Abstract: A frame with an outer silicon layer and a manufacturing method of forming the silicone layer on the outer part of frame are disclosed. The manufacturing method includes a forming step, a combining step and a removing step. First, a pair of mold with a forming space is formed with a silicone carrier including an effective combination region and an ineffective region. An emplacing space is next formed in the effective combination region and a frame is put into the emplacing space. Before putting in the frame, either the outer part of frame or the emplacing space is coated with a silicone coating, and then the effective combination region is combined on the outer part of frame by a secondary sulfurization. Finally, the effective combination region is removed from the ineffective region to form a silicone layer, made of the effective combination region, on the outer part of frame.

Abstract: A micro speaker with amplitude stability, includes a vibrating diaphragm unit, a magnetic unit which is disposed below the vibrating diaphragm unit, and a circuit unit which is disposed between the vibrating diaphragm unit and the magnetic unit. The vibrating diaphragm unit includes a diaphragm which is connected with a voice coil; whereas the diaphragm and the voice coil are connected electrically by an upper fixing arm on the vibrating diaphragm unit, and a pair of flexible circuit board disposed in the circuit unit. The circuit unit also includes plural lower fixing arms to connect and support the flexible circuit boards. Therefore, when an external power source energizes the circuit unit, the voice coil can drive the diaphragm to generate a stable amplitude along the height of the magnetic element, through the upper fixing arm and the lower fixing arms.

Abstract: An injection molding method for a semifinished product includes a semifinished product emplacement step, a semifinished product pre-compression step and a forming step. First, a pair of mold with a forming space is provided. A semifinished product is put into the mold, and a first joint is performed to the mold by a press-fit jig, fixing the semifinished product in the forming space. The semifinished product is also tightly fitted with the mold. Next, a first open-die is performed and the press-fit jig is removed. After that, a second joint is performed, and a forming material is injected into the forming space. Finally, a second open-die is performed, and then a finished product is formed. By the semifinished product pre-compression step, the forming material can be prevented from resulting in spill or burr on the semifinished product, thereby improving the yield of injection molding.

Abstract: A light filtering assembly is installed in a lens module, including a fixed mount having a hollow part, a light filter at the hollow part, a shutter annularly disposed on the light filter, and a binding element. The hollow part is annularly formed by a support part extending from the fixed mount toward the hollow part. A first binding space is formed between the support part and the fixed mount, extending the outer periphery of the light filter and the shutter into the first binding space. An adhesive material is injected into the first binding space, and is then cooled down to form the binding element in the first binding space, so as to stop the light filter and the shutter at the hollow part as well as fix the light filter and the shutter on the fixed mount.

The insert face is dented inwardly so as to form a plug reception chamber in spatial communication with the terminal holes. A fixing element extends outwardly and downwardly from the insulated body. The fixing member is integrally formed with the mounting face of the insulated body via an injection molding process such that the fixing element of the insulated body is integrally formed with the fixing member. The terminals includes a row of terminals, each having an embed section embedded within the fixing member along an extension direction via an insert-molding process and a contact section projecting from one end of the front embed section through a respective one of the terminal holes and so as to be retained within the plug reception chamber in the insulated body.

Abstract: An electrical connector includes a positioning member; an insulated main body enclosing the positioning member from above and a plurality of terminals. Each terminal has a contact section embedded within a tongue plate of the insulated main body and an inclined section embedded partially within the positioning member via an insert-molding process. When the inclined section is further bent relative to the contact section, the uniform spacing and alignment among the terminals is maintained precisely due to the insert-molding process of the terminals in the insulated main body and the positioning member.

Abstract: An expendable electrical connector uses a plurality of modular housings sequentially assembled for receiving receptacle assemblies. The expendable electrical connector does not use dedicated moulds for different numbers of the receptacle assemblies and cost is decreased. Two neighboring modular housings share a side plate so that total length of the expendable electrical connector will be shortened and cost will also be decreased. Each of the modular housings may be made from a metallic sheet by punching process, and used to cover each of the receptacle assemblies and the modular housings can be connected with each other. The modular housings provide a good performance of grounding and shielding electromagnetic interference without dedicated grounding steps for individual receptacle assemblies.

Abstract: An electrical connector includes a mount plate and a metallic housing. The metallic housing includes a metallic frame and at least one hook-shaped rib which extend from the metallic frame and are used to hold the mount plate. The mount plate is made of low-cost material to replace expensive side tab extending from the metallic housing. Thus, size of mould for the metallic housing is decreased, scraps is fewer and cost is lowered.

Abstract: A card edge connector positioning apparatus has a first retaining trough, a second retaining trough and a support member. The first retaining trough is closer to a distal end of the positioning apparatus than the second retaining trough. The support member has a first edge and a second edge at two opposite sides. The first edge is wedged in the first retaining trough to form a movement fulcrum. The second edge is held in the second retaining trough to form a gap greater than that of the first edge in the first retaining trough. Thus the second edge has a greater displacement in the second retaining trough than that of the first edge in the first retaining trough. Thereby a displacement space for installation tolerance is formed for the support member.
