Abstract
The utility model relates to a simple testing probe mounted in testing mould for testing the open or close of the testing breadboard. The utility model consists of a universal probe in the testing mould, the top end of the universal probe touches the testing points of the testing breadboard waiting for inspection; the bottom end of the universal probe is connected with the conducting line arranged externally through a slingshot, the bottom end of the universal probe is combined with the other end of the slingshot; as the slingshot is a tambour shaped slingshot with two smaller ends and a bigger bosom, when in use, powder produced in the inner wall of a mould base bore fall naturally and do not store on the joint point of the slingshot and the universal probe to influence the accuracy of the test; the slingshot and the universal probe can be connected with in tight screw type or in movable connection, thus fitting different requirements of testing breadboards.
Description
Technical field
The utility model relates to and being installed in the testing mould, is used for the plain type testing needle of the break-make road situation of detection line plate.
Background technology
The testing needle that present measurement circuit plate is in the industry adopted, mostly be to realize by the catapult that general pin is mated, catapult top one end directly joins with general pin one end, and described catapult is a kind of catapult that is contracted in gradually by the top, in contract top inconsistent (as shown in Figure 1) of place and general pin bottom, there is following defective in it: one, in the process of measurement circuit plate, the rim of a cup shape owing to contract in the catapult top in the die holder is, and touch mutually with general pin, during work, catapult flexible with die holder on the powder that produces of hole wall friction more easily accumulate in the rim of a cup, when general pin contacts with catapult, powder makes general pin be difficult to conducting, and mistake survey (as shown in Figure 2) occurs.Two, contract rim of a cup shape catapult in this top is in manufacture craft, because of satisfying of the requirement of a catapult top internal diameter of locating less than the diameter of general pin, so in the process of the rolling big and difficulty that is shaped of cast amount of being hit by a bullet, and the length requirement of general pin is between 20mm-110mm, thereby improved production cost greatly.
Summary of the invention
At above-mentioned defective, the purpose of this utility model provide a kind of conductive performance height, test accurately, long, manufacture difficulty of catapult life-span and the low plain type testing needle of production cost.
The technical solution of the utility model: plain type testing needle, comprise the general pin that is arranged in testing mould, each test point is inconsistent on general pin top end and the wiring board to be measured, general pin bottom end is joined by catapult and external lead, it is characterized in that: general pin bottom end and catapult one end mutually combine, the catapult that described and general pin engages is that two ends are smaller, cydariform catapult broad in the middle.
The joint of above-mentioned described general pin and catapult is provided with groove shape connector, and the cydariform catapult is connected with the connector close-fitting.
The end that general pin described in the utility model engages with catapult is coniform, and engages with catapult is movable.
The external diameter of described in the utility model and general pin joint catapult is less than or equal to the diameter of general pin.
Adopt technique scheme, because catapult is that two ends are smaller, cydariform catapult broad in the middle, during work, the powder that the die holder inner hole wall produces can fall by nature, can not lodge in the joint of catapult and general pin and influences the accuracy of test; And catapult has close-fitting to be connected with the juncture of general pin and flexibly connects, and can be fit to the different requirements of measurement circuit plate.Described catapult is simple in structure, and technological requirement is lower, and the general pin length that is mated can shorten to 4mm-20mm, thus the production cost that reduces greatly.

Embodiment
As shown in Figure 1, 2, 3, the testing needle that existing measurement circuit plate is adopted, how cooperate with catapult and form by general pin, described catapult is a kind of catapult that is contracted in gradually by the top, in the top inconsistent of place and general pin bottom that contract, the internal diameter of catapult is greater than the diameter of general pin, so hole inwall and the fricative powder of catapult more easily be accumulated in the rim of a cup place of catapult, causes test failure.
As Fig. 4, shown in Figure 5, the utility model comprises the general pin 2 that is arranged in testing mould, each test point 4 is inconsistent on general pin 2 top end and the wiring board to be measured 1, its bottom end has groove shape connector 21, and cydariform catapult 3 one ends are anchored on the connector 6, are the shape that closely cooperates, thereby increased mutual surface of contact, make general pin 2 send signal clearly to catapult 3, catapult 3 other ends and external lead 5 join, and the external diameter of described catapult 3 is slightly less than or equals the diameter of general pin 2.
During the measurement circuit plate, wiring board 1 presses down, and pressure is passed on the cydariform catapult 3 equably by general pin 2, and simultaneously the electric signal passes through tested points 4 general pin 2 of flowing through is delivered to external processor through lead 5, thereby realizes test.After test is finished, move on the wiring board 1, general pin 2 resets.
Shown in Fig. 6,7,8, general pin 2 described in the utility model is flexible connection with cydariform catapult 3, general pin 2 bottom end are coniform, easily cooperate with catapult 3 and fix, when general pin 2 pressurizeds moved down, general pin 2 bottom end all can be fixed in the catapult 3, and the external diameter of catapult 3 is slightly less than or equals the diameter of general pin 2, the mistake of having avoided the fricative powder of catapult 3 hole walls and having occurred is surveyed, and because general pin 2 engages for movable with catapult 3, the replacing of general pin is more convenient, quick.
Claims (4)
1, the plain type testing needle, comprise the general pin (2) that is arranged in testing mould, it is inconsistent that general pin (2) top end and wiring board to be measured (1) are gone up each test point (4), general pin (2) bottom end is joined by catapult (3) and external lead (5), it is characterized in that: an end of general pin (2) bottom end and catapult (3) mutually combines, and the catapult (3) that described and general pin (2) engages is smaller, the broad in the middle cydariform catapult in two ends.
