Contact pin, however, the unreasonable structural design of the needle stand of existing connector, needle stand and wiring board are in mutual timing, contact pin and line
Road plate is easy to shake, and is not easy to the welding of contact pin and wiring board, and there is also structure is complicated, performance is insecure scarce for the connector
It falls into.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of structure it is simple, it is stable and reliable for performance,
Connect reliable bar connector.
To achieve the above object, the utility model uses a kind of bar connector, including needle stand, multiple settings are in needle stand
Contact pin, terminal base, the multiple terminal plates for being arranged in terminal base and being matched with each contact pin, one end of the contact pin has
The weld part being exposed at outside needle stand has the arc holding section to fasten with wiring board, the contact pin on the tail portion of the weld part
The other end have plug division, the terminal plate far from contact pin one end have pressure contact portion, the terminal plate is close to contact pin
One end there is grafting framework, elastic contact chip is provided in the grafting framework, one end of elastic contact chip has arc
Contact portion, is formed with holding chamber between the arc-shaped contact part and the inner wall of grafting framework, the plug division of the contact pin is interspersed in
In holding chamber and constitute the mating of contact pin and terminal plate.
The beneficial effect of above structure is: being provided on the contact pin of the connector and engages with the arc that wiring board fastens
Portion, the connector and wiring board are when spot welding connects, first in the circuit board by the spot-welding part grafting of contact pin, the arc on weld part
Holding section can engage in the circuit board, can pre-fix the connector in the circuit board, consequently facilitating the connector and wiring board
Spot welding connection, ensure that connected between the connector and wiring board it is more reliable, compact.And terminal plate uses full-enclosed structure,
And be provided in grafting framework contact pin can be pressed on to the intracorporal elastic contact chip of grafting frame, improve the electricity of contact pin and terminal plate
The reliability of connection, and Elastic Contact on piece is provided with the arc-shaped contact part matched with contact pin, being conducive to contact pin can be quick
Ground is plugged in grafting framework, so that the bar connector has the advantages that structure is simple, stable and reliable for performance, connection is reliable.
Particularly, there is anticreep limit film on the lower end surface of the grafting framework, be provided in the terminal base with
The limiting slot that anticreep limit film matches, one end downward bending of anticreep limit film and is fastened in limiting slot, and constitutes terminal
The clamping engagement of piece and terminal base.Anticreep limit film, terminal base and needle stand are provided on terminal plate in mutual timing, terminal plate is not
Easily loosen, ensure that contact pin and being electrically connected for terminal plate are more reliable, and terminal plate connect with terminal base it is more compact.
Detailed description of the invention
Fig. 1 is the utility model embodiment perspective view.
Fig. 2 is the utility model embodiment cross-sectional view.
Fig. 3 is the perspective view of the utility model embodiment terminal plate.
Specific embodiment
As shown in Figures 1 to 3, the utility model embodiment is a kind of bar connector, including needle stand 10, multiple settings in needle
Contact pin 11, terminal base 20, the multiple terminal plates 21 for being arranged in terminal base 20 and being matched with each contact pin 11 in seat 10, it is described
One end of contact pin 11 there is the weld part 111 that is exposed at outside needle stand 10, have on the tail portion of the weld part 111 and mutually block with wiring board
