Description
本創作係關於用於將外蓋鎖固至底層結構之連接器系統的領域,且特定言之,係關於用於將護罩鎖固至設備殼體及類似物之護罩閂鎖。This creation relates to the field of connector systems for locking an outer cover to an underlying structure, and in particular, to a shroud latch for locking a shroud to a device housing and the like.
為鎖固外蓋以封裝或部分地封裝多種設備而提供連接器係一種普遍的需求。舉例而言,電腦及電子設備通常被安裝在具有一或多個可拆卸的護罩的盒狀外殼內,該等護罩覆蓋外殼之一部分。此等護罩常常由安裝在護罩上之連接器來鎖固,該連接器與自殼體伸出之銷接合。連接器與銷接合,且例如藉由拉動在殼體之對應邊緣下的護罩之邊緣,使連接器閉合在銷上施加拉力,從而牽拉護罩而使其與殼體鎖固。It is a common need to provide connectors for locking the cover to package or partially package a variety of devices. For example, computer and electronic devices are typically mounted in a box-like housing having one or more removable covers that cover a portion of the housing. These shrouds are often locked by a connector mounted on a shroud that engages a pin that extends from the housing. The connector engages the pin and, for example, by pulling the edge of the shroud under the corresponding edge of the housing, the connector closes to exert a pulling force on the pin, thereby pulling the shroud to lock it with the housing.
在圖1至圖3C中展示了此類型之連接器之一實例,該等圖展示了具有杯形件102、滑塊104及槓桿106的閂鎖100。滑塊104係可移動地安裝至杯形件102,使滑塊104能夠在閂鎖位置與解鎖位置之間移動(圖2)。滑塊104係藉由被限制在杯形件102的底部表面與自杯形件側壁伸出的滑塊保持器108 (例如,銷、肋或類似物)之間,而被可移動地安裝至杯形件102,但可以使用其他配置。槓桿106藉由一或多個槓桿銷110而以樞轉方式安裝至杯形件102,該一或多個槓桿銷裝配至槓桿106中之對應孔112及杯形件102中之對應孔114內。該等槓桿銷110形成一樞轉式連接,其使槓桿106能夠在打開位置與關閉位置之間旋轉。One example of a connector of this type is shown in Figures 1 through 3C, which show a latch 100 having a cup 102, a slider 104, and a lever 106. The slider 104 is movably mounted to the cup 102 to enable the slider 104 to move between a latched position and an unlocked position (Fig. 2). The slider 104 is movably mounted to the slider holder 108 (eg, pin, rib or the like) that is confined to the bottom surface of the cup 102 and extends from the sidewall of the cup to Cup 102, but other configurations can be used. The lever 106 is pivotally mounted to the cup 102 by one or more lever pins 110 that fit into corresponding holes 112 in the lever 106 and corresponding holes 114 in the cup 102 . The lever pins 110 form a pivotal connection that enables the lever 106 to rotate between an open position and a closed position.
槓桿106藉由一或多個滑塊銷116而可操作地連接至滑塊104。滑塊銷116在偏離槓桿銷110之旋轉軸線的位置處(例如,孔119處)固定至槓桿106,且穿過滑塊104中之槽118。如此在槓桿106與滑塊104之間提供一驅動式連接,在該驅動式連接中,槓桿106在打開位置與關閉位置之間的旋轉引起滑塊104沿著杯形件102在解鎖位置與閂鎖位置之間移動。在其他實施例中可使用其他操作性連接(例如,凸輪表面或類似物)。The lever 106 is operatively coupled to the slider 104 by one or more slider pins 116. The slider pin 116 is fixed to the lever 106 at a position offset from the rotational axis of the lever pin 110 (eg, at the hole 119) and passes through the slot 118 in the slider 104. This provides a drive connection between the lever 106 and the slider 104, in which the rotation of the lever 106 between the open position and the closed position causes the slider 104 to be in the unlocked position and latch along the cup 102. Move between lock positions. Other operative connections (e.g., cam surfaces or the like) may be used in other embodiments.
