The upper casing of described shell and lower casing are stainless steel and make.

By adopting above-mentioned technical solution, the utility model has obtained following technological merit and effect: the utility model is provided with lock banking stop by adopting in the both sides of glue core, and be engaged in the structure that unlocking handle is set on the glue core, make after being connected between above-mentioned glue core and the shell to be lockable, make the connection of above-mentioned attachment plug more reliable and more stable, the parts dislocation even the loose contact that cause have been avoided because grafting strength is excessive; By adopting especially stainless steel making shell of metal, significantly promoted the firm degree of syndeton, prolonged useful life.By tail end the structure of holding piece is set, has strengthened fixing to soft arranging wire, make soft arranging wire more firm with being connected of jointing at shell.By the structure of the needle-like pin with certain radian adopt to be set, make above-mentioned jointing in inserting gang socket after, the connection between the contact is tightr more reliable.Can reach following technical performance by the reality test:

Insulation impedance: 100M Ω Min;

High pressure: 500V DC conduction impedance 5 Ω;

Product conduction impedance: 40m Ω Max;

Left and right sides LOCK extracts destructive power: 5.0Kg (Min).

In a word, the utility model can provide a kind of easy for installation by adopting above-mentioned a series of structures, firm plug, and the novel jointing of long service life, and this jointing also has good heat-resisting ability.

[embodiment]

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

As shown in Figure 1-Figure 3, the utility model relates to a kind of novel 41 pin exterior buckle type adapter connectors, snap together the shell that constitutes by upper casing 1 and lower casing 2, and be arranged on glue core 3 in the above-mentioned shell, choker block 4 and terminal base 7 and form, above-mentioned glue core 3 and choker block 4 are arranged in the cavity of being made up of upper casing 1 and lower casing 2.Glue core 3 is provided with a sunk part 6, this sunk part 6 is used for installation end stroma 7 and choker block 4, the both sides of this sunk part 6 are provided with the chute 8 that matches with choker block 4 both sides, after being installed in terminal base 7 in the depression position 6 on the glue core 3, utilize choker block 4 and cooperating of glue core 3 upper hopper chutes 8 that terminal base 7 snappings are fixed on the glue core 3, terminal base 7 is provided with the needle-like pin 9 that is arranged in parallel, and this needle-like pin 9 plugs together connection circuit afterwards at above-mentioned adapter connector and connector body.As shown in Figure 4 and Figure 5, the both sides of described shell respectively are provided with lock banking stop 10, this lock banking stop 10 is a U-shaped, and a length of side of this U-shaped, and is short on one side in addition, in the location notch in short one side insertion glue core 3, long top, one side is provided with little hook 11, and this little hook 11 is buckled in the location hole on the connector body sidewall, after glue core 3 and shell are installed, above-mentioned lock banking stop 10 is locked in connector plug on the connector body by little hook 11 disposed thereon.Glue core 3 both sides are provided with unlocking handle 12, this unlocking handle 12 be connected with the long ends of lock banking stop 10, stretch out in the through hole 13 of little hook 11 on it by unlocking handle 12 lower ends, when pulling down above-mentioned adapter connector from connector body, by pressing the unlocking handle 12 on the moulding core 3, can drive lock banking stop 10 actions, make the above-mentioned location hole of little hook 11 from connector body and withdraw from, firmly adapter connector can be extracted then.In order to guarantee the bonding strength between wire rod and the adapter connector, be provided with intilted holding piece 14 at the tail end of described upper casing 1 and lower casing 2.This holding piece 14 clamps wire rod by two holding pieces 14 when shell is fastened on the glue core 3, can prevent friction between wire rod and shell and the glue core 3, the problem that causes wire rod to damage.

Be fixed with wire rod on the described choker block 4, the general employing pastes wire rod earlier on the choker block 4, then wire rod and choker block 4 are installed on the glue core 3, cooperate with slideway 8 in the glue core 3 by choker block 4 both sides, and the needle-like pin 9 in choker block 4 is packed glue core 3 into are connected with wire rod.Adopt this fabricated mounting means, can save the welding process in the assembling process, significantly reduce production costs.Adopt this fabricated structure, can also when adapter connector is breaking down, keep in repair by the mode of changing parts.

As shown in Figure 6 and Figure 7, the zone that the front end of the needle-like pin 9 on this adapter connector and the contact interlocking on the connector body touch is provided with radian, it is tightr that it is contacted with contact on the connector body, and conductivity is more stable, avoids adapter connector and connector body to inserting the back loose contact.The structure of the front end of needle-like pin and glue core 3 couplings be different from like product with the common formula that takes all of structure, original structure can cause interference to ground connection to functions such as signal transmission.So what adopt in the utility model is the structure that is similar to the USB connector conductor, the tip of needle-like pin 9 is provided with the C angle, glue core 3 is provided with the bit-avoiding slot that is complementary with needle-like pin 9, make needle-like pin 9 thrust glue core 3 bit-avoiding slots, only the needle-like pin has the radian face to contact with connector body, spigot and bottom thereof are surrounded by glue core 3, avoid functions such as ground connection are caused interference.Of the present utility model the spigot both sides are respectively equipped with radian, itself and connector body are closely cooperated, avoid adapter connector and connector body inserting the back and be difficult for loosening and producing the loose contact phenomenon.This needle-like pin 9 is an assembled with glue core 3 in addition, the MD terminal base that the utility model is made up of 41 needle-like pins.Terminal base 7 both sides and glue core 3 block during assembling, and the tail end of this structure needle-like pin 9 and wire rod also are assembled, and wire rod PH is 0.50, with wire welding type processing inconvenience, now make assembled into.The upper casing 1 of described shell and lower casing 2 are stainless steel and make.

Foregoing description can only be counted as preferred embodiment.Professional and technical personnel in the art and manufacturing or use people of the present invention should recognize other multiple variation pattern of the present invention.Therefore, it being understood that the above-mentioned illustrated embodiment usefulness that only presents a demonstration, it can't be construed as limiting scope of the present invention, scope of the present invention by according to the principle of Patent Law, comprise that the following claim that the principle of equivalent is explained limits.
