Description
[technical field]
The utility model relates to data and transmits joint, especially a kind of test splice with shielding construction.
[background technology]
In order to ensure transmission quality, HMDI terminal is all provided with corresponding shielding construction.Existing HMDI terminal, its cable clamp is located at outside front shielding case, cause between forward and backward shielding case and produce annular gap, as shown in Figure 6, in order to solve the annular gap between forward and backward shielding case, usually after forward and backward shielding case riveting, on annular gap, scolding tin is filled by the mode of welding, form tin ring, thus effectively can shield interference signal, to ensure that transmitted data have high-quality.But this settling mode compares wastes time and energy, again because HDMI terminal is subject to secondary high-temperature when welding, wire rod electrical property is then deteriorated.
In addition, as shown in Figure 7, because cable clamp is located at outside front shielding case, the screen point on screen pin contiguous block is then opened, and therefore, screen pin needs correspondingly to bend, and adopts the screen pin of warp architecture, and its impedance behavior is deteriorated, and can not meet the requirement for transmitting HMDI signal.
Namely the utility model is researched and proposed for the deficiencies in the prior art.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of test splice with shielding construction, front shielding case is sleeved on screen pin contiguous block, cable clamp is embedded in front shielding case, rear screening cover is sleeved on shaping contiguous block, namely front shielding case and rear screening cover realize slitless connection after riveting, effectively shield interference signal to impact of the present utility model, screen pin linearly type, on screen pin contiguous block, all screen pins are parallel to each other, improve impedance behavior, to meet the resistance requirements of HDMI signal high-frequency transmission.In addition, it is little that the utility model also has design volume, manufactures easy and that cost is low feature.
For solving the problems of the technologies described above, a kind of test splice with shielding construction of the utility model, adopts following technical scheme:
A kind of test splice with shielding construction of the utility model, comprise and be located at cable and damper ends and the shaping contiguous block be connected with cable one, described shaping contiguous block is provided with the cable clamp for arranging the heart yearn in cable, described cable clamp is connected with screen pin contiguous block, described screen pin contiguous block is provided with the screen pin be electrically connected with heart yearn, described screen pin contiguous block is set with for shielding shielding case before interference signal, described cable clamp is embedded in front shielding case, described shaping contiguous block is set with the rear screening cover with front shielding case slitless connection.
Described screen pin linearly type, on described screen pin contiguous block, all screen pins are parallel to each other.
Described rear screening cover is provided with PVC shell.
Described front shielding case is also connected with dust cover.
Described cable clamp is provided with some draw-in grooves for the heart yearn in card close-packed array cable.
Compared with prior art, a kind of test splice tool with shielding construction of the utility model has the following advantages:
1, namely front shielding case and rear screening cover realize slitless connection after riveting, effectively can shield interference signal to impact of the present utility model, and avoid welding generation secondary high-temperature, cause the problem that wire rod electrical property is deteriorated;
2, shield pin linearly type, on screen pin contiguous block, all screen pins are parallel to each other, and improve impedance behavior, to meet the resistance requirements of HDMI signal high-frequency transmission;
3, cable clamp is embedded in front shielding case, makes global design smaller volume;
4, without the need to carrying out welding sequence again, easy and that cost is low feature is manufactured.

[embodiment]
Below in conjunction with accompanying drawing, execution mode of the present utility model is elaborated.
A kind of test splice with shielding construction of the utility model, comprise and be located at cable 1 end and the shaping contiguous block 2 be connected with cable 1 one, described shaping contiguous block 2 is provided with cable clamp 3, described cable clamp 3 is provided with some draw-in grooves 31 for the heart yearn 11 in card close-packed array cable 1, described cable clamp 3 is connected with screen pin contiguous block 4, described screen pin contiguous block 4 is provided with the screen pin 5 be electrically connected with heart yearn 11, described screen pin contiguous block 4 is set with for shielding shielding case 6 before interference signal, described cable clamp 3 is embedded in front shielding case 6, global design volume can be reduced, described shaping contiguous block 2 is set with the rear screening cover 7 with front shielding case 6 slitless connection, namely no longer needs between front shielding case 6 with rear screening cover 7 to be connected with tin ring 12, to improve shield effectiveness.Front shielding case 6 and rear screening cover 7, by slitless connection after riveting, can reach the jamproof performance requirement of HDMI signal high-frequency transmission.
In order to improve impedance behavior, described screen pin 5 linearly type, on described screen pin contiguous block 4, all screen pins 5 are parallel to each other, and make it the requirement that impedance meets HDMI signal high-frequency transmission.
Described rear screening cover 7 is provided with PVC shell 71, PVC shell 71 and extends on front shielding case 6, makes it to form test splice.
Described front shielding case 6 is also connected with dust cover 61, and when when not using, dust cover 61 is enclosed within front shielding case 6, screen pin 5 can be avoided to be stained with dust, and impact uses.
