改良式速度表線及其防水膠套Improved speedometer wire and waterproof rubber sleeve

本發明有關於速度表線,尤指一種具有高防水性及低生產成本的改良式速度表線。The invention relates to a speedometer wire, in particular to an improved speedometer wire with high water repellency and low production cost.

請參閱圖1所示,一般機車速度之偵測,乃由一速度表線連接至機車車輪A,並與機車車輪A連動以傳遞出轉速訊號。Referring to FIG. 1 , the detection of the general locomotive speed is connected to the locomotive wheel A by a speedometer wire, and is linked with the locomotive wheel A to transmit the rotational speed signal.

如圖2及圖3所示,傳統的速度表線Z’,具有一速度表線本體1、一螺帽2及一防水膠套3’。其中螺帽2套設於速度表線本體1,防水膠套3’的第一套部31’黏接於速度表線本體1上的金屬接頭13,防水膠套3’的第二套部32’圍繞速度表線本體1的塑膠軟管12,防水膠套3’的內表面抵靠塑膠軟管12且具有多道凹槽33’。As shown in Figures 2 and 3, the conventional speedometer line Z' has a speedometer wire body 1, a nut 2 and a waterproof rubber sleeve 3'. The nut 2 is sleeved on the speedometer wire body 1, the first sleeve portion 31' of the waterproof rubber sleeve 3' is adhered to the metal joint 13 on the speedometer wire body 1, and the second sleeve portion 32 of the waterproof rubber sleeve 3' 'The inner surface of the waterproof rubber sleeve 3' abuts the plastic hose 12 around the speedometer wire body 1 and has a plurality of grooves 33'.

此結構的速度表線Z’在業界已行之有年,然而經統計報告顯示,在雨季及高濕度的地區,速度表線Z’特別容易斷裂導致速度表不運轉,尤其屢屢發生在金屬接頭13與塑膠軟管12的交界處。The speedometer line Z' of this structure has been in the industry for a long time. However, according to statistical reports, in the rainy season and high humidity areas, the speedometer line Z' is particularly prone to breakage and the speedometer does not work, especially in metal joints. 13 at the junction with the plastic hose 12.

傳統的速度表線Z’採黏塗方式將防水膠套3’黏固於速度表線本體1的金屬接頭13上,並以此方式防止來自於金屬接頭13處的入水,在塗膠過程中,無可避免產生溢膠的情況,使防水膠沾黏至塑膠軟管12上,加上機車車輪A(如圖1所示)於行駛時與地面間反覆的作動時,連帶使速度表線Z’反覆作動,若防水膠產生溢膠情形時,在反覆作動的過程中,溢膠處的塑膠軟管12因此會被扯破,而露出塑膠軟管12內的金屬軟管(圖未示);並且傳統防水膠套3’的隔水效果不佳,使水氣在防水膠套3’反覆運動的變形中經由不斷的擠壓與拉伸的動作而不斷被推送至內部,加速鏽蝕露出的金屬軟管。金屬軟管的功能在於分隔轉動的金屬線11及塑膠軟管12,並且保持碼表線本體具有一定曲率,以免影響金屬線11傳遞速度訊號的功能;並且鏽蝕的金屬軟管無可避免的會有斷裂的情形,而斷裂處的金屬部分,容易與金屬線11因為車輪與地面反覆的動作而互相摩擦,長時間的摩擦後,金屬線11即受損,並造成機車車輪A的轉動訊號傳達不確實或是無法被傳遞至碼表顯示當時的速度。The traditional speedometer line Z' adopts the adhesive coating method to adhere the waterproof rubber sleeve 3' to the metal joint 13 of the speedometer wire body 1, and in this way prevents the water from the metal joint 13 from being in the glue coating process. Inevitably, the overflow glue is generated, and the waterproof glue is adhered to the plastic hose 12, and when the locomotive wheel A (shown in FIG. 1) is repeatedly operated between the driving and the ground, the speedometer line is connected. Z' is repeatedly actuated. If the waterproof glue is in the overflow condition, the plastic hose 12 at the overflow glue will be torn during the repeated operation, and the metal hose in the plastic hose 12 is exposed (not shown). And the water-repellent effect of the traditional waterproof rubber sleeve 3' is not good, so that the moisture is continuously pushed to the inside through the continuous pressing and stretching action in the deformation of the waterproof rubber sleeve 3', and the rust is exposed. Metal hose. The function of the metal hose is to separate the rotating metal wire 11 and the plastic hose 12, and maintain the coded wire body with a certain curvature so as not to affect the function of the metal wire 11 to transmit the speed signal; and the rusted metal hose is inevitable There is a case of breakage, and the metal part of the break is easy to rub with the metal wire 11 due to the action of the wheel and the ground. After a long time of friction, the wire 11 is damaged, and the rotation signal of the locomotive wheel A is transmitted. Not sure or can not be passed to the code table to show the speed at that time.

