Abstract
The utility model relates to a novel plastic part positioning and tightening device, belonging to the field of mechanical technology and comprising a T-shaped positioning rib (1), a circuit board (2) and a plastic part (3), wherein a circuit board U-shaped positioning groove (4) is arranged on the circuit board (2); a plastic part U-shaped positioning groove (5) is arranged on the plastic part (3); the T-shaped positioning rib (1) is vertically arranged in the plastic part U-shaped positioning groove (5); and the T-shaped positioning rib (1) is in clearance fit with the circuit board U-shaped positioning groove (4) and the plastic part U-shaped positioning groove (5). The novel plastic part positioning and tightening device has the advantages of integrating the original plastic part positioning and tightening structure, having simple and reliable structure, reducing the complexity for designing and manufacturing the plastic part mould, and at the same time saving the space of the circuit board occupied by the plastic part and increasing greater design space for the circuit board.
Description
Technical field:
The utility model relates to field of mechanical technique, is specifically related to a kind of novel working of plastics location holding device.
Background technology:
In the prior art, when plastic part and wiring board assembling, location structure is what to be separated with holding out against structure, and this had both increased the working of plastics Mould design and has made complexity, has also taken the space of wiring board design.
The utility model content:
The purpose of the utility model provides a kind of novel working of plastics location holding device; It is integrated original working of plastics location, hold out against structure; Simple in structure, reliable; Reduced the working of plastics Mould design and made complexity, also saved the space of working of plastics busy line plate simultaneously, for wiring board has increased bigger design space.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises T type positioning bar 1, wiring board 2 and working of plastics 3; Described wiring board 2 is provided with wiring board U type location notch 4; Described working of plastics 3 tops are provided with working of plastics U type location notch 5, and T type positioning bar 1 is vertically set in the working of plastics U type location notch 5, and T type positioning bar 1 and wiring board U type location notch 4 and working of plastics U type location notch 5 matched in clearance.
The top of described working of plastics U type location notch 5 is designed for step and this step and wiring board 2 is interference fit, works the effect of holding out against.
The two bottom sides of described working of plastics 3 is symmetrically arranged with groove 6, increases the elasticity that working of plastics U type location notch 5 holds out against wiring board.
The utlity model has following beneficial effect: it is integrated original working of plastics location, hold out against structure; Simple in structure, reliable; Reduced the working of plastics Mould design and made complexity, also saved the space of working of plastics busy line plate simultaneously, for wiring board has increased bigger design space.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the structural representation of working of plastics in the utility model.
Embodiment:
Referring to Fig. 1-2; This embodiment adopts following technical scheme: it comprises T type positioning bar 1, wiring board 2 and working of plastics 3; Described wiring board 2 is provided with wiring board U type location notch 4; Described working of plastics 3 tops are provided with working of plastics U type location notch 5, and T type positioning bar 1 is vertically set in the working of plastics U type location notch 5, and T type positioning bar 1 and wiring board U type location notch 4 and working of plastics U type location notch 5 matched in clearance.
The top of described working of plastics U type location notch 5 is designed for step and this step and wiring board 2 is interference fit, works the effect of holding out against.
The two bottom sides of described working of plastics 3 is symmetrically arranged with groove 6, increases the elasticity that working of plastics U type location notch 5 holds out against wiring board.
This embodiment is in when assembling, T type positioning bar 1 respectively with wiring board U type location notch 4, working of plastics U type location notch 5 matched in clearance, play the role of positioning; Working of plastics U type location notch 5 tops be provided with step 4 and with the wiring board interference fit, the effect of the tight wiring board of top lifting is in addition in the two bottom sides straight flange outer rim of working of plastics U type location notch 5; Increase groove 6 respectively, with the elasticity of reinforced plastics spare U type location notch 5 structures, avoid because of the power that holds out against wiring board excessive; Cause the wiring board distortion, influence performance.
This embodiment is integrated original working of plastics location, hold out against structure; Simple in structure, reliable; Reduced the working of plastics Mould design and made complexity, also saved the space of working of plastics busy line plate simultaneously, for wiring board has increased bigger design space.
