Embodiment
The present invention is further described below in conjunction with drawings and Examples.
The present invention includes but be not limited only to following embodiment.
In order to overcome the deficiencies in the prior art, the present invention at first needs to determine problem:
A), the position of PCB during crimping, that is: PCB is horizontal positioned or vertically places;
B), which face with socket is datum level during crimping;
C), which kind of material is frock select for use;
D), use which kind of pressure apparatus;
To problem determining a): if PCB is with horizontal positioned during crimping, crimping face namely is locating surface, can't guarantee the crimping effect;
To problem b) determine: according to the relative position after printed board and the socket crimping, should vertically place with PCB during crimping, with perpendicular that face of the face at CPCI socket pins place be benchmark;
To problem c) determine: make frock with aluminum alloy materials, low because of the aluminum alloy materials price, processability good, material is soft; Nonmetal material system is more crisp, when size hour insufficient strength, is not durable;
To problem d) determine: the last components and parts assembling of PCB belongs to meticulous assembling, on the PCB any pollution and distortion can not be arranged after the assembling; As passing through the frock crimping with electronic or pneumatic press, because pressure is big, bad control; Most importantly electronic or the Pneumatic pressure motor speed is fast, socket pins has crooked in preservation, transportation, installation process slightly, printed board metallization installing hole does not have enough time to force socket pins generation strain during crimping, pincard is outside printed board metallization installing hole, be clipped at last between printed board and the socket plastic body, cause socket to be scrapped, and the dismounting of crimping socket after scrapping is very difficult.Therefore selecting flat-nose pliers for use is compression bonding apparatus.
According to above-mentioned requirements, drafted two kinds of frock schemes:
1) rectangle cellular type
2) broach shape formula
The rectangle cellular type is to open a rectangular opening at an aluminium sheet, and the aluminium sheet pad exposes the PCB side (solder side of PCB) in socket pins during crimping operation.Because rectangular opening size on the plate has comprised the socket pins matrix, socket is pressed onto the position, and pin can not interfere with frock after exposing PCB.The shortcoming of rectangle cellular type is that the long limit size in hole is big, may make the PCB distortion after the crimping, even printed board is indeformable, can leave a trace at printing board surface in the edge in hole, and can't operate when the 2nd socket of crimping.If the long limit size of rectangular opening is increased to the width of PCB, though solved the crimping of adjacent outlet, the PCB distortion can be bigger, so this scheme is infeasible.
For solving above-mentioned contradiction, according to the socket pins queueing discipline, intend with broach shape formula structure.As long as each size design of broach, calculating are accurately, the gap is suitable, and clips printed board and socket crimping with two part surface opposites, to solve the PCB distortion, and frock broach length is the twice of socket pins row size, has also solved the continuous crimping problem of adjacent outlet.
As shown in Figure 3, the present invention includes broach shape structural member and location half the circumference of the sleeve where it joins the shoulder spare, described location half the circumference of the sleeve where it joins the shoulder spare is a rectangular block, and rectangular block one side is step surface, and the height of the part that step surface thickness is little has the width of pin one side greater than the CPCI socket; Described broach shape structural member is a rectangular block, at rectangular block one lateral process some row's broach is arranged, and when the CPCI socket being holded up on the step surface that is placed on location half the circumference of the sleeve where it joins the shoulder spare, each arranges the gap of broach over against each row pin of CPCI socket.
The equal rounding of each broach front end on the described broach shape structural member.
The material of described broach shape structural member and location half the circumference of the sleeve where it joins the shoulder spare is the hard rustproof aluminum alloy.
CPCI socket mounting hole position on the printed panel and the pin of CPCI socket are to thereafter, and described broach shape structural member and location half the circumference of the sleeve where it joins the shoulder spare drive by flat-nose pliers and close up, and the crimping of CPCI socket is put in place.
Half the circumference of the sleeve where it joins the shoulder with location half the circumference of the sleeve where it joins the shoulder spare during crimping is datum level.Printed board is vertically placed during crimping, and broach shape structural member places the printed board solder side, and location half the circumference of the sleeve where it joins the shoulder spare places the printed board installed surface.
The size of broach shape frock most critical is: the half the circumference of the sleeve where it joins the shoulder face of location half the circumference of the sleeve where it joins the shoulder spare is to the distance of CPCI socket the 1st row pin, and spacing, the broach thickness of each broach of broach shape structural member, they have determined whether the frock broach interferes with the CPCI socket pins that sees through the printed board installing hole in implementing the crimping process.And the half the circumference of the sleeve where it joins the shoulder face of location half the circumference of the sleeve where it joins the shoulder spare is relevant with the broach position on the broach shape structural member to the distance X of CPCI socket the 1st row pin.Measure, to calculate required size accurate, each row pin of CPCI socket passes in the broach groove that the PCB pin bores enters the broach frock after the crimping, this is best result.
If measure, calculate or be processed with deviation, will cause each row pin of CPCI socket just to pass the PCB pin bores after the crimping, just interfere with the frock broach, cause the CPCI socket to be scrapped.Therefore, the first step at first accurately measures the related size X of CPCI socket.
Measure CPCI socket datum level to the first row pin apart from the difficulty maximum, because of they not at grade, one is that face, one are a little, can only observe repeatedly, measure by face plate.This size belongs to bulk.Be put on the face plate with CPCI socket datum level during measurement, adjust the vernier of marking-out rule up and down, make the chi point of marking-out rule aim at CPCI socket pins point, cause is tip to tip, need examine at horizontal plane, repeated measurement, finally obtain this size, accurately design the frock drawing.
Drawn by related size X: the size 16.8 in the broach shape structural member is the shoulder height size with the size 5(that locatees in the half the circumference of the sleeve where it joins the shoulder spare) be correspondingly-sized.Broach thickness 1.2mm in the broach shape structural member, broach gap 0.8mm, broach height 3mm.Regulation in relevant national military standard (GJB) and the aerospace standard (QJ): the components and parts pin height that the printed board solder side exposes is 1mm～2mm, so broach height 3mm is enough.
Use the high-precise numerically controlled milling machine processing tool, guarantee that machining accuracy satisfies the drawing requirement.Each broach is handled through meticulous rounding on the part 1.
Rely on broach shape structural member and location half the circumference of the sleeve where it joins the shoulder spare related size accurately, guarantee to implement in the crimping process frock broach and can not interfere with the socket pins through the printed board installing hole and damage the CPCI socket.
One side with the CPCI socket during crimping is located with the step bottom surface of frock, and the swivel vice screw rod is implemented crimping.Because frock broach size design is more accurate, needn't worry that the broach of frock can withstand the contact pin of CPCI socket and stop midway to check that the crimping process is accomplished without any letup.
The Manual pressure device is flat-nose pliers, because flat-nose pliers has dovetail groove, and the precision height.Before the crimping, be positioned on the flat-nose pliers by two parts frock shown in Figure 4, by the mounting hole site of CPCI socket in the printed board CPCI socket be preloaded onto in the printed board, this moment, the tip portion of CPCI socket pins front inserted in the printed board installing hole.Printed board is vertically placed, make CPCI socket datum level just contact, set level, put with the half the circumference of the sleeve where it joins the shoulder of location half the circumference of the sleeve where it joins the shoulder spare with the CPCI socket, manually swivel vice screw rod to broach shape structural member, the location half the circumference of the sleeve where it joins the shoulder spare of frock contacts with printed board and CPCI socket respectively, use leverage tool swivel vice screw rod then, be pressed onto the position until the CPCI socket.
