Description
技术领域technical field
本发明属于电网设备技术领域，特别涉及一种钎焊铜铝过渡压接线夹。The invention belongs to the technical field of power grid equipment, in particular to a brazing copper-aluminum transition crimping clamp.
背景技术Background technique
早期铜铝过渡对焊压接线夹由于受运行环境的限制，如多风地区导线的摆动给予线夹对焊处额外的拉力，长期运行易造成线夹对焊处折断，造成相间放电故障。The early copper-aluminum transition butt welding clamps were limited by the operating environment, such as the swing of the wires in windy areas, which gave the clamps additional tension on the welding joints. Long-term operation may easily cause the joints of the clamps to break and cause phase-to-phase discharge faults.
目前对铜铝过渡对焊压接线夹进行更换的方法主要有以下三种：一、从原压接线夹尾部截断，不换导线的情况下，加装过渡板，这种方法会增加接触点，使隔离开关整体回路电阻增大；二、更换包括压接线夹在内的整根导线，这样会加大成本，而且有些导线与线路架空下为一体，不宜更换。三、将压接线夹从导线上剔除，保留原导线长度，重新压接新线夹，这种方法费时费力，而且不能保证原导线压接部位平整，易造成压接部位过热。At present, there are mainly three methods for replacing the copper-aluminum transition butt welding crimping clamp: 1. Cut off from the tail of the original crimping clamp, and install a transition plate without changing the wire. This method will increase the contact point. Increase the overall circuit resistance of the isolating switch; 2. Replace the entire wire including the crimping clamp, which will increase the cost, and some wires are integrated with the overhead line, which is not suitable for replacement. 3. Remove the crimping clip from the wire, keep the original wire length, and re-crimp the new clip. This method is time-consuming and laborious, and it cannot ensure that the crimping part of the original wire is flat, and it is easy to cause overheating of the crimping part.
因此，急需一种既能满足在不需要更换导线的前提下，线夹更换方便、耗费时间短，又与导线具有较高结合强度的新型铜铝过渡压接线夹。Therefore, there is an urgent need for a new type of copper-aluminum transitional crimping clamp that can meet the needs of replacing the wire without changing the wire, which is convenient to replace, takes a short time, and has a higher bonding strength with the wire.

在本发明提供的钎焊铜铝过渡压接线夹中，由于空心部11和实心部12相连部位的空心部11的管壁上具有孔14，因此，在往空心部11内压接导线时，可以通过孔14观察导线是否压接到位，从而可以快速、直观地确定导线是否压接到位，因此，提高了操作效率，节约了操作时间。In the brazed copper-aluminum transition crimping clamp provided by the present invention, since the hollow part 11 has a hole 14 on the tube wall of the connecting part of the hollow part 11 and the solid part 12, when the wire is crimped into the hollow part 11, Whether the wires are crimped in place can be observed through the hole 14, so that it can be quickly and intuitively determined whether the wires are crimped in place, thus improving operation efficiency and saving operation time.
同时，由于空心部11和实心部12相连部位的空心部11的管壁上具有孔14，在用新的本发明的钎焊铜铝过渡压接线夹更换掉旧的本发明的钎焊铜铝过渡压接线夹时，可以快速、准确地找到空心部11和实心部12的相接部位(也即，导线在钎焊铜铝过渡压接线夹的空心部11中压接的深度位置)，并在此位置处截断导线压接部1，而不会误将导线截断；同时，由于孔14的存在，可以使在空心部11和实心部12的相接部位截断导线压接部1的操作更加容易，从而节省了操作时间，也进一步降低了成本。Simultaneously, since there is a hole 14 on the tube wall of the hollow part 11 at the connecting part of the hollow part 11 and the solid part 12, the old brazed copper-aluminum of the present invention is replaced with the new brazed copper-aluminum transition crimping clip of the present invention When the transitional crimping clamp is used, the junction of the hollow part 11 and the solid part 12 can be quickly and accurately found (that is, the depth position where the wire is crimped in the hollow part 11 of the brazing copper-aluminum transitional crimping clamp), and Cut off the wire crimping part 1 at this position, and the wire will not be cut off by mistake; at the same time, due to the existence of the hole 14, the operation of cutting the wire crimping part 1 at the junction of the hollow part 11 and the solid part 12 can be made easier.

