When the multi-pole plug structure is inserted into and removed from the mating connector, the user can hold the plastic housing to complete the insertion and removal operation. However, since the above-mentioned multi-pole plug structure has a rectangular block shape, the plastic outer casing is easily loosened from the insulating body, so that the user inserts the multi-pole plug structure into the mating connector and pulls out from the docking connector by holding the plastic outer casing. The operation is more difficult. [New content] The purpose of the present invention is to provide a multi-pole connector which can increase the bonding strength between the insulating body and the plastic casing to prevent the plastic casing and the insulating body from coming loose, in view of the defects of the above-mentioned prior art. In order to achieve the above object, the multi-pole connector of the present invention comprises an insulative body, the insulative housing has a body portion, a boss is protruded from the body portion, a positioning hole is formed on the boss, and the boss is also protruded There is a plug portion, and a plurality of terminal card slots are arranged side by side on the plug portion. Conductive terminals are inserted into the 5 M346206 in each of the terminal card slots. A metal housing is sleeved on the plug portion, and a plug connector is fixedly inserted into the positioning hole. The plastic body has a plastic outer casing. The plastic outer casing has a plastic body. The front end of the plastic body is formed with a stepped receiving groove. The main body portion is received in the receiving groove, and the protruding portion is flush with the front end of the plastic outer casing. . As described above, the multi-pole connector of the present invention is matched with the stepped receiving groove by the boss of the insulating body, thereby increasing the bonding strength between the insulating body and the plastic outer casing, thereby preventing the plastic outer casing and the insulating body from being loosened, thereby The operation of inserting the multi-pole connector into the docking connector and pulling it out from the docking connector can be more accurate and reliable. [Embodiment] In order to explain the technical contents, structural features, objectives and effects of the present invention in detail, the embodiments are described below in detail with reference to the drawings. Referring to the first, second and third figures, the multi-pole connector 1 of the present invention comprises an insulative housing 10 having a body portion 100 in the shape of a square block. The front end surface of the body portion 100 is convex. There is a boss, and a circular positioning hole 102 is defined in the right portion of the boss 101, and the positioning hole 1〇2 extends through the body portion 100 backward. A rectangular slot 103 is formed in the left portion of the boss 101. The bottom slot wall of the slot 103 protrudes forwardly from a square plug portion 1?4, and a front side of the plug portion 104 is rearwardly opened. Plug in. 1〇5. The upper wall of the plug connector 105 is provided with a plurality of side faces of the terminal card slot tracking portion 104 extending side by side to the rear end surface of the body portion, and a joint portion of the top surface and the bottom surface is respectively provided with a circular arc-shaped foolproof Matching part 1G7. A through hole 108 is defined in each of the two sides of the plurality of terminal card slots 1 at the rear of the main body portion M346206, and the through hole 1〇8 communicates with the slot 1〇3. Referring to FIG. 2, FIG. 4 and FIG. 5, the insulative housing 10 is provided with a plurality of conductive terminals 20, and the conductive terminals 20 include two first conductive terminals 21 and two second conductive terminals 22. The first conductive terminal 21 has a sheet-like holding portion 210. The front end of the holding portion 210 is formed to protrude into a strip-shaped connecting portion 211. The front end of the connecting portion 211 has a latching tooth 212 projecting downward. The lower portion of the rear end edge of the holding portion 210 protrudes rearward and extends downward to be bent to the left to form a first welded portion 213. The structure of the second conductive terminal 22 is substantially the same as that of the first conductive terminal 21, and has a holding portion 220, a connecting portion 221 and a latching portion 222; the second conductive terminal 22 is different from the first conductive terminal 21 in that the second conductive terminal 22 is different from the first conductive terminal 21 The upper portion of the rear end edge of the holding portion 220 protrudes rearward and extends upward and then bends to the right to form a second welded portion 223. The two first conductive terminals 21 and the two second conductive terminals 22 are alternately arranged, and the holding portion 210 and the holding portion 220 are respectively received in the terminal card slots 1〇6, and the first soldering portion 213 and the second soldering portion 223 are convex. The rear end surface of the body portion 100 is exposed to be soldered to a corresponding circuit contact (not shown). The plug portion 104 is sleeved with a metal casing 3〇 which is cut from a metal plate and bent and formed. The metal casing 3 has a bottom wall 300, a top wall 310 and two side walls 320. A locking hole 3U is defined in the top wall 31, and the card L 311 can be engaged with a buckle (not shown) on the mating connector to increase the holding force between each other. The rear end edges of the two side walls 32 are respectively protruded rearward with a substantially strip-shaped ground portion milk. The upper and lower edges of the side wall 320 of the left side M346206 and the joint of the bottom wall 300 and the top wall 310 respectively form an arc-shaped anti-slipping angle 321 which is located outside the corresponding anti-dwelling fitting portion 107. When the multi-connector connector of the present invention is inserted into the docking connector (not shown), the anti-slipping angle 321 can play a foolproof effect; in fact, in order to achieve the foolproof effect, any one of the metal casings 30 can be used. An anti-sag angle 321 is provided at an angular corner or at an adjacent corner or any triangular corner. The end of the grounding portion 32" 2 passes through the through hole 108 and protrudes from the rear end surface of the body portion 100 to be welded to a corresponding circuit contact (not shown) to achieve grounding. A rod-shaped plug connector 40 is inserted into the positioning hole 102 of the insulative housing 1 . The plug connector 40 is a quadrupole plug, and includes a plastic body. The plastic body 400 has a positioning portion 405 at the end thereof. The positioning portion 4〇5 is inserted into the positioning hole 1〇2. A first contact portion 401, a second contact portion 402, a third contact portion 4〇3 and a fourth contact portion 404 are respectively disposed on the plastic body 400. The first contact portion 401, the second contact portion 4〇2, the third contact portion 403, and the fourth contact portion 404 are separated by a plastic body 4〇〇 and extend to the end of the plastic body 400, respectively. The tail portion of the positioning portion 405 is pierced to be connected to a corresponding circuit contact (not shown). Referring to the first, second and sixth figures, the body portion 100 of the insulating body is sleeved with a plastic outer casing 50, and the plastic outer casing 50 is injection molded on the insulating body W. The plastic housing 50 has a plastic body 5〇〇. One end of the plastic body 500 is formed with a stepped receiving groove 501. When the insulative housing 10 is received in the receiving slot 501, the main body portion 1 is wrapped by the plastic housing 50. The front end surface of the boss 101 is flush with the front end surface of the plastic housing 50, and the 8 M346206 is received by the stepped receiving slot 501. Cooperating with the boss 101 can increase the bonding strength between the insulating body 10 and the plastic case 50. As described above, the multi-pole connector 1 of the present invention cooperates with the stepped receiving slot 501 by the boss 101 on the insulative housing 10, thereby increasing the bonding strength between the insulative housing 10 and the plastic housing 50, and avoiding the plastic housing. The loosening of the insulating body makes the operation of the present multi-connector connector 1 inserted into the docking connector and pulled out from the docking connector more accurate and reliable.
