Description

Fastener and assembly using same

Technical Field

The present invention relates to a buckle and an assembly using the same, and more particularly, to a bi-directional engaging buckle and an assembly using the same.

Background

In electronic devices, the performance of processors is higher and higher, the generated heat energy is more and more, and the heat dissipation requirements of electronic devices are increased. A heat sink may be provided to dissipate heat generated by the processor. The heat sink may be disposed on the processor, and the heat sink may be fixed to the circuit board on which the processor is disposed by using bolts in combination with elastic members such as springs.

However, the elastic force of the elastic member cannot completely fix the heat sink and the circuit board. Therefore, when the electronic device is subjected to vibration or impact, the heat sink abutted by the elastic member may shake relative to the circuit board. Also, the sloshing heat sink may hit the disposer, causing damage to the disposer.

Disclosure of Invention

In view of the above problems, the present invention provides a buckle and an assembly using the buckle, so as to solve the problem of impact caused by the shaking of an incompletely fixed buckled object.

An embodiment of the present invention provides a buckle, which includes a hollow cylinder and a pin. The hollow column body comprises a first combining part and a second combining part which are opposite. The hollow column body is surrounded with an insertion hole which penetrates through the first combining part and the second combining part. The plug pin is inserted in the jack and can move between a first insertion position and a second insertion position. When the bolt moves along the direction of the first combining part towards the second combining part and moves from the first inserting position to the second inserting position, the bolt props up the second combining part, and the outer edge size of the second combining part when the bolt is positioned at the first inserting position is smaller than that of the second combining part when the bolt is positioned at the second inserting position.

An embodiment of the invention provides an assembly, which includes a fastened object and a fastener. The buckled object is provided with a through hole. The buckle comprises a hollow cylinder and a bolt. The hollow column body comprises a first combining part and a second combining part which are opposite. The hollow column body is surrounded with an insertion hole which penetrates through the first combining part and the second combining part. The first connecting portion penetrates through the through hole. The plug pin is inserted in the jack and can move between a first insertion position and a second insertion position. When the bolt moves along the direction of the first combining part towards the second combining part and moves from the first inserting position to the second inserting position, the bolt props up the second combining part, and the outer edge size of the second combining part when the bolt is positioned at the first inserting position is smaller than that of the second combining part when the bolt is positioned at the second inserting position.

According to the buckle of the embodiment of the invention, the buckled object and the object to be buckled can be respectively fixed in two directions through the first combining part and the second combining part of the central column body, so that the buckled object is prevented from shaking under the condition of no elastic piece, and the buckled object is further prevented from impacting the object to be buckled or an element arranged on the object to be buckled.

In addition, the buckle and the buckled object can be combined into an assembly through the first combining part. When the bolt is moved to the second insertion position, the bolt props the second combining part, and the outer edge size of the second combining part when the bolt is positioned at the first insertion position is smaller than that of the second combining part when the bolt is positioned at the second insertion position. Therefore, the second combining part of the buckle can retract when the bolt is positioned at the first insertion position, and is easy to be arranged on an object to be buckled. The second combining part of the buckle can be expanded outwards when the bolt is positioned at the second inserting position and is clamped with the object to be buckled.

The foregoing description of the present invention and the following detailed description are presented to illustrate and explain the principles and spirit of the invention and to provide further explanation of the invention as claimed.

The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

In the drawings, the size, proportion, angle and the like of the drawings are exaggerated for illustrative purposes, but the invention is not limited thereto. Various modifications can be made without departing from the spirit of the invention. The term "substantially" as used herein may refer to deviations caused by tolerances in manufacturing or errors in measurement.

Referring to fig. 1 and 2, fig. 1 is a schematic perspective view illustrating an assembly 10 installed on an object to be fastened according to an embodiment of the present invention, and fig. 2 is a schematic perspective view illustrating the assembly 10 of fig. 1. In the present embodiment, the assembly 10 can be installed on the object 9 to be fastened having the first through hole 90. The object to be fastened 9 may for example be provided with a clip 8. The assembly 10 includes a buckled article 11 and a buckle 12. The clamping device 8 can be located between the object to be fastened 11 and the object to be fastened 9. The buckle 12 includes a hollow cylinder 121 and a latch 122. The buckled object 11 is fixed on the buckled object 9 through the matching of the hollow cylinder 121 of the buckle 12 and the bolt 122. In the present embodiment, the object to be fastened 9 may be a circuit board, the object to be fastened 11 may be a heat sink, and the clamping device 8 may be a processor. However, the object to be fastened 9, the object to be fastened 11 and the clip 8 are not limited thereto. The object 9 to be fastened may also be a heat sink or other element, for example. The fastened object 11 may be a circuit board or other components. The clamping member 8 may also be a heat-generating chip, a heat-conducting element, a heat-conducting glue or a combination thereof.

