Embodiment
With reference to Figure 1A, electric coupler component 200 comprises electric connector 202 and flat flexible cable, and this flat flexible cable also is called as the flexible print circuit (FPC) 22 that is used to be installed on the electric connector 202.Electric connector 202 comprises the connector shell 204 of dielectric or electric insulation.Shown in Fig. 2 A-C, connector shell 204 comprises the shell body 205 that is essentially rectangle equally, and it defines top 206, opposite bottom 208, front end 210, back end opposite 212, and opposite sidepiece 214.In the first and second opposite case surface first, for example 206 places on the top are configured to match with complementary connector, and the second opposite case surface, and for example 208 places in the bottom are configured to fastening flat flexible cable 22.Therefore, connector shell 204 defines the mating interface 216 that is disposed near top 206, and is disposed at the mounting interface 218 near bottom 208.Mounting interface 218 is used for operability ground and engages flat flexible cable, and mating interface 216 is used for the operability ground joint second complementary electrical connector simultaneously.The front end 210 of connector shell 204 can be formed with rib shown in Fig. 2 A-B, shown in Fig. 3 A-E, be smooth basically perhaps.
It is understandable that connector shell 204 can make up according to needed any suitable embodiment example.For example, shown in Fig. 2 B, the bottom 208 of connector shell 204 can come down to put down, and places in the plane that is limited longitudinal direction L and lateral A.Replacedly, shown in Fig. 2 C, the rib 203 that the bottom 208 of connector shell 204 can limit L each interval in a longitudinal direction and come by adjacent grooves 205 each intervals.This rib that replaces 203 and groove 205 can be along lateral from connector shell 204 front end 210 extend to the rear end 212 of connector shell 204.Further, shown in Fig. 2 A-B, rib 203 and groove 205 can be along whole or at least a portion extensions of the front end 210 of connector shell 204.The structure of the groove 205 at front end 210 places of connector shell 204 and size are used to hold the part of the electric terminal 200 that is installed on the connector shell 204.Alternative, shown in Fig. 3 A-E, the front end 210 of connector shell can come down to level and smooth.
Referring now to Fig. 1 and Fig. 3 A-4C, electric connector 202 comprises the electric terminal 220 of a plurality of conductions, and electric terminal 220 is kept by connector shell 204 or supports.As required, electric connector 202 can comprise any amount of electric terminal 220.Each electric terminal 220 is defined for and is electrically connected to; For example be electrically connected to removedly; The mating part 222 of the complementary electric terminal of the complementary electric component that cooperates with electric connector 202, and the opposite mounting portion 224 that is used to be electrically connected to flat flexible cable 22.Mating part 222 is configured near mating interface 216 places, and opposite mounting portion 224 is configured near mounting interface 218 places.Particularly; When electric terminal 220 is installed in 204 last times of connector shell fully; Mating part 222 extends on lateral A in fact along top 206; And can be from the top 206 stretch out, and extend on lateral A in fact along bottom 208 mounting portion 224 of electric terminal 220.
Each electric terminal 220 can be configured to battery terminal, and can comprise the terminal bodies that limits mating part 222 and mounting portion 224, and is connected the mid portion 250 between mating part 222 and the mounting portion 224.According to shown in embodiment, mating part 222 is an one with mounting portion 224 and mid portion 250 each other.Further; According to illustrated embodiment; When electric terminal 220 is installed on the connector shell fully; Mating part 222 all extends along identical direction from corresponding first and second interval locations of middle part 250 with mounting portion 224, for example backward, thereby makes mating part 222 and mounting portion 224 on horizontal direction T, align.Therefore, the line that on horizontal direction T, extends can pass mating part 222 and mounting portion 224.The top 250a of mating part 222 part from the centre extends also and is cantilever-shaped, and mounting portion 224 is extended and is cantilever-shaped from the opposite bottom 250b of middle part 250.Mating part 222 defines contact portion 256; Contact portion 256 wherein presents hook-type in fact and limits contact surface; Contact surface is used for realizing that with complementary electric terminal machinery contacts with electric; Thereby make mating part 222 place the compression shape, so mating part 222 is engaged to complementary electric terminal reliably.
