Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figures 1 to 6, the present invention protects a kind of intelligent control crystal head and cable, also protects the electrical harnesses cable by this intelligent control crystal head and cable attaching.Electrical harnesses cable is herein variously need to utilize crystal head to be connected line to transmit data, such as netting twine, telephone wire etc. with interface.
The crystal head of preferred embodiment as shown in Figure 1, Figure 2, Figure 3 shows, comprises plastic casing 1 and bonding jumper 100.Wherein, plastic casing 1 front end is provided with electrical terminals 11, for being connected with interface.Rear end is provided with the slot of hollow, is used for and cable grafting.
Slot as shown in Figure 1, has bottom and two parallel side walls being connected to two ends, bottom.Sidewall rear end is two shell fragments 13, has the ability of certain deformation laterally.Further, offer first notch 14 with certain depth downwards from upper surface at each sidewall.Sidewall also offers the second notch 15, and it is positioned at the front of the first notch 14.And the second notch 15 is offered from bottom surface and is upwards extended.
The front end of plastic casing 1 is that entirety has cuboid that is upper and lower and side, both sides, and electrical terminals 11 is positioned in front end surface, and the bottom of elastic pressuring plate 16 is connected on the position of the close front end face of upper surface, and free end then extends back.Elastic pressuring plate 16 is used for being extruded and entering in interface to make crystal head be combined closely with interface.
Bar-shaped trough 12 is offered respectively near the both sides of the edge of the upper surface of front end, the U-lag part that this bar-shaped trough 12 is included in the straight-line groove part on the upper surface of front end and extends on rear end slot two sidewalls, and this U-lag part and the first notch 14 are arranged side by side.
Bar-shaped trough 12 is used for holding bonding jumper 100.As shown in Figure 2, bonding jumper 100 comprises vertical element 101 and U-shaped bar 102.Wherein, vertical element 101 one-tenth flat, suitable with straight-line groove partial shape.The free end of U-shaped bar 102 is connected with the end of vertical element 101 and perpendicular to vertical element 101, its shape and U-lag body fit, make can just put in U-lag part.
As shown in Figure 3, every root bonding jumper 100 is just encased in two bar-shaped troughs 12 of plastic casing 10 respectively, makes U-shaped bar 102 be arranged in U-lag part and corresponds to the inner side of the first notch 14.In order to strengthen adhesion, bonding jumper 100 can be adhered in bar-shaped trough 12.
Two bonding jumpers 100 are owing to being positioned on the outer surface of plastic casing 10, keep apart with the transmission line of plastic casing 10 inside, therefore greatly will reduce the electromagnetic interference of transmission line when bonding jumper 100 conducts electricity, thus the noise of transmission line can be reduced, ensure data transmission performance.
Crystal head needs to coordinate with cable just to make described bonding jumper 100 connect circuit and realize controlling the break-make of crystal head.Therefore, the present invention also protects a kind of cable matched with this crystal head.
Particularly, as shown in Figure 4, Figure 5, cable 2 comprises wire harness 21 and joint 20, and joint 20 is used for being connected with the rear end slot of crystal head 1.
Wire harness 21 as shown in Figure 5; comprise for being connected to carry out the core of transfer of data with the electrical terminals 11 of crystal head 1, core comprises many transmission lines 210, is generally 8; every root transmission line 210 is coated by insulating barrier respectively, and many transmission line 210 entirety are coated by the protection sandwich layer 211 of insulation.Usually, the cross section of the core of transmission line 210 and protection sandwich layer 211 formation is circular.
Wire harness 21 is also provided with two wires 213 being used for respectively being electrically connected with two bonding jumpers 100, and it is placed on the both sides of core outer surface symmetrically, then by outer 212 integral coating of protection, makes ellipsoidal cross section or the approximate ellipsoidal of wire harness 21.Adopt oval wire harness 21, extra manufacturing cost can not be increased, be applicable to the various equipment of the circular cable of existing making.
And due to wire 213 be arranged on outside core that transmission line 210 forms, being separated with 0.3 ~ 0.5 millimeter of even larger distance with transmission line 210, therebetween also by protecting sandwich layer to keep apart, effectively can preventing electromagnetic interference.
When cable 2 and crystal head 1 grafting, two wires 213 will be each passed through the joint 20 of cable 2 and be electrically connected with two bonding jumpers 100.
Particularly, as shown in Figure 4, side, joint 20 both sides is arranged with projection 23 respectively, the shape complementarity of the shape of projection 23 and the first notch 14 of crystal head 1.Further, the front end of joint 20 is arranged with parallel interval between two elastic arms, 22, two elastic arms 22 and arranges, and the bottom of the two is connected by a joint face, and the distance between two elastic arms 22 is slightly larger than the distance between two projections 23.
Above-mentioned crystal head 1 and cable 2 can obtain the claimed electrical harnesses cable of the present invention after being assembled into one, as shown in Figure 6.Attaching process be particularly, by extruding two elastic arms 22, the spacing of the two elastic deformation is diminished, thus can enter in the slot of crystal head 1, and to crystal head 1 li propelling, until elastic arm 22 arrives the second notch 15, elastic force discharges thus snaps onto in the second notch 15.And now, accordingly, projection 23 is clamp-oned between two shell fragments 13 of slot respectively, and snap onto in the first notch 14.
And the many transmission lines 210 in cable 2 are connected on electrical terminals 11, peel off insulated hull after two wires 213 pass joint 20 and fold in U-lag part.Bonding jumper 100 is encased in bar-shaped trough 12, and U-shaped bar 102 is encased in U-lag part, thus is electrically connected with wire 213.
Two wires 213 are connected with a controller at the other end of cable 2.The interface connected with crystal head 1 is also correspondingly provided with the path be electrically connected with bonding jumper 100 in the position of two bonding jumpers 100, then got final product the break-make of the path of pilot 213 and bonding jumper 100 by controller, thus control the break-make of whole crystal head.
Adopt this bonding jumper and wire to connect the structure coordinating controller, when needs electrical harnesses cable disconnection, no longer need to pull out crystal head 1, and direct conditioning controller, crystal head can be made to break.Crystal head grafting number of times can be reduced like this, thus improve the life-span of crystal head.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as crystal head, cable, electrical harnesses cable, electrical terminals herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
