Description
本創作係與電器用品有關，特別關於一種按壓式彈出插頭之延長線插座。 This creation is related to electrical appliances, in particular to an extension cord socket for a push-type pop-up plug.
人類文明進步至今，電的應用已廣泛的使用於人們的日常生活中。一般使用電為其動力來源的產品，除了內部配置有電池的產品外，均需要將該產品連接電源，方能使其正常運作。因此，插頭與插座的需求是與日俱增的。 Since the progress of human civilization, the application of electricity has been widely used in people's daily lives. Products that generally use electricity as their power source, in addition to products with internal batteries, need to be connected to the power supply to enable them to operate normally. Therefore, the demand for plugs and sockets is increasing.
為了維持良好的電性連接狀態，插座內部的電極簧片會緊緊的夾住***的插頭。因此，使用者在***或是拔除插頭時，均需要施以相當的力量方能完成。就創作人的觀察，在將插頭***插座時，因施力的需要，使用者大多會握住插頭的頭部，進行***動作。但是在拔除插作時，大多的使用者會握住電線，並非是握住插頭的頭部。此現象固然有使用者貪圖方便的問題，但是也包含了握住插頭頭部不好施力的問題。因此，在多次握住電線拔除插頭後，很容易造成電線與插頭電性連接的失效，使得插頭損壞。 In order to maintain a good electrical connection, the electrode springs inside the socket clamp the inserted plug tightly. Therefore, the user needs to apply considerable force when inserting or removing the plug. As far as the creator's observation is concerned, when the plug is inserted into the socket, the user often holds the head of the plug for the insertion action due to the force application. However, when the plug is removed, most users will hold the wire, not the head of the plug. This phenomenon is of course a problem that the user is greedy, but it also includes the problem of holding the plug head and applying force. Therefore, after the wire is pulled and removed a plurality of times, it is easy to cause the electrical connection between the wire and the plug to fail, and the plug is damaged.
本創作之主要創作目的在於提供一種按壓式彈出插頭之延 長線插座，其可提供一種新的移除插頭的操作模式，以減少插頭損壞的機會。 The main purpose of this creation is to provide a push-type pop-up plug extension Long-line sockets provide a new mode of operation for removing the plug to reduce the chance of plug damage.

The inner wall of the tubular member 32 is provided with a plurality of brake ribs 34 which extend in a direction parallel to the axial direction of the tubular member 32.
該制動件12裝設於該基座10中，具有一轉動元件36以及一固定元件38。請參閱第2圖所示，該轉動元件36具有一呈柱狀的主體，其外側面設有若干凸塊40環繞該主體，每一凸塊40之頂側具有二制動斜面42，而相鄰之二凸塊40之間具有一通道44。該轉動元件36的底端具有一凹槽，供該彈性件14的另一端***。該固定元件38同樣具有一呈柱狀的主體，其頂端具有一連接部46，外側面接近底端處設有若干凸塊48環繞該主體，每一凸塊48之底側具有一滑動斜面50以及一揚升斜面52，而相鄰之二凸塊48之間具有一通道54。該等滑動斜面50與該等制動斜42面具有相同之傾斜方向與相同之斜率。該等揚升斜面52朝向與該等滑動斜面50相反之方向傾斜，其一端分別連接該等滑動斜面50。該等揚升斜面52的長度大於該等滑動斜面50。另外，該基座10之制動肋34的一端具有一斜面56，具有與該等制動斜面42相同之傾斜方向與相同之斜率。 The brake member 12 is mounted in the base 10 and has a rotating member 36 and a fixing member 38. Referring to FIG. 2, the rotating member 36 has a cylindrical body, and a plurality of protrusions 40 surround the main body on the outer side thereof, and the top side of each of the bumps 40 has two braking slopes 42 adjacent to each other. There is a channel 44 between the two bumps 40. The bottom end of the rotating member 36 has a recess for the other end of the elastic member 14 to be inserted. The fixing member 38 also has a column-shaped main body having a connecting portion 46 at the top end thereof. The outer side surface is provided with a plurality of protrusions 48 around the bottom end, and a bottom side of each of the protrusions 48 has a sliding slope 50. And a rising ramp 52, and a channel 54 between the adjacent two bumps 48. The sliding ramps 50 have the same tilt direction and the same slope as the brake ramps 42. The ascending ramps 52 are inclined in a direction opposite to the sliding ramps 50, and one end thereof is connected to the sliding ramps 50, respectively. The length of the ascending ramp 52 is greater than the sliding ramps 50. In addition, one end of the brake rib 34 of the base 10 has a slope 56 having the same inclination direction and the same slope as the brake slopes 42.
該轉動元件36的頂端則***該固定元件38的底端，並可相對於該固定元件38自由轉動，且該轉動元件36的制動斜面42接觸於該固定元件38的滑動斜面50。該轉動元件36與該固定元件38均***該基座10的管元件32中，且該固定元件38的連接部46穿出該基座10的穿孔30。在此要特別說明的是，該轉動元件36與該固定元件38以該等凸塊40,48為外環面的直徑，小於該管元件32的內徑，但大於以該等制動肋34為環面的直徑；而該 以該等制動肋34為環面的直徑大於該轉動元件36與該固定元件38之主體的外徑。 The top end of the rotating member 36 is inserted into the bottom end of the fixing member 38 and is freely rotatable relative to the fixing member 38, and the braking ramp 42 of the rotating member 36 is in contact with the sliding ramp 50 of the fixing member 38. The rotating element 36 and the fixing element 38 are both inserted into the tube element 32 of the base 10, and the connecting portion 46 of the fixing element 38 passes through the through hole 30 of the base 10. It should be particularly noted that the rotating element 36 and the fixing element 38 have the diameter of the outer ring surface with the protrusions 40, 48, which is smaller than the inner diameter of the tube element 32, but larger than the braking ribs 34. The diameter of the torus; The diameter of the toroidal ribs 34 is larger than the outer diameter of the rotating member 36 and the body of the fixing member 38.
