固持裝置在工業或日常生活等領域都很常用。比如電腦主機板上常要設置卡緣連接器，以組接擴充卡式模組，為增加卡式模組與它組接的穩固性，通常採用固持裝置。現有設計可參考中國大陸專利第〇〇 2 5 0 9 7 6號專利（如第九圖所示），它是於卡緣連接器上裝設有固持裝置，主要包括有一樞軸、一主體部，連接在主體部上下兩端的扣壓臂、頂出臂，及由扣壓臂向後延伸生成的扳動部。借扣壓臂卡扣在卡式模組的勾設部上將卡式模組固持。這種卡緣連接器有如下缺陷：該固持裝置容設於連接器絕緣本體内，扣壓臂大小及力量承受能力受到了限制，產生的扣壓力較小，組裝後卡式模組容易由於震動等原因而從卡緣連接器中脫落；另外，卡式模組和扣壓臂的接觸點位於樞軸軸心的内側，當勾設部有向外運動的趨勢時，將對扣壓臂施加一順時針方向的力臂，如凸塊和凸緣的配合力不夠大時’ 卡式模組將會脫離固持裝置，而使該卡式模組無法正常工作；再者，該固持裝置只有在打開狀態時，卡式模組才可以裝入，由此給組裝帶來了不便。因此有必要作出新的設計改變上述缺陷。【新型内容】本創作之主要目的，乃在於提供一種具有較佳固持效Holding devices are commonly used in industries such as industry or daily life. For example, card edge connectors are often set on computer motherboards to connect expansion card modules. In order to increase the stability of the card module and its connection, a holding device is usually used. For the existing design, please refer to the Chinese Patent No. 002 50 0 976 (as shown in the ninth figure). It is equipped with a retaining device on the card edge connector, which mainly includes a pivot and a main body. , The crimping arms, the ejecting arms connected to the upper and lower ends of the main body portion, and the triggering portion generated by the crimping arms extending backward. The depressing and pressing arm is buckled on the hooking part of the cassette module to hold the cassette module. This kind of card edge connector has the following defects: the holding device is accommodated in the connector's insulating body, the size and strength of the crimping arm are limited, the crimping pressure generated is small, and the card module is liable to vibration due to assembly, etc. Due to the card edge connector; in addition, the contact point of the card module and the crimping arm is located on the inner side of the pivot axis. When the hooking portion has a tendency to move outward, a clockwise will be applied to the crimping arm When the force of the force arm in the direction, such as the protrusion and the flange, is insufficient, the card module will be disengaged from the holding device, and the card module will not work properly. Furthermore, the holding device is only in the open state. , The cassette module can be installed, which brings inconvenience to assembly. Therefore, it is necessary to make a new design to change the above defects. [New content] The main purpose of this creation is to provide a better retention effect

For the purpose of insulation, make sure that the first and the holder are connected to the locust shaft connector bag, and the crimping arm group is included. The design of the connection to the tow shaft is to keep the insulation of the contact shaft of the object device in the insulation through the core to avoid the holding effect. The contact shaft is inherently buckled to the same holding fruit. Device card edge connector design. As a holding device, a slot is provided for the first object and the first object to hold the second object. The main body and the crimping arm should be fixed to the second object, and the axis of the shaft is located on the same vertical, including the outer edge of the pivot. The main body and the pivot and the outer side of the pivot are used as fixed arms and strips to erected the body and the pivot is provided with a pivot hole in the insulating body.

Creation instructions (3) The pivot hole 21 is provided, and a limiting hole 22 is provided on a side wall away from the end. The holding device 1 includes a one-piece main body portion 10, a trigger portion 15 extending backward from the main body portion 10, and a crimping arm 1 extending integrally from the main body portion 10 to the side 1. The ejection arm 1 3 , The pivot 11 and the projection 14. The holding arm 12 further includes a guide slope 120.

固持裝置1從絕緣本體1 一側邊***。為了保證固持裝置1可以順利安裝到卡緣連接器主體2上，樞軸1 1自由末端設有卡扣部1 1 2，該卡扣部1 1 2在本實施例中為中間開槽的圓臺形凸起，安裝時，該卡扣部1 1 2 穿過樞接孔2 1樞接固定於絕緣本體2上。固持裝置1此時即可以樞軸11為轉軸轉動。頂出臂1 3也***到絕緣本體2上的限位孔2 2内。限位元孔2 2限制了固持裝置1從閉合狀態到打開狀態所能夠轉動的幅度。The holding device 1 is inserted from one side of the insulating body 1. In order to ensure that the holding device 1 can be smoothly installed on the card edge connector body 2, the free end of the pivot shaft 11 is provided with a buckling portion 1 1 2. The buckling portion 1 1 2 in this embodiment is a circle with a slot in the middle. The table-shaped protrusion is pivotally fixed on the insulating body 2 through the pivot hole 21 when being installed. The holding device 1 can be rotated at this time by the pivot shaft 11. The ejection arm 13 is also inserted into the limiting hole 22 of the insulating body 2. The limiting element hole 22 limits the range that the holding device 1 can rotate from the closed state to the open state.

