[0025] Electronic devices often utilize modular designs, with connectors connecting different modules to enable the coordinated operation of the entire system. They connect various electrical and electronic components, such as power, signals, and data, and are an indispensable component of the entire circuit. Connectors are used in a wide range of applications, including computers, mobile phones, home appliances, automobiles, and medical equipment. Modular connectors allow various electronic modules to be assembled together to form a more complete system, while also facilitating maintenance and upgrades. Existing electronic devices primarily use braided metal connectors, plug-in connectors, and nuts to connect modules. These methods typically utilize board-to-board or board-to-cable connectors, which lack locking features and are therefore pluggable. These methods can lead to certain limitations in product connection reliability. To ensure a more secure connection, connectors often require additional components such as foam and metal shells for additional locking. This significantly increases equipment cost and can easily lead to mis-locking.
[0026] refer to Figure 1 To solve the above problems, the embodiment of the present application provides a sliding locking structure 10, including a base 20, a back cover 30 and a slide plate 40. First guide members 21 are provided on opposite sides of the base 20, the back cover 30 is fixed to the base 20, and a first snap structure 31 is provided on the side of the back cover 30 away from the base 20. Second guide members 41 that slide and engage with the first guide members 21 are provided on opposite sides of the slide plate 40. The slide plate 40 is located on the side of the back cover 30 away from the base 20. A second snap structure 42 that cooperates with the first snap structure 31 is provided at the bottom of the slide plate 40. The slide plate 40 can slide relative to the back cover 30 to switch between a first position P1 and a second position P2. The first snap structure 31 and the second snap structure 42 can snap with each other at the first position P1 and the second position P2.
[0027] In the sliding lock structure 10, the sliding lock structure 10 includes a base 20, a back cover 30, and a slide 40. First guide members 21 are provided on opposite sides of the base 20. The first guide members 21 can be symmetrically arranged on both sides of the base 20. Second guide members 41 are provided on opposite sides of the slide 40. The first guide members 21 and the second guide members 41 can be slidably engaged with each other. The first guide members 21 and the second guide members 41 provide guidance for the slide 40 relative to the base 20 and also enable the slide 40 to move along a set trajectory. The engagement between the first guide members 21 and the second guide members 41 prevents the slide 40 from separating from the base 20 during movement. In some embodiments, the second guide members 41 can have a certain movement distance, allowing the first guide member 21 to move a certain distance within the second guide members 41. The back cover 30 is fixed to the base 20. When the slide 40 moves relative to the base 20, the back cover 30 and the base 20 are in a relatively stationary state, that is, the slide 40 can move relative to the back cover 30 and the base 20. The back cover 30 is provided with a first snap-fit structure 31, and the slide 40 is provided with a second snap-fit structure 42. Specifically, the first snap-fit structure 31 is provided on the side of the back cover 30 facing away from the base 20, and the second snap-fit structure 42 is provided on the side of the slide 40 facing the back cover 30. The first snap-fit structure 31 and the second snap-fit structure 42 cooperate with each other. In some embodiments, the first snap-fit structure 31 and the second snap-fit structure 42 can abut against each other. For example, the first snap-fit structure 31 is a convex structure, and the second snap-fit structure 42 is a concave structure, and the convex structure can be embedded in the concave structure and the edges of the two abut against each other. Then, when the first snap-fit structure 31 and the second snap-fit structure 42 abut against each other, the position between the slide 40 and the back cover 30 can be relatively fixed. In some embodiments, the second snap-fit structure 42 can be configured as a spring 421. Specifically, when the spring 421 is pressed toward one side of the slide 40, the spring 421 is in a compressed state. When the force applied to the spring 421 is released, the second snap-fit structure 42 can be snapped into the first snap-fit structure 31 with which it cooperates. The slide 40 of the sliding lock structure 10 is movable. Specifically, the slide 40 can slide relative to the back cover 30 to switch between a first position P1 and a second position P2. In some embodiments, the first position P1 is configured as a locked state, and the second position P2 is configured as an unlocked state. The first snap-fit structure 31 and the second snap-fit structure 42 can interlock with each other at the first position P1 and the second position P2. In the above structure, due to the interlocking relationship, the sliding lock structure 10 can be tightly connected and has a simple structure. The above structure provides a simple sliding state switching structure, and the structure can also provide an effective anti-misoperation locking function.