Referring to fig. 3 and 4, fig. 3 is a perspective exploded view of the assembly 10 of fig. 2, and fig. 4 is a side exploded view of the assembly of fig. 2. The fastened object 11 has a second through hole 110.

The hollow cylinder 121 of the buckle 12 includes a first coupling portion 1211, a second coupling portion 1212, and a bearing protrusion 1213. The first and

second bonding portions

1211 and 1212 are located on opposite sides of the carrying protrusion 1213. The hollow cylinder 121 surrounds an insertion hole 121a, and the insertion hole 121a penetrates the first combining portion 1211, the second combining portion 1212 and the bearing protrusion 1213. The hollow cylinder 121 has a positioning groove 121b on a side thereof adjacent to the insertion hole 121 a.

The first combining portion 1211 includes two engaging members 12110 separated from each other. The engaging pieces 12110 are arranged around the central axis C of the insertion hole 121 a. Each engaging member 12110 has an engaging projection 1211a on a side away from the insertion hole 121 a. The engaging protrusions 1211a have a first guiding surface 1211b on a side away from the insertion hole 121 a. The first guide surface 1211b gradually approaches the central axis C of the insertion hole 121a in a direction from the second coupling portion 1212 toward the first coupling portion 1211. Therefore, when the first combining portion 1211 is inserted into the second through hole 110 in a direction from the lower surface 11a to the upper surface 11b of the fastened object 11, the fastened object 11 can push the engaging protrusion 1211a along the first guiding surface 1211b to retract the engaging member 12110, such that the engaging member 12110 passes through the second through hole 110. When the engaging protrusion 1211a passes through the second through hole 110, the engaging member 12110 can return to its original shape and engage with the object 11.

It should be noted that, in the embodiment, the number of the engaging elements 12110 is two, but not limited thereto. In other embodiments, the number of engaging elements 12110 may be other.

The second coupling portion 1212 includes four flexible arms 12120 separated from each other. The flexible arms 12120 are aligned around the central axis C of the insertion hole 121 a. The side of each flexible arm 12120 adjacent to the receptacle 121a has an abutting projection 1212 a. The side of each abutting protrusion 1212a close to the insertion hole 121a has a second guiding surface 1212 b. The second guide surface 1212b gradually approaches the central axis C of the insertion hole 121a in a direction from the first combining portion 1211 toward the second combining portion 1212. The plurality of abutting protrusions 1212a have an inner diameter D1 therebetween. In the present embodiment, the number of the flexible arms 12120 is four, but the invention is not limited thereto. In other embodiments, the number of flexible arms 12120 can be other numbers.

The distance S between the bearing protrusion 1213 and the engaging bump 1211a can be set according to the local thickness T1 from the lower surface 11a to the upper surface 11b of the fastened object 11. The thickness T2 of the supporting protrusion 1213 can be set according to the thickness T3 of the clip 8 to be clamped between the lower surface 11a of the object 11 to be fastened and the object 9 to be fastened.

The pin 122 has a first end 122a and a second end 122b opposite to each other. When the plug 122 is inserted into the insertion hole 121a of the hollow cylinder 121 along the direction from the first combining portion 1211 to the second combining portion 1212 of the hollow cylinder 121, the first end 122a of the plug 122 can move in the insertion hole 121a, and the second end 122b can move outside the insertion hole 121 a. The latch 122 has a positioning rib 1221 between the first end 122a and the second end 122 b. The pin 122 has an outer diameter D2 at the first end 122 a. The outer diameter D2 is larger than the inner diameter D1 of the abutting protrusions 1212 a. In the embodiment, the latch 122 has a positioning rib 1221, but not limited thereto. In other embodiments, the number of the positioning ribs 1221 may be other numbers.

In addition, in the present embodiment, the second end 122b of the plug 122 further has a cover 1222.

