20輪部36a底側上之扁平表面38。具體言之，用於各凸輪終端 32A之各凸輪部80係包括一第一概呈扁平的表面8〇&且其對 應於如第6(a)圖所示之致動器的完全開啟位置。凸輪部包括 一第二扁平表面80b且其對應於如第3(甸及13圖所示之致動 為的關閉位置。第一及第二扁平表面8〇a及8〇b分別在凸於 12 200403889 口P的一尖銳角部8〇c相遇。較佳實施例中，第一及第二扁平 表面對於彼此概呈垂直，藉此使尖銳角部8〇c為凸輪部8〇的 一 90°角部。 現在描述致動器14的操作，具體言之，第6(a)圖顯示致 5動器14處於其可使扁平電路48以箭頭“C”方向自由地分別 插入連接器的開口 18内及凸輪終端32A的上與下接觸臂44 與46之間的一嘴部82内之開啟位置中。扁平電路係如第6(b) 圖所示同時地插入樞轉終端32B的上與下接觸臂68與7〇之 間的一嘴部84内。由於致動器處於其如第圖6(a)所示的開啟 10位置中，各凸輪部80的第一扁平表面8〇以系在各別凸輪終端 32A之上安裝臂36的凸輪部36a底部扁平地抵靠住扁平表面 38。易言之，凸輪部8〇在致動器14的開啟位置中係以扁平 表面對扁平表面的接合方式有效地接合凸輪終端32A。這界 定了一非常確實的致動器開啟位置且致動器不會搖擺或振 15 動離開此確實界定的位置。 現在，再度參照第3(a)圖，致動器14處於其關閉位置 中。在致動器的關閉位置中，致動器之凸輪部8〇的第二扁 平表面80b係與凸輪終端32A的扁平表面38呈齊平狀或穩固 地接合。就像致動器的開啟位置一樣，此扁平表面對扁平 20表面的接合方式係對於致動器的完全關閉位置提供了一種 非常確實的辨識方式。 藉由對於確實界定的致動器開啟位置及關閉位置之上 文描述及瞭解，第7至10圖顯示了致動器14在其第6(a)圖的 開啟位置與其第3(a)圖的關閉位置之間的多個順序性位 13 200403889 置。第7至10圖顯示，在致動器從其開啟位置移動至關閉位 置期間，凸輪部80的第一扁平表面8〇a係與凸輪終端32八上 的扁平表面38分開，且致動器與凸輪終端之間的唯一接合 作用係位於凸輪部的尖銳(9〇度）角部80c上。在致動器樞轉 5運動的全程係持續具有與凸輪部的尖銳角部之此種接合作 用，直到致動器抵達其對應於凸輪終端上的扁平表面邛與 凸輪終端的第二扁平表面8〇b驟然接合之關閉位置為止。易 吕之，當致動為沿尖銳角部平滑地樞轉然後在扁平表面接 合而經歷一限定的動作改變或停止時，係具有一種顯著、 10驟然且確實的改變。操作員將感應或感覺到一關於致動器 已經抵達其關閉位置之顯著的“喀嚓，，或觸覺指示。 第16圖顯示，致動器14包括側壁9〇且其具有一凹入的 閂鎖肩部92,凹入的閂鎖肩部92係接合閂鎖突架％(第^圖） 以將致動為固持在其關閉位置中。各側壁9〇亦包括一可供 15閂鎖突架76接合之停止限制肩部94。 最後，第H(a)及H(b)圖根據上述的本發明顯示一連接 器的另一貫施例10A且其包括一安裝在一殼體12上之致動 裔14，其中致動為包括凸輪部8〇及樞轉銷或軸部以。再度 如同第3(a)及3(b)圖清楚地顯示，凸輪終端32八的撓性接觸 20臂46比樞轉終端32B的撓性接觸臂70更長，因此接觸部46a 及70a在一扁平電路的插入方向中彼此偏置。同樣地，凸輪 終端32A的接觸部44a相對於樞轉終端328的接觸部68&呈偏 置狀。第H(a)及l7(b)圖中適用類似的編號，可看出凸輪終 端32A的接觸部46a係垂直地對準於樞轉終端32b的接觸部 14 200403889 7〇a，且凸輪終端32A的接觸部44a係垂直地對準於樞轉終 32B的接觸部68a。 、 可瞭解本發明可以其他特定形式實施，而不脫 明之精神與中心特徵。因此，目前的範例及實施例在各^ 5面均視為示範用而非限制性質，本發明不侷限於本文提供 的細節。 【圖式簡單說明】 第1圖為用於貫施本發明概念之一扁平電路連接器的 立體圖，其中致動器處於其關閉位置中； 10 第2圖為連接器的俯視平面圖；

connectors, and specifically today, 5 levels-used to terminate such as flat flexible circuits, pull printed circuits or other = Connector for flat cable for flat circuit. t Previous Background of the Invention A wide variety of electrical connectors have been designed to terminate flat slow wires or circuits such as flat, short-winding, flexible printed circuits, or the like. A typical connector for a flat circuit includes, for example, a dielectric case molded from a plastic material. The housing has an elongated opening or slot for receiving the _ end of the flat circuit. This is a flat circuit with a generally ordered, laterally spaced conductor exposed across the end. A plurality of terminals are installed in the housing and laterally separated along 15 slots, wherein the contact portions of the terminals can be joined as laterally separated conductors of a flat circuit. The actuator is often removably mounted on the housing in a first position where the flat circuit can be freely inserted into the slot, and an actuator can clamp the circuit in the housing and bias the circuit against Move between the second position of the contact portion of the terminal. 20 No. 18.2 () ®㈣—a flat circuit connector having the above characteristics and as disclosed in Japanese Patent Laid-Open No. 2000-48886. This connector includes a housing of an actuator 3G1 with a pivotable wire, and the actuator 301 is pivotably mounted on the housing on a pivot axis 302 (section Η Figure). To this end, the 'actuated 11301' can be pivotally moved between the open position shown in FIG. 2 (5) -5200403889 and a closed position shown in FIG. The figure shows that the actuator includes a smooth cam portion 303 and engages a support beam 305 with a terminal 304 having a contact arm 306. The actuator is pivoted from the open position to the closed position in a continuous and smooth motion. 5 Figures 21 and 22 show a flat circuit connector as disclosed in Japanese Patent No. 2580074. The connector includes a housing 400 in which a pivoting socket 401 is formed, and an actuator 402 having a pivoting shaft 4⑹ which can be located in the socket. To this end, the actuator is pivoted between its open and closed positions in a continuous and smooth motion. A terminal 404 is installed in the housing and includes a support beam 405 having a pivot support 405, wherein the pivot support 406 may be located in a pivot path 407 of the actuator to further Provides continuous and smooth pivoting of the actuator. When the actuator is pivoted in the direction of arrow 412 toward its closed position, a smooth pressing surface 408 located on the actuator biases the flat circuit into a flexible contact arm 411 of the terminal. 