At least one may further include at least one welded part 267 until the mounting portion 224 of all electric terminals 220; For example a pair of welded part 267a and 267b; Its length direction along electric terminal separates each other, for example along lateral A, and by mounting panel 262 supports.Particularly, each welded part 267 comprises a plurality of crimping teeth 268, and according to illustrated embodiment, crimping tooth 268 224 stretches out for example down to gradually thin far-end 268a from the mounting portion.For example, each crimping tooth 269 can limit the pedestal 268b that is mounted to mounting panel 262 and the far-end 268a that separates of direction T and pedestal 268b transversely.So each welded part 267 can be along a direction from mounting panel 262 extends, this direction is parallel to the direction that opened in 224 minutes mating part 222 and mounting portion in fact.
As shown, crimping tooth 268 can cut out from mounting panel 262 through punching press or alternate manner, thereby defines the perforation 270 that is horizontally through this mounting panel 262 at each welded part place.Alternative, crimping tooth 268 can be installed (for example welding) to mounting panel 262 discretely.Welded part 267 can comprise the peripheral equally spaced each interval of 268, four crimping teeth 268 of four crimping teeth around perforation 270, and mounting panel 262 is passed in perforation 270 transversely direction T.The crimping tooth 268 of each welded part 267 can be set to around circumference; For example center on the circumference of perforation 270; Perhaps other curved surface makes each welded part 267 similar starriness with any amount salient angle, according to shown in each salient angle of embodiment limit in a crimping tooth 268.It is understandable that, yet each welded part 267 can comprise at least one crimping tooth the equidistant each other or variable range of for example a plurality of crimping teeth 268 spaced apart.The crimping tooth 268 of each welded part 267 can circumferential each other interval, perhaps arranges with any suitable mode that substitutes.
In operating process, at least one electric terminal 220 can be configured to provide elastic force until all electric terminals 220, and this elastic force has the directional component of the contact surface that is orthogonal to mating part 222 in fact.For example, the contact surface of mating part 222 can contact with electric with the electric terminal machine tool of complementation, thereby mating part 222 places pressured state, thereby mating part 222 is engaged to complementary electric terminal reliably.For example, when the contact surface of mating part 222 is received in horizontal direction T towards the mounting portion during 224 power (for example being provided by complementary electric terminal), at least a portion of electric terminal 220 is crooked so that along horizontal direction T 224 pressurizations towards the mounting portion.
With reference to Fig. 3 A-C, thereby mounting portion 224 mounting panels 262 can stretch out from connector shell 204 during punching operation, thereby make being supported such as first mould by strutting piece with crimping tooth 268 opposite surfaces of electric terminal 220.For example, mounting panel 262 can stretch out on the top 206 along a direction from connector shell 204, and the substantially parallel or coplane of this direction is in the top 206 of connector shell 204 (therefore in first plane that is limited horizontal direction A and longitudinal direction L, extending).Alternative, mounting panel 262 can be along extend (therefore in being different from second plane on first plane, extending) with respect to the direction of top 206 angled skews, shown in Fig. 3 D-E.Flat flexible cable 22 can place contiguous crimping tooth 268, for example contiguous gradually thin far-end 268a, and lean on mutually with crimping tooth 268, thus make crimping tooth 268 pierce through flat flexible cable 22 and extend through from flat flexible cable 22.Second mould can place crimping tooth 268 near, thereby make flat flexible cable 22 and mounting portion 224 be configured between first and second moulds.First and second moulds move towards each other after crimping tooth 268 thorns pass flat flexible cable 22, thereby cause crimping tooth 268 to turn back towards flat flexible cable 22, thereby make gradually thin far-end 268a be embedded in the flat flexible cable 22.Replacedly; Crimping tooth 268 can pierce through flat flexible cable 22; And mounting panel 262 can be by putting to connector shell; And in order to reduce the crimp force that in the punching operation process, is applied to connector shell 204, connector shell 204 can adopt plate or other any suitable structure to strengthen, for example a reinforcement instrument; It can be as required at the inner surface of welded part 267 places support and connection device shell 204, thereby the integral body of support structure to connector shell 204 is provided when crimp force is applied to crimping tooth 268 with connector shell 204.When not crimping; Crimping tooth 268 can have any height as required; It is understandable that when the height of crimping tooth 268 increased, crimping tooth 268 can press down in the situation that the stamping press that is applied to connector shell 204 reduces and abut against on the flat flexible cable 22.
