The advantages and features of the utility model will be easier to understand for the technicians in the field, so that the scope of protection of the utility model can be more clearly defined.

Example embodiments 1

As in the Shown is a 90 degree socket base for electrical connectors of this type, including a connector housing 1 . At the top of the connector housing 1 an opening is provided and a top cover is attached to the opening 1-1 the socket base which can be rotated up and down. Mortise 1-1b . The above mortise 1-1b has a sealing round hole on one side and a half-open round hole on the other side. The spindle 1-1a is after the installation of the spindle 1-la by the downward pressure of the upper nut seat cover 1-1 not flung out so that the upper nut seat cover 1-1 easily around the spindle 1-1a can be opened and closed around. In this embodiment, the top cover flip angle is the female socket 1-1 90 degrees. In the connector housing 1 is an insertion slot for inserting a direct print insert 2 provided, and at the bottom of the connector housing 1 is a removable card plate 1-2 provided (the electrical connector nut base is a shielded nut base). As in 3 shown, the above-mentioned cardboard can 1-2 be of a fixed type, in which case the electrical connector socket seat is an unshielded socket seat. At the end of the connector housing 1 there is a card slot 1-3 according to the map block 712 on the wire snap-on base 71 for attaching the wire snap socket 71 on the connector housing 1 . On the inside of the lid 1-1 the die base has a bevel 1-1c that is used in conjunction with a subsequent beading slope.

In combination with and can be seen that when the cardboard 1-2 removable on the underside of the connector housing 1 is mounted, a hook slot 1-5 on the connector housing 1 is provided to ensure the stability of its installation. The hook slot 1-5 is with a limited fixed snap post 1-6 The pluggable part of the cardboard 1-2 has a fixed slide 1-2a , and in the said fixed slide 1-2a there is a limiting hook on the mouth 1-2b , the lining slipping out 1-2 from the connector housing 1 prevented and the feed 1-2 completely on the connector housing 1 fixed so that it is when inserting the boundary retaining post 1-6 into the fixed sliding slot 1-2a through the boundary hook 1-2b does not fall away from the external force. The mouth of the fixed sliding groove 1-2a for the convenience of the limited fixed card column slides into the figure-eight rail 1-2c .

Said connector housing 1 is with a direct pressure connector 2 , a printed circuit board 3 , a connection block 4th , a wire tie cover 5 and a cable manager 7th fitted. The front of the circuit board 3 is with a first set of fasteners on the direct pressure connector 2 connected. On the back of the circuit board 3 there is a second set of connection elements 6th that come with the terminal block 4th are connected. The wire binding cover 5 is with the connector housing 1 latched and at the end of the wire binding cover 5 is a cable manager 7th intended.

As in shown, contains the insert 2 of the direct press type a pin mounting bracket 21 , two pin mounting bracket clips 23 , 24 , two rows of pens 22a , 22b . the pin mounting bracket 21 contains a moving support point curved like a net 25th , the pin mounting bracket 21 opens eight pen slots 26th . the first row of pins 22a and the end of the second row of pins 22b are each in the pin slots 26th inserted so that the pins don't swing left and right. The pin mounting bracket 21 and the two mounting bracket clips 23 and 24 snap together by their own mechanical structures, making the first row of pins 22a and the second row of pins 22b can be mounted more stable. In particular, there is a positioning slot A on the pin assembly bracket 21 for placing the first row of pins 22a intended. Support pillars are provided on either side of the positioning slot A, and vertical slots are provided on the opposite sides of the two support pillars. The first component holder Snap 23 is inserted into the vertical slot first. A positioning slot B is on the top of the first component retainer snap 23 for placing the second row of pegs 22b intended. The aforementioned positioning slots A and B are staggered in order to avoid the first row of pins 22a and the second row of pins 22b overlap each other. The curved part between the two ends of the first row of pins 22a and the second row of pens 22b withstands the mesh-like curved movable support point 25th so that the first row of pins 22a , the second row of pens 22b is not deformed after the force. This increases the elasticity and performance of the first row of pins 22a and the second row of pins 22b . Even if one of the pins is under pressure, the other seven pins that are in normal contact with the plug of the electrical connector will not be affected, thereby avoiding the poor contact caused by plugging in the connector. The ends of the first row of pins 22a and the second row of pens 22b all have fish-eye shaped through holes so that when connecting to the circuit board 3 no welding process is required. Not only does this reduce production difficulties and costs, but it also solves the problem of poor contact caused by problems such as solder leakage and incorrect solder from the root. Increase the service life. The first row of pins mentioned above 22a , second row of pens 22b are collectively referred to as the first group of connecting elements.

The connection block 4th is with a card line slot 4-1 corresponding to the second group of connection elements 6th and is symmetrical on both sides of the connection block 4th distributed. In this example, the number of the first group of fasteners is the same as the second group of fasteners 6th eight, the number of cable ducts 4-1 also eight and four on the terminal strip 4th symmetrically distributed four above and four below. The wave base plate 4-2 is equipped with a slot in the wiring cover 5 can be pushed in and the press fit 4th on the side of the lid 5 fixed. Under the shaft base plate 4-2 A circular recess is provided leading to a small column at the front of the snap wire base 52 fits.

