Abstract

The utility model relates to a GPS receiver with waterproof structure. The technical proposal of the utility model is that a signal wire is connected with a round opening of the receiver main body; the surface of the signal wire is provided with a waterproof segment which is sleeved inside the round opening; and the surface of the waterproof segment is provided with a circular concave groove which is used for arranging a waterproof gasket. Thereby, when the signal wire is connected with the receiver main body, the connection position of the signal wire and the receiver main body has good waterproof efficiency by tightly resisting the waterproof gasket on the wall of the opening.

Description

GPS receiver with waterproof construction

Technical field

The utility model is a kind of GPS receiver with waterproof construction, refers to especially a kind ofly form waterproof construction in holding wire itself, has preferable waterproof effect with the joint that holding wire and receiver body are provided.

Background technology

Consult shown in Figure 3, traditional GPS receiver, with regard to its structure, its structure roughly includes a receiver body, and is located at the holding wire that the circuit board, of this receiver body interior wore this receiver body and was connected with internal circuit board, and wherein this receiver body is to be covered by upper and lower two housings to form.In the lower house 30 outstanding annulus 31 that is formed with in edge of a side wherein, for wearing central openings 311 wherein, holding wire 32 is connected with the circuit board formation not shown in the figures of lower house 30 inside, and the edge of this upper shell (not shown) is with respect to one arc notch of annulus 31 formation of lower house 30, make upper and lower casing when covering mutually, this annulus 31 can relative driving fit with arc notch.

When holding wire 32 wherein wore the hollow and annular portion 31 of lower house 30, and upper and lower casing is after covering, avoid aqueous vapor to enter the receiver body interior for asking, and influence the circuit board regular event, so the central openings 311 in hollow and annular portion 31 is to refill viscose glue, to strengthen the adaptation between holding wire 32 and central openings 311 hole walls.Its major defect is:

1, this kind driving fit mode is inhomogeneous if fill viscose glue, or viscose glue when still unhardened this holding wire 32 torn, will cause holding wire 32 and annulus 31 sealing property between the two to have a greatly reduced quality, so waterproof action promptly is affected.

2 moreover, after continue using a period of time, the number of times that is subjected to scratching along with this holding wire 32 increases gradually, suitably is filled in this perforate 311 places if engage the previous nothing of viscose glue of usefulness, similarly causes the slit to produce easily, and reduces waterproof action.

Summary of the invention

Main purpose of the present utility model provides a kind of GPS receiver with waterproof construction, be formed with a waterproof construction by holding wire surface in receiver, be beneficial to holding wire and wear into receiver when inner, the joint that reaches holding wire and receiver has the purpose of preferable waterproof effect.

The purpose of this utility model is achieved in that a kind of GPS receiver with waterproof construction, the surface that is included in the receiver body is formed with a perforate, and be provided with circuit board in this receiver body interior, it is characterized in that: holding wire is that the perforate from this body penetrates with this circuit board and is connected, the surface of this holding wire is formed with the waterproof section and is close to supporting of this waterproof section ends section, the external diameter of this waterproof section is the aperture that is slightly less than described perforate, the external diameter that should support end section is the aperture greater than described perforate, and the surface of this waterproof section is formed with first groove that is nested with a waterproof washer; This holding wire wore this perforate, and was connected with body interior circuit board formation, and described is to be positioned at this lateral surface external and this perforate of conflicting to ending section, and described waterproof section is in the perforate of position, and this waterproof washer is closely to contact at this perforate wall.

This waterproof section is to be formed with second groove that is nested with a catch, and this catch is positioned at this reception body interior and the medial surface of this perforate of conflicting.First groove of this waterproof section is an annular recess, is nested with described waterproof washer; This second groove is side's shape groove, is nested with described catch.This catch is to be a  font.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Embodiment

Consult Fig. 1-shown in Figure 2, global positioning system (Globalpositioning system with waterproof construction of the present utility model, GPS) receiver connects a holding wire 10 by a receiver body and is formed, the (not shown) of holding in addition of this holding wire 10 is to be connected with a Port, can be connected for constituting signal with gps system.Wherein this receiver body is to be covered on a lower house 21 with a upper shell 20 to be formed, in body interior is to be provided with a circuit board (not shown) again, and in this lower house 21 wherein an edge be to be formed with an annulus 22, the central authorities of this annulus 22 are a circular hollow aperture 23, can supply aforementioned holding wire 10 wear and enter, and be connected with the circuit board of body interior.

The surface of aforementioned holding wire 10, be to take injection molding method earlier, utilize the rubber material to form supporting of a waterproof section 11 and this waterproof section 11 of next-door neighbour and end section 12, the external diameter design of this waterproof section 11 is the apertures that are slightly less than this perforate 23, to make things convenient for holding wire 10 to penetrate this perforate 23, the aforementioned external diameter that ends section 12 that supports then must after penetrating perforate 23 in holding wire 10, provide a block to act on the lateral surface of perforate 23 greater than the aperture of this perforate 23.Be formed with one annular recess 13 and side's shape groove 14 in the front and back on the surface of this waterproof section 11, supply a waterproof washer 15 and a catch 16 sheathed respectively.

Consult shown in Figure 2, this holding wire 10 is to wear aforementioned waterproof washer 15 earlier, it is placed in the annular recess 13, and penetrate aforementioned perforate 23 again, so that this waterproof section 11 places in the perforate 23, aforementioned waterproof washer 15 fetters because of the wall that is subjected to perforate 23 simultaneously, and can closely contact at the wall of perforate 23, provides by this to have preferable waterproof effect.

Square shape groove 14 parts of this waterproof section 11 wherein, be to protrude in aforementioned perforate 23, and in lower house 21 inside, and make in aforementioned catch 16 side's of being placed on shape grooves 14, this catch 16 is to adopt metal to make, and its outward appearance is to be made of a horizontal part and the vertical component effect that extended by this horizontal part two ends respectively, generally speaking slightly be a  font, its central authorities form a breach, bridging in square shape groove 14, and collude with the two free-ended hook portions that are formed at vertical component effect and to be combined in this horizontal segment 11.By this catch 16 conflict medial surface of perforate 23, in the time of can avoiding this holding wire 10 to pull, avulse from the receiver body interior by the outside.

By learning in the above-mentioned detailed description, the utlity model has global positioning system (GPS) receiver of waterproof construction, it is by waterproof washer is set on the holding wire, and provides holding wire and receiver when engaging, and more traditional viscose glue mode has preferable waterproof effect.

In sum, the utility model preferred embodiment have a body explanation, but not in order to limit claim of the present utility model, moreover the utility model has really had aforementioned advantages, and having obvious effect compared to prior art promotes, therefore, the utlity model has novelty, creativeness and practicality.
