(1) the pluggable terminals: LC LZ Series supporting the use of LC plugs, LZ-the socket;

LC Series:

Lc1:90 degrees angle design; LC2: is divided into a,, and b two small class, window and card angle direction consistent for a,, instead is for B;LC3:180 ° angle design; lc4:45 degrees angle design, common application Yu following electrical protection and the automation industry; LC5:180 degrees angle design, for instrument industry; lc6: and LC3 phase similar; lc7:90 degrees angle design; lc8:180 degrees angle design; LC9: double into line structure; lc10: Can composition wear Wall Terminal mutual supporting using (cases: LZ5X,lc1); lc11: and lc10 similar, difference is the series used spring type into line; LC12: and called Board on board wiring Terminal, without wire connection; lc13: two into a out; lc14:LC1 upgrade version, performance and LC system, increased screws solid positioning; lc15: tie guide using; LC16, and lc17, and lc18, and lc19:U type design; lc20: anti-wrong plug design, Ensure the rigour of product use.

LC Series frequently asked questions:

Slide 1 and screws: easily lead to temperature increases over current, which pushes the screws slide;

2, the use of environment accidents can cause Terminal materials aging;

3, LC series of fuzzy concepts a and b;

4, plating layer: clip galvanised material choices directly affect the performance of the connection, conventional nickel plated or gold plated, silver, can effectively increase the efficiency of signal transmission

LZ Series:

Products are divided into a straight pin (v), bent (r); open (k), close (); ear (m)

Lz1 series: single-row design; lz2:45 degrees; the lz3: double: parallel (h) and double (t) lz4: vertically with the PCB Board; mainly used in instrument industry; the LZ5: through-wall Terminal (example: lz5x, lc10 and LC1); LZ6: use with the LC1, mainly for the wire and cable industry.

LZ Series frequently asked questions:

1, solid welding stitch: industry standards: 4N

2, curvature: bent in the product greater than 12P be considered, either due to a crisp or softer material raw material;

3, electroplating questions: main materials for Tin, cons: subject to time restrictions;

Common types of Tin in the industry: Tin Tin, mists (also known as stannous), tin coating determines the ability of the product to the amount of soldering;

4, color: choose not to plain material.

 

(2) direct-weld terminal blocks: can be divided into rectangular, bevel angle (90 °, 135 °); products can be divided into single, double, three-layer

Characteristics: small value, amount, less profit;

Model: common model consistent with the industry, to market them;

Products: mainly for product sizes are inconsistent.

 

(3) the spring Terminal: can be divided into direct-weld, plug type series can also be divided into ridges and overlapping. Commonly used in lighting, security industry, CQC certification requirements. Its main features are: 1, dominated by stitching 2, high cost of assembling;

Spring-loaded Terminal frequently asked questions:

1, the plug-in is not enough: on the one hand from the die itself originates from, on the other hand involves the use of Thermo-contact force does not meet the requirements.

2, lack of tension: use materials selection is not reasonable

Other products: LSC1 series, mainly used in the elevator industry, rail industry.

 

(4) the barrier  Terminal: also known as American, Japanese-style terminals within the industry, most important feature connection terminals for intuitive and disadvantages for the spacing is too large, use the first Terminal used. Routine use of material for PBT.

Product classification

LW1: the side openings

LW2: plus cover

LW3: opening above + backrest

LW4: cover + back

LW5-Groove design

LW6: double-layer design

LW7: pluggable spring terminal block

Barrier type Terminal frequently asked questions:

1, slide wire: possible causes: lack of quality assurance systems use inferior raw material

2, plastic fracture: the proportion of ingredients in the production process are not scientific

3, electroplating questions: electroplating material selection is not reasonable