Further preferably, the number of holes 14 is at least two, preferably 3-12, more preferably 6-9, such as 3, 4, 5, 6, 7, 8, 9, 10 , 11 or 12.
在本发明提供的钎焊铜铝过渡压接线夹中，由于在空心部11的开口端的管壁上具有开口13，使得空心部11的开口可以适度扩张，从而在空心部11内可以插入比空心部11的中空管状结构的管口内径稍大的导线，而且插入导线的操作更为容易。而在空心部11内插入比空心部11的中空管状结构的管口内径稍大的导线，可以增加导线和空心部的接触面积以及导线和本发明提供的钎焊铜铝过渡压接线夹之间的结合牢固程度。同时，当导线完全插入空心部11后，还可以在空心部11的外部使用紧固带将空心部11具有开口的部位紧固，使得导线和钎焊铜铝过渡压接线夹的连接更为牢固。In the brazed copper-aluminum transition crimping lug provided by the present invention, since there is an opening 13 on the tube wall at the opening end of the hollow part 11, the opening of the hollow part 11 can be moderately expanded, so that the hollow part 11 can be inserted into the hollow part 11 The inner diameter of the nozzle of the hollow tubular structure of the part 11 is slightly larger, and the operation of inserting the wire is easier. And in the hollow part 11, insert a wire slightly larger than the nozzle internal diameter of the hollow tubular structure of the hollow part 11, can increase the contact area between the wire and the hollow part and between the wire and the brazing copper-aluminum transition crimping clamp provided by the present invention the firmness of the bond. At the same time, when the wire is completely inserted into the hollow part 11, a fastening tape can also be used outside the hollow part 11 to fasten the opening of the hollow part 11, so that the connection between the wire and the brazing copper-aluminum transition crimping clamp is more firm .

Meanwhile, there may be one opening 13, or at least two (ie: two or more than two). When there are at least two openings 13 , preferably each opening is evenly distributed on the tube wall of the hollow portion 11 . For example, there may be three openings 13, which are evenly distributed on the tube wall of the hollow part 11.
在本发明提供的钎焊铜铝过渡压接线夹中，由于导线压接部1分为空心部11和实心部12，空心部11可以压接导线，实心部12与接线板2紧密连接，使得导线压接部1既由于空心部11的存在满足了压接导线的功能，又由于实心部12的存在，有效地保证了本发明的钎焊铜铝过渡压接线夹的强度和载流量。同时，由于实心部12的存在，直接增加了钎焊铜铝过渡压接线夹的长度，在更换现有技术中的只具有压接管而无实心部的钎焊铜铝过渡压接线夹时，由于本发明提供的钎焊铜铝过渡压接线夹有多出的实心管部12来填补导线的缺失长度，所以在更换钎焊铜铝过渡压接线夹时，可以从原钎焊铜铝过渡压接线夹的尾部截断导线，然后直接将导线压接到本发明的钎焊铜铝过渡压接线夹的空心管部11即可，而无需更换导线，从而降低了成本。In the brazing copper-aluminum transition crimping clamp provided by the present invention, since the wire crimping part 1 is divided into a hollow part 11 and a solid part 12, the hollow part 11 can crimp the wire, and the solid part 12 is closely connected with the terminal board 2, so that The wire crimping part 1 not only satisfies the function of crimping wires due to the existence of the hollow part 11, but also ensures the strength and current carrying capacity of the brazed copper-aluminum transition crimping clamp of the present invention effectively due to the existence of the solid part 12. At the same time, due to the existence of the solid part 12, the length of the brazed copper-aluminum transition crimping clamp is directly increased. The brazed copper-aluminum transition crimping clamp provided by the present invention has an extra solid tube portion 12 to fill the missing length of the wire, so when replacing the brazed copper-aluminum transition crimping clamp, the original brazing copper-aluminum transition crimping wire can be used The tail part of the clip cuts off the wire, and then directly crimps the wire to the hollow tube part 11 of the brazed copper-aluminum transition crimping clamp of the present invention without replacing the wire, thereby reducing the cost.
优选地，在本发明提供的钎焊铜铝过渡压接线夹中，空心部11和实心部12的长度相等。进一步优选地，空心部11和实心部12的长度均为130mm。这样可以在用新的本发明的钎焊铜铝过渡压接线夹更换掉旧的本发明的钎焊铜铝过渡压接线夹时，可以方便地从旧的本发明的钎焊铜铝过渡压接线夹中导线压接部1的中间位置(即空心部11和实心部12的结合处)截断，再将导线从空心部剥离之后即可方便地将导线压接到一个新的本发明的钎焊铜铝过渡压接线夹的导线压接部的空心部，这样使得在不更换导线的前提下，还可以保持原导线的松紧度，以及导线与本发明的钎焊铜铝过渡压接线夹的压接长度与压接质量。Preferably, in the brazed copper-aluminum transition crimping clip provided by the present invention, the lengths of the hollow part 11 and the solid part 12 are equal. Further preferably, the lengths of the hollow part 11 and the solid part 12 are both 130 mm. In this way, when the old brazed copper-aluminum transition crimping clip of the present invention is replaced with the new brazing copper-aluminum transition crimping clip of the present invention, the old brazing copper-aluminum transition crimping wire of the present invention can be easily replaced. The middle position (i.e. the junction of the hollow part 11 and the solid part 12) of the wire crimping part 1 in the clamp is cut off, and the wire can be easily crimped to a new soldering joint of the present invention after the wire is stripped from the hollow part.
