The positioning terminal using the interior thread sealing comprises a shell and a charging terminal, wherein the charging terminal is arranged in the shell; a sealing ring is arranged between the charging terminal and the inner wall of the shell; and threads are arranged in the sealing ring. The positioning terminal prevents an exterior sealing component from being separated and damaged when used, and the interior sealing way has no influence on the charging way; the positioning terminal is attractive in appearance and good in sealing effect, the exterior sealing component is not required to be arranged, threading degree of the sealing can be tightened through the threads, and sealing quality is improved.
Description
Technical field
The utility model relates to a kind of locating terminal, especially relates to a kind of inner locating terminal that adopts thread seal, belongs to the communications field.
Background technology
Charging is the process that the equipment such as accumulators replenishes electric weight.Its principle is to allow 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 by charging after discharge consumes at its energy, can again discharge again, consists of to charge and discharge circulation.General with direct current (also useful asymmetrical alternating current electric current or pulse current) charging.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, such as the test of lead acid batteries charger, valve-control sealed lead acid battery and monitoring, electricity charger for Ni-Cd battery, nickel-metal hydride 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 to consume electric energy; so need to charge to it; be provided with charging socket on the locating terminal; because charging socket is open hole, be communicated with the inside of locating terminal, sometimes have a lot of dusts or steam in the environment difference of using; charging socket often can be stopped up or moisture attacks by dust; inner member to locating terminal has caused damage, affects the useful life of locating terminal, need to consider the sealing to locating terminal to this.Traditional sealing means is the outer setting seal that adopts at 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 impact, and the outside seal mode needs more complicated charging scheme.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of inner locating terminal that adopts thread seal 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 on charging modes without any impact, good looking appearance, sealing effective need not additionally to increase outer seal, can clamp the degree of screwing of sealing by screw thread, improve airtight quality.
The purpose of this utility model is achieved through the following technical solutions: the inner locating terminal that adopts thread seal, comprise housing and charging terminal, described charging terminal is arranged on enclosure interior, is provided with sealing ring between described charging terminal and the inner walls, and described sealing ring inside is provided with screw thread.
Be provided with the charging socket that communicates with inside on the described housing, be provided with sealing ring between described charging socket and the charging terminal.
The quantity of described charging socket is four.
The quantity of described sealing ring is four, and connects as one successively structure.Adopt integrative-structure, sealing ring and charging socket can be realized collaborative sealing.
The internal diameter of described sealing ring is greater than the diameter of the charging socket of correspondence.
Described sealing ring adopts waterproof material to make.Utilize the sealing of waterproof material, by the extruding between housing and the charging terminal, realize that sealing ring is close near the charging socket, with the inner and extraneous realization sealing of locating terminal.
In sum, the beneficial effects of the utility model are: this locating terminal has been avoided outer seal in use to have breaking away from and the risk of infringement, and the inner sealing mode on charging modes without any impact, good looking appearance, what seal is effective, need not additionally to increase outer seal.
Description of drawings
Fig. 1 is structural representation of the present 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 described in further detail, but execution mode of the present utility model is not limited only to this.
Embodiment 1:
As shown in Figure 1, the inner locating terminal that adopts thread seal comprises housing 1 and charging terminal 4, and described charging terminal 4 is arranged on housing 1 inside, is provided with sealing ring 2 between described charging terminal 4 and housing 1 inwall.Between housing 1 and charging terminal 4, add sealing ring, by the extruding between housing 4 and the charging terminal 4, sealing ring 2 is filled up the space of 1 of charging terminal 4 and housing, reach good sealing effectiveness, reach in the situation that does not change outward appearance and realize obturation effect.
Be provided with the charging socket 3 that communicates with inside on the described housing 1, be provided with sealing ring 2 between described charging socket 3 and the charging terminal 4.Charging socket 3 is locating terminal and the extraneous window that contacts, owing to the technique of machinery or according to precision, always there is certain gap, airborne dust or steam easily enter locating terminal inside, element to inside causes damage, affects 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 described charging socket 3 is four.The quantity of described sealing ring 2 is four, and connects as one successively structure.Adopt integrative-structure, sealing ring 2 and charging socket 3 can be realized collaborative sealing, reduced simultaneously middle operation, improved production efficiency.
The internal diameter of described 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, if the internal diameter of sealing ring 2 less than the diameter of charging socket 3, can hinder entering of plug, bring inconvenience to charging.
Described sealing ring 2 adopts waterproof material to make.Utilize the sealing of waterproof material, by the extruding between housing 1 and the charging terminal 4, realize that sealing ring 2 is close near the charging socket 3, with the inner and extraneous realization sealing of locating terminal.
Embodiment 2:
The structure of the present embodiment and embodiment 1 is basic identical, and its difference only is: described sealing ring 2 inside are provided with screw thread.Sealing ring 2 is inner owing to will pass through the power line of charging, and sealing ring 2 adopts waterproof materials to make, and has certain frictional force, require great effort very much in insertion and withdrawal process, after screw thread is set, can screws rapidly and enter charging, reduce trouble, improved simultaneously the useful life of equipment.
Take aforesaid way, just can realize preferably the utility model.
