Description

Insulating boots for solderless terminals

本发明涉及不用钎料而通过机械压接连接到电路及其各引线的无焊剂端子所使用的一种绝缘护套的构造。The present invention relates to the construction of an insulating sheath for use in fluxless terminals connected to electrical circuits and their respective leads by mechanical crimping without solder.

图1(a)和(b)示出了传统的绝缘护套1覆盖着无焊剂端子2，端子2与引线3连接，引线3则基本上垂直于无焊剂端子的端子体延伸。从图中可以看到，绝缘护套1的后端由片11和片12组成，保护着引线3和引线3与无焊剂端子2之间的连接件4，所述上下片与相对覆盖着端子前端及其附近的护套本体的壁铰接着，片11和12的最尾部分合上时弯曲形成护套的后端壁。打开铰接着的片11和12就可以把无焊剂端子2和引线3插入护套中。无焊剂端子2和引线3插入就位之后，将片的弯曲自由端上形成的凸起17嵌入于另一片接合端上开设的孔18中就可以将护套合上。Figures 1(a) and (b) show a conventional insulating sheath 1 covering a solderless terminal 2 connected to a lead wire 3 extending substantially perpendicular to the terminal body of the solderless terminal. It can be seen from the figure that the rear end of the insulating sheath 1 is composed of a piece 11 and a piece 12, which protects the lead wire 3 and the connection piece 4 between the lead wire 3 and the solderless terminal 2, and the upper and lower pieces are oppositely covered with the terminal The walls of the sheath body at and near the front end are hinged, and the rearmost portions of the flaps 11 and 12 bend when closed to form the rear end wall of the sheath. Opening the hinged tabs 11 and 12 allows the insertion of the solderless terminal 2 and lead 3 into the sheath. After the solderless terminal 2 and the lead wire 3 are inserted in place, the sheath can be closed by inserting the protrusion 17 formed on the bent free end of the sheet into the hole 18 provided in the joint end of the other sheet.

然而，传统的绝缘护套如上所述有两个可开启的片11和12，因而无论其制造方法和其使用过程都相当复杂。However, the conventional insulating sheath has two openable pieces 11 and 12 as mentioned above, so both its manufacturing method and its use process are quite complicated.

此外，上下片合上时，其各自的自由弯曲端必须基本上彼此齐平。要满足这个要求，凸起17和孔18须从上下片的各自由端突出，如图1(b)中所示，从而又再次使其制造和使用过程进一步复杂化。Furthermore, when the upper and lower panels are closed, their respective free bending ends must be substantially flush with each other. To meet this requirement, the protrusions 17 and holes 18 have to protrude from the respective free ends of the upper and lower plates, as shown in Fig. 1(b), thereby further complicating its manufacture and use again.

本发明的目的是消除传统护套的上述缺点，办法是提供一种不仅易于打开和合上而且必要时便于将端子卸除的新型绝缘护套。The object of the present invention is to eliminate the above-mentioned disadvantages of conventional sheaths by providing a new type of insulating sheath which is not only easy to open and close but also facilitates the removal of the terminals if necessary.

为达到上述目的，本发明的那种保护着无焊剂端子及基本上垂直于端子体的引线的绝缘护套有一个不弯曲的护套片与护套体的壁铰接着，护套合上时形成护套的后端壁，在护套片的非铰接的自由端上设有一个钩，钩的自由端有一个弹性凸起，适宜从护套体内侧嵌入护套体对侧壁上的一个孔中。In order to achieve the above object, the insulating sheath protecting the flux-free terminal and the lead wire substantially perpendicular to the terminal body of the present invention has a non-bent sheath piece hinged with the wall of the sheath body, and when the sheath is closed, Forming the rear end wall of the sheath, a hook is provided on the non-hinged free end of the sheath sheet, and the free end of the hook has an elastic protrusion, which is suitable for inserting from the inner side of the sheath body into one of the opposite side walls of the sheath body. in the hole.

图1(a)和1(b)分别示出了传统的绝缘护套的平面图和横剖面侧视图，其中，引线和无焊剂端子半插入护套中。Figures 1(a) and 1(b) show a plan view and a cross-sectional side view, respectively, of a conventional insulating sheath with lead wires and solderless terminals half-inserted into the sheath.

图2示出了本发明绝缘护套的横剖面侧视图，图2(a)示出了引线和无焊剂端子半插入护套中的情况，图2(b)示出了引线和无焊剂端子已完全插入护套内的情况，图3(c)则示出了用针按压钩上的凸起以卸下无焊剂端子的情况。Fig. 2 shows the cross-sectional side view of the insulating sheath of the present invention, Fig. 2 (a) shows the situation that the lead wire and the solderless terminal are half inserted in the sheath, Fig. 2 (b) shows the lead wire and the solderless terminal has been fully inserted into the sheath, Figure 3(c) shows the case of pressing the protrusion on the hook with a needle to remove the flux-free terminal.

图3是本发明最佳实施例的横剖面侧视图。Figure 3 is a cross-sectional side view of a preferred embodiment of the present invention.

图4是本发明另一个最佳实施例的横剖面侧视图。Figure 4 is a cross-sectional side view of another preferred embodiment of the present invention.

图5和图6是本发明护套形状的平面图。5 and 6 are plan views of the shape of the sheath of the present invention.

