Description
[technical field]
The present invention refers in particular to a kind of electric connector that has switch terminal and be used for signal testing about a kind of electric connector.
[background technology]
Science and technology is maked rapid progress; The variation of product design also more and more is difficult to the imagination, but change a trend is always arranged, and an important trend dimensionally; That is exactly that weight is lighter, thickness will more approach, length is shorter, size is littler; But four above-mentioned big emphasis, but along with the variation of function, mechanism complicated and more augment difficulty.In communications industry; Coaxial connector is a connector that often is used in the mobile phone; Since the mobile phone of a new generation be asked to have only several centimeters less than thickness, the therefore also compelled microminiaturization of wherein employed various electric connectors, so its project organization has also produced greatest variation.
For example a kind of coaxial connector, it is installed on the high-frequency circuit that is provided with ground contact and signal contact, and comprise insulating body, be contained in fixed terminal, movable terminal in the insulating body, and the lid that places the insulating body top.Wherein movable terminal be with high-frequency circuit board on the input end signal contact electrically connect; And fixed terminal be with high-frequency circuit board on the output end signal contact electrically connect; One end of the free end of movable terminal and fixed terminal is in the direction Elastic Contact perpendicular to high-frequency circuit board; And when test probe vertically inserts; The free end of movable terminal electrically disconnects with fixed terminal under the pushing and pressing of test probe, and at this moment, the circuit signal of high-frequency circuit intralamellar part can conduct to external circuit along test probe by the input signal contact.This kind coaxial connector mainly is 3mm * 3mm * 1.8mm at size form now, but this size form can not meet the compact development trend of product, and this just needs the product of a kind of miniaturization more of design.But; When reducing the coaxial connector size; Need to consider whether coaxial connector has normal service behaviour after miniaturization; For example when the height of above-mentioned coaxial connector reduced, whether its insulating body inside had the impulse stroke that enough spaces guarantee movable terminal, and the movable terminal that lets how can be big as far as possible in smaller space has bigger activity space; And how guaranteeing the electrical contact stabilization of terminal in the inner space, all is all difficult problems that coaxial connector brings after miniaturization.
Therefore, a kind of electric connector that can address the above problem need be provided.
[summary of the invention]
The technical problem that the present invention will solve is to make electric connector after miniaturization, can keep the internal terminal stability in contact and bring enough activity spaces to internal terminal.
Electric connector of the present invention; In order to match with test probe, comprise insulating base, conducting terminal and insulating body, wherein said insulating base is provided with the receiving space of accommodating conducting terminal; Insulating body is provided with the exploration hole of accommodating test probe; Conducting terminal includes fixed terminal and movable terminal, and movable terminal is provided with the top, and the top is extended with elastic portion and compressed tablets; Fixed terminal is provided with a pressing part, and pressing part is parallel to press on the compressed tablets, wherein convexes with at least one location convex closure at least one compressed tablets of movable terminal, and the pressing part of fixed terminal is provided with location notch; The location convex closure of movable terminal is fastened in the location notch of fixed terminal, and the part that compressed tablets is positioned at location convex closure periphery closely contacts with the pressing part of location notch periphery; The location convex closure breaks away from location notch,, when test probe withdraws from; When test probe contacts and presses down the top of movable terminal; The top moves down; Drive the compressed tablets of movable terminal and the pressing part of fixed terminal and be separated, the location convex closure breaks away from location notch, when test probe withdraws from; Compressed tablets resets under the elastic force effect of elastic portion, and the location convex closure is fastened in the location notch of fixed terminal.
Compared with prior art; Cooperating of the location convex closure of the location notch of electric connector fixed terminal of the present invention and movable terminal; Make at electric connector after the process repeatedly test of test probe; Connection between its fixed terminal and the movable terminal is still reliable, is not easy to produce deflection and the survey of generation mistake.
