[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] like Figures 1 to 9 As shown, this embodiment provides a time relay, including: a housing 1, a light guide assembly, and a circuit board 5. The side wall of the housing 1 has multiple light guide holes 101. A baffle 3 is provided on the inner side wall of the housing 1 between two adjacent light guide holes 101. The light guide assembly includes multiple light guide heads 6, each corresponding to one of the multiple light guide holes 101, and the light guide heads 6 are inserted into the corresponding light guide holes 101. The circuit board 5 has multiple indicator lights 4, is disposed inside the housing 1 and abuts against the baffle 3, and the indicator lights 4 correspond one-to-one with the light guide heads 6. The baffle 3 is placed between two adjacent indicator lights 4. This arrangement, with the baffle 3 placed between two adjacent indicator lights 4, achieves optical isolation, preventing interference between the light from adjacent indicator lights 4 and avoiding misjudgment of the status. Especially in dim light or when the indicator lights are densely packed, the baffle 3 ensures that the display of each indicator light 4 is clearly distinguishable, helping operators quickly and accurately identify the current working stage of the time relay, effectively improving the indication effect and recognizability. Simultaneously, the baffle 3 can further position the circuit board 5, ensuring the stability and reliability of the structure. Specifically, indicator light 4 uses a surface-mount LED.

[0046] Optionally, multiple protruding ridges 7 are provided along the circumference of the light guide head 6, and the multiple protruding ridges 7 abut against the wall of the light guide hole 101. In this configuration, the multiple protruding ridges 7 achieve an interference fit between the light guide head 6 and the light guide hole 101, which enhances the fixing stability and prevents the light guide head 6 from loosening or falling off due to vibration, insertion or removal or temperature changes. At the same time, the light guide head 6 can be installed in place in one go, which is convenient for quick assembly and disassembly, and can meet the needs of one or more light guides.

[0047] Alternatively, please refer to Figures 2 to 5 As shown, to facilitate the positioning and installation of the light guide assembly, the light guide assembly also includes a light guide post 2, with multiple light guide heads 6 protruding from the light guide post 2. A positioning notch 201 for the baffle strip 3 to pass through is provided on the light guide post 2 between two adjacent light guide heads 6. It should be noted that the light guide assembly is made of transparent material.

[0048] Furthermore, in order to prevent the light guide post 2 from loosening or falling off in vibration environments and to improve its installation stability, the two ends of the light guide post 2 are respectively provided with a first post 8 and a second post 9, and both the first post 8 and the second post 9 are pressed onto the circuit board 5.

[0049] In this embodiment, please refer to Figures 6 to 8 As shown, in order to provide an interface for connecting to external circuits, the time relay also includes a wiring assembly, which includes an insulating base 10, a terminal block 11, and a connecting piece 12. The insulating base 10 is disposed inside the housing 1 and has a mounting groove. The terminal block 11 is disposed in the mounting groove. One end of the connecting piece 12 passes through the groove wall of the mounting groove and is connected to the terminal block 11. The other end of the connecting piece 12 is connected to the circuit board 5.

[0050] In this embodiment, the time relay can be provided with multiple insulating bases 10, and each insulating base 10 is provided with two terminals 11. Of course, in other embodiments, the number of terminals 11 on each insulating base 10 can be set according to actual needs, and no further restrictions are imposed here.

[0051] Optionally, in order to achieve effective isolation between two adjacent terminals 11 and prevent them from interfering with each other, the insulating base 10 is provided with multiple mounting slots, and an isolation slot 19 is provided between two adjacent mounting slots on the insulating base 10.

[0052] Optionally, the insulating base 10 is provided with clamping members 15, which are arranged one-to-one with the connecting pieces 12. Each clamping member 15 includes a first clamping piece 151 and a second clamping piece 152 spaced apart, with the other end of the connecting piece 12 positioned between the first clamping piece 151 and the second clamping piece 152. This arrangement allows the first clamping piece 151 and the second clamping piece 152 to effectively clamp the other end of the connecting piece 12, improving the installation stability of the connecting piece 12 and providing better isolation and anti-interference effects.

[0053] Optionally, the insulating base 10 is also provided with a guide base 16, which corresponds one-to-one with the connecting piece 12. The guide base 16 is provided with a guide groove, which is used to guide one end of the connecting piece 12 through the groove wall of the installation groove and connect to the terminal 11. With this configuration, the guide groove can ensure that one end of the connecting piece 12 moves or is installed along a preset path, avoiding offset or misalignment, preventing reverse insertion or tilting, effectively improving installation efficiency, and reducing the loosening or displacement of the connecting piece 12 caused by vibration during equipment operation. In addition, the groove wall of the guide groove also has the function of isolation and anti-interference.

[0054] Alternatively, please refer to Figure 6 and Figure 9 As shown, the guide seat 16 and the clamping member 15 are spaced apart along a first direction. The opening of the guide groove faces the clamping member 15. The connecting piece 12 includes a first connecting section 121, a bent section 122, and a second connecting section 123 connected in sequence. The first connecting section 121 passes through the groove walls of the guide groove and the mounting groove and connects to the terminal block 11. The second connecting section 123 is placed between the first clamping piece 151 and the second clamping piece 152, and both ends of the second connecting section 123 are provided with a first pin 13 and a second pin 14. The first pin 13 and / or the second pin 14 are soldered to the circuit board 5. It should be noted that the first direction is... Figure 6 The arrows indicate the direction. This configuration, employing a bent structure, achieves a compact design suitable for space-constrained applications, allowing for flexible layout and improved space utilization. Simultaneously, the bent design disperses stress on the connecting piece 12 under load, ensuring reliable contact and preventing stress concentration. It should be noted that the bending angle, length, and thickness of the connecting piece 12 can be adjusted according to specific circumstances to meet different performance requirements; no further limitations are made here.

[0055] Furthermore, both the edges of the first pin 13 and the second pin 14 are chamfered. With this configuration, when the first pin 13 and the second pin 14 are soldered onto the circuit board 5 in opposite directions, the chamfered structure can increase the contact area, reduce the risk of poor soldering, and further improve the quality and efficiency of soldering.

[0056] In this embodiment, a plurality of first storage slots 17 are provided on one side of the housing 1, and a plurality of second storage slots 18 are provided on the other side of the housing 1. Wiring assemblies are selectively installed in each first storage slot 17 and each second storage slot 18. It should be noted that when a wiring assembly is installed in a first storage slot 17 or a second storage slot 18, a slot corresponding to a wiring terminal 11 is formed on the inner top wall of the corresponding first storage slot 17 or second storage slot 18 to facilitate external circuit connection.

[0057] Furthermore, the first storage slots 17 and the second storage slots 18 are all arranged in a stepped manner.
