Description of the Invention: [Technical Field] The present invention relates to a terminal for an electric wire having a terminal box made of an insulating material and a contact assembly having a plurality of rows arranged in a row Adjacent to the terminal contacts, and the ends of the insulated electrical leads can be inserted in parallel with each other on the same side of the terminal box. Contact assemblies of such terminals are typically constructed of a piece of spring steel sheet and a current busbar that is shared by all of the terminal contacts and made of a material that is electrically conductive. On the piece of spring steel, a plurality of reeds having the same number of contacts as the spring tongue are cut out (or stamped out), and the root of the tongue is connected to the upper edge of the magazine steel piece. The free end of the spring tongue extends toward the lower edge of the spring steel sheet and is aligned with the current busbar. The tabs and the current busbar respectively form a terminal contact for use as an electronic and mechanical clamp point for the electrical conductor to which the terminal is inserted. [Prior Art] The original type of this type of terminal has been known since 1973 (German Patent Case DE 23 17 _ C3). The basic structure of the terminal block has a contact plate made of a steel material having a shape of a block (thickness) and being substantially rigid and electrically conductive. The contact plate is the spring steel piece of the carrier of the contact assembly, the cutting spring tongue, and the j is on the contact plate. On the block-shaped board, each terminal contact is provided with a ^-shaped opening. The electric wires that need to be clamped first pass through the window-shaped opening, and then use the free ends of the individual spring tongues and the lower edge or lower edge of the contact plate to sway. If the word = connection, the original type of the line terminal, has been modified several times as time progresses. For example, in the German patent application DE 44 45 603 A1, the isi. 717, which is an example of the original flat connection 1 can be changed into a folded angle form, which cannot be changed by the modification, is S: 5 1355780 The plate or modified to (4) is a block (thick) carrier of the contact assembly, the window is provided with a window-shaped opening, so that the end of the inserted wire is clamped to the terminal contact, allowing The clamped electrical conductors pass through first. The above types of terminals are still widely used in building interiors, but even successful products must meet market requirements. These requirements (as in the past) are more costly to manufacture. It is cheaper (ie, it is reduced), and the energy is made smaller (ie, the height of the structure is lowered). In order to meet the requirements of the first item to reduce the cost, a follow-up type is developed from the original type described above. A current busbar with a much smaller area, replacing the bulky (thick) contact plate/contact body originally made of relatively expensive copper material, and the shape of the current busbar is across the spring tongue Current busbar frame or current sink Bars. This type of frame or strip-shaped current busbars, due to the use of expensive copper, has a corresponding minimum wire area limit. These current busbars (relative to the contact components) are not The function of the carrier is further provided by the lower edge of the spring steel sheet. The window opening is here provided on the spring steel sheet (see German Patent No. DE 203 03 537 U1). According to the terminal type of the aforementioned German patent DE 203 03 537 U1. In this type, the end of the insulated electric wire is passed through a window-shaped opening which is formed by cutting the spring tongue on the spring steel sheet. Then, the electric wire can be clamped electronically and mechanically to the end of the spring tongue and the corresponding end of the frame or strip-type current bus bar. The task of the invention is to create such types of terminals, which also meet the aforementioned second market requirement, that is, to meet the structural height reduction requirements.

