Abstract
The utility model relates to a double-surface soldering automobile connector. The two ends of the connector are both soldered on and connected with PCBs. Therefore, a double-layer board assembly is formed in order to achieve a circuit loop between the two layers PCBs. The connector is formed by a plastic housing and contact terminals. The plastic housing is a housing formed by injection molding technology. Positioning holes are disposed on the housing. The contact terminals are stamped double-step interference fit structures and are clamped to the plastic housing. Compared with a product in the prior art, the automobile connector improves the assembly interference structure of the terminals and a injection molding member so as to be capable of increasing production efficiency, reducing cost, and increasing product reliability.
Description
Technical field
The utility model relates to a kind of connector, especially relates to a kind of two-sided solder type automotive connector.
Background technology
Along with automobile industry developing rapidly and popularizing at home, the demand of automotive connector increases day by day, and the main before external matured product of dependence on import all is subjected to the constraint of existing product at aspects such as structure, technologies, have certain unworthiness.Particularity such as structure, cause that terminal confining force in moulding is less than normal, the product moulding is arranged up and down and the terminal cooperation place difficult apart from crossing the prepackage of ambassador's terminal and following plastic removal glue cooperation place, and ITCH is too small because of product P, general vertical hangnail interference structure makes entire product moulding cracking, assembling back product warpage is bad, or the like problem cause the production cost height, efficient is low, the high deficiency of scrappage influences the large-scale mass production of product.
The utility model content
The purpose of this utility model is exactly to provide a kind of assembling interference structure of terminal and moulding that improves to enhance productivity, reduce cost, to improve the two-sided solder type automotive connector of product reliability for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of two-sided solder type automotive connector, the two ends of this connector all are welded to connect with PCB, form the doubling plate assembly, realize the circuit loop between the two-layer pcb board, and described connector is made up of plastic casing and contact terminal,
Described plastic casing is the housing of injection mo(u)lding, offers location hole on housing;
Described contact terminal is the excessive interference structure of rammed pair of ladder, and card is established and is connected on the plastic casing.
The top of described contact terminal is provided with a convex section.
Described convex section interference is connected in the location hole of offering on the plastic casing.
Described location hole offers two rows.
Compared with prior art, the utility model has improved the assembling interference structure of terminal and moulding, thereby can enhance productivity, reduce cost, improve product reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of plastic casing;
Fig. 3 is the structural representation of contact terminal.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of two-sided solder type automotive connector, the two ends of this connector all are welded to connect with PCB, form the doubling plate assembly, realize the circuit loop between the two-layer pcb board, and described connector is made up of plastic casing 1 and contact terminal 2, and its structure is as shown in Figure 1.Plastic casing 1 is the housing of injection mo(u)lding, offers location hole on housing, and location hole offers two rows, as shown in Figure 2.Contact terminal 2 is the excessive interference structure of rammed pair of ladder, is provided with a convex section on the top of contact terminal 2, and as shown in Figure 3, contact terminal 2 cards are established and are connected on the plastic casing 1, and the convex section interference is connected in the location hole of offering on the plastic casing.
The utility model is designed to two stage excessive interference structures with contact terminal 2, contact terminal 2 is when assembling from top to bottom with plastic casing 1 during first stage, the strip structure section of contact terminal 2 plays guide effect, when being assembled to convex section and in a small amount interference and lead simultaneously and a large amount of interference fit are provided of plastic cement, to satisfy the terminal confining force, product with stable quality and reliability are improved.The confining force of the product terminal that making obtains adopts two stage excessive interference structures to guarantee, product structure is with respect to terminal hangnail interfere type commonly used in the prior art, the horizontal terminal of general modfel is interfered change vertical terminal into and interfere.
