Abstract: This disclosure relates to a piercing-type motor terminal connector, comprising a main body with a board end and a wiring end which are facing away from each other. The board end is disposed with pins for board connection, while the wiring end comprises a first elastic arm and a second elastic arm aligned side by side. A main clamping groove is formed between these arms, capable of establishing adjustable tension state based on the elasticity of the first arm and the second arm. At the groove entrance of the main clamping groove, serrations are disposed on the first and the second elastic arms. The serrations are used to press and pierce the enamel of enameled wire, allowing the wire to slide into the main clamping groove and be held by the first and the second elastic arms, thereby forming an electrical connection. Additionally, a force-enhancing part is disposed on both the first and second elastic arms, which increase the clamping force when the enameled wire enters the main clamping groove.

Abstract: This disclosure pertaining to the technical field of electrical connector structures, specifically relates to an electrical connector structure of a fish-eye terminal. It comprises an insertion part and a connecting part, with the insertion part further comprising a guiding section, an inserting section, and a connecting section. The guiding section is flat and arc-shaped, and the insertion part is connected to the connecting part through the connecting section to form an integral whole. The guiding section, inserting section, and connecting section are integrally formed, presenting a shuttle-like structure with two smaller ends and a larger middle. The lower part of the inserting section is integrally formed with its both ends connecting to the guiding section and the connecting section respectively. The upper part of the inserting section is olive-shaped and disposed with a groove, with an enhanced edge disposed on the outer side of the groove.

Abstract: This disclosure relates to a novel motor terminal connector. The main body comprises aboard end and a wiring end, the board end is disposed with a pin, and the wiring end is disposed with a receiving slot; the receiving slot has an opening away from the pin, and on both sides of the opening, two elastic cantilevers are disposed, with the free ends of the two elastic cantilevers extending towards the inner bottom of the receiving slot, leaving a gap with the inner bottom, and the free ends of the two elastic cantilevers gradually approach each other as they extend; the two elastic cantilevers are used to clamp enameled wire, and serrations are disposed on the opposing sides of the two elastic cantilevers, where the serrations are used to press and pierce the enamel of the enameled wire, thereby enabling the two elastic cantilevers to clamp the enameled wire and form an electrical conductive connection.

Abstract: A 3D printing method is provided. A stereolithography 3D printer (2) selects one of multiple layers of print data sequentially, makes a modeling plane be a default thickness (h) away from a material tank (23), irradiates heading to the modeling plane according to the selected layer of the print data for printing one layer of slice physical model (421-422, 431-433), makes the modeling plane detach from light-curable materials (41) in the material tank (23), rotates the material tank (23) for making an angle difference between angles before and after rotation be within a default angle interval, and performs above steps repeatedly until completion of a 3D physical model.

Abstract: A 3D printing device including a base, a gantry, a forming platform, a tank, an adjustable platform, a driving module and a control module is provided. The gantry and the tank are respectively disposed on the base. The forming platform is movably assembled to the gantry. The adjusting platform is disposed between the gantry and the forming platform or between the tank and the base. The driving module is connected to the forming platform and the gantry. The control module is electrically connected to the driving module to drive the forming platform to reciprocate along the gantry, so that the forming platform is moved into or out of the tank. Before 3D printing is performed, the control module moves the forming platform to lean against the tank through the driving module, so as to drive the adjustable platform to deform, and confirm consistency of contact surfaces of the forming platform and the tank.

Abstract: A formation tank includes a tank body and a release film. The tank body includes a bottom plate and a tank wall. One face of the bottom plate is an inner bottom surface, and at least one engagement structure is formed on the inner bottom surface. The tank wall protrudes from the inner bottom surface and surrounds a periphery of the bottom plate. The release film is attached on the inner bottom surface and the release film is mortise-and-tenon connected to the engagement structure. An engagement structure is arranged on the bottom plate to improve an engagement force between the bottom plate and the release film. Accordingly, the release film is prevented from being detached, and therefore durability of the release film is also improved.

Abstract: A 3D printer including a machine platform, a container and an injection module is provided. The container and the injection module are disposed on the machine platform, and the injection module injects a liquid forming material into the container. The injection module includes a bottle body, a deformable opening member, a driving assembly and a flow guide member. The bottle body contains the liquid forming material. The driving assembly is adapted to deform the deformable opening member. The driving assembly drives the deformable opening member to an open state, and the liquid forming material in the bottle body flows to the flow guide member through the deformable opening member, and flows to the container through the flow guide member. The driving assembly drives the deformable opening member to a close state, and the liquid forming material stops flowing to the flow guide member from the deformable opening member.

Abstract: A method for forming an integrated circuit having Micro-electromechanical Systems (MEMS) includes forming at least two recesses into a first layer, forming at least two recesses into a second layer, the at least two recesses of the second layer being complementary to the recesses of the first layer. An intermediate layer is bonded onto the second layer, the intermediate layer includes through-holes corresponding to the recesses of the second layer. The first layer is bonded to the intermediate layer such that cavities are formed, the cavities to act as operating environments for MEMS devices. The two cavities have different pressures.
