电源插头 Power plug
本实用新型是一种电源插头。 The present invention is a power plug.
现有的电源插头可从图1和图4上看到，其中图1是主视图、图4是图1中的AA剖视图。 The conventional power plug can be seen from FIGS. 1 and 4, wherein FIG. 1 is a front view, FIG. 4 is a sectional view AA of FIG. 它包含有盖1、基座2、插销3、接线柱4、连接螺钉5、压线板6、紧固螺钉7，其中插销同接线柱的结构还可从图5中看到，图5中(c)图是两者连接一体时的主视图、(d)图是(c)图中的BB剖视图。 It comprises a cap 1, a base 2, pin 3, terminal 4, 5 connected to the screw, the pressure plate line 6, the fastening screws 7, wherein the plug with the stud structure may be seen from FIG. 5, FIG. 5 (c) is a front view of FIG both integrally connected, (d) is a sectional view BB of FIG. (c) of FIG. 从图中看到插销是一块上宽下窄的T字形薄片，接线柱呈圆环柱形，两者以铆合连成一体，并且接线柱的外圆面直径小于插销的上部宽度。 Seen from FIG latch is wider at a T-shaped sheet post has an annular cylindrical, integrally connected both to riveting, and the outer circumferential surface is smaller than the diameter of the upper portion of the width of the terminal latch. 该电源插头的缺点是：1)插销在基座插孔中的安装定位面是其上部的两个侧壁，该两侧壁因壁薄且插孔高度有限，所以该定位不能有效地克服插销在插拔过程中的晃动力，因此插销容易松动，从而影响到接插工作的稳定性和可靠性；2)接线柱同插销的铆合结构较为复杂、工艺较麻烦且对铆合要求较高，因此制造成本也提高。 A disadvantage of this plug is that: 1) the positioning pin mounting surface of the base socket is the upper part of two side walls, the side walls and by a thin wall jack height is limited, it can not effectively overcome the positioning pin shaking force plug process, thus easy to loose bolt, which affects the stability and reliability of work of the patch; 2) with the terminal pin riveting complicated structure of the process is relatively cumbersome and demanding riveting Therefore the manufacturing cost increase.
本实用新型的目的是要克服上述现有技术中存在的缺点，提供一种结构简单、制造成本低且接插工作稳定、安全可靠的电源插头。 The object of the present invention is to overcome the above disadvantages present in the prior art, providing a simple structure, low manufacturing cost and patch stable, safe and reliable power plug.
本实用新型电源插头包含有盖、基座、插销、接线柱，它的特点是：插销是等宽的条形片，位于其上部的接线柱是与插销等宽的立方体，同时基座内带有与接线柱的横截面形状、大小相匹配的插孔。 The present invention includes a plug lid, the base, pin, post, which is characterized by: a plug strip sheet width, at its upper portion is wide terminals with the latch like a cube, while the base strip cross-sectional shape of the terminal, the size of matched receptacle. 接线柱可以是正方体，也可以是长方体，并且它与插销呈连体形。 Cube may be terminal, may be a rectangular parallelepiped, and it was connected with the latch body.
下面将通过实施例并对照附图，对本实用新型电源插头作进一步的叙述。 The following examples and reference to the drawings, the power plug of the present invention is further described below. 附图内容有：图1是本实用新型电源插头的主视图；图2是图1中的AA剖视图；图3是本实用新型电源插头中的接线柱同插销的结构图，其中(a)是它们的主视图、(b)是(a)中的CC剖视图；图4是现有电源插头去盖以后的俯视图，因现有电源插头的主视图与本实用新型中的图1相同，所以图4也可以是图1中的AA剖视图；图5是现有电源插头中的接线柱同插销的结构图。 BRIEF SUMMARY are: FIG. 1 is a front view of the power plug of the present invention; FIG. 2 is a sectional view AA of FIG. 1; FIG. 3 is a configuration diagram of the power plug of the present invention with the latch in the terminal, wherein (a) is they are a front view, (b) is (a) a sectional view CC in; FIG. 4 is a plan view after a conventional power plug to cover the same because a front view of the conventional power plug to the present invention in FIG. 1, the FIG. 4 may be a cross-sectional view AA of FIG. 1; FIG. 5 is a configuration diagram of a conventional power plug terminal of the same latch.
从图1和图2上看到，本实用新型电源插头包含有盖1、基座2、两者以螺钉5连接成一体。 Seen from Figures 1 and 2, the present invention includes a plug cap 1, a base 2, both of a screw 5 are integrally connected. 插销3和接线柱4还可从图3中看到，前者是等宽的条形片，即上、下的宽度相同，后者是一个带有顶紧螺钉7的长方体或正方体，并且接线柱与插销等宽、两者连体。 Terminal pin 3 and 4 can also be seen from FIG. 3, the former is the width of the strip sheet, i.e. the same width as the lower, with a top which is a rectangular parallelepiped or a cube screws 7, and the post width with the latch, the two piece. 基座2内带有三个插孔，并且每一个插孔的横截面均与接线柱的横截面相匹配。 In the base 2 with three jacks, each jack and the cross-section are matched to the cross section of the stud. 基座在电线出口端上还带有一块压线板6，用于压住电源线，使其稳定在电源插头上。 Base on the wire outlet side a pressure line with a further plate 6 for pressing the power line, in the stabilized power plug.
本实用新型电源插头在使用安装时，先将连体的插销、接线柱插入基座内的插孔中，再将电源线端的三芯线分别穿入接线柱上的圆孔中并以顶紧螺钉7紧固，电源线另端从图2中基座右侧的内孔中穿出，且用压线板6将其稳固，然后把盖1同基座合上，再用螺钉5紧固即可。 The present invention is in use installed plug, the first latch piece, inserted into the jack terminals in the base, then the power supply line side conductor cord penetrates the circular hole, respectively on the terminals and a top tight fastening screws 7, the other end of the power cord out through the inner bore of the base on the right side in FIG. 2, and the plate with a pressure line 6 to a solid, and then put the cover 1 engaged with the base, and then fastening screws 5 It can be.
本实用新型的优点是：1)接线柱以其方形或长方形的三个侧壁P、Q、M与基座插孔壁贴合定位，并且插销与接线柱连体，因此电源插头在使用中其插销不易晃动，从而使接插工作稳定、可靠；2)接线柱同插销的连体结构使插头加工量减小、成本降低。 The advantages of the present invention are: 1) square or rectangular in its terminal three sidewalls P, Q, M bonded to the base with the receptacle wall positioned, and the plug with the terminal piece, and therefore, in use, the power plug rock bolt which is not easy, so that the plug stable and reliable; 2) post-piece structure with the plug pin of the processing volume is reduced, to reduce costs.
