Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figures 1 to 6, the utility model is protected a kind of Based Intelligent Control crystal head and cable, also protects the electrical harnesses cable being formed by this Based Intelligent Control crystal head and cable attaching.Electrical harnesses cable is herein the various lines that need to utilize crystal head to be connected to transmit data with interface, such as netting twine, telephone wire etc.
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 power connection end 11, for being connected with interface.Rear end is provided with the slot of hollow, is used for pegging graft with cable.
Slot as shown in Figure 1, has bottom and two parallel side walls that are connected to two ends, bottom.Sidewall rear end is two shell fragments 13, has the ability of certain deformation laterally.And, offer first notch 14 with certain depth downwards from upper surface at each sidewall.On sidewall, also offer the second notch 15, it is positioned at the front of the first notch 14.And the second notch 15 is offered and upwards extends from bottom surface.
The front end of plastic casing 1 is that entirety has cuboid upper and lower and side, both sides, and power connection end 11 is positioned on front end end face, 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 extends back.Elastic pressuring plate 16 is used for being extruded and enters in interface so that crystal head is combined closely with interface.
Near the both sides of the edge of the upper surface of front end, offer respectively bar-shaped trough 12, this bar-shaped trough 12 is included in straight-line groove part on front end upper surface and extends to the U-lag part on two sidewalls of rear end slot, 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, 101 one-tenth flat of vertical element, 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 part are suitable, makes can just put in U-lag part.
As shown in Figure 3, every bonding jumper 100 is just encased in respectively in two bar-shaped troughs 12 of plastic casing 10, makes U-shaped bar 102 be arranged in U-lag part the inner side corresponding to 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 when bonding jumper 100 conducts electricity, will greatly reduce the electromagnetic interference of transmission line, thereby can reduce the noise of transmission line, guarantee data transmission performance.
Crystal head need to coordinate with cable and just can make described bonding jumper 100 connect circuit and realize and control the break-make of crystal head.Therefore, the utility model is also protected a kind of cable matching 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.
And because wire 213 is arranged on outside the core that transmission line 210 forms, be separated with 0.3～0.5 millimeter of even larger distance with transmission line 210, and between the two, also keep apart by protection sandwich layer, can effectively prevent electromagnetic interference.
When cable 2 and crystal head 1 are pegged graft, two wires 213 will pass respectively the joint 20 of cable 2 and be electrically connected with two bonding jumpers 100.
Particularly, as shown in Figure 4, joint 20 sides, both sides are arranged with respectively projection 23, the shape complementarity of the first notch 14 of the shape of projection 23 and crystal head 1.Further, the front end of joint 20 is arranged with parallel interval setting between 22, two elastic arms 22 of two elastic arms, and the bottom of the two connects by a joint face, and 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 utility model after being assembled into one, as shown in Figure 6.Attaching process be particularly, by pushing two elastic arms 22, distance between the two elastic deformation is diminished, thereby can enter in the slot of crystal head 1, and to 1 li of propelling of crystal head, until elastic arm 22 arrives the second notch 15, thereby elastic force release snaps onto in the second notch 15.And now, accordingly, projection 23 is clamp-oned respectively between two shell fragments 13 of slot, and snap onto in the first notch 14.
And many transmission lines 210 in cable 2 are connected on power connection end 11, two wires 213 pass to be peelled off insulated hull after joint 20 and folds 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, thereby is electrically connected with wire 213.
Two wires 213 are connected with a controller at the other end of cable 2.The interface of connecting with crystal head 1 is also correspondingly provided with in the position of two bonding jumpers 100 path being electrically connected with bonding jumper 100, gets final product the break-make of the path of pilot 213 and bonding jumper 100 by controller, thereby controls the break-make of whole crystal head.
Adopt this bonding jumper and wire to connect the structure that coordinates controller, in the time of needs electrical harnesses cable disconnection, no longer need to pull out crystal head 1, and direct conditioning controller can make crystal head broken string.Can reduce like this crystal head grafting number of times, thereby improve the life-span of crystal head.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as crystal head, cable, electrical harnesses cable, power connection end herein, do not got rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