因為該扣壓臂、頂出臂、樞軸均系從主體部一側一體延伸而出，因此橫閂在卡式模組勾設部上方的扣壓臂長度不受絕緣本體的限制，能夠對勾設部產生較大的扣壓力，再加上樞軸也是橫穿樞接孔而不易退出，故該種固持裝置能有效避免卡式模組因震動等情況而脫落；另外，因為扣壓臂系橫閂在卡式模組勾設部上方，故可扣在勾設部的較中央位置，也能有效避免卡式模組因震動等情況而脫落，明顯提高卡緣連接器的工作可靠性。參閱第三圖、第四圖、第五圖、第六圖，卡式模組3 從絕緣本體2上方垂直向下***，勾設部3 1首先觸碰到扣壓臂1 2上的導引面1 2 0 ，有受力分析可知，扣壓臂1 2會受Because the withholding arm, ejecting arm, and pivot shaft all extend from one side of the main body, the length of the withholding arm that is horizontally latched over the hooking part of the card module is not limited by the insulating body, and can be hooked. A large buckling pressure is generated on the part, and the pivot shaft also crosses the pivot hole and is not easy to withdraw. Therefore, this kind of holding device can effectively prevent the card module from falling off due to vibration and other conditions; In addition, because the buckling arm is a horizontal latch It is above the hooking part of the card type module, so it can be buckled in the relatively central position of the hooking part. It can also effectively prevent the card type module from falling off due to vibration and other conditions, which obviously improves the working reliability of the card edge connector. Referring to the third, fourth, fifth, and sixth figures, the card module 3 is inserted vertically downward from the upper part of the insulating body 2. The hooking portion 31 first touches the guide surface on the holding arm 12 1 2 0, according to the force analysis, it can be seen that the holding arm 1 2 will be subject to

勾設部3 1施加的水平方向向左的力，進而帶動整個固持裝置1以樞軸為中心逆時針方向轉動（如第四圖箭頭所示），當固持裝置轉到扣壓臂1 2上扣壓頂點1 2 1 和卡式模組3 上勾設部3 1左側面3 1 0 剛接觸時，卡式模組3即可***到卡緣連接器主體2内，然後勾設部3 1按壓頂出臂1 3，帶動固持裝置1順時針方向轉動直到處於閉合狀態。整個過程操作者只需手持卡式模組3***到卡緣連接器主體2而免去了首先將固持裝置1扳動到打開狀態的預動作，因此組裝非常方便。並且，固持裝置1處於閉合狀態時，扣壓臂 1 2和卡式模組3上的勾設部3 1的接觸點1 2 2 位於樞軸1 1軸心1 1 3 的外側，由力矩分析可知，當卡式模組***時，固持裝置1有逆時針方向轉動的趨勢，更加有利於固持裝置逆時針旋轉而達到打開狀態，便於卡式模組的組裝。如第五圖所示，固持裝置1處於閉合狀態時，扣壓臂 1 2和卡式模組3上的勾設部3 1的接觸點1 2 2 位於樞軸1 1軸心1 1 3 水平方向的左側，由力矩分析可知，卡式模組3若有脫離絕緣本體2的趨勢時其勾設部3 1會在接觸點1 2 2 上對扣壓臂1 2施加一個垂直向上的力F 1 ，而因為該力作用點The horizontally leftward force applied by the hooking part 31 drives the entire holding device 1 to rotate counterclockwise around the pivot axis (as shown by the arrow in the fourth figure). When the holding device turns to the holding arm 12 for holding Vertex 1 2 1 and the upper part 3 of the card-type module 3 1 Left side 3 1 0 When the contact is made, the card-type module 3 can be inserted into the main body 2 of the card edge, and then the upper part 3 1 presses the top The out arm 1 3 drives the holding device 1 to rotate clockwise until it is in a closed state. In the whole process, the operator only needs to hold the card-type module 3 and insert it into the card edge connector main body 2 without the pre-action of first pulling the holding device 1 to the open state, so the assembly is very convenient. In addition, when the holding device 1 is in a closed state, the contact point 1 2 of the holding arm 12 and the hooking portion 31 on the cassette module 3 is located outside the pivot 1 1 and the axis 1 1 3. When the card module is inserted, the holding device 1 has a tendency to rotate counterclockwise, which is more conducive to the counterclockwise rotation of the holding device to an open state, which facilitates the assembly of the card module. As shown in the fifth figure, when the holding device 1 is in a closed state, the contact point 1 of the holding arm 12 and the hooking portion 3 1 on the cassette module 3 1 2 2 is located at the pivot 1 1 axis 1 1 3 horizontally According to the torque analysis, if the card module 3 has a tendency to detach from the insulating body 2, its hooking portion 31 will apply a vertical upward force F 1 on the contact point 1 2 2, And because the force acts

位於樞軸1 1軸心1 1 3 的外側，所以固持裝置1有順時針方向（如第五圖箭頭所示）轉動的趨勢而反扣起來，將卡式模組3卡死，避免了固持裝置的順時針旋轉，從而提高了卡緣連接器的工作可靠性。當然，接觸點與軸心也可在同一條豎直線上，同樣能避免固持裝置順時針旋轉而提高卡緣連接器的工作可靠性。Located on the outside of the pivot 1 1 axis 1 1 3, so the holding device 1 has a tendency to turn clockwise (as shown by the arrow in the fifth figure) and buckle back, locking the card module 3 to avoid holding The device rotates clockwise, thereby improving the working reliability of the card edge connector. Of course, the contact point and the axis can also be on the same vertical line, which can also avoid the clockwise rotation of the holding device and improve the working reliability of the card edge connector.
