Description
本新型是有關於一種電連接器，特別是指一種用以夾持並電連接導線的電連接器。 The present invention relates to an electrical connector, and more particularly to an electrical connector for clamping and electrically connecting wires.
現有的以夾持方式形成電連接的連接器，例如台灣專利第I410009號公開一種用以電連接燈管的連接器，該連接器包括絕緣本體、導電端子及上蓋。其導電端子具有一對夾臂，並利用上蓋的兩干涉部擠壓夾臂以使夾臂將燈管夾持固定。然而，由於在燈管工作狀態時，夾臂接觸燈管且干涉部接觸夾臂，燈管產生的熱會經由夾臂直接傳導至干涉部，由於干涉部(絕緣殼體)為塑膠材料製成，長時間的高溫容易導致塑膠材料脆化。 A conventional connector for forming an electrical connection by a clamping method, for example, Taiwan Patent No. I410009 discloses a connector for electrically connecting a lamp tube, the connector comprising an insulative housing, a conductive terminal and an upper cover. The conductive terminal has a pair of clamping arms, and the clamping arms are pressed by the two interference portions of the upper cover to cause the clamping arms to clamp and fix the tube. However, since the clamp arm contacts the lamp arm and the interference portion contacts the clamp arm when the lamp is in the working state, the heat generated by the lamp tube is directly transmitted to the interference portion via the clamp arm, since the interference portion (insulating housing) is made of a plastic material. Long-term high temperature easily leads to embrittlement of plastic materials.
另外，例如中國大陸專利公開案第CN102237608A號公開一種用於電接線夾的操縱裝置，其可利用操縱帶有按壓臂的按鈕下壓而撐開接觸框的板式彈簧以取出或***電導線，而放開按鈕時板式彈簧可回復原位以夾持導線。由於該按鈕需要上下移動的行程，如此不利於電連接器低高度的設計及使用需求。 In addition, for example, the Chinese Patent Publication No. CN102237608A discloses an operating device for an electric terminal clip that can be used to remove or insert an electric wire by manipulating a leaf spring that presses a button with a pressing arm to open the contact frame. The plate spring can be returned to its original position to hold the wire when the button is released. Since the button needs to travel up and down, it is not conducive to the design and use requirements of the low height of the electrical connector.
因此，本新型之其中一目的，即在提供一種可以解決前述問題的電連接器。 Accordingly, it is an object of the present invention to provide an electrical connector that can solve the aforementioned problems.

The upper cover 3 is located in the upper opening 17 when the upper cover 3 is located in the first position, and the partial bottom surface 311 of the plate portion 31 abuts against the top surface 141 of the partition wall 14 to be supported by the partition wall 14 and the limiting protrusion 34 The top surface 141 can be blocked by the upper stop surface 1111 of the corresponding limiting recess 111, thereby limiting the upper cover 3 in the up and down direction. Moreover, one side of the adjacent wire inlet 16 of the plate portion 31 can be blocked by the first end wall 12 (in the first position), and the side of the back guide line 16 of the limiting protrusion 34 can be blocked by the side of the corresponding limiting recess 111. The face 1112 is stopped (located in the second position), whereby the upper cover 3 can be restricted in the wire insertion and removal direction A to be restricted from moving between the first position and the second position. The guide groove 142 of the top surface 141 of the partition wall 14 by the guide rib 33 of the upper cover 3 In cooperation, the upper cover 3 can be linearly slid along the wire insertion and removal direction A, thereby making the upper cover 3 slide smoothly between the first position and the second position.
