Embodiment
Owing to the utility model discloses a kind of connector female terminal and water-proof connector, the connector female terminal that is wherein utilized is connected and the conducting principle with male terminal, and those of ordinary skills understand, so with hereinafter explanation, no longer does complete description.Simultaneously,, be intended to express the implication of the structure relevant, also do not need, formerly statement according to the complete drafting of actual size with the utility model feature with the accompanying drawing that is hereinafter contrasted.
At first, please refer to Fig. 1, Fig. 1 is first preferred embodiment that proposes according to the utility model, is a kind of connector female terminal 1.Connector female terminal 1 through one-body molded the making of mould compacting, has contact jaw 11 and binding end 12 away from contact jaw 11 with a sheet metal.Binding end 12 is to be used for combining with the core (figure does not look out) of lead, and the effect of contact jaw 11 is to make the connector male terminal 2 of elongate can insert to form the contact conducting, has the less neck of diameter 13 between contact jaw 11 and the binding end 12.Wherein, the material of connector female terminal 1 is preferably selected copper or copper alloy for use.The also optional alloy of the material of connector female terminal 1 in order to tin, lead, nickel, gold, silver, bismuth or above-mentioned metal.Visual actual demand is used.
Please continue with reference to figure 1, the contact jaw 11 of connector female terminal 1 includes hollow circular-tube 14, and an end of hollow circular-tube 14 is directly connected in neck 13, the other end forms opening 15, and opening 15 is the inlet that connector male terminal 2 inserts.And the position, stage casing of hollow circular-tube 14 is formed with a plurality of axially extended shell fragments 16 along hollow circular-tube 14, the two ends of shell fragment 16 are connected in hollow circular-tube 14, be formed with fluting 17 between each shell fragment 16, the central part of each shell fragment 16 is towards the axle center of hollow circular-tube 14 deviation.Please refer to Fig. 2, Fig. 2 is connector female terminal 1 and connector male terminal 2 the two cutaway view that engage one another.In sum, the central part of each shell fragment 16 is towards the axle center of hollow circular-tube 14 deviation, therefore will form a plurality of deviation portion 161, this a plurality of deviation portion 161 then can cause connector female terminal 1 to have elasticity, and the resilient clamp effects to the connector male terminal 2 of insertion mainly play in each deviation portion 161.Wherein the back after tested preferred amount of shell fragment 16 quantity is 3～6.If have only two shell fragments 16, then can can't effectively clamp connector male terminal 2 because of shell fragment 16 quantity very little, and then may cause connector male terminal 2 to produce the phenomenon that gets loose.But,, will make the chucking power of shell fragment 16 reduce if shell fragment 16 more than 6, then may cause shell fragment 16 width W meticulous.
Please refer to Fig. 3, the preferable range of the length L of each shell fragment 16 in the connector female terminal 1 is between between the 4.5mm to 12.5mm, the preferable range of the width W of each shell fragment 16 be between between the 0.5mm to 1.1mm and each shell fragment 16 towards the preferable range of the displacement H of the axle center of hollow circular-tube 14 deviation between between the 0.2mm to 0.8mm.What specify is, connector female terminal 1 of the present invention can have chucking power preferably, the number range that depends on length L, width W and the displacement H of above-mentioned each shell fragment 16, if each shell fragment 16 surpasses the number range of above-mentioned length L, width W and displacement H, then can't provide chucking power connector female terminal 1 preferably.
Please refer to Fig. 4, the plane graph of Fig. 4 for watching from contact jaw 11 in the connector female terminal 1, the inside diameter D of the hollow circular-tube 14 in the connector female terminal 1 in this embodiment is between the space that between the 3.0mm to 6.0mm, further can provide preferable suitable connector male terminal 2 to insert connector female terminal 1.
What specify is, the length L of each shell fragment 16 is too short, can cause each shell fragment 16 too hard and then can follow the string, and therefore, can cause the chucking power of connector female terminal 1 not good.And, if the length L of each shell fragment 16 is oversize, then can cause between connector male terminal 2 and the connector female terminal 1 to contact meeting not good because the arm of force of each shell fragment 16 is oversize, in hollow circular-tube 14, produces easily and rock.Also can cause, connector male terminal 2 is elongated with the conducting path after connector female terminal 1 contacts, and current lead-through can be not good.Can illustrate that in like manner the width W of each shell fragment 16 is too wide or too thin or the displacement H of each shell fragment 16 is too dark or too shallow, all can influence the elasticity and the chucking power of each shell fragment 16.
Under better enforcement state, the quantity of each shell fragment 16 is that 6, the length L of each shell fragment 16 are that the width W of 8.5mm, each shell fragment 16 be 0.8mm, each shell fragment 16 towards the displacement H of the axle center of hollow circular-tube 14 deviation is that the inside diameter D of 0.5mm and hollow circular-tube 14 is 4.5mm.The chucking power of the female terminal connector of making in this scope 1 can be better.Therefore, these 6 shell fragments 16 will improve the chucking power that male terminal 2 inserts back female terminal 1, make male terminal 2 and female terminal 1 be able to firm engagement.Therefore, can so that the contact strength of male terminal 2 and female terminal 1 higher, be electrically connected better.Certainly, the demand of visual actual fabrication is designed to the scope of the inside diameter D of other quantity that meets each shell fragment 16 of this preferred embodiment, length L, width W, displacement H and hollow circular-tube 14.
In addition, each shell fragment 16 in the connector female terminal 1 preferably has uniform width W, or the width W of each shell fragment 16 is narrow at central part, and visual actual demand is used.Importantly, in this preferred embodiment, the two ends of each shell fragment 16 and hollow circular-tube 14 are connected to each other, and therefore, male terminal 2 shortens with current conduction path after female terminal 1 contacts, and current lead-through is better.
Please refer to Fig. 5, according to aforementioned purpose, the utility model reintroduces second preferred embodiment, and Fig. 5 is a kind of schematic perspective view with water-proof connector 3 of connector female terminal 1.A kind of water-proof connector 3 includes insulation shell 31 and the connector female terminal 1 that is arranged in the insulation shell 31.The principal character of connector female terminal 1 and effect then with first preferred embodiment as described above in connector female terminal 1 essence identical, do not add at this and to give unnecessary details.
The above is preferred embodiment of the present utility model only, is not in order to limit the right of applying for a patent of the present utility model; Simultaneously above description should be understanded and be implemented for those of ordinary skills, so other does not break away from the equivalence of being finished under the spirit that the utility model discloses and change or modification, all should be included in the claim.
