Abstract
The utility model discloses a positioning terminal with an internal sealing structure. The positioning terminal comprises a shell and a charging terminal, wherein the charging terminal is arranged in the shell; and sealing rings are arranged between the charging terminal and the internal wall of the shell. Through the positioning terminal, the risk that an external sealing piece is separated from the positioning terminal or is damaged in use is avoided; the internal sealing mode has no effect on the charging mode; and the positioning terminal has an attractive appearance and a good sealing effect and is not required to be provided with the external sealing piece.
Description
Technical field
The utility model relates to a kind of locating terminal, especially relates to a kind of locating terminal that adopts internal seal structure, belongs to the communications field.
Background technology
Charging is the process that equipment such as accumulators replenishes electric weight.Its principle is to let direct current pass through from the opposite direction of discharging, so that active material restitution in the storage battery.Storage battery is accepted electric energy from external circuit, is converted into the course of work of the chemical energy of battery.Storage battery, recovers through charging after discharge consumes at its energy, can discharge again again, constitutes to charge and discharge circulation.Generally charge with direct current (also useful asymmetrical alternating current electric current or pulse current).Under the different situations, adopt the combined charging of different charging methods such as constant current charge, constant voltage charging, floating charge, trickle charge, boost charge or these methods etc.Charger has a lot, like the test of lead acid batteries charger, valve-control sealed lead acid battery and monitoring, ickel-cadmium cell charger, Ni-MH battery charger, charger for lithium ion battery, portable electric appts charger for lithium ion battery, lithium ionic battery protection circuit multifunctional charger, electromobile battery charger, Che Chong etc.Locating terminal itself in use needs consumed power, so need charge to it, locating terminal is provided with the charging socket; Because the charging socket is open hole, is communicated with the inside of locating terminal, sometimes has a lot of dusts or steam in the environment difference of using; The charging socket is stopped up or moisture attacks by dust through regular meeting; Inner member to locating terminal has caused damage, influences the useful life of locating terminal, need consider the sealing to locating terminal to this.Traditional sealing means is the outer setting seal that is employed in locating terminal, and outer seal in use has and breaks away from and the risk of infringement, the sealing effectiveness of locating terminal has been caused influence, and the outside seal mode needs complicated more charging scheme.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art; A kind of locating terminal that adopts internal seal structure is provided; This locating terminal has avoided outer seal that the risk that breaks away from and damage is in use arranged, and the inner sealing mode has no influence to charging modes, good looking appearance; Favorable sealing effect need not extra increase outer seal.
The purpose of the utility model realizes through following technical proposals: adopt the locating terminal of internal seal structure, comprise housing and charging terminal, said charging terminal is arranged on enclosure interior, is provided with sealing ring between said charging terminal and the inner walls.
Said housing is provided with and the inner charging socket that communicates, and is provided with sealing ring between said charging socket and the charging terminal.
The quantity of said charging socket is three.
The quantity of said sealing ring is three, and connects as one structure successively.Adopt integrative-structure, can sealing ring and charging socket be realized collaborative sealing.
The internal diameter of said sealing ring is greater than the diameter of the charging socket of correspondence.
Said sealing ring adopts rubber to process.Utilize the pliability of rubber,, realize that sealing ring is close near the charging socket, realizes sealing with locating terminal inside with the external world through the extruding between housing and the charging terminal.
In sum; The beneficial effect of the utility model is: this locating terminal has avoided outer seal that the risk that breaks away from and damage is in use arranged, and the inner sealing mode has no influence to charging modes, good looking appearance; Favorable sealing effect need not extra increase outer seal.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark and corresponding parts title in the accompanying drawing: 1-housing; 2-sealing ring; 3-charging socket; 4-charging terminal.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the execution mode of the utility model is not limited only to this.
Embodiment 1:
As shown in Figure 1, the locating terminal of employing internal seal structure comprises housing 1 and charging terminal 4, and said charging terminal 4 is arranged on housing 1 inside, is provided with sealing ring 2 between said charging terminal 4 and housing 1 inwall.Between housing 1 and charging terminal 4, add sealing ring,, sealing ring 2 is filled up the space of 1 of charging terminal 4 and housing, reach good sealing effectiveness, reach under the situation that does not change outward appearance and realize obturation effect through the extruding between housing 4 and the charging terminal 4.
Said housing 1 is provided with and the inner charging socket 3 that communicates, and is provided with sealing ring 2 between said charging socket 3 and the charging terminal 4.Charging socket 3 is locating terminal and the extraneous window that contacts, because always there is certain clearance in the technology of machinery perhaps according to precision; Dust in air or steam get into locating terminal inside easily; Element to inside causes damage, influences useful life, utilizes sealing ring 2 with clearance seal; Dust or steam in can secluding air enter into locating terminal inside, have prolonged the useful life of element.
The quantity of said charging socket 3 is three.
The quantity of said sealing ring 2 is three, and connects as one structure successively.Adopt integrative-structure, can sealing ring 2 and charging socket 3 be realized collaborative sealing, reduced middle operation simultaneously, improved production efficiency.
The internal diameter of said sealing ring 2 is greater than the diameter of the charging socket 3 of correspondence.When charging, need plug to insert in the charging socket 3,, bring inconvenience to charging if the internal diameter of sealing ring 2 can hinder the entering of plug less than the diameter of charging socket 3.
Said sealing ring 2 adopts rubber to process.Utilize the pliability of rubber,, realize that sealing ring 2 is close near the charging socket 3, realizes sealing with locating terminal inside with the external world through the extruding between housing 1 and the charging terminal 4.
Take aforesaid way, just can realize the utility model preferably.