使上蓋3可沿導線插拔方向A在兩個位置之間滑動的結構設計可以有多種方式，例如像抽屜式的結構在絕緣殼兩側壁形成滑槽並在上蓋兩側形成配合的滑軌，可以依據一般滑動結構設計變化調整，並不以本實施例為限，只要達到使上蓋3可沿導線插拔方向A在兩個位置之間移動的功能即可。當然，本實施例中的上蓋3亦可只有兩個限位凸部34而分別設於板部31兩側，則絕緣殼1的各側壁11即對應設置一個限位凹部111即可。再者，雖然本實施例是以適用電連接兩導線C的結構說明，但是亦可等效變化為適用電連接單一導線C。 The structural design that allows the upper cover 3 to slide between the two positions along the wire insertion and removal direction A can be variously. For example, the drawer-like structure forms a sliding groove on both side walls of the insulating case and forms a matching sliding rail on both sides of the upper cover. It can be adjusted according to the general sliding structure design, and is not limited to the embodiment, as long as the function of moving the upper cover 3 between the two positions along the wire insertion and removal direction A is achieved. Of course, the upper cover 3 in this embodiment may have only two limiting protrusions 34 and are respectively disposed on two sides of the plate portion 31. Therefore, each of the side walls 11 of the insulating case 1 may be correspondingly provided with a limiting recess 111. Furthermore, although the present embodiment is described in terms of a structure suitable for electrically connecting two wires C, it may be equivalently changed to be suitable for electrically connecting a single wire C.
參閱圖1、圖5至圖8，為方便說明凸塊32與端子2的作用關係，以下以單一凸塊32及與該凸塊32對應的端子2之作用關係進行說明。該上蓋3位於該第一位置時該凸塊32位於對應該對彈性臂23之間的位置但未與該對彈性臂23作用(見圖6)，該對彈性臂23的自由端部232在一可夾持導線C的夾持狀態。亦即，此時彈性臂23未受到凸塊32的作用力，使得該對彈性臂23的自由端部232傾向維持在相對靠近的位置，當導線C置於該對彈性臂23的自由端部232之間而使兩自由端部232互相朝相對遠離的方向彈性位移時，該對彈性臂23產生使自由端部232回復原位的彈性回復力而使自由端部232施力於導線C上將導線C夾持固定(見圖8)。 Referring to FIG. 1 and FIG. 5 to FIG. 8 , for convenience of explanation of the action relationship between the bump 32 and the terminal 2 , the following description will be given of the relationship between the single bump 32 and the terminal 2 corresponding to the bump 32 . When the upper cover 3 is in the first position, the protrusion 32 is located at a position corresponding to the elastic arm 23 but not to the pair of elastic arms 23 (see FIG. 6), and the free end 232 of the pair of elastic arms 23 is at A clamping state in which the wire C can be clamped. That is, at this time, the elastic arm 23 is not subjected to the force of the projection 32 such that the free end portion 232 of the pair of elastic arms 23 tends to maintain a relatively close position when the wire C is placed at the free end of the pair of elastic arms 23. When the two free end portions 232 are elastically displaced from each other in a direction away from each other, the pair of elastic arms 23 generate an elastic restoring force for returning the free end portion 232 to the original position, and the free end portion 232 is biased on the wire C. Hold the wire C in place (see Figure 8).
參閱圖9至圖13，在本實施例中，該上蓋3由該第一位置往該第二位置移動是朝遠離該導線入口16方向移動。該上蓋3位於第二位置時，該上蓋3部分移出該上開口17而超出該第二端壁13(見圖4)，而且該凸塊32將該對彈性臂23的自由端部232撐開而使該對彈性臂23的自由端部232在一解除夾持導線C的解除狀態(見圖11、13)。具體而言，當上蓋3由第一位置往第二位置移動的過程中，凸塊32的錐形前端會先抵於彈性臂23的導引部234的導引面2341(見圖3)並相對導引面2341移動而逐漸將兩彈性臂23的導引部234往外撐開，並由導引部234帶動整個彈性臂23使自由端部232亦被往外撐開而使兩自由端部232之間維持間隔一定距離，且兩自由端部232之間的距離大於導線C的線徑，使得導線C不受自由端部232夾持而能無障礙的通過兩自由端部232之間，如此可方便插拔導線C。亦即，若要***導線C時，將上蓋3移動至第二位置，藉由凸塊32將該對彈性臂23的自由端部232撐開而使兩自由端部232在解除狀態，可在***導線C時能夠達到零***力，待將導線C***至定位後，再將上蓋3移動至第一位置(見圖1)，移除凸塊32對彈性臂23的施力，即可使兩自由端部232將導線C夾持固定。由於***導線C時能夠達到零***力，本實施例特別適用於導線C為較軟的多芯線，如此能方便使用者將導線C插置定位。若已插置導線C而要拔出導線C時，同樣將上蓋3移動至第二位置而使兩自由端部232在解除狀態，即可輕鬆拔出導線C 。在本實施例中，上蓋3還具有設於頂面141的兩凹槽35，以方便使用者對上蓋3施力而容易推動上蓋3。 