The plug 122 is movable relative to the hollow cylinder 121 between a first insertion position and a second insertion position. When the latch 122 is at the first insertion position, the positioning rib 1221 of the latch 122 can be engaged with the positioning groove 121b of the hollow cylinder 121. When the latch 122 moves along the direction from the first combining portion to the second combining portion and moves from the first insertion position to the second insertion position, the positioning rib 1221 may be separated from the positioning groove 121b, and the first end 122a of the latch 122 may gradually prop open the flexible arms 12120 of the second combining portion 1212 along the second guiding surface 1212b of each abutting protrusion 1212a, so that the flexible arms 12120 elastically deform outward. In other words, when the plug pin 122 is at the first insertion position, the second combining portion 1212 has a smaller first outer edge dimension W1, and when the plug pin 122 is at the second insertion position, the second combining portion 1212 has a larger second outer edge dimension W2.

In addition, when the plug 122 is at the second insertion position, the cover 1222 of the plug 122 covers and shields at least a portion of the first combining portion 1211 of the hollow cylinder 121, thereby achieving an aesthetic effect.

Referring to fig. 5 and 6, a side view of the assembly process of the assembly 10 of fig. 2 is shown. As shown in fig. 5, when the buckle 12 is to be installed on the buckled object 11, the hollow cylinder 121 and the plug 122 of the buckle 12 are separated. The first coupling portion 1211 of the hollow cylinder 121 is engaged with the second through hole 110 of the object 11. For example, the engaging element 12110 of the first combining portion 1211 can be inserted into the second through hole 110 from the lower surface 11a of the fastened object 11 to the upper surface 11b, and the fastened object 11 can push the engaging protrusion 1211a of the engaging element 12110 along the first guiding surface 1211b to retract the engaging element 12110, such that the engaging protrusion 1211a passes through the second through hole 110. When the bearing protrusion 1213 contacts the lower surface 11a of the object 11, the engaging element 12110 can return to its original shape, and the engaging protrusion 1211a and the object 11 interfere with each other to engage with each other. The article 11 and the first connection portion 1211 are located on the same side of the supporting protrusion 1213, and the article 11 is located between the engaging protrusion 1211a and the supporting protrusion 1213. Thereby stably fixing the buckled object 11 and the hollow cylinder 121.

As shown in fig. 6, the plug 122 can be inserted into the insertion hole 121a of the hollow cylinder 121 to reach the first insertion position. When the latch 122 is at the first insertion position, the positioning rib 1221 of the latch 122 is engaged with the positioning groove 121b of the hollow cylinder 121. Accordingly, the assembly of the assembly 10 is completed. At this time, the positioning rib 1221 is engaged with the positioning groove 121b, so that the latch 122 is prevented from being lost easily. Before the assembly 10 is mounted on the to-be-buckled object 9, the latch 122 can be maintained at the first insertion position by engaging the positioning rib 1221 with the positioning groove 121 b. Since the flexible arms 12120 of the second connecting portion 1212 are not spread, the second connecting portion 1212 has a smaller first outer edge dimension W1 and can be easily mounted on the object 9 to be buckled.

Referring to fig. 7 and 8, a side view of an exemplary assembly process of the assembly 10 of fig. 6 is shown. As shown in fig. 7, the assembly 10 is mounted on the object 9 to be fastened after the plug 122 is at the first insertion position. At this time, the flexible arms 12120 of the second combining portion 1212 of the hollow cylinder 121 are not yet expanded, so the first outer edge dimension W1 of the second combining portion 1212 is smaller than the inner diameter D3 of the first through hole 90 of the object to be buckled 9, so that the second combining portion 1212 can be inserted into the first through hole 90 of the object to be buckled 9.

Next, as shown in fig. 8, the plug 122 is moved to the second insertion position to spread the flexible arms 12120 of the second coupling portion 1212 of the hollow cylinder 121, so that the flexible arms 12120 are elastically deformed outward. The outer side of the second combining portion 1212 can abut against the inner wall of the first through hole 90 of the object 9 to be buckled. Also, the second bonding portion 1212 at this time has a second outer dimension W2. The second outer dimension W2 of the second combining portion 1212 is larger than the inner diameter D3 of the first through hole 90 of the object 9 to be buckled. The carrying protrusion 1213 may contact the object 9 to be clipped, and the thickness T2 of the carrying protrusion 1213 may be substantially the same as the thickness T3 of the clip 8.

