Description

connection terminal

technical field

The invention relates to a connecting terminal, in particular to a connecting terminal capable of improving the reliability of a contact point.

Background technique

Press, as shown in Fig. 1 and Fig. 2A, most of the known connectors W1 are equipped with single-terminal connection terminals W2, and the single-terminal connection terminals W2 are easily warped and deformed due to external force, resulting in poor contact. .

As shown in Figures 2A and 2B, in order to improve the poor contact situation in the future, the single-terminal connection terminal W2 will be changed to a double-terminal connection terminal W3, and the double-terminal connection terminal W3 will include a first contact part W31 and a second The contact portion W32 is expected to allow one of the first contact portion W31 or the second contact portion W32 to still maintain a normal contact.

However, the fact is not so ideal, because once the two-terminal connection terminal W3 suffers from external destructive force, both the first contact part W31 and the second contact part W32 will suffer almost the same destructive force, and as shown in FIG. 3, the first Both the contact portion W31 and the second contact portion W32 have almost the same normal force (solid line and dotted line on the vertical axis) during the same force-bearing period (horizontal axis), so the first contact portion W31 and the second contact portion W31 The degree of deformation generated by the second contact portion W32 is also almost the same, so none of the above methods can effectively improve the contact reliability of the terminal.

Therefore, the inventor of the present invention is aware of the above-mentioned problems, and Naite devoted himself to research and combined with the application of theories, and finally proposed an invention with reasonable design and effective improvement of the above-mentioned defects.

Contents of the invention

The main purpose of the present invention is to provide a connecting terminal with improved contact reliability, so as to effectively improve the problem of contact reliability of known connecting terminals.

In order to achieve the above purpose, the present invention provides a connection terminal for improving the reliability of the contact point. The connection terminal includes a terminal base, and at least extends from the terminal base to include: a first contact unit, and the first contact unit includes a A first contact arm and a first contact end; and a second contact unit, the second contact unit includes a second contact arm and a second contact end, wherein the first contact unit and the second contact The units are parallel to each other and spaced apart from each other by a gap, and the first contact unit also has a protrusion extending from the first contact arm.

To sum up, the present invention can effectively change the positive force of the first contact unit and the second contact unit through the technical means of the protruding part, so when subjected to an external destructive force, the generated deformation will not It is almost the same, so it is more effective to reserve the terminals that are still in normal contact, so as to effectively improve the reliability of contact.

detailed description

[first embodiment]

Please refer to Fig. 4, Fig. 5A and Fig. 6, the present invention provides a connection terminal 10 that improves the reliability of the contact point for use with a connector 1, but the type of connector 1 is not limited, so as long as the connection The device 1 has the connecting terminal 10 used to improve the reliability of the contact point of the present invention, and all should belong to the protection category of the present invention.

The connection terminal 10 includes a terminal base 11 , and at least extends from the terminal base 11 to include: a first contact unit 12 and a second contact unit 13 .

The first contact unit 12 includes a first contact arm 121 and a first contact end portion 122, and the second contact unit 13 includes a second contact arm 131 and a second contact end portion 132, wherein preferably, the first contact unit 12 and the second contact unit 13 can be parallel to each other and separated by a gap 14 , and the first contact unit 12 also has a protruding portion 123 extending from the first contact arm 121 .

Preferably, the protruding portion 123 is a protruding portion 123 extending obliquely relative to the first contact arm 121, the intersection of the protruding portion 123 and the first contact arm 121 is a first intersection point 124, and the protruding portion 123 also Connected to the second contact arm 131 , a second intersection point 133 is now formed. In more detail, the protruding portion 123 may form an angle with the first contact arm 121 when extending outward from the first contact arm 121, but may not be perpendicular to each other, so that when the protruding portion 123 is further connected with the second contact arm 131, The distance from the first contact end 122 to the first intersection 124 will be different from the distance from the second contact end 132 to the second intersection 133. Please refer to FIG. 5A and FIG. The relationship leads to the fact that the first contact unit 12 and the second contact unit 13 have different positive forces (vertical axis), which can effectively promote the reliability of the terminal contact point, and at the same time, the protrusion 123 further divides the gap 14 into first The gap 141 and the second gap 142 .

In addition, please refer to FIG. 5B , which discloses another modification relative to the embodiment in FIG. 5A . The protruding portion 123 extending obliquely can further extend toward the direction of the terminal base 11 to expand and cover the entire first The gap 141 is connected to the terminal base 11 , so that the first contact unit 12 and the second contact unit 13 have different positive forces, so as to improve the reliability of the contact point of the terminal.
