Abstract

The utility model relates to a socket needle type electrical connector, which comprises an insulating body (1) and a contact pin (2) which is inserted and connected with the insulating body, wherein one end of the contact pin, which is directly connected with a wire is provided with a crimp shaped wiring structure (21). The socket needle type electrical connector overcomes the defects in the prior art that a connector just can be connected with wires must through using a PCB board, a welding end of the contact pin, which is welded on the PCB board is changed into a crimp ring shape, thereby leading the wires to pass through in the welding end, the wire is directly welded on the welding end, thereby reducing the transition of the PCB board and is directly connected with the wires, and saving the use space of the connector. The crimp ring shaped structure also can increase the section area thereof through controlling the width of materials, and improves the influence of directly punching to the section area, reduces the waste of the materials, and achieves the purpose of saving space. On the other side, the contact pin uses a square section structure, thereby leading the contact pin and a clamping piece of a socket female terminal to contact in a wire, increasing the contact area of a conductive part, and leading the ability of transporting current to be greatly increased.

Description

A kind of row's needle electric coupler

Technical field

The utility model relates to a kind of electric connector, relates in particular to a kind of row's needle electric coupler that is used for pcb board.

Background technology

In the electric connector that is applied to surface-mounted integrated circuit (PCB), the application of plug-in type electric connector is very extensive.Wherein arranging needle electric coupler is the simplest a kind of plug-in type electric connector, usually its contact pin is fixed with plastic parts, is welded on the pcb board, will arrange female connectors again and be inserted on its pin, make it finish and arrange female connectors and be connected, its shared space is suitable with the PCB terminal connector; This class connector is generally used for data, the field that current requirements such as signal are not high, its contact pin uses circular contact pin usually, its round pin surface and intermediate plate are to contact, this connector can not satisfy this requirement in the circuit of big current requirements so have, usually this series products contact pin needs pcb board to do transition, is connected with lead again.

Summary of the invention

The technical problems to be solved in the utility model is to be connected electrically in the defective that can not realize the logical loading capability of big electric current in the little space at existing row's pin type, provide a kind of simple in structure, reduce the pcb board design, row's needle electric coupler of the bigger electric current of energy load in little spatial dimension.

In order to solve above technical problem, the technical solution adopted in the utility model is:

Row's needle electric coupler of the present utility model comprises: insulator, with the contact pin that insulator is pegged graft, above-mentioned contact pin and lead directly are weldingly connected to hold and are provided with curling wiring construction.

Further, the set curling wiring construction of the utility model row needle electric coupler is spent circuluses for being curled into 360.

On the other hand, the contact pin of row's needle electric coupler of the present utility model has adopted square cross.

Circulus of the present utility model is circular or oval ring-type or square ring-type.

Contact pin of the present utility model is square contact pin.

By above technical scheme, can realize following beneficial technical effects:

1. the welding ends that contact pin is soldered to pcb board makes the ring-type of curling into, lead can be passed through within it, and lead is directly welded thereon, thereby reduced the transition of pcb board and directly link to each other with lead, has saved the usage space of connector.

2. the circulus of curling can pass through the control material width, increases its sectional area, promotes load capacity, and improves the long-pending and influence that takes up room of direct punching pair cross-section and reduced waste of material, reaches the purpose that promotes load capacity, saving space and cost.

3. on the other hand, its contact pin has adopted square cross.Make its intermediate plate become line to contact, increased the contact area of current-carrying part, thereby the ability of transmission current is increased greatly with row's female terminal.

Fig. 1 is the structural representation of row's needle electric coupler of the present utility model;

Fig. 2 is the end view of row's needle electric coupler of the present utility model.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, row's needle electric coupler of the present utility model is formed by insulator 1 with the contact pin 2 that insulator is pegged graft, and contact pin 2 and wire bonds end are made curl shape, lead can be passed through within it, and lead is directly welded thereon; Contact pin 2 front end plugs place make the contact pin 2 of square-section into, and square pin has bigger sectional area than round pin in little space; Simultaneously the thickness of contact pin 2 is exactly to be the thickness of material, its precision of fine control, and it is stable to be inserted in the intermediate plate of connector contact resistance, and contact pin 2 becomes line to contact with row's female connectors intermediate plate, and contact resistance is few, leads to the loading capability height; More than two aspects its logical loading capability is strengthened.

Can see that from Fig. 2 these contact pin 2 welding endss have curling wiring construction 21, the wiring construction 21 curling 360 that should curl is spent structure circlewise, the axis of circulus is vertical with contact pin 2 plug directions, connect with soldering again in the hole of lead insertion circulus, reduced the transition of PCB like this, avoid having transition piece between lead and the row's needle connector, electrical loss in the middle of reducing, thereby make it that better ducting capacity be arranged, this structure plug contact-making surface is a plate surface, the control easily of size and surface, four sides angle chamfered, guarantee the contact of contact-making surface, reduce contact resistance, and the plane of polishing can have been controlled the contact engaging and separating force of pin better; Wiring construction 21 wiring of curling are shaped easily by the hole, are easy to processing.
