A electrical contact, which is secured in a slot of a housing used to electrically connect a printed circuit board with a chip module comprises a tail portion mounted on the printed circuit board, a contact portion with a torsion portion based on the axis of the slot of the housing at least partly extending out of the slot contacting to the chip module and a base portion connected the tail portion with the contact portion. Thus, the space between the adjacent contacts will be improved to avoid the short circuit. Furthermore, even if the contacts are secured imprecisely, there will not be apt to form a short circuit between the adjacent contacts.

An electrical connector can be provided in which the operations of the sensing means and locking means are linked, so that mating and locking of the connector parts are reliable. An electrical connector comprises a first connector part that has a male housing with an engaging portion; a second connector part that has a female housing provided with a cavity; a sensing means that senses the two parts; and a locking means that locks the mated state is made of a clip member having first latch portions, and a second latch portion. The sensing means is made of a sliding sensing member having a sensing arm provided with an engaging portion. A through-hole is formed on the female housing. The spring wire-like body of the clip member is mounted onto the surface of this outer wall, and the sliding sensing member is fitted also onto the surface of the outer wall slidably in the direction of mating with the male housing, so that with the first and second connector parts mated the first latch portions of the clip member engage with the engaging portion of the male housing, and the engaging portion of the sliding sensing member latches into the second latch portion of the clip member.

The invention discloses a center floating type chuck. The center floating type chuck comprises a chuck body, a locating unit, a floating clamp unit and a connecting unit. A center hole is formed in the chuck body. The locating unit is matched in the center hole and used for locating centers of workpieces. The floating clamp unit is arranged on the chuck body and comprises a plurality of high jaws capable of carrying out asynchronous movement so as to clamp the workpieces whose centers are located on the locating unit. The connecting unit is respectively connected with the floating clamp unit and a drive device which is used for driving the floating clamp unit. The center floating type chuck has the advantages of clamping the workpieces, reducing locating errors of multiple clamps and the like under the condition of being capable of locating the workpiece centers.

A combustion-engined setting tool for driving fastening elements such as, e.g., nails, bolts, or pins in a workpiece, includes a plate-shaped member (17) axially displaceable in the tool combustion chamber (14), a member (33) for displacing the plate-shaped member (17), a holding device (30) for retaining the plate-shaped member (17) at an axial end (15) of the combustion chamber (14) against action of the displacing member (33), with the holding device (30) having magnetic elements (31) for producing a holding force for retaining the plate-shaped member (17) and a device for overpowering the holding force produced by the magnetic elements (31).

The invention discloses a detachable connecting device. The detachable connecting device comprises a fixing table, a base table and a sliding block, wherein the fixing table is fixedly connected with a first component, the base table is fixedly connected with a second component, and the sliding block is matched with the fixing table in a sliding mode. The base table is matched with the fixing table in a sliding mode, matched assemblies are arranged on the base table and the fixing table, the assemblies are used for making the sliding block slide in place relative to the fixing table and then locked and making the base table and the fixing table matched in a sliding mode and then locked, and the assemblies can make the sliding block slide relative to the fixing table and finally make the sliding block and the fixing table separated and unlocked. The invention further provides a connecting device of a wire harness connector and a buckle. The connecting device of the wire harness connector and the buckle is compact in structure, small in size, smooth in matching, firm in fixation, easy to detach and install and capable of being reused for a long time. The connecting device can be used as an intermediate connecting part for connecting two components such as the vehicle wire harness connector and the buckle.

The invention relates to a pressure gauge. The pressure gauge comprises a gauge case, a dial, pointers and a switching structure, wherein an introduction hole is formed in the bottom of the gauge case. The pressure gauge is characterized in that the switching structure comprises a transmission rod, a transmission base and a supporting spring, the transmission rod is axially restrained in the gauge case and can rotate around the axis of the transmission rod, external transmission threads are arranged on the transmission rod, and the pointers are fixed to the upper end of the transmission rod; the transmission base is arranged in the gauge case and can move vertically, the transmission base can move upwards under the driving of air pressure, a guiding hole is formed in the transmission base, the transmission rod is arranged in the guiding hole in a penetrating mode, and the hole wall of the guiding hole is provided with internal transmission threads matched with the external transmission threads; the supporting spring acts on the transmission base so that the transmission base can keep the tendency of moving downwards. The switching structure in the pressure gauge is simple and reasonable and good in transmission stability because of thread fit transmission, the pressure gauge is good in anti-shock effect, no complicated lever structure or gear structure is needed, and therefore the pressure gauge can be manufactured to be very small, all the parts are simple in structure, the cooperative relation between the parts is little, and cost is greatly reduced.

The invention provides a blade tenon tooth positioning device. The tenon tooth positioning device comprises a base and a plurality of blocking teeth which are arranged on the base at intervals, wherein a first positioning inclined surface and a second positioning inclined surface which are oppositely arranged are respectively arranged on the adjacent first blocking tooth and the second blocking tooth; and an included angle between the first positioning inclined surface and the second positioning inclined surface is matched with a tooth-shaped angle of a to-be-positioned blade tenon tooth. According to the technical scheme adopted by the invention is applied, the blade tenon tooth positioning device can be used for realizing reliable matching between the plurality of the blocking teeth and the blade tenon tooth, good in stability, and has relatively good measuring precision.
