Abstract

PURPOSE:To facilitate coupling of multiple poles connector by applying a low friction conductive material as a coating on the electrically contacting part of a terminal. CONSTITUTION:A conductive low friction material 5 is applied as a coating on both surfaces of a planar electrical contacting part 3 of a male terminal 1 from a chamfer part on the tip to the middle part. Meanwhile, a low friction material 9 is applied as a coating on the top part 7 and its vicinity of an elastic contacting part 6 of a female terminal 2 and a projecting electrically contacting part 8, facing to the elastic conducting part 6. The coupling among multiple poles connectors can be performed easily with hand fingers and the burden on workers can be relieved accordingly.

Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention relates to a low insertion force terminal that aims to reduce the insertion force when connecting terminals to each other. [0002] [0016] In addition, the female terminal 26 has an inclined surface 31 on the distal end side of the elastic electrical contact section 29, that is, on the distal end side excluding the apex 30 which is the contact point of the elastic electrical contact section 29, and A similar non-conductive low-friction material 34 is coated on the tip end, that is, the inclined surface 33 of the corner portion of the convex electrical contact portion 32 facing the contact portion 29 . [0017] As the low-friction material 28.34, for example, Teflon resin is used, and in that case, as shown in FIG. By baking Teflon resin 36 on the front and back surfaces of the tab 35 at the location corresponding to the position of the low-friction material coating 28 described above, or by applying a similar treatment to the tip of the tab 27 after punching, it is possible to efficiently production becomes possible. [0018] FIG. 6 shows a state in which the male terminal 25 is inserted into the female terminal 26. When the male terminal 25 is inserted, the low-friction material coating 28 at the distal end comes into sliding contact with the coating 34 at the distal end of the electrical connection section 29. Since it is inserted smoothly between the electrical contact portion 32 and the electrical contact portion 32, the initial insertion force is reduced. As the male terminal 25 is inserted, both terminals 25, 2
．． The six electrical contact portions 27, 30, and 32 come into contact with each other to enable electrical connection. [0019] FIG. 7 shows the above-mentioned low insertion force terminal 2526 (indicated by the solid line A) and the conventional terminal (14.21 in FIG. 8, shown by the broken line), with the horizontal axis representing the insertion stroke and the vertical axis representing the insertion force. 2, the resistance during the insertion stroke also decreases as the initial insertion force decreases. This is thought to be due to the reduction in initial galling and the effect of initial familiarization. [00201

[Effects of the Invention] As described above, according to the present invention, multi-pole connectors can be easily connected with each other using hands and fingers, thereby improving the joining work efficiency and reducing the burden on the operator. On the other hand, it is also possible to increase the number of terminals compared to the conventional case to increase the connection capacity. FIG. 8 is a perspective view showing a conventional example.
