Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, and specifically discloses a surge protector plug-in structure. Background Technology

[0002] A surge protector is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike is suddenly generated in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. The protector includes a functional module (lightning arrester) and a base for inserting and removing the functional module. The functional module is equipped with pins, which are connected to the circuit by engaging with the sockets on the base, while simultaneously fixing the functional module to the base.

[0003] For example, patent CN217769483U, published on 2022-11-08, discloses a surge protector, including a base, a first terminal and a second terminal respectively disposed at both ends of the base, and a surge protection module disposed on the base. The surge protection module includes a housing disposed on the base, a support seat disposed within the housing, a varistor disposed on the support seat, an input plug disposed on one end of the varistor and plugged into the first terminal, and an output plug disposed on the support seat and plugged into the second terminal. The output plug has a bent thermal trip piece, which is soldered to the other end of the varistor. A trip indicator that cooperates with the bent thermal trip piece is rotatably disposed on the support seat. A spring is disposed between the trip indicator and the support seat. An indicator hole that cooperates with the trip indicator is disposed on the housing, and a communication module that cooperates with the trip indicator is disposed inside the base.

[0004] The shortcomings of existing surge protectors, including the aforementioned patents, are that the functional modules are simply connected to the base by pins. During use, the connection is easily loosened due to instability, which can cause the functional modules to fail and thus lose their protective function. Utility Model Content

[0005] The purpose of this invention is to provide a protector plug-in structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protector plug-in structure includes a functional module and a base. The functional module includes a housing and pins mounted on the housing. The base has corresponding holes for the pins. A locking block is also movably mounted on the housing. When the pins are fully inserted into the holes, the locking block is driven to pop out and lock the housing onto the base.

[0008] In the above-mentioned plug-in structure, the locking block is rotatably mounted on the side of the housing, the base is provided with a locking groove that matches the locking block, and the housing is provided with an elastic element that drives the locking block to rotate outward.

[0009] In the above-mentioned plug-in structure, the lower part of the locking block is rotatably connected to the side of the housing via a rotating shaft. The elastic element is a torsion spring fitted on the rotating shaft. When the torsion spring is in its natural state, the locking block protrudes from the side of the housing.

[0010] The above-mentioned plug-in structure has two sets of locking blocks, which are symmetrically arranged on both sides of the housing.

[0011] The aforementioned plug-in structure also has a guide groove on the base. The width of the guide groove is equal to the width of the locking block, and the guide groove and the locking groove are directly opposite each other. When the locking block is in the retracted state, it protrudes from the side of the housing.

[0012] The aforementioned plug-in structure also includes an adjustment component on the housing that can drive the locking block to change from the second state to the first state.

[0013] The above-mentioned plug-in structure includes a locking block comprising a side plate and an arc-shaped plate fixed to the side plate. The adjusting component includes an adjusting rod that passes through the arc-shaped plate. The adjusting rod is slidably installed on both sides of the housing and has an inclined surface. When the adjusting rod is driven to move upward toward the housing, the inclined surface of the adjusting rod contacts the arc-shaped plate and pushes the arc-shaped plate into the housing.

[0014] The above-mentioned plug-in structure includes an adjusting rod comprising a first vertical section, an inclined section, and a second vertical section connected in sequence, wherein the width of the first vertical section is smaller than the width of the second vertical section.

[0015] In the above-mentioned plug-in structure, a protrusion is fixed to the upper end of the adjusting rod, and the protrusion protrudes from the side of the housing.

[0016] In the above-mentioned plug-in structure, a spring is fixedly connected inside the housing. The upper end of the spring is fixedly connected to the second vertical section. When the spring is in its natural state, the first vertical section is in the adjustment hole.

[0017] In the above technical solution, the protector plug-in structure provided by this utility model, by rotating and installing a fan-shaped locking block on the side of the housing, and cooperating with the guide groove and locking groove opened on the base, can guide the movement of the housing during the installation process through the cooperation of the locking block and the guide groove. When the housing is installed, the locking block is driven by the torsion spring to rotate and cooperate with the locking groove to lock the housing on the base, preventing the connection between the housing and the base from loosening due to vibration.

[0029] like Figures 1-6 As shown in the figure, the present invention provides a protector plug-in structure, including a functional module and a base 1. The functional module includes a housing 2 and a pin 21 installed on the housing 2. The base 1 has a socket 11 corresponding to the pin 21. A locking block 3 is also movably installed on the housing 2. When the pin 21 is fully inserted into the socket 11, the locking block 3 is driven to pop out and lock the housing 2 on the base 1.