杯形件102經結構設計為安裝至護罩、門或其他封閉結構。舉例而言,杯形件102可具有下表面120、自下表面120向上延伸的側壁122以及處於側壁122之頂部的凸緣124。(應理解,表示空間中之相對位置的術語,諸如「下」及「上」僅用來幫助解釋實施例,而非旨在要求實施例在空間中具有一特定定向)。凸緣124可具有一或多個螺孔126,以用於將杯形件102緊固至護罩,但可使用杯形件102與護罩之間的其他連接方式。在一個實施例中,杯形件102經安裝至護罩之底側(例如,多個螺絲向上穿過螺孔126,以將杯形件102鎖固至位於杯形件102上方的護罩)。在另一實施例中,凸緣124可安置在護罩的上側,而杯形件102之其餘部分穿過護罩中之開口突出。The cup 102 is structurally designed to be mounted to a shroud, door or other enclosed structure. For example, the cup 102 can have a lower surface 120, a sidewall 122 that extends upwardly from the lower surface 120, and a flange 124 that is at the top of the sidewall 122. (It should be understood that terms referring to relative positions in space, such as "lower" and "upper" are used merely to help explain the embodiments, and are not intended to require that the embodiments have a particular orientation in the space. The flange 124 can have one or more threaded holes 126 for securing the cup 102 to the shroud, although other connections between the cup 102 and the shroud can be used. In one embodiment, the cup 102 is mounted to the underside of the shroud (eg, a plurality of screws pass up through the threaded holes 126 to lock the cup 102 to the shroud above the cup 102) . In another embodiment, the flange 124 can be disposed on the upper side of the shroud while the remainder of the cup 102 protrudes through the opening in the shroud.
杯形件102具有第一開口128以接納銷130。銷130被鎖固至護罩所附接至的結構(例如,用以固持電子元件或類似物的外殼之框架)。滑塊104亦包括銷開口132,該銷開口的尺寸經設定以接納銷130。當銷130位於銷開口132中時,滑塊104之移動使得整個閂鎖100相對於固定的銷130前後移動。The cup 102 has a first opening 128 to receive the pin 130. The pin 130 is locked to the structure to which the shield is attached (e.g., the frame of the housing for holding electronic components or the like). The slider 104 also includes a pin opening 132 that is sized to receive the pin 130. When the pin 130 is in the pin opening 132, the movement of the slider 104 causes the entire latch 100 to move back and forth relative to the fixed pin 130.
圖3A至圖3C示出了如何使用此機構將護罩300鎖固至殼體302。護罩300具有第一護罩邊緣304及與第一護罩邊緣304相對之第二護罩邊緣306。類似地,殼體302具有一開口,該開口形成於第一殼體邊緣308與第二殼體邊緣310之間,第二殼體邊緣310與第一殼體邊緣308相對地定位。閂鎖100係靠近第二護罩邊緣306固定至護罩300,而銷130係靠近第二殼體邊緣308固定至殼體302。閂鎖100可鎖固至護罩300的內表面或護罩300的外表面,而閂鎖之杯形件部分可作為護罩300之一部分而一體地形成。藉由將第一護罩邊緣304置於第一殼體邊緣308之後且將護罩300朝向第一殼體邊緣308 (圖3A)滑動,隨後將護罩300向下傾斜,以將第二護罩邊緣306定位成緊靠著第二殼體邊緣310 (圖3B)來安裝護罩300。此時,銷130會穿過杯形件之第一開口128且進入滑塊之銷開口132。接下來,將槓桿106移動至關閉位置,如此將滑塊104拉動至閂鎖位置。隨著滑塊104移動至閂鎖位置,銷開口132產生拉靠銷130的力。此力引起閂鎖100及護罩300沿著第二殼體邊緣310之方向滑動,如此將第二護罩邊緣306拉動至第二殼體邊緣310的下方(圖3C)。因此,閂鎖100被用於將護罩300鎖固至殼體302。移除護罩300係藉由按照相反次序進行前述步驟來完成。3A-3C illustrate how the mechanism 300 can be used to lock the shield 300 to the housing 302. The shroud 300 has a first shroud edge 304 and a second shroud edge 306 opposite the first shroud edge 304. Similarly, the housing 302 has an opening formed between the first housing edge 308 and the second housing edge 310, the second housing edge 310 being positioned opposite the first housing edge 308. The latch 100 is secured to the shroud 300 adjacent the second shroud edge 306, while the pin 130 is secured to the housing 302 proximate the second housing edge 308. The latch 100 can be locked to the inner surface of the shroud 300 or the outer surface of the shroud 300, while the cup portion of the latch can be integrally formed as part of the shroud 300. By placing the first shroud edge 304 behind the first housing edge 308 and sliding the shroud 300 toward the first housing edge 308 (Fig. 3A), the shroud 300 is then tilted downward to The cover edge 306 is positioned to abut the second housing edge 310 (Fig. 3B) to mount the shield 300. At this point, the pin 130 will pass through the first opening 128 of the cup and into the pin opening 132 of the slider. Next, the lever 106 is moved to the closed position, thus pulling the slider 104 to the latched position. As the slider 104 moves to the latched position, the pin opening 132 creates a force that pulls against the pin 130. This force causes the latch 100 and shroud 300 to slide in the direction of the second housing edge 310, thus pulling the second shroud edge 306 below the second housing edge 310 (Fig. 3C). Thus, the latch 100 is used to lock the shield 300 to the housing 302. Removal of the shield 300 is accomplished by performing the foregoing steps in reverse order.

