Description

Electrical connection terminal {ELECTRICAL CONNECTION TERMINAL}

The present invention relates to the technical field of connectors, and in particular, to electrical connection terminals having advantages such as material reduction and high flatness.

Conventional connectors include, for example, wire-to-board (WTB) connectors and international standard (ISO) connectors. For these, reference may be made to FIG. 1, which is a structural diagram illustrating a conventional connector. In Fig. 1, the connector has a rubber wick 2, an aperture 4, a case 6, a fixing member 8, and a terminal 14. One end of the terminal 14 is formed on the circuit board side (not shown) as an SMT pin. Here, the terminal 14 is formed into a terminal shape as shown in FIG. 1 by employing a double bending method. However, since the terminal 14 is made of a conductive metal material, it itself has a characteristic of having elasticity, so that it is very difficult to control the flatness of the SMT pin in the bending process, and the terminal 14 is, for example, solder It becomes easy to cause problems, such as poor wetting. Therefore, the problem that conductivity is bad or that it cannot be challenged is caused.

Further, besides the possibility that the flatness may be deteriorated due to the above-mentioned two-fold bending method, a drawback of waste of material still remains. 2A and 2B, which are schematic structural diagrams explaining the conventional terminal 30 after bending and before bending, may be referred to. In FIG. 2A, the shape of a conventional terminal after being bent twice is shown, and the terminal 30 has a contact end 34 and a bent end 36, and the terminal 30 of FIG. 2A Before being formed into a shape, the terminal 30 is finally formed through, for example, cutting of the terminal to a predetermined length, thinning of the terminal, cutting of the band member 32, attachment to the rubber core 2, and two 90 degree bends. A terminal 14 as shown in FIG. 1 can be formed. As shown in FIGS. 2A and 2B, in order to form the terminal 30, a relatively long three-dimensional plate material provided for several bends and required to be cut into a terminal 30 having a band member 32 If it is not (not shown), it is clearly understood that the non-curved band member 32, the contact end 34, and the bent end 36 cannot be formed. Therefore, in FIGS. 2A and 2B, a three-dimensional plate material having a relatively large volume is required to be cut into the terminal 30.

In addition, reference is made to FIG. 3, which is a structural diagram illustrating a conventional terminal, for a means for solving the flatness defect of SMT. In FIG. 3, a terminal group 40 having a band member 42 and a terminal 44 is manufactured by directly cutting a three-dimensional plate material, and the manufacturing process in which this is employed is the aforementioned terminal group 40 formed by a punching method. ), the terminal 44 of this method does not need to undergo bending, and since the SMT pin can be formed directly, it becomes possible to effectively improve the production capacity. However, there is still a risk of problems in this method, and in order to form many terminals at the same time in the manufacturing process, unless the gap d is enlarged, individual terminals 44 cannot be distinguished. will result in wastage.

In view of this, the present invention proposes an electrical connection terminal capable of solving problems caused by conventional terminals.

The first object of the present invention is to provide an electrical connection terminal that can obtain the effect of material reduction in the manufacturing process.

The second object of the present invention is to effectively reduce the gap between the terminals in the above-mentioned electrical connection terminals by a specific method such as arranging the terminals at an angle, for example, to obtain the effect of material saving. It is to provide what is there.

The third object of the present invention is to form an independent terminal by directly separating the terminal from the band member in the case where bending processing in the subsequent process is unnecessary in the above-described electrical connection terminal, and furthermore, it is also independently inserted into the hole of the rubber wick. It is to provide something that can be inserted and installed.

The fourth object of the present invention is to form a connector by directly applying to a rubber core by the rotation of a band member in the case where the bending process in the subsequent process is unnecessary in the above-mentioned electrical connection terminal, so that its high degree of flatness can be realized. is in providing

A fifth object of the present invention is to improve the production capacity by enabling a plurality of terminals to be attached at once by the rotation of the band member in the above-described electrical connection terminals, when the flatness is not affected. is in providing

In order to achieve the above object and other objects, the present invention provides a band member and an electrical connection terminal having a plurality of terminals. Each of the plurality of terminals includes a plurality of inflection points and has a gap between the plurality of terminals. Among them, the plurality of terminals are arranged in a manner inclined at a certain angle. The range of angles is between 30 and 55 degrees. Among them, the plurality of terminals are located on the same plane as the band member or located close to the same plane as the first step.

In addition, in order to achieve the above and other objects, the present invention provides an electrical connection terminal applied to an assembly member having a rubber wick, a plurality of apertures, a case, and a fixing member. The electrical connection terminal has a plurality of terminals. The plurality of terminals are respectively inserted into the plurality of openings, each of the plurality of terminals includes a plurality of inflection points, and has a gap between the plurality of terminals.

In FIG. 4A , the electrical connection terminal 10 includes a band member 12 and a plurality of terminals 14 .

Each of the plurality of terminals 14 includes a first bending point 1422 and a second bending point 1424 , respectively. When the first inflection point 1422 and the second inflection point 1424 make the shape of the plurality of terminals 14 appear in a Z-shape, as another embodiment, the number of inflection points is more than two The shape of each plurality of terminals 14 is serrated. In addition, an angle interposed by the first inflection point 1422 and the second inflection point 1424 is formed, and the range of the angle is between 45 degrees and 90 degrees, or between 90 degrees and 135 degrees. . A gap (d) is provided between the plurality of terminals 14 .

It should be noted that the plurality of terminals 14 are arranged in such a way that they are inclined at a certain angle, and the range of the angle is between 30 degrees and 55 degrees, for example. Here, an angle of 45 degrees is taken as an example, that is, the plurality of terminals 14 are arranged in such a way as to be inclined at 45 degrees, and there is also a gap d between the plurality of terminals 14, which is clearly described above. The point is that it is smaller than the gap D shown in FIG. 3 . Here, the gap d has the same change tendency, so that the plurality of terminals 14 are arranged in parallel. As another embodiment, the plurality of terminals 14 may be arranged non-parallel (non-parallel).

Referring together with Figure 4b, it is shown that the plurality of terminals 14 are located on the same plane as the band member 12, or located close to the same plane. Here, we define it as the first step. In this embodiment, the step of installing the plurality of terminals 14 and the band member 12 in a structure located on (or adjacent to) the same plane is defined as the first step.

This angular difference still belongs to the category of the utility model in which the band member 12 and the plurality of terminals 14 referred to in the present invention are close to the same plane.

Referring to FIG. 5, which is a schematic diagram explaining the separation of the terminal of FIG. 4A from the band member. 5, after the first step, the band member 12 and each of the plurality of terminals 14 are separated so that the band member 12 is not connected to any of the plurality of terminals 14. Here, the separation of the band member 12 and all the terminals 14 will be described as an example, and in other embodiments, one or a plurality of terminals 14 may be individually removed from the band member 12 as needed. can also be removed. Each of the plurality of terminals 14 after separation may be independently inserted into the hole 4 of the rubber core 2 as shown in FIG. The two terminals 14 may be installed by being inserted into the opening 4 at the same time using a synchronous interleaving method.

Therefore, after the independent terminal 14 is inserted into the opening 4 of the rubber wick 2 and installed, the band member 12 cannot be seen, but the terminal 14 adopts the manufacturing process method of this method, It is possible to form a high-quality terminal 14 with the advantages of saving material and realizing a high degree of flatness.
