Column can as shown in Fig. 2 the side of the contact jaw 312 with for smooth by cambered surface 313 with the end face that chip 100 contacts
Transition is connected, and the external diameter of the cambered surface 313 is pointed to the direction of the end face for being contacted with chip 100 by the side and sequentially passed
Subtract, the direction can refer to the F directions in Fig. 3.
As preferable scheme, in order that must identify that a multiple probe 3 can contact more firm, institute with chip 100
Installation portion 32 is stated to be connected in a manner of mobilizable with contact site 31.Specifically, the installation portion 32 is for hollow column and extremely
Few one end open.Preferably, one end that the installation portion 32 is open extends the outside of installing space 110.The connection end 311
It is interspersed in a manner of mobilizable in installation portion 32, and the contact site 31 extends the outside of the openend of installation portion 32.Work as institute
State after probe 3 contacts with chip 100, promote identification head to be moved towards the direction of chip 100 by external force, can cause described
Connection end 311 is in the internal slide of installation portion 32, so that the contraction in length of probe 3, can so first to connect with chip 100
The tactile contraction in length of probe 3 is bigger, and the probe 3 contacted after guarantee also can be contacted preferably with chip 100.
In order that obtaining the probe 3 can automatically reset after shortening, the probe also includes elastic component（Do not show in figure
Go out）；The elastic component is arranged in contact site 31, and is contacted with the connection end 311.Specifically, when the probe 3 shortens
The elastic component is in compressive state, when external force is revoked, can be automatically reset by elastic component probe 3 to reset condition.
The elastic component can be spring.Probe 3 and chip can be worked as by being contacted by elastic component with the connection end 311 of contact site 31
During 100 contact, both contact jaws 312 preferably contact with the terminal 101 on chip 100.
Due to when probe 3 contacts with chip 100, it will usually certain thrust be present, so as to use a period of time
Probe 3 easily loosens afterwards.Preferably, in order to prevent probe 3 from loosening, the identification head of the present embodiment can also include positioning
Plate 4.The location-plate 4 is installed in housing 1, and the probe is installed on the location-plate 4.Probe 3 can be determined by location-plate 4
On housing 1, prevent probe 3 from occurring situation about loosening after a certain period of use time.Preferably, the quantity of the location-plate 4
Including two or more.Communication line is provided with least one location-plate 4, the probe 3 passes through described logical
Letter circuit connects with the circuit board 2.The communication line is both turned on probe 3 and circuit board 2 so that signal can communicate
Transmitted between circuit, probe 3 and circuit board 2.
Each location-plate 4 is abreast arranged in housing 1.Perforation is offered respectively on each location-plate 4.The spy
Pin 3 passes through the perforation of each location-plate.Preferably, the installation portion 32 passes through the perforation of each location-plate, and
Installation portion 32 is fixedly connected with the location-plate 4.Probe 3 is more steady to be positioned such that to probe 3 by multiple location-plates 4
Gu prevent that the phenomenon loosened occurs in probe 3 after a certain period of use time.Each probe 3 is vertically arranged with the location-plate 4 respectively.
The location-plate 4 be interspersed in installing space 110 and with the clamping of bayonet socket 113.
In summary, identification head described in the utility model is by the way that the maximum outside diameter of contact jaw 312 of at least one probe 3 is increased
Greatly so that its can smoothly with the good contact of chip 100 with thru-hole termination 101.The shape of through holes of the terminal 101 can be
Circle, polygon, D fonts or ellipse etc..It is described in the utility model identification head certainly still can with the absence of through hole end
The chip 100 of son 101 contacts, by the way that the maximum outside diameter of of one or more of which contact jaw 312 is increased equivalent to increasing
Contact area when big contact jaw 312 contacts with the terminal 101 of chip 100, the contact jaw 312 and core of probe 3 can make it that
The terminal 101 of piece 100 contacts more preferable.Therefore the utility model is outer by the maximum for increasing one or more contact jaw 312
Footpath so that the identification head can be common to further types of chip 100, and can also cause the terminal 101 of probe 3 and chip 100
Contact is more preferable.In addition pass through and increase the maximum outside diameter of of contact jaw 312 of part probe 3 so that corresponding probe 3 and other
Probe 3 stores difference in shape, avoids reversed phenomenon occur when probe 3 is contacted with the terminal 101 of chip 100, enters
And improve the practicality of identification head.It should be noted that identification head described in the utility model can make separately as identification head
With can also be connected to being used on multi-functional burning chip device or identifier.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
