Description
Technical field
The present invention relates to a kind of connector of electrical connection, particularly relate to a kind of multi-contact electrode jack.
Background technology
The electrode jack that present video camera battery etc. adopt, just simple circular hole, after electrode electrode insertion jack during use on video camera, the tube wall that the transmission of electric current mainly relies on the resilient contact of electrode both sides to touch electrode jack forms galvanic circle.The mode Problems existing of this unidirectional contact conductive is that the plug for a long time of electrode and jack can produce wearing and tearing, cause the contact between the contact of electrode and the contact point of battery jack gradually by tightly fluffing, easily there is the problem that electrode loose contact and contact resistance become large, because contact resistance becomes large, when battery big current is powered, electrode and jack very easily generate heat, hot, there is the bad phenomenon such as ablation distortion or power-off, time serious, even can produce other safety problems.And, along with the development of high definition technology, high definition, ultra high-definition video camera are used increasingly, these high definitions, ultra high-definition video camera all need the battery of big current to power, generating heat easily appears when powering to video camera big current because contact area is less in the electrode of traditional unilateal conduction contact, hot, the even situation such as ablation.
Cause contacting the problem fluffed for solution electrode jack repeatedly plugs, the application of CN102522647A provides a kind of spring-ring type inserting hole, comprise the jack body being provided with circular pin hole, the inwall of described pin holes is provided with the cannelure of U-shaped profile, spiral elastic ring is provided with in cannelure, the internal diameter of described spiral elastic ring is less than the aperture of pin holes, and the height of spiral elastic ring is consistent with the width of cannelure, and the helical spring forming spiral elastic ring is oblique spring.When inserting pin holes with the pin on the contact pin of jack adaptation, near spiral elastic ring internal side diameter helical spring will with pin close contact, made every effort to promote by the radial elastic of the oblique spring coming from special construction and make pin and pin holes close contact.This oblique spring is a kind of spring of special construction, be the size of helical angle be periodically variable spring, form between all single-coil spring lines of this spring and the cross section of this spring and there is an inclination angle, and the same direction of all single-coil spring alignments tilts, the spring with this structure can produce elastic force in a certain radial direction.CN101958479A provides a kind of Zero insertion connector jack adapting to different plug, it comprises the contact assembly, elastic body, the locking mechanism that form jack, described contact assembly comprises at least two contacts, can relatively close or open between contact, described elastic body acts on contact assembly and makes to produce pressure between contact, and locking mechanism acts on contact assembly and makes can relatively close or open between contact.This application installs elastic body in the side of contact, and plug inserts between two contacts in jack, and the elastic force of the elastic body of contact side makes plug and jack close contact.This technical scheme installs elastic body additional in contact side, and need the diameter strengthening jack itself, jack shape is thick.CN202103209U provides a kind of jack contact, comprise the jack body that leading portion is cylindrical body, the periphery wall of the leading portion of jack body has more than one annular groove is set, the leading portion of jack body has the plural shaft orientation opening groove being divided into the segmentation pawl overhang forward that the plasticity when plugging together with adaptive contact pin is opened outward, shaft orientation opening groove runs through and arranges annular groove, arrange in annular groove be arranged with keep the inside/outside diameter size of jack body leading portion can the locking hoop that actuates of radial elastic.This utility model, by jack body arranged outside annular groove, is blocked in annular groove and is established locking hoop, kept the inside/outside diameter size of jack, this utility model complex structure by locking hoop, manufactures and install all comparatively inconvenience.
Summary of the invention
The invention provides a kind of multi-contact electrode jack, the structure solving ubiquitous unidirectional contact conductive in existing video camera battery product with a kind of structure of multidirectional contact conductive easily makes electrode occur the cell damage that the problem of loose contact and electrode or jack ablation are brought or even safety problem.
Multi-contact electrode jack provided by the present invention, comprise conductive shell, it is characterized in that: bottom described conductive shell, be provided with spring, the upper end of described spring is provided with conductive slider moving up and down, and the inwall of described conductive shell is provided with the spacing preiection come off in conductive shell for limiting conductive slider.After electrode electrode insertion jack, electrode tip contacts with conductive slider, and along with the insertion of electrode, spring is compressed, and the elastic force of spring makes electrode and conductive slider close contact.Multi-contact electrode jack provided by the present invention, except the side contacts of two transverse directions of existing ordinary electrode jack, adds longitudinal top of electrodes contact-making surface.
Further, the longitudinal section of described conductive slider is rectangle or T-shaped; The top end face of conductive slider is arranged at the below of spacing preiection.
Further, the longitudinal section of described conductive slider is inverted T-shaped, and the bottom lateral protrusions of conductive slider is arranged at the below of spacing preiection.
Further, the longitudinal section of described conductive slider is " work " font, and described spacing preiection is positioned at the lateral groove of conductive slider.The conductive slider of " work " character form structure is comparatively firm in conductive shell, there will not be crooked when electrode inserts.
Further, the upper end of described conductive slider and the contact-making surface of electrode can be arranged to concave surface or plane.When the tip designs of electrode becomes arc outwardly, the contact-making surface with the conductive slider of concave surface and electrode is larger.
Further, the spacing preiection on the inwall of conductive shell is the protruding or circular projection of multiple spot.
The present invention is on the basis of the side contacts of two transverse directions of existing ordinary electrode jack, add longitudinal top of electrodes contact-making surface, and owing to being equipped with spring bottom conductive shell, the pretightning force of spring makes conductive slider fully contact with electrode tip, can effectively avoid electrode to plug for a long time causing wearing and tearing to contact and the problem of electrode loose contact brought; In addition, the electrode contacts of this longitudinal direction of increase, can effectively reduce the contact resistance of Electrode connection, thus reduces the electrode caloric value in using, and extends electrode life.Inside provided by the invention is with the multi-contact electrode jack of telescopic resilient contact, solve electrode and electrode jack because Long-Time Service easily exists the problem of loose contact and electrode erosion, the electrode loose contact problem existed after efficiently avoid Long-Time Service, also reduce the risk of electrode erosion simultaneously, contribute to extending electrode life, also make product structure more simple, easier processing and manufacturing simultaneously.