15 Figures 23 and 24 show a flat circuit connector as disclosed in Japanese Patent No. 2892945. This connector includes a housing 500 for mounting an actuator 501, wherein the actuator 501 has a pivot axis 502 and provides actuation to be continuous between one of its open and closed positions and Smooth pivoting effect. As shown in Figure 24, the actuator 501 includes an additional pivot axis 5020 and is engaged with an arched pivot support 501 on a support beam 505 of a terminal 506. In a continuous and smooth actuation in the direction of the arrow 507 toward its closed position, a smooth pressing portion 508 biases the flat circuit 509 upward against a contact arm 510 of the terminal. As shown by the aforementioned flat circuit connector of the prior art, the actuator 6 is generally moved from its open position to the closed 2 position in a continuous and smooth motion and biases the circuit with a smooth cam surface. Unfortunately, this operation did not provide any instructions when it was actuated ⑤ to reach a position where a good electrical connection has been made between the flat circuit and the connector terminal 1. Therefore, the operator cannot clearly recognize whether the flat circuit has been correctly or properly connected. The present invention provides a structural combination that solves this problem by providing an apparent "fee," or tactile indication, when an actuator is moved from its open position to a closed position, to inform the operator that a connection has been reached. C ^^ 明 内容】 10 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electrical connector for terminating a flat circuit and having a novel and improved tactile indication actuator. In a non-limiting embodiment of the present invention, the connector includes a connector The electrical housing and the dielectric housing have an opening for one end for receiving a flat electrical 15-way in a circuit insertion direction. A plurality of terminals are installed in a side-by-side array and spaced apart along the opening = sideways. On the housing. Move the actuator on the housing to move between an open position where the flat circuit can be inserted into the opening and a closed position where the flat circuit is biased against the terminal. Some terminals include pivoting Terminal and it has a tow 2 20 _ device for engaging the actuator to install the actuator to move between the open position and the closed position. Mountain tuning, X 3%, and cam end ^ Department The material engages the flat surface of the actuated ㈣ cam portion. At least the cam portion of the actuator includes a generally flat surface and its engaging projection: a flat surface at the end of 200403889 and defines the open position of the actuator. The cam portion includes a first Two generally flat surfaces and a flat surface that can engage a cam terminal to define the closed position of the actuator. The first and second approximate surface surfaces of the cam portion meet at a sharp angle, and when the actuator is opened from When the position is moved to the closed position 5, the sharp corners engage the flat surface of a cam terminal to create a snap action, thereby providing a tactile indication that the actuator has moved from its open position to the closed position. As disclosed herein, The pivoting device on the pivoting terminal includes a hook portion and a pivoting shaft portion for receiving the actuator. Therefore, the pivoting device can prevent 10 actuators in a direction approximately parallel to the circuit insertion direction and a pair of The circuit is inserted in a direction that is perpendicular to the offset movement. The cam mechanism of the cam terminal prevents the actuator from being perpendicular