Description

具有高差分特性阻抗的电连接器 Having a high characteristic impedance differential electrical connector

技术领域 FIELD

[0001]本发明涉及电连接器领域,特别是涉及一种具有高差分特性阻抗的电连接器。 [0001] The present invention relates to the field of electrical connectors, and more particularly to an electrical connector having a high differential characteristic impedance.

背景技术 Background technique

[0002]在电连接器的一些应用领域中,相应系统的差分特性阻抗一般为100Q,为了保证差分传输信号的完整性,要求电连接器的差分特性阻抗必须与系统的差分特性阻抗相匹配,即要求电连接器的差分特性阻抗要达到100 Q。 [0002] In some applications in the field of electrical connectors, the differential characteristic impedance corresponding systems generally 100Q, in order to ensure the integrity of the differential transmission signal characteristic of the electrical connector requires differential impedance must match the characteristic impedance of a differential system, the electrical connector of claim i.e. a differential characteristic impedance to reach 100 Q. 根据差分特性阻抗的定义,在绝缘体材料和接触件间距确定的情况下,目前采用的解决措施是将与绝缘体的配合部分的直径减小,从而提高电连接器的差分特性阻抗,以满足与系统匹配的要求。 According to the definition of the differential characteristic impedance, in the case where the insulator material and the contact spacing is determined, the solutions currently used to reduce the diameter of the mating portion of the insulator, thereby increasing the characteristic impedance of a differential electrical connector to meet the system matching requirements.

[0003]上述措施虽然能够实现电连接器的100 Q差分特性阻抗,但是也同时带来了相应的弊端。 Although the [0003] above-mentioned measures enable electrical connector 100 Q differential characteristic impedance, but also brings the corresponding disadvantages. 首先,将接触件的部分直径变细以后,直接导致了其载流能力的下降,增大了电连接器的发热量;其次,显而易见的,当接触件的部分直径变细以后,势必会降低接触件的强度,这会使得接触件极易出现从与绝缘体的交界处折断的问题。 First, the diameter of the contact piece portion after thinning, lead directly to a decline in its current carrying capacity, increasing the amount of heat of the electrical connector; secondly, apparent When the diameter of the contact portion of the tapered member, is bound to reduce strength of the contact member, the contact member which would easily break problems from the junction of the insulator. 显然,通过上述措施来增大电连接器的差分特性阻抗是得不偿失的。 Obviously, to increase the differential characteristic impedance of the electrical connector through these measures is worth the candle.

[0004] 然而,即使是这样,上述措施也无法应用至一些存在内套和线簧丝等内部结构的接触件中,由于这一类接触件的外径必须满足一定的值,这将导致接触件的外径不能无限制的缩小,从而使采用该中接触件的电连接器的差分特性阻抗至今无法满足100Q。 [0004] However, even so, these measures can not be applied to some of the contact member is present within the internal structure of the sleeve and the wire spring wire or the like, since the outer diameter of this type of contact must meet a certain value, which will result in contact You can limit the outer diameter of the narrowing member, so that the differential characteristic impedance of the electrical connector contact member still can not satisfy 100Q.

[0005] 综上所述,目前的电连接器中采用的增大接触件差分特性阻抗的结构存在兼容性以及通用性差的问题,这使得目前的电连接器要么存在功率小、强度差的问题,要么存在差分特性阻抗低的问题。 [0005] In summary, compatibility and general problem of poor contact is increased characteristic impedance differential current configuration employed in the electrical connector, which makes the current of the electrical connector or the presence of small power, the problem of poor strength or there is the problem of low impedance differential characteristics. 强度和功率与差分阻抗特性之间对于目前的电连接器来说仍然是鱼与熊掌的关系。 The difference between strength and power and impedance characteristics for the current electrical connector is still a relationship between the fish and eat.

发明内容 SUMMARY

[0006] 本发明的目的在于提供一种具有高差分特性阻抗的电连接器,以在不降低接触件的功率和强度的前提下增大电连接器的差分特性阻抗。 [0006] The object of the present invention is to provide a high characteristic impedance differential electrical connector, to reduce the difference in the characteristic without increasing the premise of the electrical connector and power intensity of the contact resistance.

[0007] 为了解决上述问题,本发明的具有高差分特性阻抗的电连接器采用以下技术方案:具有高差分特性阻抗的电连接器,该电连接器以前端为插接端,其包括绝缘体和接触件,所述绝缘体为空心结构,其包括前、后侧壁以及连接在前、后侧壁之间的围壁,接触件沿前后方向穿透所述的绝缘体并被固定在绝缘体的前侧壁和/或后侧壁上。 [0007] In order to solve the above problems, the electrical connector having a high impedance differential characteristic of the present invention employs the following technical solution: an electrical connector having a high-impedance differential characteristic, the electrical connector to the distal end of the plug end, and which includes an insulator contact, the insulator is a hollow structure, which comprises a front, rear and side walls connecting the front and rear side walls between the surrounding wall, the contact member penetrating the longitudinal direction of the insulator and the insulator is fixed to the front side wall and / or rear wall.

[0014]所述绝缘盖体与绝缘盒体上分别设有相应的工艺孔。 [0014] The insulating member and the insulating cover on each cartridge is provided with apertures corresponding process.

[0015]由于该具有高差分特性阻抗的电连接器的绝缘体为空心结构,并且接触件沿前后方向穿透所述的绝缘体并被固定在绝缘体的前侧壁和/或后侧壁上。 [0015] Since the characteristic impedance of the high differential electrical connector insulating hollow structure, and the contact of the front-rear direction of the insulator penetrates the insulator and is fixed to the front side wall and / or rear wall. 这使得接触件的位于绝缘体中的部分周围的绝缘介质成为了空气,根据差分特性阻抗的定义,在绝缘体材料和接触件间距确定的情况下,可通过降低介质材料的介电常数来提高差分特性阻抗,而空气的介电常数相对来说是最小的,因此,该电连接器可以在不改变原有接触件的直径的情况下提高差分特性阻抗,由此可见,该电连接器能够在不降低接触件的功率和强度的前提下增大电连接器的差分特性阻抗。 This makes the dielectric insulator positioned around the contact portion of the air becomes, according to the definition of the differential characteristic impedance, in the case where the insulator material and the contact spacing is determined, the differential characteristics can be improved by reducing the dielectric constant of the dielectric material impedance, and the relative dielectric constant of air is minimal, and therefore, the electrical connector can be improved without changing the characteristic impedance of the differential case where the diameter of the original contacts, Thus, the electrical connector can not the electrical connector is increased differential characteristic impedance premise reduced power and the strength of the contact member.
