Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of gauge for detecting inline device plug pins.
Background technology
Inline device is different from general electricity consumption product, and it refers to that self is with the product of plug pins that can insert socket, if namely a large amount of charger for mobile phone is inline device.In the manufacture process of its plug, due to a variety of causes such as technique, equipment, and there is the undesirable situation of plug slice length, the potential safety hazard in bringing user to use, therefore need to carry out plug pin lengths detection to the plug after having manufactured.
As Chinese patent literature CN202661033U discloses a kind of equipment measuring plug slice, comprise the tool module for inserting plug to be checked and control display module, by inserted sheet detection line and bus between described tool module and control display module, in wherein said tool module hole, the end of predetermined length is provided with sensing chip, the other end of described sensing chip is connected with inserted sheet detection line, described jack side has common port and is connected with concentric line, and described control display module is provided with the wiring point of each inserted sheet detection line corresponding and bus respectively.Namely in the equipment of the measurement plug slice described in above-mentioned patent documentation, when inserted sheet inserts jack, if inserted sheet length is qualified, then inserted sheet is connected with sensing chip and common port simultaneously, thus make inserted sheet, inserted sheet detection line, bus be communicated with formation loop with control display module, and qualified by controlling display module prompting operator product; Meanwhile, described control display module is provided with each inserted sheet detection line corresponding and bus wiring point respectively, and handled easily people understands specifically which product existing problem.
But the equipment of the measurement plug slice described in above-mentioned patent documentation be mainly applicable to test plug whether expose latch too short, with prevent user in use occur plug and female contact bad; This kind measures the equipment of plug slice and whether be not suitable for test plug inserted sheet long.And plug pins is long, for inline device plug there is Danger Electric shock risk, as long in the latch when plug, when may occur that latch has touched the conducting metal of socket, finger also may touch the phenomenon of latch root, user is easily caused to get an electric shock, cause personal injury, potential safety hazard is huge.
Standard GB1002-2008 " family expenses and similar applications Single-phase plug Socket Type, basic parameter and size " has a kind of gauge " not contacting rule ", its specified length Esg is 8.450-0.05mm, namely plug is not before insertion socket is more than the 8.40mm degree of depth, plug does not allow live part in contact base, and namely plug is cold.If continue again to insert, be namely energized, make plug become live part, if now code test refers to still can touch latch, then illustrate that this plug does not meet protection against electric shock requirement, judge defective; That is, in order to ensure that user in use can not get an electric shock because plug pins is long, need to ensure that plug pins plug pins when inserting socket 8.40mm is not charged, or the structure of the host plastic part of inline device can stop test to refer to touch the latch having become live part.
Whether the socket panel that in prior art, general employing market is sold and the mode that sheet metal cooperatively interacts carry out test plug latch long, by socket panel and sheet metal up and down superposition screw be connected, and ensure that distance between socket panel to sheet metal is just in time degree of depth 8.40mm that standard specifies, then by the plug insertion socket panel of inline device to latch contacting metal plate, next code test is referred to insert in the gap between plug and socket panel, detect whether it qualified.
Although the mode that above-mentioned socket panel and sheet metal cooperatively interact can detect whether plug pins is long, but there is following problem in it: in which, the adjustment of height 8.40mm is by regulating manually, thus there is human factor, everyone operating result may be inconsistent, same people's multi-pass operations also may be inconsistent, when causing actual detection, easily occur error, testing result is unstable.
Utility model content
For this reason, technical problem to be solved in the utility model is that need to cooperatively interact between two parts, thus easily occur error, testing result is unstable in prior art when whether the plug pins detecting inline device is long; And then provide a kind of being applicable to detect the whether long inline device plug pins gauge of direct insertion plug pins.