[0028] See Figure 1 、 Figure 2 and Figure 3In some embodiments, the first latch structure 31 includes a first locking groove 311 and a second locking groove 312 spaced apart along the sliding direction of the slide plate 40. The first locking groove 311 and the second locking groove 312 can be used to cooperate with the second latch structure 42 to achieve the locking of the sliding latch structure 10 in the first position P1 and the second position P2. Specifically, the first position P1 is set to the locked state, and the second position P2 is set to the unlocked state. The locking groove on the side closer to the first position P1 is the first locking groove 311, and the locking groove on the side closer to the second position P2 is the second locking groove 312. The second latch structure 42 includes a spring 421. The spring 421 is in a naturally popped-up state and protrudes from the bottom of the slide plate 40 toward the side of the rear cover 30. During operation, the slide plate 40 is slid. When the slide plate 40 slides to the first position P1, the spring piece 421 is engaged with the first locking groove 311. When the slide plate 40 slides to the second position P2, the spring piece 421 is engaged with the second locking groove 312. Before the slide plate 40 moves to the first position P1 or the second position P2, the spring piece 421 is in a compressed state. That is, the back cover 30 exerts a force on the spring piece 421 toward the slide plate 40. The spring piece 421 is in a compressed state and does not protrude, thereby not affecting the normal sliding of the slide plate 40. When the slide plate 40 slides to the first position P1 or the second position P2, the first locking groove 311 or the second locking groove 312 can provide a certain space for the spring piece 421, thereby reducing the pressure of the slide plate 40 on the spring piece 421 during the sliding process or directly reducing the above pressure to zero. At this time, the spring piece 421 bounces up and then snaps into the first locking groove 311 or the second locking groove 312 to achieve the snap connection between the first snap structure 31 and the second snap structure 42.
[0029] See Figure 2The first guide member 21 includes a first protrusion 44211, and the second guide member 41 includes a slide groove 411. The first protrusion 44211 can move in the slide groove 411. The extension direction of the slide groove 411 is parallel to the sliding direction of the slide plate 40. When the slide plate 40 slides relative to the base 20 and the back cover 30, the first protrusion 44211 moves in the slide groove 411 in the same direction as the movement of the slide plate 40. The structure of setting the first protrusion 44211 and the slide groove 411 can make the movement of the slide plate 40 follow a predetermined trajectory, thereby preventing the slide plate 40 from falling off from the base 20 when moving. In one embodiment, the first protrusion 44211 is slidably disposed in the slide groove 411. Specifically, the first protrusion 44211 includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the second connecting portion. The first connecting portion is slidably disposed in the slide groove 411. The second connecting portion is away from the base 20 in a first direction, and the first direction is perpendicular to the moving direction of the slide 40. At the same time, the size of the second connecting portion is larger than the first connecting portion. At this time, the second connecting portion can ensure that the first protrusion 44211 will not fall off in the first direction, which can further ensure the stability of the slide 40 during movement. Figure 2 and Figure 3 In some embodiments, a slide rail 35 is provided on one side of the back cover 30 facing the slide plate 40. The direction of the slide rail 35 is parallel to the sliding direction of the slide plate 40. A protrusion 44 is provided at the bottom of the slide plate 40. The protrusion 44 is slidably disposed in the slide rail 35 to further ensure the sliding stability of the slide plate 40 so that the slide plate 40 will not separate from the back cover 30 when sliding.
