Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-2.

Referring to fig. 1, for the utility model discloses a two-core plug inner shell, including body 1, body 1 includes casing 11 and casing 12 down, and one side of going up casing 11 articulates in casing 12 down on one side, has seted up the cavity 121 that is used for installing metal block and wire in casing 12 down. The metal block and the lead are installed in the cavity 121, and the upper housing 11 can cover the lower housing 12 after rotating in the direction close to the lower housing 12, so that the metal block and the lead are fixed.

Referring to fig. 1 and 2, outer walls of an upper casing 11 and a lower casing 12 are rough, after the upper casing 11 is covered on the lower casing 12, the body 1 is divided into a first installation section 13 and a second installation section 14 along a direction perpendicular to a rotation axis of the upper casing 11, the first installation section 13 includes one ends of the upper casing 11 and the lower casing 12, and the second installation section 14 includes the other ends of the upper casing 11 and the lower casing 12.

The outer wall of first installation section 13 is the cuboid, offers two perforation 131 that supply the sheetmetal to pass on the casing 12 down, and two perforation 131 are seted up and are kept away from the both ends tip of 14 one sides of second installation section in first installation section 13, and run through the one side that second installation section 14 was kept away from to first installation section 13.

The outer wall of the second installation section 14 is a quadrangular frustum pyramid, two through holes 141 for the lead to pass through are provided at one ends of the upper casing 11 and the lower casing 12 far away from the through hole 131, two through holes 141 are provided at two end parts of the second installation section 14 far away from one surface of the first installation section 13, and penetrate through one surface of the second installation section 14 far away from the first installation section 13. The through hole 141 is opened in half in the upper case 11 and in half in the lower case 12.

The two through holes 131 correspond to the two through holes 141 one by one, and the two metal blocks and the wires connected to the metal blocks can respectively penetrate through the two groups of through holes 131 and the through holes 141 and extend out of the body 1.

Referring to fig. 1, a fixture block 2 is disposed on one surface of the upper housing 11 connected to the lower housing 12, and the fixture block 2 is disposed on the first mounting section 13. The fixture block 2 comprises a connecting block 21 and a clamping block 22, one end of the connecting block 21 is connected to one side of the upper shell 11 connected with the lower shell 12, and the other end of the connecting block is connected to the clamping block 22. The clamping block 22 has elasticity, and the side surface of the clamping block 22 is an arc surface.

The clamping groove 122 for inserting the clamping block 2 is formed in one surface of the upper shell 11 of the lower shell 12, the clamping groove 122 is formed in the first mounting section 13, and the clamping groove 122 penetrates through one surface, far away from the upper shell 11, of the lower shell 12. After the upper housing 11 is covered on the lower housing 12, the fixture block 2 can be clamped in the clamping groove 122, so that the upper housing 11 is clamped on the lower housing 12.

The lower housing 12 is further provided with a bump 3 on a surface thereof connected to the upper housing 11, the bump 3 is disposed on the second mounting section 14 and disposed between the two through holes 141, and a positioning hole 31 is formed on a surface of the bump 3 away from the lower housing 12. Correspondingly, a positioning block 4 capable of being inserted into the positioning hole 31 is arranged on one surface of the upper shell 11 connected with the lower shell 12, and the positioning block 4 is arranged on the second mounting section 14.

Distance between 11 one end of last casing and the locating hole 31 opening is kept away from to locating piece 4 is greater than the fixture block 2 and keeps away from the distance between 11 one end of last casing and the draw-in groove 122 opening, make when fitting casing 11 lid down casing 12, locating piece 4 inserts locating hole 31 can be in draw-in groove 122 prior to fixture block 2 joint, thereby make locating piece 4 and locating hole 31 play the positioning action to the joint of fixture block 2 and draw-in groove 122, be difficult for appearing positioning error when making fixture block 2 joint in draw-in groove 122, and then make joint between them can pinpoint, realize going up the accurate positioning of casing 11 on casing 12 down, the effect of casing 11 and lower casing 12 joint has in the being convenient for.
