[embodiment]

Please refer to Fig. 1, disclosed the utility model execution mode electronic product 100.Described electronic product 100 comprises fixture 40, function expanding module 10 and bayonet connector 20.

Please, disclosed the utility model execution mode fixture 40 together with reference to Fig. 2.Described fixture 40 comprises roof 42, pair of sidewalls 44, rear wall 46 and a pair of relative holding parts 48.Described sidewall 44 links to each other with roof 42, and described rear wall 46 links to each other with roof 42 with described sidewall 44.The front end of described roof 42 is provided with the lug boss 422 of rectangle, is used for electronic building brick higher on the accommodation function expansion module 10 12.Described lug boss 422 is provided with a plurality of through holes 424, is used for the heat that the electronic building brick 12 on the sending-forth function expansion module 10 produces.Each sidewall 44 comprises front side wall 442 and 444, two front side walls 442 of rear wall toward each other, and two rear walls 444 toward each other.In the present embodiment, distance between two front side walls 442 is littler than the distance between two rear walls 444, with corresponding with the side wall construction of bayonet connector 20, and the distance between two sidewalls 44 of fixture of the present utility model 40 is slightly less than the width of bayonet connector 20.Described fixture 40 is made for plastic material, has certain toughness and elasticity.

Please, be depicted as the partial enlarged drawing at the III place among Fig. 2 together with reference to Fig. 3.Each holding parts 48 comprises the fixing wall 486 of a rectangle.Two fixing walls 486 link to each other with roof 42.Two fixing walls 486 link to each other with two front side walls 442 respectively, and between fixing wall 486 and front side wall 442 slit 482 are arranged, and are used to increase the elasticity of holding parts 48.The bottom of described fixing wall 486 is provided with the hook portion 484 of a pair of " L " shape.Distance between two fixing walls 486 is slightly less than the width of function expanding module 10.In other execution mode of the present utility model, described fixing wall 486 quantity are not limited only to a pair of, and the quantity of the hook portion 484 of the bottom of each fixing wall 486 also is not limited only to a pair of.

Please refer to Fig. 4, the bottom of described rear wall 46 is provided with breach, and the bottom of described hook portion 484, rear wall 46 and sidewall 44 is equipped with chamfering 448, so that the installation of fixture 40.

During assembling electronic product 100, at first function expanding module 10 is inserted in the bayonet connector 20, then fixture 40 is aligned bayonet connector 20 and press down, because the sidewall 44 and rear wall 46 bottoms of fixture 40 of the present utility model are provided with chamfering 448, bayonet connector 20 slips in the fixture 40 along chamfering 448.Because the distance between two sidewalls 44 of fixture 40 is slightly less than the width of bayonet connector 20, and fixture 40 is made for plastic material, has certain elasticity and toughness, and the bottom of rear wall 46 is provided with breach, therefore two sidewalls 44 of fixture 40 of the present utility model can open and tighten the sidewall of bayonet connector 20 slightly, make the sidewall of bayonet connector 20 tighten function expanding module 10.Owing between holding parts 48 and the front side wall 442 slit 482 is arranged, and fixture 40 makes for plastic material, thereby holding parts 48 has certain toughness and elasticity.In the process that presses down fixture 40, when holding parts 48 touched function expanding module 10, holding parts 48 was subjected to the extruding of function expanding module 10 and strain takes place, and function expanding module 10 slips in the fixture 40 along chamfering 448.After function expanding module 10 slipped in the fixture 40, holding parts 48 restored to the original state.Because the distance between two fixing walls 486 is slightly less than the width of function expanding module 10, so fixing wall 486 can tighten the both sides of function expanding module 10, the bottom that the hook portion 484 of fixing wall 486 bottoms is held function expanding module 10.

After fixture 40 is installed on the bayonet connector 20, because the hook portion 484 of fixture 40 is fastened in the bottom of function expanding module 10, function expanding module 10 is fastened in bayonet connector 20 inside, thereby function expanding module 10 also is bound by fixture 40 on the bayonet connector 20, make that fixture 40 can be because of vibrations, and upspring and come off from bayonet connector 20.

Fixture 40 of the present utility model does not need to open up the required space of fixing device for installing on circuit board (not shown), and can plug by hand by the both sides of two sidewalls, 44 clamping bayonet connectors 20, and fitting operation is convenient, has improved efficient, has reduced cost.