儘管在本文中參考多個特定實施例來說明及描述本創作,但本創作不應限於所示之細節。相反,在申請專利範圍之範疇及等效範圍內且在不背離本創作的情況下,可做出各種細節上的修改。Although the present invention has been illustrated and described herein with reference to a particular embodiment, the present invention should not be limited to the details shown. On the contrary, various modifications may be made within the scope and equivalents of the scope of the patent application and without departing from the invention.
本創作人已發現,已知的護罩閂鎖機構有缺陷。詳言之,在圖1至圖2之閂鎖100中,槓桿106能夠樞轉而超出打開位置足夠遠,以至於槓桿106的上表面200接觸到杯形件102之邊緣202或接觸到鄰近杯形件102之邊緣202的護罩之一部分。此接觸可發生在圖2中由圓204標示出的區域內。此接觸會導致若干問題。舉例而言:接觸可能使槓桿106彎曲,可能刮掉保護漆、裝飾漆或表面塗層,可能使杯形件102彎曲,等。當閂鎖100經安裝至護罩之底側時(例如,凸緣124位於護罩之表面下),槓桿106亦可直接接觸護罩,此可能導致類似的刮擦及彎曲問題。本創作之多個實施例可解決此等及其他問題。The creator has discovered that the known shroud latching mechanism is defective. In particular, in the latch 100 of Figures 1-2, the lever 106 can be pivoted far enough beyond the open position that the upper surface 200 of the lever 106 contacts the edge 202 of the cup 102 or contacts an adjacent cup. A portion of the shroud of the edge 202 of the piece 102. This contact can occur in the area indicated by circle 204 in FIG. This contact can cause several problems. For example: contact may bend the lever 106, may scratch off the protective lacquer, decorative lacquer or surface coating, may bend the cup 102, and the like. When the latch 100 is mounted to the underside of the shroud (e.g., the flange 124 is located below the surface of the shroud), the lever 106 can also directly contact the shroud, which can cause similar scratching and bending problems. Various embodiments of the present invention address these and other issues.
圖4示出本創作之閂鎖400之一例示性實施例。閂鎖400具有杯形件402、滑塊404以及槓桿406。滑塊404係可移動地安裝至杯形件402,使得該滑塊能在閂鎖位置與解鎖位置之間移動。滑塊404係藉由被限制在杯形件402之底部表面與自杯形件側壁伸出的滑塊保持器408 (例如,銷、肋或類似物)之間而可移動地安裝至杯形件402,但可使用其他配置。槓桿406藉由一或多個槓桿銷410而以樞轉方式安裝至杯形件402,該一或多個槓桿銷裝配至槓桿406中之對應孔412及杯形件402中之對應孔414內。該等槓桿銷410形成一樞轉式連接,該樞轉式連接使槓桿406能夠在打開位置與關閉位置之間旋轉。FIG. 4 illustrates an illustrative embodiment of the present invention's latch 400. The latch 400 has a cup 402, a slider 404, and a lever 406. The slider 404 is movably mounted to the cup 402 such that the slider is movable between a latched position and an unlocked position. The slider 404 is movably mounted to the cup shape by being restrained between the bottom surface of the cup 402 and a slider holder 408 (e.g., pin, rib or the like) extending from the side wall of the cup. Item 402, but other configurations can be used. The lever 406 is pivotally mounted to the cup 402 by one or more lever pins 410 that fit into corresponding holes 412 in the lever 406 and corresponding holes 414 in the cup 402 . The lever pins 410 form a pivotal connection that enables the lever 406 to rotate between an open position and a closed position.
槓桿406藉由一或多個滑塊銷416而操作性地連接至滑塊404。滑塊銷416在偏離槓桿銷410之旋轉軸線的位置(例如,孔419)處固定至槓桿406,且滑塊銷416穿過滑塊404中之槽418。如此在槓桿406與滑塊404之間提供一驅動式連接,在該驅動式連接中,槓桿406在打開位置與關閉位置之間的旋轉引起滑塊404沿著杯形件402在解鎖位置與閂鎖位置之間移動。在其他實施例中可使用其他操作性連接(例如,凸輪表面或類似物)。The lever 406 is operatively coupled to the slider 404 by one or more slider pins 416. The slider pin 416 is secured to the lever 406 at a position offset from the axis of rotation of the lever pin 410 (eg, the aperture 419), and the slider pin 416 passes through the slot 418 in the slider 404. This provides a drive connection between the lever 406 and the slider 404, in which rotation of the lever 406 between the open position and the closed position causes the slider 404 to follow the cup 402 in the unlocked position and latch. Move between lock positions. Other operative connections (e.g., cam surfaces or the like) may be used in other embodiments.
