Background technology
Along with automobile industry at home developing rapidly and universal, along with automobile body control module (is body control module, be called for short BCM) integrated development, the function that various electronic equipments are applied in vehicle body is more and more, BCM control object is more, function is more powerful, requires the data communication function of BCM also more and more stronger, makes bus type, networking BCM become development trend.
Thereby the user demand of connector in BCM increased increasingly, the main external matured product of dependence on import before, all be subject to the constraint of existing product at the aspect such as structure, technique, cause injection molding process, material, tolerance fit precision etc. to be had relatively high expectations, cause production cost high, efficiency is low, and the high deficiency of scrappage affects the large-scale mass production of product.
Existing terminal compression joint portion is generally slender type needle-like, and when use, the connecting portion of its shoulder and pressure contact portion is easily bending or fracture, and the frictional force of terminal and pcb board is inadequate, cannot locate, and can not ensure the reliable connection of signal between electronic component.
Chinese patent CN203103573U discloses a kind of sidewall concave type flake terminal, one end and pcb board are welded to connect, the other end is connected inserting with wire harness terminal adapter, form electrical circuit, realize the data communication between each electric component, sidewall concave type flake terminal bodies is cross structure, and the left and right sides of the upper end of this cross structure offers the groove caving inward.This structure has avoided terminal to interfere transition and mechanical performance surrender under strong stress, but this structure does not have location structure, and has much room for improvement with pcb board contact reliability.
Utility model content
The purpose of this utility model is exactly that a kind of simple in structure, flake terminal of being connected reliable pressure contact portion with pcb board and being provided with fin is provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pressure contact portion is provided with the flake terminal of fin, comprise the connecting portion, shoulder and the pressure contact portion that set gradually from down to up, described pressure contact portion is for pegging graft with pcb board, form connector, with conductive electrical signal, described pressure contact portion is hollow flat shape body, and former and later two surfaces of pressure contact portion are horizontal plane, the side, two of left and right of pressure contact portion is curved surface, and is respectively equipped with 2 longitudinal fins on side, two of the left and right of pressure contact portion.
Described pressure contact portion is elastic component.
2 fins on pressure contact portion same side are parallel to each other.
Described fin is circle shape fin or pointed fin.
The height of described fin is identical with the height of pressure contact portion.
Described fin is positioned at the middle part of pressure contact portion, and length is 1/3～2/3 of pressure contact portion height.
Compared with prior art, the utlity model has following advantage:
(1) the flake terminal of employing new structure, its rigidity reinforced, can locate preferably, thereby has ensured the reliable connection of signal between electronic component.
(2) on the side, two of left and right of pressure contact portion, be respectively equipped with 2 longitudinal fins, can realize the interference of putting with face with pcb board through-hole wall, terminal is difficult for upset in pcb board through hole, play positioning action, flake is in horizontal direction material production strain in addition, be squeezed in pcb board inwall, increased frictional resistance, thereby ensured the reliable connection of signal between electronic component.
(3) flake terminal of the present utility model forms a connector by the mode of inserting connector shell, there is assembling simple, can make connector and pcb board have without welding processing procedure is connected closely with conductive electrical signal, connector has substitutability in addition, if this connector damages, can directly remove from pcb board, change another new connector, there is the features such as stable, simple, convenient, fast.