[0030] Specifically, the base 1 is concave, and the functional module is adapted to the concave part of the base 1. The functional module includes a housing 2, and a pin 21 is installed on the lower surface of the housing 2. The pin 21 has a U-shaped structure, and the bottom of the concave part of the base 1 has a socket 11 that matches the pin 21. Figures 2 to 5 As shown, the pins 21 are provided in two sets and symmetrically arranged on the lower surface of the housing 2; a locking block 3 is also movably installed on the housing 2. The locking block 3 has a first state and a second state. When it is in the first state, the locking block 3 is retracted inside the side of the housing 2, while when it is in the second state, the locking block 3 extends outward from the side of the housing 2.

[0031] Optionally, such as Figure 4 As shown, the locking block 3 is rotatably mounted on the side of the housing 2, and the base 1 is provided with a locking groove 12 that matches the locking block 3. The housing 2 is provided with an elastic element that drives the locking block 3 to rotate outward.

[0032] Specifically, the locking block 3 is rotatably mounted on the side of the housing 2. Optionally, the locking block 3 is fan-shaped, and the center point of the fan-shaped locking block 3 is located at... Figure 4The lower end in the view is rotatably connected to the housing 2, and the housing 2 is provided with an elastic element that drives the locking block 3 to rotate outward. The base 1 is provided with a locking groove 12 that matches the locking block 3. The locking groove 12 is fan-shaped. During the process of the housing 2 moving inward to the base 1, the locking block 3 is blocked by the side wall of the recessed part on the base 1 and remains in the first state. When the housing 2 and the base 1 are fully engaged, the pin 21 on the housing 2 is fully inserted into the insertion hole 11 on the base 1. At this time, the locking block 3 is driven outward by the elastic element and forms a match with the locking groove 12 on the base 1, so that the housing 2 cannot move outward to the base 1, thereby locking the housing 2 on the base 1 and preventing the housing 2 from detaching from the base 1.

[0033] Optionally, the lower part of the locking block 3 is rotatably connected to the side of the housing 2 via a rotating shaft 31, and the elastic element is a torsion spring 32 fitted on the rotating shaft 31. When the torsion spring 32 is in its natural state, the locking block 3 protrudes from the side of the housing 2.

[0034] Specifically, such as Figure 4 and Figure 6 As shown, a connecting block protrudes from the lower part of the locking block 3, and a rotating shaft 31 is fixedly connected to the connecting block. The rotating shaft 31 is rotatably connected to the side of the housing 2. Figure 4 In the middle, the connecting block extends into the interior of the side of the housing 2 and is installed in a hidden manner. The elastic element is the torsion spring 32 fitted on the rotating shaft 31. The two sets of spring arms of the torsion spring 32 cooperate with the rotating shaft 31 and the housing 2 respectively, so that when the locking block 3 is in the first state mentioned above, the torsion spring 32 can be in a charged state. When the housing 2 is installed in place, the locking block 3 is aligned with the locking groove 12. At this time, the torsion spring 32 drives the locking block 3 to rotate into the locking groove 12, preventing the housing 2 from separating from the base 1.

[0035] Preferably, such as Figure 4 As shown, there are two sets of locking blocks 3, which are symmetrically arranged on both sides of the housing 2, so as to lock the housing 2 more stably on the base 1.

[0036] In another embodiment of this utility model, a guide groove 13 is also provided on the base 1. The width of the guide groove 13 is equal to the width of the locking block 3, and the guide groove 13 and the locking groove 12 are directly opposite each other. When the locking block 3 is in the retracted state, it protrudes from the side of the housing 2.

[0037] Specifically, such as Figure 2 and Figure 5As shown, a guide groove 13 is vertically formed on the base 1. The guide groove 13 is formed on the side wall of the recessed portion of the base 1. The locking groove 12 is directly opposite to and communicates with the guide groove 13. The depth of the locking groove 12 is greater than the depth of the guide groove 13, and the length of the locking groove 12 is less than the length of the guide groove 13. This allows the guide groove 13 to be set higher than the locking groove 12 in the vertical direction. In this embodiment, when the locking block 3 is in the first state, a portion of it protrudes from the side of the housing 2. With this configuration, when the housing 2 is recessed towards the base 1... During partial movement, the locking block 3 is blocked by the side wall of the recessed part on the base 1 and is in the first state. In this state, the locking block 3 and the guide groove 13 cooperate to guide the movement of the housing 2, so that the pin 21 can always be aligned with the socket 11. After the housing 2 has completely moved to the inside of the recessed part, the locking block 3 is aligned with the locking groove 12. At this time, the locking block 3 will rotate under the torque of the torsion spring 32 and cooperate with the locking groove 12, thereby locking the housing 2 on the base 1.

