Terminal/hardware terminal customized professional stamping manufacturer

Terminal-a professional stamping manufacturer for hardware terminal customization 1. Terminal definition 1.1 A terminal is a product processed by a copper alloy through a high-speed continuous stamping die or a single engineering die. The terminal is the core part of the connector to complete the electrical connection function. 1.2 Generally, a contact pair is composed of a male contact piece and a female contact piece. The electrical connection is completed by the insertion of the female and male contact pieces. The male contact piece is a rigid part. 1.3 The positive contacts are generally made of brass and phosphor bronze. The female contact piece, the socket, is the key part of the contact pair. It relies on the elastic structure to be elastically deformed when it is inserted into the pin to generate elastic force and form close contact with the male contact piece to complete the connection. 2. Terminal shape 2.1 There are cylindrical, square, arc, cantilever, bifurcated, branched, male and female, shovel shape, guideline 2.2 reference pictures 3. Terminal materials 3.1 commonly used are phosphor bronze, red copper, bronze, Brass, beryllium copper, stainless steel and other metals 4. Technical characteristics of our company 4.1 Development of multi-cavity terminals: For example, DDR240P terminals are developed by ordinary companies only for 8 2X4, while the current 2X8 developed by our company is 16 and adopts mating connectors. Trial mold structure. Reducing the material width from 26.5mm to 21.0mm can save material by 17.5%, and the speed is increased from 500 to 650, which can fully save material and time cost for customers. 4.2 Development of small-step terminals: Generally, the terminal step distance developed by the company is more than 1.0, but the MINI-PCI step distance we developed is 0.60mm. This can save a lot of materials and greatly reduce the end product of the final product. This can make the product volume smaller and smaller and higher precision. 4.3 Development of multi-directional feeding terminal: Generally, the terminal developed by the company can only feed from left to right in one direction, but the HeaderPin terminal developed by our company is carried out from left to right and front to back at the same time, and the terminal after punching is convenient for gold plating , It used to be fully gold-plated, but now it can be changed to gold-plated contact ends, which can save more than 50% of the cost of gold-plating, and facilitate subsequent assembly, which can increase assembly efficiency by about 20%. 4.4 High-speed stamping: At present, our company's stamping speed can reach more than 1000 times per minute, that is, a 16-cavity mold can produce 12.5KK terminals a day. 4.5 The tolerance of the terminal is small: the tolerance of the general terminal is within +/-0.10MM, and some require tight tolerance control within +/-0.04, but our company can achieve +/-0.02MM. This tolerance is The mold requirements are very high. 4.6 Fish-eye shape rounding: This process is very complicated, and ordinary companies cannot complete the fish-eye shape rounding. We use computer-assisted equipment to edit the curve and use mirror discharge machining, and the surface requires polishing Ra0.40, and the product surface is round. The arc is very uniform. It will not scratch the PCB board. It is very beneficial to the use of the product. 4.7 Terminal twist 90 degrees: The terminal is twisted 90 degrees in the mold. This structure is very complicated and has a high degree of difficulty. We use the slider mechanism to form the terminal 90 degrees along the direction of the slider. This forming method is of quality relatively stable. 4.8 Multiple complex bending forming: This kind of process is very difficult in the connector industry. We use double strips to send to the mold and use the mechanism to connect one terminal to the other terminal. 4.9 Punching thin materials: The thickness of the materials processed by the general company is 0.15mm to 0.50mm, but our company can process materials with a minimum thickness of 0.08mm. The processing accuracy of the processing of this thin material mold is one level higher than usual .4.10 Punching thicker and harder materials: Generally, thicker and harder materials will easily wear the punch and knife edge, so we use better mold steel, which can process materials with a material thickness of 0.8 or more. 4.11 Good section Smoothness: For the connector, the better the smoothness of the contact surface, the smaller the impedance, the smaller the surface wear, the more durable the product, and the more stable the transmission signal. The surface bright band of the terminals we produce reaches more than 95%. 4.12 The width of the punch is less than the thickness of the material: When the width of the punch is less than the thickness of a material, the punch is very easy to break. In this case, we have a wealth of solutions. 4.13 Small terminal burr control: Generally, the terminal burr is controlled within 0.04MM, but the terminals produced by our company can be controlled within 0.02, so that it will not be scratched between the plastic and the terminal during assembly and the gold-plated surface will not be scratched. , Conducive to the stability of conductivity. 5.
