With reference to these contents, those having ordinary skills in the art should be able to understand other possible embodiments and the advantages of the present disclosure. The components in the drawings are not drawn in proportion, and similar component symbols are often used to represent similar components.

[0032] The present disclosure is further explained in combination with the drawings and the specific embodiments.

Embodiment 1

[0033] As shown in FIGS. 1-8, the present disclosure discloses a specific embodiment of a surge protector, including the base 1 and the pluggable module 2. The surge protector is provided with an anti-off structure to prevent the well-placed pluggable module 2 from being detached from the base 1. The explanation is as follows:

[0034] In the embodiment, the base 1 includes the U-shaped base body 11, a pair of springs 12, and a pair of hole covers 13.

[0035] The base body 11 includes the pluggable terminal connection part at the bottom and the external terminal connection parts on both sides. The pluggable module installation slot 14 is formed in the middle of the base body 11 to guide the pin of the pluggable module 2 to insert into the pluggable terminal connection part. Each of the external terminal connection parts on both sides of the base body 11 is provided with the screw operation hole 111 downward from the top.

[0036] The pair of hole covers 13 are respectively arranged at the tops of the external terminal connection parts on both sides of the base body 11. The through hole 135 is formed in the middle of the hole cover 13, and the through hole 135 is communicated with the screw operation hole 111, such that the setting of the hole cover 13 does not affect the screwdriver to extend into the screw operation hole 111 to connect the external terminal. The top of the external terminal connection part is provided with the spring receiving slot 112, the hole cover sliding slot 113, the first limit edge portion 114, and the second limit edge portion 115 to connect to the sliding limit device formed by the spring 12 and the hole cover 13. Specifically, the second limit edge portion 115 is arranged on the outer side of the first limit edge portion 114. Both sides of the pluggable module installation slot 14 are further provided with the guide slots 116.

[0037] Two ends of the hole cover 13 bend downward to form the first positioning rib 131 and the second positioning rib 132. The hole cover 13 is further provided with a structure corresponding to the hole cover sliding slot 113, such that the hole cover 13 is allowed to slide horizontally at the top of the external terminal connection part.

[0038] The spring 12 is arranged in the spring receiving slot 112. One end of the spring 12 abuts the side of the spring receiving slot 112, and the other end of the spring 12 abuts the first positioning rib 131 of the hole cover 13, such that the spring 12 has an acting force to constantly drive the hole cover 13 to slide horizontally toward the pluggable module installation slot 14.

[0039] To limit the sliding of the hole cover 13, the second positioning rib 132 of the hole cover 13 is clamped with the first limit edge portion 114 or the second limit edge portion 115 on the outer side (that is, away from the pluggable module installation slot 14) of the top of the external terminal connection part to form an anti-off state or an unbuckled state. The second limit edge portion 115 is located on the outer side of the first limit edge portion 114.

[0040] In the embodiment, the pluggable module 2 includes the pluggable module housing 21, the limit protruding blocks 22 and the guide bars 23 arranged on two side surfaces of the pluggable module housing 21, the first pin 24 and the second pin 25 configured to electrically connect the pluggable module 2, and the pluggable terminal connection part of the base 1.

[0041] In an anti-off state, the first positioning rib 131 of the hole cover 13 protrudes into the pluggable module installation slot 14 of the base 1 and abuts the upper surface of the limit protruding block 22 of the pluggable module 2 to limit the pluggable module 2 to move upward for removing from the pluggable module installation slot 14 of the base 1. See FIGS. 5-6.

[0042] In an unbuckled state, the hole cover 13 moves away from the pluggable module installation slot 14, the second positioning rib 132 moves to be clamped with the second limit edge portion 115, such that the first positioning rib 131 of the hole cover 13 leaves the pluggable module installation slot 14, thereby separating from the upper surface of the limit protruding block 22 of the pluggable module 2 and releasing the limitation on the removal of the pluggable module 2 from the base 1. See FIGS. 7-8.

[0043] The upper surface of the limit protruding block 22 defines a planar or an approximately planar surface. The lower surface of the limit protruding block 22 is an inclined surface, and the angle between the inclined surface and the side surface of the pluggable module is 135°-150°.