杯形件402經結構設計為安裝至護罩、門或其他封閉結構。舉例而言,杯形件402可具有下表面420、自下表面420向上延伸之側壁422以及處於側壁422之頂部的凸緣424。(應理解,表示空間中之相對位置的術語,諸如「下」及「上」僅用來幫助解釋實施例,而非旨在要求實施例在空間中具有一特定定向)。凸緣424可具有一或多個螺孔426,以用於將杯形件402緊固至護罩,但可使用杯形件402與護罩之間的其他連接方式。在一個實施例中,杯形件402經安裝至護罩之底側(參見例如圖5A及圖5B)。在另一實施例中,凸緣424可安置在護罩的上側,而杯形件402之其餘部分穿過護罩中之開口突出。The cup 402 is structurally designed to be mounted to a shroud, door or other enclosed structure. For example, the cup 402 can have a lower surface 420, a sidewall 422 extending upwardly from the lower surface 420, and a flange 424 at the top of the sidewall 422. (It should be understood that terms referring to relative positions in space, such as "lower" and "upper" are used merely to help explain the embodiments, and are not intended to require that the embodiments have a particular orientation in the space. The flange 424 can have one or more threaded holes 426 for securing the cup 402 to the shroud, although other connections between the cup 402 and the shroud can be used. In one embodiment, the cup 402 is mounted to the underside of the shroud (see, for example, Figures 5A and 5B). In another embodiment, the flange 424 can be disposed on the upper side of the shroud while the remainder of the cup 402 protrudes through the opening in the shroud.
杯形件402具有第一開口428以接納一銷,諸如上文所描述之銷130。滑塊404亦包括銷開口432,該銷開口的尺寸經設定以接納該銷。閂鎖400的操作方式與上文所描述之閂鎖100基本上相同。亦即,在打開位置與關閉位置之間旋轉槓桿406使滑塊404在解鎖位置與閂鎖位置之間移動,且銷開口432在該銷上施加拉力,從而將護罩移動至殼體上的鎖固位置。將移動反向即使得滑塊推壓該銷,從而使護罩移動至一非鎖固位置,在該非鎖固位置中,該護罩能夠自殼體移除。The cup 402 has a first opening 428 to receive a pin, such as the pin 130 described above. The slider 404 also includes a pin opening 432 that is sized to receive the pin. The latch 400 operates in substantially the same manner as the latch 100 described above. That is, rotating the lever 406 between the open position and the closed position causes the slider 404 to move between the unlocked position and the latched position, and the pin opening 432 exerts a pulling force on the pin to move the shield onto the housing. Lock position. Reversing the movement causes the slider to push the pin, thereby moving the shield to an unlatched position in which the shield can be removed from the housing.
閂鎖400亦包括用以防止槓桿406轉過打開位置進而可能導致槓桿406、杯形件402或護罩損壞的一或多個特徵。舉例而言,在此實施例中,滑塊404包括第一行程止擋件434,該第一行程止擋件經結構設計為當槓桿406處於打開位置時接觸對應的第二行程止擋件436,且防止槓桿406移出打開位置之外。第一行程止擋件434位於自滑塊404的下側伸出之突出部438上。當組裝該等部件時,此突出部438位於穿過杯形件402的下表面420之第二杯形件開口440內。第二行程止擋件436位於第二杯形件開口440的一端,且較佳包含第二杯形件開口440之邊緣。The latch 400 also includes one or more features to prevent the lever 406 from rotating past the open position and possibly causing damage to the lever 406, the cup 402, or the shield. For example, in this embodiment, the slider 404 includes a first travel stop 434 that is configured to contact the corresponding second travel stop 436 when the lever 406 is in the open position. And prevents the lever 406 from moving out of the open position. The first stroke stop 434 is located on a projection 438 that projects from the underside of the slider 404. This projection 438 is located within the second cup opening 440 through the lower surface 420 of the cup 402 when the components are assembled. The second stroke stop 436 is located at one end of the second cup opening 440 and preferably includes the edge of the second cup opening 440.
