Description
Technical field：
The utility model is related to a kind of connector double-body bike contact pins.
Background technology：
In industries such as railway industry communications, need to use many equipment transmission control information etc., the connection meeting between equipment
Use signal or data connector.Signal or data connector one end connection cables, the other end can be connected to inside equipment, usually
It is pcb board, sometimes by wire jumper, sometimes connector is attached directly on pcb board.
The connection of the pcb board of general connector pin is realized by soldering, and signal or data connector equipment end are arrived
With the contact pin of cable end in order to ensure connection long-term reliability and plug number and surface uses craft of gilding, but gold-plated insert
Metallic atom transport phenomena can occur in long-term use for the tin plating connection of needle and pcb board, for the long-term reliability of product, one
As by the way of contact pin selective electroplating, i.e., with plug mating portion using gold-plated and with the coupling parts PCB using tin plating；But
Contact pin electroplating technology can be caused complicated in this way, homogeneity of product is inserted and cost increase.Therefore, it is necessory to be carried out to the prior art
It improves to solve the deficiency of the prior art.
Utility model content：
The utility model is to provide a kind of connector double-body bike in order to solve the above-mentioned problems of the prior art and insert
Needle.
Technical solution used by the utility model has：A kind of connector double-body bike contact pin, including preceding electric conductor is with after
Electric conductor, rear electric conductor are conductive internal before being plugged in；
It is equipped with first boss, second boss and third boss on the outer circle wall of the preceding electric conductor successively from left to right,
And the diameter of three boss becomes larger successively from left to right, and jack is equipped on the end face of third boss；
Electric conductor is equipped with plug division after described, and plug division is plugged in jack；On plug division be equipped with positive stop lug boss and
Several convex ribs, convex ribs are located at the left side of positive stop lug boss,
The diameter of the plug division is less than the diameter of jack, and the diameters of convex ribs is more than the diameter of jack, positive stop lug boss it is straight
Diameter is more than the diameter of convex ribs；
It is coated with gold or silver on the preceding electric conductor, tin is coated on rear electric conductor.
Further, the preceding electric conductor is column construction, and rear electric conductor is structure of right angle tyoe.
The utility model has the advantages that：In the utility model different platings is plated on preceding electric conductor and rear electric conductor
Layer realizes the function that different connections need, and good product consistency, quality is easy to control, at low cost.
Description of the drawings：
Fig. 1 is the utility model explosive view.
Fig. 2 is the utility model installation diagram.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 and Fig. 2, a kind of the utility model connector double-body bike contact pin, including preceding electric conductor 1 and rear electric conductor 2,
Before electric conductor 2 is plugged on afterwards in electric conductor 1.
Preceding electric conductor 1 is column construction, is equipped with first boss successively from left to right on the outer circle wall of preceding electric conductor 1
11, second boss 12 and third boss 13, the diameter of third boss 13 are more than the diameter of second boss 12, second boss 12 it is straight
Electric conductor 1 is preferably fixed in plastic casing before diameter enables more than 11 diameter of first boss.At the end of third boss 13
Face is equipped with jack 14.
Electric conductor 2 is structure of right angle tyoe afterwards, plug division 20 is equipped on rear electric conductor 2, plug division 20 is plugged in jack 14
It is interior.Positive stop lug boss 21 and several convex ribs 22 are equipped on plug division 20, convex ribs 22 are located at the left side of positive stop lug boss 21.Plug division 20
Diameter be less than the diameter of jack 14, the diameters of convex ribs 22 is more than the diameter of jack 14, and the diameter of positive stop lug boss 21 is more than convex ribs
22 diameter.It before electric conductor 2 is plugged on afterwards after electric conductor 1, is interference fitted between convex ribs 22 and jack 14, ensures that connection is reliable
Property.
It is coated with gold or silver on preceding electric conductor 1, tin is coated on rear electric conductor 2.
Preceding electric conductor 1 and rear electric conductor 2 can plate different coating to realize that the function of different connection needs, product are consistent
Property is good, and quality is easy to control, at low cost.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
