Embodiment

The cable of fire extinguishing series of products is divided into the plug that an end is 17 contacts or 14 contacts usually; The other end is that the plug of some 4 contacts or 3 contacts constitutes; Shown in wherein a kind of construction of cable synoptic diagram of Fig. 1; This cable 9 is made up of the 10, the one No. four plug the 12, the one No. five plug 13 of the 11, the two No. four plug of a plug and the two No. five plug 14 these 5 plugs, and wherein plug 10 plug that is 14 contacts is labeled as A, B, C, D, E, F, G, H, I, J, K, L, M, N respectively; The one No. four plug 11 and the two No. four plug 12 are two plugs with 4 contacts; Be labeled as a, b, c, d and e, f, g, h respectively, the one No. five plug 13 and the two No. five plug 14 are two plugs with 3 contacts, are labeled as i, j, k and l, m, n respectively.

Cable connection like Fig. 2 concerns shown in the synoptic diagram, 14 contacts on plug 10 respectively with 11,12 and two No. five

plugs

13,14 of two No. four plugs on totally 14 contacts connect one to one and form cable 9 with 14 contacts.

Embodiment 1

Shown in this pick-up unit of Fig. 3 structural representation; Mainly constitute, be distributed with first socket 1, second socket 2, indicating device 3, No. four sockets 4, No. five sockets 5, ground connection binding post 6, power switch 7, power-line terminal 8 on the guidance panel 15 by guidance panel 15.

First socket 1 is the socket with 17 contacts; Second socket 2 is the sockets with 14 contacts; Each contact of first socket 1 and second socket 2 all is connected a pilot lamp in the indicating device 3; Totally 31 pilot lamp, each contact of first socket 1 and second socket 2 are connected respectively and are connected in parallel to the negative pole of power-line terminal 8 behind the pilot lamp.

No. four sockets 4 are the sockets with 4 contacts, and No. five sockets 5 are the sockets with 3 contacts, and each contact of No. four sockets 4 and No. five sockets 5 is parallelly connected with an end of power switch 7, and the other end of power switch 7 is electrically connected to the positive pole of power-line terminal 8.

Several pilot lamp in the indicating device 3 in the present embodiment all adopt LED lamp pearl, and power-line terminal 8 provides direct current 27V power supply.

During detection, the two ends plug of the cable 9 that needs are detected is inserted into respectively on the corresponding socket, for example detects the annexation between plug 10 with 17 contacts and the one No. four plug 11:

Plug 10 of cable that needs are detected is inserted on first socket 1; The one No. four plug 11 is inserted on the socket of No. four sockets 4; Then; Turn on the

power switch

7,4 LED lamp pearls of A in plug 10 of cable, B, C, 4 contact series connection on first socket 1 that D is corresponding should be lighted, if the LED lamp pearl of the A point correspondence among these 4 of the A, B, C, D is not lighted; Then should check the welding quality that a is ordered on A point on plug 10 of cable and the one No. four plug 11, and whether the lead that connects between these 2 opens circuit.

In like manner, if the annexation between plug 10 of detection streamer and the one No. five plug 13:

Plug 10 of cable that needs are detected is inserted on first socket 1; The one No. five plug 13 is inserted on the socket of No. five sockets 5; Then; Turn on the power switch 7,3 LED lamp pearls of I in plug 10 of cable, J, 3 contact series connection on first socket 1 that K is corresponding should be lighted, if the LED lamp pearl of the J point correspondence among these 3 of the I, J, K is not lighted; Then should check the welding quality that j is ordered on J point on plug 10 of cable and the one No. five plug 13, and whether the lead that connects between these 2 opens circuit.

As detection have 14 contacts plug and and its No. four plugs between annexation, a plug 10 of cable that only needs to detect is inserted on second socket 2, No. four plugs are inserted into that energized gets final product on the socket of No. four sockets 4.

Promptly The present invention be directed to every lead in the cable conducting, open circuit, performance detection and qualification determination such as ground connection.Take the mode of each contact respective leds of main plug in cable illumination is shown that filter out contact or earth point that cable should conducting when energising, diode is lighted when welding is correct; Do not answer the contact of conducting, diode is not lighted.Detect cable product and make state, judge the whether qualified of cable product, investigate out the wrong connecting point position of welding in the cable.
