The terminal has comparatively high structural strength and comparatively long service life and is convenient to produce and install.

Description

Splicing ear

Technical field

The utility model relates to a kind of splicing ear, refers to a kind of splicing ear of making, assembling of being easy to especially, and this terminal has higher structural strength and long useful life.

Background technology

As shown in Figure 4, general known splicing ear is made up of a sleeve 50 and a contact site 51, between this sleeve and contact site, be provided with a spring 52, and the two ends of this sleeve 50 have a sealing surface 502 and an opening 501 respectively, this sealing surface 502 of this splicing ear is welded on the circuit board, contacts with the electrode of externally hanging battery by contact site 51; When assembling this splicing ear, put into spring 52 earlier, again contact site 51 is inserted from the opening 501 of sleeve 50 1 ends afterwards, last again with opening 501 usefulness instruments (or anchor clamps) clamping of these sleeve 50 1 ends, make this opening 501 riveteds.

Though above-mentioned splicing ear can contact with the electrode of externally hanging battery for being welded on the circuit board, but because this splicing ear volume is less, and when assembling, must impose the operation of clamping to the opening 501 of these sleeve 50 1 ends with instrument (or anchor clamps), with these opening 501 riveteds, so be difficult to control its dynamics during because of tool using (or anchor clamps) or the application of force improper, and making easily, press from both sides terminal bad during assembling, or the askew phenomenon of generation riveting, cause the increase of percent defective, moreover this instrument (or anchor clamps) only imposes a riveted operation that clamps to the opening 501 of this sleeve one end, therefore, this is concerning making the contact site 51 of reciprocating action for a long time, very easily use after a period of time because of this terminal, causing originally, the opening 501 of riveted is strutted, and make this terminal that the contact of externally hanging battery electrode can't be provided, and therefore, the above-mentioned known splicing ear and the needs of realistic use well.

The utility model content

Main purpose of the present utility model is to make splicing ear to be easier to make, assemble; And this terminal has higher structural strength and long useful life.

For realizing above-mentioned purpose, the utility model provides a kind of splicing ear, this terminal system is in order to be disposed on the circuit board, electrode contact for externally hanging battery is used, this terminal comprises: a body, and this body has a storage tank, and the two ends of this body offer first opening and second opening that runs through this storage tank respectively, and this first opening is provided with an annular stop portion, makes an end of this body be a state that shrinks gradually; An end and part that one contact site, this contact site are configured in above-mentioned body storage tank expose to this first opening, and an end of this contact site is provided with a stopper section, and this stopper section is corresponding to the medial margin of above-mentioned limiting section; One pin member, this pin member are arranged on second opening part of above-mentioned body; One elastic parts, this elastic parts is arranged in the storage tank of above-mentioned body, and is limited between this contact site and the pin member, an end roof pressure of this elastic parts on an end face of contact site, the other end then roof pressure on an end face of pin member.

Embodiment

See also Fig. 1～Fig. 3, be respectively three-dimensional appearance schematic diagram of the present utility model, perspective exploded view of the present utility model and profile status schematic diagram of the present utility model.As shown in the figure: the utility model provides a kind of splicing ear, this terminal is used to be configured in circuit board, for contacting (not shown) with the electrode of externally hanging battery, this splicing ear is made up of a body 1, a contact site 2, a pin member 3 and an elastic parts 4, can make this terminal be easier to make, assemble, and can increase the structural strength of this terminal, prolong the useful life of this terminal.

Above-mentioned body 1 has a storage tank 11, and the two ends of this body 1 systems offers first opening 111 and second opening 112 that runs through this storage tank 11 respectively, and these first opening, 111 place's annulars are provided with a limiting section 113, make an end of this body 1 slightly be a form of shrinking gradually; This contact site 2 is configured in an end of above-mentioned body 1 storage tank 11, and part exposes to outside this first opening 111, one distolateral edge of this contact site 2 is provided with a stopper section 21, and this stopper section 21 makes this contact site 2 be limited in first opening, 111 places of storage tank 11 1 ends corresponding to the medial margin setting of above-mentioned limiting section 113; This pin member 3 is arranged on second opening, 112 places of above-mentioned body 1, and an end of this pin member 3 is a state that shrinks gradually, makes this pin member 3 be easy to import in second opening 112;

This elastic parts 4 is arranged in the storage tank 11 of above-mentioned body 1, and it is spacing between this contact site 2 and pin member 3, and an end roof pressure of this elastic parts 4 is on an end face of contact site 2, the other end then roof pressure on an end face of pin member 3, make this contact site 2 do back and forth flexible operation by this elastic parts 4, and, these contact site 2 unlikely first openings 111 from body 1 are broken away from by the stopper section 21 of this contact site 2 and the restriction of the limiting section 113 of body 1 first opening 111.

And when this splicing ear of assembling, only need this contact site 2 is inserted from second opening 112 of body 1 storage tank 11, and make this contact site 2 form spacing because of limiting section 113 medial margins of the stopper section 21 and first opening 111, spacing and the part of this contact site 2 is exposed to outside first opening 111 of storage tank 11, insert elastic parts 4 afterwards again, an end roof pressure that makes this elastic parts 4 is on an end face of contact site 2, last second opening, 112 places of body storage tank 11 of again this pin member 3 being inserted, utilize this pin member 3 to be the shape of shrinking gradually, the one end is imported in second opening 112, utilize the other end of these pin member 3 broads again, make this pin member 3 be fixed on second opening, 112 places of body 1 storage tank 11, and stopping up second opening 112, the other end roof pressure that makes this elastic parts 4 is on an end face of pin member 3.So finish the assembling process of this terminal, make this splicing ear be easier to make, assemble, and can increase the structural strength of this terminal, and then prolong the useful life of this terminal.
