Description

Battery connector

Technical field

The utility model relates to a kind of battery connector, relates in particular to a kind of distribution density of conducting terminal, effective battery connector that promotes the yield that electrically connects of reducing.

Background technology

As depicted in figs. 1 and 2, generally be applied to electronic installation, as the battery connector in the mobile phone 1, it is used for making 31 of the plurality of conducting strips of the side of a circuit board 2 and a battery 3 to electrically connect mutually.This battery connector 1 includes one and has some insulation shells 11 of the storage tanks 111 of arrangement in the same way, and some conducting terminals 12 that is installed in respectively in these storage tanks 111.Each conducting terminal 12 has a junction 121 that electrically connects with circuit board 2, and one protrude in outside the set storage tank 111 of insulation shell 11, and the contact site 122 that electrically connects with the conducting strip 31 of battery 3, these contact sites 122 are spaced along a virtual straight line 33.

See also Fig. 2,, also be forced to dwindle, to reach the effect of effectively utilizing the space because the miniaturization of electronic installation makes the electronic building brick of battery connector 1 and so on be subject to the interior space of electronic installation.But also because battery connector 1 dimension reduction, make the spacing of 122 of contact sites of these conducting terminals 12 to enlarge arbitrarily, cause its distribution density to increase.Relative, what also make the conducting strip 31 that is subject to these contact site 122 overall distribution air line distances allows that width with area thereby dwindle, simultaneously, makes both electrically connect when using, and the corresponding range of allowable error that effectively contacts is dwindled.As long as the tolerance that cooperatively interacts between parts is accurate inadequately, or because of being shaken or when making for a long time the tolerance expansion that cooperatively interacts between parts, the capital causes these conducting strips 31 can't aim at the corresponding with it contact site 122 of contact accurately, so, it is bad promptly can to produce electric connection, and make the user must open the housing of cell apparatus again and again, and adjust the orientation of battery 3, perhaps make electronic installation just in use lose its function suddenly.

More than explanation is to be example with the battery connector with three conducting terminals, certainly, according to different designs, still have and have four, the battery connector of five, six or more conducting terminals, but because all neat arrangement being aligned of contact site of these conducting terminals, it all has above-mentioned shortcoming, and number is many more serious more.

See also Fig. 3, it is No. the 91207217th, Taiwan patent application " battery connector of terminal dislocation arrangement ", and this battery connector 4 comprises: an insulation shell 41 has at least three storage tanks 43; And at least three conducting terminals 42, these conducting terminals 42 are installed on respectively in these storage tanks 43, each conducting terminal 42 has a junction 421 that electrically connects with this circuit board 5, and one protrude in pairing storage tank 43 contact site 422 outer and that electrically connect with the conducting strip 61 of this battery 6, the contact site 422 of these conducting terminals 42 is the alternating expression arranged distribution, to reduce the distribution density of these contact sites 422, the area of the conducting strip 61 on the increase that simultaneously more can be relative and the battery 6 of its electric connection, make 61 of these contact sites 422 and corresponding conducting strips, the site error of allowing when connecting increases, and then promotes the yield that electrically connects.Yet, because these conducting terminals 42 are for being the microscler lamellar body of pressure-bearing type, it takies bigger area when being arranged on the circuit board 5, and when the contact site 422 of conducting terminal 42 electrically connects with the conducting strip of battery 6 61, contact site 422 can produce horizontal swing, so need to reserve bigger activity space, therefore be difficult to the more distribution density of these contact sites 422 of reduction of a progress, and increased the site error of allowing when connecting.

Summary of the invention

The purpose of this utility model is to provide a kind of battery connector, it is the distribution density of the reduction conducting terminal of a progress more, more can effectively increase simultaneously the conducting strip area on the battery with its electric connection, make between conducting terminal and the corresponding conducting strip, the site error of allowing when connecting increases, and then the yield of more effective lifting electric connection.

The utility model provides a kind of battery connector, it is applicable to be installed in this circuit board electrically is connected with a battery that this battery connector comprises: one has at least three through hole insulation shells, at least three contact element and at least three elastic components that are installed in respectively in these through holes that are installed on respectively in these through holes; These contact elements are the alternating expression arranged distribution; These elastic components this contact element elasticity of contact respectively stretch out this insulation shell, and these contact elements are crimped on the conducting strip of battery.

The utility model is the distribution density of the reduction conducting terminal of a progress more, makes between conducting terminal and corresponding conducting strip, and the site error of allowing when connecting increases, and effectively promotes the yield of electric connection.
