Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A kind of CPCI socket of the utility model welding equipment positioning and locking device, as shown in Figure 1, comprises positioning component, handle 2, and pressing plate 3, latch assembly 4, to plug-and-socket assembly 5; Positioning component comprises that two bottoms extend to a side 1, two locating piece 1 of locating piece be provided with step and be step and be oppositely arranged, and the top of locating piece is symmetrically arranged with fastening stud 6; Fastening stud 6 is threaded with handle 2 through pressing plate 3; As shown in Figure 2, the latch assembly 4 that is arranged on pressing plate 3 belows comprises can sealed fixing front gusset 401 and rear gusset 402; To plug-and-socket assembly 5 comprise with the same row of CPCI socket or with a line, coordinate some to plug-and-socket, front gusset 401 and rear gusset 402 are for fixing to plug-and-socket assembly 5 from sandwich.

Wherein, the step width on locating piece 1 is 4-6mm, and in this preferred embodiment, adopting the wide step of 5mm is that example describes; Handle 2 is concave shape setting, in the groove in the middle of fastening stud 6 is connected to; Line direction along fastening stud 6 on pressing plate 3 is provided with gathering sill; As shown in Figure 2, front gusset 401 and rear gusset 402 are by being separately positioned on sealed the fixing of lock-screw 7 of both sides.Not only positioning precision is high for it, affected easy, can multiple CPCI receptacle combinations be realized and being reused, and in positioning and locking process, CPCI socket zero be damaged.

During use, as shown in Figure 3, in printed board 9, install after the CPCI socket 8 of locking to be positioned, what selection coordinated with a line or same row with it is arranged in order rear formation to plug-and-socket assembly 5 to plug-and-socket, and with front gusset 401, rear gusset 402 by above-mentioned plug-and-socket assembly 5 is locked from sandwich is fixing, and with printed board 8 on CPCI socket to be positioned realize inserting, and pressing plate 3 is pressed on latch assembly 4, realize locking positioning.The centre of pressing plate 3 has gathering sill, locating piece 1 is connected with handle 2 use fastening studs 6, locating piece 1 is connected with fastening stud 6 rubber seals, in gathering sill, realize the slip of fastening stud 6, by the rotation of handle 2 is realized to pressurization by 3 pairs of latch assemblies of pressing plate 4, guarantee plug-and-socket assembly 5 to be connected with CPCI socket 8 and the reliable of printed board 9.The width that locating piece 1 is topped bar coordinates with the width of technique edges in printed board 8, in the present embodiment, take 5mm as example, locating piece 1 is hooked to technique in printed board 8 to be added and holds on limit, both realized positioning and locking function, can not cause damage to other device in printed board again, realize the CPCI socket positioning and locking for the treatment of welding equipment.For different CPCI receptacle combinations, only need carry out corresponding adjustment to plug-and-socket is put in order can realize of the present utility model reusing, and treats CPCI socket zero damage of welding equipment.By 3 pairs of pressing plates, contact with latch assembly 4 and compress design, not only considered the uniform pressure distribution of latch assembly 4, the interference having occurred while having avoided again front and rear row CPCI socket to install, and butt welding point is unobstructed can not shelter fifth wheel, guarantee can butt welding point to test in the situation that device is not dismantled.For the printed board of different in width, can coordinate plug-and-socket assembly 5 by changing the latch assembly 4 of different length, realize the covering of installation situation in the printed board of different CPCI socket.Not only realize accurate location when CPCI socket is installed, and due to its combination in any, greatly improved the reusability of this device, reduced use cost, improved production efficiency, and easy and simple to handle, safeguard that necessity is low.
