blocking point.

[0012] Furthermore, the top surface of the unlocking block is also provided with several anti-slip textures.

[0013] In summary, the beneficial effects of this utility model are as follows: This utility model features an unlocking block on the buckle plate. Through a limiting shaft on the unlocking block engaging with a limiting groove on the female end, after the male and female ends are connected, the front end of the buckle plate rotates downwards to tilt and engage the locking block. At this time, the limiting shaft moves upwards along the limiting groove to enter the blocking position, preventing the limiting shaft from moving along the limiting groove. This restricts the buckle plate from being squeezed and thus prevents it from unlocking from the locking block, preventing accidental locking. When unlocking is required, manually push the unlocking block to move the limiting shaft away from the blocking position. The limiting shaft can then move along the limiting groove. Pressing the unlocking block again will push the buckle plate to rotate and unlock. Attached Figure Description

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Refer to 1 to Figure 3 A connector with an anti-misoperation locking structure includes a locking block 11 on the male end 1, a latching plate 3 hinged to the female end 2 and capable of being latched by the locking block 11, and an elastic element that tilts the front end of the latching plate 3 downwards. An unlocking block 4 is fitted onto the rear end of the latching plate 3, which is movable back and forth. The unlocking block 4 has a limiting shaft 41, and the female end 2 has a limiting groove 22. The limiting shaft 41 engages within the limiting groove 22 and can move along the groove. The limiting groove 22 has a blocking point that prevents the limiting shaft 41 from moving along it. When the front end of the latching plate 3 tilts downwards, the limiting shaft 41 moves upwards along the limiting groove 22 until it enters the blocking point. The elastic element is preferably a torsion spring, which is not shown in the accompanying drawings.

[0024] The movement trajectory of the limiting shaft 41 is limited by the limiting groove 22. After the buckle plate 3 and the locking block 11 are engaged, the limiting shaft 41 enters the blocking area, preventing the limiting shaft 41 from moving along the limiting groove 22. This restricts the buckle plate 3 from being squeezed and thus prevents the buckle plate 3 from unlocking from the locking block 11, preventing accidental locking. When unlocking, manually push the unlocking block 4 to move the limiting shaft 41 away from the blocking area. At this time, the limiting shaft 41 can move along the limiting groove 22. Pressing the unlocking block 4 will push the buckle plate 3 to rotate and unlock. To prevent greater friction between the finger and the unlocking block 4 when pressing, several anti-slip textures 42 are also provided on the top surface of the unlocking block 4.

[0025] In one embodiment, such as Figure 1As shown, the top surface of the female end 2 is provided with limiting plates 21 on both sides. Two limiting grooves 22 are symmetrically arranged on the limiting plates 21 on both sides. Two limiting shafts 41 are provided, each fitting into one of the limiting grooves 22 on one side. By providing two limiting plates 21 on the female end 2, and correspondingly providing two limiting grooves 22 and two limiting shafts 41, the limiting shafts 41 can be smoothly and steadily limited using the limiting grooves 22.

[0026] In one embodiment, the blocking point is located at the top of the limiting groove 22. The limiting groove 22 includes an inclined section 221 communicating with the blocking point. The blocking point is a blocking surface 222 located on the vertically downward inclined surface at the top of the inclined section 221, which can accommodate the limiting shaft 41. Due to the action of the elastic element, the rear end of the buckle 3 will remain in an upward tilted state. Under the restriction of the inclined section 221 of the limiting groove 22, the limiting shaft 41 will enter the blocking point along the inclined section 221. At this time, if the unlocking member is pressed, the limiting shaft 41 will rotate downward about the hinge point between the buckle 3 and the female end 2, and will be blocked by the vertically downward blocking surface 222 at the top of the inclined section 221, preventing further rotation and preventing the buckle 3 from disengaging from the locking block 11.

[0027] like Figure 2 As shown, in one embodiment, the rear end of the blocking surface 222 is inclined toward the rear of the female end 2. When the unlocking member is pressed so that the limiting shaft 41 abuts against the blocking surface 222, the rearward inclination of the blocking surface 222 will cause the unlocking member to tend to move toward the rear end, thus better preventing the limiting shaft 41 from disengaging from the blocking point.

[0028] like Figure 2 As shown, in one embodiment, the limiting groove 22 further includes a vertical section 223, which communicates with the lower part of the inclined section 221. The vertical section 223 allows the limiting shaft 41 to move downwards more quickly after disengaging from the obstruction and entering the vertical section 223 via the inclined section 221. Pressing the unlocking member reduces the resistance to unlocking the buckle 3 and the locking block 11, making unlocking smoother.

[0029] like Figure 2 As shown, in one embodiment, the top of the inclined segment 221 is inclined towards the rear of the female end 2. During unlocking, the thumb presses the unlocking member forward and downward, causing the limiting shaft 41 to disengage from the obstruction before pressing to unlock.

[0030] In one embodiment, such as Figure 3 As shown, a spring 5 is also provided between the buckle plate 3 and the unlocking block 4. By providing the spring 5, the limiting shaft 41 can be better kept against the blocking point, further preventing the limiting shaft 41 from disengaging from the blocking point.

[0031] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
