Pros and cons of cable joint identification of several points of experience

1, f-lock side must be pierced in the threaded shaft in
F head locking set within the non-through (female) thread the threaded side near the bottom must be processed in a circle cutout slot, so that the thread tapping, Branch Manager, distributor connector (external screw) to Rotary, clamping the cable bushing is not loose, good contacts can remain permanently. Some manufacturers produce inferior f head, no hollow trough is processing, branch and the distributor connector is often difficult to spin, not compacted cable sleeving, may cause poor contact failures as time went by and extremely difficult to find out; or connector to be spinning in place, increase the force tends to cause branching, and distributor connector thread damage, in particular aluminium threaded. Due to hollow f head locking sleeve inside the bottom of the less attention, often being used by quality control personnel and convicted.
2, f-head pins with insulated panels and joints to static between the shell meet
Ordinary f-9,-12 head, usually equipped with a PIN, PIN pin is divided into front-end and back-end of the cable conductor casing into two parts, between these two parts and insulation divisions require static-tie, that slightly with a little force to plug not loose swing. Also, note the insulation plate center hole Center is better, not eccentric. F header pins on the back-end of the cable conductor casing to open 1 to 2 slots, not slotted (tubular) or on construction of four slots are inconvenient or difficult to clamp cable cable core (windproof lighter heating welding core wire inconvenience). Shell of insulating separators and joints should also be static-tie between, there should be no gaps that are too large. Some producers in three clearance above the cable connector type f is large, loosely arranged, and groggy, even eccentric centre hole clearly insulation plate, causing pin eccentric, to effect the electrical parameters, therefore these products should not be used.
3 waterproof, waterproof connectors cable feature to seriously test
Finally tighten the end inside the sleeve of waterproof joints typically place a waterproof apron about 10MM wide cable, when when the casing was gradually tightened, place a waterproof apron length position narrow, forcing the hole narrow the waterproof apron, tightly squeeze the outer sheath of the cable, in playing the role of waterproof. Some manufacturers of waterproof connectors when you tighten the sleeve, waterproof rubber ring inner diameter does not shrink into narrow enough, not a waterproof effect. So be sure to waterproof the cable test results as an extremely important quality control project, is simple: take a waterproof casing gradually tighten in joints by hand the last, being able to make waterproof cable rubber ring inside diameter reduced to about half its original size, thought the waterproof function of waterproof connectors can be. Connector cable for of course the best practical do to test confirmation. In addition, the waterproof quality of the apron is essential, quality waterproof leather apron is made of silicone rubber, usually rendered translucent, soft and easy compression, elastic, anti-aging and deteriorate.
