As shown in fig. 15, two second protrusions 108 are protruded from the sliding groove 107, and a passage for the control handle 204 to pass through is formed between the two second protrusions 108; a first limiting surface 109 is formed on one side, close to the elastic sheet 203, of the second bump 108, a second limiting surface 205 is formed on one side, close to the second bump 108, of the elastic sheet 203, and the first limiting surface 109 and the second limiting surface 205 form limiting fit; in the inward movement process of the diagnosis interface plug-in 201 in the accommodating cavity 102, the first limiting surface 109 and the second limiting surface 205 are abutted to form limiting fit, so that the diagnosis interface plug-in 201 is prevented from being pressed further, the diagnosis interface plug-in 201 is effectively prevented from moving inward, the stable state of the diagnosis interface is ensured, and diagnosis is facilitated. When the diagnostic interface plug-in 201 needs to be retracted into the box body 101 to achieve locking, the control handle 204 needs to be pushed inwards to press one side of the free end of the elastic sheet 203 to the outer wall of the diagnostic interface plug-in 201, so that the first limiting surface 109 and the second limiting surface 205 are dislocated without interference.
A first guiding inclined surface 110 is formed on one side of the second projection 108, which is far away from the spring plate 203, a second guiding inclined surface 206 is formed on one side of the spring plate 203, which is far away from the second projection 108, and the first guiding inclined surface 110 and the second guiding inclined surface 206 form guiding fit. When the diagnostic interface plug-in 201 is pushed by the spring 103 to eject out of the housing, the second guiding inclined surface 206 of the elastic sheet 203 contacts with the first guiding inclined surface 110, so that the motion buffering effect can be effectively achieved.
In order to further improve the protective effect of diagnosis interface plug-in 201 avoids it to expose in the external environment, the open end of box body 101 articulates there is lid 111, and lid 111 adopts the integrated into one piece's that moulds plastics structural style, lid 111 is kept away from one side of hinged end forms turn-ups 112, it has draw-in groove 113 to run through on the turn-ups 112, box body 101 deviates from the protruding fixture block 114 that is equipped with in side of hinged end, when lid 111 overturns to extreme position, draw-in groove 113 and fixture block 114 form the joint cooperation. When diagnosis is not needed, the box cover 111 is turned over to cover the accommodating cavity 102, so that dust prevention, water prevention, foreign matter damage prevention and the like are effectively achieved, and the protection effect is good.
The inner side of the box cover 111 is provided with a first protruding strip 115 and a second protruding strip 116 in a protruding manner, and the first protruding strip 115 and the second protruding strip 116 are arranged in parallel. After the box cover 111 is covered, the first protruding strip 115 and the second protruding strip 116 are both clamped between the diagnostic interface plug-in 201 and the accommodating cavity 102, so that the auxiliary clamping effect is realized.
The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