When being crimped to flat flexible cable 22, crimping tooth 268 can make electric terminal 220 will be matched with the complementary electrical device of air and flat flexible cable 22 electric connections of the mating part 222 of electric terminal 220.So flat flexible cable 22 can limit first end of the mounting portion 224 that is installed in terminal, and opposite second end that is electrically connected to the complementary electrical device of air, the complementary electrical device of air for example is transducer or processor.So flat flexible cable 22 can be provided with mounting portion 224 electric connections of processor and electric terminal 220, and mating part 222 can be connected with transducer is electric.Opposite, flat flexible cable 22 can be provided with mounting portion 224 electric connections of transducer and electric terminal 220, and mating part 222 can be electrically connected with processor.It is understandable that welded part 267 can ensure and the flexibly connecting of complementary electrical device of air, and allows electric terminal 202 when making easily, having compact design simultaneously.
With reference to Fig. 4 A-C; Electric terminal 220 also is included at least one welded part 267 at 224 places, mounting portion; For example first or inner welded part 267a and second or outside welded part 267b; Outside welded part 267b outside (for example work as electric terminal 220 and be installed in fully on the connector shell 204, outside welded part 267b backward) separates with inner welded part 267a.The crimping tooth 268 of the first welded part 267a can be configured to around first periphery, and first periphery can be the periphery of first perforation 270, and the crimping tooth of second welded part 268 can be configured to around second periphery that is different from first periphery.For example, second periphery can be discontinuous with first periphery.According to shown in embodiment, second periphery can be perforation 270 a periphery, it is different from the perforation 270 of the first welded part 267a.Further, first and second peripheries can come down to circular or alternative shape.Electric terminal 220 can dispose with the form of one or more pairs of 269 electric terminals 220.Each is to the second electric terminal 220b of first electric terminal 220a that can comprise electric terminal 220 and the electric terminal 220 that is close to the first electric terminal 220a.So electric connector 202 can limit at least one first electric terminal 220a and at least one second electric terminal 220b.
The first and second electric terminal 220a and 220b can alternately be provided with along connector shell 204 on longitudinal direction L.Therefore; The first electric terminal 220a is configured to be close to the second electric terminal 220b and can between the second electric terminal 220b, dispose, and the second electric terminal 220b is configured to be close to the first electric terminal 220a and can between the first electric terminal 220a, dispose.The first welded part 267a of each first electric terminal 220a L alignment in a longitudinal direction, and the second welded part 267b of each first electric terminal 220a L alignment in a longitudinal direction.So the straight line that on longitudinal direction L, extends can pass the center of the first welded part 267a of the first electric terminal 220a in fact, and the straight line that on longitudinal direction L, extends can pass the center of the second welded part 267b of the first electric terminal 220a in fact.Same, the first welded part 267a of each second electric terminal 220b L alignment in a longitudinal direction, the second welded part 267b of each second electric terminal 220b L alignment in a longitudinal direction.So; Straight line on longitudinal direction L can pass the center of the first welded part 267a of the second electric terminal 220b in fact, and the straight line on longitudinal direction L can pass the center of the second welded part 267b of the second electric terminal 220b in fact.
