In mounting groove.
The utility model is further improved, and is additionally provided with key hole on the upper casing, the key hole with wiring board
Key position is corresponding.
Compared with prior art, the beneficial effects of the utility model are：It need not tear open, welding lead, reduce the time, lifting
Efficiency；Download efficiency significantly improves, and bonding wire, which is downloaded, before needs 1-2 minutes to have downloaded one, now only needs 15 seconds left sides
It is right.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is Fig. 1 right views；
Fig. 3 be and computer connected interface schematic diagram；
Fig. 4 is circuit board structure schematic diagram.
Embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As Figure 1-Figure 4, the utility model includes shell 1, and being arranged on shell 1 to be used to install includes single-chip microcomputer line
The mounting groove 2 of road plate, the shell of the side of mounting groove 2 are provided with test thimble 4, wherein, the test thimble 4 comprises at least
Pin number identical pin, when the wiring board 8 is installed into the mounting groove 2, the pin and list are downloaded with single-chip microcomputer
The download Pin locations of piece machine are corresponding, and can electrically connect, and drawn on the pin and pin number identical wire 6, institute
State the other end of wire 6 and be provided with the interface 7 being connected with computer.
As shown in figure 4, as one embodiment of the present utility model, the single-chip microcomputer that bidirectional anti-theft alarm uses is STM8
Single-chip microcomputer, STM8 single-chip microcomputers U1019 with ST-LINK modes when being downloaded, it is necessary to which 4 lines meet VCC（3.3V）、GND、SWIM、
This 4 underfooting of NRST carry, and therefore, the test thimble of this example includes 44 downloads being used for STM8 single-chip microcomputers U1019 and drawn
The connected pin of pin, respectively VDD pins 41, GND pin 42, SWIM pins 43 and NRST pins 44.Then PCBA pairs is passed through
The shell answered draws this four lines, directly connects computer download, the step of eliminating every plank welding lead, without
Tear open, welding lead, reduce the time, raising efficiency；Download efficiency significantly improves, before bonding wire download need 1-2 minutes could under
One has been carried, has been now only needed 15 seconds or so.
Further, it is described test thimble 4 also include 2 signal input and output pins, respectively with the TX of STM8 single-chip microcomputers
It is corresponding with RX pins, consequently facilitating the transmission of signal.
Preferably, the shell 1 of this example includes upper casing and lower casing, and the upper casing encloses with lower casing and accommodates the wiring board