該面板16上具有三插孔58，與該基座10之頂壁26上之三插孔28對應。該面板16的底側面設有一結合部60，連接於該固定元件38的連接部46。 The panel 16 has three receptacles 58 corresponding to the three receptacles 28 on the top wall 26 of the base 10. The bottom side of the panel 16 is provided with a joint 60 that is connected to the connecting portion 46 of the fixing member 38.
藉由以上結構，該面板16可於一下壓位置(請參閱第3圖與第5圖)以及一彈起位置(請參閱第4圖與第6圖)之間移動。當該面板16位於該下壓位置時，該面板位於該基座10的凹室中，但仍與該頂壁26保持一預定距離，當該面板16位於該彈起位置時，該面板16離開該凹室一預定距離，此時，該轉動元件36轉動至該等制動斜面42對應於該固定元件38的通道54，該等制動肋34位於該固定元件38的通道54中，由於該彈性件14的作用，該轉動元件36的制動斜面42抵靠於該等制動肋34底端的斜面56。當該面板位於該彈起位置時，該轉動元件36轉動至該轉動元件36的通道44對應於該固定元件38的通道54，該等制動肋34位於該固定元件38與該轉動元件36的通道中44,54。每當該面板16被按壓時，由於該等制動斜面42、滑動斜面50、揚升斜面52的配合，再輔以該彈性件14的作用，均會造成該轉動元件36轉動一角度，使得該面板16在該下壓位置與該彈起位置間循環轉換。 With the above structure, the panel 16 can be moved between a depression position (see FIGS. 3 and 5) and a pop-up position (see FIGS. 4 and 6). When the panel 16 is in the depressed position, the panel is located in the recess of the base 10, but remains at a predetermined distance from the top wall 26, and the panel 16 leaves when the panel 16 is in the pop-up position. The recess is at a predetermined distance, at which time the rotating element 36 is rotated to the braking ramp 42 corresponding to the passage 54 of the securing member 38, the brake ribs 34 being located in the passage 54 of the securing member 38 due to the resilient member Acting 14, the braking ramp 42 of the rotating member 36 abuts against the ramp 56 at the bottom end of the brake ribs 34. When the panel is in the pop-up position, the rotating member 36 is rotated to the passage 44 of the rotating member 36 corresponding to the passage 54 of the fixing member 38, and the brake ribs 34 are located in the passage of the fixing member 38 and the rotating member 36. 44,54. Whenever the panel 16 is pressed, due to the cooperation of the braking ramp 42, the sliding ramp 50, and the lifting ramp 52, supplemented by the action of the elastic member 14, the rotating member 36 is rotated by an angle so that the rotating member 36 is rotated. The panel 16 is cyclically shifted between the depressed position and the pop-up position.
當欲將一插頭(圖未示)***本創作之插座時，該插頭的電極端子的***該面板16以及該頂壁26的插孔58,28而進入該基座10內部。下壓該插頭的力量，使該轉動元件36轉動，造成該面板16轉換至該下壓位置，並且使該插頭的電極端子***位於該基座10內的電極夾片中，以達成電性連接。當使用者再次下壓該插頭時，會造成該轉動元件36的再次轉動，該 彈性件14的彈力會將該面板16移動至該彈起位置，並使得該插頭的電極端子脫離該等電極夾片。由於該插頭的電極端子不再受該等電極夾片的夾持，因此使用者可很輕易地拔除該插頭。 When a plug (not shown) is to be inserted into the socket of the present invention, the electrode terminal of the plug is inserted into the panel 16 and the receptacles 58, 28 of the top wall 26 into the interior of the base 10. The force of the plug is pressed to rotate the rotating member 36, causing the panel 16 to switch to the depressed position, and the electrode terminal of the plug is inserted into the electrode clip located in the base 10 to achieve electrical connection. . When the user presses the plug again, the rotation of the rotating member 36 is caused again. The spring force of the resilient member 14 moves the panel 16 to the pop-up position and causes the electrode terminals of the plug to disengage from the electrode clips. Since the electrode terminals of the plug are no longer clamped by the electrode clips, the plug can be easily removed by the user.
根據本創作所提供的插座結構，使用者的施力方式，無論是***或是拔除插頭，均是下壓插頭，因此，就施力的便利性，使用者均會握住插頭進行操作，以避免拉電線造成插頭損壞的問題。其次，該彈性元件的彈力可輔助該插頭的電極端子脫離該等電極夾片，使拔除插頭的動作更為輕易。 According to the socket structure provided by the creation, the user's force application method, whether inserting or removing the plug, is a push-down plug, so that the user can hold the plug to operate with the convenience of the force application, Avoid the problem of plug damage caused by pulling the wires. Secondly, the elastic force of the elastic member can assist the electrode terminal of the plug to be detached from the electrode clips, so that the action of removing the plug is easier.