[0044] When the pluggable module 2 is inserted, the limit protruding blocks 22 of the pluggable module 2 can push away the hole covers 13 through the inclined surfaces, such that the pins of the pluggable module 2 are completely inserted into the base 1. When the pins of the pluggable module 2 are already completely inserted into the base, the limit protruding blocks 22 move to be located below the hole covers 13, and the hole covers 13 move horizontally to be located above the limit protruding blocks 22 under the action of the springs 12 and abut the upper surfaces of the limit protruding blocks 22. At the same time, the anti-off state is maintained under the action of the springs 12 to achieve a reliable connection. When the pluggable module 2 needs to be removed from the base 1, the hole covers 13 on both sides are manually moved toward both sides, and then the second positioning ribs 132 of the hole covers 13 are clamped with the second limit edge portions 115, such that the first positioning ribs 131 of the hole covers 13 on both sides leave the pluggable module installation slot 14 to form the unbuckled state. At this time, the pluggable module 2 can be freely removed from the base 1.

[0045] In the embodiment, the pluggable module 2 is further provided with the limit shaft 26. The side of the hole cover 13 facing the pluggable module installation slot 14 is provided with the limit slot 133, and the opening of the limit slot 133 faces the pluggable module installation slot 14. In the anti-off state, the limit shaft 26 is clamped with the limit slot 133. In the unbuckled state, the limit shaft 26 is separated from the limit slot 133.

[0046] In the embodiment, to facilitate the sliding of the hole cover 13 when the pluggable module 2 is removed, the upper surface of the hole cover is provided with the action part 134. Specifically, the action part 134 is a protruding structure. The operator can exert force through the action part 134 to drive the hole cover 13 to slide to the outer side to achieve the unbuckled state. Specifically, the structure of the action part 134 includes, but is not limited, to a protrusion, a ridge, a groove, etc., as long as it is convenient for the operator to exert force.

[0047] In the embodiment, to avoid affecting the setting of the sliding limit device, the guide slots 116 of the pluggable module installation slot 14 are arranged at both side edges of the pluggable module installation slot 14, and correspondingly, both side edges of the pluggable module 2 are provided with the guide bars 23 to guide the pluggable module to insert into the pluggable module installation slot 14.

[0048] In the embodiment, the anti-off function of the surge protector is achieved by the cooperation of the slidable hole covers and the springs arranged at the tops of the external terminal connection parts on both sides of the base of the surge protector, and the limit protruding blocks arranged on both sides of the pluggable module. The structure is stable and reliable, and the pluggable module cannot be pulled out from the base when the anti-off structure is not unbuckled.

Embodiment 2

[0049] As shown in FIGS. 9 and 10, the present disclosure discloses another embodiment of the surge protector. The difference between this embodiment and Embodiment 1 is the clamping manner of the hole cover 13 and the pluggable module 2.

[0050] In the embodiment, the upper edge of the limit protruding block 22 of the pluggable module 2 is provided with the protrusion 221, and no spring is arranged between the hole cover 13 and the base body 11, such that the inward and outward sliding of the hole cover 13 requires manual operation. When the pluggable module 2 is inserted, the first positioning rib 131 of the hole cover 13 is clamped with the protrusion 221 by manually sliding the hole cover 13 to prevent the hole cover 13 from returning. Therefore, the anti-off state is maintained to achieve a reliable connection.

[0051] In the embodiment, the anti-off function of the surge protector is achieved by the cooperation of the slidable hole covers arranged at the tops of the external terminal connection parts on both sides of the base of the surge protector, the limit protruding blocks arranged on both sides of the pluggable module and the protrusions arranged on the upper edges of the limit protruding blocks. The structure is stable and reliable, and the pluggable module cannot be pulled out from the base when the anti-off structure is not unbuckled.

[0052] Although the present disclosure is specifically demonstrated and introduced in conjunction with the preferred implementation solutions, those skilled in the art should understand that without departing from the spirit and scope of the present disclosure as defined in the appended claims, various changes may be made to the present disclosure in forms and details, which all shall fall within the scope of protection of the present disclosure.

[0053] The terms “an embodiment,” “embodiments,” or “one or more embodiments” in this text mean that a particular feature, structure, or characteristic described in combination with the embodiments is included in at least one embodiment of the present disclosure. Furthermore, it should be noted that the term “in the embodiment” here does not necessarily all refer to the same embodiment.
