GENERAL INFORMATION

1.YJQ-W3Q-BM2 is a pneumatic crimp tool unit (including YJQ-W3Q basic tool, BM2 base plate and pneumatic kit, it is widely used for the crimping of wires and contacts in both military and proprietary programs.

2. Wire crimp range:  8AWG (8mm^2) to 18AWG (0.8mm^2).

 

WORKING PRINCIPLES

 

1. Crimping Method

    The crimping tool adopts curve propulsion mechanism, its applied force transfers through four curves in the head cavity of the right plier handle to the four indenters. The four intenders do the centripetal linear motion, which makes its front-end teeth crimp the contact to complete the crimping process. The cycle controlled precision ratchet assures the consistency of impression and the crimping quality of wires and contacts.

 

2. Crimping Range Adjustment

    The crimping tool has eight selector numbers; the accurate data are listed as follows:

Selector NO.	Intender Working Diameter mm/INCH
	A GO	B NO GO
1	0.036/0.91	0.041/1.04
2	0.045/1.14	0.050/1.27
3	0.052/1.32	0.057/1.45
4	0.061/1.55	0.066/1.68
5	0.069/1.75	0.074/1.88
6	0.076/1.93	0.081/2.06
7	0.086/2.18	0.095/2.41
8	0.100/2.54	0.11/2.79

 

3. Gaging Instructions

 “GO” Gaging: keep the tool in fully closed position, insert the green “GO” gage end into the indenter, it should be easy to enter, otherwise, the selector gear is incorrect.

  “NO GO” Gaging: keep the tool in fully closed position, insert the red “NO GO” end into the indenter, it can’t pass through completely, otherwise, the selector gear is incorrect.

(CAUTION! DO NOT CRIMP GAGE!)

 

CRIMPING INSTRUCTIONS

1. Connect the tool frame, base plate, pressure regulating valve and hose as the follow picture.  2. Working air pressure: 80-120 P.S.I.

Maximum pressure: 120 P.S.I.(5.5-8.3BAR)

The positioners should be purchased separately

3. Insert the contact and prepare the wire through the indenter from the opposite side. Supply air for the tool frame by using foot treadle or hand switch. Loosen it after the crimping operation finished.

4. Remove the finished assembly and insert the next contact to be crimped.

 

CAUTIONS

1. Keep the crimping tool and other units clean and properly stored when not in use or no operator maintenance.
2. Don’t try to immerse tools in cleaning solution or spray oil into tools to lubricate.
3. If finding anomalies due to the incorrect ways, don’t attempt to disassemble tools or make repairs. Please stop using it and connect us as soon as possible, our company will offer complete refurbishing and recalibration services.