In combination with the and it is clear that the wire punch cover 5 (ie the wire stowage device of the patent) a wire punch housing 51 contains. The wire punch housing 51 has a hole 53 that extends from the back to the front to pass the cable through. The wire punch housing 51 has a pinch slope 52 on the front for squeezing. The snap wire assemblies are symmetrical along the top and bottom of the holes 53 distributed on the wire punch housing. How out can be seen, it is the pinch bevel 52 curved pinch edges symmetrically distributed around a pair of left and right. In particular, the left and right outer surfaces of the wire wrap housing are 51 with a finite slot 59 Mistake. The distance between the finite slot 59 and the top surface of the wire wrap housing 51 is longer or shorter than the distance between the finite slot and the bottom surface of the wire lay housing (ie, the finite slot 59 is not in the center of the wire wrap housing 51 distributed). The wire binding case is not mounted in the correct position for the timing slot to be inserted, thereby preventing the wire binding device from being improperly installed.

How out As can be seen, each group of the wire binding assembly includes an outer first side wall 58 and an inner second side wall 54 . The first side wall 58 , the second side wall 54 and the wire binding case 51 are close together and form a tangent slot 55 . The first side wall 58 is with four semi-closed grooves 56 Mistake. The type groove 57 is set accordingly. The semi-closed groove jam can effectively block the signal crosstalk between the cable groups and improve the efficiency of the signal transmission. A frame is provided on the outer surface of the first side wall to identify the color of the cables to make it easier to install the cables in the correct order.

Of course, as in shown, the crimp bevel 52 on the above mentioned wire wrap cover 5 can also be designed as a curved crimp edge rounded on four sides. Four weeks of rounded crimp edge can be crimped left and right or up and down for easier crimping of wire that meets the shell.

This technical solution uses a card assembly evenly distributed along the perimeter of the hole on the wired housing to lock into the appropriate cable group, effectively blocking the signal crosstalk between the group and the group and improving the efficiency of the signal transmission. Due to the pinch angle, the crimping increases the tightness of the cable set and the electrical connector base connection and reduces the signal attenuation to ensure the quality of the signal transmission.

A cable manager 7th is on the outside of the wire wrap cover 5 provided to cover the cables that are in the wire wrap 5 enter, protect. Combined with contains the cable manager 7th a cable clamp 73 , a cable clamp base 71 and a cable tray cover 72 . The cable clamp base 71 is with a tub 711 provided on which the wire wrap cover 5 and on both sides of the tub 711 there are tabs 712 that are on the connector housing 1 snap open. The lid 72 closes and forms the said map line channel. The rear wire cover 72 is above the wire gate 73 arranged. One end of the wire snap 73 is at a first end of the wire gate base 71 hinged. The other end of the snap wire clip 73 snaps onto the second end of the snap wire base 71 . Like from BILD 5 can be seen, is that second end of the snap cable base 71 with a spring slide 715 provided, which is provided with a striped snap point. The wire snap socket 71 is at the first end of the snap socket 71 with a wire snap retention pin 714 Mistake. The wire snapper 73 is circular, with one end of the snap 731 with the wire gate retaining pin 714 and the other end of the snap 733 with the shrapnel pusher 715 is articulated. The toothed shrapnel 733 is at the bottom of the serrated shrapnel 733 curved and hollowed out and with a curved spring clip 734 on the outside of the serrated shrapnel 733 Mistake. the clamp 734 fits the strip tabs and locks the other end of the wire clip into the shrapnel slide 715 a. A finite point 735 at the end of the serrated shrapnel 733 prevents the bottom of the serrated shrapnel slide 733 . The snap-snap 73 is with a fixed mounting point 732 which allows easy gripping of the part by hand and easy installation and removal. The fixed post with a push button 73 is on the push button base 71 mounted, and the cable is installed by simply inserting the cable into the cable retention slot 713 is placed. The cover of the manhole cover 72 is covered to the cord with the push button 73 secure so that the cable does not wobble, which leads to poor contact at the front contact point and ensures the stability of the data transmission.

After the cable is installed in the cable manager, it is first electrically connected to the end of the second set of connectors on the terminal block, and then the signal is transmitted to the circuit board and through the circuit board to the first set of connectors and finally to the external device plugged into the electrical connector socket. Of course, when it is necessary to read the data on the external device, the data on the external device is sequentially transmitted to the cable through the first set of connectors, the circuit board and the second set of connectors.

The male end of the connector housing 1 has a dust flap that can be folded inwards 8th Mistake. The specific design: At the plug-in end of the connector housing 1 a dust master seat is provided. The dustproof female seat includes a dustproof door, a spring, and a female seat body. The dustproof door is equipped with two card slots and two mounting blocks for electrical connectors. The female body is provided with a closed dust window, two card posts on the top of the inside of the window and a direct pressure connector lip and female bottom cover on the bottom of the window. The combination of the closed dust window, the spring and the dust door of the female body effectively protects the direct pressure connector and extends its service life. When the plug of the electrical connector is connected to the dust master because the dust master has a closed dust window, it can effectively fix the plug of the electrical connector and ensure the contact between the plug of the electrical connector and the inline insert and normal and effective data transmission under the most extreme conditions. When the connector is pulled out of the dust master seat, the dust flap springs back automatically and, due to the closed dust window and the structure of the dust flap, will not bounce back and eject too much to ensure continuous and effective protection of the inline insert.
