Description

Be suitable for direct bonding flexible circuit jockey on the machine plate

Technical field

The invention relates to a kind of arrangements of electric connection, refers in particular to a kind of direct bonding flexible circuit (FPC) jockey on the machine plate that is suitable for.

Background technology

Now, progress along with science and technology, people are to using the demand of appliance and electronic from the unification function, to transfer to various integrated functionality in production and life, also by the intelligent mobile phone of current (collection: conversation, online, scanning and take a picture, and remote control is controlled the function such as household electrical appliances and is the whole body), replaced with mobile phone as the early stage conversation of being absorbed in.

yet, when the function of electronic product increases, its product component also can increase naturally, so intangibly also taken the limited space of electronic product, desired " light with pursuit " portable ", thin, short, little " consumption concept incompatible, for example: lithium ion battery connector of the prior art, sim card connector etc., mostly be take the glue core as body electric terminal is fixed, be assembled in mobile phone by the form of pegging graft or weld again, this kind multicompartment, the assembling modes of many welding have taken not only that mobile phone is limited to have living space, and be not easy to make operation, be electrically connected simultaneously effect also not good, both consume material costs, also labor intensive operating cost.

Summary of the invention

For solving above-mentioned technological deficiency, the main purpose of the invention is to provide a kind of direct bonding flexible circuit (FPC) jockey on the machine plate that is suitable for, this jockey can effectively reduce taking up room in mobile phone, and also convenient batch is made, and also effectively promotes simultaneously electrical effect.

In order to realize above-mentioned purpose, the invention can be implemented by following technical scheme:

A kind of directly bonding flexible circuit jockey that is suitable on the machine plate, comprise flexible PCB and electric terminal, wherein: this flexible PCB comprises insulating barrier, electrical conductor and pad, described electrical conductor is adsorbed in described insulating barrier, described pad is communicated with described electrical conductor and is exposed to outside this insulating barrier, this electric terminal comprises weld part and the contact site that elastic portion connects, and described pad and described weld part connect as one by surface mounting technology.

In this preferred version, described electric terminal also has kink, and this kink is located between this weld part and this elastic portion.

In this preferred version, described contact site comprises the perk end that arc shaped contact and its free end oppositely extend to form.

In this preferred version, the described perk end back side is round and smooth contact-making surface.

In this preferred version, described contact site is warhead shape, comprises contact and bottom that connecting portion connects.

In this preferred version, described bottom is greater than the diameter dimension of this connecting portion.

In this preferred version, described elastic portion in a tubular form, comprises body and spring.

In this preferred version, described body comprises inner chamber, and wherein the accent end of inner chamber inwardly is provided with blocking portion, and the other end and described weld part butt are also closed.

In this preferred version, described inner chamber is to accommodate described bottom and be allowed to condition at the interior size that can do movement just, and described blocking portion is less than the size of described bottom.

In this preferred version, described spring is contained in described inner chamber, and the one end supports described bottom, and the other end supports the back side of described weld part.

Compared with prior art, its beneficial effect is in the invention:

1. not only be applicable to be connected with the direct of lithium ion battery, and be suitable for being connected with the direct of SIM card;

2. both reduced and taken the limited space of mobile phone, also convenient batch is made;

3. not only material cost can be reduced, and cost of labor can be reduced;

4. the too much fraction defective that has occurred while having avoided welding, also effectively promoted electrical effect simultaneously.

Fig. 2 faces the generalized section at visual angle in the second preferred version.

Embodiment

For persons skilled in the art can fully be understood, implement for purpose and the architectural feature that makes the invention, shown in existing combination, accompanying drawing is further described.

Please refer to Fig. 1 or shown in Figure 2, a kind of directly bonding flexible circuit jockey that is suitable on the machine plate, comprise flexible PCB 10 and electric terminal 20, wherein: this flexible PCB 10 comprises insulating barrier 11, electrical conductor 12 and pad 13, described electrical conductor 12 is adsorbed in described insulating barrier 11, described pad 13 is communicated with described electrical conductor 12 and is exposed to outside this insulating barrier 11, this electric terminal 20 comprises weld part 22 and the contact site 23 that elastic portion 21 connects, and described pad 13 is connected to one with described weld part 22 by surface mounting technology (SMT).

Refer again to shown in Figure 1, in this priority scheme: the kink 221 that also has perk between described weld part 22 and described elastic portion 21, this kink 221 is in order to raise this elastic portion 21, also the design of adopting surface mounting technology (SMT) operation and being for convenient, make by this described weld part 22 and described pad 13 not can because of the root of this elastic portion 21 from too recent photo ring welding effect between these two; Described contact site 23 has arc shaped contact 232, free end in this contact 232 extends reverse perk end 2321, the design of this perk end 2321, in the time of can avoiding external agency (not shown) excessively to exert pressure to this contact 232, the phenomenon that the free end bullet that occurs is damaged (as puncturing) this associated mechanisms to (perhaps supporting) associated mechanisms, simultaneously, the design of the round and smooth contact-making surface at these perk end 2321 back sides, when supporting this associated mechanisms, not only can not puncture this associated mechanisms, can also assist this elastic portion 21 to strengthen elastic force.

Refer again to shown in Figure 2ly, in this priority scheme: described contact site 23 is warhead shape, comprises contact 232 and bottom 233 that connecting portion 231 connects, and described bottom 233 is greater than the size of this connecting portion 231; Described elastic portion 21 in a tubular form, comprise body 211 and spring 212, described body 211 has inner chamber 2111, the one end is by described weld part 22 closures, the other end is provided with blocking portion 2112 in its accent, described inner chamber 2111 is to accommodate described bottom 233 and be allowed to condition at the interior size that can do movement just, described blocking portion 2112 is less than the size of described bottom 233, described spring 212 is contained in described inner chamber 2111, the one end supports described bottom 233, and the other end supports the back side of described weld part 22.During assembling, the inner chamber 2111 of first respectively described elastic portion 23 and spring 212 being packed into, again by described weld part 22 closures, due to the size of this blocking portion 2112 less than described elastic portion bottom 233, this elastic portion 23 that loads on call in described inner chamber 2111 can not deviate from from accent, so far make this electric terminal 20 that is assembled on described flexible PCB 10 can do flexible flexible the contact with outer connection mechanism (not shown) electrical contact the time.

To sum up lift, be to make and be familiar with this operator and can understand strictly according to the facts purpose and the effect of the invention, not to the invention any limitation in addition, implement so all persons that is familiar with the technique carry out other pattern under the spirit that does not break away from the invention, the equivalence that all should be considered as this case claim is implemented.
