Abstract
The utility model discloses an electric pen used in electronic instruments. For overcoming the inconvenience brought by the fixed structure of the electrical contact head of an ordinary electric pen, an electric pen whose electrical contact head can move lengthways is provided. According to use requirements, the pen head can be twisted by fingers, thus, the threads in the interior of the pen head and the threads on the electrical contact head are mutually inosculated to control the lengthways movement of the electrical contact head and to alter the length of the electrical contact head extending from the pen head. The other end of the electrical contact head is provided with a connecting spring which is mutually connected with a conductive guide rail at the inner wall of a watch bar, then a guide rail slot leads out conductor wires which is mutually connected with a buffer spring on a circuit board and a jack for being externally connected with test wires. The external lead-out wire of the electric pen is led out at the other end of the buffer spring.
Description
The utility model relates to a kind of hand prod of electronic device, more particularly, is the test pencil that is made of test pencil shell, electrical contact and outer lead.
The employed test pencil of people is exactly this structure at present, mainly is made up of test pencil shell and electrical contact.In surveying work, in order to prevent, need electrical contact short sometimes by the caused short circuit accident of the electrical contact of test pencil; Sometimes in order to touch the test point at dark some positions, require electrical contact long again, and the length of the electrical contact of present this test pencil is fixed, and can not arbitrarily vertically move, thereby make troubles to work.Also have a bit, at work, often need draw a p-wire in addition on test pencil, so that link simultaneously on other testing tool, but this test pencil is difficult for finishing this function again.
The purpose of this utility model provides a kind of test pencil, and the length of its electrical contact can be adjusted, and external p-wire is very convenient again.
For finishing above-mentioned task, solution of the present utility model is that the electrical contact of test pencil is made adjustable structure, by the mechanism of reconciliation statement nib portion, reaches the purpose of regulating electrical contact length.Near the place of afterbody, a patch jack is arranged at test pencil, when need being convenient to, drawing outward and connect p-wire.This test pencil is difficult for broken string in order to make outer extension line, and the buffering termination also is housed.
Because this test pencil has adopted above-mentioned measure, so it is convenient that test pencil is used.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a three-dimensional cutaway view of the present utility model.
In Fig. 1, the test pencil profile is circular, and electrical contact (1) is contained in the mesopore of test pencil.Screw thread (3) is arranged on electrical contact (1), limited block (5) is arranged at the middle part of electrical contact (1) in order to limit the distance that electrical contact vertically moves.Nib (2) and spacer (4) are installed on the table rod (10) by web member (6), and nib (2) is free to rotate.On nib (2) internal diameter screw thread is arranged also, cooperate screw thread (3) the control electrical contact on the electrical contact (1) to vertically move.On the other end of electrical contact (1), connection spring (7) is housed with screw (9), cooperate the metal guide rail (8) on table rod (10) endoporus two side, may command electrical contact (1) can only lengthwise movement and can not be rotated, and links on the screw (14) of web joint (13) by lead (11) simultaneously.Go up jack (16) and extension line screw (15) in addition at web joint (13).In extension line screw (15).Buffer spring (17) is housed on extension line screw (15), and extension line (19) is welded on the buffer spring (17).For the easy accessibility of test pencil, test pencil has table rod (10), and grafting links to each other with test pencil tail cap (18), simultaneously, cooperates the via hole (12) of jack (16) in addition on table rod (10) and test pencil tail cap (18).
Claims (3)
1, a kind of test pencil of forming by test pencil shell and electrical contact, lead-in wire, it is characterized in that: also be equipped with on test pencil head and the electrical contact to make the regulating device that electrical contact is vertically moved also is housed on the electrical contact, the other end of electrical contact has contact device to contact with the conductive trough of the excellent inwall of table, and conductive trough links to each other with a buffer spring and a jack.
2, test pencil according to claim 1 is characterized in that: vertically move regulating device and be the screw thread (3) on the electrical contact (1) and the internal thread of nib (2) and match, nib (2) is installed on the table excellent (10) by web member (4).
3, test pencil according to claim 1 is characterized in that: contact device is for connecting spring (7).