"The guidelines of the present invention contain an innovative idea. Professionals still regard it as a habit and necessary 'is the upper edge of the spring steel sheet and the tongue root of the spring tongue. It is necessary to practice the electric wire as far as possible so that the length of the spring tongue has enough spring lines,' The spring tongue positioning angle of the New (4) can output a relatively constant wire tension on the pure electric wire. And the invention is allowed to take another path. This criterion combines the maximum flattening angle and the shorter reed length, resulting in a significant structural height reduction for this innovative and terminal according to the invention, and this approach (more precisely explained below) does not It has an adverse effect on the clamping force of the wire and/or the pulling force of the wire. By implementing the principles of the present invention, a new type of terminal having the smallest structure can be obtained, as shown in the detailed drawings. The contact assembly of the figure terminal is structurally high in height and does not protrude beyond the outer contour of the electrical conductor, which depends on the outer diameter of the insulating sheath of the conductor. This type of minimum size terminal (such as the clamp terminal of the junction box) that is related to the height of the structure has not been achieved so far. In practice, this type of terminal has obvious advantages. More terminals of this type can be installed in each space unit. Even in narrow wiring boxes or general machine tool junction boxes, many of these innovative and highly structurally narrow terminals can be used well. Although the structural height of the new terminal is reduced, sufficient wire clamping force and wire tension are maintained, because according to the second paragraph of the patent application, the spring tongue has a shape pre-formed by processing technology. The root of the tongue of the spring tongue starts at the first corner (ie, the corner of the root), so that the spring tongue avoids the electric wire clamped, and then the second corner (ie, the corner of the fold) ), fold 7 1355780 to the electric wire of the sweet center. The two pre-forms (root corners and turn-back corners) are processed by the cold-casting technique of the spring material, so that even if the spring tongues have a flattened positioning angle on the electric wires of the clip, A high spring force can still be achieved. According to the third paragraph of the patent application scope, the end of the tongue of the tongue is tied with the electric wire of the sweet clip as follows, that is, the edge of the tip of the tongue and the oblique angle of the electric wire. Hey. To ensure that the wire has enough tension. α It must be pointed out here that the aforementioned features of the present invention can be applied not only to a single row of wires, but also to two rows of terminals, where the terminal contacts are designed in two rows parallel to each other, such as The double-row six-wire cable shown in German Patent No. DE 54 523 C2. Double-row terminal blocks—in general, the mirrors of the single-row terminals are symmetrical in two rows. , Li Yili's new practice is about the technical solution, that is, how to flatten the current busbar with a very thin surface thickness, and fix it with the lower edge of the spring steel sheet without additional fixing aids. (such as point, catch, or punch). According to the solution of the fourth application of the patent application scope, the current busbar of the lower edge of the spring steel sheet is fixed, and a part of the window-shaped opening will be stopped at this point, and the reverse line is inserted into the universal fold back to form a The reverse guide wire insertion direction is opened, and the other side is the metal-shaped V-shaped receiving slot. a current busbar that is inserted into the V-shaped receiving slot and has a flat surface and a thin wall thickness, and the length of the spring tongue is measured as such, that is, it must be fastened to the terminal contact that is not used or closed. The window of the spring steel sheet is opened π, and it is placed against the lower edge of the electric dragon row and fixed. This type of flat, frame-shaped current busbar (or bar-shaped current busbar as required) is fixed to the lower edge of, for example, a spring steel sheet, and is added to the new terminal by an automatic processing machine. When jade, there is also a significant H Wei Wei flow row can be inserted into the slot without springs, without the need for other auxiliary 1355780 =. At this point, the spring tongue will be pressed back from the rest position and then the current trr will be pre-fixed in the v-shaped receiving slot _. The material to be pre-fixed is made of automatic processing machine 'automatically mounted on the whole of the insulated wire. The current busbar must be fixed in the v-shaped receiving slot in advance so that the two pieces are assembled. The shooting program can be easily loaded and sorted according to the recommendation of the fifth item of the patent application side. The electric charm is discharged in the V-shaped sensing slot, and is provided for each terminal. The current busbar negative portion is a protruding support bump), and the heads are inserted into the receiving slot at the current busbar _' to buckle the window-shaped openings which are respectively disposed on the spring steel sheet, against the wire insertion direction The part that is folded back. A strip-shaped current busbar with a flat cross section and a relatively thin wall thickness is selected to help reduce the height of the structure. Such a current busbar has a flat (no gap) lower surface that can be fixed in the v-shaped receiving slot in such a manner that it is placed obliquely against the direction of wire insertion, and the current busbar is placed The lower surface can provide a sliding slope for the electrical wires inserted into the terminal contacts (see the scope of claim 6). [Embodiment] FIG. 1 is a cross section of the terminal box 10, which has a The panel 11' on the front side of the wire insertion direction is provided with wire insertion holes 12, 13 and 14 so that it can insert a total of three electric wires 15 in the forward and parallel directions (see Fig. 3).

