Abstract
The utility model relates to an electric connector with a current limiting function. The electric connector takes the front end as the plug end, and comprises a housing, and at least one pair of contact pieces which are assembled in the housing through an insulating body, wherein a current limiting diode is arranged between at least one pair of contact pieces; and two electrodes of the current limiting are respectively welded with the corresponding contact pieces together. As the electric connector with a current limiting function sets the current limiting diode between at least one pair of contact pieces, the corresponding wiring is only required when the electric connector is used for the corresponding requirement for current limiting between one pair or more pairs of wires, thus having no requirement for setting an independent current limiting original in the circuit, and solving the problem that the existing electric connector can not satisfy the current limiting requirement of the circuit.
Description
Technical field
The utility model relates to electric connector field, especially a kind of electric connector with current-limiting function.
Background technology
Electric connector is along with communication, electric the integrated of equipment that wait, modularization develops and is just obtaining using more and more widely, simultaneously, the fast development of use equipment has also proposed more strict requirement to the performance of electric connector and function etc., present electric connector mostly comprises housing and is assemblied in contact in the housing by insulator, only have logical, power down function, when for some the occasion of specific (special) requirements being arranged, just can't be suitable for, as between need to be in circuit a pair of or the electric wire more than two pairs during Unidirectional flow-limiting, traditional electric connector then can't be satisfied the demand, in order to reach the purpose of current limliting, usually need between the corresponding electric wire of circuit, be connected in series in addition the current-limiting components such as Current Limiting Diodes, this understands the volume of increasing circuit on the one hand, do not meet the demand of device miniaturization, the mechanical performance and the environmental resistance that are located on the other hand the independently current limliting components and parts in the circuit are also relatively poor, can reduce the reliability of circuit.
Summary of the invention
The purpose of this utility model is to provide a kind of electric connector with current-limiting function, can't satisfy the problem of the current limliting needs of circuit to solve existing electric connector.
In order to address the above problem, electric connector with current-limiting function of the present utility model is by the following technical solutions: a kind of electric connector with current-limiting function, this electric connector is take front end as inserted terminal, comprise housing and be assemblied at least one pair of contact in the housing by insulator, be provided with Current Limiting Diodes between at least one pair of described contact, the two poles of the earth of described Current Limiting Diodes weld together with corresponding contact respectively.
Described Current Limiting Diodes be externally coated with protective layer.
Described Current Limiting Diodes is encapsulated in the housing by the encapsulating layer that is potted in the housing.
Described encapsulating layer is located at the rear side place of insulator.
The rear side of described encapsulating layer is provided with the numbering plate to the contact numbering.
Because the electric connector with current-limiting function of the present utility model is provided with Current Limiting Diodes between its at least one pair of contact, therefore need to be between one or more pairs of electric wires during current limliting when what be used for correspondence, only need get final product by corresponding wiring, thereby needn't in circuit, establish in addition more independently current limliting original paper, solve the problem that existing electric connector can't satisfy the current limliting needs of circuit.
Further, the protective layer that is coated in the Current Limiting Diodes outside can prevent effectively that Current Limiting Diodes is aging, prolongs its useful life, increases the normal operation cycle of electric connector; Further play the effect of protection Current Limiting Diodes by encapsulating layer encapsulation Current Limiting Diodes, can further guarantee the reliability that is connected between Current Limiting Diodes and the contact simultaneously; The numbering plate can be distinguished numbering to contact accurately, prevents the appearance of the problem of wrong line.
