Spool, tray and reel constituted of spool and tray

Abstract

A reel is constituted of two kinds of members including a spool and two trays. The spool and the tray are provided on the connecting surfaces with the same amount of the means to be hooked and the hooking means for hooking with each other. In this way, the spool and the tray can be connected with each other to form a reel for winding and fixing a tape. Further, one set of the means to be hooked and the hooking means has an idiot-proof design, so that they cannot be assembled with each other if only they are correctly aligned. With this idiot-proof design, the operators can easily recognize it to improve the guiding effect so as to prevent the mistake in assembling.

1 . A spool of a reel, the faces on both sides of the spool provided with a plurality of means to be hooked arranging in an annular form, each means to be hooked comprising two pieces to be hooked, an insertion groove formed between the two pieces to be hooked, and the insertion groove of one means to be hooked different from that of the other means to be hooked in shape. 
   
   
       2 . The spool of a reel according to  claim 1 , wherein the spool is an annular body having an inner hole, and the plurality of means to be hooked extend inwardly from the wall face of the inner hole. 
   
   
       3 . The spool of a reel according to  claim 1 , wherein the outside of the spool has at least one recessed insertion groove for a carrier tape. 
   
   
       4 . A tray of a reel, a plurality of hooking means arranging in an annular form and extending from one side of the tray, each hooking means comprising an elastic hook and a rib, and the rib of one hooking means different from that of the other hooking means in shape. 
   
   
       5 . The tray of a reel according to  claim 4 , wherein the elastic hook and the rib are connected to each other. 
   
   
       6 . The tray of a reel according to  claim 5 , wherein the rib is provided in the middle position of the elastic hook. 
   
   
       7 . The tray of a reel according to  claim 4 , wherein the tray is provided with a central hole. 
   
   
       8 . The tray of a reel according to  claim 4 , wherein the surface of the tray is provided with a plurality of hollowed grooves. 
   
   
       9 . A reel, comprising:
 a spool, the faces on both sides of the spool provided with a plurality of means to be hooked arranging in an annular form, each means to be hooked comprising two pieces to be hooked, an insertion groove formed between the two pieces to be hooked, and the insertion groove of one means to be hooked different from that of the other means to be hooked in shape; and   two trays for connecting to the faces on both sides of the spool, a plurality of hooking means arranging in an annular form and extending from one side of the tray, each hooking means comprising an elastic hook and a rib, and the rib of one hooking means different from that of the other hooking means in shape;   wherein the means to be hooked and the hooking means are provided with the same amount, and they are capable of aligning and connecting with each other.   
   
   
       10 . The reel according to  claim 9 , wherein the spool is an annular body having an inner hole, and the plurality of means to be hooked extend inwardly from the wall face of the inner hole. 
   
   
       11 . The reel according to  claim 9 , wherein the outside of the spool has at least one recessed insertion groove for a carrier tape. 
   
   
       12 . The reel according to  claim 9 , wherein the elastic hook and the rib are connected to each other. 
   
   
       13 . The reel according to  claim 12 , wherein the rib is provided in the middle position of the elastic hook. 
   
   
       14 . The reel according to  claim 9 , wherein the tray is provided with a central hole. 
   
   
       15 . The reel according to  claim 9 , wherein the surface of the tray is provided with a plurality of hollowed grooves.
