Patent Description:
To facilitate the replacement of failed components, a pluggable mechanism is adopted in the surge protector and includes a base and a pluggable module of the surge protector. Additionally, the surge protector adopts a clamping manner to facilitate assembly, which can improve assembly efficiency. To facilitate the insertion and removal operation, the cooperation of the protruding point/protruding edge and the groove is generally adopted. The insertion and removal of the pluggable module can be achieved by overcoming the resistance of the deformation of the housing when the pluggable module of the surge protector needs to be inserted and removed. Therefore, the deformation resistance of the housing is generally made to be small, resulting in an unstable assembly. That is, once the cooperation of the clamping fails, the two parts are easily separated from each other. <CIT> discloses a protector according to the preamble of independent claim <NUM>. The protector comprises an SPD plug and a jack board. The SPD plug and the jack board are electrically connected by engaging plug terminals on the SPD plug side with jack contacts on the jack board. When the SPD plug is inserted to the jack board, engaging recesses on the SPD plug side are engaged with engaging protrusions on the jack board side, therefore the SPD plug is fixed.

Given the above shortcomings in the prior art, an objective of the present disclosure is to provide a surge protector with an anti-off structure to achieve a more reliable and stable clamping manner.

To achieve the above objective, the present disclosure provides a surge protector with an anti-off structure, including a pluggable module and a base. The base includes a pluggable terminal connection part at a bottom of the base and an external terminal connection part on each of both sides of the base. A pluggable module installation slot is formed in the middle of the base to guide a pin of the pluggable module to insert into the pluggable terminal connection part. A top of the external terminal connection part of the base is provided with a sliding limit device, and each of both sides of the pluggable module is provided with a fixing limit device.

The direction of inserting the pluggable module into the base is defined as a downward direction.

The sliding limit device includes a hole cover, and the hole cover is slidably connected to the top of the external terminal connection part. When the pluggable module is completely inserted, a part of the hole cover protrudes into the pluggable module installation slot and is clamped with the fixing limit device of the pluggable module to limit the pluggable module from being detached from the base.

Further, preferably, the fixing limit device includes a limit protruding block, and a first side of the hole cover is provided with a first positioning rib, wherein the first side of the hole cover faces the pluggable module installation slot. In an anti-off state, the first positioning rib protrudes into the pluggable module installation slot and abuts the upper surface of the limit protruding block. In an unbuckled state, the first positioning rib slides to leave the pluggable module installation slot and separate from the limit protruding block.

Further, preferably, the sliding limit device further includes an elastic component. The hole cover is slidably connected to the top of the external terminal connection part. Both ends of the elastic component abut the hole cover and the top of the external terminal connection part, respectively, such that the elastic component has an acting force to constantly drive the hole cover to slide horizontally toward the pluggable module installation slot.

Further, preferably, the top of the external terminal connection part is provided with a receiving slot configured to place the elastic component, and both ends of the elastic component abut the first positioning rib and a sidewall of the receiving slot, respectively.

Further, preferably, the upper edge of the limit protruding block is provided with a protrusion. When the pluggable module is inserted, the hole cover is slid to form a clamping between the first positioning rib of the hole cover and the protrusion to prevent the hole cover from returning. When the pluggable module is prepared to be removed, the hole cover is slid to overcome the resistance of the clamping between the first positioning rib and the protrusion to allow the hole cover to separate from the limit protruding block.

Further, preferably, the fixing limit device further includes a limit shaft, and the first side of the hole cover is provided with a limit slot. In the anti-off state, the limit shaft is clamped with the limit slot. In the unbuckled state, the limit shaft is separated from the limit slot.

Further, preferably, a second side of the hole cover is provided with a second positioning rib, wherein the second side of the hole cover is away from the pluggable module installation slot. A side of the top of the external terminal connection part is provided with a first limit edge portion and a second limit edge portion, where the side of the top of the external terminal connection part is away from the pluggable module installation slot, and the first limit edge portion and the second limit edge portion are configured to be clamped with the second positioning rib for position limiting. The second limit edge portion is located on the outer side of the first limit edge portion. When the second positioning rib of the hole cover is clamped with the first limit edge portion, the first positioning rib of the hole cover protrudes into the pluggable module installation slot to form the anti-off state. When the second positioning rib of the hole cover is clamped with the second limit edge portion, the first positioning rib of the hole cover leaves the pluggable module installation slot to form the unbuckled state.

Further, preferably, the top of the external terminal connection part is provided with a hole cover sliding slot, and the hole cover is provided with a structure corresponding to the hole cover sliding slot, such that the hole cover is allowed to slide horizontally at the top of the external terminal connection part.

Further, preferably, an upper surface of the hole cover is provided with an action part, and the action part is configured to be operated manually to move the hole cover away from the pluggable module installation slot.

