Referring to fig. 1-3, the wire-clamping fixing structure for wire rods of an instrument and meter provided in this embodiment includes a bottom plate 1, a side plate 2 located on the bottom plate 1 and vertically connected to the bottom plate 1, and a plurality of fixing slot groups, each fixing slot group is used to fix a wire rod 8, the bottom plate 1 can be a bottom plate 1 of the instrument and meter, the side plate 2 can be a front panel of the instrument and meter, each fixing slot group includes a through hole 3 for the wire rod 8 to pass through, a first wire clamping seat 4 for clamping the wire rod 8, and a second wire clamping seat 5 for clamping the wire rod 8, the through hole 3 is disposed on the side plate 2, the first wire clamping seat 4 and the second wire clamping seat 5 are fixedly connected to the bottom plate 1, the first wire clamping seat 4 is disposed opposite to the through hole 3, the second wire clamping seat 5 is disposed in a staggered manner with respect to the through hole 3, that is the wire rod 8 between the through hole 3 and the first wire clamping seat 4 is linearly disposed, the wire rod 8 between the second wire clamping seat 5 and the first wire clamping seat 4 is bent, the second wire clamping seat 5 is not on the straight line of the connecting line between the first wire clamping seat 4 and the through hole 3.

With such an arrangement, during the production and assembly process, one end of each wire 8 is fixed to the internal circuit board by welding or connector connection, then is flatly pressed and fixed to the second wire clamping seat 5 along the length direction, then is flatly pressed into the first wire clamping seat 4 along the offset direction, and finally passes through the through-hole 3 along the length direction to complete the penetration from the instrument, and the part of each wire 8 in the instrument is subjected to auxiliary fixation through each fixing groove group, specifically, for the following stress analysis, the wire 8 is divided into a first section located outside the instrument, a second section located between the side plate 2 and the first wire clamping seat 4, a third section located between the first wire clamping seat 4 and the second wire clamping seat 5 and close to the first wire clamping seat 4, a fourth section located between the first wire clamping seat 4 and the second wire clamping seat 5 and close to the second wire clamping seat 5, and a fourth section located between the first wire clamping seat 4 and the second wire clamping seat 5 and close to the second wire clamping seat 5, through the wire clamping fixing structure of the instrument, The fifth section is positioned between the second wire clamping seat 5 and the internal circuit board, when the first section of the wire 8 positioned outside the instrument receives external force in any direction, the external force is decomposed into force in the direction vertical to the Y axis of the side plate 2 and force in the direction parallel to the X axis of the side plate 2 through force decomposition, and the force in the direction of the X axis and the friction force between the wire 8 and the side plate 2 are balanced, so that when the wire 8 receives tensile force vertical to the side plate 2, the tensile force received by the second section of the wire 8 is the largest; at this time, the third section and the fourth section of the wire 8 are changed from bending to straight lines due to the action of the pulling force, and the pulling force is decomposed into an acting force parallel to the third section of the wire 8 and an acting force parallel to the supporting force of the first wire clamping seat 4, and by the same way, the force analysis between the fourth section of the wire 8 and the second wire clamping seat 5 can be obtained, to sum up, when the wire 8 is pulled outwards by the external force, the fixation of the wire 8 is mainly controlled by the friction force of the first wire clamping seat 4, the main parameters of the friction force are pressure and friction coefficient, that is, the pulling force and the supporting force of the first wire clamping seat 4 and the friction coefficient of the wire 8 and the side plate 2 of the instrument housing, because the wire 8 on the market is made of plastic, the instrument housing is mostly made of bakelite, plastic and metal, the static friction coefficient of the wire 8 and the instrument housing is large, the pulling force applied to the first section of the wire 8 is offset with the acting force in the instrument, and the wire 8 is prevented from being pulled out. This card line fixed knot of instrument and meter wire rod constructs is with low costs of processing, can not hinder the later stage to instrument and meter's maintenance after using moreover, has solved the problem that the process that prevents wire rod 8 in the instrument and meter casing among the prior art from producing not hard up can cause later maintenance inconvenience, increase manufacturing cost.

Preferably, the through-line hole 3, the first wire clamping seat 4 and the second wire clamping seat 5 are all in pressing contact with the wire 8.

It should be noted that the four groups of fixing grooves shown in fig. 1-2 are only for convenience of illustration, and do not represent that the fixing groove groups are provided with exact numbers, and in the wire clamping and fixing structure of the instrument and meter wire rod, the number of the fixing groove groups is set as required in the design and production, and is arbitrary.

As a specific embodiment, each of the first wire clamping seat 4 and the second wire clamping seat 5 includes a seat body 6 fixedly connected to the bottom plate 1, and an open slot 7 disposed in the seat body 6, wherein the open slot 7 can squeeze and accommodate the wire 8, so that the wire 8 is clamped; the through hole 3 is a round hole. So set up, lead to line hole 3, first card line seat 4 and second card line seat 5 be convenient for process.

As a preferred embodiment, the side of the open slot 7 close to the side plate 2 is narrower than the side far from the side plate 2 to prevent the wire 8 from being pushed by external force to move relative to the base 6, i.e. the side close to the side plate 2 is smaller than the side far from the side plate 2. So set up, when wire 8 pushed to the instrument and meter inside by the instrument and meter outside, first card line seat 4 and second card line seat 5 can form a reaction force in the one side department that is close to curb plate 2 of open slot 7, and this reaction force has restrained wire 8 by the inboard thrust in the outside to play and restrained wire 8 and pushed the effect to inside by the outside.

In a more specific embodiment, the open groove 7 is provided to include a notch section 71, a groove bottom section 72 in communication with the notch section 71, the notch section 71 being narrower than the groove bottom section 72. Further, it is preferable that the cross section of the slot bottom section 72 has a fan shape with a central angle larger than 180 °, and the cross section of the slot mouth section 71 has a rectangular shape.