It consists of a spring steel sheet 16 (see Figure 6) and a current bus bar 17 (see Figure 5). The current busbar is made of a well-conducting steel. On the spring steel sheet 16, three springs 1355780 spring tongues 21 equal in number to the terminal contacts are cut, so that three window openings are formed on the spring steel sheets. The size of the window opening is substantially equal to the size of the reed which is cut and its end portion 25, which is best seen in Figure 6. The de-insulated end 18 of the electrical conductor must pass through the window opening before being individually clamped by the associated terminal contacts in electronic and mechanical sweetness. The electric conductor is inserted into the terminal together with a length of insulating sheath 19. The three-wire type terminal of the figure has three terminal contacts. Each of the terminal contacts is constructed between the free end 20 of the spring tongue 21 and the current busbar 17. The best drawing is a side view of the installed contact assembly shown in Figure 4. The spring tongue 21 is cut from the ridge steel sheet 16 in the following manner (see Fig. 6), i.e., the tongue root portion 22 is fixedly coupled to the upper edge 23 of the so-called spring steel sheet. The free end of the spring tongue extends toward the lower edge 24 of the spring steel sheet. The lower edge 24' of the spring steel sheet is folded back together with the window-shaped opening portion 25 stopped there, so as to be folded back against the wire insertion direction, so that a reverse wire insertion direction is formed on the spring steel sheet, and the other side is the most The v-shaped receiving slot 26 of the wide metal connection. The current busbar 17 shown in Figure 5 is mounted in the v-shaped receiving slot 26. The structure of the current busbar 17 is a flat strip-plate current busbar having a flat section. It spans all three terminal connections. The wall thickness of the structural phase is thin, and only U is slightly thicker than the material of the spring steel sheet - some (refer to Figure 4). The current ^ is provided with three current busbar heads 27 protruding from the side, which When the head is inserted into the V-shaped receiving slot 26, the portion that extends into the window-shaped opening and folded back in the direction in which the wire u is inserted is a flat and relatively thin current bus bar. , placed in the v-shaped receiving notch 26, that is, its smooth lower surface, as a sliding slope of the inserted electrical wire.

The tongue end 20 of the spring tongue forms an angle with the clamped electrical conductor, so that the edge of the sweet clip at the end of the tongue is at an oblique angle to the electrical conductor. . This small angle pulls up the wire pull. The root bending angle 28 pre-formed by the processing technique and the pre-formed folding corner 29' cause the spring tongue to exert a considerable clamping force on the clamped electrical conductor. The wire clamping force is limited by the spacer 3〇 on the spring steel sheet (see Fig. 6), which is formed by the support plate 31 on both sides and adjacent to each spring tongue, and when the tongue is played When the film is opened, it can independently apply auxiliary elastic force. In order to reinforce the strength of the auxiliary elastic force expected on the support plate, each of the rotating plates has a pre-formed elastic corner 32 (see Fig. 4 and Fig. 6). The aforementioned contact assembly requires only terminals in the assembled state. There is little space in the insulating material box. Figure 2 and Figure - show that not only the m3 of the spring steel piece and the tongue root 22' of the spring tongue can be placed next to the de-insulating end 18 of the (four) central electrical conductor 15. The lower edge 24 of the bomb and the current busbar 17 where the position is fixed can also be used. The result shows that on the spring steel sheet, the window formed by the cutting (or punching) of the spring tongue is mainly opened. The direction of extension, the main axis of the electrical conductor with (4) clips, and the flattened angle of the flat (4). This way, the contact component "structural dimension (which is also the same as the structural height of the entire terminal) can be significantly reduced. Fig. and Fig. 2 can clearly observe the structural height reduction of the terminal. 11 1355780 Spring steel sheet upper edge 23 (including the spring tongue 21 that grows here), and the spring steel sheet lower edge 24 (including the stationary current) Bus 17), will not stand out In addition to the outer contour, a profile of the outer diameter of the wire insulation cover 19 extending parallel to the axis, the cover is the largest cross section of the wire and can be clamped in the illustrated terminal.
