Description

The structure-improved of communication connection box

Technical field

The utility model relates to a kind of structure-improved of communication connection box, particularly the communication connection box of anti-mis-insertion.

Background technology

Nowadays, the communication prosperity, general Communication Equipment, as: facsimile machine, phone, computer, the photocopier of tool facsimile function etc., all there is the communication connection box 10 of network joint RJ45 or these two kinds of standards of telephone jack RJ11 to be arranged on the equipment for use, wherein the standard of RJ45 is the standard that network uses, the standard that the RJ11 standard is then used for regular phone, shown in Fig. 2 A and Fig. 2 B, the connecting line plug 101 of RJ45 standard has eight grooves to bury formula underground to contact terminal plate 103, bury formula underground and contact terminal plate 103 and RJ11 connecting line plug 201 is six grooves, other physical dimension is all identical, and RJ45 and RJ11 two standards are only at the socket and the joint 101 of communication connection box 10,201 width slightly on difference slightly.

Fig. 1 E is the communication connection box 10 of RJ45 and the perspective diagram that RJ45 connecting line plug 101 normally plugs together, as shown in the figure, wherein reed terminal 10a has and upwards buries formula underground with eight grooves of RJ45 connecting line plug 101 and contact the elevation angle that terminal plate 103 contacts conducting.

Communication connection box 10 sockets and RJ45 connecting line plug 101 and RJ11 connecting line plug 201 because of RJ45, RJ11 two standards, difference slightly on width only, shown in Fig. 2 A and Fig. 2 B, and general hardware device all is provided with the communication connection box 10 of RJ45, RJ11 simultaneously, so, the user is often arranged shown in Figure 1A～Fig. 1 D, mistake connects the communication connection box 10 that RJ11 connecting line plug 201 inserts RJ45 by force.Because reed terminal 10a wherein can't bury the corresponding contact of reed terminal 10a that formula contacts terminal plate 103 underground with the groove of RJ11 connecting line plug 201, owing to causing excessive exerting oneself under the situation of inserting by force, cause first and last reed terminal 10a damage in the RJ45 communication connection box 10 easily, mainly be because of being subjected to 201 liang of side bottom compressings of RJ11 connecting line plug deformed damaged, can't normally contacting conducting and use.

For overcoming above-mentioned defective, the applicant once proposed No. 200420117612.0 patent of Chinese utility model that notification number is CN2765342Y, as Fig. 3 A～shown in Figure 4, can prevent that the situation that misplugs and damage from taking place.Yet, for making structure more reasonable, the applicant studies above-mentioned application, both sides, communication connection box 30 interior top are provided with metal roof spring arrangement 40 and fix by its slotting portion 402, the curved top 401 inboard scarf 401a of front end bending by top spring arrangement 40 stop the insertion of incorrect connecting line plug 202; But, as the incorrect connecting line plug 202 of long-term acceptance by force the application of force misplug action, might cause two top spring arrangements 40 to both sides expansion displacement, and might stab out the two side of communication connection box 30, when being subjected to powerful the insertion, still have misplug into damage the possible of reed terminal 40c.

The utility model content

For preventing that the incorrect connecting line plug of the long-term stressed prevention of two top spring arrangements from expanding displacement to both sides, make the effect forfeiture of prevention, the utility model provides a kind of new structure.

The utility model provides a kind of structure-improved of communication connection box, this communication connection box has the openend that can insert the connecting line plug and the blind end of leading-out terminal, the reed terminal is arranged on this communication connection box below, it is characterized in that, both sides are oppositely arranged pair of metal top spring arrangement above in communication connection box, one end of this metal roof spring arrangement is fixed on above-mentioned blind end by inserting portion, this top spring arrangement is at the cambered surface top down that has a bending near openend one side, this inside top has the scarf that broadens gradually to above-mentioned blind end from above-mentioned openend, make the scarf of pair of metal top spring arrangement in described communication connection box, form gradually narrow inlet, the convex arc sheet that described scarf extends internally out near blind end one side setting, when incorrect connecting line plug when above-mentioned openend inserts, gradually narrow inlet that above-mentioned scarf forms and above-mentioned convex arc sheet stop the insertion of connecting line plug, when correct connecting line plug when above-mentioned openend inserts, the end face that above-mentioned top is connected the line plug upwards lifts, and the connecting line plug is inserted smoothly.