图2(a)的侧视图表示一个无焊剂端子2，其端子体21在插入护套1的连接点处和引线3正交，从该图中明显看出，护套1的后端片13铰接地连接到护套的壁15上并且打开着以便连接到其上的无焊剂端子2和引线3插入。The side view of Fig. 2 (a) shows a solderless terminal 2, and its terminal body 21 is perpendicular to the lead wire 3 at the connection point inserted into the sheath 1. It is obvious from this figure that the rear end piece 13 of the sheath 1 It is hingedly connected to the wall 15 of the sheath and is open for insertion of the solderless terminal 2 and the lead 3 connected thereto.

端子2和引线3插入完毕之后，将后端片13通过将设在后端片13上的钩16的凸起17从铲状物内部嵌入壁14的孔18中而固定到护套的壁14，如图2(b)中所示，这样就将无焊剂端子2和引线3牢靠地装入绝缘护套1中。After the terminal 2 and the lead wire 3 have been inserted, the rear end piece 13 is fixed to the wall 14 of the sheath by inserting the protrusion 17 of the hook 16 provided on the rear end piece 13 into the hole 18 of the wall 14 from the inside of the shovel , as shown in FIG. 2(b), so that the solderless terminal 2 and the lead wire 3 are firmly packed into the insulating sheath 1.

需要将无焊剂端子2和引线3从绝缘护套1中取出时，可以用针5按压凸起17(如图2(C)中所示)，从而将后端片13从壁14上释放开。绝缘护套2的后端片13是由弹性塑料制成的，因而不难插入孔18中或从孔18中取出。When the flux-free terminal 2 and the lead wire 3 need to be taken out from the insulating sheath 1, the protrusion 17 can be pressed with the needle 5 (as shown in Fig. 2(C)), thereby releasing the rear end piece 13 from the wall 14 . The rear end piece 13 of the insulating sheath 2 is made of elastic plastic so that it is not difficult to insert or remove it from the hole 18 .

在进入孔18之前，凸起17向前滑动，与壁14的内表面接触，如图2(b)中所示。因此凸起17最好应使其形状形成得保证其能在壁14的内表面上平稳滑动，并能顺利地嵌入孔18中。Before entering the hole 18, the protrusion 17 slides forward, making contact with the inner surface of the wall 14, as shown in Fig. 2(b). Protrusion 17 is therefore preferably shaped such that it slides smoothly over the inner surface of wall 14 and fits smoothly into hole 18 .

图3示出了横截面的形状基本上呈三角形的凸起17，图4示出了横截面的形状由不同的弧形组合而成的凸起17。FIG. 3 shows a protrusion 17 whose cross-section is substantially triangular, and FIG. 4 shows a protrusion 17 whose cross-section is a combination of different arcs.

具有钩16和凸起17的后端片13的护套1可以制成各种形状。图5示出了一种L字形护套，其一部分21覆盖着引线3及其接头，其另一部分22覆盖着无焊剂端子2的接头端23，该两部分在平视图中彼此正交。图6示出了另一种护套，该护套的平面图基本上呈矩形。The sheath 1 of the rear end piece 13 with hooks 16 and protrusions 17 can be made in various shapes. Fig. 5 shows an L-shaped sheath, one part 21 covers the lead wire 3 and its joint, and the other part 22 covers the joint end 23 of the solderless terminal 2, these two parts are orthogonal to each other in plan view. Figure 6 shows another sheath which is substantially rectangular in plan view.

通常，要配备一个或两个凸起17和相应数目的孔18，但这个数目没有具体加以限制。Usually, one or two protrusions 17 and a corresponding number of holes 18 are provided, but this number is not specifically limited.

虽然一个凸起17和一个孔18形成的组合是简单的，并且如图2(C)中所示的那样仅按压一个凸起17就可以放开后端片13，但两个或以上的凸起17和孔18形成的组合能保证更牢靠的接合。Though the combination that a protrusion 17 and a hole 18 forms is simple, and as shown in Fig. 2 (C), only pressing a protrusion 17 just can release the rear end piece 13, but two or more protrusions The combination of protrusion 17 and hole 18 ensures a more secure joint.

在本发明的绝缘护套中，如上所示出的那样，只有后端片13，而不是如前述传统护套中那样有两个对置的套件，相对于护套的上壁或下壁打开和关闭。另外，钩16上的小凸起17不仅容易嵌入孔18，而且提供顺利的操作。In the insulating sheath of the present invention, as shown above, only the rear end piece 13, instead of two opposed sleeves as in the aforementioned conventional sheath, is open with respect to the upper or lower wall of the sheath and off. In addition, the small protrusion 17 on the hook 16 not only fits easily into the hole 18, but also provides a smooth operation.

如图2(a)，2(b)，2(c)，后端片13不难使其与壁14接合，具体作法是先使钩16与壁14的内表面接触，然后使钩16上的凸起17嵌入壁14的孔18中。需要将引线3和无焊剂端子从绝缘护套中取出时，只要用针5按压钩16上的凸起17即可轻易地将后端片13打开。As shown in Figure 2 (a), 2 (b), 2 (c), the rear end piece 13 is not difficult to make it engage with the wall 14. The specific method is to make the hook 16 contact with the inner surface of the wall 14, and then make the hook 16 contact with the inner surface of the wall 14. The protrusions 17 are embedded in the holes 18 of the wall 14. When the lead wire 3 and the flux-free terminal need to be taken out from the insulating sheath, the rear end piece 13 can be easily opened by pressing the protrusion 17 on the hook 16 with the needle 5 .

虽然设计简单，但本发明的绝缘护套在许多方面却比传统的护套优越。Although simple in design, the insulating jacket of the present invention is superior to conventional jackets in many respects.
