Embodiment
Main conception of the present utility model is a kind of deflection pick-up unit of design, and it utilizes simple projection and gap design, cooperates easy sensing loop again, replaces complicated operation and expensive instrument and equipment, and then improves detection efficiency.Below lift a preferred embodiment, this device is applied to power connector elaborates.
Please refer to Fig. 1, it illustrates a kind of partial schematic diagram of power connector.The design of power connector is to adopt Embedded slot 100; and in order to differentiate polarity; general all can be designed to long ground connection pin 120 and an a plurality of short power pin 110, and ground connection pin 120 and a plurality of short power pin 110 are arranged in the slot with the protection pin.Yet long ground connection pin 120 is subjected to external force to produce deflection during often because of carrying, so the most often be regarded as pin to be measured.
Please refer to Fig. 2, it illustrates the perspective view according to the deflection pick-up unit of the utility model one preferred embodiment.Pick-up unit comprises: detecting device 200 and sensor 300.Sensor 300 is electrically connected with detecting device 200, for example connects sensor 300 and detecting device 200 by a lead 250.Detecting device 200 comprises: body 210, first projection 220 and second projection 230.Have a grip part on the body 210, provide convenient gripping of testing staff to detect, preferable design is to use flat board, because flat board can also be bearing on casing to increase the stability of pick-up unit, as shown in Figure 2 when detecting.First projection 220 and second projection 230 protrude in a side of body 210, in order to be inserted in the Embedded slot 100 of power connector, so the size of first projection 220 and second projection 230 must be done interference engagement with slot 100, to improve the accuracy of pick-up unit.In addition, first projection 220 and second projection 230 are at a distance of a gap 240, and this gap 240 is in order to detect ground connection pin 120, so the width in gap 240 needs the width greater than ground connection pin 120.
Please be simultaneously with reference to Fig. 3 and Fig. 4.It illustrates deflection pick-up unit according to the utility model one preferred embodiment in the partial schematic diagram of detected state Fig. 3.It illustrates deflection pick-up unit according to the utility model one preferred embodiment in the side cutaway view of detected state Fig. 4.When detecting, when first projection 220 and second projection 230 are inserted in the slot 100 of power connector, if the ground connection pin 120 in the slot 100 is under normal no deflected condition, this ground connection pin 120 will be inserted in the gap 240, and can not touch first projection 220 or second projection 230, and make power pin 110 be adjacent to first projection 220 or second projection 230; If when the ground connection pin in the slot 100 120 produced deflected condition, this ground connection pin 120 will touch first projection 220 or second projection 230.Yet first projection 220 and second projection 230 all are conductive projection, thus first projection 220 or second projection 230 therewith ground connection pin 120 touch, will make detecting device 200 form a short circuit, that is present the state of conducting.At this moment, the sensor 300 of Fig. 2 senses detecting device 200 and exports a sensing signal for short circuit.But sensor 300 can be the device of an ammeter, an illuminator or other sensing short circuit, and exports different sensing signals according to the difference of its device.If sensor is when being ammeter, then sensing signal is an electric signal, and ammeter can send the sound and informs that this pin to be measured of tester is by test.When if sensor is illuminator, for example be that (Light Emitting Diode, LED), then sensing signal is a light signal, that is illuminator can luminously inform that this pin to be measured of tester is not by test for bulb or light emitting diode.And sensing signal also can be a voice signal, in order to inform that this pin to be measured of tester is not by test.
Yet have in the technical field under the present embodiment and know that usually the knowledgeable can understand that also the technology of present embodiment is not confined to this.This pick-up unit can be applicable to that the deflection of various connector pins detects, for example: the power connector of knife edge type server (blade server) or the attaching plug of electrical appliance etc.In addition, if need to transmit bigger electric current, also pin can be changed into is metal clips.At manufacture view, detecting device can be one-body molded, also can be made into movable projection, but because steel are not fragile, the cost of material is low and easily manufactured, so detecting device preferably is formed in one.The practice application is gone up according to the width of the slot size of various connectors and pin to be measured and has been made into several detecting devices with projection of different size and different gap.In addition, the design of interstitial site more can be according to long pin to be measured and other relative position of short pin and adjustment to some extent.
The disclosed deflection pick-up unit of the utility model the foregoing description has following advantage:
Cost is low: because detecting device can be one-body molded, and preferably use non-damageable steel, need not buy expensive optical instrument, so can reduce manufacturing cost.
The accuracy height: the contact measured pin is dwindling its sensing range for the projection by detecting device, and projection and slot be designed to interference engagement and make it fixing more accurate, and then improve accuracy.
Detect fast:,, can learn testing result fast as long as sensor can directly be exported sensing signal when deflection occurring because detecting device is a simple loop design with sensor, and need not to obtain the result by the calculating and the analysis of complexity.
Processing ease: the method for operating of this detection is very simple, need not the complicated operations process and is subjected to the training of any special professional knowledge or technical ability, and everybody can be competent at.
