Description

I/O connector

technical field

The utility model relates to a connector, in particular to an input and output connector.

Background technique

Please refer to FIG. 5, which discloses a traditional input-output connector 100', the input-output connector 100' includes an insulating body 1', a shell 2' and a number of conductive terminals 3 inserted on the insulating body 1' `. The insulating body 1' has a locking block 11', and the housing 2' is provided with a fixing hole 21'. The insulating body 1 ′ and the housing 2 ′ are fixedly connected together by fitting the locking block 11 ′ into the fixing hole 21 ′.

However, the above-mentioned input-output connector 100' has manufacturing errors between the buckle block 11' of the insulating body 1' and the fixing hole 21' of the housing 2', so the buckle block 11' and the fixing hole 21' usually cannot be tightly engaged. Therefore, the insulating body 1 ′ and the shell 2 ′ will move relative to each other under the action of external force, so that the insulating body 1 ′ and the shell 2 ′ cannot be firmly engaged.

Utility model content

The task of the present utility model is to provide an input-output connector capable of stable connection between the shell and the insulating body in view of the defects in the above-mentioned background technology.

To achieve the above purpose, the input and output connector of the present invention has an insulating body, a housing and a plurality of conductive terminals. The insulating body has a base, and the base is provided with buckle blocks and a plurality of conductive terminal slots. The conductive terminals are inserted into the corresponding conductive terminal slots. The housing is installed on the insulating body, and a fixing hole is opened on the housing, and the housing is provided with a clip protruding from the hole edge of the fixing hole into the fixing hole, and the buckle block is sleeved in the fixing hole. And the tip of the card is stuck against the buckle block.

As mentioned above, since the buckle block is sleeved in the fixing hole of the input and output connector of the present utility model, since the protruding clip tip in the fixing hole can produce a certain amount of elastic deformation, the clip tip can be reliably locked against On the buckle block, relative sliding between the shell and the insulating body is not easy to occur, so that the fastening between the shell and the insulating body is more stable.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the utility model in detail, the following will be described in detail in combination with the embodiments and accompanying drawings.

Please refer to FIG. 1 to FIG. 3 , the input and output connector 100 of the present invention includes an insulating body 1 , a plurality of conductive terminals 2 , two buckle terminals 3 and a housing 4 . The insulating body 1 has a base 11 in the shape of a cuboid. The upper surface of the base 11 is provided with a first fixing groove 12 that runs through the base 11 front and back. The bottom wall of the first fixing groove 12 protrudes from the bottom wall of the first fixing groove. 121.

The rear side of the base 11 is provided with two through holes 13 passing through the base 11 forward, and the rear side of the base 11 protrudes backward with two fixing blocks 14, and the two fixing blocks 14 are used to carry the circuit board (Fig. not shown). A square insertion portion 15 protrudes forward from the front surface of the base portion 11 and arc-shaped surrounding body portions 16 respectively surround the two ends of the insertion portion 15. Between the insertion portion 15 and the two surrounding body portions 16, a a second fixing groove 17 . A front end of the insertion portion 15 defines a square terminal receiving groove 151 .

The base 11 defines a conductive terminal slot 152 extending through the base 11 and extending to the bottom wall of the terminal receiving groove 151 . The base portion 11 defines a snap-on terminal slot 18 extending through the front and rear sides of the base portion 11 and extending to the two side edges of the insertion portion 15 on the left and right sides of the base portion 11 .

Please refer to FIG. 3 , the conductive terminal 2 has a holding portion 21 , a welding portion 22 extends horizontally from one end of the holding portion 21 , and a contact portion 23 extends from the other end. The locking terminal 3 has a locking portion 31 , and one end of the locking portion 31 protrudes vertically outwards to a locking portion 32 .

Referring to FIG. 3 and FIG. 4 , the housing 4 has a rectangular cylindrical shell 41 , and the shell 41 has an upper wall 411 , a lower wall 412 and two side walls 413 connected to the upper wall 411 and the lower wall 412 . The middle part of the rear end edge of the upper wall 411 protrudes backwards with an extension 42, and the extension 42 is provided with several square fixing holes 421, and the extension 42 protrudes inwardly from the edge of the fixing hole 421.
