As the improvement to such scheme, the contact-making surface of described raised line and step surface is the long inclined plane of length.For the ease of operation, be provided with the draw ring of being convenient to spur the unlock piece slip in the unlock piece rear end.

As further improvement of these options, described shell upper casing, the mutual buckle of lower casing, between upper casing and the lower casing by rivet and be arranged at upper casing, lower casing buckle position fixes.The buckle position of being adopted comprises the Ka Tai that is arranged at upper casing, the engaging of lower case side wall mutual dislocation.

In order to improve the stability and the antijamming capability of signal conduction, be with the conductive ring of a stabilization signal in the shell stage casing.

Compared with prior art, the utility model structure is more succinct, and plug is also convenient, can realize quick-speed plug, and dependable performance is stable, and is practical, adopts two pcb board transmission signals arranged side by side, has higher effectiveness.And this structure outward appearance can be accomplished cleaner and tidier, and the inner space utilance is higher, though from design, or produce and all have good advance in the operation.Simultaneously, also can increase the stability and the antijamming capability of signal conduction by setting up conductive ring.

Be further detailed below in conjunction with accompanying drawing.

[embodiment]

Understand for the ease of this area engineers and technicians, will and be described in detail the utility model in conjunction with the accompanying drawings by specific embodiments below.

Shown in accompanying drawing 1～4.The disclosed high speed CXP interface module of this programme structure comprises the shell of being made up of upper casing 12, lower casing 13 1 and is installed on two pcb boards arranged side by side 2 in the shell 1, is installed on the latching device 3 of being convenient to the whole module of quick-speed plug on the shell 1.

Wherein, upper casing 12 and lower casing 13 mutual buckles, and between upper casing 12 and the lower casing 13 by rivet 5 and be arranged at upper casing 12, lower casing 13 buckle positions 14 fix.This buckle position 14 comprises the card platform 141,142 that is arranged at upper casing 12, the engaging of lower casing 13 sidewall mutual dislocation, realize the location of inner end longitudinal direction between upper casing 12 and the lower casing 13 by the engaging of two Ka Tai, by rivet 4 rear end is fixed again, formed constitutionally stable shell thus.

In this programme, the latching device 3 that is adopted comprises a snap close piece 31 and a unlock piece 32, and snap close piece 31 is an elastic sheet metal, and its outer end is fixed on the shell 1 by rivet 5, and is inner unsettled and be provided with crooked back-off 311; This unlock piece 32 is slidedly arranged between snap close piece 31 and the shell 1, and its inner end is provided with the big raised line 321 of thickness, and is provided with a step surface 11 that tilts at shell 1 upper surface, and raised line 321 is positioned at the space of step surface 11 and snap close piece 31 formation.For the ease of the distortion of more swimmingly snap close piece 31 to be arched upward of unlock piece 32 raised line 321 when outwards sliding, raised line 321 is designed to the long inclined plane of length with the contact-making surface of step surface 11, and is provided with the draw ring 4 of being convenient to spur unlock piece 32 slips in unlock piece 32 rear ends.

When this module being assigned in the corresponding jack of connector, the back-off 311 of snap close piece 31 colludes on the corresponding fixed bit of connector plug jack, guarantees that thus whole module can not skid off from connector easily.When needs are extracted this module, only need outwards pulling draw ring 4, draw ring 4 pulling unlock pieces 32 outwards move, the raised line 321 of unlock piece 32 contacts with step surface 11 and arched upward in snap close piece 31 ends in acting in conjunction, back-off 311 is deviate from from the fixed bit of connector plug jack, contact locking thus can be extracted module smoothly.

Meanwhile, in order to increase the stability and the antijamming capability of signal conduction, be with a conductive ring 6 in the shell stage casing.

The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
