Abstract
The utility model relates to a power supply terminal used in a harness relay box. The power supply terminal comprises an L-shaped wire crimping end and an L-shaped fixing end; the wire crimping end comprises a wire skin crimping portion and a wire core crimping portion; the wire skin crimping portion and the wire core crimping portion are connected at one end to form an L-shaped horizontal arm, and the other ends extends below the horizontal arm; and an anti-oxidation electroplating layer is arranged outside the power supply terminal. The power supply terminal provided by the utility model is L-shaped, installation inside the relay box is facilitated, and adjustment is easy; as the surface of the terminal is provided with the electroplating layer, oxidation can be effectively prevented; and as the wire skin crimping portion and the wire core crimping portion are located below the terminal, the upper part is tidy and attractive after wiring.
Description
Technical field
The utility model relates to automotive wire bundle field, specifically refers to a kind of for the power supply terminal on wire harness relay box.
Background technology
" relay box " Main Function using on car is anti-interference and protection circuit; it is one of most important formation component on automobile; and be arranged in relay box for be connected the power supply terminal that accesses power supply with power line; it is again the most important thing; in driving, the disappearance of power supply can cause stopping of some function on automobile; cause serious security incident, power supply terminal must possess very high intensity and electric conductivity, also must possess the characteristic of oxidation and corrosion.
Utility model content
The purpose of this utility model is to provide a kind of dependable performance and lower-cost for the power supply terminal on wire harness relay box.
The technical scheme of taking of the present utility model is: the power supply terminal using on a kind of wire harness relay box, comprise electric wire crimp end and stiff end, and described electric wire crimp end and stiff end are L-type.
Described electric wire crimp end comprises line skin pressure contact portion and core pressure contact portion.
Described line skin pressure contact portion and core pressure contact portion one end are joined together to form the horizontal arm of L, and the other end stretches to horizontal arm below.
Concrete, described stiff end is provided with circular hole.
Preferably, described power supply terminal is provided with anti-oxidant electrodeposited coating outward.
Compared with prior art, power supply terminal described in the utility model is L-type, installs, and easily regulate in convenience relay; Terminal surfaces is provided with electrodeposited coating, can effectively anti-oxidation, and line skin pressure contact portion and core pressure contact portion are positioned at terminal below, and wiring back upper place is attractive in appearance neat.
Accompanying drawing explanation
Fig. 1 is terminal structure of electric power schematic diagram described in the utility model;
Fig. 2 is another visual angle structural representation of power supply terminal described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the power supply terminal using on described wire harness relay box, comprises and is wire harness pressure connection terminal 1 and the stiff end 2 that L-type is arranged, wire harness pressure connection terminal 1 comprises line skin pressure contact portion 11 and core pressure contact portion 12, and stiff end is provided with circular hole 21.Described line skin pressure contact portion 11 and core pressure contact portion 12 one end are joined together to form the horizontal arm of L, and the other end stretches to horizontal arm below.In order to prevent being oxidized in terminal use procedure, at power supply terminal, be also provided with anti-oxidant electrodeposited coating outward.
This power supply terminal is arranged in relay box, stiff end is screwed on relay box, be electrically connected to fuse, pressure connection terminal crimped electric wire, play to the effect of other functional module power supply of car body, the bending part that its stiff end is connected with pressure connection terminal not only will be considered the workability that adds man-hour, more needs to consider the vibration producing in the process that whether can travel at vehicle and under various adverse circumstances, guarantees that relay box keeps the reliability of height.The convenient processing of L-type design is easy to adjust simultaneously, can be applicable to different concrete applied environments and suitably adjust bending angle, so that connect more firm.
Flexural strength to power supply terminal described in the utility model is tested, and the front end of terminal is fixed, and at crimping position, applies from bottom to top power more than 30kgf, and terminal has or not the place of distortion and cracking.Pull-out capacity to terminal is tested, and is clipped in the core crimping position of terminal with the upper grip of pull-out capacity test machine, and lower chuck is clamped electric wire, with the speed of 100mm/min, pulls electric wire, until electric wire pulls, reads maximum reading.During test, adopt two kinds of wire diameter results as follows: 2.0mm
2electric wire pull-out capacity is more than 250N, 8.0mm
2electric wire pull-out capacity is more than 450N.
It is more than preferably implementation of the utility model; it should be noted that; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection range of the appended claim of the utility model.
