Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings, and the pin of the present invention is illustrated by taking the round hole pin with the smallest size and the more common application as an example.

The utility model provides a small and exquisite pluggable circuit patch cord, contains wire 3 and round hole contact pin, and wherein the round hole contact pin has public head end 1 and female head end 2 simultaneously, and the different contact pins are connected respectively to the single-ended electricity connection contact pin of wire 3 or the both ends of wire 3, and electric connection mode can be welding, bonding or crimping, and the electric connection point is the 2 outer walls of female head end of contact pin.

Because of the skin effect of the current, the multi-strand wire adopted by the utility model has stronger conductive capability than a single-strand wire with the same section, and the hardness of the wire is moderate; simultaneously, each strand of electrically conductive heart yearn of stranded wire is silvered pure copper wire, makes the utility model discloses a wire pressure drop is littleer, so belong to more excellent wire jumper, more be applicable to precision circuit and precision measurement instrument. And the single-strand wire has a simpler structure and lower cost than the multi-strand wire with the same section.

The utility model discloses use the polytetrafluoroethylene that hardly does not receive any chemical reagent to corrode as the insulating layer, greatly limit has solved the problem that the wire was corroded and the emergence accident in experiment, industrial debugging or other fields.

The utility model discloses a round hole contact pin of small dimension is as the link, has solved the big problem of wire jumper link size in the market furthest. The utility model discloses a round hole contact pin surface gild or tin-plating, strengthened round hole contact pin corrosion resisting property, and then guaranteed current transmission efficiency. As shown in figure 2, the four-claw conical spring plate with extremely strong elasticity is arranged in the spring plate, so that the stability of electric connection is ensured.

This round hole contact pin has public head end and female head end simultaneously, can directly insert corresponding port or the female head end of inserting the round hole contact pin with corresponding plug in actual operation, uses as the tee bend type wire jumper, has improved the integrated level of circuit.

The connection mode shown in fig. 4 realizes the function that the same port is directly connected with other two branches, the two ports can be inserted and pulled randomly, and the complicated procedure of welding a wire again or reconnecting the wire is avoided under the condition of single-wire connection.

Aiming at the lead, the lead with different lengths can be selected as required in practical application so as to solve the problem that the length of the jumper is insufficient or the length is redundant. In a word, three-way type wire jumper has solved the multiple not enough of wire jumper in the existing market.

Example 1

As shown in fig. 1, in the drawing, a small and exquisite pluggable circuit patch cord includes stranded wire and round hole contact pin, and the mode of electricity connection is adopted at the both ends of wire to combine together with the round hole contact pin, and wherein the electricity connection mode can be welding, bonding or crimping, and the electricity connection point is located the female first outer wall of contact pin. Because of the skin effect of the current, the multi-strand wire is adopted, so that the multi-strand wire with the same section has stronger electric conduction capability than a single-strand wire.

Example 2

The multi-strand wire of example 1 may be replaced by a single strand wire, and the two ends of the single strand wire are connected to the round pins by electrical connection as described above. The jumper wire of this type has a simple structure and a low price although the conducting capacity is not as good as that of the jumper wire in embodiment 1.

Example 3

As shown in fig. 4 or 5, the small and exquisite pluggable circuit patch cord comprises a wire and a round hole pin, the jumper wire of the type is only combined with the round hole pin at one end of the wire in the above electric connection mode, the jumper wire of the type is flexible, and the jumper wire can be applied to the condition that one end is fixed and the other end is used as a plug end.

The foregoing shows and describes the general principles of the present invention, with its principal features and advantages, and further, various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
