Abstract
The utility model provides a crimping test head for electrical signal detection, which comprises a plastic matrix and a pair of metal test connection poles which are embedded in the plastic matrix. Positioning pins (4) and positioning pin holes (5) are mutually matched and are arranged in corresponding positions on the front side and the rear side embedded outside the plastic matrix (1). The positioning pins (4) and the positioning pin holes (5) are arranged into two groups in parallel. Isolation rings (3) are added at probe patchhole ends of the pair of metal test connection poles of the plastic matrix. The height of the isolation rings (3) is 3 mm to 5 mm. The crimping test head ensures that the wrong installation direction does not occur during operation, meanwhile, test heads on a test installation plate are mutually correlative so as to play a stable role. The isolation rings at the probe patchhole ends betters the insulating property between probe patchholes, thus preventing signal crosstalk and test error.
Description
Technical field
The utility model relates to a kind of electrical signal detection crimping measuring head, when being used for field such as communication rack electrical signal detection, and the web member that the testing tool probe is pegged graft.
Background technology
Because the application of the fast-developing and various electronic control systems of communication and network, a lot of occasions need be carried out the electric connection point of reactive system performance with machine testing, so that the operate as normal of safeguards system is in time handled in the orientation of in time understanding system health and may breaking down.
At present, detection to various control racks such as communication, networks, adopt a kind of crimping measuring head, pair of metal test in it comprises plastic substrate and is embedded in plastic substrate is connected the utmost point, the end connection-peg that metallic test connects the utmost point stretches out outside the plastic substrate, the other end that metallic test connects the utmost point is the testing tool probe inlet, and the aperture of testing tool probe inlet and plastic substrate end face are in one plane.Arrange because the polarity that test signal is every group is rule, require each metallic test to be connected the direction unanimity of the utmost point.Existing crimping measuring head both sides are the same, in use easily adorn wrong direction.Simultaneously, the aperture of testing tool probe inlet and plastic substrate end face in one plane easily produce signal and disturb.
Summary of the invention
The purpose of this utility model is a kind of electrical signal detection crimping measuring head of design, solves easily to adorn wrong direction in the use of existing crimping measuring head and easily produce the problem that signal disturbs.
The technical solution of the utility model: the pair of metal test in electrical signal detection crimping measuring head of the present utility model comprises plastic substrate and is embedded in plastic substrate is connected the utmost point, and the register pin and the dowel hole of mutual coupling is set at both sides, the front and back correspondence position that is embedded in the plastic substrate outside.
Described electrical signal detection crimping measuring head, the plastic substrate place that connects the probe inlet end of the utmost point in the pair of metal test is added with cage ring.
Further, register pin and the dowel hole in the both sides, front and back that are embedded in the plastic substrate outside has two groups that be arranged in parallel.
Further, the high 3～5mm of described cage ring.
Advantage of the present utility model: the utility model has not only guaranteed in use can not adorn wrong direction, and simultaneously, the measuring head on a test installing plate is interrelated, plays stable effect.The cage ring at probe inlet end place makes between the probe inlet insulating property better, prevents signal cross-talk and test error.

Embodiment
Fig. 1, Fig. 2 are structural front view of the present utility model:
Pair of metal test in electrical signal detection crimping measuring head of the present utility model comprises plastic substrate 1 and is embedded in plastic substrate is connected the utmost point 2, the end that metallic test connects the utmost point 2 is the outside that connection-peg 2a stretches out plastic substrate 1, the other end that metallic test connects the utmost point 2 is testing tool probe inlet 2b, and the register pin 4 and the dowel hole 5 of mutual coupling is set at both sides, the front and back correspondence position that is embedded in plastic substrate 1 outside.1a is the convex platform of plastic substrate 1.
Further, be added with cage ring 3 at the plastic substrate place that pair of metal test connects the probe inlet end of the utmost point.
Preferably, register pin 4 and the dowel hole 5 in the both sides, front and back that are embedded in plastic substrate 1 outside has two groups that be arranged in parallel.
Preferably, described cage ring 3 high 3～5mm.
Fig. 3 is to use constitutional diagram: during use, the register pin 4 of an electrical signal detection crimping measuring head B is inserted in a part in the dowel hole of adjacent another electrical signal detection crimping measuring head A, and is interrelated, plays stable effect.
Fig. 4, Fig. 5 are that the testing tool probe inserts structural representation of the present utility model:
The cage ring 3 at probe inlet end place makes testing tool probe 6 insert position stability among the probe inlet 2b, and insulating property are better between the probe inlet, prevent signal cross-talk and test error.