[0030] In some embodiments, opposite sides of the slide 40 extend toward the base 20 to form first side wings 43, with a slide groove 411 defined in the first side wings 43. The photo album on the back cover 30 forms a second side wing 32. The first side wing 43 and the second side wing 32 are positioned opposite each other in the sliding direction of the slide 40. In some embodiments, the outer sides of the first side wing 43 and the outer sides of the second side wing 32 are aligned in the same straight line in the direction of movement of the slide 40. This allows for a compact structure of the sliding lock structure 10, reduces the volume of the sliding lock structure 10, and effectively reduces the cost of the sliding lock structure 10. In some embodiments, the back cover 30 is fixedly connected to the base 20 via the second side wing 32, thereby maintaining a relative fixed position between the back cover 30 and the base 20. For example, the base 20 may be provided with a second protrusion corresponding to the position of the second side wing 32, and the second side wing 32 may be provided with a first slot. The second protrusion may be embedded in the first slot to maintain a relative fixed position between the base 20 and the back cover 30. In some embodiments, the first side wing 43 and the second side wing 32 abut against the side wings of the base 20 , so that the slide 40 , the rear cover 30 and the base 20 form a compact structure.
[0031] See Figure 1 、 Figure 2 and Figure 3 The size of the slide 40 in the sliding direction is smaller than that of the back cover 30. That is, when the slide 40 is located on the upper side of the back cover 30, a portion of the back cover 30 will be exposed and not blocked by the slide 40. During the movement of the slide 40, the operator can easily observe the position of the slide 40, which facilitates the determination of the position of the slide 40 on the back cover 30. It also facilitates the determination of whether the sliding lock structure 10 is in a locked or unlocked state. Specifically, in some embodiments, a first mark 33 and a second mark 34 are provided on a side of the back cover 30 facing the slide 40. The first mark 33 and the second mark 34 are spaced apart along the sliding direction. When the slide 40 is in the first position P1, the first mark 33 is blocked and the second mark 34 is exposed. When the slide 40 is in the second position P2, the second mark 34 is blocked and the first mark 33 is exposed. For example, the first mark 33 is an unlock mark, and the second mark 34 is a lock mark. When the operator slides the slide 40, when the slide 40 is in the first position P1, the first mark 33 on the back cover 30 is blocked by the slide 40, revealing the second mark 34, i.e., the lock mark. At this time, the sliding lock structure 10 is in the locked state, and the second latch structure 42 is engaged with the first locking groove 311. When the slide 40 is in the second position P2, the second mark 34 on the back cover 30 is blocked by the slide 40, revealing the first mark 33, i.e., the unlock mark. At this time, the sliding lock structure 10 is in the unlocked state, and the second latch structure 42 is engaged with the second locking groove 312. During the sliding process of the slide 40, the first protrusion 44211 moves in the same direction as the movement of the slide 40 within the slide groove 411, thereby realizing the process of unlocking and locking the sliding lock structure 10 by sliding the slide 40. During the sliding process of the slide 40, the positions of the back cover 30 and the base 20 are relatively fixed. In some embodiments, the first snap-fit structure 31 is located between the first identifier 33 and the second identifier 34, with the first identifier 33 close to one side of the first locking groove 311 and the second identifier 34 close to one side of the second locking groove 312, ensuring that when the first snap-fit structure 31 and the second snap-fit structure 42 are engaged, the first identifier 33 and the second identifier 34 can be revealed.
[0032] The relay of the embodiment of the second aspect of the present invention includes a relay terminal 50 and a sliding lock structure 10 of the embodiment of the second aspect of the present invention. The relay terminal 50 mostly refers to a wiring terminal, also called a wiring terminal, which is a component used to connect the relay to the external circuit. They play an important role in the operation of the relay. There are many types of relay terminals 50. According to different application scenarios and needs, a suitable relay terminal 50 can be selected to improve the reliability and service life of the relay. The relay terminal 50 can play the role of connecting the circuit in the circuit. In some embodiments, the base 20 is provided with a mounting groove on the side facing the back cover 30, and the relay terminal 50 can be placed in the mounting groove. The structure is simple. The above structure provides a relay with a simple sliding state switching structure, and the structure can also provide an effective anti-misinterpretation lock function. Since this embodiment adopts all the technical features of the sliding lock structure 10 of the embodiment of the first aspect, this embodiment has all the beneficial effects brought by the embodiment of the first aspect, which will not be repeated here.
[0033] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0034] The above embodiments merely illustrate several implementations of the present invention.