Referring to FIG. 9 to FIG. 13 , in the embodiment, the movement of the upper cover 3 from the first position to the second position is moving away from the wire inlet 16 . When the upper cover 3 is in the second position, the upper cover 3 partially moves out of the upper opening 17 beyond the second end wall 13 (see FIG. 4), and the projection 32 opens the free end 232 of the pair of elastic arms 23. The free end portion 232 of the pair of elastic arms 23 is released in a released state (see Figs. 11, 13). Specifically, during the movement of the upper cover 3 from the first position to the second position, the tapered front end of the projection 32 first abuts against the guiding surface 2341 of the guiding portion 234 of the elastic arm 23 (see FIG. 3). The guiding portion 234 of the two elastic arms 23 is gradually extended relative to the guiding surface 2341, and the entire elastic arm 23 is driven by the guiding portion 234 so that the free end portion 232 is also outwardly extended to make the two free ends 232 A distance is maintained between the two ends, and the distance between the two free ends 232 is greater than the wire diameter of the wire C, so that the wire C is not clamped by the free end 232 and can pass between the two free ends 232 without barriers. Easy to plug and unplug the wire C. That is, when the wire C is to be inserted, the upper cover 3 is moved to the second position, and the free end portion 232 of the pair of elastic arms 23 is opened by the projection 32 to release the two free ends 232. When the wire C is inserted, the zero insertion force can be achieved. After the wire C is inserted into the positioning, the upper cover 3 is moved to the first position (see FIG. 1), and the force applied to the elastic arm 23 by the protrusion 32 is removed. The two free ends 232 clamp the wire C. Since the zero insertion force can be achieved when the wire C is inserted, the embodiment is particularly suitable for the wire C to be a soft multi-core wire, so that the user can conveniently position the wire C. If the wire C is to be inserted and the wire C is to be pulled out, the upper cover 3 is also moved to the second position, and the two free ends 232 are released, so that the wire C can be easily pulled out. . In the present embodiment, the upper cover 3 further has two recesses 35 provided on the top surface 141 to facilitate the user to apply force to the upper cover 3 to easily push the upper cover 3.
由於上蓋3是沿導線插拔方向A移動而省去上下按壓的行程，可以降低整體電連接器100的高度。在本實施例中，上蓋3與絕緣殼1都是由塑膠材料製成，電連接器100插置導線C時，上蓋3的凸塊32不會直接接觸端子2，能夠避免導線C工作產生的熱能直接傳導至凸塊32導致凸塊32脆化而影響其功能。 Since the upper cover 3 is moved in the wire insertion/removal direction A to eliminate the stroke of the upper and lower pressing, the height of the entire electrical connector 100 can be lowered. In this embodiment, the upper cover 3 and the insulating case 1 are both made of a plastic material. When the electrical connector 100 is inserted with the wire C, the bump 32 of the upper cover 3 does not directly contact the terminal 2, and the operation of the wire C can be avoided. Direct conduction of thermal energy to the bumps 32 causes the bumps 32 to embrittle and affect their function.
綜上所述，藉由上蓋3可沿導線插拔方向A在第一位置及第二位置之間移動並連動凸塊32一起移動，以控制端子2的彈性臂23的自由端部232在夾持狀態或在解除狀態，可方便插拔導線C，並能達到零***力的效果。再者，上蓋3是沿導線插拔方向A移動，可以降低整體電連接器100的高度，而且上蓋3的凸塊32在導線C工作狀態不會直接接觸端子2，能夠避免凸塊32長期受熱脆化而影響其功能。 In summary, the upper cover 3 is movable between the first position and the second position along the wire insertion and removal direction A and moves together with the projection 32 to control the free end 232 of the elastic arm 23 of the terminal 2 in the clamp. When the state is held or released, the wire C can be easily inserted and removed, and the effect of zero insertion force can be achieved. Moreover, the upper cover 3 is moved along the wire insertion and removal direction A, and the height of the overall electrical connector 100 can be lowered, and the bump 32 of the upper cover 3 does not directly contact the terminal 2 in the working state of the wire C, and the long-term heating of the bump 32 can be avoided. Embrittlement affects its function.