如圖5A及圖5B中所示,槓桿406可自關閉位置(圖5A)移動至打開位置(圖5B)。在此移動期間,滑塊銷416壓住槽418的一側以使滑塊404自閂鎖位置(圖5A)移動至解鎖位置(圖5B)。當滑塊404到達解鎖位置時,第一行程止擋件434接觸第二行程止擋件436以防止滑塊404進一步移動及槓桿406進一步旋轉超過打開位置。因此,槓桿406不能接觸到杯形件402或鄰近的護罩500。As shown in Figures 5A and 5B, the lever 406 can be moved from the closed position (Figure 5A) to the open position (Figure 5B). During this movement, the slider pin 416 presses one side of the slot 418 to move the slider 404 from the latched position (Fig. 5A) to the unlocked position (Fig. 5B). When the slider 404 reaches the unlocked position, the first travel stop 434 contacts the second travel stop 436 to prevent further movement of the slider 404 and further rotation of the lever 406 beyond the open position. Thus, the lever 406 cannot contact the cup 402 or the adjacent shroud 500.
圖6為圖5B之一部分的細節圖,其展示了第一行程止擋件434如何接觸第二行程止擋件438。在此實例中,第一行程止擋件434包含突出部438之一凹口形部分,且第二行程止擋件436包含第二杯形件開口440之一邊緣。當滑塊404到達解鎖位置(且槓桿到達打開位置)時,第二行程止擋件436裝配在凹口形的第一行程止擋件434內。該凹口形狀幫助防止部件產生一反作用力,從而使突出部438向上偏離且脫離第二杯形件開口440,此幫助減小故障的可能性。此凹口形狀係有益的,但並非在所有實施例中都需要。舉例而言,在另一實施例中,第一行程止擋件434及第二行程止擋件438可包含兩個平行的表面,或兩個互補的表面(例如,凹面及配合該凹面之凸面)。6 is a detail view of a portion of FIG. 5B showing how the first stroke stop 434 contacts the second stroke stop 438. In this example, the first travel stop 434 includes a notched portion of the projection 438 and the second travel stop 436 includes one of the edges of the second cup opening 440. When the slider 404 reaches the unlocked position (and the lever reaches the open position), the second stroke stop 436 fits within the notched first travel stop 434. This notch shape helps prevent the component from creating a reaction, thereby causing the projection 438 to deflect upwardly and out of the second cup opening 440, which helps reduce the likelihood of failure. This notch shape is beneficial, but not required in all embodiments. For example, in another embodiment, the first travel stop 434 and the second travel stop 438 can comprise two parallel surfaces, or two complementary surfaces (eg, a concave surface and a convex surface that fits the concave surface) ).
圖7為當槓桿406處於打開位置時的閂鎖400之底部等角視圖。此視圖亦展示了第一行程止擋件434如何接觸第二行程止擋件436。Figure 7 is a bottom isometric view of the latch 400 when the lever 406 is in the open position. This view also shows how the first stroke stop 434 contacts the second stroke stop 436.
前述實施例有益於防止槓桿406之過度旋轉,且藉由將滑塊替換為具有第一行程止擋件434的滑塊而能夠方便地應用於已有的先前技術閂鎖中。然而,其他實施例可使用第一及第二行程止擋件434、436之不同配置。舉例而言,滑塊404可包括位於滑塊404之一個末端502處的第一行程止擋件,且杯形件402可包括位於杯形件402的內表面處的第二行程止擋件504。在此實施例中(類似於先前實施例),當滑塊到達解鎖位置且槓桿到達打開位置時,滑塊404之末端502將接觸第二行程止擋件504。滑塊末端502及第二行程止擋件504可包含平坦的平行表面,該等平坦的平行表面垂直於滑塊404之滑動方向延伸,因此該等表面之間的接觸不會產生可能使滑塊向上移動而脫離杯形件的力向量。參考本揭露內容,其他變型對於一般熟習此項技術者將顯而易見。The foregoing embodiments are useful for preventing excessive rotation of the lever 406 and can be conveniently applied to existing prior art latches by replacing the slider with a slider having a first travel stop 434. However, other embodiments may use different configurations of the first and second travel stops 434, 436. For example, the slider 404 can include a first travel stop at one end 502 of the slider 404, and the cup 402 can include a second travel stop 504 at the inner surface of the cup 402. . In this embodiment (similar to the previous embodiment), the end 502 of the slider 404 will contact the second travel stop 504 when the slider reaches the unlocked position and the lever reaches the open position. The slider end 502 and the second stroke stop 504 may comprise flat parallel surfaces that extend perpendicular to the sliding direction of the slider 404 so that contact between the surfaces does not create a possible slider The force vector that moves up and out of the cup. Other variations will be apparent to those of ordinary skill in the art in view of this disclosure.