to the direction of the circuit. Directions are offset in opposite directions. According to a form of the present invention, each pivoting terminal system includes a pair of arms and defines a mouth between 15 for receiving the end points of the flat circuit. One of the arms is a A flexible contact arm for engaging a flat circuit, and a second arm having a pivoting device. According to another aspect of the present invention, each cam terminal system includes a pair of arms and defines a flat receiving circuit therebetween. The mouth of the end point. One of the 20 arms is a flexible contact arm for engaging the flat circuit, and the second arm has a flat surface for engaging the respective cam portion of the actuator.

One of the upper mounting arms 36 protrudes in front of the base and can engage the housing at the top or roof of the passageway. The upper mounting arm 36 terminates in a Λ stand or end 36a with a flat bottom surface 38.纟 Cam terminal 32A has-approximately ^ -shaped contact 10 40 and it is bent and connected to the terminal base by a spring located on the proximal end of the upper mounting material. U-shaped contact is defined-upper flexible contact arm 44 Let ’s take a look at the flexible contact arm 46 and define it in between—for pure—flat circuits 48 such as flat pull electrical t, pull printed circuit boards or flat electrical money wires, etc.-: 上 上 Flexible contact arm 44 and The lower flexible contact arms are respectively defined as 15 = and the circuit traces on the top surface and bottom surface 3 of the flat circuit by which they are joined.

The upper flexible contact arm 68 and the lower flexible contact arm 70 are separated from the opposite contacts ⑽ & and 7 so as to join the top surface of the flat material and the wire surface—the circuit traces. “', FIGS. 4 and 5 and FIG.! FIG., Each of the metal reinforcement fittings 16 has—a bottom foot portion 72 connected to the printed circuit board by appropriate mounting, for example, by soldering. Each fitting includes— an outer side wall 74 and It has a flexible joint flange% 'with a flash lock slot 闪 in this flexible joint flange 74a to flash lock the accessory to the dual body 12. A reinforced accessory is also shown in Figures 14 and 15, and can be It can be seen that the groove 7_material (Fig. 14) is bent inwardly as shown in Fig. 15-the flash lock protrusion 76. The mounting plate 78 protrudes approximately parallel to the flexible joint flange 7. 15 Before continuing to describe the function or action of the actuator 40 in Figures 6 to ⑺, refer to Figures 12 and 13, which show that the actuator 14 has a pressing surface 79 for engaging the flat circuit 48 and biasing the circuit. Presses against the contact portion 46a of the contact arm 46 of a cam terminal 32A. The actuator 14 also has a cam portion 2 and is operatively associated with each cam terminal 32A and thereby engages the bottom side of the convex portion 20 of the wheel portion 36a Upper flat surface 38. Specifically, each cam portion 80 for each cam terminal 32A includes a first profile The flat surface 80 & corresponds to the fully open position of the actuator as shown in Fig. 6 (a). The cam portion includes a second flat surface 80b and corresponds to as shown in Fig. 3 (Fig. 13 and Fig. 13). The actuated position shown is closed. The first and second flat surfaces 80a and 80b meet at a sharp corner 80c that protrudes from 12 200403889 port P. In a preferred embodiment, the first And the second flat surface are approximately perpendicular to each other, thereby making the sharp angle portion 80c a 90 ° angle portion of the cam portion 80. The operation of the actuator 14 will now be described, specifically, section 6 (a) The figure shows the actuator 14 in a mouth portion 82 which allows the flat circuit 48 to be freely inserted in the opening 18 of the connector in the direction of arrow "C" and the upper and lower contact arms 44 and 46 of the cam terminal 32A, respectively. Inside the open position. The flat circuit is simultaneously inserted into a