According to shown in embodiment, the first welded part 267a of each first electric terminal 220a squints along lateral A with respect to the first and second welded part 267a and the 267b of each second electric terminal 220b.So; The first welded part 267a of each first electric terminal 220a L does not in a longitudinal direction align with the first welded part 267a of each second terminal 267b, and the first welded part 267a of each first electric terminal 220a in a longitudinal direction L do not align with the second welded part 267b of each second electric terminal 220b.Therefore, L extends and the straight line at center that passes the first welded part 267a of the first electric terminal 220a does not pass one or both centers of the first or second welded part 267a or the 267b of the second electric terminal 220b in a longitudinal direction.Likewise, the second welded part 267b of each first electric terminal 220a is along first and second welded part 267as and the 267b skew of lateral A with respect to each second electric terminal 220b.Therefore, L extends and the straight line at center that passes the second welded part 267b of the first electric terminal 220a does not pass one or both centers of the first or second welded part 267a or the 267b of the second electric terminal 220b in a longitudinal direction.
Similarly, the first welded part 267a of each second electric terminal 220b squints along lateral A with respect to the first and second welded part 267a and the 267b of each first electric terminal 220a.So, the first welded part 267a of each second electric terminal 220b not with the first welded part 267a of each first electric terminal 220a in a longitudinal direction L align.The first welded part 267a of each second electric terminal 220b further not with the second welded part 267b of each first electric terminal 220a in a longitudinal direction L align.Therefore, extend and the straight line that passes the second electric terminal 220b, the first welded part 267A center does not pass the first or second welded part 267a and one of 267b or both centers of the first electric terminal 220a along vertical L.Same, the second welded part 267b of each second electric terminal 220b squints along lateral A with respect to the first and second welded part 267a and the 267b of each first electric terminal 220a.Therefore, L extends and the straight line at center that passes the second welded part 267b of the second electric terminal 220b does not pass one or both centers of the first or second welded part 267a and the 267b of the first electric terminal 220a in a longitudinal direction.
The first and second welded part 267a of the second electric terminal 220b and 267b be with respect to the first and second welded part 267a and the outside layout of 267b side direction of the first electric terminal 220a, however it is understandable that the first electric terminal 220a the first and second welded part 267a and 267b can with respect to the first and second welded part 267a of the second electric terminal 220b and 267b side direction outside and dispose.
Each welded part 267 comprises a plurality of outward extending conduction crimping teeth 268, and crimping tooth 268 is used for fastening flat flexible cable 22 with the described mode of preceding text.For example, a conductive traces that is used to be electrically connected to flat flexible cable 22 among the first and second welded part 267a and the 267b, and in first and second welded parts another is used for to the parts that are electrically connected to flat flexible cable 22 strain relief being provided.For example; The crimping tooth 268 of the second welded part 267b can engage with flat flexible cable 22; Thereby make the major part of tension force of the backward directions be applied to FPC be passed to the crimping tooth 268 of the second welded part 267b, the crimping tooth 268 that is electrically connected to the first welded part 267a of flat flexible cable 22 does not simultaneously have owing to the tension force that applies squints out and being electrically connected of flat flexible cable 22.It is understandable that; When electric terminal 220 is electrically connected to flat flexible cable 22; Flat flexible cable 22 extends to the second welded part 267b along direction backward from the first welded part 267a, and limits the length bigger than distance between the rear end 212 of the second welded part 267b and connector shell 204.
According to the embodiment shown in Fig. 1-4C, the crimping tooth 268 that each the first and second welded part 267a of each first and second electric terminal 220a and 220b and 267b can have equal number.
Referring now to Fig. 5 A-6C; It is understandable that; Selected at least one; For example a plurality of, so that among the first and second welded part 267a of all first and second electric terminal 220a and 220b and the 267b one, can have the crimping tooth 268 of different numbers with respect among the first and second welded part 267a and the 267b another.For example, according to described embodiment, with respect to the quantity of the first welded part 267a crimping tooth 268 of the second electric terminal 220b, the second welded part 267b of the second electric terminal 220b can have varying number for example still less or more crimping tooth 268.Further, one of the first and second welded part 267a of the first electric terminal 220a and 267b can have the tooth of equal number with the first and second welded part 267a of the first electric terminal 220a and among the 267b another.The tooth that the first and second welded part 267a of the first electric terminal 220a and 267b can have identical or different quantity with the second welded part 267b of the second electric terminal 220b.
