Abstract

To provide a base electrical connector ensuring a highly reliable electrical connection. A recessed part is provided in a lower part (2c) of a pin (2), and a bottom face 6 of the recessed part is formed on an inclined surface. The pin (2) is slidably arranged in a sleeve (10), and is energized upwardly by a coil spring (14) in the sleeve (10). The inclined bottom face (6) biases the pin (2) in the direction of the arrow B, and the sleeve (10) is laterally pressed to establish a reliable electrical connection between the sleeve (10) and the pin (2).

Description

Electric connector

But the present invention relates to the electric connector on a kind of mounting panel, it has a pin made from metal stock integral body and is used to push the helical spring of this pin.

Shown in Figure 4 is the connector 100 that a pin 104 is arranged, and pin 104 is slidably mounted in the sleeve 102, is promoted by helical spring 106, so that pin is released from sleeve 102.Helical spring 106 curves " ㄑ " shape, and is placed sleeve 102 forcibly, is used for laterally or side direction pushing pin 104, makes it to head on sleeve 102, therefore, has improved the reliability of electrical connection between pin 104 and the sleeve 102.

In above-mentioned traditional connector 100, when pin 104 slided in sleeve 102, the use of " ㄑ " shape helical spring 106 had increased the possibility that the laterally projecting part of helical spring 106 is run into the inner surface of sleeve 102.In this case, the coating on the inner surface of sleeve 102 is drawn by wiping and has been reduced the reliability that is electrically connected.

" ㄑ " shape helical spring 106 has increased expense.In addition, " ㄑ " shape helical spring generally must be straight before in being installed to sleeve 102, and this makes fitting operation difficulty and reduced productivity ratio.

Consider above problem, but purpose of the present invention just provides the electric connector on the high mounting panel of a kind of reliability of electrical connection.

But another object of the present invention provide a kind of be easy to install and the mounting panel of low profile design on electric connector.

But comprise: place insulation shell to have the metal sleeve of bottom according to the electric connector on the mounting panel of the present invention, a pin of being installed to slidably in the described sleeve, one places described sleeve to be used for along the helical spring of the direction pushing pin bottom of releasing pin from described sleeve, its feature is that pin forms groove and skewed surface on its edge, bottom with above-mentioned direction, and skewed surface and helical spring push pin along the direction with above-mentioned direction deflection together.

In addition, but comprise: place insulation shell to have the metal sleeve of bottom according to the electric connector on the mounting panel of the present invention, a pin of being installed to slidably in the described sleeve, one places described sleeve to be used for along the helical spring of the direction pushing pin bottom of releasing pin from described sleeve, the bottom that is characterized in sleeve be skewed surface with the support helix spring, make helical spring along and the direction of above-mentioned direction deflection pushing pin.

Now, but be described with reference to the drawings according to the electric connector on the mounting panel of the present invention (being designated hereinafter simply as connector).

But Fig. 1 is the profile according to first embodiment of the electric connector on the mounting panel of the present invention;

Fig. 2 is the cutaway view along the II-II line in the connector shown in Figure 1;

Fig. 3 is the profile according to connector second embodiment of the present invention;

Fig. 4 is the profile of traditional connector.

Shown in Figure 1 is the cutaway view of the first embodiment of the present invention.Fig. 2 is the cutaway view of the connector of II-II along the line among Fig. 1.But, be noted that helical spring is not included in.

With reference to figure 1, the pin 2 of connector 1 has constituted the contact portion that contacts with the contact (Fig. 1 is not shown) of coupling.Pin 2 is made into integration by metal base by forging (forging machine) and barrel polishing.Head portion 2a makes the part of the sphere of 0.45mm with barrel polishing.Mid portion 2b is roughly cylindric, is thereafter to divide 2c with the large diameter bottom that step (or transition) part 2d forms.Pin 2 is to be made into integration with traditional forging manufacturing technique.Pin 2 forms groove 4 in bottom 2c punching press.Notice that the basal surface 6 of groove 4 is tilt (not being 90 degree) with respect to the axle Z-Z at the center of extend through connector 1.Included angle A between the normal of basal surface 6 and central axis Z-Z is 5-20 ° scope, preferably 15 °.For example, the size of pin 2 is about 3mm height, and base diameter is 1.3mm, and the degree of depth of groove 4 is 0.5mm.

Sleeve 12 is integrally formed by metal stock, and pin construction opening 12 is that cutting forms.The top 10a of sleeve 10 rolls up inwards, in case shotpin 2 comes out.What place pin construction opening 12 is helical spring 14 between basal surface 18 and pin 2, and helical spring 14 upwards pushes pin 2.Skewed surface 6 Elastic Contact of helical spring 14 and pin 2.Therefore, along the B direction pin 2 that baroclines.Then, by transversal thrust, therefore, guarantee the reliable electrical connection between sleeve 10 and the pin 2 at the bottom 2c of sleeve 10 inner peg 2.The cylinder body part of sleeve 10 is put into the hole 32 of insulation shell 30 forcibly, and it is fixed in the hole 32.Sleeve 10 forms the part 16 that stretches out by cutting or punching press, is used for carrying out mounted on surface at (not shown) on the circuit board or on the substrate.

Fig. 2 is the cutaway view along the II-II line among Fig. 1, and it clearly show that the annular shape of the groove 4 of pin 2.Among Fig. 2, many sleeves 10 vertically, promptly the directions X of drawing is placed with predetermined interval.But, in Fig. 2, only show a sleeve.

Then with reference to figure 3.Fig. 3 shows the second embodiment of the present invention.Note, in Fig. 3, used with initial identical label and come element similar in the representative graph 1.Connector 1 among Fig. 3 ' and Fig. 1 in the main distinction of connector 1 comprise pin 2 ' basal surface 6 ' with axle Z '-Z ' perpendicular (not being to tilt), sleeve 10 ' inner bottom surface 18 ' tilt with a Z '-Z ' (normal).Helical spring can be the helical spring 14 of the connector 1 among Fig. 1.Because the bottom and the basal surface 18 ' Elastic Contact of helical spring 14,, baroclined in the direction of arrow C by 2 ' time of basal surface 18 ' promotion pin.As a result, pin 2 ' basal surface 2C ' transversal thrust sleeve 10 ' inner surface, guarantee to be electrically connected.

Although described the preferred embodiments of the present invention, the present invention should not be limited to such specific embodiment, can make various modifications under the situation that does not break away from the present invention's design.

For example, sleeve can be the through-hole type in the through hole that is inserted in the circuit board.In a second embodiment, though need not provide pin 2 ' the bottom in groove 4 ' and still have identical advantage.In addition, the metal sleeve in each embodiment can be made with punching press, and forms metallic plate.Helical spring can be the bucket formula that smaller diameter is arranged at two ends.

Fluted and the groove in the bottom of pin has the lip-deep connector of the wedged bottom that is pushed by helical spring to have following advantage: make the helical spring that is generally straight barocline pin to obtain the reliable electrical connection between sleeve and the pin.Simultaneously, the groove in the pin helps the height that equals the degree of depth of groove reduced in size.This means using the common straight helical spring while, can improve the reliability of electrical connection, and will hang down the connector profile.In addition, also make installation easily.

The bottom of sleeve is the connector of wedged bottom, wedged bottom and helical spring Elastic Contact, and its advantage is as follows: the common straight helical spring pin that can barocline, to set up the reliable electrical connection between sleeve and the pin.In addition, also be easy to install.