Further, preferably, a lower surface of the limit protruding block is an inclined surface, and the inclined surface is configured to push away the hole cover when the pluggable module is inserted into the pluggable module installation slot.

Compared with the prior art, the advantages of the present disclosure are as follows:
According to the present disclosure, the anti-off function of the surge protector is achieved through the cooperation of slidable hole covers arranged at the tops of both sides of the base of the surge protector and the limit protruding blocks arranged on both sides of the pluggable module. Specifically, when the pluggable module of the surge protector is completely inserted into the base, a part of the hole cover slides to protrude into the pluggable module installation slot and abuts the upper surface of the limit protruding block, to prevent the pluggable module from being detached from the base. When the pluggable module is removed, the part of the hole cover previously protruding into the pluggable module installation slot is returned through sliding, thereby separating from the limit protruding block to allow the pluggable module to be freely removed from the base. 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.

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.

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

As shown in <FIG>, the present disclosure discloses a specific embodiment of a surge protector, including the base <NUM> and the pluggable module <NUM>. The surge protector is provided with an anti-off structure to prevent the well-placed pluggable module <NUM> from being detached from the base <NUM>. The explanation is as follows:
In the embodiment, the base <NUM> includes the U-shaped base body <NUM>, a pair of springs <NUM>, and a pair of hole covers <NUM>.

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

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

Two ends of the hole cover <NUM> bend downward to form the first positioning rib <NUM> and the second positioning rib <NUM>. The hole cover <NUM> is further provided with a structure corresponding to the hole cover sliding slot <NUM>, such that the hole cover <NUM> is allowed to slide horizontally at the top of the external terminal connection part.

The spring <NUM> is arranged in the spring receiving slot <NUM>. One end of the spring <NUM> abuts the side of the spring receiving slot <NUM>, and the other end of the spring <NUM> abuts the first positioning rib <NUM> of the hole cover <NUM>, such that the spring <NUM> has an acting force to constantly drive the hole cover <NUM> to slide horizontally toward the pluggable module installation slot <NUM>.

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

In the embodiment, the pluggable module <NUM> includes the pluggable module housing <NUM>, the limit protruding blocks <NUM> and the guide bars <NUM> arranged on two side surfaces of the pluggable module housing <NUM>, the first pin <NUM> and the second pin <NUM> configured to electrically connect the pluggable module <NUM>, and the pluggable terminal connection part of the base <NUM>.

In an anti-off state, the first positioning rib <NUM> of the hole cover <NUM> protrudes into the pluggable module installation slot <NUM> of the base <NUM> and abuts the upper surface of the limit protruding block <NUM> of the pluggable module <NUM> to limit the pluggable module <NUM> to move upward for removing from the pluggable module installation slot <NUM> of the base <NUM>.

In an unbuckled state, the hole cover <NUM> moves away from the pluggable module installation slot <NUM>, the second positioning rib <NUM> moves to be clamped with the second limit edge portion <NUM>, such that the first positioning rib <NUM> of the hole cover <NUM> leaves the pluggable module installation slot <NUM>, thereby separating from the upper surface of the limit protruding block <NUM> of the pluggable module <NUM> and releasing the limitation on the removal of the pluggable module <NUM> from the base <NUM>.

The upper surface of the limit protruding block <NUM> defines a planar or an approximately planar surface. The lower surface of the limit protruding block <NUM> is an inclined surface, and the angle between the inclined surface and the side surface of the pluggable module is <NUM>°-<NUM>°.

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

In the embodiment, the pluggable module <NUM> is further provided with the limit shaft <NUM>. The side of the hole cover <NUM> facing the pluggable module installation slot <NUM> is provided with the limit slot <NUM>, and the opening of the limit slot <NUM> faces the pluggable module installation slot <NUM>. In the anti-off state, the limit shaft <NUM> is clamped with the limit slot <NUM>. In the unbuckled state, the limit shaft <NUM> is separated from the limit slot <NUM>.

In the embodiment, to facilitate the sliding of the hole cover <NUM> when the pluggable module <NUM> is removed, the upper surface of the hole cover is provided with the action part <NUM>. Specifically, the action part <NUM> is a protruding structure. The operator can exert force through the action part <NUM> to drive the hole cover <NUM> to slide to the outer side to achieve the unbuckled state. Specifically, the structure of the action part <NUM> 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.

In the embodiment, to avoid affecting the setting of the sliding limit device, the guide slots <NUM> of the pluggable module installation slot <NUM> are arranged at both side edges of the pluggable module installation slot <NUM>, and correspondingly, both side edges of the pluggable module <NUM> are provided with the guide bars <NUM> to guide the pluggable module to insert into the pluggable module installation slot <NUM>.

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.

As shown in <FIG>, the present disclosure discloses another embodiment of the surge protector. The difference between this embodiment and Embodiment <NUM> is the clamping manner of the hole cover <NUM> and the pluggable module <NUM>.

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