mouth 84 between the upper and lower contact arms 68 and 70 of the pivot terminal 32B as shown in FIG. 6 (b). Since the actuator is in its position In the open 10 position shown in FIG. 6 (a), the first flat surface 80 of each cam portion 80 is tied to the projection of the mounting arm 36 above the respective cam terminal 32A. The bottom of the wheel portion 36a is flat against the flat surface 38. In other words, in the open position of the actuator 14, the cam portion 80 effectively engages the cam terminal 32A in a flat surface-to-flat surface engagement manner. This defines A very positive actuator open position and the actuator will not sway or vibrate away from this well-defined position. Now referring again to Figure 3 (a), the actuator 14 is in its closed position. In the closed position of the actuator, the second flat surface 80b of the cam portion 80 of the actuator is flush with or flatly engaged with the flat surface 38 of the cam terminal 32A. Just like the open position of the actuator, the engagement of this flat surface to the flat 20 surface provides a very reliable way to identify the fully closed position of the actuator. Based on the above description and understanding of the actuator's open and closed positions that are actually defined, Figures 7 to 10 show the open position of actuator 14 in Figure 6 (a) and Figure 3 (a) Multiple sequential bits between the closed position of 13 200403889. Figures 7 to 10 show that during the movement of the actuator from its open position to the closed position, the first flat surface 80a of the cam portion 80 is separated from the flat surface 38 on the cam terminal 32, and the actuator and The sole engagement between the cam ends is located on the sharp (90 °) corner 80c of the cam portion. Throughout the entire movement of the actuator 5 the system continues to have this engagement with the sharp corners of the cam until the actuator reaches its flat surface corresponding to the cam terminal 邛 and the second flat surface 8 of the cam terminal 〇b Suddenly close to the closed position. Yi Luzhi, when actuated to smoothly pivot along sharp corners and then meet on a flat surface to undergo a limited movement change or stop, there is a significant, sudden and sure change. The operator will sense or feel a significant "click, or tactile indication" that the actuator has reached its closed position. Figure 16 shows that the actuator 14 includes a side wall 90 and it has a recessed latch. Shoulder portion 92, recessed latch shoulder portion 92 engages the latching projection (Fig. ^) To hold the actuation in its closed position. Each side wall 90 also includes a 15 latching projection for each 76 engagement stop limit shoulder 94. Finally, Figures H (a) and H (b) show another embodiment 10A of a connector according to the invention described above and includes a mounting on a housing 12 Actuator 14, in which the actuation includes a cam portion 80 and a pivot pin or a shaft portion. As shown clearly in Figs. 3 (a) and 3 (b) again, the flexible contact of the cam terminal 32 and the arm 20 contacts 46 It is longer than the flexible contact arm 70 of the pivot terminal 32B, so the contact portions 46a and 70a are offset from each other in a flat circuit insertion direction. Similarly, the contact portion 44a of the cam terminal 32A contacts the pivot terminal 328 Part 68 & is offset. Similar numbers are applied to the figures H (a) and 17 (b), and it can be seen that the contact part 46a of the cam terminal 32A is Straightly aligned with the contact portion 14 of the pivot terminal 32b 14 200403889 70a, and the contact portion 44a of the cam terminal 32A is vertically aligned with the contact portion 68a of the pivot terminal 32B. It can be understood that the present invention may be in other specific forms Implementation without loosing the spirit and central characteristics. Therefore, the current examples and embodiments are considered exemplary and not restrictive in every aspect, and the present invention is not limited to the details provided herein.