By the second outer edge dimension W2 of the second combining portion 1212 being larger than the inner diameter D3 of the first through hole 90 of the object to be buckled 9, the assembly 10 can fix the buckled object 11 of the assembly 10 to the object to be buckled 9 without an elastic element, and can prevent the buckled object 11 from shaking relative to the object to be buckled 9. Therefore, the assembly 10 can provide good assembly stability.

In addition, the thickness T2 of the bearing protrusion 1213 can maintain the space between the article 11 to be fastened and the article 9 to be fastened, so as to prevent the article 11 to be fastened and the article 9 to be fastened from excessively pressing the clip 8, and prevent the article 11 to be fastened or the article 9 to be fastened from being deformed due to the fastening force of the second connecting portion 1212. Thus, the bearing projection 1213 functions as a spacer, but the number of components can be saved without additionally providing a spacer.

Furthermore, since the buckled object 11 and the hollow cylinder 121 are different elements, different types of buckled objects 11 can be replaced according to requirements. In addition, the hollow cylinder 121 can be replaced if it is worn by friction. Therefore, when there is a need for replacement, it is not necessary to replace multiple components together, so that the cost can be saved.

In addition, the cap 1222 covers the first coupling portion 1211 of the hollow cylinder 121, thereby achieving an aesthetic effect.

Referring to fig. 9 and 10, fig. 9 is a side view of an assembly 20 according to another embodiment of the invention, and fig. 10 is a perspective view of an application example of the assembly 20 of fig. 9. The assembly 20 of this embodiment is similar to the assembly 10 shown in fig. 5. However, the pin 222 of the assembly 20 of the present embodiment is different from the pin 122 of the assembly 10 shown in FIG. 5. The pin 222 has a first positioning rib 2221a closer to the first end 222a and a second positioning rib 2221b closer to the second end 222b between the first end 222a and the second end 222 b.

As shown in fig. 9, when the plug 222 is at the first insertion position, the first positioning rib 2221a is engaged with the positioning groove 121b of the hollow cylinder 121, and the second positioning rib 2221b is disengaged from the positioning groove 121 b.

As shown in fig. 10, the second combining portion 1212 is inserted into the first through hole 90 of the object 9 to be buckled, and the plug 222 is moved to the second insertion position. At this time, the first positioning rib 2221a is disengaged from the positioning groove 121b, the plug 222 expands the second connecting portion 1212, and the second positioning rib 2221b is engaged with the positioning groove 121 b. Thereby allowing the pin 222 to be easily maintained in the second insertion position.

In summary, in the buckle according to the embodiment of the invention, the buckled object and the object to be buckled are respectively fixed in two directions by the first combining portion and the second combining portion of the central cylinder, so that the buckled object is prevented from shaking without an elastic member, and the buckled object is prevented from impacting the object to be buckled or the clamped member between the buckled object and the object to be buckled. Wherein, the buckle and the buckled object are combined into an assembly through the first combining part. When the bolt is moved to the second insertion position, the bolt props the second combining part, and the outer edge size of the second combining part when the bolt is positioned at the first insertion position is smaller than that of the second combining part when the bolt is positioned at the second insertion position. Therefore, the second combining part of the buckle retracts when the bolt is positioned at the first inserting position, and is easy to be arranged on the object to be buckled. The second combining part of the buckle expands outwards when the bolt is positioned at the second inserting position and is clamped with the object to be buckled.

In addition, the interval between the fastened object and the object to be fastened is maintained through the thickness of the bearing convex part, so that the fastened object and the object to be fastened can be prevented from excessively extruding the clamping piece between the fastened object and the object to be fastened, and the fastened object or the object to be fastened can be prevented from being deformed due to the clamping force of the second combining part. Therefore, the bearing convex part has the function of a gasket, but the gasket does not need to be additionally arranged, so that the number of elements can be saved.

In addition, the positioning convex rib is clamped in the positioning groove, so that the bolt can be prevented from being lost easily. Moreover, the positioning relationship between the positioning convex rib and the positioning concave groove can also be used for assisting the bolt to be actually in the expected first insertion position or the expected second insertion position at the expected time point.

Furthermore, because the buckled object and the hollow column body belong to different elements, the buckled object with different types can be replaced according to requirements. In addition, if the hollow cylinder is worn due to friction, it can be replaced. Therefore, when there is a need for replacement, it is not necessary to replace multiple components together, so that the cost can be saved.

Although the present invention has been described with reference to the above embodiments, it is not intended to limit the invention. Variations and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. With regard to the scope of protection defined by the present invention, reference should be made to the appended claims.
