Abstract

The utility model provides the new structure of a probe sleeve pipe. The outer edge of one end of the sleeve pipe is provided with a flange and the diameter of the other end part is a little contracted to form a wire winding section whose middle section is annularly provided with a plurality of annular grooves whose inner parts are used for inlaying conductor wires. The part close to the tail end of the sleeve pipe is provided with a convex blocking part forming a cone block shape to block the sliding disconnection of the conducting wires. The sleeve pipe is punched into a semi-finished product by a metal material board according to the appearance of the sleeve pipe, the annular grooves and the blocking part. The semi-finished product is rolled along the axial direction to enable the two side edges of the semi-finished product to be combined into the sleeve pipe forming a circular pipe shape in butt joint.

Description

Probe sleeve pipe new construction

The utility model relates to a kind of probe, particularly a kind of probe assembly.

The one-piece construction of conventional probe as shown in Figure 1, by the probe 2 of planting in the sleeve pipe 1.Sleeve pipe 1 is formed by a body 11 and a roll 12 cramping windings; One end outer rim of body 11 is provided with a bulge loop 111, and in the jack that is fixed on tool, the other end is established the neck tube 112 of a undergauge, and grafting rolls 12 in the neck tube 112 give cramping with neck tube 112 and roll 13 and fix.Sleeve pipe 1 traditional user makes with metal tube material (copper pipe) system of taking out or metal blank (copper coin) deep-draw, and particularly plate is made in deep-draw needs the multiple-die press punching out 8 to 24 times more than, and manufacture process is slow, the cost height, and damage plate easily.And roll 12 is to twine on it for lead 121, yet its smooth exterior surface makes lead 121 can't obtain good location, is not easy to twine and come off easily again, causes conductive effect bad; And sleeve pipe 1 is combined by two bodies, and its conductive effect is also undesirable.

The purpose of this utility model is that a kind of probe sleeve pipe new construction will be provided, and it can be located and not come off, and keeps the good conductive effect, and the semi-manufacture fraction defective reduces in the manufacture process, and manufacturing cost reduces.

Utility model is achieved in that at the other end of sleeve pipe undergauge and extends to form a coiling section, the middle section of coiling section is provided with a solidus portion, the part bare wire of lead termination and envelope curve twine in regular turn and fix on it, are provided with one in the position of the contiguous solidus of coiling section near caudal end part portion and prevent the stop section that lead falls to take off.

The utility model is because sleeve pipe and coiling section are one continuity structure, the two-piece structure that body that conductive effect is more traditional and roll cramping engage is good, lead mat solidus portion location, and being combined with the stop section, lead can not come off, and keeps the favorable conductive effect, simultaneously, sleeve pipe Production Time can shorten, and the semi-manufacture fraction defective reduces in the manufacture process, thereby reduces manufacturing cost.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a conventional probe structure axonometric exploded view.

Fig. 2 is the utility model probe sleeve pipe new construction axonometric drawing.

Fig. 3 is the utility model enforcement figure.

Fig. 4 is the utility model probe sleeve pipe semi-manufacture side views.

With reference to Fig. 2,3, probe structure is a sleeve pipe 20 interpolations one probes 30; Sleeve pipe 20 is a hollow body, one end close end outer rim is provided with a flange 21, the other end slightly undergauge extends to form a coiling section 22, and the middle section of coiling section 22 is provided with a solidus portion 23, can allow the part bare wire envelope curve of lead 24 terminations twine in regular turn and fixes on it; Solidus portion 23 mainly establishes several annular grooves 231 at coiling section 22 outer rim rings, makes lead 24 around embedding in it; Respectively there is the bigger stop section of an external diameter 25,26 at the two ends of solidus portion 23, will be arranged in lead 24 in the solidus portion 23 and be limited to the zone and avoid coming off; Wherein the stop section 26 of nearly sleeve pipe 20 tail ends is block for awl, and it has a plane and is used for block lead 24 with respect to this solidus portion 23.

Impose axial force sleeve pipe 20 is pressed into circuit board along in the default jack 41 of tool, sleeve pipe 20 closely cooperates by the internal diameter garden formation of flange 21 with jack 31, and sleeve pipe 20 can be fixed on the jack 41, and probe 30 can insert in the sleeve pipe 20; This lead 24 and especially prevents lead 24 slippages by the stop section 26 of lower position in investing annular groove 231.

With reference to Fig. 4, it is the semi-manufacture side view of sleeve pipe 20, the making of sleeve pipe 20 mainly places one to have on the counterdie of sleeve pipe 20 product design rags a metal (copper) flitch 50, patrix has and the corresponding rag of counterdie rag, continuous punching press through 2-4 time, promptly form the face shaping of sleeve pipe 20 and coiling section 22 on the flitch 50, its surface also has the recessed limit of flange 21, annular groove 231, awl piece shape stop section 26; Mode can be held in the mouth system majority sleeve pipe 20 semi-manufacture on the same metal flitch 50 according to this; Calculate sleeve pipe 20 circumference according to sleeve pipe 20 overall diameters, downcut sleeve pipe 20 semi-manufacture according to this, sleeve pipe 20 semi-manufacture are axially rolled volume, make relatively also imperceptible seam 27 of formation of driving fit of half-finished dual-side, promptly finish sleeve pipe 20 finished products; It is tubular that to be sleeve pipe 20 roll volume dual-side connect synthetic garden by sleeve pipe 20 profiles, solidus portion 23, stop section 25,26 along its direction of principal axis by a metal flitch 50.
