Description
Technical field
It is especially a kind of for detecting the device of automobile connector the present invention relates to the detection device of automobile device.
Background technique
Automobile connector be electronic engineering technical staff often in contact with a kind of component, for be blocked in circuit place or
It isolates between obstructed circuit, erects the bridge of communication, to make current flowing, circuit is made to realize scheduled function.Automobile connects
Card format and structure be it is ever-changing, include mainly shell, be usually provided with contact pin in shell, it is raw to be applied to automobile
In production, unrelated electronic equipment is connected.
Automobile connector generallys use traditional probe when detecting and is tested since structure is relatively simple.But
It is since the probe of conventional probe is larger, when the socket connector pin depth of parallelism cannot be met the requirements, the probe of probe still is able to
It touches with contact pin, is normally tested；That is, conventional probe only can in automobile connector contact pin electrical connection whether
Conducting is detected, and cannot realize the detection of the contact pin depth of parallelism.And the depth of parallelism or the artificial eye judgement of socket connector pin,
It is exactly to carry out optical scanner detection using equipment；But visual inspection subjectivity is strong, and result is unreliable, optical scanner
Although detection is accurate, investment is larger, and common medium-sized and small enterprises are relatively difficult to achieve.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of structures, and automobile connector detection simple, easy to use fills
It sets, on the basis of being able to carry out normally Function detection, realizes the accurate detection of the contact pin depth of parallelism.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of automobile connector detection device, it is described including mutually nested and coaxial arrangement casing and insulation guide post
Central through hole is offered on the central axis for the guide post that insulate, being equipped in central through hole can move back in through-hole along central axis
Dynamic cylindrical metal terminal, one end that metal terminal is located in casing are connected with test conducting wire, and the other end of conducting wire passes through set
The via hole of bottom of the tube stretches out outside casing；The insulation guide post is located at one end outside casing and is provided with cone structure, corresponding center
The truncated cone-shaped targeting port towards casing side, the outboard end diameter of truncated cone-shaped targeting port are provided at the insulation guide post cone angle of through-hole
Greater than metal terminal diameter and it is less than the worst error value range on tested socket connector pin head, the diameter of metal terminal and tested
The diameter on socket connector pin head is identical.
A kind of above-mentioned automobile connector detection device is set between the bottom face of described sleeve pipe and the bottom face for the guide post that insulate
It is equipped with buffering spring.
The junction of a kind of above-mentioned automobile connector detection device, the metal terminal and conducting wire, which is provided with, prevents metal end
Son skids off the limited block of insulation guide post and casing.
Due to using above technical scheme, the invention technological progress is as follows.
The present invention, can be real on the basis of carrying out normally Function detection for detecting to automobile connector
The accurate detection of the existing contact pin depth of parallelism, greatly improves work efficiency and the reliability of product.Wherein insulation guide post outer end
Truncated cone-shaped targeting port setting, it can be achieved that the contact pin depth of parallelism detection；And the setting of spring, can be parallel in socket connector pin
When degree is unsatisfactory for depending on error requirements onto the guide post of targeting port periphery, tested connector is pushed to insulate when for buffering detection
The pressure of guide post prevents from causing contact pin bending deformation, while also being protected to the insulation guide post of detection device.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is use state diagram of the present invention.
Wherein: 1. metal terminals, 2. insulation guide posts, 3. springs, 4. casings, 5. conducting wires, 6. targeting ports, 7. limited blocks,
8. tested socket connector pin.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in further detail.
A kind of automobile connector detection device, structure is as shown in Figure 1, include mutually nested and coaxial arrangement casing 4
It is stretched out outside casing with one end of insulation guide post 2, insulation guide post 2, the other end is located in casing, and the insulation in casing is led
It is provided with spring 3 between 4 bottom face of 2 bottom face of column and casing, the connector for being unsatisfactory for depth of parallelism requirement for buffering contact pin
The thrust that insulation guide post is generated.
The guide post material that insulate requirement is harder, such as PVE rigid plastics etc..In being offered on the central axis for the guide post that insulate
Heart through-hole is equipped with cylindrical metal terminal 1 in central through hole, can in the detection process, in the effect of tested socket connector pin
Move back and forth in through-hole along central axis under power.One end that metal terminal 1 is located in casing is connected with test conducting wire 5, leads
The via hole that the other end of line 5 passes through sleeve bottom stretches out outside casing, and the setting of conducting wire is for testing the conduction property of connector.Gold
The junction for belonging to terminal and conducting wire is provided with limited block 7, for preventing metal terminal from skidding off insulation guide post and casing.
Insulation guide post 2 is located at one end outside casing and is provided with cone structure, the insulation guide post cone of corresponding central through hole
The truncated cone-shaped targeting port 6 towards casing side is provided at angle, the outboard end diameter of truncated cone-shaped targeting port is greater than metal terminal diameter
And it is less than the worst error value range on tested socket connector pin head, the diameter of metal terminal and tested socket connector pin head
Diameter is identical.Under normality, the outer end of metal terminal and the inside end position of truncated cone-shaped targeting port are corresponding.
The present invention is for being inserted into stretching set for the tapered surface that tested connector is directed at insulation guide post when testing connector
In insulation guide post outside pipe, as shown in Figure 2.When the tested socket connector pin depth of parallelism, which is fully met, to be required, pin head is straight
It connects and is contacted with metal terminal, if connector inside conductor is connected, conducting wire will pass out Continuity signal at this time；If patched
Part inside conductor is not turned on, then conducting wire cannot transmit signal, illustrates that tested connector is unqualified.When the tested socket connector pin depth of parallelism
Slightly offset is still in claimed range, and pin head contacts inside targeting port with metal terminal, if led in connector
Line conducting, conducting wire can equally pass out Continuity signal；If connector inside conductor is not turned on, same conducting wire cannot be passed
Delivery signal illustrates that tested connector is unqualified.And when the tested socket connector pin depth of parallelism is not in claimed range, then pin head
It directly outside top to targeting port, cannot be contacted with metal terminal, conducting wire cannot transmit signal, illustrate that tested connector is unqualified.
To sum up, either tested connector general function is unqualified or the depth of parallelism cannot be met the requirements, then this hair
Bright conducting wire is then all unable to output signal, it was demonstrated that the tested connector is rejected product.
