[0022] Example
[0023] See also Figure 1 The present embodiment discloses a short-circuit cap for realizing a short circuit at the end of an electrical connector plug 6. The short-circuit cap comprises: a shell 1, an elastic member and a contact cap 3. The middle part of the shell 1 is a receiving cavity 12 with one side open. The shell 1 is provided with a connecting portion connected to the end of the electrical connector plug 6. One end of the elastic member is fixed in the receiving cavity 12 of the shell 1. The contact cap 3 is fixed to the other end of the elastic member. The shell 1, the elastic member and the contact cap 3 are all made of conductive materials.
[0024] As an optional embodiment, the elastic member is a spring 2, which is a standardized product and can always maintain contact with the pin 5 in environments such as vibration and impact, thereby playing a conductive role. A first mounting groove 11 is provided at the bottom of the accommodating cavity 12 of the shell 1, and one end of the spring 2 is engaged in the first mounting groove 11, and is tightly attached to the inner wall of the shell 1 through the radial elastic force of the spring 2. A second mounting groove 32 is provided on the contact cap 3, and the other end of the spring 2 is engaged in the second mounting groove 32, so that the three parts form a whole. Preferably, the other end of the spring 2 is loosely matched with the second mounting groove 32, so that the contact cap 3 can rotate and deflect freely in the spring 2. Furthermore, a label 4 is also fixed to the shell 1.
[0025] As an optional embodiment, a sinking groove 31 is provided on one end surface of the contact cap 3 away from the housing 1, and the bottom of the sinking groove 31 is a concave arc surface 311. Figure 2When in use, the sinking groove 31 of the contact cap 3 must ensure that the pin 5 is completely wrapped, and then the housing 1 is installed on the end of the electrical connector plug 6 to assemble the product in place. Under the elastic force of the spring 2, the contact cap 3 and the pin 5 are always in reliable contact. Depending on the type of product, the connection between the housing 1 and the end of the electrical connector plug 6 can be changed to a slot connection, a threaded connection, or other connection methods. Figure 1 A thread 13 is provided on the inner wall of the middle shell 1 .
[0026] Preferably, the housing 1 should be processed with metal materials or non-metal materials with excellent cutting performance, such as 45 steel, brass, PPS (polyphenylene sulfide), etc. The spring 2 is made of spring 2 steel with excellent elasticity and needs to take into account the conductive performance. The material with too large unit resistance cannot be used. The contact cap 3 is processed with metal with excellent conductive performance and easy mechanical processing, such as lead brass (HPb59-1).
[0027] The above improved design of the short-circuit cap solves the shortcomings of the existing short-circuit cap, such as complex structure, high cost and long production cycle. The short-circuit cap provided by this embodiment has a simple structure, reliable performance, low cost, short production cycle and convenient use. It is changed from 6 parts to 4 parts, and the improved product can be processed by an ordinary lathe. The original product also requires a milling machine for auxiliary processing, and the parts processing technology is more complicated. The original short-circuit cap is also designed with an insulating mounting plate (i.e., a base), which needs to be put into a mold for processing. The improved short-circuit cap is simpler in the parts processing technology, does not need to be put into a mold, and omits the special process of welding in assembly, making the product quality more stable and reliable.
[0028] The above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