除上述因車輪反覆運動,導致碼表線溢膠處的塑膠軟管12破損、以及防水膠套3’隔水效果不佳造成破損處的鏽蝕與斷裂之原因外,在鎖附速度表線Z’時,亦常發生車輛組裝時不當施力,將鎖附螺帽2所必須的扭力作用在防水膠套3’上,造成黏著於速度表線本體1的防水膠套3’因而脫膠鬆動,鬆動後的防水膠套3’便無法發揮隔水功能。In addition to the above-mentioned repeated movement of the wheel, the plastic hose 12 at the gap of the gauge line is broken, and the waterproof rubber sleeve 3' is not well insulated, causing the rust and breakage of the damaged portion. 'When the vehicle is assembled improperly, the torque required to lock the nut 2 is applied to the waterproof rubber sleeve 3', causing the waterproof rubber sleeve 3' adhered to the speedometer wire body 1 to be loosened. The loose waterproof rubber sleeve 3' will not function as a water barrier.

此外,傳統速度表線Z’的防水膠套3’,其第一套部31’與第二套部32’相連處形成一段差,段差處為應力集中重點部份,在現行的防水膠套作動中,膠套未有足夠厚度對該部分進行應力承受,而導致在此兩材料的接合部結構支撐力較為薄弱,金屬接頭13與塑膠軟管12的交界處,雖然未有進水情形發生,也容易因為線材的反覆作動造成損壞。In addition, the waterproof rubber sleeve 3' of the conventional speedometer line Z' has a difference between the first sleeve portion 31' and the second sleeve portion 32', and the step is a stress concentration key portion in the current waterproof rubber sleeve. During the operation, the rubber sleeve is not sufficiently thick to withstand the stress of the portion, and the supporting force of the joint portion of the two materials is weak, and the junction of the metal joint 13 and the plastic hose 12 occurs, although no water inlet occurs. It is also easy to cause damage due to the repeated action of the wire.

綜上所述,傳統速度表線Z’具有以下缺點:使用防水膠增加生產成本、防水膠溢膠造成後續塑膠軟管12脫膠、防水膠套3’防水性不佳、防水膠套3’在金屬接頭13與塑膠軟管12交界處的支撐能力不佳等情形。In summary, the traditional speedometer line Z' has the following disadvantages: the use of waterproof glue increases the production cost, the waterproof glue overflows the glue to cause the subsequent plastic hose 12 to be degummed, the waterproof rubber sleeve 3' is not waterproof, and the waterproof rubber sleeve 3' The support ability of the metal joint 13 and the plastic hose 12 at the junction is not good.

本發明在於提供一種改良式速度表線,其一端用以連接機車車輪之一部位,在於節省速度表線的生產成本及提升良率,並延長使用壽命。The invention provides an improved speedometer wire, one end of which is used for connecting one part of the locomotive wheel, which saves the production cost of the speedometer line and improves the yield, and prolongs the service life.

基於上述的內容,本發明提供一種改良式速度表線,其包括一速度表線本體、一螺帽及一防水膠套。其中速度表線本體包括一金屬線及一包覆該金屬線的塑膠軟管,螺帽套設於速度表線本體上且鄰於該速度表線本體之端部以鎖附至該機車車輪之一部位,防水膠套套設於速度表線本體上,且包括一容置該螺帽的第一套部及一圍繞該速度表線本體一端的第二套部,防水膠套的內表面具有多個凸環以抵靠速度表線本體之表面,其中該第二套部包括一連接部及一包覆部。Based on the above, the present invention provides an improved speedometer wire comprising a speedometer wire body, a nut and a waterproof rubber sleeve. The speedometer wire body comprises a metal wire and a plastic hose covering the metal wire, and the nut is sleeved on the speedometer wire body and adjacent to the end of the speedometer wire body to be locked to the wheel of the locomotive. In one part, the waterproof rubber sleeve is sleeved on the speedometer wire body, and includes a first sleeve portion for accommodating the nut and a second sleeve portion surrounding one end of the speedometer wire body, and the inner surface of the waterproof rubber sleeve has a plurality of The convex ring abuts against the surface of the speedometer wire body, wherein the second sleeve portion includes a connecting portion and a covering portion.
