Description

The assemble method of computer connector and terminal construction thereof

The present invention be about a kind of assemble method of computer connector and with its terminal construction, refer to assemble method and and its terminal construction of used connector between a kind of disk drive and main frame especially.

Connector commonly used between general disk drive and motherboard as shown in Figure 6 and Figure 7, is respectively to assemble a terminal C by insulating base A two row's seat hole B to be constituted.Wherein, the structure of terminal C, be to establish fixed-wing F by the first contacting part D and the second contacting part E in central authorities to form so that sheet metal is die-cut, its transversal section all slightly is " U " shape, the U-shaped fixed-wing F of nationality central authorities is fixed in the seat hole B of insulating base A, its first contacting part D is stretched out from the insulation A first end face G, and the second contacting part E is hidden in the hole B.Aforementioned insulating base A commonly used is flat rectangle nylon block, and its first end face G is provided with the U-lag hole H that the first contacting part D of joint terminal C stretches out in the B of matching seat hole, stretches out the location in order to the terminal C first contacting part D of combination in the B of abutment hole.On the second end face J of insulating base A, there are two rows to be separated by and set equidistant square seat hole B, this square seat hole B extends internally, the fixing consubstantiality U-shaped seat K of fixed-wing F of terminal C is closed in establishing on hole wall, this U-shaped seat K is the extension of first end face (G) U-lag hole H and cooperate fixed-wing F to be pressed into, and uses for U-shaped fixed-wing F and is pressed into the location that is tightly fixed.When assembling, be the seat hole B that the first contacting part D of terminal C is aligned the insulating base A second end face J, and the U-shaped breach of fixed-wing F aligned U-shaped seat K, being pressed into U-shaped seat K by seat hole B makes the terminal C first contacting part D stretch out from the U-lag hole H of the first end face G, make fixed-wing F tightly fix U-shaped seat K location, the side finishes the assembling of a terminal C.Terminal C on a connector is generally 20, and when being assembled the utmost point one by one and taking a lot of work, and quality is restive.

Fundamental purpose of the present invention, promptly solve aforesaid difficulty, and a kind of assemble method of computer connector is being provided, each terminal second contacting part and the whole row of fixed-wing can be pressed into a hole positioning and fixing simultaneously, not only can save a large amount of assembling man-hour, can also improve the quality of products.

A time purpose of the present invention is to provide a kind of terminal construction of computer connector, makes this terminal when utilizing the method for claim 1 assembling, can increase and the friction tight friction force of connecting support, with the fixed effect of enhancement terminal.

The present invention seeks to realize like this: a kind of assemble method of computer connector, comprising: first step: a plurality of terminals that consubstantiality sheet metal band connected first contacting part, the every row's seat of the number of terminals coordinated insulation seat hole number that this is connected on the sheet metal band cuts into terminal row; Second step: the metal row folding above-mentioned with suitable anchor clamps positioning clamping is fixed in punch press, and adjusts the stroke of punch press drift; Third step: with insulating base first end face up, the location places under the drift, makes each slotted eye of first end face align second of aforementioned each terminal of terminal row and touches spots localization; The 4th step: the starting punch press makes drift to bottom offset, and with second contacting part and the fixed-wing of each terminal of terminal row, whole row is pressed into the location simultaneously from each slotted eye of insulating base first end face; The 5th step: excise the metal tape that terminal first contacting part connects simultaneously; Promptly finish the assembling of row's terminal, another row carries out in the same way.Two row's terminals can be assembled by two terminal rows simultaneously on this insulating base, with two terminal rows of anchor clamps positioning clamping.

Purpose of the present invention also can be realized by following measure, the terminal construction of described computer connector, include by the fixed-wing that is provided with between first contacting part and second contacting part and constituted, its transversal section is " U " shape, it is characterized in that two tip extension of this " U " shape fixed-wing are equipped with ratchet.

In sum, assemble method of the present invention is to be provided with the fixed-wing of chamfering with abutting end in the slotted eye with first contacting part of the first end face mating terminals of insulating base, and terminal connected into terminal row with metal tape, then with anchor clamps clamping terminal row, whole being pressed in the hole of terminal located with arranging, not only can save a large amount of assembling man-hours, and can control the quality of product.

Ratchet on the terminal fixed-wing among the present invention makes outside the fixed-wing and the close-fitting friction force of pedestal of terminal in addition, can also fix by ratchet, promotes the fixed effect of terminal.

The structure of number of assembling steps of the present invention and terminal with reference to the accompanying drawings, explains as follows:

Seeing also the bright connector of Fig. 1 to Fig. 41 is that a plurality of terminal 3 of insulating base 2 assemblings constitutes.Wherein, insulating base 2 is the nylon block of flat rectangle, and is illustrated in figures 1 and 2, and second end face 4 of this insulating base 2 is provided with in the square seat of two rows 5, one holes 5, hole that the setpoint distance of being separated by arranges and respectively assembles a terminal 3.On first end face 6 relative with it, shown in the 3rd figure, be provided with the slotted eye 7 that cooperates each hole 5, this slotted eye 7 has the fixed-wing 8 of chamfering and wringing fit terminal 3, and the extension suitable length forms connecting support 9 in seat hole 5, the fixed-wing 8 of nationality friction force fixed terminal 3, and make terminal 3 first contacting parts 10 protrude from first end face 6 of insulating base 2, and locate in the seat hole 5 that second contacting part 11 is hidden.This terminal 3 is to establish fixed-wing 8 by 10,11 of first and second contacting parts to be constituted, its transversal section all slightly is " U " shape, the lateral length of the both wings of U-shaped fixed-wing 8 is longer than first and second contacting

part

10,11, and its both ends respectively are provided with ratchet 12, in order to promote fixing friction force.

The present invention is when assembling, shown in the 5th figure, first step is to have consubstantiality sheet metal band 14 to connect a plurality of terminals 3 of first contacting part 10, this is connected in the spacing in 2 holes of spacing (Pitch) coordinated insulation seat of the terminal 3 on the sheet metal band 14, the quantity of its terminal 3 is the every rows' seat of coordinated insulation seat 2 holes 5 quantity also, and it is standby to cut into terminal row 13.Second step: be with first contacting part, 10 parts of terminal row 13 metal tapes 14 with terminal 3, be clamped on punch press (not showing on the figure) with suitable anchor clamps positioning clamping, and the stroke of adjustment drift, again up with insulating base 2 first end faces 6, the location places under the drift, make second contacting part 11 of terminal row 13 each terminal 3, align each slotted eye 7 location of insulating base 2 first end faces 6.The 4th step: the starting punch press makes drift to bottom offset, and with second contacting part 11 and fixed-wing 8 of terminal row 13 each

terminal

3,6 each slotted eye 7 whole row are pressed into the location simultaneously from insulating base 2 first end faces.The 5th step: excise the metal tape 14 that terminal 3 first contacting parts 10 connect simultaneously, promptly finish the assembling of row's terminal 3, another row carries out in the same way.

Two row's terminals 3 on the insulating base 2 of the present invention can also two-terminal row 13 be assembled simultaneously, and only two terminal rows 13 of anchor clamps positioning clamping make step identical.
