Abstract

The utility model discloses a high-frequency electrosurgical unit used hand-operated electrosurgical pencil plug with adjustable pin distance. The plug comprises a housing, a core, a plurality of electrical pins and a plurality of wires electrically connected with tail ends of the electrical pins. The core is mounted inside the housing. The plurality of electrical pins are plugged in the core. The housing is provided with pin holes matching with the electrical pins, and heads of the electrical pins pass through the pin holes. The core is made of elastic material. The area of the pin hole on the housing is larger than the cross section of the head of the electrical pin. According to the utility model, the distance between pins can be slightly adjusted, so that the high-frequency electrosurgical pencil can be plugged easily with good plugging contact, thereby improving the universality of the high-frequency electrosurgical pencil.

Description

The adjustable electric knife of contact spacing hand controlled electrotome penholder head

Technical field

The utility model relates to the adjustable electric knife of a kind of contact spacing with hand controlled electrotome penholder head, is mainly used on high frequency hand controlled electrotome pen, and be parts of high frequency hand controlled electrotome pen, be used for a high frequency hand controlled electrotome pen and high frequency electro surgical unit to be electrically connected.

Background technology

At present, on market, the brand of electric knife is numerous, because the manual socket of electric knife does not have unified industry standard, cause the different brands electric knife the spacing of 3 jacks between mutually of manual power stage all not quite identical.The spacing of the contact pin of the plug of electric knife in the market is all fixing, is all generally to coordinate the electric knife that our unit produces to use, and inserts the electric knife of other brands, is not that to insert not advance be exactly to be difficult to after inserting pull out.Make like this doctor find the slotting socket that does not advance electric knife of plug of high-frequency electrotome pen when using high-frequency electrotome pen before the operation of being everlasting, affect carrying out smoothly of operation.According to market survey at present in the manual receptacle sockets spacing deviation of electric knife in ± 1.5mm, use so the adjustable hand controlled electrotome pen of contact spacing can overcome this situation fully, its contact spacing can be freely movable within the specific limits, can regulate according to jack interval in the time of the high-frequency electrotome pen plug-socket, the plug that makes high-frequency electrotome pen all very laborsaving and plug and jack contact very good.

Summary of the invention

Technical problem to be solved in the utility model is the defective that overcomes prior art, the adjustable electric knife of a kind of contact spacing hand controlled electrotome penholder head is provided, spacing between its contact pin can be finely tuned, make that the plug of high-frequency electrotome pen is more laborsaving and the contact of pegging graft is good, improved the versatility of high-frequency electrotome pen.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: the adjustable electric knife of a kind of contact spacing hand controlled electrotome penholder head, comprise shell, inner core and a plurality of electrical contact pin and the many wires that are electrically connected with electrical contact pin tail end, inner core is installed in the enclosure, a plurality of electrical contact pins are inserted in inner core, have the pin holes that matches with electrical contact pin on shell, electrically the head of contact pin passes pin holes, described inner core is made by elastomeric material, and the hole face of the pin holes on described shell is larger than the cross section of electrical pin head.

Further, described shell is formed by plug lower house and the heat seal of plug upper shell.

Further, described inner core is comprised of inner core under inner core on plug and plug.

Further, described pin holes is ellipsoidal structure.

Further, an end of described multiple conducting wires concentrates in together, and passes from the afterbody wire hole of shell.

Further, described electrical contact pin has three, and described pin holes also has three.

After having adopted technique scheme; Inner core is owing to adopting the elastomeric material injection mo(u)lding; The hole face of the pin holes on shell is larger than the cross section of electrical pin head; Cement admittedly when the plug assembled formation and shell after; Electrically contact pin can utilize the elastomeric elasticity of inner core that certain displacement can be arranged in pin holes; So just make the spacing between electrical contact pin can left and right adjusting; After extracting this plug; The elastic reaction of inner core can reset to original position to electrical contact pin again; It can coordinate the electric knife of multi-brand to use; The generation of having avoided plug plug difficulty or can not having used; The versatility of high-frequency electrotome pen is improved.

Description of drawings

Fig. 1 is the structural representation that the adjustable electric knife of contact spacing of the present utility model is used hand controlled electrotome penholder head.

Embodiment

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,

As shown in Figure 1, the adjustable electric knife of a kind of contact spacing hand controlled electrotome penholder head, comprise shell 16, inner core 24 and a plurality of electrical contact pin 5 and the many wires 3 that are electrically connected with electrical contact pin 5 tail ends, inner core 24 is arranged in shell 16, a plurality of electrical contact pins 5 are inserted in inner core 24, have the pin holes 16-1 that matches with electrical contact pin 5 on shell 16, electrically the head of contact pin 5 passes pin holes 16-1, inner core 24 is made by elastomeric material, and the hole face of the pin holes 16-1 on shell 16 is larger than the cross section of electrical contact pin 5 heads.

Shell 16 is by plug lower house 1 and plug upper shell 6 is gluing forms.

Inner core 24 is comprised of inner core 2 under inner core on plug 4 and plug.

Pin holes 16-1 is ellipsoidal structure.

One end of multiple conducting wires 3 concentrates in together, and passes from the afterbody wire hole of shell 16.

Electrically contact pin 5 has three, and pin holes 16-1 also has three, but is not limited to this.

Operation principle of the present utility model is as follows:

Inner core 24 is owing to adopting the elastomeric material injection mo(u)lding; The hole face of pin holes 16-1 on shell 16 is larger than the cross section of electrical contact pin 5 heads; When the plug assembled formation and after shell 16 being cemented admittedly; Electrically contact pin 5 can utilize the elastomeric elasticity of inner core 24 that certain displacement can be arranged in pin holes 16-1; So just make the spacing between electrical contact pin 5 can left and right adjusting; After extracting this plug; The elastic reaction of inner core 24 can reset to original position to electrical contact pin 5 again; It can coordinate the electric knife of multi-brand to use; The generation of having avoided plug plug difficulty or can not having used; The versatility of high-frequency electrotome pen is improved.