[0038] Furthermore, the housing 2 is also provided with an adjusting member 4 that can drive the locking block 3 from the second state to the first state.

[0039] Furthermore, the locking block 3 includes a side plate 301 and an arc-shaped plate 302 fixed to the side plate 301. The adjusting member 4 includes an adjusting rod 41 that passes through the arc-shaped plate 302. The adjusting rod 41 is slidably installed on both sides of the housing 2, and the adjusting rod 41 is provided with an inclined surface. When the adjusting rod 41 is driven to move towards the upper part of the housing 2, the inclined surface of the adjusting rod 41 contacts the arc-shaped plate 302 and pushes the arc-shaped plate 302 into the housing 2.

[0040] The adjusting rod 41 includes a first vertical section 411, an inclined section 412, and a second vertical section 413 connected in sequence. The width of the first vertical section 411 is smaller than the width of the second vertical section 413.

[0041] Specifically, in the above embodiments, although the rotation of the locking block 3 achieves guidance during the installation of the housing 2 and locking after installation, since the locking block 3 is completely hidden inside the contact area between the base 1 and the housing 2 after installation, it is inconvenient to release its lock on the housing 2 for disassembly and replacement. In this embodiment, an adjusting rod 41 is slidably mounted on the housing 2. When the housing 2 is installed in the base 1, the upper end of the adjusting rod 41 is above the base 1. Figure 6 As shown, the adjusting rod 41 includes a first vertical section 411, an inclined section 412, and a second vertical section 413 connected in sequence, wherein the width of the first vertical section 411 is ( Figure 4The dimension in the horizontal direction is smaller than the width of the second vertical rod; unlike the above embodiment, the locking block 3 includes a side plate 301 and an arc plate 302. The lower end of the side plate 301 is rotatably connected to the housing 2, and the arc plate 302 is fixed to the upper end of the side plate 301. The first vertical section 411 is provided through the arc plate 302, and the arc plate 302 is provided with an adjustment hole 3021 with a width not less than the width of the second vertical section 413.

[0042] When the adjusting rod 41 is in the initial state, the first vertical section 411 is in the adjusting hole 3021 opened on the arc plate 302. At this time, the locking block 3 is in the second state. When the adjusting rod 41 is driven to slide upward along the side wall of the housing 2 from the initial position, the inclined section 412 moves upward to correspond to the adjusting hole 3021 and pushes the arc plate 302 to make the side plate 301 rotate until the locking block 3 is adjusted from the second state to the first state, thereby releasing the lock on the housing 2, so as to facilitate the disassembly, inspection or replacement of the functional module; and since the adjusting rod 41 needs to move upward a certain distance to release the lock on the housing 2, it can prevent accidental unlocking.

[0043] Furthermore, a protrusion 42 is fixed to the upper end of the adjusting rod 41, and the protrusion 42 protrudes from the side of the housing 2.

[0044] Furthermore, a spring 23 is fixedly connected inside the housing 2. The upper end of the spring 23 is fixedly connected to the second vertical section 413. When the spring 23 is in its natural state, the first vertical section 411 is in the adjustment hole 3021.

[0045] Specifically, to facilitate the movement of the adjusting rod 41, a protrusion 42 is fixedly connected to the upper end of the adjusting rod 41, such as... Figure 4 and Figure 6 As shown, the protrusion 42 is fixedly connected to the end of the first vertical section 411 away from the inclined section 412, and the protrusion 42 protrudes from the side of the housing 2 so that the adjusting rod 41 can be pulled upward by hooking the protrusion 42 with a finger. To ensure that the adjusting rod 41 does not slip when the force is small, so as to maintain the locking effect of the locking block 3 on the housing 2; a spring 23 is also provided inside the housing 2, such as Figure 4 As shown, the lower end of the spring 23 is fixedly connected to the bottom inner wall of the mounting groove 22 opened on the housing 2, while the upper end of the spring 23 is fixedly connected to the surface of the second vertical section 413 of the adjusting rod 41 away from the inclined section 412. When the spring 23 is in its natural state, the first vertical section 411 is in the adjusting hole 3021. That is, when the spring 23 is in its natural state, the locking block 3 can keep the housing 2 locked. To pull the adjusting rod 41 up, it is necessary to overcome the elastic force of the spring 23 and the resistance of the arc plate 302 to the adjusting rod 41, so as to avoid accidental contact that would cause the housing 2 to be unlocked.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
